fix: refresh device versions on heartbeat (mobile-scanners 1.6)

An in-place app or OS update left the device record and every later scan reporting the enrollment-time appVersion, because only enrollment wrote manufacturer/model/osVersion/appVersion. Extension 1.6 adds the same optional fields to MobileScannersHeartbeatRequestV1; the heartbeat updates the approved device record only when a sent value differs, and scans copy the refreshed record. Omitted, null or blank values keep the enrolled values. Adds the 1.6.0 OpenAPI baseline and contract tests. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

 # QQQ Mobile Scanners

-Server support for approved Android handhelds running native QQQ apps. The first app, **Scan Capture**, stores barcode events in a QQQ table.

+## Where things live

-## Project layout
+Gitea is the primary forge for source, reviews and checks. GitHub is a shadow/archive that receives no ordinary writes; any GitHub link in an older document is history only.

- `src/main`: reusable qbit, device enrollment routes, device approval/revocation, scan process and table metadata.
- `src/test`: server behavior and permission checks.
- `demo`: local QQQ server with persistent H2 storage, native administration UI and password login.
- `e2e`: browser acceptance tests against the packaged frontend and isolated real demo server.
- `docs/TC22-ACCEPTANCE.md`: build, install and hardware verification.
+- Server (this repository): [git.kof22.com/QRun-IO/qbit-mobile-scanners](https://git.kof22.com/QRun-IO/qbit-mobile-scanners), development branch `develop`.
+- Android host: [git.kof22.com/QRun-IO/qqq-android](https://git.kof22.com/QRun-IO/qqq-android) (`scanner-host` module). Its reviews 8 and 10 are merged into `main`.
+- Current status: [session state](docs/SESSION-STATE.md), [TODO](docs/TODO.md), [production readiness](docs/PRODUCTION-READINESS.md). Older logs are in [history](docs/history/README.md).

-## Build
+## Current versions

-Use Java 21 and Maven 3.9+. The implementation targets QQQ `4.1.0-RC.20`; QQQ `4.0.0` does not provide the password session exchange needed by this demo.
+| Component | Version |
+| --- | --- |
+| Java / Maven | 21 / wrapper-pinned 3.9.9 |
+| QQQ | `4.1.0-RC.21` (public) |
+| QQQ semantic UI/UX API | 1.10 |
+| `mobile-scanners` extension | 1.5 |
+| `printing` extension (Echo) | 2.3, released Printing `1.0.0` |
+| `mobile-record-files` vocabulary | 1.0 |
+| Development snapshot | `0.1.0-20261103.233448-3645` (Central; development only) |
+
+The 198-test cohort for this set passes with Checkstyle (scanner 53, demo 8, mobile Record Files 18, Printing bridge 16, Echo 68, Echo demo 35). The document, Record Files and Scripting owner artifacts used by Echo are not yet public; see [session state](docs/SESSION-STATE.md).
+
+## Quick start

 ```powershell
 .\mvnw.cmd verify install
 .\mvnw.cmd -f demo/pom.xml verify
+pwsh -File scripts/Start-Demo.ps1
 ```

-The wrapper pins Maven 3.9.9. On Unix, use `./mvnw` in place of `mvnw.cmd`. This is an initial implementation, with no published Maven artifact. Consult [session state](docs/SESSION-STATE.md) for actual verification status.
+On Unix use `./mvnw`. The last command starts the basic Scan Capture demo on loopback. [Local demo](docs/LOCAL-DEMO.md) explains the two launchers (basic Scan Capture versus the full Echo server), signing in without displaying passwords, connecting a device or emulator, and the enroll, approve, scan and revoke walkthrough. For a physical handheld follow [TC22 acceptance](docs/TC22-ACCEPTANCE.md); for test runners see [testing](docs/TESTING.md). Checkstyle runs during `validate`; do not disable it or skip tests.

-For the Windows demo, follow [local startup and credentials](docs/LOCAL-DEMO.md). For the scanner, follow [TC22 installation and acceptance](docs/TC22-ACCEPTANCE.md).
+## Architecture

-See [process acceptance tests](docs/TESTING.md) for server, browser, and native Android E2E commands. Approval and revocation support record actions and bulk selections with a confirmation and visible result.
+The server uses QQQ's existing, versioned semantic UI/UX API; nothing parallel is added.

-## Customer branding and connection diagnostics
+- App discovery and process execution go through `/qqq/v1`.
+- Enrollment, branding and status are registered operations of the independently versioned `mobile-scanners` extension at `/qqq/v1/qbit/mobile-scanners`, with discovery, stable operation IDs and typed OpenAPI schemas. The Android host checks core and extension compatibility before login. See the [semantic API contract](docs/UI-API.md).
+- The qbit contributes `mobileDevice`, private device credential storage, `mobileScan`, `mobileScanCapture`, the scanner widget and the device approve/revoke processes. Device sessions, live activity and consented screen viewing are in [device sessions](docs/DEVICE-SESSIONS.md) and [screen viewing](docs/DEVICE-SCREEN-VIEWING.md).
+- Metadata changes that use supported native components reach devices from the server; a new required component type needs a shared Android update. This does not imply full web-client feature coverage.

-Configure the customer name, primary color and optional HTTPS logo on the server; the same Android APK applies them before login and throughout the mobile screens. See [branding configuration](docs/BRANDING.md). The shared launcher remains QQQ Mobile.
+```text
+Android host --(/qqq/v1 + mobile-scanners extension)--> QQQ server + this qbit --> H2/RDBMS
+                                                         |-- optional: Echo, Record Files, Document Generation, Printing
+```

-The app footer checks server reachability while foregrounded. Tap it to inspect and copy recent safe diagnostic events. The public status endpoint reports reachability independently of user authentication and device approval.
+## Project layout

-## Contributing and CI
+- `src/main`, `src/test`: the reusable qbit (enrollment routes, approval/revocation, scan process, table metadata) and its H2 behavior and permission tests.
+- `demo`: basic local QQQ server with persistent H2 storage, native administration UI and password login. QQQ `4.0.0` lacks the password session exchange it needs.
+- `e2e`: browser acceptance tests against the packaged frontend and an isolated real demo server.
+- `examples/echo` and `examples/echo/demo`: the optional Echo library and its runnable composed server.
+- `integrations/record-files`: optional camera/gallery upload bridge.
+- `scripts`: Windows launcher and the password-copy helper.

+## Supported features
+
+- Single-barcode capture (Zebra EMDK service on the Android host, no DataWedge profile) and manual entry for Scan Capture, with QQQ table-based login.
+- Device enrollment, approval and revocation from a record or from bulk selection (checked rows, select-all, first N up to 100), with confirmation and visible results.
+- Idempotent scan events, device/session records, online activity, administrator session termination, own-app screen viewing, optional foreground location, and customer branding with connection diagnostics ([branding](docs/BRANDING.md)).
+- Optional operator-consented device-screen viewing (extension 1.2), camera/gallery record uploads through the optional [Record Files bridge](integrations/record-files/README.md), and the Echo scan-to-print example.
+- Additional apps are ordinary QQQ app/process/widget metadata; their server-side permission rules must explicitly protect their actions.

 ## Embed in a QQQ application

-Enable `instance.setEnforcePermissionsInCoreActions(true)`, register `MobileScannersQBitProducer` with a host-owned persistent backend, and attach `MobileScannersRouteProvider` to the QQQ Javalin server. The qbit requires core permission enforcement so direct table actions cannot bypass its protections. Grant `mobile.scan` to operators and `mobile.admin` to administrators through the host's identity provider/permission integration. The demo's fixed account roles are confined to the demo application.

-The API uses the normal QQQ user session plus `X-QQQ-Device-Id` and `X-QQQ-Device-Token`. Device credentials are not process input fields. Enrollment creates a pending device; approval enables app access, and revocation prevents subsequent captures. Lost local app data requires fresh enrollment and administrator review.
+Generic table mutations are blocked; device lifecycle and capture go through guarded operations. The API uses the normal QQQ user session plus `X-QQQ-Device-Id` and `X-QQQ-Device-Token`; device credentials appear only in those scoped headers and in private hashed storage, never in process inputs, responses beyond enrollment, fixtures or logs. Enrollment creates a pending device, approval enables app access and revocation prevents later captures. An installation identifier is descriptive, not a credential. Lost app data requires fresh enrollment and administrator review.

 ## Scan semantics

-Each physical scan receives a new event UUID. A retry of that event uses the same UUID and returns the original receipt rather than inserting a second record. Scanning the same barcode twice intentionally produces two events.
+Each physical scan gets a new event UUID. A retry reuses that UUID and returns the original receipt; scanning the same barcode twice deliberately creates two events. Stored data includes barcode text (leading zeroes preserved), symbology, source, capture and receipt times, authenticated user, approved device, app and process, and reported hardware/app versions; extension 1.5 can add the scanner's AIM identifier and exact raw bytes. Client-reported timestamps and hardware details are provenance, not identity. The app shows success only after server acknowledgement, a timeout is an uncertain outcome to retry, and there is no offline queue.

-Stored data includes barcode text, symbology, source, device capture time, server receipt time, authenticated user, approved device, app/process and reported hardware/app versions. Barcode text is preserved, including leading zeroes. Client-reported timestamps and hardware information are provenance, not trusted identity.
+## Limits and release status

-The app must show server acknowledgement before reporting a save. A network timeout has an uncertain outcome; retry the retained event. There is no persistent offline queue in this version.
+- **Not production-ready.** The local demo works and the TC22 manual tests are operator-reported as passing; a QRun-signed Android 1.0 APK and its direct/MDM channel exist locally, but signed-build qualification on a device against an HTTPS server, distribution, HTTPS deployment and the other [readiness gates](docs/PRODUCTION-READINESS.md) are open. The HTTP loopback demo and an HTTPS production deployment are separate things.
+- **Barcode fidelity.** Echo supports a documented set of symbologies and refuses GS1, ECI, structured and binary payloads ([limits](examples/echo/README.md#fidelity-and-limits)); no universal reproduction or all-symbology claim is made. Hardware AIM output has no separate evidence beyond the operator's group report.
+- **Dependencies.** The development snapshot is published, but the document/files/scripting owner artifacts are not; Echo and the Record Files integration need a coherent local cohort until they are.
+- **Outside this version:** offline workflows, camera-based decoding, a visual app designer and applied MDM rollout. The Android host implements managed configuration, a profile generator and a live wallpaper, but applied rollout is not qualified. Native OAuth2 login exists only for servers that advertise the semantic UI API 1.10 native-session and nonce-validation features; no native handheld test against a configured provider (such as Authentik) is claimed, and that acceptance plus production ingress hardening remain gates.
+- **Database.** The supplied schema targets H2; migrations for other databases belong to the host application.

-## Scope
+## Contributing and CI

-The tested handheld path uses single-barcode Zebra DataWedge delivery and QQQ table-based login. The Android client also implements metadata-advertised native OAuth2 login for servers providing the explicit UI API 1.9 contract; configured-provider acceptance and production scanner-ingress hardening remain release gates. See the client's [authentication guide](https://github.com/QRun-IO/qqq-android/blob/feature/mobile-scanner-host/docs/AUTHENTICATION.md).
-
-Device/session records, online activity, administrator session termination, own-app screen viewing and optional foreground location are implemented. Extension1.2 adds optional [operator-consented device-screen viewing](docs/DEVICE-SCREEN-VIEWING.md); actual Android projection acceptance remains open. Camera/gallery record uploads use the optional Record Files bridge and require its compatible dependency tuple; production publication and actual camera acceptance remain open. Additional apps use QQQ's native process/widget metadata, and their server-side permission rules must explicitly protect their actions.
-
-A visual mobile app designer, offline workflows, camera-based barcode decoding and applied MDM rollout remain outside this version. Company profile/wallpaper options are researched in the client's provisioning guide. The supplied SQL schema targets H2; other database migrations belong to the host application.
+Development pull requests target `develop`; `main` is reserved for reviewed releases. All Maven publication switches other than development snapshots stay disabled, and creating a repository or pushing a branch is not permission to publish. The CircleCI and GitHub workflow files describe the retained legacy shared QBit pipeline; [CI and release operation](docs/CI-CD.md) explains how to run the same checks locally, and the local demo does not depend on that pipeline.

+# CI helper crash handoff (Windows helper job)
+
+Scope: PSScriptAnalyzer 1.25.0 throws NullReferenceException on
+`integrations/record-files/Verify-Isolated.ps1` only (root reproduced; the other
+five analyzed scripts report zero findings). Run 41337798368 was the hosted failure.
+
+## Changes
+
+- `integrations/record-files/Verify-Isolated.ps1`: the final two statements built
+  one-line hashtables containing a `$(if ... else ...)` subexpression and several
+  nested `(Get-FileHash ...)` calls, piped directly to `ConvertTo-Json`. That is
+  the only construct in the repository's scripts combining those features, and
+  the alignment/whitespace rules inspect hashtable key/value extents. The
+  values are now computed into plain variables first and the two hashtables
+  are multi-line with aligned `=`. Output keys, values and file names are
+  unchanged. No rule, setting, version pin or test was relaxed.
+- `.github/workflows/demo-acceptance.yml`: each file is announced before it is
+  analyzed. A crash still terminates the step (no try/catch), and the last
+  `Analyzing ...` line names the file.
+
+## Confidence
+
+The exact crashing AST node was not reproduced by me (no shell). The two
+rewritten statements are the strongest candidate, not a proven cause. If the
+analyzer still crashes, the next suspects in the same file are the one-line
+hashtables at the `$manifest` and `$compiled` loops and the
+`foreach($x in $a | Where-Object ...)` headers; extract them into variables the
+same way. Pin a different analyzer version only if a minimal reproduction
+shows a bug that source changes cannot avoid.

+# Claude scanner-auth handoff (unbuilt, uncommitted)
+
+## Source facts (core qqq-wt-native-provider-logout, read-only)
+- QSession is fully mutable; `QContext.setQSession` aside, any code holding the session can change permissions, user, uuid, channel, security keys, variants, credentialScope in place. Nothing in core guarantees a retained wrapper still has the authority that was checked.
+- QCredentialScope has no equals; its getters return unmodifiable views; `null` set = unrestricted (distinct from empty).
+- `QSession.hasPermission` ignores credential scope, so `MobilePermissions.require(SCAN)` does not evaluate ceilings.
+
+## Change
+- (first round; see follow-up below for the current API) `VerifiedDeviceSession`: at construction stores an immutable `Authority` snapshot (userId, uuid, clientChannel, permissions, security keys, backend variants, and a `Scope` copy: credentialId, readOnly, apps/tables/processes/reports/widgets/operationIds, null preserved). `authorityUnchanged()` re-derives it and compares by value.
+- `MobileDeviceAuthorization.captureCurrent`: an existing wrapper whose authority differs from its snapshot throws `QPermissionDeniedException` (fail closed) before any other use; otherwise all existing checks run and the same wrapper is retained (no `setQSession`). First capture still wraps. Values/valuesForFrontend are deliberately excluded (non-grant data).
+- Tests (`MobileScannersTest`): `repeatedCaptureRetainsSameVerifiedSession`, `retainedSessionRejectsChangedAuthority` (device header, user, uuid/binding, permissions, approval revoke), `retainedSessionRejectsCredentialScopeAndSelectorChanges` (each ceiling set widened/nulled/narrowed, readOnly, credentialId, scope removed, channel, security key, backend variant, extra permission; each rejected with wrapper kept, then passes after restore).
+
+## Follow-up round (post-review; unbuilt, so the 35-pass result predates it)
+- `captureCurrent` now computes the expected authority once at the start (wrapper: its checked snapshot; plain session: a fresh snapshot) and calls `requireCurrent` twice: at the start, and again after ALL checks (approval, observe, binding re-read) immediately before retaining or wrapping. `requireCurrent` fails closed unless `QContext.getQSession()` is still the very same reference AND its authority equals the expected one. Core replacing the session or a host hook changing grants/ceilings during validation is rejected; first capture is not wrapped in that case.
+- Immutability assessment (core source): `QSession.clone` copies security-key lists and backend variants one level (elements shared); `QCredentialScope.clone` copies its sets (String elements). Core offers nothing deeper. So `authority()` copies collections and treats element values as safe only if they are known immutable types (String, boxed numerics, BigInteger/BigDecimal, Boolean, Character, enum, UUID, java.time Temporal). Any other element makes the snapshot carry a random marker so it never equals anything: fail closed, no custom serialization.
+- New tests: `authorityChangedDuringChecksIsNotRetained` (scoped first capture copies exact ceilings/grants/channel; mid-check ceiling widening, grant addition, session replacement on a retained wrapper; mid-check widening on first capture leaves the plain session unwrapped; a test-only POST_QUERY_RECORD hook on the device table fires during the approval read and each case asserts the hook was consumed) and `mutableSessionValuesFailClosed`. If the hook never fires, the `assertNull(hook)` lines fail loudly rather than pass vacuously.
+- Serialized-session compatibility: `VerifiedDeviceSession` declares no `serialVersionUID`, so its computed UID already changed with any prior class edit and changes again now (new fields, nested records). Evidence searched: no ObjectOutputStream/serialVersionUID use in this repo; core `StateSerialization` (Java serialization with an ObjectInputFilter allowing `com.kingsrook.*`) has no QSession reference in the `state` package. I found no source showing a VerifiedDeviceSession is persisted across deployments, so no migration is claimed or added; the wrapper is created per request. If a host persists sessions through a state provider, in-flight old wrappers would fail to deserialize after upgrade and re-authenticate. This is unverified for hosts outside this repo.
+
+## Verification fix
+- `authorityChangedDuringChecksIsNotRetained` failed with "second customizer with role postQueryRecord" because the device table already registers `MobileDeviceOnline`. The test now asserts that production customizer is registered, then replaces the map entry with `SessionMutator` (a subclass that runs the one-shot hook and then `super.apply`, i.e. the real behavior). Production code is unchanged. The `assertNull(SessionMutator.hook)` lines after each case still prove the hook ran during the checks (a hook that never fired would leave it non-null and fail).
+- Unverified: not rebuilt after this edit (no shell). `MobileBrandingTest` loopback error is environmental per root.
+
+## Security-key set semantics (RF interop fix; unbuilt)
+- `VerifiedDeviceSession.Authority.securityKeys` is now `Map<String, Set<Serializable>>`: core row security uses `List.contains`, so membership is the authority; order and repeated identical appends no longer count as change. A null list stays distinct from empty; a new value, a new key, a removed key, or a different user/scope/permission still rejects. Credential-ceiling null-vs-empty handling is unchanged. Immutable-element fail-closed rule unchanged.
+- Test `securityKeysCompareAsSets`: repeated same-value append and reorder accepted with the same wrapper; new tenant, different tenant set, new key, and a different actor rejected.
+- DONE (later, unbuilt): RF fixture `Authentication.grant(instance, session)` now ends with `CollaborationSecurity.applyToSession(instance, session)` (import `com.kingsrook.qbits.collaboration.CollaborationSecurity`), called from both `createSession` and `isSessionValid`; `integrations/record-files/README.md` documents the call order. The entry below is superseded.
+- (superseded) the RF fixture `Authentication.grant` (`integrations/record-files/.../MobileRecordFilesIntegrationTest.java` ~line 705) was not changed to call `CollaborationSecurity.applyToSession(instance, session)`. I could not find that class's package in any readable source and will not guess an import. Edit for the owner/root: in `grant`, after the existing `withSecurityKeyValue("tenant","a")`/admin permission lines and before returning, add `CollaborationSecurity.applyToSession(instance, session)` with the real import (this static method needs the `instance`, so pass it into `grant(instance, session)` from both `createSession` and `isSessionValid`). It must run in authentication, before the first Mobile capture, so no late wrapper mutation or exemption is needed. README note for the optional bridge: authentication applies `CollaborationSecurity.applyToSession` during createSession/revalidation before capture.
+
+## Limits / blockers
+- Not compiled or run (no shell). Scope test assumes a scope listing all instance tables/apps lets enroll/bind/capture work; if core denies for another reason, adjust the baseline.
+- Behavior: a legitimate in-place refresh that changes permissions now rejects until re-verified rather than being silently adopted (owner-required fail closed).
+- Credential ceilings are still not independently enforced by `captureCurrent` (SCAN uses hasPermission); they are only preserved/unchanged. Needs owner decision.
+- Out of scope, same bug: `MobilePermissions.checkPermissionsThrowing` (~line 69) still replaces the wrapper on RunProcessInput for scanner processes. Needs root coordination.

+# Scoped Echo release review — November 1, 2026
+
+An independent Claude agent reviewed the Echo implementation at4bc88a4 and the Android semantic process-choice changes retained in a2f0080. This was a read-only code review, not a new exhaustive repository or deployment security certification. It reported no confirmed high or critical finding in the reviewed happy path.
+
+The review identified one medium availability issue and two concrete low issues, corrected in this checkpoint:
+
+- Failures before a durable print intent was pinned left the same event unable to recover. An unpinned event can now retry through a single atomic pin; a missing or competing pin prevents generation. Pinned/uncertain attempts remain read-only reconciliation, never a replacement print.
+- The pin update now requires exactly one affected row. A concurrent loser cannot call the generator or mark the winning attempt as failed.
+- Accepted owner receipts are recorded before the final authority check. A late revocation still denies acknowledgment and new work, while preserving the already accepted job in the audit state. The pre-accept and pre-acknowledgment authority checks remain.
+
+Five new regressions cover pre-pin recovery, missing/competing intent, simultaneous retries, and authority loss after acceptance and during lookup. All38 example tests and all22 composed-demo tests pass with Checkstyle0 against the matched private dependency cohort. These tests use controlled output and a simulated printer; they do not prove physical output.
+
+The reviewer also noted H2-only qualification and a hypothesis about extended Code39 behavior. Other database vendors and the broader AIM/GS1/EAN/raw/decoder-mode fidelity contract are not qualified by this review. Supported-profile boundaries remain explicit; no unsupported payload is silently converted. Source publication, a qualified public Maven cohort, current primary-forge CI, physical/provider/lifecycle checks and organization signing/distribution are separate release gates.

+# GS1 duplication and mobile records
+
+Active work requested November 4, 2026. Implementation and isolated acceptance are underway; deployment and physical qualification remain separate.
+
+## First delivery: GS1-128 duplication
+
+- Preserve the original scanned payload, AIM identifier and available raw evidence.
+- Convert supported GS1 element strings to the renderer's canonical GS1 input without guessing missing separators.
+- Print a GS1-128 symbol and its human-readable interpretation underneath, preserving leading zeroes and application identifiers.
+- Verify independent decoding of the rendered output, retry behavior, permissions and refusal of ambiguous inputs.
+- Qualify the actual label/media/printer and handheld path before claiming tomorrow's workflow ready.
+
+## Native records and photos
+
+- Discover permitted tables through existing semantic metadata.
+- Browse records and open record details through existing versioned query/read operations.
+- Offer camera/gallery attachment only when Record Files authorizes that exact record.
+- Reuse the native upload implementation and committed receipt checks; cover denied records, cancellation and retries with isolated native/server E2E tests.
+
+## Remaining readiness work
+
+1. Establish the intended HTTPS host and standalone connectivity.
+2. Qualify the existing signed APK and an enrollment-preserving update path.
+3. Verify an actual MC9400 trigger and persisted record (operator action required).
+4. Adopt published, coherent owner dependencies when available; do not invent versions.
+5. Qualify native provider login, logout and account switching against the configured provider.
+6. Document and exercise database migration, backup/recovery and retention for the selected deployment.
+7. Run final server/browser/native gates on the resulting revision and reconcile release documentation.
+8. Deliver the GS1 profile above before considering broader barcode profiles.
+
+## Constraints
+
+Preserve the user's database, accounts, enrollment and printer setup. Use isolated test databases and application IDs. No offline queue or replacement screen framework. Source checks cannot establish physical scanning/printing. Do not publish artifacts or promote a stable release as part of a test run.
+
+## Verified November 4
+
+- Scanner/base-demo/Echo reactor: 135 tests passed, including GS1 raw evidence, retry identity, derived HRI, metadata discovery and read-only permission regressions. Checkstyle passed.
+- Final composed cohort: 188 tests passed (scanner 53, base demo 8, Record Files 18, Echo 74, Echo demo 35), with Checkstyle, using the previously qualified owner dependency versions in an isolated copy. No POM publication coordinates were changed.
+- Android core/mobileapp/host unit tests, lint and debug/E2E APK builds passed; eight test-runner guard tests passed.
+- Disposable MC9400 native Echo acceptance passed with synthetic Code128, QR and GS1-128 events, one job per event, rotation/recreation, run cancellation and saved-record browsing. All requests matched the published semantic API. Printing was simulated; this does not qualify the physical trigger.
+- Disposable MC9400 record-details acceptance saved synthetic camera and gallery photos to the selected record through the real Record Files APIs. Pending-photo rotation, navigation blocking and remote-logout cleanup passed. The existing process-based photo flow also passed the same camera/gallery and lifecycle regression.
+- Actual renderer output independently decoded for synthetic GTIN/date/serial and separator-bearing batch/serial examples on 4-by-1-inch, 300-dpi media; HRI matched and did not overlap the symbol.
+
+## Deployment and migration gate
+
+Before updating the maintained demo, stop its owning process cleanly and back up the closed database, attachment files and configuration together. Preserve accounts, device enrollment, printer settings and template revisions. Apply the additive nullable `rendererValue` and `humanReadable` columns in `echo-h2.sql`; existing scans keep their original values and are not backfilled or reprinted. Verify the backup can be restored into an isolated directory and start only that restored copy for the recovery check.
+
+Publish a separately named GS1 document using `EchoTemplatePublisher.publishGs1` for the printer's reported media profile. Existing plain documents remain valid for their original profiles. Use the matching GS1 document for the sample label, print one copy, then scan that output and compare exact GS1 data and visible HRI. Do not declare physical acceptance from a synthetic broadcast or renderer-only result. Printer/media confirmation, deployment authorization, HTTPS configuration and the remaining readiness gates above are outstanding.
+## Forge source publication
+
+Server source commit `1874c64` merged through PR 15 as `f9b0eb2` after Gitea checks 4318 and 4319 succeeded. Signed tag `echo-gs1-source-20261104` pins that exact merged tree. The Gitea prerelease includes a source archive, checksum and verification receipt. Forge must include `examples/echo` explicitly; publishing the root scanner JAR alone does not include GS1 duplication. This is a source integration release, not an Echo Maven or APK release. No Forge or handheld deployment was performed.

-Before upgrading an existing demo database, stop its JVM gracefully and back up the closed `demo/data` directory together with its protected credential file. The shared H2 schema begins with `SET TIME ZONE 'UTC'` before converting legacy `TIMESTAMP WITH TIME ZONE` columns to the current UTC `TIMESTAMP` representation. This protects both the demo initializer and hosts executing the supplied schema directly. It preserves the original instants independently of the workstation time zone; rerunning initialization preserves existing accounts, passwords, device approval and scans. Do not copy over an open H2 database or use an account reset as an upgrade step. The schema leaves its migration connection in UTC; hosts should use a dedicated migration connection or restore their desired connection zone after the entire script completes.
+First startup creates random passwords for the `admin` and `scanner` accounts. They are protected with Windows DPAPI under `%LOCALAPPDATA%/QRunIO/MobileScannersDemo/credentials.clixml`, readable only by the same Windows user, and are never written to the repository or printed. The launcher never changes existing passwords. If a database exists without its credential file, it refuses to start rather than reset accounts.

-Use the matching Android build with the [mobile-scanners semantic API extension](UI-API.md). Public discovery is at `/qqq/v1/version`; the extension's connectivity endpoint is `/qqq/v1/qbit/mobile-scanners/status`.

-## Emulator walkthrough
+## Connect a device or emulator

-Follow the Android repository's [emulator guide](https://github.com/QRun-IO/qqq-android/blob/feature/mobile-scanner-host/docs/EMULATOR.md) to start a virtual device and install the debug APK. Forward its port to the host:
+Install the matching debug build of the [Android scanner host](https://git.kof22.com/QRun-IO/qqq-android) (the `scanner-host` module; its `docs/EMULATOR.md` covers the emulator). Always pick the target explicitly when more than one device is attached. USB or paired wireless ADB both work; do not put device serials or addresses in notes or commits.

 ```powershell
-adb reverse tcp:8080 tcp:8080
+adb devices -l
+$serial = '<serial or address from adb devices>'
+adb -s $serial install -r <path to scanner-host-debug.apk>
+adb -s $serial reverse tcp:8080 tcp:<host port>
 ```

-If the host server uses `-Port 18080`, use `adb reverse tcp:8080 tcp:18080` instead; the Android server URL still uses port 8080.
+`install -r` updates the app without clearing its login or enrollment. Use the host port the server actually listens on (8080, the `-Port` value, or the Echo launcher's port). The app URL on the device stays `http://127.0.0.1:8080` because the forward maps device port 8080 to the host port. The debug build permits HTTP only for this local use; deployed builds require HTTPS.

-1. Open **QQQ Mobile** on the emulator and use server `http://127.0.0.1:8080`.
-2. Sign in as `scanner` and enroll the device. It starts pending approval.
-3. In the browser as `admin`, open **Mobile Scanner Administration → Mobile Devices**, open the device record, and choose **Actions → Approve Device**. Review the selected device, continue, and check the success result. For several devices, select their rows in the device list and run the same action from the bulk menu. The standalone sidebar process also accepts device IDs.
-4. Refresh approval on Android, open **Scan Capture**, type a barcode such as `000123456789`, and submit it.
+## Walkthrough: enroll, approve, scan, revoke
+

-The emulator exercises native screens, login, approval, manual capture and persistence. Verify the physical trigger, DataWedge delivery and barcode decoding on the Zebra TC22 using [the hardware checklist](TC22-ACCEPTANCE.md).
+Approval and revocation accept checked rows, select-all matching rows and first-N selections, up to 100 devices per run. The confirmation fixes the selected IDs for that run, so a device that enrolls afterwards is not included; larger selections fail explicitly, and nothing changes until you continue past confirmation.

-Approval and revocation support checked rows, select-all matching rows, and first-N selections, up to 100 devices per run.

No approval changes occur until you continue past confirmation.

+## Full Echo demo
+
+Follow the [Echo demo README](../examples/echo/demo/README.md) for build, environment variables (set in the environment, never on the command line), accounts and permissions, and operator order. Use the trusted-local launcher for a developer machine and the production `EchoDemo` only with the owner's qualified renderer sandbox. The Android flow is the same as above, then open **Echo**, choose the printer, paper size, document and optional copies, and scan.
+
+## Upgrading an existing demo database
+
+Stop its JVM gracefully and back up the closed `demo/data` directory together with its protected credential file. The shared H2 schema begins with `SET TIME ZONE 'UTC'` before converting legacy `TIMESTAMP WITH TIME ZONE` columns to the current UTC `TIMESTAMP`, preserving original instants regardless of the workstation time zone. Re-running initialization preserves accounts, passwords, device approval and scans. Do not copy over an open H2 database, and do not use an account reset as an upgrade step. The schema leaves its migration connection in UTC, so hosts should use a dedicated migration connection or restore their own zone afterwards.
+
+Use the matching Android build with the [mobile-scanners semantic API extension](UI-API.md). Public discovery is at `/qqq/v1/version`; the connectivity endpoint is `/qqq/v1/qbit/mobile-scanners/status`. Upgrade the server and the app together: the former standalone mobile routes are gone.

+# Mobile browsing test data

+| Test Orders | 1,000 | 39 fields across Order overview, Customer, Shipping, Amounts, Warehouse, and Notes and audit |
+| Order Items | 12,000 | 12 related items per order, grouped item and handling fields |
+| Order History | 3,000 | Three related history entries per order |
+
+Values exercise dates, timestamps, numbers, decimals, booleans, leading zeros, Unicode, multiline notes, long descriptions and empty optional fields. All customer information is fictional.
+
+Search or filter the table, open an order, and use Details, Items, History or Photos. Details groups collapse and can be selected directly. Table pages contain 25 records; related tabs contain 10 records per page. Back preserves the table page and search/filter state.
+
+Use **Actions → Add photo → Take photo / Choose photo** to attach an image to the displayed record. Photos lists saved attachments, including those awaiting server review; available images have thumbnails and previews. Normal Record Files permissions, quarantine and upload lifecycle still apply.
+
+The native preview uses standard QQQ metadata sections and direct association joins through the existing semantic query/get API. It supports read-only browsing; arbitrary widgets, nested editing and unsupported relationship definitions are not added by this fixture.
+
+`MobileTestData` belongs only to `examples/echo/demo`. Startup adds missing H2 tables and missing synthetic rows without replacing existing rows or attachments. The scanner account can read these tables and attach photos; raw table edits remain refused. The basic Scan Capture demo does not install this dataset.

+
+1. Preserve table page, scroll, search and filter state across record navigation and recreation.
+2. Keep record identity visible; add Details, related-record and Photos navigation, collapsible field groups, compact summaries and formatted values.
+3. Put capture/selection behind Actions → Add photo; retain pending-upload guards. Browse saved attachments with lifecycle status and authorized previews.
+4. Use standard semantic metadata, query/count/process and owner attachment/download APIs. Preserve existing permissions and quarantine.
+5. Verify unit/build/lint, isolated real native flows, and actual TC22 layout; update the same app/server with preserved data.

+# Single-instance deployment and recovery
+
+Written 2026-11-05 from the static final review of source base `a9eae04` (see [review reconciliation](REVIEW-RECONCILIATION-2026-11-05.md)). The procedure below is for the host/operator in a real incident. The only executed evidence is the automated [isolated local-demo recovery acceptance](#isolated-local-demo-recovery-acceptance-automated-passed), which covers the demo's stopped H2 database plus object snapshot and restore. No production storage, enterprise object-store or high-availability deployment is supported or qualified, and those are not tasks of this scanner release. The supported model is one server process per database.
+
+## Topology
+
+- Run exactly **one server JVM per database**, with no overlap during an upgrade (stop the old process before starting the new one). Revocation and capture-commit exclusion use a per-JVM monitor, screen-mirror frames are held in memory only, and Echo job admission relies on a row lock in that one database.
+- H2 must be used single-process. Do not point two servers at one database.
+- The host owns HTTPS and the identity provider; the loopback HTTP demo is not a deployment ([production readiness](PRODUCTION-READINESS.md)).
+
+## Backup and restore
+
+- Take one **consistent snapshot of the database and any file storage together** (same moment, or with the server stopped). A database restored without its matching files, or the reverse, leaves dangling references.
+- Treat bindings and backups as **sensitive**. `mobileSessionBinding.coreSessionUuid` is stored in plaintext at rest (reads are blocked by the application, not by the backup). Anyone holding a backup holds live session identifiers until they expire or end. Backups also contain barcode payloads and last-known device location.
+- After any restore, before reopening to users:
+  1. Stop all server processes, then restore the database and files from the same snapshot. Nothing can be done through the application while every server is stopped, so steps 2 and 3 need a running server.
+  2. **Restart in controlled, admin-only access** (for example, reachable only by administrators, with scanner clients and other users kept off the network path) and keep it that way through steps 3 to 6. Do not reopen to users first: a device revoked after the snapshot may be approved again and a session ended after it may be active again.
+  3. **Re-audit device approvals.** A restore reverts revocations, approvals and enrollments made after the snapshot, so a device revoked later may be approved again. Review every device and re-revoke as needed.
+  4. **End or reconcile active sessions.** Tombstones written after the snapshot are lost. With the server running in that controlled state, apply the End Session process to the restored sessions so cleanup runs against the restored state, and check the cleanup status below.
+  5. Devices enrolled after the snapshot no longer exist and must re-enroll.
+  6. **Echo:** jobs accepted after the snapshot may be absent from the database although a print was already queued. Manually reconcile the physical or Printing queue against the restored jobs **before authorizing any retry**, and retry only what that comparison shows was not printed. This is a manual check; there is **no exactly-once physical print guarantee**, and a retry can still produce a duplicate or a missing print if the queue or printer state is unknown.
+  7. Reopen to users only after the above are done.
+
+### Isolated local-demo recovery acceptance (automated, passed)
+
+`EchoDemoAcceptanceTest.restoredSnapshotKeepsScanAndRetainedFileAndRevertedApprovalStateIsReaudited` (Echo composed demo) exercises this procedure on private temporary directories only.
+
+**Verification (2026-11-05):** the combined five-module `verify` on the merged source (`develop` `9e8685f` plus the storage fixes) passed with qualified private owner dependencies: 196 tests (root 53, demo 8, Record Files 22, Echo 74, Echo demo 39), 0 failures, 0 errors, 0 skips, and zero Checkstyle violations in every module. The qualified owner inputs are private, so this is not public-dependency qualification.
+
+The case restores H2 scan rows, the exact leading-zero value and symbology, and the Record Files owner's own `RecordFilesTables.FILE` row. It asserts that row's exact table, record and attachment relationship and the SHA-256 of the object bytes. It shows that a revocation and session end made after the snapshot are reverted by the restore, then reapplies the normal Revoke and End Session processes and shows that a valid in-flight run and a new initialization are denied. No physical printer, service or demo data was changed.
+
+Flow: it enrolls and approves a synthetic device, scans over real HTTP, and lets the real Record Files service retain the generated original in the demo local-file adapter. With the servers stopped and H2 shut down, it copies the database and object directory together, makes later changes (a second scan and file, a revocation and an ended session), restores only those two temporary directories and reads them without the application. It then restarts on a new ephemeral loopback port and applies the existing Revoke and End Session processes.
+
+What this is **not**: it covers the local demo's H2 database and local files only, using private coherent fixture inputs. It is not published-cohort qualification (that is repeated when the final public dependencies are adopted), and enterprise object-store and high-availability recovery are unsupported and unqualified. In a real incident the full procedure above still requires an operator-owned audit of approvals, sessions and the print queue before a restored service returns to users.
+
+Storage regressions in `PrivateObjectFilesTest` (part of the Echo demo's 39 tests): `concurrentSameKeyWritersLeaveOneWinnersBytesAndMetadata` (concurrent same-key writers leave one winner's bytes and metadata), `dotBucketsAreRefusedAndValidBucketsStillWork` (`.` and `..` buckets refused), plus `existingObjectIsNeverReplaced` and `keysCannotTraverseOrAlias`.
+
+Limits: the file store is the single-host demo adapter and the database is the demo's H2 file, so this does not qualify production storage, an object store, encryption or high availability. Other database backends are not supported or tested here. The renderer is controlled and the printer is a database fixture; no job is physically printed and no normal demo data is changed. The file check reads the Record Files rows and object bytes directly, not through a product service.
+
+## Session cleanup status
+
+Ending a session (`MobileSessionService`) first persists the ended state with `authCleanupStatus = PENDING`. Cleanup then sets `REQUESTED` (with `authCleanupAt`) **before** calling the logout executor and removing the stored core session. If that call throws a `QException`, the status becomes `RETRY_NEEDED`. So `REQUESTED` means cleanup was attempted and no failure was reported; it is not independent proof that the provider session is gone. Cleanup is skipped when a binding does not exist, and for a single end inside an open transaction; a status left at `PENDING` also needs a retry. The bulk End Session process commits all tombstones first and runs cleanup afterwards.
+
+To retry: find sessions with `authCleanupStatus` of `RETRY_NEEDED` or `PENDING` (admin view of the session table), then run End Session again for them. Ending an already ended session does not change its end time and reruns cleanup when a binding exists. Confirm the status reaches `REQUESTED`. There is no automatic monitor in this repository; the operator must check for these statuses.
+
+## Retention
+
+Scans, sessions, bindings and Echo scans are **kept indefinitely** by default. Table deletes are blocked by permissions and foreign keys tie history to devices. Barcode payloads and last-known location are retained, so a different retention period is a host-owned policy, not a feature of this release: any purge is a host DBA procedure, taken with a snapshot first and respecting the foreign keys. Audit is current-state only; revoking overwrites the previous approver and time.
+
+## Database migration beyond H2
+
+The supplied, tested scripts are H2: `src/main/resources/db/mobile-scanners-h2.sql` and the Echo `echo-h2.sql`. Other backends are unsupported and untested here; a host that uses one **owns the equivalent migration**; do not assume `ADD COLUMN IF NOT EXISTS` or the column types. Additive columns that older databases need before running current servers: on `mobileScan`, nullable `aimIdentifier` (`VARCHAR(3)`) and `rawDataBase64`; on Echo, nullable `echo_scan.aimIdentifier`, `rendererValue` and `humanReadable`, and **`echo_run.copies`, which is `INT NOT NULL DEFAULT 1`** (existing runs keep one copy), so it is not nullable and the equivalent migration must supply the default. Echo also has nullable template columns (`templateId`, `templateRevisionId`) in `echo-h2.sql`. Test the migration on a copy, and snapshot first.
+
+## Demo-only file adapters
+
+`LocalFilesystemAttachmentStorage` and `LocalStagingChunkStorage` (Echo demo) are single-host local-file adapters for the demo. They are not production storage; photo and record-file storage for a deployment is not qualified here. `ECHO_RELEASE_GENERATED_FILES=true` turns off generated-file quarantine and exists for the demo only; leave it off unless every producer permitted to keep generated output is trusted ([Echo demo README](../examples/echo/demo/README.md)).

Client strict compilation and163 JVM tests pass; final TC22 native acceptance is running and the Query artwork density warning is being corrected before installation. About includes bundled Query artwork and the exact public Dogfooding/Query links.

-Actual Authentik desktop acceptance now passes real negative nonce rejection, A login, explicit company logout, old-cookie rejection, fresh B credentials and B principal in the same retained browser context, followed by B local logout/rejection. HTTPS verification remained enabled with profile-only fixture trust. The owned provider required its documented company invalidation flow; no global flow or default client sign-out policy changed. This closes the earlier desktop A-to-B handoff failure for the qualified API1.10 fixture, not the actual Android external-browser callback gate. The normal server remains API1.9/mobile1.1 and operator data is preserved.

The subsequent optional provider-logout working patch passes148 JVM tests, lint and debug build; its native tests compile but have not run. The completed-logout/enabled-action guard retains fresh-login/new-session assertions. Portrait default preserves explicit saved choices. | Physical operator navigation, lifecycle, ownership, outage/retry and leave/cancel walkthrough. Any later executable source needs its own verification. |
-| Trusted scanner ingress and hardware | Ordinary-UID/distinct-signer rejection of eight forged scans plus manual positive control; actual EMDK Code128 source/model/event proof: eight deliberate events on prior F3AF APK and one on the installed portrait-default C891 APK. Historical DataWedge evidence is separately retained. | Current leading-zero QR, repeated-intent/lifecycle/ownership matrix, connection failure and uncertain receipt/retry/leave acceptance.

-
- Server semantic baseline: `7dd02b8874882ca2edcdcd89109b3dee6b4b0c88`, with all hosted checks passing. Documentation checkpoint: `a49724384f569a4b4b66ce2cd4aa69332ee1e0e8`.
- Android semantic baseline: `6574ec4991dbb859b60c3a0be462af96918aee32`; hosted JVM/lint/APK, CodeQL and CircleCI checks passed, but both hosted native E2E jobs failed at compatible login before any credential request reached the server. Login/form reachability fixes are under verification; this baseline is not fully green.
- Active implementation: [device/session history, live activity, actual app screen viewing, session termination, identity/presence/location and Record Files integration](DEVICE-SESSIONS.md).
- Final audit scope: both complete repositories, including shared Android core/mobileapp libraries, scanner host, qbit, demo, build/release configuration, tests and documentation. Exclude local secrets and operator data from published evidence.

-## Verified baseline evidence
+## Open gates

-October 31 working-source evidence: 37 root tests, two real HTTP acceptance tests and all 15 browser E2E cases pass. Browser cases include single/selected-bulk/full-query session end, cancellation, live image/clear, device profile edits, location timestamps and online expiry/filtering. The full browser run completed in 59.4 seconds after correcting file-H2 connection lifetime. A subsequent virtual-online projection fix passes the 37-test suite; its combined native acceptance remains pending. Android's intermediate 76 JVM tests and zero-error/zero-warning lint pass; shared native and real-server session tests remain in progress. These are local intermediate results, not a frozen release or fresh hosted qualification.
+The maintained server and existing TC22 app now run the GS1, rich test-data and record UX changes. Actions → Add photo, grouped/related records, search/filter/Back state and the saved-photo gallery are implemented and verified by isolated native acceptance plus an actual TC22 visual pass. Existing data and enrollment were preserved. See [current evidence](history/MOBILE-UX-2026-11-05.md). This supersedes the earlier undeployed status; physical GS1 print/rescan and signed-build production deployment remain open. The user authorized the final release, signing and publication for this bounded goal; Android PR 15 (`c782aaaaba3f62422232436a9000af9d4b38fc82`) merged after all CI.

-Server: 23 root tests plus the real HTTP lifecycle scenario and six packaged-frontend browser E2E scenarios. Android: 53 JVM tests, six shared native UI tests, lint with zero errors/six warnings, debug/E2E APK builds, and six semantic native scenarios across focused runs. The final admin scenario passed in 255.917 seconds; 31 of 31 requests matched 13 published operations, including cancellation. These results are baseline evidence and must not be represented as verification of later session/mirroring changes.
-
-Physical TC22 (Android 14, DataWedge 13.0.325, app 0.1.0): installed with existing state preserved, signed in and approved through the actual device-record process. A dedicated DataWedge profile uses barcode input, explicit broadcast delivery and package/signature verification, with keyboard output disabled. Two deliberate Code128 trigger scans produced two records. One QR trigger scan preserved `001234567890`; backend records confirmed symbology, source, user/device/app/process and timestamps. Outage/retry and remote-session controls remain to be tested on the completed feature.

-## Review findings
-
-The initial full-source architecture/maintainability review covered Android `6574ec4` and server `7dd02b8`; it does not cover the later session/device features. Findings are being remediated, with final independent review still required:
-
-| Finding | Remediation owner / evidence pending |
+| Gate | What is still required |
 | --- | --- |
-| A1: scan retry cleared on an incomplete receipt | Android host: require matching acknowledgement ID, `scanSaved=true` and nonblank scan ID. |
-| A2: invalid scanner length metadata silently defaulted/truncated | Android host: reject invalid or out-of-range metadata. |
-| A3: legacy INPUT_FIELD bypassed typed field semantics and interpreted input as action code | Shared client: typed field handling and explicit action capability. |
-| A4: ordinary asynchronous status failures lacked a safe retry | Shared client: retry status GET without replaying submission. |
-| A5: cancellation during initialization could leave a late process orphaned | Shared client: retain cancellation intent and cancel a returned process ID. |
-| A6: login/forms could place actions outside the viewport or behind the keyboard | Shared client: scrolling/IME handling and constrained-viewport native tests. Hosted failure cause remains unproven until the regression evidence is complete. |
-| A7: explicit null displayed a default while submitting null | Shared client: distinguish absent keys from explicit null consistently. |
-| A8: business JSON collided with class-based serialization envelopes | Shared client: ordinary JSON values without class loading. |
-| A9: multi-record mutations and enrollment could persist partially | Server: transactions for credential/device and session/binding pairs and bulk state changes; provider logout after durable tombstones with explicit cleanup outcome. |
-| A10: media ownership/disposal could leak resources | Shared client: sound/image lifecycle ownership. |
-| A11: navigation title/state and native back stack could drift | Android host: derive navigation state from the active NavController. |
+| Public dependency cohort | Public, coherent Generation/bridges/Record Files/Scripting artifacts from their owner; adoption of the Core/Collaboration/Next UI foundations when released. Today these are qualified owner inputs. |
+| Release | Retest the full gate when the final public dependency cohort is adopted, with a reviewed release manifest; Maven publication stays disabled until then. Redesign of the shared CI pipeline is outside this scope. |
+| Signing and distribution | Done: QRun key with backup, signed Android 1.0.1 (code 3) built from the merged PR 15 source tree and installed in place on an MC9400 (installed bytes match; login/enrollment preserved; Scan Capture reopened; HTTPS connected). Open: MC9400 physical trigger scan, public dependencies and final distribution. No signing CI. |
+| Deployment | HTTPS and the host's identity provider. Single-instance procedure, recovery and default-indefinite, host-owned retention guidance is in [operations](OPERATIONS.md); isolated local-demo recovery acceptance has passed. Enterprise object-store/HA and non-H2 databases are unsupported and unqualified options, not release tasks. The HTTP loopback demo is not a production deployment. |
+| Provider authentication | Native OAuth2 requires UI API 1.10 native-session and nonce-validation support on the server (verified in the Android source). Still open: native Authentik login, logout and account switching on a handheld. No such handheld test is claimed. |
+| Further device qualification | MC9400 physical trigger check and MDM-applied managed configuration remain unverified. Company profile/wallpaper is separate tracked scope, not a blocker for this release goal. The TC22 camera, GPS and screen-viewing checks are covered by the accepted operator group report; no separate per-case evidence is claimed or required again for that demo. |
+| Barcode fidelity | Echo's supported profiles are documented ([limits](../examples/echo/README.md#fidelity-and-limits)); The committed source supports bounded GS1-128; physical print/rescan remains open. Other GS1, ECI, structured and binary profiles remain refused. No universal barcode-reproduction claim. |
+| Final reviews | Reconcile the dated security, architecture and standards reports to the final revision; they are scoped historical reviews, not a fresh exhaustive scan. A dated static review of base `a9eae04`, its supplement and its scope and limits are in [review reconciliation](REVIEW-RECONCILIATION-2026-11-05.md); it is not an audit rating. |

-The completed TC22 session scenario delivered and decoded real application JPEG pixels, cleared background frames, renewed viewing on resume, honored operator Stop viewing, ended the session remotely and accepted a fresh login. Android packaging now verifies 130 notice entries, nine license texts and eight native binary hashes in each host variant. The full server static scan is complete; Android review, external core logging remediation/adoption, production signing/update path, supported database migration and final hosted checks remain required before 1.0.

+# Final review reconciliation, 2026-11-05
+
+**Source base:** `a9eae04` (merge of PR 17, record-files publication metadata), branch `docs/release-readiness-reconciliation`. Present status is in [session state](SESSION-STATE.md).
+
+This records what one static review covered. It is not an audit rating and not a release or production claim.
+
+## Scope and limits
+
+- Method: a source and test **read** of the server and Echo at the base above. Nothing was built, run or deployed for the review itself.
+- Validation of the resulting patch: on the working tree, root `./mvnw verify install` passed 53 tests with zero errors, failures or skips and 0 Checkstyle violations, and the frozen 1.5.0 YAML's SHA-256 equals the runtime YAML. Base demo verification also passed all 8 HTTP/presence/migration tests, zero failures/errors/skips and 0 Checkstyle violations (61 tests total). Earlier cohort counts in [session state](SESSION-STATE.md) remain historical and were not rerun on final public inputs; no whole-cohort or public-release verification is claimed.
+- Found no actionable source blocker among the traced paths: admin single/bulk processes, device approval and revocation, session end, scan idempotency, session mirroring, Echo copies and retry, and the optional file-integration guard.
+- Not verifiable here: Android-source items (A3, A5, A6, A8, A10, A11), which rely on the Android repository's own closure report.
+- Not read in that pass: the GS1 renderer-side classes (`EchoGs1`, `EchoTemplates`, `EchoTemplatePublisher`, `EchoOwnerAdapters`), `EchoDemoAuthentication`, `LocalStagingChunkStorage`, `PrivateObjectFiles`, and the Record Files and Echo test sources.
+- Not covered: physical output (copies, GS1 print and rescan), the owner Generation/Printing behavior, browser E2E re-run, MC9400, HTTPS and the identity provider. These remain pending as listed in [production readiness](PRODUCTION-READINESS.md). The three earlier dated reviews predate GS1, copies, photo capture and the 1.5 raw metadata.
+
+## Actions taken from the review
+
+- Status documents reconciled to the committed GS1 source and PR 17.
+- [Operations and recovery](OPERATIONS.md) added; it is a procedure, not an executed drill.
+- A frozen 1.5.0 OpenAPI baseline added to the contract test; the existing baselines and assertions remain. No runtime or contract change.
+- `UI-API.md` operation table now lists all seven operations; root `pom.xml` url, scm and issue tracker point at Gitea.
+- Deferred: the screen-upload 409 and every other operation's 409 share the generic text "Installation already enrolled" in `MobileJsonSpec`. Correcting it is a contract text change needing a patch version bump and regenerated YAML, so it is not done here.
+
+## Supplement: findings checked after the review
+
+Scope: the four findings raised after the static review. This is not an audit rating or a score.
+
+- **F1, concurrent metadata overwrite:** fixed in `PrivateObjectFiles` and regression-tested by `PrivateObjectFilesTest.lateSecondWriterIsRefusedAndFirstWritersBytesAndMetadataRemain` (also `existingObjectIsNeverReplaced`). The controlled interleaving reproduced mismatched metadata on the old implementation; all eight storage tests then passed with the fix.
+- **F2, dot bucket traversal:** fixed and regression-tested by `PrivateObjectFilesTest.dotBucketsAreRefusedAndValidBucketsStillWork` (also `keysCannotTraverseOrAlias`).
+- **F3, ZPL command injection:** disproven at source. In the owner Generation renderer, `ZplRenderer.java` lines 326-331 encode every UTF-8 byte under `^FH`. `RendererTest.typedZplEscapesCommandsAndEmitsRasterBarcodes` covers `^XA`, `~JA` and underscore input. That source is owner-held; the exact published artifacts are still pending qualification.
+- **F4, label clipping:** the assumption is guarded by renderer placement bounds, which refuse overwide text. No universal media-fidelity claim is made.
+
+The fixes were verified by the 2026-11-05 combined five-module `verify` (196 tests, zero failures, errors and skips, zero Checkstyle violations) on qualified private owner dependencies, not on published artifacts. Pending: owner artifact qualification, physical output and any enterprise object-store or high-availability recovery (unsupported, not tasks of this release).
+
+## Inherited guardrail heuristics (visible, not disabled)
+
+Two generic guardrail reports are heuristic mismatches, not missing behavior. They stay visible as existing signals; no check was disabled and no test marker was added to satisfy them.
+
+- **Cross-QBit references.** Root `src` imports no other QBit's package and its POM depends only on core, Javalin and test libraries. The references are in the separate Echo and Record Files modules, where they are the purpose. Any allowlist belongs at the guardrail, not here.
+- **OpenAPI and test markers.** The contract is covered by `MobileScannersApiContractTest` (generated against committed YAML and the 1.0.0, 1.1.0, 1.4.0 and 1.5.0 baselines, exact path set and schemas) and real discovery in `MobileHttpAcceptanceTest`. A generic string-marker scan cannot see this.

-## November 1 typed scan context implementation
+Current as of **2026-11-05**. Open work is in [TODO](TODO.md), release gates in [production readiness](PRODUCTION-READINESS.md), and prior evidence in [history](history/README.md).

-Extension 1.3 defines accepted `scanContext` for backend actions, preserving exact symbology and server-derived attribution. Legacy omissions are explicit UNKNOWN/MANUAL; event inputs are consumed, changed retry types/apps/processes are rejected, and pre-context state requires reopening the process. The default scanner loop remains while appended host steps can consume context. Qualified private API 1.10 verification passes 44 root, seven real-HTTP demo and 18 optional integration tests with normal Checkstyle; canonical contract generation passes two additional tests and preserves both release baselines. The source cohort is `qqq-server-typed-context-843fa0ee69b34535b1890cf7347492ee`; no normal runtime adoption is implied.
+## Source and publication

-## Echo implementation scope
+GS1-128 duplication, including barcode and printed HRI, is merged through [PR 15](https://git.kof22.com/QRun-IO/qbit-mobile-scanners/pulls/15), commit `f9b0eb2`, and included in the [Forge source prerelease](https://git.kof22.com/QRun-IO/qbit-mobile-scanners/releases/tag/echo-gs1-source-20261104). This is source publication, not a published Echo Maven dependency. PRs 17 and 18 add publication metadata, the frozen contract baseline and recovery guidance; those changes are retained in this feature branch.

-User requested example QQQ application Echo: first select printer and paper/label size, then continuously scan → render the same value/symbology → print until leaving. User chose one in-flight job and delegated first real printer/media choice to the printing master. Team implements the optional examples/echo host, ordinary semantic QQQ process metadata and server per-scan context; no new Android screen engine, barcode encoder, attachment framework or print queue.
+The [rich demo fixture](MOBILE-TEST-DATA.md) and [record UX improvements](history/MOBILE-UX-2026-11-05.md) are implemented. Native browsing, record Actions and photo presentation belong to the companion Android repository. The user authorized the final release, signing and publication for this bounded goal. Android [PR 15](https://git.kof22.com/QRun-IO/qqq-android/pulls/15) merged as `c782aaaaba3f62422232436a9000af9d4b38fc82` after all CI. Maven publication switches stay disabled until the public dependency cohort is adopted.

-Owner coordination requests are posted in our shared mailbox. Source discovery found missing authorized media discovery/job options, worker barcode fit-to-stock, least-privilege printing submission and an immutable retained-print adapter handoff. These are concrete integration gates, not permission to change the other masters' source or live printer/service. Implementation and isolated tests can proceed while owners respond; no physical print or final working Echo claim yet.

-## November 1 standards implementation and API 1.10 qualification
+## Local runtime

-Copyright/SPDX, member layout and optional PowerShell tooling fixes are applied. Unexpected server failures now produce fixed structured diagnostics without private values. The attachment test fixture closes its metadata-before-stream ownership gap. Fresh Checkstyle/compilation, 39 root tests and six real HTTP tests pass against the qualified private API1.10 cohort; optional integration verification is tracked in the standards review. These are source gates, not a normal-server deployment.
+The maintained composed Echo server and **existing TC22 app** were updated in place on November 5. Database and attachment objects were backed up first; accounts, enrollment, app data and printer configuration were preserved. Live reads verified 1,000 test orders, 12,000 items and 3,000 history entries; orders have 39 fields, six groups and two associations.

-Core native API1.10 is signed and published as e1e45b29f in draft PR1369. Its real Authentik fixture is upgraded and actual retained-browser account switching is under test. Android1127 is published; the installed normal APK is the diagnostics/location3fee build, preserving sign-in and data. Prior installed1c Code128, leading-zero QR and menu/reopen were physically confirmed. Default-on location, existing fine/coarse grants and system location are verified; an actual GPS fix remains open. Historical entries below retain their original scope. See [standards review](CODING-STANDARDS-REVIEW-2026-11-01.md).
+Use **Test Data → Test Orders → a record → Actions → Add photo**. Details, Items, History and Photos tabs provide direct access. Search/filter/count and Back preserve table context. Approved photos have thumbnails/previews; quarantined uploads remain listed as awaiting review. Ordinary read/attach permissions still apply.

-## November 1 provider logout implementation in progress
-
-Core32 passes all ten hosted checks, including corrected1000-test sample acceptance; Android8d8 passes all eleven checks. The final coherent core32/scanner1a3 cohort passes39 scanner/six demo/18 Record Files/15 browser cases and is recorded in the published qualification document.
-
-Real Authentik now passes a desktop-browser PKCE callback through the native-session exchange contract, principal A, QQQ logout and old-cookie rejection. This does not establish Android external-browser acceptance. A subsequent login with provider SSO retained silently reused A despite prompt=login. The pinned provider also ignores max_age=0. This is an open operator-handoff issue, not a passed two-operator test. Optional standard RP-initiated logout is being implemented in core branch feature/mobile-native-provider-logout (based on core32) and the Android client, with explicit API1.10 capability, encrypted session-bound hint storage, local logout independent of provider failures, and a separately correlated AppAuth end-session attempt. The user policy choice (automatic company sign-out versus retained SSO with account confirmation/Switch account) remains pending; default sign-out behavior has not changed.
-
-The optional Android provider-logout working patch passes148 JVM tests, lint and debug build; native cases compile but have not run. The first isolated core package failed at an UpdateOutput API mismatch before tests. Independent review also found the optional hint gate must reject alternate in-process/code-state authentication sources; corrections and an HTTP regression are in progress. Initial failed candidate evidence is preserved.
-
-The isolated localhost-CA E2E APK built from signed Android8d8 passes63 unit cases/zero lint errors and packaged CA/callback/signature inspection. It is not installed; no device trust changed. Normal TC22 remains portrait C891 and its API1.9/mobile1.1 server remains untouched. Current QR, camera/gallery, projection, GPS and failure/navigation operator acceptance remain open. Files-owner immutable handoff/default adoption and final signing/distribution remain separate.

-Published server1041693 retains its qualified source-pinned API1.9/mobile1.2 server/demo/browser/provenance evidence. Android portrait-default7de passes all eleven hosted checks; QR documentation2e0fd962 does not establish physical QR acceptance. The normal runtime remains coreecf/serverb14 API1.9/mobile1.1 on57832, with normal portrait-default C891 development APK installed preserving signer/data. Trusted EMDK Code128 evidence comprises eight priorF3AF events and oneC891 event; QR, lifecycle/ownership and failure/retry/leave operator paths remain pending. Whole-device1.2 is qualified source, not installed normal-server behavior.
-
-Filesystem portability passes142 discovered/138 passed/four existing skips, including the corrected invalid-reference exception contract; its metadata symlink-parent and NUL-reference findings are independently closed. The final coherent core32/scanner1a3 cohort passes78 consumer cases, including18 Record Files cases, with no separate filesystem override. Matching files-owner immutable/default adoption remains open. Actual Authentik flow remains pending; strict proxy TLS now works, while provider configuration returned a validation error under diagnosis; physical projection, camera/gallery and GPS acceptance remain open. Signing/distribution stays owner-deferred until the final step. [PRODUCTION-READINESS.md](PRODUCTION-READINESS.md) is the current matrix; older entries below retain historical scope and are superseded where their then-open state has changed.

-six demo HTTP, 18 Record Files and 15 real-browser process tests), with coherent
-backend versions, 214 optional runtime JARs and zero duplicate QQQ/QBit classes.
-Core verification combines the prior full reactor gate, the corrected filesystem

-The files-owner matching immutable handoff, optional default adoption and actual
-camera/gallery acceptance remain open. This cohort did not change the normal
-runtime, device or historical optional default.
-
-## October 31 current checkpoint
-
-The normal local demo is now running the qualified `ecf0f550`/`b14d925` API1.9/mobile1.1 TABLE runtime at its existing loopback address. This supersedes the unchanged-runtime statements in the historical acceptance entries below. Read-only inspection froze its actual old classpath; old-runtime and old-after-new HTTP/login checks passed on historical and fresh closed backups before startup. Fresh copied invariants preserved every original column, row count, password/device-credential hash, barcode and UTC timestamp. Both original accounts passed live login, authenticated metadata and logout; ordinary semantic queries confirmed two devices and three scans, including the leading-zero barcode. The normal Android installation and peer services were preserved. Private backup/runtime evidence is retained in the task cache; old PID-specific maintenance helpers must never target the replacement JVM.
-
-Optional consent-based whole-device viewing is under implementation as an additive extension1.2 contract; it is not part of that running, qualified1.1 runtime. Android diagnostic checkpoint `6f25562` is published to its existing PR after instrumentation compilation; fresh hosted results remain pending. The actual trusted-scanner trigger attempt is unverified. Production signing/distribution remains the final owner decision.
-
-The initial1.2 reactor now passes39 server and six real-HTTP demo tests with normal Checkstyle, no failures/errors/skips, unchanged qualified-core hashes and unchanged1.0/1.1 baselines. Independent changed-file source review found no concrete introduced security finding; Android consent and projection acceptance remain open. The diagnostic Android checkpoint subsequently passed CircleCI37 native tests and unit tests; its earlier intermittent focus-owner cause remains unproven.
-
-Exact-source core `ecf0f550a0357cec6387c2b54efca128a405a629` with server `b14d925b741e815d1cfa4f62301f19207f25b03f` now passes fresh37 server/five demo tests, strict runtime provenance and all15 browser cases (zero skips/flaky/failures). The runtime has195 hashed JARs,2,440 unique QQQ classes, zero duplicate QQQ classes, patched Guava33.7.2-jre and H2 2.2.224. Core's full selected closure separately passes4,507 discovered/16 existing skips/zero failures/errors. See [qualification scope](API19-CONSUMER-ACCEPTANCE.md). No operator runtime was upgraded by this acceptance.
-
-The demo now imports the QQQ BOM using its own `qqq.version`, so an explicit version selection governs its complete transitive QQQ runtime. Private source qualification caught the prior mismatch: the scanner's installed POM retained its default RC.20 property, while the demo override selected a newer direct RDBMS dependency. The strict runtime verifier rejected the mixed core/Javalin/OpenAPI versions and older Guava despite passing tests. The first BOM-aligned run then exposed the demo's explicit JUnit 5.11.4 aggregate mixing an older API with the BOM's JUnit 6 engine; the demo now uses the BOM-managed test engine and its matching API/platform. The coherent candidate's fresh acceptance is recorded above; passing tests from the earlier mixed runtime did not establish that result. No operator runtime or shared Maven repository was changed.
-
-The normal operator demo was upgraded in place to mobile extension1.1 with a closed owner-only backup: two accounts, two devices (one approved), three scans, credential hashes and timestamp instants were preserved. Both original passwords authenticated after startup. Its JVM currently uses UTC because the copied upgrade exposed H2 converting legacy zoned timestamps using the workstation zone. The canonical H2 schema now begins by setting its migration connection to UTC, protecting both direct schema consumers and the demo initializer. A no-install reactor verifies the freshly packaged base resource: 37 base tests and five demo tests pass, with zero Checkstyle violations, including a file-backed America/Chicago child-JVM regression over all eleven converted timestamp columns, multiple source offsets, preserved passwords/approval/barcodes and an idempotent second startup. The isolated old-schema resource without the UTC statement fails with the expected six-hour winter timestamp shift; the tested jar resource hash matches the canonical source. This source change does not restart the operator runtime; it remains safely mitigated with UTC.
-
-The optional Record Files consumer now explicitly defaults to frozen0515 and its separate isolated-m2-0515 cache. Fresh normalized-heartbeat base37 and optional18 pass, with214 runtime jars/3180 classes/zero duplicates. Immutable evidence is retained under integrations/record-files/evidence/20261031-124632Z. Earlier0352 native acceptance remains historical;0515 is a new server consumer qualification, not an operator upgrade. Published dependency coordinates and hosted optional CI remain blocked on the upstream handoff recorded in HOSTED-CI-DEPENDENCIES.md. New API1.9 native Authentik metadata is being developed in an isolated core worktree and is not part of this server's adopted dependencies.
-
-Hosted Android acceptance exposed a heartbeat revocation defect after the published checkpoint: pending/revoked devices could keep receiving successful heartbeats and remain signed in. The fix checks approval under the existing activity lock before observing activity, and the route filter avoids pre-observation for canonical and accepted trailing-slash heartbeat paths. Both defects were independently reproduced before correction. Final root verification/install passes 37 tests and demo verification passes four tests, including the real HTTP no-side-effects regression and standalone presence case. Native hosted confirmation on the new server revision is still required; earlier static zero-findings results do not prove absence of this defect.
-
-Server checkpoint `0926550` includes 37 passing root tests, two HTTP acceptance cases, a passing standalone file-backed presence regression and 15 passing browser cases. The optional Record Files module adopts frozen bundle `retained-contract-20261031-0352`; 18 guarded integration/contract tests pass. TC22 navigation (12 cases), orientation, offline licenses, synthetic photos and the complete screen-viewing/session-end scenario pass on Android checkpoint `d5b5580`. These do not imply an operator-runtime upgrade or actual camera-lens acceptance.
-
-The full server deep static security scan of `0926550` completed and its canonical report was sealed on October 31 with no reportable findings. Coverage excludes external dependency implementations and production configuration; no new runtime tests were executed by the scan. The known external core DEBUG session logging issue, immutable Record Files publication/CI and production provider qualification remain open. Android's final full scan is still pending. A user-requested single-hamburger navigation correction is now being implemented after the published Android checkpoint; its new tests are not yet run.
-
-The normal operator demo and normal TC22 package remain unchanged. A separate temporary visual demo showed the new menu on the TC22; the user stopped computer control and retains the device. Do not restart, uninstall or drive that demo until coordinated. Signing/distribution remains deferred to the final step.
-
-The local emulator is closed after the user confirmed it caused workstation-wide stutters. TC22 is connected; do not restart the emulator automatically. Builds are serialized with bounded workers. Existing operator demo and handheld state remain preserved. Android85 JVM tests and zero-error/zero-warning lint pass at the last compiled checkpoint; newer changes must be verified again.
-
-The active goal authorizes completing and publishing the project, superseding historical artifact-publication deferrals below. However, on October31 the owner explicitly deferred signing and distribution until the final step because the channel is undecided. Complete implementation, final audits, tests, documentation and ordinary hosted CI first. No signing key, production release, merge or deployment is claimed.
-
-## Active: device sessions, live screen viewing and 1.0 audit
-
-Additional user scope: unique short device names assigned at setup/approval, editable names/descriptions, independent approval/presence, online fleet view and foreground GPS with age/accuracy. Camera/gallery photos use the separately developed Record Files qbit. The Build QQQ Documentation agent owns it and `qbit-record-files/docs/INGESTION-CONTRACT.md` documents the implemented record-files1.0 semantic capabilities/create/status/chunk/finalize/cancel operations and durable receipts. The October31 checkpoint above supersedes earlier proposed-only contract status. Native photo acceptance and the final authorization guard remain pending; unavailable capabilities stay hidden.
-
-The user requires all device/session history, live activity and actual application-screen viewing in QQQ administration, plus session termination. Implementation follows [DEVICE-SESSIONS.md](DEVICE-SESSIONS.md): ordinary QQQ tables/widgets/processes, server-owned authenticated bindings, an additive 1.1 semantic extension and demand-based bounded screen frames. Native and browser actions require full E2E coverage, including record and bulk entry points.
-
-The user also requires independent in-depth security, architecture, coding-standards and coupling/cohesion reviews of both complete repositories before a production-ready 1.0. [PRODUCTION-READINESS.md](PRODUCTION-READINESS.md) tracks the gates and exact baseline evidence. Plan: complete the session feature and tests; freeze final revisions for independent audits; remediate and verify findings; complete physical and release/operations acceptance. Deployment/distribution details have been requested. No 1.0 readiness or release is claimed.
-
-## Current: semantic API migration
-
-The qbit registers mobile-scanners 1.0.0 through QQQ's extension registry. Device enrollment/current status, branding and connectivity use `/qqq/v1/qbit/mobile-scanners`; discovery advertises the relative prefix `/qbit/mobile-scanners`. The generated OpenAPI includes typed device and scanner event/acknowledgment schemas, stable operation IDs and standard errors. Legacy standalone mobile routes are removed. [UI-API.md](UI-API.md) describes the contract and versioning policy.
-
-Root `verify install` passed 23 tests, including the extension contract baseline checks; demo `verify` passed one real HTTP discovery/schema/error/lifecycle scenario. All six migrated browser E2E scenarios passed in 2.9 minutes. Native integration exposed an unregistered Android client channel returning HTTP400; the qbit now registers `android` without replacing existing channel policies. The real HTTP regression sends `X-QQQ-Client: android/qqq-mobile` on all requests and passes. Android requires `android` in discovery's `clientChannels`; its combined JVM suites passed 53 tests (core 21/mobileapp 23/scanner 9), with six shared native UI tests also passing. Final lint passed with zero errors and six warnings; debug and E2E APK builds passed. Five native scanner scenarios passed with the OpenAPI request audit: incompatible core version, missing extension, missing Android channel, baseline scan flow and additive future metadata. The final native administration form scenario passed in 255.917 seconds after correcting completion handling for a COMPLETE response without `nextStep`: approval, revocation and cancellation completed, with all 31 requests matched to 13 published operations. All six native scenarios passed across the original and focused reruns; this is not a claim of one uninterrupted six-case run. All hosted checks passed for published server commit `7dd02b8874882ca2edcdcd89109b3dee6b4b0c88`: CircleCI setup/verify, CodeQL, Windows helpers and the demo HTTP/browser E2E job.
-
-Active plan: publish the companion Android checkpoint pinned to verified server code `7dd02b8`, then add the requested device/session activity, session termination and on-demand app-screen viewing. Physical connection-loss/retry and revoke-denial checks are deferred to acceptance with those session controls; the persistent server and USB forwarding are restored. The local server and emulator restarted after the workstation crash with data preserved; the backend administration UI was visibly signed in. The physical TC22 is identified through authorized USB debugging, running Android 14 and DataWedge 13.0.325. The debug app is installed and signed in. Approval from the browser record's Actions menu visibly reported one device approved; the handheld then opened the native app catalog and Scan Capture process. Updating the APK preserved its login. DataWedge is configured for package `io.qrun.mobile.scanner`, activity `*`, barcode input enabled, keystroke output disabled and Intent Output enabled. Intent delivery uses Broadcast, action `io.qrun.mobile.scanner.SCAN`, category `android.intent.category.DEFAULT`, and an explicit target package with signature checking enabled. Two deliberate physical trigger presses were confirmed by the user and produced two persisted records visible in Barcode Scans. A stored row matched the TC22 receipt for `QQQ-TEST-123456`, CODE128, source `scanner`, user `scanner`, TC22/Android 14/app 0.1.0, app `mobileScanApp`, process `mobileScanCapture`, and capture/receipt timestamps. Basic physical Code128 delivery and persistence passed. A subsequent physical QR scan was acknowledged on the handheld and independently visible in the backend as `001234567890`, `LABEL-TYPE-QRCODE`, source `scanner`, with matching TC22/user/app/process and capture/receipt metadata. Three physical records are verified: two deliberate Code128 captures and one QR capture. Physical QR delivery and leading-zero preservation passed; physical connection-loss/retry and revoke-denial checks remain pending. The old semantic-gap note below is superseded by this implementation status and the current TODO.
-
-## Verified: record and bulk device administration
-
- User reported Approve Device did not work from a device record and required proper E2E coverage for every process, including single-record and bulk entry points.
- Root and real HTTP regressions reproduced the missing selected device ID. Approval/revocation now prepare a stable selection, show confirmation, apply only after confirmation, and display a result/count. Explicit selected IDs and native select-all/first-N filters are supported up to 100 devices; oversized selections fail explicitly.
- The process stores selected IDs in native process records, ignores replacement IDs submitted at confirmation, rechecks administrator permission, and validates all targets before changing any. Standalone manual ID entry remains supported.
- Root verification/install passed 21 tests and Checkstyle. Demo verification passed the real HTTP scenario covering single-record approval, both bulk selection modes for approve/revoke, unselected-device isolation, visible results, scanner permission denial, scan persistence/retry, and revoked-device denial.
- Restarted the persistent local demo on port 57832; public status returned `ok`. Accounts, database and emulator forwarding were preserved. Dedicated scanner-host native E2E passed (one complete real-server scenario, 50.932 seconds); Android verification also passed 28 JVM tests, lint/build and workflow syntax. Test APKs were removed and the normal scanner restored.
- Browser E2E passed all six scenarios in 2.7 minutes: record approve/revoke with results and return navigation, checked-row bulk with untouched-device assertions, standalone manual entry, cancellation, full-query selection, and first-N selection with independent persisted-state checks. Tests use the packaged frontend and a temporary real backend. The fixture authenticates through the real API and supplies the nonsecret `qqq.sessionHint` marker so the UI resumes and validates its HttpOnly cookie. Browser checks now run inside the existing required demo CI job; native E2E runs in the Android push/PR emulator lane. New-head hosted results remain separate from these local passes.
- UI/UX API clarification: the Android app uses `/qqq/v1` metadata/process operations, but full semantic-client conformance is unfinished. Version/feature negotiation, broader native component handling and migration of separate `/mobile/v1` routes into a registered UI API extension are tracked in TODO; do not describe the current client as fully conformant.
-
-2026-10-30 correction: native authentication metadata is served at `/qqq/v1/metaData/authentication`. The device-header guard now exempts that exact public path; the previous legacy-only exemption caused HTTP403 on app restart after enrollment when device headers were present before a user session was restored. A real HTTP regression failed before the fix and passed afterward with stale, pending, invalid-token and revoked device headers. Protected metadata/process/scan authorization still fails appropriately. Root13 tests, Checkstyle and demo HTTP acceptance passed; the local demo was restarted on57832 with its persistent database and accounts preserved.
-
-## Current repository and demo state
-
- GitHub repository created at https://github.com/QRun-IO/qbit-mobile-scanners with `develop` as default. Initial signed commit `abbcc39` is published. Companion Android implementation is in https://github.com/QRun-IO/qqq-android/pull/8.
- Hosted initial-commit checks passed: CircleCI `setup`/`verify`, CodeQL `analyze / Analyze branch source`, demo HTTP acceptance and Windows helper analysis. CircleCI dynamic configuration is enabled. Maven artifact publication remains disabled.
- Runtime branding is configurable on the server before login; the shared Android APK uses the customer name, primary color and optional HTTPS logo. Public branding/status endpoints carry no credentials. Root tests now pass 13 cases; demo HTTP acceptance also passes.
- Windows demo helpers store generated demo passwords using per-user Windows DPAPI outside the repository. An Android 15/API35 emulator is running with WHPX; six native UI instrumentation tests passed. Physical TC22 acceptance is still pending.
- The current workstation demo uses loopback port 57832 because other services occupy the conventional ports. `adb reverse tcp:8080 tcp:57832` preserves the Android server URL `http://127.0.0.1:8080/`. Start it again with `pwsh -File scripts/Start-Demo.ps1 -SkipBuild -Port 57832` after stopping the existing instance. See `LOCAL-DEMO.md` for login helpers.
- The earlier verification/handoff notes below describe the initial implementation before repository publication and emulator setup.
-
-## Confirmed scope
-
- Native Android host for Zebra TC22 and other handheld scanners, extending `qqq-android`.
- Server-defined native screens and QQQ process actions, using existing QQQ metadata.
- Online only for version one; no offline scan queue.
- Local demo server with real QQQ login and required administrator device approval.
- First app: barcode capture into a QQQ table with scan, user, device and timestamp metadata.
- User authorized Codex agents for implementation and subsequently requested GitHub repositories and standard project files. Repository creation and pushes are authorized; artifact publication remains disabled.
-
-## Completed plan
-
-1. Established enrollment and scan contract using existing QQQ APIs.
-2. Implemented qbit tables, native metadata/processes, approval/revocation and guarded routes.
-3. Added Android scanner host, table-based login/enrollment gate and Zebra DataWedge input.
-4. Added a file-backed H2 demo and verified native login, approval, scan, retry and revocation over HTTP.
-5. Built the Android debug APK and documented TC22 hardware acceptance.
-6. Added standard repository/community files, current shared CircleCI QBit configuration, CodeQL, Dependabot, demo HTTP and Windows-script CI, and a documented publishing policy.
-
-## Baseline and ownership
-
- QQQ baseline: 4.1.0-RC.20. The local 4.0.0 middleware does not support Basic sign-in through `manageSession`; RC.20 does.
- Backend agent: qbit main source, unit/integration tests and root POM.
- Android agent: `qqq-android` source and scanner application module.
- Toolchain agent: Android SDK installed after explicit user approval of required Google terms.
- Parent: local demo, cross-component verification and documentation.
+The [local demo](LOCAL-DEMO.md) uses public QQQ `4.1.0-RC.21`, released Printing `1.0.0`, and qualified document/files/scripting owner inputs. Host port is `57832`; device port 8080 forwards to it, retaining the app URL `http://127.0.0.1:8080`. Contract versions remain UI API 1.10, mobile-scanners 1.5, printing 2.3 and mobile-record-files 1.0. This loopback demo is separate from HTTPS production deployment.

 ## Verification

- Qbit: `./mvnw.cmd -q verify install` passed 11 tests (7 H2 behavioral/security tests and 4 inherited guardrails), with Checkstyle passing.
- Demo: `../mvnw.cmd -B verify` passed Checkstyle and one real HTTP acceptance scenario. It verifies QQQ login, anonymous and pending-device denial, operator/admin separation, approval, async native process capture, same-event deduplication, SQL provenance, bad/missing device credentials, revocation while a process is open, logout and session replay rejection.
- HTTP fixtures verify the actual native `composite`/`SCANNER` widget payload. The Android tests deserialize these real metadata/process/init responses.
- Android: core/mobileapp/scanner JVM suites passed 19 tests, no failures or skips. `lintDebug` and `assembleDebug` passed. Lint has 0 errors and 5 warnings: 3 inherited Navigation custom checks skipped due to API incompatibility and 2 dependency/version notices.
- Debug APK signature verified. Path: `../../qqq-android/scanner-host/build/outputs/apk/debug/scanner-host-debug.apk`.
- APK SHA256: `B3E160CE3279C369CEDB425AC6E777A2729CE8A2E430E7D6F46D35C6376F8214`.
- Android SDK location: `C:/Users/james/AppData/Local/Android/Sdk`; SDK 35, build-tools 34/35, Gradle 8.7.
- `adb devices -l` returned no attached devices. No physical TC22, camera, or emulator acceptance performed.
- Repository bootstrap verification: CircleCI setup validated against the private QRun-IO orb with explicit organization scope; Actionlint passed for both workflows. Current shared generator accepted the manifest and selected verification only for seven branch/tag cases. All publication switches are false. Root 11 tests and demo one scenario were rerun successfully after repository metadata changes.
+- The combined five-module `verify` (2026-11-05, base `9e8685f` plus the storage fixes) passed **196 server tests** with zero failures, errors and skips and zero Checkstyle violations: scanner 53, base demo 8, mobile Record Files 22, Echo 74, Echo demo 39. It used qualified private owner dependencies; there is no public-dependency or physical-output qualification, and the gate must be repeated when the public cohort is adopted. The new build parent's report-only schema-location/contract-test findings remain visible.
+- Storage evidence: `PrivateObjectFilesTest.concurrentSameKeyWritersLeaveOneWinnersBytesAndMetadata` and `dotBucketsAreRefusedAndValidBucketsStillWork`; recovery acceptance `EchoDemoAcceptanceTest.restoredSnapshotKeepsScanAndRetainedFileAndRevertedApprovalStateIsReaudited` (details in [OPERATIONS](OPERATIONS.md#isolated-local-demo-recovery-acceptance-automated-passed)).
+- Android passed **232 unit tests**, lint with **0 errors/0 warnings**, and the debug APK build. E2E APK/instrumentation builds and eight runner guard tests also passed.
+- Isolated MC9400 native acceptance passed search/filter/paging/Back, grouped/related records, camera/gallery upload, parent-scoped saved-photo list, approved preview, rotation, pending-upload navigation protection and forced-logout cleanup. All requests matched the semantic API. Process-photo regression also passed.
+- The final date-only correction received unit/lint/build checks and actual TC22 verification. Actual-device screenshots confirm Actions → Add photo, dates/timezones, currency, related tabs, photo empty state and return to page two. Synthetic camera/gallery inputs in automated acceptance are not a new operator camera report.
+- Earlier 135/188/198/377-test cohorts and 15 browser E2E cases are historical evidence, not a fresh run against future public dependencies. The snapshot source comparison applies to its original revision only.
+- 2026-11-06, branch `fix/refresh-device-versions`: the MC9400 in-place 1.0.0 to 1.0.1 update left the device record and every later scan reporting `appVersion` 1.0.0, because only enrollment ever wrote `manufacturer`/`model`/`osVersion`/`appVersion` and no later client request carried them. Extension 1.6 adds the same optional fields to `MobileScannersHeartbeatRequestV1`; the heartbeat refreshes the device record when a value differs and scans copy the refreshed record (see [UI-API](UI-API.md)). The Android host change (send `osVersion`/`appVersion` on heartbeat) is on the same-named branch in the Android repository; devices need that client build before their versions refresh. Root module: 56 tests, zero Checkstyle violations, new baseline `mobile-scanners-1.6.0.yaml`.

-## Handoff and remaining scope
+## Handhelds and remaining limits

- Follow `TC22-ACCEPTANCE.md` for local credentials, loopback demo, USB forwarding, DataWedge profile and device tests.
- Runtime demo server is not left running. No user credentials were created outside temporary test databases.
- First host supports QQQ table-based authentication; other providers show an explicit unsupported message pending configuration.
- Server enforces approved device plus authenticated user, including async execution. Enable QQQ core permission enforcement when embedding the qbit.
- Only a current unacknowledged scan is retained in memory for explicit retry. Closing/resetting the app is not an offline queue.
- The H2 schema is supplied; migrations for other databases and deployment authentication remain host-owned.
- Pending physical acceptance is tracked in TODO. GitHub bootstrap and hosted checks are separate from artifact release or production deployment; use `CI-CD.md` for the repository settings and release enablement policy.

-## Native authentication review follow-up
-The first optional provider-logout compile failure and alternate authentication-source hint gate are corrected in a new frozen source candidate; its isolated focused build is running. Independently, native login does not currently carry/validate the original request nonce against the provider ID token. PKCE code binding is present; no account-takeover exploit is claimed. Explicit provider-bound claim/nonce validation and real-provider acceptance remain required before production authentication closure.
+Signed Android `1.0.1` (code 3) was built from the identical merged source tree (PR 15) and installed in place on the MC9400. The installed bytes match the built APK, login and enrollment were preserved, the authorized Scan Capture screen reopened, and the HTTPS connection was established. Pending: the MC9400 physical trigger scan, native Authentik login/logout/account switching, the public dependency cohort and final distribution.

Core combined nonce/test corrections remain in progress; initial diagnostic failures stay failed.
+The November 4 TC22 operator group pass remains accepted and is not requested again. Physical GS1 print/rescan, provider callback acceptance and fleet rollout remain open. Echo supports only its documented [barcode profiles](../examples/echo/README.md#fidelity-and-limits). Company profile/wallpaper is separate tracked scope, not a blocker for this release goal.
+
+Operations and recovery guidance is in [OPERATIONS](OPERATIONS.md). The automated stopped-H2 plus object snapshot/restore case passed as isolated local-demo recovery acceptance (no physical printing, no normal demo data changed). Enterprise object-store/HA and non-H2 databases are unsupported and unqualified, not release tasks. The [dated review](REVIEW-RECONCILIATION-2026-11-05.md) records its scope and supplement. Public owner dependencies require a separate reviewed adoption and a new gate.

+# TC22 visual and interaction review
+
+Follow-up: all eight findings were addressed in the existing app and maintained demo. See [implementation and verification](history/MOBILE-UX-2026-11-05.md). The review below preserves the original observations.
+
+Reviewed November 5 on the actual TC22 running the existing app and maintained demo, using synthetic Test Orders. Directly inspected the first and second table pages, all six order groups, photo controls, related items, an item detail, history links and Back navigation. This is a visual/interaction review, not a new camera, printer or hardware acceptance claim. No records or photos were changed.
+
+## Assessment
+
+Readable and functional, but the current presentation is inefficient for repeated handheld work. Large text and buttons help readability; hierarchy, navigation and access to frequent actions need improvement. The data volume exposes limitations that smaller records concealed.
+
+## Prioritized changes
+
+| Priority | Observed issue | Recommendation |
+| --- | --- | --- |
+| P1 | Page two → order 26 → Android Back returns to page one. | Preserve table page, scroll position and filters per navigation entry. Verify Back after multiple record visits. |
+| P1 | Reaching photo buttons required five long swipes from the top of order 1. Items/history follow all 39 fields. | Add direct Details, Items, Photos and History navigation, with a prominent Add photo action. Make detail groups collapsible and provide a section selector. |
+| P1 | Toolbar says only “Record”; order identity disappears while scrolling. Child records use the same title. | Keep a compact record reference and record type visible. Show a parent-order link on item details; keep record labels out of telemetry. |
+| P1 | A 1,000-row list has Previous/Next/Refresh but no visible search, filters, count or page indication. | Add server-backed search, relevant filters and “26–50 of 1,000.” Consider scan-to-find where declared metadata supports it. |
+| P2 | Table entries are centered blue links with uneven wrapping; child descriptions occupy three lines. History shows only event identifiers. | Use left-aligned rows with a strong reference, concise secondary text, status and a clear navigation affordance. Show item quantity/SKU and history timestamp/status through metadata-defined summaries. |
+| P2 | Item heading repeats the full description in very large type, then repeats it as a field. Persistent branding/header and diagnostic footer consume substantial space. | Use a short reference heading and secondary description. Consolidate the header and reduce connected status to a compact indicator; retain accessible text and touch targets. |
+| P2 | Dates/timestamps and money read like raw values; timestamp example includes `T` and `Z`. | Apply metadata-aware currency, units and localized date/time formatting with timezone context. Preserve leading zeros. Show an explicit empty-value indicator. |
+| P2 | Photo controls offer capture/select but this screen provides no visible saved-photo gallery or attachment count. | Add thumbnails/count, preview, upload progress and clear pending-review/retry states. Keep the destination record visible near photo actions. |
+
+## What works
+
+Text is legible, field labels are distinguishable, sections have clear headings, and the blue photo buttons are easy to identify. Leading zeros, Unicode and multiline values displayed correctly. Parent-to-item navigation worked. Table pagination is available without scrolling the whole page.
+
+## Suggested order
+
+Fix navigation state first. Then add persistent record identity and direct photo/related-record access. Next improve list summaries/search and reduce repeated content. Finish with formatting and attachment presentation. Implement generic metadata-driven controls rather than order-specific layouts. No UI fixes were made during this review.

- [ ] Finish final hosted checks and remaining physical/provider acceptance; source compliance is not production release approval.
+## Needs an owner outside this repository

- [x] Upgrade the normal local demo to qualified API1.9/mobile1.1 with fresh closed backup, original-data invariants, recovery qualification and live verification of both existing accounts and preserved devices/scans.
- [x] Implement/review additive extension1.2 whole-device source with explicit Android consent, mode-bound leases and automated controls, preserving1.1 app-content compatibility.
- [ ] Complete actual Android projection/notification/Home/Stop/lock/rotation/expiry/remote-logout acceptance; normal server remains mobile1.1.
+- [ ] **Public document/files/scripting artifacts.** The document owner publishes a coherent set (Generation, its Printing and Record Files bridges including copies support, Record Files, Scripting) as public Maven artifacts. Until then the Echo modules and the optional Record Files integration build against qualified owner inputs and only `qqq.version` and `printing.version` resolve publicly. The owner's packaging is in progress; no completed version is known, so do not invent coordinates or change POMs ahead of it.
+- [ ] **Core, Collaboration and Next UI foundations.** Adopt the public versions when the owner releases them, as a normal reviewed dependency change with a fresh full gate.

- [x] Qualify the demo BOM import and managed JUnit engine with fresh37 server/five demo tests, exact runtime module/Guava/H2 provenance and all15 single-record/bulk browser cases; see [acceptance evidence](API19-CONSUMER-ACCEPTANCE.md). The operator runtime remains separate.
- [x] Preserve legacy timestamp instants in the canonical supplied H2 schema with an explicit UTC migration connection; verify non-UTC file-backed upgrade, unchanged passwords/approval/scans and repeated initialization. The operator upgrade is preserved with UTC; a no-install reactor passes 37 base tests and five demo tests using the freshly built schema.
- [x] Implement unique short names, editable names/descriptions, additive H2 migration and protected profile editing; qualify the preserving upgrade of the operator database before deployment.
- [x] Implement separate approval/presence states, online-only fleet query and foreground location with accuracy/age and permission-denied behavior; actual GPS-fix acceptance remains in the release gates.
- [x] Implement the optional Record Files contract/native capture/association path and qualify the final coherent core32/scanner1a3 consumer cohort: 39 scanner, six demo HTTP, 18 Record Files and 15 browser cases. See [qualification scope](../integrations/record-files/docs/CORE-32DF-CONSUMER-QUALIFICATION.md); this is not a files-owner full-suite or default-adoption claim.
- [ ] Qualify coherent immutable/default RF dependencies and actual TC22 camera/gallery permissions and durable authorized association; no normal-runtime adoption is implied.
+Note: redesign of the shared CI pipeline is outside this scanner/local Echo scope and is not tracked here; the local demo does not depend on it.

- [x] Device/session history, live activity and demand-based actual app-screen viewing through native QQQ administration and semantic extension 1.1.
- [x] Single-record and bulk End Session process with server-enforced invalidation, audit and browser/native E2E coverage.
- [x] Complete and seal the full server deep static security review of `0926550`; no reportable findings, with external implementation/deployment limitations retained.
- [ ] Complete final revision/scope reconciliation of historical security reports and remaining external deployment/provider gates. Independent architecture A1–A11 source closure and the filesystem regression correction are recorded; do not relabel partial/historical reports as a new exhaustive scan.
- [ ] Complete production 1.0 gates in [PRODUCTION-READINESS.md](PRODUCTION-READINESS.md), including physical acceptance and deployment/release requirements.

+Retention stays indefinite by default and any change is a host-owned policy ([operations](OPERATIONS.md#retention)). Enterprise object-store and high-availability recovery, and database backends other than H2, are unsupported/unqualified deployment options, not tasks of this release. The 2026-11-05 gate (196 tests, zero failures/errors/skips, zero Checkstyle violations) used qualified private owner dependencies; the required public-cohort rerun remains listed below.
+- [ ] Optionally correct the generic 409 text in `MobileJsonSpec` (screen upload is a stale-frame conflict) with a patch version bump and regenerated contract; deferred.
+- [ ] Complete the authorized readiness work in [the active plan](GS1-RECORD-PHOTOS-PLAN.md), retaining explicit external/hardware gates.

-Future scope (not version one): offline queue, camera-based barcode decoding, kiosk/MDM provisioning, broader native screen coverage, fleet rollout. Optional record-photo capture is implemented; its remaining qualification is tracked above.
+- [ ] Re-run the full gate (root, demo, Echo, Echo demo, Record Files, browser E2E) on whatever dependency set is adopted next, and record the actual counts.
+- [ ] Qualify the bounded GS1-128 profile and keep explicit refusals for other GS1, ECI, structured and binary scanner profiles in Echo ([limits](../examples/echo/README.md#fidelity-and-limits)).

- [ ] Complete the optional semantic API1.10 provider-logout capability and client AppAuth end-session handling; keep local cleanup reliable on provider failure, qualify real A-to-B handoff, and apply the user's pending sign-out policy. Existing prompt-only retained-SSO handoff is not accepted.
+## Hardware and device follow-up

- [ ] Validate native OIDC ID-token claims and original request nonce before creating the QQQ session. Review confirmed request continuity and S256 PKCE exist, but expected nonce is not currently carried to the server exchange. Add explicit semantic capability/wire compatibility and rejection tests; retain real-provider nonce acceptance as pending.
+- [ ] **MC9400:** one physical trigger scan, then confirm the backend record. The signed 1.0.1 (code 3) build is installed in place and approved ([session state](SESSION-STATE.md#handhelds)).
+- [ ] Native Authentik login, logout and account switching on a handheld (not yet tested).
+- [ ] Optional: capture per-case evidence (photos, logs, a scanned-back label) on a future run. The November 4 operator pass is accepted as is and is not to be requested again.
+
+## Release (deliberately last)
+
+- [ ] Final distribution of the signed 1.0.1 build and the public dependencies it waits on. Signing is done: the build was installed in place on an MC9400 through ADB, preserved enrollment, and reopened Scan Capture against the HTTPS server. Remaining device checks are listed above; no automatic APK-signing CI is qualified.

 # Mobile Scanners semantic UI API

-Mobile Scanners is an independently versioned QQQ UI API extension. `MobileScannersQBitProducer` registers the `mobile-scanners` contract, currently **1.3.0**, through `MiddlewareSpecExtensionsMetaData`. The framework generates its routes, discovery advertisement and merged OpenAPI from the same endpoint specs. Optional operator-consented device-screen viewing is described in [DEVICE-SCREEN-VIEWING.md](DEVICE-SCREEN-VIEWING.md); app-content remains the default. There is no separate `/mobile/v1` API or legacy alias.
+Mobile Scanners is an independently versioned QQQ UI API extension. `MobileScannersQBitProducer` registers the `mobile-scanners` contract, currently **1.6.0** (core UI API 1.10 on the maintained local server), through `MiddlewareSpecExtensionsMetaData`. The framework generates its routes, discovery advertisement and merged OpenAPI from the same endpoint specs. Optional operator-consented device-screen viewing is described in [DEVICE-SCREEN-VIEWING.md](DEVICE-SCREEN-VIEWING.md); app-content remains the default. There is no separate `/mobile/v1` API or legacy alias.

 The host must also install `MobileScannersRouteProvider` on the same server. This provider binds verified device headers to the current request; it does not register additional business routes. Keep the versioned QQQ routes enabled. The qbit registers the `android` client channel while preserving the host's existing channel policies. The demo disables legacy unversioned middleware routes.

+All seven operations also declare 400, 401, 403, 404, 429 and 500 error responses (`BasicErrorResponseV1`). The published YAML labels every operation's 409 "Installation already enrolled"; that text is accurate only for enrollment. Session behavior is in [device sessions](DEVICE-SESSIONS.md) and [screen viewing](DEVICE-SCREEN-VIEWING.md).

 Public discovery, OpenAPI, branding and connectivity ignore stale device headers. Authentication discovery/session/logout also remain available when a previously enrolled credential is no longer valid. Responses from extension handlers use `Cache-Control: no-store`.

 Enrollment takes `MobileScannersEnrollRequestV1`: required canonical UUID `installationId`, optional `displayName`, `manufacturer`, `model`, `osVersion` and `appVersion` strings, each at most 200 characters. The JSON request body is limited to 4096 characters. A duplicate installation returns HTTP 409 and never rotates or discloses its existing credential. A new installation starts `PENDING` and receives its private `deviceToken` once.

+Since extension 1.6, `MobileScannersHeartbeatRequestV1` also accepts the same optional `manufacturer`, `model`, `osVersion` and `appVersion` strings (at most 200 characters, 400 otherwise). An approved device's record is updated only when a sent value differs; omitted, null or blank values leave the enrolled values unchanged. Scan events copy the device record at save time, so an in-place app or OS update is reflected on the next heartbeat and every later scan, while earlier scans keep the versions that produced them. The Android host sends `osVersion` and `appVersion` on every heartbeat.
+
 Send `X-QQQ-Device-Id` and `X-QQQ-Device-Token` on authenticated device/core metadata, widget and process requests to this same origin. The device ID is a UUID; the token is private and at most 128 characters. These headers supplement the authenticated user session. They never replace user permission checks. Never put a token in metadata, URLs, process values, screenshots, logs or fixtures; never forward credentials to a branding asset origin. Store the issued credential privately. Only its digest is stored server-side.

 `devices/current` returns `deviceId`, `displayName` and `status`, never a token. `PENDING` and `REVOKED` devices may read their status. Scanner access still requires `APPROVED`, checked when launching and saving, including asynchronous/resumed execution. Device approval/revocation uses the ordinary QQQ processes, including single-record and bulk selections.

 Raw event fields and old receipts are consumed before capture, including rejected attempts, so the next submission cannot inherit a preceding type. Following steps use the nested accepted context. Historical NULL type/source values normalize for comparison and returned context without rewriting those rows or accepting a newly claimed known type on retry. Pre-1.3 process state containing a receipt without context fails closed: leave/cancel and reopen the scanner process. Logout and device re-enrollment are unnecessary.

+### Exact capture metadata in 1.5
+
+Extension 1.5.0 adds two optional flat string values to `MobileScannersScanEventV1` and, when present, to `MobileScannersScanContextV1`. Neither is a required key and old required fields are unchanged. Missing values are valid for older clients and manual capture.
+
+| Value | Rule |
+| --- | --- |
+| `aimIdentifier` | Exactly 3 characters matching `^\][A-Za-z][0-9A-Za-z]$`: the original AIM identifier from the scanner SDK, never guessed from `symbology`. |
+| `rawDataBase64` | Canonical standard padded Base64 of 1 to 8192 decoded bytes (at most 10924 characters): the byte-for-byte SDK `getRawData` result. The server does not decode it, strip prefixes or assume it equals the UTF-8 of `barcode`. It may include SDK code-ID framing, so it is exact SDK output, not symbol codewords and not evidence of attested scanner configuration. |
+
+A present value that is blank, not a string, malformed, non-canonical (missing or extra padding, whitespace, URL alphabet, non-zero trailing bits) or oversize is rejected by the server with no scan saved. A JSON `null` is treated as absent. Stored values are nullable columns on `mobileScan`; historical rows keep `NULL`, which means absent.
+
+Exact equality of both values, including absent versus present, participates in event retry binding: an identical retry returns the original row and scan ID, while changed bytes, a changed AIM identifier, or adding or dropping either value for an existing `eventId` is rejected like any other changed scan. The context contains these keys only when the accepted scan has them. Both input keys are consumed before capture (including rejected attempts) and any submitted `scanContext` is replaced, so the next event cannot inherit them and a client cannot forge them. They carry no identity and no trust elevation, and there is no decoder profile or trust field in this version.
+
+A client sends these fields only when the current server's `mobile-scanners` version is `>=1.5.0 <2.0.0`, the registered path is advertised and the server's process metadata permits them. Older servers receive exactly the legacy five keys (`barcode`, `symbology`, `scanSource`, `eventId`, `capturedAt`). Hardware qualification of AIM and raw-byte fidelity is separate follow-up work; this transport does not by itself establish exact barcode reproduction.
+
+Schema migration (H2, idempotent, nullable): `ALTER TABLE mobileScan ADD COLUMN IF NOT EXISTS aimIdentifier VARCHAR(3)` and `... rawDataBase64 VARCHAR(10924)` in `mobile-scanners-h2.sql`. Other backends must add equivalent nullable columns before deploying 1.5.0 servers; do not assume `ADD COLUMN IF NOT EXISTS` or the type sizes exist elsewhere.

 Do not refresh the release baseline to hide a compatibility failure. Additive compatible changes require a minor version increment; fixes require a patch increment. Breaking contracts require the corresponding new major contract and an explicit client migration. A server can change supported metadata/screens without rebuilding customer APKs; introducing a new required native component needs a shared client update and compatible contract negotiation.

 Root `verify` checks the committed fragment/baseline and public stale-credential behavior. Demo `verify` runs the real HTTP/authentication/process/H2 lifecycle, checks discovery and merged operation IDs/security/schema references, validates actual enrollment/device/SCANNER/event/ack payloads against served schemas, and checks structured errors and rejection of legacy routes.

+# Mobile record UX completion — November 5
+
+The [TC22 review](../TC22-UIUX-REVIEW-2026-11-05.md) identified eight usability issues. All are addressed in the companion Android application and this demo's ordinary metadata:
+
+- Table page/scroll/search/filter state survives record navigation and recreation; search, exact text filters and counts use the semantic query/count APIs.
+- Record identity stays visible above Details, related-record and Photos tabs. Groups collapse; a section selector and child-to-parent navigation shorten large records.
+- Left-aligned summaries, short item labels, localized dates/timezones, currency/units and explicit empty values improve readability. Diagnostic detail is behind Connected.
+- **Actions → Add photo** opens the existing camera/gallery upload flow. Saved photos are scoped to the parent, show lifecycle status and use the owner's authorized tracked download for available-image previews. Quarantined originals remain unavailable.
+
+Record Files deliberately refuses aggregate counts: the gallery uses bounded pages with one lookahead row, without weakening permissions. Images have bounded byte/bitmap memory, exact length/hash checks, same-origin authenticated delivery and no image disk cache. Navigation guards remain active during pending uploads, including rotation; logout removes owned temporary staging.
+
+## Verification and adoption
+
+The composed feature cohort passed 189 tests (scanner 53, base demo 8, mobile Record Files 18, Echo 74, Echo demo 36) with Checkstyle. Android passed 232 unit tests and lint (0 errors/0 warnings), plus debug/E2E/instrumentation builds and eight native runner guard tests. Isolated MC9400 rich-record acceptance passed grouping, related paging, search/filter/Back preservation, camera/gallery persistence, parent-scoped gallery, approved preview, rotation, blocked navigation and forced-logout cleanup. Process-photo regression passed separately. All native requests matched the published semantic API.
+
+The date fallback needed to recognize the server's default `%s` metadata and differing raw/display JSON representations. Regression tests and a final unit/lint/APK gate cover that correction; actual TC22 screenshots show formatted dates and timezone context. The final date-only change did not repeat the full native suite.
+
+The maintained server was updated with a database/object backup and no reset. The ordinary TC22 application was replaced in place after matching its signer; the installed bytes match SHA-256 `F71033C835AC3EB361A04D78C842947C5A04C85CE1AB1B999AA8CEFBFC9D7A95`. Login, enrollment, server address and existing data survived. Actual TC22 inspection confirmed Actions, Take photo/Choose photo, Details/Items/History/Photos, formatted values and order 26 → Android Back → 26–50 of 1,000. No real camera capture or print was submitted during this visual check.
+
+Earlier UX-build hashes `23BA59F0EEE34D5B9ABBE5D45158A57C98416A5D7D69337090129AB6C853EABC` and `25DAB25D92FF709E4DA5DAA9949A501113E71DC050FF12E07C17C06EE06514E5` were superseded by the date correction. The preceding rich-record preview is preserved [separately](RICH-RECORDS-2026-11-05.md).
+
+## Source and remaining limits
+
+The user authorized commit, push and merge after the local update. Latest upstream scanner PRs 17/18 are retained. Reviews: [scanner/server PR 19](https://git.kof22.com/QRun-IO/qbit-mobile-scanners/pulls/19) and [Android PR 15](https://git.kof22.com/QRun-IO/qqq-android/pulls/15), which includes actual TC22 screenshots. Publication switches and repository dependency defaults are unchanged.
+
+The combined source passed a fresh **193-test** server gate: 53 scanner, 8 base demo, 22 mobile Record Files, 74 Echo and 36 Echo demo, zero failures/errors/skips and passing Checkstyle. The inherited build parent adds four guardrail cases; report-only extension schema-location/contract-test findings remain visible. Every source/resource file in the isolated build was matched to the merged working tree by count and SHA-256. Owner-coordinate and Checkstyle-path overrides existed only in that verification copy. A direct build against the old default Record Files snapshot failed because its authorization API is missing; the qualified running-demo cohort passes. Public owner-dependency adoption remains separate work.
+
+The November 4 TC22 operator pass remains accepted. Physical GS1 print/rescan, MC9400 trigger acceptance, HTTPS/signed-build qualification and public owner-dependency adoption remain distinct open gates. No production release or new Maven artifact publication is claimed.

+
+# Mobile scanners 1.0 release gates
+
+Status: not release-ready. The user requested a full client/server audit and production-ready 1.0. This is an evidence ledger; a numerical quality score does not replace the gates below.
+
+## Current checkpoint — November 2
+
+Server `e3b775e` (Gitea PR 7) fixes the Generation/renderer output-limit mismatch and passes 45 Echo library plus 29 composed demo tests with zero Checkstyle violations. Android implementation `fb3cc5d`, published with documentation at `ffc5b49` (Gitea PR 10), passes 174 JVM tests, lint with zero errors and warnings, and the debug APK build. One local server on host port 57832 runs Echo, Record Files, Document Generation and Printing together (API 1.10.0, mobile 1.4.0, printing 2.3.0). The normal TC22 and the installed print client work against it, and the real 4x1 stock, media revision and Echo document are published and selectable. The earlier native acceptance (7 stages, 112 requests) used simulated printing and inputs.
+
+The synthetic HTTP event `ECHO-HTTP-TEST-001` has one matching scan and one actual ZPL print job in `SPOOLED`, with a Windows spooler job assigned and its process closed. A read-only recheck at 16:31 UTC confirmed that receipt, server HTTP 200, the running print service, and the TC22 showing Echo / Scanner ready / Connected. No Windows administrator prompt or printer pairing is pending. Paper output and physical TC22 print/rescan remain unconfirmed; see the [delivery receipt](../../examples/echo/demo/docs/echo-delivery-acceptance.json).
+
+Still not release-ready. Open: physical Code128 and leading-zero QR scan, print and rescan; extended barcode fidelity beyond the currently admitted types; full provider, camera, GPS, projection and device qualification; public coherent artifacts; primary Gitea CI; and final signing and distribution, which is deliberately last. Core PR 1337 was reviewed with its 57 focused tests verified, but normal CI and publication are not established and default dependencies are not repinned. Where dated checkpoints below describe the same-origin fix, printer connection, media, document or server composition as pending, this section supersedes them.
+
+## Superseded checkpoint — November 1, 17:34 UTC
+
+Server standards checkpoint0b53f34 is signed/pushed and all eight hosted checks pass; a fresh private API1.10 cohort passes39 server, six demo HTTP and18 Record Files consumer cases with Checkstyle. Client strict compilation and163 JVM tests pass; final TC22 native acceptance is running and the Query artwork density warning is being corrected before installation. About includes bundled Query artwork and the exact public Dogfooding/Query links.
+
+Actual Authentik desktop acceptance now passes real negative nonce rejection, A login, explicit company logout, old-cookie rejection, fresh B credentials and B principal in the same retained browser context, followed by B local logout/rejection. HTTPS verification remained enabled with profile-only fixture trust. The owned provider required its documented company invalidation flow; no global flow or default client sign-out policy changed. This closes the earlier desktop A-to-B handoff failure for the qualified API1.10 fixture, not the actual Android external-browser callback gate. The normal server remains API1.9/mobile1.1 and operator data is preserved.
+
+CorePR1369's new hosted run exposed a missing explicit architecture allow-list entry for extracted private-session logout plumbing; a narrow policy-conforming correction is under verification. Do not call final core CI green. Remaining physical GPS/camera/projection/lifecycle/retry, immutable files-owner handoff, deployment and owner-deferred signing/distribution gates remain open. Dated matrix rows below retain their earlier source/runtime scope and are superseded by this checkpoint where stated.
+## Current release ledger — November 1
+
+This is the current acceptance matrix; dated checkpoints below remain historical evidence. Android portrait-default source `7de2b5088fa376cb161ed5ac7e5358d2a2145d92` passes all eleven hosted checks. Documentation/QR fixture checkpoint `2e0fd962a7ece0f81328e5f9f05e4c1e2d77a853` does not establish physical QR acceptance. Server implementation `10416938724c9663d66f7848ff2b1a63fe635794` has qualified API1.9/mobile1.2 source evidence. Source publication, private consumer qualification and the installed operator runtime are distinct; no production APK or immutable dependency release is claimed.
+
+| Requirement | Accepted evidence and scope | Remaining release gate |
+| --- | --- | --- |
+| Current Android and CI | All eleven hosted checks pass at published Android8d8 (portrait implementation7de), including native navigation/input, PixelCopy and semantic E2E. The subsequent optional provider-logout working patch passes148 JVM tests, lint and debug build; its native tests compile but have not run. The completed-logout/enabled-action guard retains fresh-login/new-session assertions. Portrait default preserves explicit saved choices. | Physical operator navigation, lifecycle, ownership, outage/retry and leave/cancel walkthrough. Any later executable source needs its own verification. |
+| Trusted scanner ingress and hardware | Ordinary-UID/distinct-signer rejection of eight forged scans plus manual positive control; actual EMDK Code128 source/model/event proof: eight deliberate events on prior F3AF APK and one on the installed portrait-default C891 APK. Historical DataWedge evidence is separately retained. | Current leading-zero QR, repeated-intent/lifecycle/ownership matrix, connection failure and uncertain receipt/retry/leave acceptance. Code128 success does not qualify QR or every lifecycle path. |
+| Running operator deployment | Preserving coreecf/serverb14 UI API1.9/mobile1.1 runtime on127.0.0.1:57832; normal TC22 uses development APK C89161C522AA7DFFE09C009ABDE769C1BADB7E6C64BFCE699857062A1CEC6340 with signer/data backup preserved and portrait requested. | Supported production deployment, HTTPS/authentication, migration/recovery and release upgrade acceptance. No normal1.2/RF installation is implied. |
+| Source-pinned server/admin APIs | Server104 source:39 server/six demo/all15 browser cases,195 hashed JARs/2,441 unique QQQ classes/zero duplicates; record/bulk administration, profiles, presence, sessions and screen controls covered. Coreecf selected closure:4,507 discovered/16 existing skips/zero failures/errors. | Coherent immutable dependency publication and final supported deployment configuration. Default Maven dependencies still select RC.20; passing source-pinned consumers do not change that default. |
+| Authentik | Real Authentik2026.8.5 browser PKCE login established operator A; QQQ local logout invalidated its old cookie. With retained browser SSO, the next prompt=login silently reused A, so operator handoff failed. Optional semantic API1.10 RP logout and Android AppAuth handling are implemented but unqualified; the first core build found an API mismatch and review found an alternate-authentication-source gap under correction. | Correct and qualify the optional logout implementation, then prove real A→provider logout→B identity isolation. Native browser callback/lifecycle and user-selected sign-out policy remain pending. Existing failed retained-SSO evidence must remain failed. |
+| Optional whole-device viewing | Additive mobile1.2 server and consent-based Android source built/reviewed; mode/session-bound leases and bounded image ownership verified automatically. Normal server remains mobile1.1 and does not expose device-screen mode. | Actual OS consent/notification, Home/other-app pixels, Stop/lock/rotation, lease expiry and remote logout on the refined candidate. Separately preserve normal data before any coordinated1.2 upgrade. |
+| Camera/gallery and Record Files | Filesystem portability142 discovered/138 passed/four existing skips; metadata symlink-parent regression fixed and independently closed. Final coherent core32/scanner1a3 qualification passes39 scanner, six demo,18 Record Files and15 browser cases (78 total), with214 JARs/3,163 unique QQQ classes/zero duplicates and no separate filesystem override. Synthetic native camera/gallery/receipt cases remain separate evidence. | Coherent immutable supported RF/attachment-owner/core/RDBMS/filesystem tuple and default adoption, then actual TC22 lens/gallery permissions and durable authorized record association. The isolated coherent qualification does not establish the files owner full-suite/default publication gate or change the normal runtime. |
+| GPS and customer appearance | Foreground-only location/state/age controls and automated permission-denial/schema coverage; current basic operator display/navigation observed. | Real GPS permission/fix/disabled-provider behavior and customer-specific logo/physical appearance. |
+| Security, architecture and standards | Historical scoped security reports/remediations retained; independent architecture closure maps A1–A11 controls/tests. Whole-device changed-file review and follow-up found no concrete introduced issue; filesystem finding closed against corrected source/test evidence. | Final revision/scope reconciliation and unresolved external-provider/deployment gates. These reports do not become a new exhaustive scan or blanket production clearance. |
+| Release and operations | Release automation/source packaging independently reviewed; normal preserving migration/login checks passed. | Reviewed GitHub environment/tag protections, organization signing identity/recovery, actual signed APK upgrade/physical qualification and distribution decision. Signing/distribution remains owner-deferred until the final step. |
+
+The local emulator remains off because of workstation stalls. Disposable QA and private fixtures must not replace the normal package/runtime or clear operator data. No numerical quality score replaces the remaining gates.
+
+Historical November1 display observation retained: the handheld's black desktop mirror was not proof of a crash. Direct inspection found the normal process alive/resumed, no crash-buffer entries and connected sign-in; login reached Scan Capture without clearing data or running disposable instrumentation over the operator.
+
+## Historical checkpoints
+
+Latest correction: hosted Android testing found revoked heartbeats remained successful. Approval now precedes all heartbeat activity observation, including accepted trailing-slash aliases. Independent red reproductions and final 37-root/four-demo green tests are retained; new hosted native verification remains pending. Scanner authentication must follow configured Authentik through explicit native semantic authentication metadata; that implementation and real-provider acceptance are now required release gates.
+
+The optional consumer has subsequently qualified frozen0515 with37 fresh base and18 integration tests, including the matched core logging correction and runtime integrity checks. This remains an isolated private candidate; immutable dependency publication and optional hosted CI are required before production adoption. Separate OAuth2 log-redaction work in the native-auth core branch is not included in0515.
+
+## Scope and checkpoints
+
+Latest verified checkpoint: server `0926550` includes the standalone file-backed presence regression and the passing browser-to-native
+viewing regression after guarded-upload commit `84ffd7c`. Base 37, demo HTTP two,
+browser 15 and optional guarded integration 18 cases pass. Android's local reports
+show 91 JVM tests; TC22 navigation (12 cases), orientation, offline licenses,
+synthetic camera/gallery/rotation/logout, and the complete real-screen/session-end
+scenario pass. Native photo/session requests match published semantic operations.
+The full server deep static security review of `0926550` is sealed with no reportable findings. It does not inspect external dependencies or production configuration and does not replace runtime acceptance. Android's full scan and the later single-hamburger UX correction remain pending.
+These are checkpoint results; final Android audits, fresh Android hosted CI,
+production provider/immutable dependency qualification and actual lens acceptance
+remain open. Signing/distribution is owner-deferred until the final step.
+
+- Server semantic baseline: `7dd02b8874882ca2edcdcd89109b3dee6b4b0c88`, with all hosted checks passing. Documentation checkpoint: `a49724384f569a4b4b66ce2cd4aa69332ee1e0e8`.
+- Android semantic baseline: `6574ec4991dbb859b60c3a0be462af96918aee32`; hosted JVM/lint/APK, CodeQL and CircleCI checks passed, but both hosted native E2E jobs failed at compatible login before any credential request reached the server. Login/form reachability fixes are under verification; this baseline is not fully green.
+- Active implementation: [device/session history, live activity, actual app screen viewing, session termination, identity/presence/location and Record Files integration](../DEVICE-SESSIONS.md).
+- Final audit scope: both complete repositories, including shared Android core/mobileapp libraries, scanner host, qbit, demo, build/release configuration, tests and documentation. Exclude local secrets and operator data from published evidence.
+
+## Required gates
+
+| Gate | Status / required evidence |
+| --- | --- |
+| Feature completion | Session administration, screen viewing and device naming/presence/location have passing server/browser coverage. Native navigation/session and Record Files photo integration are in progress. Actual ingestion routes exist; atomic revocation/commit protection and compatible runtime qualification remain open. |
+| Security | Independent multi-pass full scans of the frozen client and server; validate findings, fix release blockers, verify fixes and retain coverage/limitations. |
+| Architecture | Review boundaries, coupling/cohesion, session ownership, semantic API evolution, concurrency, resource limits and deployment assumptions. |
+| Coding standards | Repository conventions, public API compatibility, lifecycle/error handling, duplication, dead code and maintainability review. |
+| Automated tests | Unit, HTTP contract, schema/version compatibility, browser record/bulk processes and native UI-to-real-server tests on the final revision. |
+| Physical acceptance | TC22 capture, mirroring, remote logout, failure/retry, restart, data preservation, location permission/age, camera capture and gallery upload to an authorized record. |
+| Delivery | Release build, signing/update approach, reproducible artifacts, dependencies/licenses, secrets checks and final hosted CI. |
+| Operations | Supported deployment/database migration, HTTPS/authentication, retention/resource limits, diagnostics and recovery documentation. |
+| Final review | No unresolved release-blocking findings; evidence identifies exact revisions and remaining supported-use boundaries. |
+
+## Verified baseline evidence
+
+October 31 working-source evidence: 37 root tests, two real HTTP acceptance tests and all 15 browser E2E cases pass. Browser cases include single/selected-bulk/full-query session end, cancellation, live image/clear, device profile edits, location timestamps and online expiry/filtering. The full browser run completed in 59.4 seconds after correcting file-H2 connection lifetime. A subsequent virtual-online projection fix passes the 37-test suite; its combined native acceptance remains pending. Android's intermediate 76 JVM tests and zero-error/zero-warning lint pass; shared native and real-server session tests remain in progress. These are local intermediate results, not a frozen release or fresh hosted qualification.
+
+Server: 23 root tests plus the real HTTP lifecycle scenario and six packaged-frontend browser E2E scenarios. Android: 53 JVM tests, six shared native UI tests, lint with zero errors/six warnings, debug/E2E APK builds, and six semantic native scenarios across focused runs. The final admin scenario passed in 255.917 seconds; 31 of 31 requests matched 13 published operations, including cancellation. These results are baseline evidence and must not be represented as verification of later session/mirroring changes.
+
+Physical TC22 (Android 14, DataWedge 13.0.325, app 0.1.0): installed with existing state preserved, signed in and approved through the actual device-record process. A dedicated DataWedge profile uses barcode input, explicit broadcast delivery and package/signature verification, with keyboard output disabled. Two deliberate Code128 trigger scans produced two records. One QR trigger scan preserved `001234567890`; backend records confirmed symbology, source, user/device/app/process and timestamps. Outage/retry and remote-session controls remain to be tested on the completed feature.
+
+## Review findings
+
+The initial full-source architecture/maintainability review covered Android `6574ec4` and server `7dd02b8`; it does not cover the later session/device features. Findings are being remediated, with final independent review still required:
+
+| Finding | Remediation owner / evidence pending |
+| --- | --- |
+| A1: scan retry cleared on an incomplete receipt | Android host: require matching acknowledgement ID, `scanSaved=true` and nonblank scan ID. |
+| A2: invalid scanner length metadata silently defaulted/truncated | Android host: reject invalid or out-of-range metadata. |
+| A3: legacy INPUT_FIELD bypassed typed field semantics and interpreted input as action code | Shared client: typed field handling and explicit action capability. |
+| A4: ordinary asynchronous status failures lacked a safe retry | Shared client: retry status GET without replaying submission. |
+| A5: cancellation during initialization could leave a late process orphaned | Shared client: retain cancellation intent and cancel a returned process ID. |
+| A6: login/forms could place actions outside the viewport or behind the keyboard | Shared client: scrolling/IME handling and constrained-viewport native tests. Hosted failure cause remains unproven until the regression evidence is complete. |
+| A7: explicit null displayed a default while submitting null | Shared client: distinguish absent keys from explicit null consistently. |
+| A8: business JSON collided with class-based serialization envelopes | Shared client: ordinary JSON values without class loading. |
+| A9: multi-record mutations and enrollment could persist partially | Server: transactions for credential/device and session/binding pairs and bulk state changes; provider logout after durable tombstones with explicit cleanup outcome. |
+| A10: media ownership/disposal could leak resources | Shared client: sound/image lifecycle ownership. |
+| A11: navigation title/state and native back stack could drift | Android host: derive navigation state from the active NavController. |
+
+The completed TC22 session scenario delivered and decoded real application JPEG pixels, cleared background frames, renewed viewing on resume, honored operator Stop viewing, ended the session remotely and accepted a fresh login. Android packaging now verifies 130 notice entries, nine license texts and eight native binary hashes in each host variant. The full server static scan is complete; Android review, external core logging remediation/adoption, production signing/update path, supported database migration and final hosted checks remain required before 1.0.

+# Rich record preview — November 5
+
+Before this update, the maintained demo ran the earlier 198-test public RC.21/Printing 1.0 cohort. The first TC22 records/photo preview was installed in place with SHA-256 `79E6CD0559419E059EC253DD0364C13BDDB3C27F566F0DA9A478FBB70D99A038`; the user then clarified that the existing app and existing server should be used, without a separate manual QA application.
+
+The rich-record update added demo-only synthetic tables, ordinary metadata sections/associations, read-only permissions and explicit attachment grants. Native grouping and child queries use the versioned semantic API. Verification caught missing section tiers in metadata serialization and missing Origin headers in the composed-server test helper; both were corrected without weakening server guards. The final gate passed 189 tests and Android unit/lint/build checks. Isolated MC9400 native acceptance passed before adoption.

+The maintained database and objects were backed up; the server restarted with the new application JARs and the same owner dependency cohort.

+- **Scanner publication complete:** PR 12 merged normally as `286e2e0`; run 3645 succeeded. Anonymous Central readback verified the JAR, POM, sources and Javadocs for `com.kingsrook.qbits:qbit-mobile-scanners:0.1.0-20261103.233448-3645`. All 37 published Java source files match the reviewed source.
+- **Android publication complete:** PRs 10 and 8 merged into `main` at `0ae2101`. Main lifecycle 3634 succeeded; the shared CI owner's independent registry readback matched all ten primary files, including both AARs, at timestamp `0.1.1-20261103.232145-3634`. This publishes development libraries, not a signed production APK.
+- **Local runtime updated:** the server on port 57832 now uses public QQQ `4.1.0-RC.21` and released Printing `1.0.0`. The existing database and settings were retained. A fresh identity and health check confirms API `1.10.0`, mobile extension `1.5.0` and printing extension `2.3.0`. The normal TC22 remains signed in, shows Echo setup with Copies 1 and Connected; the existing Print Agent shows Connected and ready against this server. No physical print was submitted during this update.
+- **Exact updated cohort qualified:** 198 tests passed with no failures, errors or skips and Checkstyle passed. All 94 scanner Java inputs match reviewed source; all five QQQ backend dependencies resolve to public RC.21. Released Printing removes the three private QQQ transitive dependencies from the prior gate. Other document/files components still use qualified local owner artifacts.
+- **Echo Printing default implemented and reviewed:** both Echo POMs now select released Printing `1.0.0`; the dependency comment and READMEs match. Both modules pass Maven validation and Checkstyle. The version pin is the only semantic POM change, and all 94 Java files match the prior 198-test qualification. Remaining owner package versions are unchanged; normal source review/publication is next.
+- **Remaining source/publication work:** commit, review and publish the two Echo POM defaults for Printing `1.0.0` (prepared above), and obtain the document owner's coherent standalone Generation/bridges/Record Files/Scripting artifacts, including copies. The owner's website image pipeline does not publish these Maven artifacts. The owner verified that the local standalone directories are not Git repositories and have no release workflows; reviewed code lives in host candidate `b6fb238`, using private coordinates. The remaining work is source extraction with provenance, public dependency pins and standard standalone release wiring. No new domain feature is required for this publication step. Claude access is restored, and the dependency owner's actual Claude standalone packaging is active as of November 4; no claim of completion is made.
+- **Manual acceptance passed, operator reported:** on November 4 the user stated, "i have ran the manual tests - it all works". Accept this as completion of the outstanding manual acceptance group and do not request the same checks again. See [TC22 acceptance](../TC22-ACCEPTANCE.md). This is the operator's report, not a newly instrumented run or separate per-case evidence.
+- **Remaining scope/distribution decisions:** Echo's documented scanner profile still explicitly refuses unsupported GS1/ECI/binary variants; the manual pass does not add encoder support. Production Android signing and distribution remain deferred by the user.
+
+Evidence: local `qqq-scanner-published-3645/anonymous-readback.json`, `qrun-android-3634-readback/registry-readback-proof.json`, `qqq-printing100-echo-gate-20261103/verified-summary.json`, and the runtime pointer `qqq-public-core-printing-runtime-current.txt` under the user's cache directory.
+
+## November 3 — historical checkpoint
+
+- **Server source:** `45f9cbddb14999d28add02dd9a37e4ce018e282e` is signed and pushed on Gitea PR 7 (earlier "uncommitted" statements below are historical). The five `qqq.version` POM pins to public **QQQ 4.1.0-RC.21** (root, demo, Echo, Echo demo, record-files) and the record-files POM test fix below are included in this verified dependency update.
+- **Final RC.21 gate: PASS** (`C:/Users/james/.cache/qqq-rc21-copies-gate-076d059d8d0641d9a85874ec64008def/verified-summary.json`). 377 unique tests with zero failures, errors or skips and Checkstyle PASS: Generation 179 and Printing bridge 16 (`verify-recovery.log`); scanner 53, demo 8, mobile Record Files 18, Echo 68 and Echo demo 35 (`verify-consumers-junit-fixed.log`). Plus 15 real admin-browser E2E cases on public RC.21 (single, checked and query selection, first-N approve, revoke, end session, display name/description, location/online, screenshot widget). The three earlier MySQL network timeouts did not recur in the focused 31 or the full 179 runs; the original failure reports are retained.
+- **Owned source fix:** `integrations/record-files/pom.xml` drops the aggregate Jupiter 5.11.4 and uses the BOM-managed engine and params; the XML test classpath shows API, engine, params and platform all at 6.0.2.
+- **Dependency honesty:** the five owned scanner consumer modules resolve only public QQQ artifacts (core, rdbms, middleware, filesystem, openapi RC.21; frontend-next RC.35), and Generation's core is RC.21 too, so all 182 scanner-consumer tests use public QQQ modules. The 16 Printing-bridge owner tests still resolve three private `pu507` QQQ libraries (filesystem, Javalin, OpenAPI) transitively through the existing owner Printing POM, and the other owner qbits remain qualified private inputs. So: **377 pass with public core RC.21 plus qualified owner inputs; this is not a fully public or released cohort.** No normal-runtime core upgrade was performed.
+- **Generation copies:** canonical Git source is now `Website-Backend/third-party-src/qbit-document-generation`. Signed `aac68907e67906aeef4e0cd687d28bc98b738f8c` is pushed on `feature/echo-generation-copies`, based on the actual PR 343 head `8f473fa`. The isolated clone `C:/Users/james/.cache/qqq-generation-copies-git-20261103` has 13 paths (including the PostgreSQL migration and provenance); the 21/21 module manifest matches. Qualified: 179 Generation + 16 bridge tests (prior cohort) and a fresh real PostgreSQL 17 migration pass. Owner integration and public artifact publication are not acknowledged and remain pending. No peer active checkout was edited.
+- **Android:** `f72b90d08cf29d2785cef1d5c5e7eeaf75f9afd2` is signed and pushed to the existing AGit PR 10 head (read back independently over SSH). Gitea CI 3480 **succeeded** on it (unit-test, device-test, package, secrets, gate; root read the UI); root also verified a clean git merge-tree of f72b90d with actual `main` b75fdac and merged nothing. Pull requests #8 and #10 remain open; nothing is released. The updated normal APK (SHA-256 `4AAB6951D3B0ABDDD4F5A8DC6790DCD84233EE08179B68DB108BF77909AB850E`) is installed with the same signer and no data clear; Connected, Apps, Settings, portrait, location on and the system-wallpaper brand-only preview were verified. No wallpaper or profile was applied. Fresh: 222 JVM tests, lint 0 errors/0 warnings (2 info), APK builds, 23 Node tests, 255-file standards pass. A fresh disposable TC22 Echo ten-stage run passed 109/109 semantic requests (simulated inputs and printing).
+- **Authentik:** a fresh real desktop acceptance passed against the same isolated TLS fixture (nonce, A login, logout with old-cookie replay rejected, fresh B without clearing cookies, logout). The opt-in native harness is integrated and compiled and its 8 launcher guards pass. Native TC22 execution still needs the temporary CA and PIN interaction (pending); no trust bypass. The normal server on 57832 is unchanged and ready.
+- **Still open (not claimed):** Generation canonical owner integration and public reproducible inputs for the owner qbits; primary source CI, merge and release; the manual TC22 trigger, value/type, AIM, label count, rescan, photo, GPS, projection and profile checks (the operator is still remote); native Authentik CA, PIN and callback; and signing/distribution, deliberately last by user decision. The normal TC22 currently shows Echo setup, Copies 1, Connected.
+
+## November 3 — publication preparation (historical; superseded by the current checkpoint above)
+
+The scanner/Echo/demo sources for copies per scan, AIM/EAN/UPC fidelity and photo composition are in the working tree of `feature/echo-example`, ready for one signed commit and review (not yet committed). They declare no private artifact coordinates: Echo's POM states that copies need a Generation build with the print-copies change, and `integrations/record-files` now takes `qqq.version`, `mobile.version`, `recordfiles.version` and `collaboration.version` with the demo's defaults. The Generation copies change is ten hash-checked files; its eight existing files match the Kof22 release reactor's `third-party-src/qbit-document-generation` byte for byte (SHA-256 listed in `qqq-finish-server-ready-20261103.md`). No Git repository for Generation exists in these local directories: adoption belongs to the Kof22 release repository, so the change is a hash-verified file set, not a commit here. Nothing was built or pushed in this step.
+
+## November 2 — Echo copies adopted in the normal local server
+
+Optional **Copies per scan** defaults to 1 and accepts 1–100. Omitted/null/blank setup uses 1. The run pins the quantity; scan payloads cannot change it. Each scan creates one retained job with options.copies, with retries preserving quantity and job identity. Existing records migrate to 1. The normal server on port 57832 now runs this feature, mobile-scanners 1.5 and mobile-record-files 1.0 using the original database, approval, accounts and printer configuration. The unchanged normal TC22 APK is connected and shows the setup field with 1.
+
+Verified gates: Generation 179, Printing bridge 16, scanner 53, base demo 8, mobile Record Files 18, Echo 68 and composed demo 35 tests (377 unique tests across module runs, no failures/errors/skips). Native TC22 acceptance passed ten stages and 116/116 semantic requests, including default 1, range rejection, chosen 3 across two scans, recreation and Leave. Scanner inputs/printing are simulated; physical count remains unconfirmed. Android source also passes 222 JVM tests, lint and APK builds; 15 Node tests pass.
+
+Generation's ten-file copies contract is verified in C:/Users/james/.cache/qqq-generation-copies-20261102 with handoff qqq-generation-copies-handoff.md; canonical owner adoption/publication is still pending. Echo photo composition is running and its authorization tests pass; actual capture/upload is unqualified. Native Authentik and physical trigger/print/rescan, camera/GPS/projection checks are deferred while the operator is remote. No certificate installation is confirmed. Public coherent artifacts/CI and final signing/distribution remain open. Earlier checkpoints below are historical.
+
+## November 2 — current checkpoint
+
+Source candidate: mobile-scanners 1.5 adds optional `aimIdentifier` and exact SDK `rawDataBase64` to persisted scans and backend `scanContext`. Changed metadata on an existing event is rejected; identical retries retain the original row, and omitted metadata cannot leak from the preceding event. The generated semantic contract remains compatible with the unchanged 1.0, 1.1 and newly preserved 1.4 baselines. The isolated four-module reactor passes 135 tests (53 scanner, 8 native HTTP demo, 45 Echo, 29 composed demo), zero failures/errors/skips and Checkstyle clean. Independent Claude diff review found no actionable correctness, security or compatibility defect; a whitespace-only review correction followed verification. This candidate is not installed in the running demo; hardware AIM extraction and extended Echo fidelity remain open.
+
+The first actual Echo native HTTP event exposed a composition defect: Generation requested its default 20 MiB allowance from a renderer capped at 1 MiB. Both demo launchers now propagate their configured cap into Generation. Restoring the old wiring produces three regression failures; the fixed library/demo reactor passes all 74 tests (45 + 29), with no failures, errors or skips and Checkstyle clean. The preserving local server restart uses these tested artifacts. A new, clearly synthetic `ECHO-HTTP-TEST-001` Code128 event completed real rendering, retention and printing: one job reached `SPOOLED` with a spooler job assigned, and native Cancel closed the process. The earlier failed event remains `ATTENTION` without a print job and was also cancellable. Neither event is a physical TC22 scan. Paper output and rescan confirmation remain pending; see [delivery receipt](../../examples/echo/demo/docs/echo-delivery-acceptance.json).
+
+The real trusted-local renderer has produced Code128 `QQQ-TEST-123456` and QR `001234567890` from the actual published 4x1 revision. Independent ZXing pixel decoding and stock/margin/fit checks pass; a fresh native read confirms the same published revision and stock. See [rendering evidence and test images](../../examples/echo/demo/docs/ECHO-RENDERER-ACCEPTANCE.md). That earlier rendering-only check submitted no printer job; the subsequent synthetic delivery is recorded above. Physical acceptance remains open.
+
+The primary CI secret-scan failure was reproduced locally as five findings in inert test-token literals. The fixtures now generate tokens at runtime; `.gitleaksignore` names only the five exact historical commit/file/rule/line fingerprints. There are no rule or path exclusions and no production validation changes. Historical and staged Gitleaks scans pass, and all 27 composed demo tests pass with zero failures, errors or skips and zero Checkstyle violations. Current hosted CI still needs verification after publication.
+
+Completed and verified:
+
+- Server source `e3b775e` is signed and published as Gitea PR 7. The Echo library and composed demo pass 74 tests with zero Checkstyle violations. Host forwarding accepts `localhost` and `127.0.0.1` with a valid explicit port, and foreign Host and Origin values are denied.
+- One local QQQ demo server on host port 57832 runs Mobile Scanners/Echo, Collaboration/Record Files, Document Generation and Printing (API 1.10.0, mobile 1.4.0, printing 2.3.0). On this workstation, device port 8080 forwards to host port 57832. The original accounts, enrollment and approval are retained.
+- Android `fb3cc5d` (Gitea PR 10) adds the native same-origin fix. The normal TC22 was updated without clearing data, and existing login and approval, heartbeat, real printer, media and document selection, and Cancel then Leave were verified. The emulator is off because it stalls this workstation.
+- The installed print client (RC4) is signed in, enrolled and connected to this server, and its native-approved ZPL printer is available. The Printing owner has aligned the loaded 4x1 stock (101600 x 25400 microns at 300 dpi) and updated the real media revision. No UAC prompt or printer setup is pending.
+- A real Echo 4x1 barcode document is published through native authoring, with a matching immutable revision 1. The TC22 selected the actual printer, the fresh 4x1 media and that document. Next succeeded and the device shows Scanner ready and Connected.
+
+Not yet done:
+
+- No physical Echo print or rescan has been proven. The synthetic event has exactly one matching scan and one actual ZPL job in `SPOOLED`, rechecked at 16:31 UTC. The same read-only check confirmed server HTTP 200, print service Running, and the normal TC22 showing Echo / Scanner ready / Connected. One physical scan of QQQ-TEST-123456 has been requested from the user; no UAC or setup action is pending.
+- The earlier native end-to-end run (7 stages, 112 semantic requests) used simulated printing and inputs. It is not physical evidence.
+- Still open for 1.0: physical Code128 and leading-zero QR scan, print and rescan; the full original provider, camera, GPS, projection and device qualification; public coherent artifacts; primary Gitea CI; and final signing and distribution. Signing is deliberately last, by the user's decision. A working first demo does not collapse these requirements, and nothing here claims release readiness.
+- Core native API merge continuation PR 1337 (a42f9e5) was reviewed with no actionable conflict regression, and its 57 focused tests were verified. Normal CI and publication are not established, and default dependencies are not repinned.
+
+The entries below are historical. Where they describe same-origin login, printer connection, media, document publication or server composition as pending, this checkpoint supersedes them.
+
+## November 2 — one local QQQ server and installed print client connected
+
+The canonical local server on57832 now runs Mobile Scanners/Echo, Collaboration/Record Files, Document Generation and Printing together, using the existing development database. Both original accounts authenticated. Live discovery advertises API1.10/mobile1.4/printing2.3; authenticated administration metadata exposes the composed modules. This is greenfield local development: no backup, cutover or cross-server bridge is required.
+
+The full demo gate passes27 tests with zero failures/errors/skips and zero Checkstyle violations. It includes file-backed existing-data acceptance and the USB-forwarded loopback Host regression. Actual running HTTP checks accept Host127.0.0.1:8080 through57832 and reject foreign hosts/origins. The TC22 retains its original app data, approved device and8080 USB connection; no emulator runs.
+
+The existing RC4 print client is now natively signed in, enrolled and connected to57832. It reports five printers/two exposed. The sole available ZPL printer was approved through the ordinary printingEnablePrinter process; the persisted native query confirms enabled/available. No physical job was sent and printer defaults were unchanged.
+
+(Superseded by the current checkpoint above: the same-origin header, 4x1 media report and document publication are done. Only the physical TC22 scan, print and rescan remains for the demo, and the full production release gates remain open. Earlier separate 53118 pairing and Windows-prompt status below are historical.)
+
+## November 1 — corrected setup verified on TC22 and published
+
+Server source8da274e and Android test-only source47a923a are signed/pushed; Android's actual Gitea PR10 review topic was advanced to47a923a via SSH AGit (the source feature branch alone does not advance an AGit review ref). Required printer/media/INTEGER Document selection, dependency clearing, two accepted synthetic scans with the same selections, recreation and Apps/Leave all passed on real TC22:7 stages,112/112 published semantic requests,15 operations. Normal app/data preserved; emulator off; printing/scanner qualification flags remain false. Server45/library24/demo and Android99focused/host tests+8Nodeguards/lint0errors0warnings pass. Live private server53118 is still101efc8/EchoRetry pending document-choice rollout, and actual printer pairing awaits the current Windows consent in existing session73437. No root physical print has occurred. Normal57832 stays unchanged.
+## November 1 — operator chooses the Document at setup (server verified)
+
+User-confirmed flow: choose printer, Document template and paper/label size once, then repeat scan -> server render -> accepted print job until Leave. The Android client remains a generic semantic QQQ process client; it has no printer-device integration. `templateId` is required INTEGER with an authorized dependent PVS, not a hidden server default. The run pins selected template/revision; changed documents are refused rather than substituted. Migration preserves existing rows. Root:45 Echo library/24 full composed demo tests PASS, Checkstyle0. Tests include two document choices, forged retarget refusal, republish refusal with native Leave/CLOSED and repeated scan rendering. Expected errors use existing output.setException to retain process ownership after core step failure. Native Android tests99 + Node8 + lint0errors0warnings/testAPK compile pass; updated TC22 UI acceptance remains in progress. No physical print claim. Private live53118 remains filtered source101efc8/EchoRetry until this rollout, and printer retry awaits Windows consent; normal57832/TC22data are preserved.
+## November 1 — shared device headers scoped per extension registry (verified)
+
+`MobileScannersRouteProvider` interpreted every `X-QQQ-Device-*` header as a scanner credential, so a native Printing agent's own proof got 403 on `/qqq/v1/qbit/printing/*`. It now leaves a request to another extension's own authenticator only when the path is another extension's `/qqq/v1/qbit/*` route (not scanner routes, metadata, process or widget calls) and QQQ already validated a registered, non-`android`, non-`web`, non-token client channel. Android and unmarked requests keep scanner verification everywhere, ended-session and approval checks are unchanged, and no scanner device is bound for the foreign route, so the marker grants nothing. New composed demo regression `printerDeviceProofIsAuthorizedByPrintingAndNeverByScannerAuthentication` passed against the new immutable private scanner artifact. Root verification:50 scanner tests,7 base-demo HTTP tests and23 composed Echo-demo tests, Checkstyle0. The corrected regression fails403 at printer binding on the old artifact and passes on the fixed artifact; wrong proof/actor and scanner-boundary denials remain enforced. Live update and physical printing are separate.
+
+## November 1 — independent review corrections verified
+
+The scoped independent review of Echo4bc88a4/Androida2f0080 found a pre-pin recovery gap, an unchecked atomic pin result and a late-revocation receipt-audit gap. The fixes preserve authorization checks and lookup-only recovery after a pin. Five meaningful regressions now pass: Echo38 and full composed demo22, Checkstyle0. See ECHO-RELEASE-REVIEW-2026-11-01.md. The running private backend remains on the earlier qualified Echo artifact until an owned rollout; no running SDK or normal operator database was overwritten. Physical print/rescan and public release gates remain open.
+## November 1 — Echo composed pipeline verified and private backend live
+
+Echo's 33 tests and the runnable demo's full22 tests pass with zero failures/errors/skips and Checkstyle0. The clean native HTTP acceptance uses the real Generation, Record Files and Printing owners: two scans create two retained originals and two accepted jobs; retry preserves one job, and Leave closes the run. Renderer output is controlled and printer inventory simulated in this test, so physical printing remains unqualified. The Echo source checker now accepts core's exact bare READ capability probe while preserving user/permission checks, actor row locks and concrete write denial. The demo enriches complete QQQ metadata, establishes attachment capability, and derives the printing tenant idempotently. Host tests reset JVM-local RDBMS providers between fixtures.
+
+The local launcher uses the renderer owner's explicit TrustedLocalDockerExchange public factory (unique private renderer0.1.0-echo.gen64c9pu507.tl1); no copied transport or production fallback remains. Owner52 tests and real Docker smoke qualify development use only. A fresh private instance is live with successful scanner/admin semantic login and metadata; no printer or template is configured yet. Normal operator data/runtime remain preserved.
+
+Next required path: native Windows printing connection/current4x1stock handoff, publish and pin a real media-matched template, actual TC22 scan/print/rescan, and primary Gitea CI/public dependency publication. Full1.0 physical provider/GPS/photo/screen gates and broader AIM/EAN/UPC/GS1/raw barcode fidelity remain open. Production signing/distribution is deferred as requested. Passing private SDK/source gates is not a production release claim.
+## November 1 — coherent scanner and Record Files regression verified
+
+Security-key snapshots compare effective membership as sets, allowing identical repeated grants and reordering while rejecting new or changed authority. Optional Record Files authentication applies the owner's CollaborationSecurity.applyToSession during login/revalidation before the first verified capture. Scanner50 and native Record Files18 (16 integration +2 contract) pass with zero failures/errors/skips and Checkstyle0 against the complete private gen64c9pu507/PU dependency cohort. This supersedes the prior pending/failed native18 checkpoint; it does not declare private dependencies published or production-qualified.
+
+Echo32 and runnable demo12 also pass on that cohort. The demo startup test uses a refusing renderer; actual live cold renderer configuration and physical print/rescan remain pending. Android169 JVM and five-stage TC22 native semantic Echo acceptance passed with simulated printing. Gitea is primary for further source publication; previous GitHub PR links are historical shadow references. Preserve the normal scanner/server/data and printer installation. Signing/distribution remains deferred.
+## November 1 — verified capture identity retained without authority drift
+
+Claude's scanner fix preserves the same already-verified session only after current approval/binding/authentication and unchanged session reference/authority checks. First capture still wraps. Tests cover repeated object identity, current permission/credential ceilings/selectors, device and user binding, revocation, and real post-query-hook mutations during validation. Mutable opaque authority values refuse retention. Full scanner49 and real demoHTTP7 cases pass with Checkstyle0 against the frozen privatePU/f708 core.
+
+The files owner still must qualify its strict native upload/finalize18 against this exact patch; no per-instance enrichment policy or global registry is adopted. Normal server/data remain unchanged. Echo native TC22 now passes all5stages/86documentedrequests with client3bec46d; real renderer/printer output and final host integration remain open. Production signing is deferred.
+# QQQ Mobile Scanners session state
+
+## November 1 typed scan context implementation
+
+Extension 1.3 defines accepted `scanContext` for backend actions, preserving exact symbology and server-derived attribution. Legacy omissions are explicit UNKNOWN/MANUAL; event inputs are consumed, changed retry types/apps/processes are rejected, and pre-context state requires reopening the process. The default scanner loop remains while appended host steps can consume context. Qualified private API 1.10 verification passes 44 root, seven real-HTTP demo and 18 optional integration tests with normal Checkstyle; canonical contract generation passes two additional tests and preserves both release baselines. The source cohort is `qqq-server-typed-context-843fa0ee69b34535b1890cf7347492ee`; no normal runtime adoption is implied.
+
+## Echo implementation scope
+
+User requested example QQQ application Echo: first select printer and paper/label size, then continuously scan → render the same value/symbology → print until leaving. User chose one in-flight job and delegated first real printer/media choice to the printing master. Team implements the optional examples/echo host, ordinary semantic QQQ process metadata and server per-scan context; no new Android screen engine, barcode encoder, attachment framework or print queue.
+
+Owner coordination requests are posted in our shared mailbox. Source discovery found missing authorized media discovery/job options, worker barcode fit-to-stock, least-privilege printing submission and an immutable retained-print adapter handoff. These are concrete integration gates, not permission to change the other masters' source or live printer/service. Implementation and isolated tests can proceed while owners respond; no physical print or final working Echo claim yet.
+
+## November 1 standards implementation and API 1.10 qualification
+
+Copyright/SPDX, member layout and optional PowerShell tooling fixes are applied. Unexpected server failures now produce fixed structured diagnostics without private values. The attachment test fixture closes its metadata-before-stream ownership gap. Fresh Checkstyle/compilation, 39 root tests and six real HTTP tests pass against the qualified private API1.10 cohort; optional integration verification is tracked in the standards review. These are source gates, not a normal-server deployment.
+
+Core native API1.10 is signed and published as e1e45b29f in draft PR1369. Its real Authentik fixture is upgraded and actual retained-browser account switching is under test. Android1127 is published; the installed normal APK is the diagnostics/location3fee build, preserving sign-in and data. Prior installed1c Code128, leading-zero QR and menu/reopen were physically confirmed. Default-on location, existing fine/coarse grants and system location are verified; an actual GPS fix remains open. Historical entries below retain their original scope. See [standards review](../CODING-STANDARDS-REVIEW-2026-11-01.md).
+
+
+## November 1 provider logout implementation in progress
+
+Core32 passes all ten hosted checks, including corrected1000-test sample acceptance; Android8d8 passes all eleven checks. The final coherent core32/scanner1a3 cohort passes39 scanner/six demo/18 Record Files/15 browser cases and is recorded in the published qualification document.
+
+Real Authentik now passes a desktop-browser PKCE callback through the native-session exchange contract, principal A, QQQ logout and old-cookie rejection. This does not establish Android external-browser acceptance. A subsequent login with provider SSO retained silently reused A despite prompt=login. The pinned provider also ignores max_age=0. This is an open operator-handoff issue, not a passed two-operator test. Optional standard RP-initiated logout is being implemented in core branch feature/mobile-native-provider-logout (based on core32) and the Android client, with explicit API1.10 capability, encrypted session-bound hint storage, local logout independent of provider failures, and a separately correlated AppAuth end-session attempt. The user policy choice (automatic company sign-out versus retained SSO with account confirmation/Switch account) remains pending; default sign-out behavior has not changed.
+
+The optional Android provider-logout working patch passes148 JVM tests, lint and debug build; native cases compile but have not run. The first isolated core package failed at an UpdateOutput API mismatch before tests. Independent review also found the optional hint gate must reject alternate in-process/code-state authentication sources; corrections and an HTTP regression are in progress. Initial failed candidate evidence is preserved.
+
+The isolated localhost-CA E2E APK built from signed Android8d8 passes63 unit cases/zero lint errors and packaged CA/callback/signature inspection. It is not installed; no device trust changed. Normal TC22 remains portrait C891 and its API1.9/mobile1.1 server remains untouched. Current QR, camera/gallery, projection, GPS and failure/navigation operator acceptance remain open. Files-owner immutable handoff/default adoption and final signing/distribution remain separate.
+
+Updated: 2026-11-01
+
+## November 1 release reconciliation
+
+Published server1041693 retains its qualified source-pinned API1.9/mobile1.2 server/demo/browser/provenance evidence. Android portrait-default7de passes all eleven hosted checks; QR documentation2e0fd962 does not establish physical QR acceptance. The normal runtime remains coreecf/serverb14 API1.9/mobile1.1 on57832, with normal portrait-default C891 development APK installed preserving signer/data. Trusted EMDK Code128 evidence comprises eight priorF3AF events and oneC891 event; QR, lifecycle/ownership and failure/retry/leave operator paths remain pending. Whole-device1.2 is qualified source, not installed normal-server behavior.
+
+Filesystem portability passes142 discovered/138 passed/four existing skips, including the corrected invalid-reference exception contract; its metadata symlink-parent and NUL-reference findings are independently closed. The final coherent core32/scanner1a3 cohort passes78 consumer cases, including18 Record Files cases, with no separate filesystem override. Matching files-owner immutable/default adoption remains open. Actual Authentik flow remains pending; strict proxy TLS now works, while provider configuration returned a validation error under diagnosis; physical projection, camera/gallery and GPS acceptance remain open. Signing/distribution stays owner-deferred until the final step. [PRODUCTION-READINESS.md](../PRODUCTION-READINESS.md) is the current matrix; older entries below retain historical scope and are superseded where their then-open state has changed.
+
+Cross-chat coordination uses `R:\agent-comms\README.md` and the mobile master's owned `R:\agent-comms\qqq-mobile-scanner.md`, explicitly requested by the user. Record Files and Printing acknowledged the directory. Read the current summary at the top of each owner's mailbox before changing shared contracts.
+
+## November 1 Record Files consumer checkpoint
+
+The isolated core32/scanner1a3 cohort passes all 78 consumer cases (39 scanner,
+six demo HTTP, 18 Record Files and 15 real-browser process tests), with coherent
+backend versions, 214 optional runtime JARs and zero duplicate QQQ/QBit classes.
+Core verification combines the prior full reactor gate, the corrected filesystem
+full gate and an exhaustive final artifact class comparison; see the precise
+[qualification scope](../../integrations/record-files/docs/CORE-32DF-CONSUMER-QUALIFICATION.md).
+The files-owner matching immutable handoff, optional default adoption and actual
+camera/gallery acceptance remain open. This cohort did not change the normal
+runtime, device or historical optional default.
+
+## October 31 current checkpoint
+
+The normal local demo is now running the qualified `ecf0f550`/`b14d925` API1.9/mobile1.1 TABLE runtime at its existing loopback address. This supersedes the unchanged-runtime statements in the historical acceptance entries below. Read-only inspection froze its actual old classpath; old-runtime and old-after-new HTTP/login checks passed on historical and fresh closed backups before startup. Fresh copied invariants preserved every original column, row count, password/device-credential hash, barcode and UTC timestamp. Both original accounts passed live login, authenticated metadata and logout; ordinary semantic queries confirmed two devices and three scans, including the leading-zero barcode. The normal Android installation and peer services were preserved. Private backup/runtime evidence is retained in the task cache; old PID-specific maintenance helpers must never target the replacement JVM.
+
+Optional consent-based whole-device viewing is under implementation as an additive extension1.2 contract; it is not part of that running, qualified1.1 runtime. Android diagnostic checkpoint `6f25562` is published to its existing PR after instrumentation compilation; fresh hosted results remain pending. The actual trusted-scanner trigger attempt is unverified. Production signing/distribution remains the final owner decision.
+
+The initial1.2 reactor now passes39 server and six real-HTTP demo tests with normal Checkstyle, no failures/errors/skips, unchanged qualified-core hashes and unchanged1.0/1.1 baselines. Independent changed-file source review found no concrete introduced security finding; Android consent and projection acceptance remain open. The diagnostic Android checkpoint subsequently passed CircleCI37 native tests and unit tests; its earlier intermittent focus-owner cause remains unproven.
+
+Exact-source core `ecf0f550a0357cec6387c2b54efca128a405a629` with server `b14d925b741e815d1cfa4f62301f19207f25b03f` now passes fresh37 server/five demo tests, strict runtime provenance and all15 browser cases (zero skips/flaky/failures). The runtime has195 hashed JARs,2,440 unique QQQ classes, zero duplicate QQQ classes, patched Guava33.7.2-jre and H2 2.2.224. Core's full selected closure separately passes4,507 discovered/16 existing skips/zero failures/errors. See [qualification scope](../API19-CONSUMER-ACCEPTANCE.md). No operator runtime was upgraded by this acceptance.
+
+The demo now imports the QQQ BOM using its own `qqq.version`, so an explicit version selection governs its complete transitive QQQ runtime. Private source qualification caught the prior mismatch: the scanner's installed POM retained its default RC.20 property, while the demo override selected a newer direct RDBMS dependency. The strict runtime verifier rejected the mixed core/Javalin/OpenAPI versions and older Guava despite passing tests. The first BOM-aligned run then exposed the demo's explicit JUnit 5.11.4 aggregate mixing an older API with the BOM's JUnit 6 engine; the demo now uses the BOM-managed test engine and its matching API/platform. The coherent candidate's fresh acceptance is recorded above; passing tests from the earlier mixed runtime did not establish that result. No operator runtime or shared Maven repository was changed.
+
+The normal operator demo was upgraded in place to mobile extension1.1 with a closed owner-only backup: two accounts, two devices (one approved), three scans, credential hashes and timestamp instants were preserved. Both original passwords authenticated after startup. Its JVM currently uses UTC because the copied upgrade exposed H2 converting legacy zoned timestamps using the workstation zone. The canonical H2 schema now begins by setting its migration connection to UTC, protecting both direct schema consumers and the demo initializer. A no-install reactor verifies the freshly packaged base resource: 37 base tests and five demo tests pass, with zero Checkstyle violations, including a file-backed America/Chicago child-JVM regression over all eleven converted timestamp columns, multiple source offsets, preserved passwords/approval/barcodes and an idempotent second startup. The isolated old-schema resource without the UTC statement fails with the expected six-hour winter timestamp shift; the tested jar resource hash matches the canonical source. This source change does not restart the operator runtime; it remains safely mitigated with UTC.
+
+The optional Record Files consumer now explicitly defaults to frozen0515 and its separate isolated-m2-0515 cache. Fresh normalized-heartbeat base37 and optional18 pass, with214 runtime jars/3180 classes/zero duplicates. Immutable evidence is retained under integrations/record-files/evidence/20261031-124632Z. Earlier0352 native acceptance remains historical;0515 is a new server consumer qualification, not an operator upgrade. Published dependency coordinates and hosted optional CI remain blocked on the upstream handoff recorded in HOSTED-CI-DEPENDENCIES.md. New API1.9 native Authentik metadata is being developed in an isolated core worktree and is not part of this server's adopted dependencies.
+
+Hosted Android acceptance exposed a heartbeat revocation defect after the published checkpoint: pending/revoked devices could keep receiving successful heartbeats and remain signed in. The fix checks approval under the existing activity lock before observing activity, and the route filter avoids pre-observation for canonical and accepted trailing-slash heartbeat paths. Both defects were independently reproduced before correction. Final root verification/install passes 37 tests and demo verification passes four tests, including the real HTTP no-side-effects regression and standalone presence case. Native hosted confirmation on the new server revision is still required; earlier static zero-findings results do not prove absence of this defect.
+
+Server checkpoint `0926550` includes 37 passing root tests, two HTTP acceptance cases, a passing standalone file-backed presence regression and 15 passing browser cases. The optional Record Files module adopts frozen bundle `retained-contract-20261031-0352`; 18 guarded integration/contract tests pass. TC22 navigation (12 cases), orientation, offline licenses, synthetic photos and the complete screen-viewing/session-end scenario pass on Android checkpoint `d5b5580`. These do not imply an operator-runtime upgrade or actual camera-lens acceptance.
+
+The full server deep static security scan of `0926550` completed and its canonical report was sealed on October 31 with no reportable findings. Coverage excludes external dependency implementations and production configuration; no new runtime tests were executed by the scan. The known external core DEBUG session logging issue, immutable Record Files publication/CI and production provider qualification remain open. Android's final full scan is still pending. A user-requested single-hamburger navigation correction is now being implemented after the published Android checkpoint; its new tests are not yet run.
+
+The normal operator demo and normal TC22 package remain unchanged. A separate temporary visual demo showed the new menu on the TC22; the user stopped computer control and retains the device. Do not restart, uninstall or drive that demo until coordinated. Signing/distribution remains deferred to the final step.
+
+The local emulator is closed after the user confirmed it caused workstation-wide stutters. TC22 is connected; do not restart the emulator automatically. Builds are serialized with bounded workers. Existing operator demo and handheld state remain preserved. Android85 JVM tests and zero-error/zero-warning lint pass at the last compiled checkpoint; newer changes must be verified again.
+
+The active goal authorizes completing and publishing the project, superseding historical artifact-publication deferrals below. However, on October31 the owner explicitly deferred signing and distribution until the final step because the channel is undecided. Complete implementation, final audits, tests, documentation and ordinary hosted CI first. No signing key, production release, merge or deployment is claimed.
+
+## Active: device sessions, live screen viewing and 1.0 audit
+
+Additional user scope: unique short device names assigned at setup/approval, editable names/descriptions, independent approval/presence, online fleet view and foreground GPS with age/accuracy. Camera/gallery photos use the separately developed Record Files qbit. The Build QQQ Documentation agent owns it and `qbit-record-files/docs/INGESTION-CONTRACT.md` documents the implemented record-files1.0 semantic capabilities/create/status/chunk/finalize/cancel operations and durable receipts. The October31 checkpoint above supersedes earlier proposed-only contract status. Native photo acceptance and the final authorization guard remain pending; unavailable capabilities stay hidden.
+
+The user requires all device/session history, live activity and actual application-screen viewing in QQQ administration, plus session termination. Implementation follows [DEVICE-SESSIONS.md](../DEVICE-SESSIONS.md): ordinary QQQ tables/widgets/processes, server-owned authenticated bindings, an additive 1.1 semantic extension and demand-based bounded screen frames. Native and browser actions require full E2E coverage, including record and bulk entry points.
+
+The user also requires independent in-depth security, architecture, coding-standards and coupling/cohesion reviews of both complete repositories before a production-ready 1.0. [PRODUCTION-READINESS.md](../PRODUCTION-READINESS.md) tracks the gates and exact baseline evidence. Plan: complete the session feature and tests; freeze final revisions for independent audits; remediate and verify findings; complete physical and release/operations acceptance. Deployment/distribution details have been requested. No 1.0 readiness or release is claimed.
+
+## Current: semantic API migration
+
+The qbit registers mobile-scanners 1.0.0 through QQQ's extension registry. Device enrollment/current status, branding and connectivity use `/qqq/v1/qbit/mobile-scanners`; discovery advertises the relative prefix `/qbit/mobile-scanners`. The generated OpenAPI includes typed device and scanner event/acknowledgment schemas, stable operation IDs and standard errors. Legacy standalone mobile routes are removed. [UI-API.md](../UI-API.md) describes the contract and versioning policy.
+
+Root `verify install` passed 23 tests, including the extension contract baseline checks; demo `verify` passed one real HTTP discovery/schema/error/lifecycle scenario. All six migrated browser E2E scenarios passed in 2.9 minutes. Native integration exposed an unregistered Android client channel returning HTTP400; the qbit now registers `android` without replacing existing channel policies. The real HTTP regression sends `X-QQQ-Client: android/qqq-mobile` on all requests and passes. Android requires `android` in discovery's `clientChannels`; its combined JVM suites passed 53 tests (core 21/mobileapp 23/scanner 9), with six shared native UI tests also passing. Final lint passed with zero errors and six warnings; debug and E2E APK builds passed. Five native scanner scenarios passed with the OpenAPI request audit: incompatible core version, missing extension, missing Android channel, baseline scan flow and additive future metadata. The final native administration form scenario passed in 255.917 seconds after correcting completion handling for a COMPLETE response without `nextStep`: approval, revocation and cancellation completed, with all 31 requests matched to 13 published operations. All six native scenarios passed across the original and focused reruns; this is not a claim of one uninterrupted six-case run. All hosted checks passed for published server commit `7dd02b8874882ca2edcdcd89109b3dee6b4b0c88`: CircleCI setup/verify, CodeQL, Windows helpers and the demo HTTP/browser E2E job.
+
+Active plan: publish the companion Android checkpoint pinned to verified server code `7dd02b8`, then add the requested device/session activity, session termination and on-demand app-screen viewing. Physical connection-loss/retry and revoke-denial checks are deferred to acceptance with those session controls; the persistent server and USB forwarding are restored. The local server and emulator restarted after the workstation crash with data preserved; the backend administration UI was visibly signed in. The physical TC22 is identified through authorized USB debugging, running Android 14 and DataWedge 13.0.325. The debug app is installed and signed in. Approval from the browser record's Actions menu visibly reported one device approved; the handheld then opened the native app catalog and Scan Capture process. Updating the APK preserved its login. DataWedge is configured for package `io.qrun.mobile.scanner`, activity `*`, barcode input enabled, keystroke output disabled and Intent Output enabled. Intent delivery uses Broadcast, action `io.qrun.mobile.scanner.SCAN`, category `android.intent.category.DEFAULT`, and an explicit target package with signature checking enabled. Two deliberate physical trigger presses were confirmed by the user and produced two persisted records visible in Barcode Scans. A stored row matched the TC22 receipt for `QQQ-TEST-123456`, CODE128, source `scanner`, user `scanner`, TC22/Android 14/app 0.1.0, app `mobileScanApp`, process `mobileScanCapture`, and capture/receipt timestamps. Basic physical Code128 delivery and persistence passed. A subsequent physical QR scan was acknowledged on the handheld and independently visible in the backend as `001234567890`, `LABEL-TYPE-QRCODE`, source `scanner`, with matching TC22/user/app/process and capture/receipt metadata. Three physical records are verified: two deliberate Code128 captures and one QR capture. Physical QR delivery and leading-zero preservation passed; physical connection-loss/retry and revoke-denial checks remain pending. The old semantic-gap note below is superseded by this implementation status and the current TODO.
+
+## Verified: record and bulk device administration
+
+- User reported Approve Device did not work from a device record and required proper E2E coverage for every process, including single-record and bulk entry points.
+- Root and real HTTP regressions reproduced the missing selected device ID. Approval/revocation now prepare a stable selection, show confirmation, apply only after confirmation, and display a result/count. Explicit selected IDs and native select-all/first-N filters are supported up to 100 devices; oversized selections fail explicitly.
+- The process stores selected IDs in native process records, ignores replacement IDs submitted at confirmation, rechecks administrator permission, and validates all targets before changing any. Standalone manual ID entry remains supported.
+- Root verification/install passed 21 tests and Checkstyle. Demo verification passed the real HTTP scenario covering single-record approval, both bulk selection modes for approve/revoke, unselected-device isolation, visible results, scanner permission denial, scan persistence/retry, and revoked-device denial.
+- Restarted the persistent local demo on port 57832; public status returned `ok`. Accounts, database and emulator forwarding were preserved. Dedicated scanner-host native E2E passed (one complete real-server scenario, 50.932 seconds); Android verification also passed 28 JVM tests, lint/build and workflow syntax. Test APKs were removed and the normal scanner restored.
+- Browser E2E passed all six scenarios in 2.7 minutes: record approve/revoke with results and return navigation, checked-row bulk with untouched-device assertions, standalone manual entry, cancellation, full-query selection, and first-N selection with independent persisted-state checks. Tests use the packaged frontend and a temporary real backend. The fixture authenticates through the real API and supplies the nonsecret `qqq.sessionHint` marker so the UI resumes and validates its HttpOnly cookie. Browser checks now run inside the existing required demo CI job; native E2E runs in the Android push/PR emulator lane. New-head hosted results remain separate from these local passes.
+- UI/UX API clarification: the Android app uses `/qqq/v1` metadata/process operations, but full semantic-client conformance is unfinished. Version/feature negotiation, broader native component handling and migration of separate `/mobile/v1` routes into a registered UI API extension are tracked in TODO; do not describe the current client as fully conformant.
+
+2026-10-30 correction: native authentication metadata is served at `/qqq/v1/metaData/authentication`. The device-header guard now exempts that exact public path; the previous legacy-only exemption caused HTTP403 on app restart after enrollment when device headers were present before a user session was restored. A real HTTP regression failed before the fix and passed afterward with stale, pending, invalid-token and revoked device headers. Protected metadata/process/scan authorization still fails appropriately. Root13 tests, Checkstyle and demo HTTP acceptance passed; the local demo was restarted on57832 with its persistent database and accounts preserved.
+
+## Current repository and demo state
+
+- GitHub repository created at https://github.com/QRun-IO/qbit-mobile-scanners with `develop` as default. Initial signed commit `abbcc39` is published. Companion Android implementation is in https://github.com/QRun-IO/qqq-android/pull/8.
+- Hosted initial-commit checks passed: CircleCI `setup`/`verify`, CodeQL `analyze / Analyze branch source`, demo HTTP acceptance and Windows helper analysis. CircleCI dynamic configuration is enabled. Maven artifact publication remains disabled.
+- Runtime branding is configurable on the server before login; the shared Android APK uses the customer name, primary color and optional HTTPS logo. Public branding/status endpoints carry no credentials. Root tests now pass 13 cases; demo HTTP acceptance also passes.
+- Windows demo helpers store generated demo passwords using per-user Windows DPAPI outside the repository. An Android 15/API35 emulator is running with WHPX; six native UI instrumentation tests passed. Physical TC22 acceptance is still pending.
+- The current workstation demo uses loopback port 57832 because other services occupy the conventional ports. `adb reverse tcp:8080 tcp:57832` preserves the Android server URL `http://127.0.0.1:8080/`. Start it again with `pwsh -File scripts/Start-Demo.ps1 -SkipBuild -Port 57832` after stopping the existing instance. See `LOCAL-DEMO.md` for login helpers.
+- The earlier verification/handoff notes below describe the initial implementation before repository publication and emulator setup.
+
+## Confirmed scope
+
+- Native Android host for Zebra TC22 and other handheld scanners, extending `qqq-android`.
+- Server-defined native screens and QQQ process actions, using existing QQQ metadata.
+- Online only for version one; no offline scan queue.
+- Local demo server with real QQQ login and required administrator device approval.
+- First app: barcode capture into a QQQ table with scan, user, device and timestamp metadata.
+- User authorized Codex agents for implementation and subsequently requested GitHub repositories and standard project files. Repository creation and pushes are authorized; artifact publication remains disabled.
+
+## Completed plan
+
+1. Established enrollment and scan contract using existing QQQ APIs.
+2. Implemented qbit tables, native metadata/processes, approval/revocation and guarded routes.
+3. Added Android scanner host, table-based login/enrollment gate and Zebra DataWedge input.
+4. Added a file-backed H2 demo and verified native login, approval, scan, retry and revocation over HTTP.
+5. Built the Android debug APK and documented TC22 hardware acceptance.
+6. Added standard repository/community files, current shared CircleCI QBit configuration, CodeQL, Dependabot, demo HTTP and Windows-script CI, and a documented publishing policy.
+
+## Baseline and ownership
+
+- QQQ baseline: 4.1.0-RC.21 (public Maven Central; adopted 2026-11-03, gate pending). The local 4.0.0 middleware does not support Basic sign-in through `manageSession`; RC.20 and later do.
+- Backend agent: qbit main source, unit/integration tests and root POM.
+- Android agent: `qqq-android` source and scanner application module.
+- Toolchain agent: Android SDK installed after explicit user approval of required Google terms.
+- Parent: local demo, cross-component verification and documentation.
+
+## Verification
+
+- Qbit: `./mvnw.cmd -q verify install` passed 11 tests (7 H2 behavioral/security tests and 4 inherited guardrails), with Checkstyle passing.
+- Demo: `../mvnw.cmd -B verify` passed Checkstyle and one real HTTP acceptance scenario. It verifies QQQ login, anonymous and pending-device denial, operator/admin separation, approval, async native process capture, same-event deduplication, SQL provenance, bad/missing device credentials, revocation while a process is open, logout and session replay rejection.
+- HTTP fixtures verify the actual native `composite`/`SCANNER` widget payload. The Android tests deserialize these real metadata/process/init responses.
+- Android: core/mobileapp/scanner JVM suites passed 19 tests, no failures or skips. `lintDebug` and `assembleDebug` passed. Lint has 0 errors and 5 warnings: 3 inherited Navigation custom checks skipped due to API incompatibility and 2 dependency/version notices.
+- Debug APK signature verified. Path: `../../qqq-android/scanner-host/build/outputs/apk/debug/scanner-host-debug.apk`.
+- APK SHA256: `B3E160CE3279C369CEDB425AC6E777A2729CE8A2E430E7D6F46D35C6376F8214`.
+- Android SDK location: `C:/Users/james/AppData/Local/Android/Sdk`; SDK 35, build-tools 34/35, Gradle 8.7.
+- `adb devices -l` returned no attached devices. No physical TC22, camera, or emulator acceptance performed.
+- Repository bootstrap verification: CircleCI setup validated against the private QRun-IO orb with explicit organization scope; Actionlint passed for both workflows. Current shared generator accepted the manifest and selected verification only for seven branch/tag cases. All publication switches are false. Root 11 tests and demo one scenario were rerun successfully after repository metadata changes.
+
+## Handoff and remaining scope
+
+- Follow `TC22-ACCEPTANCE.md` for local credentials, loopback demo, USB forwarding, DataWedge profile and device tests.
+- Runtime demo server is not left running. No user credentials were created outside temporary test databases.
+- First host supports QQQ table-based authentication; other providers show an explicit unsupported message pending configuration.
+- Server enforces approved device plus authenticated user, including async execution. Enable QQQ core permission enforcement when embedding the qbit.
+- Only a current unacknowledged scan is retained in memory for explicit retry. Closing/resetting the app is not an offline queue.
+- The H2 schema is supplied; migrations for other databases and deployment authentication remain host-owned.
+- Pending physical acceptance is tracked in TODO. GitHub bootstrap and hosted checks are separate from artifact release or production deployment; use `CI-CD.md` for the repository settings and release enablement policy.
+
+## Native authentication review follow-up
+The first optional provider-logout compile failure and alternate authentication-source hint gate are corrected in a new frozen source candidate; its isolated focused build is running. Independently, native login does not currently carry/validate the original request nonce against the provider ID token. PKCE code binding is present; no account-takeover exploit is claimed. Explicit provider-bound claim/nonce validation and real-provider acceptance remain required before production authentication closure.
+
+Android nonce/logout working source now passes151 JVM tests, zero lint errors/warnings and APK/native-test compilation. Independent26-file diff review is completed/sealed as c358cde3-b51d-4451-b07d-8d1afe6c4485 with no findings; this is source-scoped and does not establish native/browser/provider execution. Core combined nonce/test corrections remain in progress; initial diagnostic failures stay failed.

+# QQQ Mobile Scanners TODO
+
+Current checkpoint (November 4; supersedes historical notes below):
+
+- [x] Scanner PR 12 merged `286e2e0`; full run 3645 succeeded. Central snapshot `0.1.0-20261103.233448-3645` verified anonymously, including all 37 published Java source files.
+- [x] Android PRs 10 and 8 merged into main `0ae2101`; full main lifecycle 3634 succeeded. Shared CI's independent registry readback matched all ten primary library files at `0.1.1-20261103.232145-3634`.
+- [x] Qualify released Printing `1.0.0` with public QQQ RC.21: 198 tests pass, Checkstyle passes, all 94 scanner Java files match reviewed source, and no private QQQ backend artifacts remain in that cohort.
+- [x] Adopt that cohort on local port 57832 while retaining the database/settings. Confirm API health, TC22 Echo setup/Copies 1/Connected and Print Agent Connected and ready after restart.
+- [x] Adopt and review Printing `1.0.0` in both Echo POMs and matching READMEs. Both Maven validate/Checkstyle checks pass; 94 Java inputs match the 198-test qualification.
+- [ ] Document owner: extract reviewed code from host candidate `b6fb238` with provenance, set public dependency pins and standard standalone release wiring, then publish coherent document/files/scripting Maven artifacts including Generation copies. The local standalone directories are not Git repositories and have no workflows; the website image pipeline does not publish these artifacts. Claude access is restored; the dependency owner's actual Claude standalone packaging is active as of November 4, not finished.
+- [x] Outstanding manual acceptance group: user reported on November 4, "i have ran the manual tests - it all works". Recorded as operator acceptance in [TC22 acceptance](../TC22-ACCEPTANCE.md); no duplicate manual checks requested. Separate per-case artifacts were not supplied.
+- [ ] Resolve or explicitly scope the unsupported GS1/ECI/binary scanner profiles before claiming universal barcode reproduction.
+- [ ] Production Android signing/distribution last, as requested. Development publication and demo availability are not production 1.0 acceptance.
+
+Historical checkpoint (November 3):
+
+- [x] Server `45f9cbd` is signed and pushed (Gitea PR 7). Android `f72b90d` is signed and pushed to the existing AGit PR 10 head and Gitea CI 3480 succeeded on it (pull requests #8 and #10 still open; not merged, not released). Updated normal APK installed without clearing data; fresh disposable TC22 Echo run passed 109/109 semantic requests (simulated inputs/printing).
+- [x] Final RC.21 gate PASS: 377 unique tests (Generation 179, Printing bridge 16, scanner 53, demo 8, mobile Record Files 18, Echo 68, Echo demo 35), zero failures/errors/skips, Checkstyle PASS, plus 15 real admin-browser E2E on public RC.21. The earlier MySQL timeouts did not recur (focused 31, full 179). Evidence: `C:/Users/james/.cache/qqq-rc21-copies-gate-076d059d8d0641d9a85874ec64008def/verified-summary.json`.
+- [x] Verified dependency update: five RC.21 POM pins and the record-files POM test fix (BOM-managed Jupiter engine/params, all 6.0.2).
+- [ ] This is public core RC.21 plus qualified owner inputs, not a fully public or released cohort: the 16 Printing-bridge tests still resolve three private `pu507` QQQ libraries through the owner Printing POM, and the other owner qbits remain qualified private inputs. Public reproducible owner inputs, primary source CI, merge and release remain open. No normal-runtime core upgrade was done.
+- [x] Generation copies: signed `aac68907e67906aeef4e0cd687d28bc98b738f8c` on `feature/echo-generation-copies` (base PR 343 head `8f473fa`) in `Website-Backend/third-party-src/qbit-document-generation`; 13 paths, 21/21 manifest match; real PostgreSQL 17 migration passes. [ ] Owner integration and public artifact publication not yet acknowledged.
+- [x] Fresh real Authentik desktop acceptance passes; native harness integrated (8 guards pass). [ ] Native TC22 run needs the temporary CA and PIN (pending); no trust bypass.
+- [ ] Manual physical checks: trigger, AIM, fidelity, label count, photo, GPS, projection. [ ] Signing and distribution last, by user decision.
+
+Previous checkpoint (November 2; historical, superseded by the current checkpoint above):
+
+- [x] Optional Copies per scan defaults to 1, accepts 1–100 and remains server-pinned for every scan/retry. Live on the original local server57832; normal TC22 setup shows 1.
+- [x] Verify 377 unique server/owner tests across the module runs, plus real TC22 ten-stage/116-request semantic acceptance with simulated scans/printing.
+- [x] Adopt mobile-scanners1.5 and actual mobile-record-files1.0/Echo photo composition locally, preserving the original database and printer settings. Photo authorization tests pass.
+- [ ] Confirm physical label count/fidelity and real camera/GPS/projection/provider behavior; operator currently remote. Temporary Authentik CA installation is unconfirmed.
+- [ ] Obtain canonical owner adoption/publication of the verified Generation copies handoff: ten hash-checked files for the Kof22 release repository's `third-party-src/qbit-document-generation` (base verified identical), then a published Generation coherent with Echo's `generation.version`; complete coherent artifacts/CI. Signing/distribution stays last.
+
+Current demo path (November2; supersedes historical runtime/pairing notes below):
+
+- [x] Implement and verify additive mobile1.5 raw-byte/AIM transport, exact retry binding, optional context and preserving H2 migration:135 scanner/demo/Echo tests pass. Android counterpart is implemented; native capture and installed-runtime adoption remain open.
+- [ ] Qualify actual TC22 raw-byte delivery, AIM extraction and decoder settings; finish renderer scanner-mode/extended-symbology integration. Transport support alone does not establish same-symbol reproduction.
+- [x] Fix and adopt the Generation/renderer byte-limit mismatch in both demo launchers; three failures with old wiring, 74 passing library/demo tests with the fix. One clearly synthetic native HTTP event now reaches the actual Windows printer spooler through Echo, with process cancellation verified after failure and acceptance. Paper output, TC22 trigger capture and rescan remain separate open checks.
+- [x] Render the actual published 4x1 document through the real renderer and independently decode its Code128 and leading-zero QR pixels; both preserve exact value/symbology and fit the configured stock. See [evidence and test images](../../examples/echo/demo/docs/ECHO-RENDERER-ACCEPTANCE.md). Physical printing remains unverified.
+- [x] Correct the five inert test-token secret-scan findings using generated fixtures and exact historical fingerprints; local historical/staged scans and all 27 demo tests pass. Current primary CI remains an open gate.
+- [x] Run all real scanner/Echo, files, document and printing qbits in the single local server57832; original accounts work; full demo27 and live forwarded-host checks pass.
+- [x] Connect the existing installed print client to57832 and approve its available ZPL printer through the native QQQ process; no job/default changes.
+- [x] Verify the Android same-origin header (Android `fb3cc5d`, 174 JVM tests) and TC22 sign-in, heartbeat, printer/media/document selection and Cancel/Leave against the strict local host, preserving data.
+- [x] Resolve the earlier 4x6 media report versus loaded 4x1 stock with the Printing owner (101600 x 25400 microns, 300 dpi) and publish the real Echo 4x1 barcode document with its matching immutable revision 1.
+- [ ] Complete one physical Code128 (QQQ-TEST-123456) scan, print and rescan on the TC22, then leading-zero QR. One synthetic HTTP test job reached `SPOOLED`; physical paper output and handheld acceptance are not yet proven.
+- [ ] Finish the existing production-readiness matrix and publication gates; local demo acceptance alone does not complete 1.0. Public coherent artifacts, primary Gitea CI and final signing remain open, with signing last by user decision.

+# Echo — scan a barcode and print a copy
+
+Echo is an optional QQQ example application, using the shared Android scanner host. Choose a currently authorized printer and its supported paper/label profile once, then scan repeatedly. Each scan preserves its string value and actual symbology and uses the existing Document Generation → retained original → native Printing path. One event is admitted per run at a time. A successful acknowledgment means **queued**, not confirmed physical paper.
+
+The source implements ordinary QQQ metadata and processes; no Echo-specific Android screen, business endpoint, barcode encoder or print queue is added. There is deliberately no fabricated printer, hardcoded stock, administrative-permission shortcut or in-process renderer fallback.
+
+## At a glance
+
+- **Flow.** Choose a printer, its paper/label size and a published Document once; then every scan renders the same value and symbology and prints one job, until you leave. **Copies per scan** is optional (default 1, range 1–100) and fixed for the run.
+- **Where it runs.** The maintained local server composes Echo with Collaboration/Record Files, Document Generation and Printing on public QQQ `4.1.0-RC.21` and released Printing `1.0.0` (UI API 1.10, `mobile-scanners` 1.5, `printing` 2.3). Start it with the [runnable demo](demo/README.md); [local demo](../../docs/LOCAL-DEMO.md) explains how it differs from the basic Scan Capture demo.
+- **Verified.** In the current 198-test cohort Echo has 68 tests and the composed demo 35, with Checkstyle clean ([session state](../../docs/SESSION-STATE.md)). The automated composed acceptance (an approved scanner, two scans, two retained originals, two accepted jobs, an idempotent retry, leaving) uses a controlled synthetic renderer and a simulated Printing queue.
+- **Rendering evidence.** The real renderer's Code128 and leading-zero QR outputs pass independent pixel decoding and stock/fit checks ([evidence and test images](demo/docs/ECHO-RENDERER-ACCEPTANCE.md)). A separate synthetic HTTP event reached a real printer spooler ([delivery receipt](demo/docs/echo-delivery-acceptance.json)).
+- **Physical acceptance.** The TC22 trigger, paper output and rescan checks were reported by the operator as passing on November 4, as a group report without per-case artifacts. A queue acknowledgment still means *queued*, not confirmed paper.
+- **Not claimed.** Production readiness, signed distribution, public Maven coordinates for the document owner's qbits, or universal barcode fidelity ([limits](#fidelity-and-limits)).
+
+## Host composition
+
+1. Install/configure the existing Mobile Scanners, Document Generation and retained-source Printing integration under their owner-qualified dependency tuple. Use the same backend/data source for Echo metadata and its state schema. Apply [`echo-h2.sql`](src/main/resources/db/echo-h2.sql) through host migrations; registration performs no DDL.
+2. Configure Document Generation to allow `echoScan` as a source table. Publish appropriate immutable barcode templates through its ordinary definition service and isolated worker. Stock measurements are micrometres with explicit DPI. Do not generate or publish a new template on every scan.
+3. `EchoPrintingDestinations` implements the destination seam from Printing's public operator authorization (`PrintingOperatorAuthorization`) and reported media profiles. `authorize` checks the current actor, printer row, device and ZPL format and pins the exact reported media profile id and revision. `plan` reauthorizes, then reads the published template revision with enforced permissions and requires its stock to equal that media. The setup step's printer field uses Printing's own table possible values (enabled and available printers); `EchoMediaChoices` is a semantic possible-value provider that returns only the sizes of the printer already selected. App-selected document dimensions do not imply changing Windows printer stock.
+4. `EchoDocumentGenerator` calls Generation's public `generate` and read-only `lookupAcceptedPrint` with the exact template, revision, stock and selected media profile, under the stable key `echo:<scanId>`. `QUEUED` is returned only for a durable, available retained receipt with a job id and the same media profile. Absent or unavailable lookup evidence refuses. It never uses the side-effecting `reconcile` call or plain byte submission.
+5. `EchoHost.install(instance, deployment)` composes the above from the owners' public classes: Record Files retained output and print source, `PrintingDispatch.forOwnerMediaEnforcement(source)` (the owner's explicit adoption factory), Generation with its durable audit, then Echo. Registration order matters: Printing, then Echo's `echoScan` table, then Generation, which validates its source tables. The isolated renderer, `PrintingService` and template map are deployment inputs; absent ones are refused. Grant the operator `echo.use`, ordinary mobile scanning and the owner-approved generation and print-submit permissions. **Do not grant `printing_admin` to make Echo work.** `EchoTemplatePublisher.publish` is the one-time operator action that publishes the ZPL barcode template for one reported media profile.
+
+Supply the renderer's configured byte limit as `Deployment.maximumOutputBytes`. Both demo launchers propagate `ECHO_RENDERER_MAXIMUM_BYTES` to Generation and the renderer. Leaving Generation at its 20 MiB owner default with a 1 MiB renderer rejects every render request before the worker starts. The composed acceptance uses a bounded renderer and a nondefault 256 KiB cap. Existing six-argument `Deployment` callers retain the owner default and must only use it with a renderer that accepts that allowance.
+
+The process begins with server-owned run state, shows printer/media setup, then loops only between the semantic SCANNER frontend and the print backend. Its native Cancel step closes the run, including cancellation during setup. Already processing or accepted work may still print; leaving prevents new admission and retains receipts. Protected framework process identity, rather than an echoed run ID alone, binds the selected printer to that process.
+
+## Copies per scan
+
+Setup asks **Copies per scan**: an optional ordinary integer form field, default 1, registered with core `ValueRangeBehavior` limits of 1 and 100 (inclusive, error) so the native client's `validation.minValue/maxValue` match the server. Omitted, null or blank means 1; fractions, 0, 101 and non-numbers are rejected at setup. The server validates it, pins it on the run (`echo_run.copies`, a non-null additive column that defaults existing runs to 1) and uses that pinned count for every scan until Leave. A repeated setup can confirm but not change it, and a differing scan-stage `copies` value is refused before any event row exists; the value never decides what is printed. The scanner instructions state the count when it is above one. Bounds are Printing's own: a whole number from 1 to 100, expressed by that owner as the `copies` option of **one** print job, so Echo never queues one job per copy or renders per copy, and retries and lookup reuse the same pinned count.
+
+`EchoDocumentGenerator` builds `DocumentGenerationService.Request(..., mediaProfile, copies)` with the run's pinned count, so Generation binds it to the `echo:<scanId>` key and its printing bridge submits one job with `options.copies`; the accepted-print lookup compares the committed count with the pinned one before Echo adopts a job. This needs the Generation copies cohort (`GenerationPorts.PrintRequest`/`Request` with the appended `copies`, the request-table `copies` migration `20261102-print-copies-h2.sql`, and a Printing owner that honors `options.copies`); an owner without `supportsCopies()` refuses a count above 1 before any row, render or submit. Physical copy counts are not verified.
+
+## Fidelity and limits
+
+| Input | Behavior |
+| --- | --- |
+| CODE128, QRCODE, CODE39, Data Matrix, PDF417, Aztec (printable ASCII) | Admitted on the plain document. |
+| EAN13, EAN8, UPCA, UPCE0 | Admitted only with the scanner's AIM identifier, an exact-length value with a valid check digit (UPC-E number system 0 only) and a document published with `publishScannerFidelity`; otherwise refused before any print. |
+| GS1-128 (`]C1`) | Bounded profile below; requires matching raw-byte evidence and a separate GS1 document with printed HRI. |
+| Other GS1, ECI and structured-append modes (for example `]Q3`, `]A4`) | Refused; no qualified profile. |
+| Control, binary or non-ASCII payloads | Refused. |
+| UNKNOWN symbology or manual entry | Refused. No symbology is inferred from the value or substituted with QR/Code128. |
+| Raw bytes (`rawDataBase64`, mobile-scanners 1.5) | Must decode to exactly the ASCII bytes of the displayed value, else refused. Required for GS1-128; absent evidence remains admitted for legacy plain profiles and proves nothing. |
+
+Independent decoding (ZXing on the rendered raster) is recorded only for Code128 `QQQ-TEST-123456` and QR `001234567890` on 4 x 1 in stock at 300 dpi. Hardware AIM output and physical copy counts are covered by the operator's accepted group report (not reopened), but have no separate instrumented evidence; no exact-AIM or all-symbology claim is made.
+
+The first explicit mapping covers CODE128, QRCODE, CODE39, Data Matrix, PDF417 and Aztec scanner identifiers and their documented legacy label aliases. Leading zeros are never parsed as numbers. EAN13/EAN8/UPCA/UPCE0 are admitted only with the scanner's AIM identifier (`]E0`, EAN-8 `]E4`), a full-length value of the exact length with a valid GS1 check digit (UPC-E number system 0 only), and a document published with `EchoTemplatePublisher.publishScannerFidelity`. That separate, clearly named **scanner-fidelity** document passes the recorded scanner label and AIM identifier (`echoScan.symbology`, new nullable `echoScan.aimIdentifier`) to the renderer's scanner mode, which verifies them again and converts the value. It requires an AIM identifier on every scan, so the original plain document stays the choice for older scanners and servers; an EAN/UPC scan on a plain document, or a scan without AIM on a scanner-fidelity document, is refused before any print and the operator leaves Echo to choose the other document. The AIM column is an additive, nullable migration in `echo-h2.sql` (other databases need the equivalent); a retry is bound to the stored AIM. UNKNOWN, manual input, unsupported variants and control/binary payloads outside the GS1-128 profile below are refused until their exact metadata/encoder profile is qualified. When the canonical scan context carries the optional mobile-scanners 1.5 evidence, Echo checks it before admission: outside the GS1-128 profile, an `aimIdentifier` other than the renderer's plain-mode identifier for that type (for example `]Q3`, `]A4`) is refused as a GS1/ECI/structured mode, and `rawDataBase64` must decode to exactly the ASCII bytes of the display value. Absent evidence (legacy 1.4 servers, older clients, or a Zebra read where the host did not confirm its AIM output profile by configuration read-back) is admitted as before and proves nothing, and physical AIM output on the handheld is not yet qualified; no fidelity is inferred from the display string. No symbology is inferred from value or substituted with QR/Code128.
+
+Each canonical mobile scan has one durable `echoScan` source with the same ID and a stable `echo:<scanId>` generation request key across every run. A duplicate accepted event in the same run returns its existing job; moving that event into another run is rejected. A deliberate new trigger event with the same value is a new print intent. A changed value/type/source/timestamp cannot reuse the event. An uncertain/crashed call never automatically renders or prints again: recovery requires read-only exact owner acceptance evidence; absent/unavailable evidence remains visibly unconfirmed and the user may leave. Independent decoding and physical scanner/printer acceptance remain mandatory for any claimed barcode profile.
+
+## Build and acceptance
+
+From the repository root, use Java 21 and the included wrapper:
+
+```text
+./mvnw -f examples/echo/pom.xml verify
+```
+
+On Windows, run `mvnw.cmd -f examples/echo/pom.xml verify` from the repository root. From `examples/echo`, use `../../mvnw -f pom.xml verify` (Windows: `..\..\mvnw.cmd -f pom.xml verify`). Both forms use the checked-in wrapper; Checkstyle and resource paths resolve from the module directory.
+
+This optional module is outside the root lifecycle. The POM's defaults are `qqq.version` 4.1.0-RC.21 (public), `printing.version` 1.0.0 (released Printing, qualified with public RC.21), and `mobile.version` and `generation.version` 0.1.0-SNAPSHOT. The other owner qbits (Generation and bridges, Collaboration, Record Files, Scripting) are still qualified owner inputs, not a public or released dependency cohort, so their snapshot defaults alone may not resolve or match what was verified. Copies per scan also needs the Generation copies change described above. Use a dedicated Maven repository and one coherent owner cohort; never install cross-chat snapshots over the shared cache. When the owner publishes public versions, adopt them in a reviewed dependency change; until then do not guess coordinates. The source requires the narrow protected-process-identity API and the current `MobileScannerActions.capture(input, appName)` API. The primary forge is Gitea; GitHub is a shadow/archive.
+
+Tests: core and HTTP-fixture tests (real QQQ process state, H2 persistence and the mobile QBit's approval and binding, with synthetic destination, layout and queue fixtures) and adapter tests (controlled owner facades for exact pins, receipts, lookup, media filtering, the published scene geometry and the absent-deployment refusals). They qualify orchestration, event identity, permission boundaries and adapter mapping, not render output or physical printing. The adapter tests do not run the renderer worker.
+
+## Runnable demo
+
+[`demo/`](demo/README.md) is a separate optional module that composes the real owners into a startable server (tested, Checkstyle clean). Its production `EchoDemo` keeps the owner's cold bridge, which defaults to the `runsc` Docker runtime and fails closed on Windows Docker Desktop (`runc`). `TrustedLocalEchoDemo` is the explicit developer launcher over the renderer owner's public trusted-local factory (the demo copies no transport) and is not a production sandbox qualification. Operator prerequisites, from its README: a Printing tenant and administration token, a Windows printing agent that reports printer media, an approved scanner enrolled through the mobile flow, published Echo-compatible ZPL templates for the reported media (chosen by the operator during process setup), and Record Files' generated-file release switch. The demo README's first section says which launcher to use; the basic Scan Capture demo is a different, smaller server ([local demo](../../docs/LOCAL-DEMO.md)).
+
+## Release limits
+
+Echo is an example, not a released product. Source and development publication are done on Gitea (scanner `develop` snapshot from run 3645; Android `main` `0ae2101`, run 3634). Still open: public Generation/bridges/Record Files/Scripting artifacts from their owner, signed-build HTTPS device qualification and distribution (the signed Android APK and channel already exist locally), and any barcode profile beyond the [limits above](#fidelity-and-limits). Earlier GitHub references are historical.
+
+## License packaging
+
+Echo uses Apache License 2.0. Packaging includes the existing repository `LICENSE` and `NOTICE` unchanged under `META-INF/qqq-echo/`, alongside Echo's SQL resources. This namespace preserves dependency notices. No duplicate license source files or modified license text are maintained in the example.
+
+## Isolated native UI fixture
+
+`com.kingsrook.examples.echo.fixture.EchoHttpFixture` is a test-scope HTTP host using the existing demo TABLE authentication and registered QQQ semantic routes. It brands itself **Echo UI E2E — simulated printing**. The simulated printer/media and acceptance recorder exercise navigation and receipts only; they never render or print.
+
+Launch its test classpath with one unused loopback port argument and private environment variables `ECHO_FIXTURE_TYPE=echo-ui-e2e`, `ECHO_FIXTURE_SCANNER_PASSWORD`, and `ECHO_FIXTURE_ADMIN_PASSWORD`. Use generated secrets of at least 24 characters. Accounts are `scanner` and `admin`. The process initializes a fresh random in-memory H2 database, refuses known production/test-peer ports, and emits `ECHO_UI_E2E_READY port=<port> simulatedPrinting=true`. Closing it stops only its own server. Keep its credentials in private run descriptors, never this repository.
+
+The printer/media choices are `fixture-printer` / `fixture-4x6`, labeled “Simulated printer” / “Simulated 4 x 6 in — 300 dpi”. Standard native queries of `echoScan` and test-only `echoFixtureRun` use the scanner session and approved device credentials, retaining actor locks. The HTTP smoke covers login, real enrollment/admin approval, metadata, setup, two symbologies, same-event retry, queued receipts, row inspection and cancellation. Android device acceptance remains a separate test; none of these fixture results qualify physical output.
+
+Retained Echo source reads use a separate read-only permission: the current authenticated actor must still have `echo.use`, and native actor row locks restrict results to that actor. Desktop source reads after leaving Echo do not reconstruct a scanner session or grant capture authority. Echo app/process/widget/capture operations still require the currently approved device. Direct source-table writes are denied. Accepted print delivery/retry also requires the printing owner's reviewed original-actor source-reauthorization policy; this table read rule alone does not qualify delayed byte release.
+
+### GS1-128 duplication profile
+
+Choose a separate document created with `EchoTemplatePublisher.publishGs1`; existing plain documents cannot print GS1 scans. This profile requires AIM `]C1`, a supported Code128/GS1 scanner label, and raw bytes matching the original payload (optionally including its AIM prefix). It preserves the original scan and derives `rendererValue` and `humanReadable` in additive nullable columns. Apply the H2 additions in `echo-h2.sql` before use; other database owners must supply equivalent migrations.
+
+Supported AIs: fixed-length `00`, `01`, `02`, `11`, `12`, `13`, `15`, `16`, `17`, `20`; variable-length `10`, `21`, `30`, `37`. ASCII group separators terminate variable fields; boundaries are never guessed. The bounded profile admits at most 48 payload characters and refuses unknown AIs and unsupported controls. Example: `01095011015300031120101421TEST000123` prints `(01)09501101530003(11)201014(21)TEST000123` below a GS1-128 barcode. The renderer checks the canonical data independently.
+
+Two synthetic 4-by-1-inch, 300-dpi outputs passed independent decoding with exact GS1 data, matching HRI and non-overlapping geometry. Native acceptance is in progress; physical print/rescan and suitability for the operator's actual media remain unverified.

+# Echo runnable demo checkpoint
+
+> Historical checkpoint (2026-11-02). Its test counts and "Remaining" list are superseded: see the [demo README](README.md) and [session state](../../../docs/SESSION-STATE.md) for current status.
+
+Date: 2026-11-02. Scope: `examples/echo/demo/**`. Source checkpoint, not a release.
+
+## Verified status
+
+- Demo module `verify`: **24 tests pass, Checkstyle 0** (acceptance 3, settings 5, startup 1, object files 6, trusted-local renderer settings 9), against the real new Echo read checker and the renderer owner's TL1 factory. Parent `examples/echo` `verify`: 45 tests pass.
+- The renderer owner's own tests for the TL1 trusted-local exchange pass (52 owner tests). The demo uses the owner's public factory and copies no transport.
+- **Complete composed acceptance (`EchoDemoAcceptanceTest`) passes** over a fresh private file database: an authenticated, approved scanner runs the real `echoPrint` process through real Generation, Record Files retention and Printing job acceptance. Two scans (Code 128 `001234567890`, QR `QR-VALUE-0099`) give exactly two retained originals and two accepted Printing jobs on the one selected printer and media; a retry of the same event returns the same job and renders nothing again; leaving closes the run (`CLOSED`).
+- **Controlled inputs, not physical output:** the renderer returns fixed synthetic ZPL built from the exact context Generation passes it, and the "printer" is a Printing device and queue enrolled through the owner's public `PrintingService` API. No Docker, agent, printer or device is touched.
+- A private fresh-JVM run of the demo was observed live on a local ephemeral loopback port (take the URL from the startup log line `ECHO_DEMO_READY port=<port>`, `http://127.0.0.1:<port>`): scanner and admin native login and metadata returned 200. No printer or template exists on it, and no physical print has been attempted.
+
+## What the demo does
+
+`EchoDemo` extends `MobileScannersDemo` (database, `scanner`/`admin` accounts, native server) and composes Collaboration, Record Files, Printing, Document Generation and `EchoHost.install` from their public classes on one private H2 file (`WRITE_DELAY=0`). Composition runs under a scoped system context that is restored afterwards, then `QInstanceEnricher` enriches the instance, because the server only validates and the enricher registers Collaboration's record-feature permissions. `LocalFilesystemAttachmentStorage` implements the attachment owner's storage SPI over `PrivateObjectFiles` (hashed keys, temp-file-then-link, no overwrite) and adds no policy. `TrustedLocalEchoDemo` is the explicit developer launcher; the production `EchoDemo` default fails closed. See `README.md` for build, run and environment.
+
+Authentication is the existing demo password/session module plus exact grants. `scanner`: `echo.use`, `printing_operator`, `document-generation.view|generate|print`, `record-files.view|manage`, `echoScan.attach` and the `printing_tenant` row key (replaced, never appended, on each validation); then `CollaborationSecurity.applyToSession`. `admin` additionally: `printing_admin`, `document-generation.configure|publish`. No Record Files release/configure/audit for anyone.
+

+# Echo runnable local demo
+
+Optional module (`qqq-echo-demo`) that turns the Echo example into a server you can start. The library module `examples/echo` does not depend on it. It reuses `MobileScannersDemo` (database, `scanner`/`admin` accounts, native server) and adds Collaboration, Record Files, Printing, Document Generation and Echo from their public production classes. Nothing is simulated: the renderer is the owner's cold Docker bridge, output is retained by Record Files, and printing is Printing's own service. The server binds `127.0.0.1` only.
+
+## Which launcher?
+
+| Goal | Use |
+| --- | --- |
+| Try login, device approval and basic barcode capture only | The basic Scan Capture demo, `scripts/Start-Demo.ps1` ([local demo](../../../docs/LOCAL-DEMO.md)). Not this module. |
+| Run the full scan, render and print flow on a developer machine | `TrustedLocalEchoDemo` (below). |
+| Production-style cold renderer sandbox | `EchoDemo`; it fails closed unless the owner's `runsc` runtime is available. |
+| Keep using the maintained local server's existing database | Either launcher with `ECHO_EXISTING_DATABASE` set ([adoption notes](docs/LOCAL-SERVER-ADOPTION.md)). Only this mode accepts host port `57832`. |
+
+There is **no default port**: pass one as the argument or set `ECHO_DEMO_PORT`. A local run prints its URL in the startup log (`ECHO_DEMO_READY port=<port>`, then `http://127.0.0.1:<port>`).
+
+## Status
+
+The demo and Echo library tests pass with Checkstyle clean (current cohort: Echo 68, composed demo 35 tests; see [session state](../../../docs/SESSION-STATE.md)). The QQQ default is 4.1.0-RC.21 and Printing defaults to released 1.0.0; the other owner qbits remain qualified owner inputs until their public release. The composed acceptance test passes with a controlled synthetic renderer and a simulated Printing queue, so it is **not physical output**. TC22 physical acceptance is separately operator-reported as passing (November 4, group report). Not production-ready and not a public SDK release. The dated [`CLAUDE-HANDOFF.md`](CLAUDE-HANDOFF.md) is a historical checkpoint.
+
+## Trusted local development launcher
+
+`TrustedLocalEchoDemo` is a separate, explicit main for a developer machine. It starts the same server, accounts, permissions and loopback binding as `EchoDemo`, but builds the owner's `IsolatedRendererBridge(exchange.limits(), RetainedAssetReader, exchange)` over the renderer owner's supported public `TrustedLocalDockerExchange`, built from `TrustedLocalDockerExchange.configuration(...)`. This is **not** a production sandbox qualification: it has no repository digest, uses the owner's literal unqualified local qualification id, and is not gVisor. The production `EchoDemo` default is unchanged and fails closed, and neither launcher falls back to the other. The owner's exchange and its tests are the transport boundary; this demo adds no transport of its own.
+
+The exchange requires the renderer artifact `qbit-document-generation-renderer` at a version that contains it. The demo POM's `renderer.version` property defaults to `${generation.version}`; override it for the private cohort, for example `-Drenderer.version=0.1.0-echo.gen64c9pu507.tl1`. Only the direct renderer dependency uses that property.
+
+The launcher passes the owner factory: the Docker executable and exact image id from the environment below, a state directory `<ECHO_DEMO_ROOT>\renderer-state` (created if absent, absolute, not a symbolic link), the fixed owner id `echo-local`, the deadline, maximum bytes and pages, and a maximum concurrency of 1. Use a **fresh private `ECHO_DEMO_ROOT` for each runtime**: the journal there must belong to this process alone. At startup it calls the exchange's `reapExpired()` once, which reclaims only this owner's expired leases left by a killed process and logs a warning with the count of any it could not reclaim.
+
+Extra environment (in addition to the shared settings below, except the `ECHO_RENDERER_*` cold-bridge variables, which this launcher does not use):
+
+| Variable | Meaning |
+| --- | --- |
+| `ECHO_LOCAL_RENDERER` | Must be exactly `TRUSTED_LOCAL_DEVELOPMENT`; anything else refuses startup. |
+| `ECHO_LOCAL_RENDERER_DOCKER` | Absolute path of an existing Docker executable. |
+| `ECHO_LOCAL_RENDERER_IMAGE_ID` | The exact local image id, `sha256:` plus 64 lowercase hex characters. Tags and repository digests are refused. |
+| `ECHO_LOCAL_RENDERER_DEADLINE_SECONDS` | Optional, 1-30, default 10. |
+
+`ECHO_RENDERER_MAXIMUM_BYTES` (default 1048576) and `ECHO_RENDERER_MAXIMUM_PAGES` (default 1) also apply. The owner's exchange refuses the render unless the daemon reports runc, linux and exactly the configured image id. Launch exactly as in "Build and start" but with this main class:
+
+```powershell
+java -cp "examples\echo\demo\target\classes;$(Get-Content examples\echo\demo\target\classpath.txt)" com.kingsrook.examples.echo.demo.TrustedLocalEchoDemo 48123
+```
+
+The log line reports `renderer=trusted-local-development`. The unit tests (`TrustedLocalRendererSettingsTest`) never start Docker.
+
+## Build and start
+
+From the repository root, with the checked-in wrapper (`mvnw.cmd` on Windows) and the tuple installed in your Maven repository:
+
+```powershell
+.\mvnw.cmd -B -f examples\echo\demo\pom.xml verify
+.\mvnw.cmd -B -f examples\echo\demo\pom.xml dependency:build-classpath "-Dmdep.outputFile=examples\echo\demo\target\classpath.txt"
+```
+
+Set the configuration below in the environment (never on the command line), then:
+
+```powershell
+java -cp "examples\echo\demo\target\classes;$(Get-Content examples\echo\demo\target\classpath.txt)" com.kingsrook.examples.echo.demo.EchoDemo 48123
+```
+
+The optional argument is the port; otherwise `ECHO_DEMO_PORT`. There is no default port, and the sign-in passwords are never given on the command line (see below; to copy an existing demo account's password without displaying it, use `scripts/Copy-DemoPassword.ps1`). Ports 1024-65535 are accepted except the protected local runtimes listed in `EchoDemoSettings`. `mvnw.cmd -f examples\echo\demo\pom.xml exec:java` is equivalent when the environment is set.
+
+## Configuration (environment only)
+
+Required:
+
+| Variable | Meaning |
+| --- | --- |
+| `ECHO_DEMO_ROOT` | Existing private absolute directory (not a symlink). The H2 file database lives in `<root>\db\echo`. |
+| `ECHO_DEMO_PORT` | Loopback port, unless passed as the argument. |
+| `ECHO_PRINTING_TENANT` | Printing tenant label. Operator sessions are locked to it. |
+| `ECHO_PRINTING_ADMIN_TOKEN` | 32-1024 character bearer token for Printing's administration routes. |
+| `ECHO_RENDERER_DOCKER` | Absolute path of the Docker executable. |
+| `ECHO_RENDERER_IMAGE` | Digest-pinned image `repo@sha256:...` (the qualified catalog-9 cold image). |
+| `ECHO_RENDERER_IMAGE_ID` | `sha256:...` image id. |
+| `ECHO_RENDERER_QUALIFICATION_ID` | Owner qualification evidence id. |
+| `ECHO_RENDERER_REQUIRED_QUALIFICATION_ID` | Must equal the evidence id above. |
+| `ECHO_RENDERER_OWNER_ID` | Deployment owner id for renderer admission. |
+| `ECHO_RENDERER_STATE_DIR` | Existing private absolute directory for renderer state. |
+| `MOBILE_DEMO_SCANNER_PASSWORD`, `MOBILE_DEMO_ADMIN_PASSWORD` | First startup only, 12+ characters, as in the mobile demo. Existing accounts are never changed. |
+
+Optional: `ECHO_RENDERER_DEADLINE_SECONDS` (10, max 30), `ECHO_RENDERER_MAXIMUM_BYTES` (1048576), `ECHO_RENDERER_MAXIMUM_PAGES` (1), `MOBILE_BRAND_*` (as the mobile demo), `ECHO_RELEASE_GENERATED_FILES=true`.
+
+Retained files are stored by `LocalFilesystemAttachmentStorage` (the attachment owner's own storage SPI) under `<root>\objects`. Keys are hashed into file names, writes are temp-file-then-link and never replace an object. It adds no policy: Record Files and the attachment owner still decide quarantine, authorization and lifecycle. Single host, demo only.
+
+`ECHO_RELEASE_GENERATED_FILES=true` sets Record Files' generated-file quarantine policy to off. Without it generated output is quarantined, Echo sees it as unavailable, and every print is refused. Turn it on only if you trust every producer allowed to retain generated output in this deployment.
+
+The legacy `ECHO_TEMPLATE_ID`, `ECHO_TEMPLATE_MEDIA_ID` and `ECHO_TEMPLATE_MEDIA_REVISION` pin no longer selects a document and is ignored. The operator chooses the document at the start of every run from the published templates described below.
+
+## Accounts and permissions
+
+`scanner` receives exactly: `echo.use`, `printing_operator`, `document-generation.view|generate|print`, `record-files.view|manage` (manage is the owner's intake permission) and the `printing_tenant` row key. `admin` receives the same plus `printing_admin` (Printing's native pairing/approval/setup processes) and `document-generation.configure|publish` to prepare templates. The scanner never gets these, and nobody gets Record Files release/configure/audit. Scans still need an enrolled and approved device, so use the existing mobile enrollment flow.
+
+## Operator order
+
+1. Start the host. Enroll the Windows printing agent against `/printing/v1` and let it report printer media.
+2. As `admin`, publish one or more ZPL templates for the reported media in Document Generation (scene per `EchoTemplatePublisher`; give each its own name with `EchoTemplatePublisher.publish(definitions, media, name)`). Each published, compatible template becomes a separate Document choice.
+3. As the scanner, open Echo: choose the printer, then the paper or label size, then the Document (offered only from published `echoScan` templates whose stock equals that size and whose scene draws the scanned value and type dynamically). The three choices are fixed for the run; leave Echo and reopen it to change them.
+
+## Echo scan photos (mobile Record Files)
+
+The host also installs the existing `qbit-mobile-scanners-record-files` integration, so an approved scanner can attach photos to one of its own retained Echo scans. Nothing new is served: Record Files' registered, versioned `record-files` upload API (`/qqq/v1/qbit/record-files/...`) and the independently versioned `mobile-record-files` widget vocabulary are advertised in `/qqq/v1/version`, behind the same native auth and device guards.
+
+- **Process:** `echoScanPhotos` ("Echo scan photos"), listed in the Echo app. It requires `echo.use`, `echoScan.attach` and a verified approved device. The first step lists the actor's own scans (the table's record security lock decides; label is the barcode and type, never the record id). The server then re-reads the chosen scan through the collaboration owner's visibility and `attach` checks and builds the `RECORD_FILES_CAPTURE` widget from the record that check returned, on the fixed `echoScan` table. The client never supplies a table or record reference, and rendering the widget directly names no parent. Record Files authorizes the parent again on every upload operation.
+- **Policy:** JPEG/PNG only, 20 MiB per file, up to four files, 256 KiB chunks, private staging under the demo's `objects` directory (separate staging namespace). Retained originals follow the existing Record Files quarantine setting.
+- **Needs a real scan first:** the list is empty until the scanner has Echo scans. Nothing is seeded outside this module's tests.
+- **Existing databases:** the Record Files upload tables are added by the same tolerated-reapply schema step; plan the migration for a database from another version.
+- **Not claimed:** no real photo upload, native capture or device run has been verified here. That needs the Android host against this server.
+
+## Existing databases
+
+Startup applies each owner schema with "already exists" tolerated, plus the four shipped Generation H2 migrations (output filenames, warm batch completion, print media profile and print copies, the last adding the nullable `copies` column where null means one copy). It does not migrate a database created by a different version. Plan migration separately for anything beyond a fresh demo root.

+# Echo barcode rendering acceptance
+
+On November 2, 2026, the real renderer produced the two labels below from the local server's published Echo template revision 1. ZXing 3.5.3 independently decoded the emitted raster pixels, preserving both the symbology and the exact value. The live server's published revision and stock were checked again after rendering and matched the tested descriptor.
+
+| Input | Decoded format | Decoded value | Raster size |
+| --- | --- | --- | --- |
+| Code128 | `CODE_128` | `QQQ-TEST-123456` | 600 × 180 dots |
+| QR | `QR_CODE` | `001234567890` | 208 × 205 dots, including byte padding |
+
+The stock is 101600 × 25400 microns (4 × 1 inches) at 300 dpi: a 1200 × 300 dot label. Both graphics start at (48, 48), fit inside the published printable margins and fit rectangle, and contain the requested barcode. The checks validated the ZPL envelope, raster byte counts, output hashes, placement, dimensions, decoded format and string-exact value. The QR value was never converted to a number.
+
+The renderer was the owner's `IsolatedRendererBridge` over its explicit trusted-local Docker exchange, using image `sha256:c124af0d890f1bb206422e97a1f997d863ea6a8b2225cecf32be726a252c9ee4`. This is development verification, **not production sandbox qualification**. The renderer received fixed test record contexts; no hardware scan was fabricated and no printer job was sent.
+
+The [machine-readable receipt](echo-renderer-acceptance.json) records the original ZPL hashes and all checks. The previews below were reconstructed from those ZPL raster bytes, not generated separately from the expected values.
+
+## Code128 test input
+
+Open [the full-size Code128 image](barcodes/code128-preview.png) and scan it once in Echo for the physical test.

+
+Open [the full-size QR image](barcodes/qr-preview.png) when testing leading-zero preservation.
+
+![QR label containing 001234567890](barcodes/qr-preview.png)
+
+## Remaining acceptance
+
+The later [delivery check](echo-delivery-acceptance.json) uses a different, explicitly synthetic HTTP event (`ECHO-HTTP-TEST-001`). It traverses the real Echo process, renderer, retained output and installed Printing agent. Exactly one matching job reached `SPOOLED`, with a Windows spooler job assigned; native Cancel then closed Echo. It also exposed and verified the fix for the Generation/renderer byte-limit mismatch. This additional evidence does not turn either fixture into a physical handheld scan or confirm paper output.
+
+These two decoded artifacts prove these rendering cases. They do not prove physical trigger capture, printer delivery, printed-label readability, other inputs or symbologies, or production release readiness. Complete the TC22 scan → server print → printed-label rescan, deliberate repeated scans and Leave/error recovery. Keep the remaining device/provider, barcode-fidelity, dependency-publication and primary CI gates open.

+# Running all qbits in the local test server
+
+> The combined server is the maintained local server (host port 57832 in this mode only; public QQQ RC.21, Printing 1.0.0; API 1.10, mobile 1.5, printing 2.3). The "now responds ... Mobile Scanners 1.4" sentence at the end is a November 2 note; see [session state](../../../../docs/SESSION-STATE.md) for the current versions.
+
+One server, one database: the existing `MobileScannersDemo` data file is opened in place by the combined `EchoDemo` (Mobile Scanners/Echo, Collaboration/Record Files, Document Generation, Printing). No second server, network bridge or reset.
+
+## Environment contract (public values only; no secrets are read from or written to this file)
+Use the existing `TrustedLocalEchoDemo` (or `EchoDemo`) launcher plus the normal Echo variables, and add:
+- `ECHO_EXISTING_DATABASE` - absolute path of the existing H2 file, ending `.mv.db` (for the basic demo's database: `demo/data/mobile.mv.db` under your checkout, as an absolute path). Setting it is the explicit existing-local-server mode.
+- `ECHO_DEMO_PORT` - `57832` is accepted only in this mode. Every other protected port (including peer Printing 18081) is still refused, and fresh/private demos still refuse 57832.
+- `ECHO_DEMO_ROOT` - existing absolute directory for Record Files objects and renderer state (`objects`, `renderer-state`); the database is NOT taken from it in this mode.
+- Unchanged: `ECHO_PRINTING_TENANT`, `ECHO_PRINTING_ADMIN_TOKEN` (32+ chars), `ECHO_RELEASE_GENERATED_FILES`, renderer variables (`ECHO_LOCAL_RENDERER*` or `ECHO_RENDERER_*`), `MOBILE_BRAND_*`.
+
+## Behavior
+- The database is opened with `IFEXISTS=TRUE;DATABASE_TO_UPPER=FALSE;DB_CLOSE_DELAY=-1;LOCK_TIMEOUT=5000;WRITE_DELAY=0`. A missing file, a name not ending `.mv.db`, a relative path, a directory, a symbolic link or a reparse point is refused at startup and nothing is created.
+- Startup adds only missing schema (`CREATE TABLE IF NOT EXISTS`, owner migrations). Accounts, password hashes, devices, device credentials, approvals and scans are never seeded, changed or reset; the `MOBILE_DEMO_*_PASSWORD` values are ignored in this mode.
+- Authentication remains `EchoDemoAuthentication` over the existing demo accounts, native provider and device authorization. Restarts are idempotent.
+- Requires the same H2 runtime (2.2.224) that wrote the file.
+
+## Test
+`EchoDemoAdoptionTest` uses temporary directories and fresh ports: baseline `MobileScannersDemo` with accounts, an approved device and a scan; the same file opened through `EchoDemo`; hashes, credentials, approval and scans unchanged; old logins work and new passwords do not; the one `QInstance` exposes Mobile, Echo, Record Files, Collaboration, Generation and Printing; idempotent restart; missing/wrong-suffix/relative/directory refusal; port guards. Both adoption tests passed in the full 26-test demo verification, with zero Checkstyle violations.
+
+## Local development
+Stop the existing development server and start the combined launcher with the variables above. This is a normal greenfield development restart. Do not run two servers against the same file concurrently (H2 file lock).
+
+The TC22's existing `adb reverse tcp:8080 tcp:57832` connection sends the device-side `Host: 127.0.0.1:8080`. The loopback hostname check accepts a valid forwarded port while retaining exact same-origin and cross-site request checks. The scanner account still requires its approved device proof before Echo appears in its app catalog.
+
+The combined server now responds on 57832 with API 1.10, Mobile Scanners 1.4 and Printing 2.3. Both original accounts authenticate, and authenticated metadata includes Printing, Document Generation and Record Files. The remaining demo acceptance is the installed print client's connection, a compatible published document, and physical scan/print/rescan on the TC22.

+# Echo owner adapters and host composition handoff (Claude adapters role)
+
+Updated: 2026-11-01. Scope: `examples/echo` library module. Primary forge: Gitea. This handoff makes no claim that Echo has printed, that anything is published to a public Maven repository, or that it is production-ready.
+
+## Verified state (reported by root; I ran nothing)
+
+- `mvnw verify` for this module: **38 tests pass**, **Checkstyle 0** (2026-11-02), against a complete private owner cohort: Generation and bridges `0.1.0-echo.gen64c9pu507`, Printing protected main `64c9ebf`, core `4.1.0-pu.507b0d21e09d7eebb76782d14660483c45c77b11`, 15 artifacts. The POM defaults (`qqq.version` 4.1.0-RC.20, `generation.version` 0.1.0-SNAPSHOT, `printing.version` 0.4.0-SNAPSHOT) are not that cohort.
+- Scanner source `707e1ab` (Gitea PR 7): scanner 50, demo 7 and Record Files 18 tests pass. Android `c55d300` is retained inside migration merge `a2f0080` (identical tree).
+- Runnable demo (`demo/`): **22 tests pass, Checkstyle 0**, with the new Echo read checker (it accepts Collaboration's and Record Files' plain capability probe for sessions with `echo.use`) and the renderer owner's TL1 trusted-local factory (52 owner tests pass; the demo copies no transport). Its clean composed acceptance passes: authenticated approved scanner, real `echoPrint`, real Generation, Record Files retention and Printing job acceptance; two scans give two retained originals and two accepted jobs on one printer, a retry gives the same job, and leaving closes the run. It uses a controlled synthetic renderer and a simulated Printing queue. A local run was observed live on an ephemeral loopback port (scanner and admin native login and metadata 200) with no printer or template. The production `EchoDemo` default still fails closed on Windows Docker Desktop (`runc`, not `runsc`).
+- TC22 native five-stage flow and 86 semantic API calls pass **against simulated printing only**.
+- No real-renderer template publication, independent decode or physical print has happened. Remaining: the actual native Printing client connection and stock handoff, physical scan/print/rescan, full AIM/EAN/UPC/GS1/raw fidelity (the six types are printable ASCII only and the rest fail explicitly as unsupported), then public immutable SDK, Gitea CI/distribution and signing, last.
+
+## What exists (all under `examples/echo`)
+
+- `EchoPrintingDestinations`: `authorize` requires the scanner identity's actor to equal Printing's current principal (`PrintingOperatorAuthorization`), checks the printer row, device and ZPL format, and pins the exact reported media profile id and revision (`PrintingMediaProfile`). `plan` reauthorizes, picks the template through `EchoTemplates`, reads the published template and revision with enforced native permissions, and requires its stock to equal the media. `media(printerId)` lists only that printer's authorized sizes.
+- `EchoMediaChoices`: semantic custom possible-value provider. It reads the posted `printerId` dependency from `SearchPossibleValueSourceInput.getOtherValues()` and returns that printer's sizes only; no printer means no choices; a bare `getPossibleValue` refuses. The public id is the owner's profile id and the private revision pin stays in `authorize`.
+- `EchoQBitProducer`: setup's printer field uses Printing's own table possible values (`printing_printer`) with `enabled` and `available` filters.
+- `EchoTemplates`: exact key of renderer symbology, media id and media revision; `forMedia` maps the admitted symbologies to one template.
+- `EchoTemplatePublisher.publish(definitions, media)`: one-time operator action creating type, stock equal to the reported media, ZPL-only binding for `echoScan`, and the template. Scene `qqq-zpl-scene/1`: `symbologyPath=/record/rendererSymbology`, `valuePath=/record/barcode`, allowlist, `quiet=10`, `fit` box inside the stock, no scanner-attestation paths.
+- `EchoDocumentGenerator`: Generation's public `generate` and read-only `lookupAcceptedPrint` with exact `Expected` tuple and `MediaProfile` under key `echo:<scanId>`. `QUEUED` only for a durable, available retained receipt with a job id and the same media profile. Lookup must match source, destination and media; absence refuses; `reconcile` is never used.
+- `EchoHost.install(instance, Deployment)`: `RecordFilesPrintSource`, `RecordFilesOutputIntake`, **`PrintingDispatch.forOwnerMediaEnforcement(source)`** (the owner's explicit adoption factory in the printing bridge; the plain constructor still denies selected media), `DocumentGenerationQBitConfig` with `echoScan` as source table and `GenerationAudit`, `PrintingQBitProducer`, then `EchoOwnerAdapters.config` and `EchoQBitProducer`, then `DocumentGenerationQBitProducer`. That order is required: Generation validates its source tables, and an earlier order failed the demo with "Unknown generation process source table". `Deployment` carries `printingBackend`, `generationBackend`, `echoBackend`, `echoState`, `printing`, `renderer` and `templates`; null `printing`, `renderer` or `templates` are refused.
+- `EchoService`: admits scanner identifiers `CODE128`, `QRCODE`, `CODE39`, `DATAMATRIX`, `PDF417` and `AZTEC` (and their `LABEL-TYPE-` aliases). `EchoTemplates.SYMBOLOGIES` is exactly `code128, qr, code39, datamatrix, pdf417, aztec`.
+
+## Fidelity: what is and is not claimed
+
+- Six types are admitted; **EAN13, EAN8, UPCA and UPCE0 are refused before `EchoStore.claim` or generation** (regression in `EchoTest.unsupportedAndControlPayloadsFailWithoutPrinting`: generator never called, zero `echoScan` rows). The worker converts their full-length scans only in scanner mode, which needs the AIM identifier Echo does not record.
+- Not supported and not claimed: EAN/UPC, GS1, raw or binary payloads, control characters, UNKNOWN or manual input. Completing the original barcode-fidelity scope (AIM evidence, then EAN/UPC) is open work after the first Code 128 and QR pilot; the six admitted types are not claimed complete.
+- The published scene was checked by file review against the worker source (`ZplRenderer`, `BarcodeFit`, the owner's `BarcodeFitTest` fixture shape) and the worker's integer dot arithmetic for 4 x 6 in at 300 dpi (x=y=48 dots, fit 93600 x 144400 µm). `EchoOwnerAdaptersTest` asserts that shape and arithmetic. **No test runs the real worker on the Echo template.**
+
+## Owner and deployment boundaries still open
+
+1. **Renderer transport.** An owner-provided explicit cold trusted-local Java transport for Windows Docker Desktop; `catalog-9` image qualification is also listed open in `renderer/BARCODE-FIT.md`. `EchoHost` refuses to start without an `IsolatedRenderer`.
+2. **Template publication through the real worker.** `freeze` calls `renderer.validate` on the exact scene, so a publish that returns a template id is the worker's acceptance. Then `DocumentGenerationService.preview(new Request(templateId, new Source("echoScan", rowId), ZPL, key, null), draftFingerprint)` renders a retained original with no print destination, for geometry inspection and independent decode of a Code 128 value and a leading-zero QR value such as `001234567890`.
+3. **Printing service and agent.** A `PrintingService` for a tenant, a Windows agent exposing `printer-media-v1`, and a ZPL-capable printer at 203, 300 or 600 dpi are deployment items.
+4. **Permissions** (no `printing_admin` on the operator): `echo.use`, an approved scanner, Printing's operator catalog permission and `PrintingOperatorProcesses.SUBMIT`, Generation view/generate/print, read on Generation template and revision tables (for `plan`), and Record Files release and read grants for the original actor.
+5. **Original-actor source reauthorization** for delayed byte release belongs to Printing's retained source authority (`RecordFilesPrintSource`), and acceptance is still queue acceptance, not paper.
+6. **Format.** The publisher is ZPL-only; the printer must report ZPL. A PDF variant is not written.
+7. **Distribution.** The cohort is private and unpublished. Public Maven publication, hosted CI, signing and release are not done.
+
+## Test inventory
+
+24 core and HTTP-fixture tests (`EchoTest` 23, `EchoHttpFixtureTest` 1) and 14 adapter tests (`EchoOwnerAdaptersTest`): exact profile mapping, unknown or malformed media refusal, template keys, exact request pins, no-queue results, undurable or unavailable or missing receipt refusal, read-only lookup, mismatched-media lookup, printer-filtered media choices, bounded printer dependency, absent deployment parts refused, and the published scene geometry. Total 38, verified by the coordinator.

+# Echo required Document choice (server and native UI verified)
+
+## Process contract (ordinary QQQ metadata; Android renders it generically)
+`echoPrint` frontend step `setup`, form fields in order:
+1. `printerId` - Printing's own printer possible values (unchanged).
+2. `mediaId` - possible value source `echoMedia`, `dependsOn=[printerId]` (unchanged).
+3. `templateId` - label **Document**, required, **INTEGER** (Generation template id), possible value source `echoDocument` (`idType=INTEGER`, custom `EchoDocumentChoices implements QCustomPossibleValueProvider<Integer>`, registered by `EchoQBitProducer` if absent), `dependsOn=[printerId, mediaId]`.
+
+HTTP (published `searchProcessPossibleValues`): `POST /qqq/v1/processes/echoPrint/possibleValues/templateId`, JSON `{"values":{"printerId":"...","mediaId":"..."},"processValues":{},"useCase":"form"}`; optional `searchTerm`, `ids`. Returns `{"options":[{"id":<JSON integer>,"label":"<template name>"}]}`. Either dependency missing returns no options; an unauthorized printer or unknown size is refused. `ids` arrive as strings and are coerced strictly (plain digits or integers only, else 400).
+Setup submit value: `templateId` as a JSON integer. `EchoSteps.documentId` accepts an integral number, or plain digits from a text form; fractions, exponents, blanks, overflow, booleans and values below 1 are refused. Persisted: `echo_run.templateId` and `templateRevisionId` are INT; the library HTTP fixture's `echoFixtureRun` table now exposes both as INTEGER fields (Android E2E reads `templateId`).
+`EchoService.start/select` and `EchoDestinations.DocumentChoice` now use `Integer` ids.
+
+## Server rules
+- `EchoDestinations.authorizeDocument(identity, destination, templateId)` and `documents(printerId, mediaId)` (new). `EchoPrintingDestinations` reads Generation `document_generation_template`/`_revision` with `PermissionEnforcement.ENFORCE` (query for choices, get for authorization). A template is eligible only if: it is for `echoScan`, has a published non-PREVIEW revision for `echoScan`, the revision's stock width/height/dpi equal the chosen media, and (ZPL) its scene is `qqq-zpl-scene/1` with a barcode element using `symbologyPath=/record/rendererSymbology`, `valuePath=/record/barcode` and an allowlist covering all of `EchoTemplates.SYMBOLOGIES`. Static, wrong-symbology or other-size templates are never listed or accepted. Nothing else is substituted.
+- Setup (`EchoService.select`, step `start`) validates a numeric `templateId`, authorizes printer+media then the document, and stores `templateId` and `templateRevisionId` on `echo_run` once. Replays with a different document are refused (same rule as printer/media).
+- Every scan: `claim` returns the run's pinned document; `EchoDestinations.plan(identity, destination, document, scan)` reauthorizes the destination, re-reads the template and requires the current published revision to equal the pinned one, else fails visibly ("changed or was withdrawn", Leave stays available). Print/Scan steps never read `templateId` input. Single in-flight, idempotent same-event retry, pin compare-and-set and durable-receipt ordering from 101efc8 are unchanged. A run with no document (pre-migration row) refuses to print.
+- `EchoTemplates` (host catalogue) and the `ECHO_TEMPLATE_*` demo pin no longer select anything (`EchoHost.Deployment` lost its `templates` argument, `EchoOwnerAdapters.config` lost `templates`; the helper class remains for the symbology list). `EchoTemplatePublisher.publish(definitions, media, name)` publishes additional named documents.
+
+## Migration
+`echo-h2.sql`: `ALTER TABLE echo_run ADD COLUMN IF NOT EXISTS templateId INT` and `templateRevisionId INT`. Idempotent; existing rows are kept with NULL. Other databases need the equivalent additive columns (not provided).
+
+## Tests (root verified)
+- `EchoTest`: setupRequiresAnAuthorizedCompatibleDocument, documentChoicesComeFromTheNativePossibleValueSearch (real SearchPossibleValueSourceAction), chosenDocumentIsUsedForEveryScanAndCannotBeRetargeted (repeated scans, forged process value, setup replay), changedOrWithdrawnDocumentFailsVisiblyWithoutSubstitution, documentMigrationPreservesExistingRuns; existing tests updated to pass a document. Library suite:45 tests pass (29 process/persistence,15 adapters,1 native HTTP fixture). Full composed demo:24 tests pass. Both enforce Checkstyle0.
+- `EchoOwnerAdaptersTest`: onlyDynamicSameSymbologyScenesAreEligibleDocuments (15 tests).
+- `EchoHttpFixtureTest`: real HTTP possible-value search plus selected document.
+- `EchoDemoAcceptanceTest` (real HTTP, real Printing/Generation/Record Files): two compatible published documents plus one other-size document; the PVS offers exactly the two; missing/unknown/malformed/wrong-size documents refused; document B chosen, used by every render across scans, replayed setup and a forged `templateId` on a later scan do not retarget.
+
+Added in the typed-contract pass: `EchoDemoAcceptanceTest.republishedDocumentFailsVisiblyWithoutReplacementAndLeaveStillWorks` (real owner `DocumentDefinitionService` republish of the chosen template after setup: the next scan and its retry fail visibly, one render and one Printing job in total, Leave closes the run, and a fresh run offers and prints the republished document); integer-id and strict-coercion assertions in `EchoTest`; all possible-value requests in the fixture and demo tests use the JSON `{values, processValues, useCase}` POST, not multipart. Each demo test runs under the existing before/after connection-provider reset.
+
+## Process-state trap (diagnosed from current core source; fix is in Echo, not core)
+Both composed failures had one cause. In core, `RunBackendStepAction.runStepCode` catches any exception thrown by step code and replaces the result with `new RunBackendStepOutput()` (an empty `ProcessState`); `RunProcessAction` (line ~810) then stores that state under the process key before rethrowing. The new state has no `ProcessStateAccess`, so the next USER request fails `primeProcessState` -> `ProcessStateAccess.requireAccess(null, ...)` -> "Permission denied for process state" (the 403 on Leave). So a thrown business refusal (replayed/invalid setup, republished document at scan time) trapped the operator, including their own mistakes. No auth check was weakened.
+Fix (example only): `EchoSteps.Start` and `Print` now record a `QException` with `output.setException(...)` instead of throwing. The output then shares the input's `ProcessState` (`seedFromRequest`), so the stored state, ownership record and values survive, and core still raises the exception to the client as the ordinary process error. Operators can correct a setup choice in the same process, retry the same scan, or Leave.
+Core proposal (not applied, peer-owned): in `runStepCode`'s catch, keep the input's process state (call `runBackendStepOutput.seedFromRequest(runBackendStepInput)` before `setException`) so a thrown step exception cannot drop ownership for any process. Evidence: `RunBackendStepAction.java` lines 325-330 and `RunProcessAction.java` lines 810 and 646-652.
+Test truth: `EchoDemoAcceptanceTest` setup-replay and republish cases are unchanged and now rely on this; new `EchoTest.businessRefusalsNeverTrapTheProcessAndLeaveStillWorks` proves correction in the same process, a refused scan, and Leave. Not run.
+
+## Not covered / gaps
+- No test for an unauthorized-to-read template: Generation has no template-specific grant, only table permissions, so it needs a new security grant that was not invented here.
+- A true withdrawal is not tested: the owner's `DocumentDefinitionService` has no withdraw/unpublish call, only republish. Republish (changed revision) is the real owner path covered.
+- Android: no change needed; the new field is ordinary dependent metadata. Not exercised on Android here.
