 # Changelog
 
+## Unreleased (0.4.0-SNAPSHOT)
+
+Printing extension **2.3.0** (additive; wire payload v1 and the agent subprotocol are
+unchanged). 2.1.0 added the record, table-list and text print processes; 2.2.0 added
+`printingRenderToPdf`, the header and footer values on every document and content
+sections; 2.3.0 adds the least-privilege operator catalog/submission/request lookup,
+reported Windows queue-default media (`printer-media-v1`) and the opt-in
+retained-source facade. Clients should offer a feature when its process is in the
+metadata, not by comparing versions. An agent that does not advertise
+`printer-media-v1` stays a three-capability peer and cannot claim a job carrying a
+media selection, whatever extension version it discovers.
+
+- Realtime shutdown now waits, with a bound, for channel workers that are already
+  running before the host's durable state is released. Previously the executor was
+  only told to stop, so a late drain could query a stopped file database and
+  recreate it empty (found as a temporary-directory cleanup error in a full test
+  run).
+
+Observed locally on the merged candidate: full `-Pui-demo verify` 189 reported,
+188 executed, one intentional opt-in workload skip, zero failures/errors, zero
+Checkstyle violations; five consecutive focused realtime runs passed. Hosted CI on
+the final signed head, publication and consumer qualification have not run; no
+physical output is claimed.
+
+- The app's header and footer on every page of every document (record sheets,
+  table lists, text and content pages): app name, title or breadcrumb, server,
+  user and printed-at at the top; the client's footer (e.g. `qqq ui 1.0.1 ·
+  server`), a list's filter and sort, and "Page n of m" at the bottom. Clients
+  send `headerApp`, `headerTitle`, `headerServer`, `headerUser`, `headerPrintedAt`,
+  `footerLeft` and `footerNote`; missing ones default to the instance branding,
+  the session user, the current instant and "QQQ printing".
+- Content documents: `printingPrintText` and `printingRenderToPdf` (`TEXT`) take
+  `sections` (JSON `[{title, lines}]`), a screen's panels without navigation or
+  borders, rendered as headings with their lines wrapped to the page width.
+- Save as PDF: `printingRenderToPdf` renders the document a print would carry -
+  a record sheet (`kind` `RECORD`, `tableName`, `recordId`), a table list (`LIST`,
+  the `printingPrintTableList` values) or a text page (`TEXT`) - and returns it to
+  the caller as the standard process download (`downloadFileName`,
+  `serverFilePath`) instead of queueing a job. No printer is needed; reads enforce
+  the caller's permissions, and a list over the limit says so in
+  `printingMessage`. Clients offer it as "Save as PDF…" in their printer pickers.
+- Print anything: `PrintingRecordProcesses.registerAll(instance)` adds **Print** to
+  every table that can be read one record at a time (call it after the host's
+  tables are in the instance). Hidden tables, tables without a primary key or
+  `TABLE_GET`, and tables carrying `PrintingTableSettings().withPrintable(false)`
+  are skipped.
+- The record sheet now follows the table's metadata: field sections in tier order
+  with their labels, remaining fields under "Other fields", and a summary of each
+  child list (association): its label, row count and first ten rows.
+- New `printingPrintTableList`: a table list (grid) of any readable table with the
+  caller's columns (in order) and widths, filter and sort, either the whole result
+  (`scope` `ALL`, the default: read a thousand rows at a time up to `maxRows`,
+  10,000 by default and at most; a larger result prints its first rows and says
+  so in the header and in `printingMessage`) or the current page (`PAGE`, the
+  filter's skip/limit). Letter or A4; orientation `AUTO` (landscape when the
+  columns need it), portrait or landscape. The header repeats on every page; the
+  page header carries the table, the rows printed of the total, the filter text
+  and the sort, and the footer the table, time, user and "Page n of m".
+  `printingRowCount` reports the matching rows before printing.
+- New `printingPrintText`: any text (a capture of a terminal screen) as a
+  monospace PDF, wrapped and broken across pages.
+- All documents share one page writer with "Page n of m" footers and a running
+  title on later pages. Table and record reads enforce the user's permissions.
+
+## 0.3.1-SNAPSHOT
+
+- Add record printing: `PrintingRecordProcesses.register(instance, table)` adds a
+  **Print** process (`printingPrintRecords_{table}`) to a host table's records and
+  selections. It asks for an approved, exposed PDF printer and a copy count, shows
+  the standard review, then renders each selected record as a Letter record sheet
+  (`PrintingRecordDocuments`: heading, visible non-binary fields with display
+  values, wrapped and continued across pages) and queues one PDF job per record.
+  The queued job IDs are returned in the process value `printingJobIds`.
+- Fix selection actions whose first step is a form (**Print a test page**,
+  **Print a test label** on selected printers, and **Print**): over the UI API the
+  record selection reaches only the init call, so the review answered "No records
+  were selected". The prepare step now keeps the selection as `queryFilterJson`.
+
+## 0.3.0-rc.1 — 2026-10-31
+
+Upgrade the server before the matching Windows connector. Native printing API
+2.0 requires synchronized authenticated WSS; old native clients cannot claim
+without it, and there is no polling fallback. Wire payloads remain v1.
+
+- Add client-initiated realtime WebSocket delivery under native printing API 2.0,
+  with current QQQ session and record permissions revalidated during connection use.
+- Deliver desired state, device commands, inventory, lifecycle events and receipts
+  over the socket; native claims require acknowledged current settings and state.
+- Stream retained documents independently from controls and expose document,
+  concurrency, timing, admission and retention batch limits in native admin forms.
+- Preserve durable job/command identities across reconnects. Installed Windows
+  realtime and physical-output acceptance remain separate from source/test gates.

+For terminal and web clients the QBit also offers ready-made print processes: `PrintingRecordProcesses.registerAll(instance)` (after all host tables are added) puts **Print** on every readable table, rendering a record sheet from the table's sections and child lists; `printingPrintTableList` prints a grid of any table (columns, filter, sort, page or all rows, paper and orientation); `printingPrintText` prints text such as a screen capture. Opt a table out with `PrintingTableSettings().withPrintable(false)`. Each returns the queued job id in `printingJobIds`. `printingRenderToPdf` (extension 2.2.0) renders the same documents to a PDF download for the caller instead ("Save as PDF"), and every document carries the app header and footer the client sends (`headerApp`, `headerTitle`, `headerServer`, `headerUser`, `headerPrintedAt`, `footerLeft`, `footerNote`).
+
 The returned ID identifies durable queue acceptance. Check job status asynchronously. The [protocol v1 specification](https://github.com/QRun-IO/qqq-print-protocol/blob/f977bd01b62ceb7539190fd2861809537fcf504c/README.md) defines HTTP endpoints, JSON fields, integrity checks and lifecycle semantics.
 
 For durable QQQ jobs register `PrintEnqueueEffectTarget` as an `IDEMPOTENT_EXTERNAL` target in `DurableJobsMetaData`, then emit the submit-request payload. The target replaces the payload idempotency key with the durable effect key. Its SENT result means accepted into the queue, not physical output. This implementation uses its own JDBC transaction; do not register it as LOCAL_TX. Authorize the destination in the emitting process before writing the effect. QQQ's durable dispatcher runs with a `QSystemUserSession` and does not propagate the user's tenant keys. For that trusted outbox path only, the target resolves the service configured on the dispatcher's current QQQ instance; that service fixes the tenant and rejects devices belonging to another tenant. The payload cannot choose a service or tenant. A cached target resolves the current instance on every call. Inline user calls retain the `printing_tenant` scope check, and native management processes (including enrollment) still require both administrator permission and matching tenant scope. Do not expose direct effect emission through an arbitrary user-supplied target/payload endpoint.

+Run the optional real-provider checks with Docker Compose and PowerShell 7.4+.
+The pinned fixture images use Linux/amd64; other hosts need Docker's corresponding
+Linux-container support or emulation:
+
+```powershell
+pwsh ./dev/Invoke-Dev.ps1 -Action Test -Authentik
+```
+
+The command creates a fresh, owned development project, runs the normal QQQ and
+MinIO smoke test plus the Authentik reference checks, then removes that project's
+containers and volumes. It does not operate the installed Windows connector,
+existing Docker stacks or physical printers. It needs no cloud account.
+
+For an environment that remains available for development, use `-Action Start`
+with an explicit `-StateDirectory` outside the checkout. Use that same directory
+with `-Action Test -Authentik`, then `-Action Stop` when finished. Stop destroys
+only that owned project's synthetic databases and objects; retained private
+reports are separate. See the [development command](Invoke-Dev.ps1) for port
+overrides. Authentik defaults to `http://127.0.0.1:19010`;
+its database port is not published. The QQQ host remains on standard TABLE
+authentication.
+
+## What the automated check establishes
+
+- Real Authentik 2026.8.5 starts with a separate PostgreSQL 16 Alpine database.
+- A synthetic confidential OAuth provider/application and development user are
+  configured through Authentik's API. The callback list is explicit and grants
+  are limited to authorization code and refresh. Access/refresh validity is
+  two/ten minutes for a future bounded renewal test.
+- Actual provider discovery has the expected issuer, same-origin endpoints and
+  S256 capability. A valid state/S256 request with the registered callback
+  continues to the provider login flow without following it. Changing only that
+  callback to an unregistered redirect is rejected before any user login.
+- The current QQQ RC.20 host advertises UI API 1.8 without `nativeSessionLogin`.
+  That expected absence is recorded as a native-client prerequisite failure,
+  not silently replaced by bearer authentication or an unpublished core.
+
+`auth-result.json` distinguishes those checks from browser login, renewal and
+the Windows callback, which are **not run**. Provider setup/discovery is not an
+OIDC user-session integration test. No password login dialog is automated.
+
+## Credentials and ownership
+
+The common entrypoint creates a protected state directory outside the checkout.
+`Invoke-Authentik.ps1 -Action Initialize` appends only its `AUTHENTIK_*` settings
+to `compose.env`, preserving the QQQ/MinIO settings. It records synthetic
+credentials in private `auth-secrets.json`; neither file belongs in Git, a bug
+report or terminal output. Bootstrap uses a Django password hash. The temporary
+bootstrap API token remains confined to this disposable project and disappears
+with its database at cleanup. Do not reuse these accounts outside the fixture.
+
+The Docker administrator can inspect container configuration. The scripts do not
+print credentials or provider error bodies, follow redirects with an API token,
+or request raw container logs. HTTP reads have a 15-second cancellation deadline
+and a 512 KiB response limit. Startup has a bounded readiness loop. Initializer
+replays retain credentials; conflicting or partial state is refused.

+
+There is no Redis requirement for this Authentik version, Docker socket mount,
+outpost management, shared volume or automatic restart policy. Container and
+volume labels identify the exact generated Compose project. The common cleanup
+checks those labels before removing resources; it never performs a global prune.
+
+## Separate native-session qualification
+
+The Windows native path requires the centrally defined API 1.9 typed
+`AUTHORIZATION_CODE_PKCE_SESSION` grant and trusted HTTPS on both QQQ and provider
+origins. RC.20 does not supply that grant, and this HTTP development profile does
+not weaken the client's HTTPS rules. The synthetic reference callback is only a
+provider configuration value; no callback receiver or QQQ OAuth adapter is
+claimed here. The TABLE host and installed pairing are unchanged.
+
+The separate [experimental native profile](native-auth/README.md) builds an exact
+public, unreleased QQQ candidate inside Docker and uses private container-only
+HTTPS trust. On 2026-11-01 it passed actual provider login, native permission
+denials, logout replay rejection, renewal after expiry and provider revocation
+with the production Core client. Its synthetic HTTP driver and HTTPS callback
+receiver do not qualify the installed Windows browser UI or private URI callback.
+
+Production adoption still requires a compatible published central artifact
+tuple. Provider refresh tokens stay on the server. The short lifetime test does
+not prove months or years of unattended use. Do not route the private Windows
+callback to a live companion whose connection must remain intact.
+
+The setup follows the official [2026.8 Compose definition](https://goauthentik.io/version/2026.8/lifecycle/container/compose.yml),
+[bootstrap contract](https://docs.goauthentik.io/install-config/automated-install/)
+and [OAuth provider contract](https://docs.goauthentik.io/add-secure-apps/providers/oauth2/).
+The repository supplies the repeatable local setup; provider/browser acceptance
+is reported separately from TABLE authentication and printing workload tests.
+
+## Initializer regression tests
+
+With Pester 5 available, run `dev/tests/Authentik.Tests.ps1`. They use temporary
+files only: no Docker, HTTP, installed service or registry access is required.
+Disable Pester's unrelated registry fixture on Windows:
+
+```powershell
+$configuration = New-PesterConfiguration
+$configuration.Run.Path = './dev/tests/Authentik.Tests.ps1'
+$configuration.Run.Exit = $true
+$configuration.TestRegistry.Enabled = $false
+Invoke-Pester -Configuration $configuration

+Prepares or checks the optional, owned Authentik development fixture.

+Initialize only writes private state. Test configures a fresh synthetic provider
+and checks its real HTTP discovery and rejection boundary; it never automates a
+user login or changes QQQ authentication. The common development entrypoint owns
+all Docker lifecycle operations. Provider response bodies and secrets are never
+printed, including on errors.

+# Local Docker development
+
+Use this repository to start a separate QQQ application or run synthetic printing
+checks. Nothing imports an installed connector's pairing, accesses physical
+printers, or needs a cloud account. Docker Compose and PowerShell 7.4+ are required;
+Git identifies the checkout. Docker must support Linux/amd64 containers. The first
+build downloads pinned public images, Maven dependencies and the verified Windows
+Core source archive. Java and .NET run inside Docker; neither host SDK is required.
+
+## Start, test and stop
+
+From the repository root, the default command runs 65 S3 checks and 40 network
+jobs, saves protected reports, and removes its containers and synthetic volumes:
+
+```powershell
+pwsh ./dev/Invoke-Dev.ps1 -Action Test
+```
+
+For a persistent development application, start it and keep the state-directory
+path printed by the command:
+
+```powershell
+pwsh ./dev/Invoke-Dev.ps1 -Action Start
+pwsh ./dev/Invoke-Dev.ps1 -Action Test -StateDirectory '<printed state directory>'
+pwsh ./dev/Invoke-Dev.ps1 -Action Stop -StateDirectory '<printed state directory>'
+```
+
+Open `http://127.0.0.1:19081`. The standard QQQ TABLE login username is `developer`.
+Read `QQQ_ADMIN_PASSWORD` from the generated, protected `compose.env` locally;
+never paste that file into an issue or commit it. There is no default password.
+The host provides native printing screens, settings, a dedicated MinIO document
+bucket and scheduled retention. No printer is enrolled automatically in this host.
+The test workload uses a separate disposable database and object store.
+
+Add `-Authentik` when creating an environment or running a fresh test to include
+real Authentik/PostgreSQL. See [the provider checks and remaining native grant
+prerequisite](AUTHENTIK.md). Provider discovery does not establish successful OIDC
+user login or refresh; the current QQQ RC.20 API lacks that native-client grant.
+
+```powershell
+pwsh ./dev/Invoke-Dev.ps1 -Action Test -Authentik
+pwsh ./dev/Invoke-Dev.ps1 -Action Test -Workload 10000
+```
+
+The optional 10,000-job run keeps admission limits enabled, uses eight synthetic
+clients across two tenants, and reports client process memory, latency and
+receipt counts. It is a bounded burst, not a day-long soak or physical throughput
+claim. The default 40-job run measures idle event delivery one job at a time.
+
+## Isolation and cleanup
+
+Each environment has a unique `qbit-printing-dev-<random>` Compose project and
+matching ownership labels. All published ports bind only to `127.0.0.1`: QQQ19081,
+MinIO19095 and optional Authentik19010. Override them with `-QqqPort`, `-MinioPort`
+and `-AuthentikPort` when creating a new environment. Occupied ports fail startup;
+the command never stops another service to free them. PostgreSQL is not published.
+
+State defaults to the current user's application-data directory, outside the
+checkout, with private filesystem permissions. A custom `-StateDirectory` must
+also be outside the checkout. It holds generated fixture credentials, frozen
+Compose files, ownership records and sanitized result files. Docker administrators
+can inspect container configuration; use these credentials only for this fixture.
+
+`Stop` validates container, network and volume ownership before removing that
+project's resources. **It deletes that environment's synthetic databases and
+objects.** It leaves reports and ordinary image/build caches in place and never
+runs a global prune. A fresh one-command `Test` performs this cleanup in `finally`,
+including on failure. Tests against an existing environment remove only their
+three test containers; finish with `Stop` to remove its disposable test volume and
+the persistent development environment. Do not edit its frozen ownership files.
+
+Images are pinned by digest in Compose/Dockerfiles. Containers have bounded CPU
+and memory, no automatic restart, and no Docker socket. The default profile has
+no host credential or source mounts. QQQ/test containers additionally cap process
+counts. Builds copy
+only explicit source inputs. The QQQ and MinIO containers share their own network
+namespace so the existing loopback S3 backend can be used without relaxing
+production endpoint validation.
+
+## What the results mean
+
+- The S3 fixture exercises the actual QQQ `StorageAction`/S3 backend and AWS SDK,
+  including a multipart-size document, hashes, tenant namespaces, immutable
+  binding checks, retention and unrelated-object preservation.
+- The workload uses the real current Java server and pinned Windows Core client:
+  native TABLE authentication, outbound WebSocket notifications, event-driven
+  claims, document downloads and durable server receipts. A fake file printer
+  verifies bytes and rejects duplicate submission. It cannot produce paper.
+- The fixture's client receipt journal is intentionally simple; these results do
+  not replace production SQLite crash-recovery tests. MinIO fixture credentials
+  are unrestricted within their owned store and do not qualify production IAM.
+- Connections here are HTTP/WebSocket on an isolated local project. TLS, provider
+  browser consent/renewal, real deployment policies and hardware behavior are
+  separate qualifications. No silent bearer-authentication fallback is added.
+
+Results include `result.json`, `server-result.json`, `s3-results.json` and
+`execution.json` under a run directory. The persistent host also writes
+`qqq-result.json`; optional provider checks write `auth-result.json`. Treat raw
+fixture logs as private even though only synthetic accounts/documents are used.
+
+The client Dockerfile pins commit `346fc285198908c47a2ee9db7b9adb53d5e88c3c`
+and verifies its source archive SHA-256 before compilation. The Java image builds
+this checkout, including local edits, and records its Git HEAD for context; a Git
+HEAD alone does not certify a dirty tree as that released artifact. This tooling
+is outside the production JAR and adds no application runtime dependency.
+
+## Script regressions
+
+With Pester 5 installed, the initializer and cleanup-ownership tests need no Docker
+or network. Disable Pester's unrelated registry fixture on Windows:
+
+```powershell
+$configuration = New-PesterConfiguration
+$configuration.Run.Path = './dev/tests'
+$configuration.Run.Exit = $true
+$configuration.TestRegistry.Enabled = $false
+Invoke-Pester -Configuration $configuration
+```
+
+## Experimental native sign-in
+
+The separate [native sign-in profile](native-auth/README.md) builds an explicitly
+selected upstream candidate and uses container-private TLS trust. It mounts only
+public Caddy configuration and specific protected fixture input/result files.
+It is opt-in, Test-only, and does not change the default released QQQ dependency.
+
+## Continuous integration
+
+The development workflow runs the Pester and PowerShell analysis checks on
+Windows and Ubuntu for every pull request and main-branch push. Ubuntu also runs
+the real 40-job/S3 Docker smoke. The longer experimental native-auth profile is
+an explicit manual workflow option; it is not silently substituted for the
+released dependency baseline.

+# Experimental native Authentik qualification
+
+This optional profile tests an **unreleased upstream QQQ candidate**. It does
+not replace the default released RC.20 TABLE/MinIO development environment,
+install a connector, or qualify the Windows browser callback UI.
+
+From the repository root, with Docker and PowerShell 7.4 or later:
+
+```powershell
+pwsh ./dev/Invoke-Dev.ps1 -Action Test -ExperimentalNativeAuth
+```
+
+The command creates a fresh owned project, builds the pinned sources, runs the
+test, and removes its containers, network and synthetic database volumes in
+`finally`. Protected input and sanitized result files remain outside the
+checkout. Do not print or commit the private input or Compose environment.
+An explicit fresh `-StateDirectory` preserves the same cleanup behavior.
+Persistent `Start` and conversion of an existing standard environment are
+refused for this profile.
+
+The test uses actual Authentik login stages with generated synthetic accounts,
+the standard QQQ OAuth2 code/session/refresh handlers, and the published .NET
+Core PKCE/session client. The provider issues the authorization codes. The
+client receives a real HTTPS callback and stores only the opaque QQQ session
+in process; provider refresh tokens remain on the QQQ server.
+
+The required checks are:
+
+- Ordinary TLS rejects the fixture before its private CA is installed.
+- Actual API discovery advertises the typed native session grant.
+- Authorized real provider login resolves a server-derived native identity.
+- A wrong-Origin cookie request and an authenticated subject without the
+  printing permission are rejected.
+- A logged-out QQQ session cannot be replayed.
+- After the 20-second provider access grant expires, standard QQQ renewal
+  obtains a new provider grant and preserves the principal and tenant.
+- Revoking the synthetic subject's provider refresh grants prevents renewal
+  after the next access-grant expiry.
+
+Success is recorded only when every check passes. A failure report contains
+the stage and exception type, without callback URLs, credentials or response
+bodies. This short renewal test does not prove months of unattended operation.
+
+Printing discovery accepts stable semantic versions in major 2, including
+2.0.0 and 2.1.0, through the same production Core validation and shared major
+gate as the default workload. The experimental upstream API must still be
+exactly 1.9.0 with `nativeSessionLogin`; typed metadata, PKCE, TLS, callback and
+permission checks are unchanged. The native-client image build runs 12 fake-HTTP
+compatibility checks before any provider or fixture input is used.
+
+## Isolation and source pins
+
+The upstream source is
+[`ecf0f550a0357cec6387c2b54efca128a405a629`](https://github.com/QRun-IO/qqq/commit/ecf0f550a0357cec6387c2b54efca128a405a629).
+Its archive checksum is pinned in `Dockerfile.server`. Maven installs the
+development build only into `/candidate-maven` inside the image; no host Maven
+cache or installed runtime is mounted or changed. Printing source is compiled
+against that candidate solely for this test.
+
+The production .NET Core client is pinned to published source
+[`346fc285198908c47a2ee9db7b9adb53d5e88c3c`](https://github.com/QRun-IO/qqq-print-agent/commit/346fc285198908c47a2ee9db7b9adb53d5e88c3c)
+with a checked archive hash. Authentik, PostgreSQL, Caddy, Java and .NET images
+are pinned by digest in the Compose files and Dockerfiles.
+
+Caddy issues the three fixture HTTPS hostnames using its private local CA.
+`skip_install_trust` prevents automatic trust installation. Only the public
+root certificate is copied to the Java and .NET containers' trust stores;
+ordinary chain and hostname validation remain enabled. CA private keys stay
+in the TLS container's owned volume. No Windows or browser trust store changes
+occur. See [Caddy's local HTTPS documentation](https://caddyserver.com/docs/automatic-https#local-https).
+
+The HTTPS callback receiver is internal to the Compose network. It is separate
+from the installed connector's private URI callback. No callback host port is
+published. The profile mounts public Caddy configuration and the two specific
+private input/result files, rather than a host home or credential directory.
+
+The QQQ fixture uses fresh standard session, redirect-state and encrypted
+refresh-token tables. Its customizer maps the verified provider's synthetic
+`printing_admin` group to the existing native permission. It creates no device
+pairing, job, print operation or fabricated user session. Released RC.20 lacks
+the native-session grant; this experiment must stay opt-in until an appropriate
+immutable upstream tuple is published and separately adopted.
+
+## Recorded local qualification
+
+On 2026-11-01 the full disposable profile passed all eight checks and exited zero.
+Independent inventory confirmed zero owned containers, volumes and networks after
+cleanup. This is evidence for the pinned experimental tuple above, not adoption
+into the default released runtime or installed Windows UI acceptance.
+
+A fresh run against server source `3592dec` (printing API 2.1.0) and the reviewed
+probe compatibility correction also passed all eight checks on 2026-11-01.
+All source files matched the pre-run hash manifest through completion, and
+independent cleanup again found no owned containers, volumes or networks.
+The native image's 12 discovery checks and default workload's nine checks pass.
+The unreleased upstream and installed-browser limitations above still apply.

+# Operator catalog and queue media
+
+This source adds native printing extension 2.3.0 (2.2.0 is the rendering extension and carries no media negotiation). Publication and Windows media
+agent qualification are pending. Existing administrator and device routes keep
+their permissions; this is an additive operator API, not a device bearer API.
+
+Hosts grant `printing_operator` and the `printing_tenant` security key. The native
+`printingSubmit` process remains the domain write permission. Current device and
+printer table/record security, credential scopes and client-channel ceilings apply
+on every operation. Generic job/command history, table writes, enrollment and
+device management remain administrator-only. Hosts may add destination locks.
+Native callbacks cannot replace the initiating actor, session, instance, service
+or row-security context. Submission rechecks current process, credential, channel
+and destination authority after loading/storage callbacks and before commit.
+The backend process is hidden and has no base64-entry form. Echo obtains its user
+selections from the catalog; backend metadata also references native printer and
+format possible-value sources.
+
+- `GET /qqq/v1/qbit/printing/operator/printers?limit=50&after=...` returns at most
+  200 authorized approved/exposed printers, in stable printer-row-ID order. The
+  opaque next cursor advances over at most `limit` candidate rows even if parent
+  device security hides every candidate. Continue until `nextCursor` is null.
+- `POST /qqq/v1/qbit/printing/operator/jobs` accepts `requestId`, `printerRowId`,
+  `title`, `format` (`PDF` or `ZPL`), `contentBase64` and optional `options`. The
+  native printer row determines the device and opaque Windows queue identity.
+  `requestId` is 1–128 characters from letters, digits, `.`, `_`, `:`, `-`.
+  The authenticated actor and tenant scope the stable key; callers cannot supply
+  actor identity or an internal idempotency key. The response is the existing job
+  receipt after durable commit. Changed requests conflict instead of reprinting.
+- `GET /qqq/v1/qbit/printing/operator/requests/{requestId}` returns only that
+  actor's exact accepted request, or 404. It does not enqueue, read document bytes,
+  or initialize settings. Current destination read authority remains required;
+  later loss of exposure alone does not erase the acceptance receipt.
+  Lookup checks the original accepted native printer-row ID. Deleting that row
+  and creating another with the same device/queue pair does not transfer history.
+
+Each catalog entry has `printerRowId`, `deviceId`, `printerId`, effective `name`,
+`deviceName`, `status`, `formats`, `mediaProfiles`, and optional `description` and
+`location`. These names are presentation; the stable row identity selects a queue.
+
+Media profiles report actual Windows queue defaults. Their typed facts are `id`,
+`revision` (lowercase SHA-256), `name`, `widthMicrons`, `heightMicrons`, `dpiX`,
+`dpiY`, `source: WINDOWS_QUEUE_DEFAULT`, `applyMode: DRIVER_DEFAULT`. Unknown or
+unsupported driver facts produce an empty list. The initial client reports one
+configured default; the wire bound is 32. Dimensions are 1–2,000,000 microns and
+DPI is 1–9600. Names are at most 512 characters. Unknown additive reported facts
+are ignored when canonicalizing; known required facts remain validated. Arbitrary
+page-size values are never interpreted as a Windows stock change.
+Profile and selection IDs share the protocol's 128-character URL-safe ID bound.
+
+Select exact reported media with `options.mediaProfile: {id, revision}`. The
+selection is immutable job intent and accepts no extra fields. New submissions
+reject stale/missing profiles before admission/storage writes; exact accepted
+replays remain accepted. The capable Windows agent rechecks its actual current
+default before spooling. Selected-media dispatch requires the current agent
+capability `printer-media-v1`, including after reconnect/downgrade. Legacy
+inventory without profiles clears stale media facts. Omitted selection preserves
+ordinary existing queue behavior. Paper-width/height overrides remain unsupported,
+including when a media selection is supplied.
+
+Generated/retained source authorization belongs to the configured source owner.
+The retained facade shares this operator permission and destination boundary; it
+preserves its atomic accepted source/actor/request binding. Barcode fit and
+encoding remain the renderer's job.
+
+`QUEUED` is durable acceptance; `SPOOLED` means spooler acceptance. Neither is
+physical output confirmation. These tests use synthetic bytes and no real printer.

+# Server qualification — 2026-11-01
+
+The published server **0.3.0-rc.1** and published Windows **0.3.1-rc.1** Core runtime
+completed the following isolated qualification. No live server, installed service,
+real document, physical printer or external cloud bucket was changed.
+
+## Network workload
+
+These measurements describe the earlier released-artifact fixture runs. The
+portable [Docker developer tooling](../dev/README.md) records its own per-run
+measurements and includes separate default smoke and opt-in burst commands.
+
+The existing Java/.NET interoperability fixture was extended with synthetic work.
+It used the actual QQQ table-authenticated host, native session/device binding,
+WebSocket channel, released Core `PrintWorker`, HTTPS-client code over explicitly
+allowed loopback HTTP, file downloads, and WebSocket receipt acknowledgements.
+Only the physical printer and local fixture journal were substitutes. The server
+persisted real SQL jobs and receipts. Admission limits remained enabled.
+
+| Check | Observed result |
+| --- | --- |
+| Burst workload | 10,000 jobs; two tenants; eight devices |
+| Documents | 1,021-byte synthetic ZPL; exact downloaded bytes checked |
+| Completion | 10,000 SPOOLED rows; 30,000 durable event rows; no pending work |
+| Replay | 400 submit and 400 receipt replays; no duplicates |
+| Isolation | Foreign device binding and tenant job access refused |
+| Accounting | Retained bytes exact; no orphan upload rows |
+| Duration | 96.12 seconds including setup; about 104 jobs/second |
+| Maximum backlog | 7,798 committed jobs; final backlog zero |
+| Working set | Server peak 680 MiB; client peak approximately 85 MiB |
+| Cold persistence | 10,000 rows present; read-only check left DB unchanged |
+
+Burst enqueue-to-terminal-ACK latency was p50 43.30 seconds, p95 62.84 seconds,
+p99 64.66 seconds. These values include intentional queue backlog; they are not
+idle notification latency.
+
+A separate **40-job one-at-a-time** run measured:
+
+| Interval | Median | 95th percentile |
+| --- | ---: | ---: |
+| Received notification to claim completion | 8.72 ms | 27.18 ms |
+| Received notification to verified download completion | 29.74 ms | 49.07 ms |
+| Enqueue to durable terminal receipt acknowledgement | 49.65 ms | 76.56 ms |
+
+The fixture does not periodically poll for jobs. A received notification wakes a
+finite claim/drain operation. Liveness PING messages do not query jobs. These are
+HTTP/WS loopback results, **not HTTPS/WSS, remote network, physical print-speed,
+large-document sustained throughput, or long-duration soak qualification**.
+The fixture journal is not the installed Windows SQLite journal; its recovery
+behavior is covered separately by the Windows tests.
+
+## Existing storage path, current release
+
+The existing S3 qualification harness was rerun against this exact published
+server and its unchanged 204-JAR runtime. All **65 checks / six document round
+trips** passed through native QQQ `StorageAction`, `S3StorageAction`, and AWS SDK
+against one disposable local MinIO container. The run includes actual multipart
+upload above 5 MiB, exact length/hash/MIME, tenant namespaces, immutable-reference
+validation, stable replay, completion-age retention, and protection of active,
+failed, uncertain, fresh, foreign and unrelated objects. The owned container and
+its ephemeral data were removed after identity verification.
+
+This is S3-compatible data-plane evidence. It does not qualify AWS IAM, remote
+TLS, bucket policies, versioning/Object Lock, or a configured production storage
+target. The existing platform-specific key-layout binding guard remains required;
+no shared QQQ library or cross-OS migration behavior was changed.
+
+## Repeatable service regression
+
+`PrintingWorkloadTest` is an opt-in file-backed regression, separate from the
+network fixture. It runs 10,000 real service lifecycles through four pooled SQL
+connections, tests replay and tenant pagination, verifies exact event/byte counts,
+and closes every connection before reopening without schema initialization.
+
+```powershell
+./mvnw.cmd -Pui-demo -Dprinting.qualification.load=true verify
+```
+
+The protocol fixtures must be present at the usual sibling checkout; alternatively
+set `-Dprinting.protocol.fixtures=/path/to/reviewed/fixtures`.
+The full gate passed **119 tests, zero skips and zero Checkstyle violations**.
+A subsequent exact event-count assertion improvement passed its focused workload
+rerun. Default builds skip this explicit workload test; ordinary regression tests
+remain unchanged. The separate development workflow runs cross-platform script
+checks and the real 40-job/S3 Docker smoke on pull requests and main pushes; its
+experimental native-auth run is manual. Hosted results must be checked on the
+submitted commit. No application implementation or dependency changed.
+
+## Scope boundaries
+
+The user's current development/test target is local Docker. AWS/account/IAM or
+remote deployment provisioning is not a prerequisite for this change.
+
+The separate [experimental native-auth profile](../dev/native-auth/README.md)
+passed real Authentik login, denied-user/wrong-Origin checks, logout, short token
+renewal and provider revocation using container-private HTTPS and the pinned
+unreleased QQQ API 1.9 candidate. It does not upgrade this regression's released
+RC.20 dependency or qualify the installed Windows browser callback. The workload
+and S3 measurements above remain HTTP/WS and MinIO evidence, respectively.
+
+Long-duration soak, mid-session account/role changes and sustained physical
+throughput remain separate from these bounded tests and previously confirmed
+individual physical prints. No application implementation, dependency or
+published package version changes in this test/developer-tooling change.

+# Real-time printing host integration
+
+Release candidate [0.3.0-rc.1](https://github.com/QRun-IO/qbit-printing/releases/tag/v0.3.0-rc.1)
+implements printing extension **2.0.0** (wire envelope v1). Upgrade the server
+before the matching Windows connector; a real-time connector rejects a server that advertises only extension
+1.x. There is no timed job/control polling fallback.
+
+## Connection and authorization
+
+The Windows service initiates `wss://<qqq-origin>/qqq/v1/qbit/printing/device/realtime`
+using subprotocol `qqq-printing.v1`. No facility listener or inbound firewall rule
+is required. Plain WebSocket is allowed only for explicit loopback development.
+Configure the cloud ingress to forward WebSocket upgrades, preserve the original
+HTTPS origin and allow the configured heartbeat interval/timeout.
+
+The service discovers authentication through the QQQ UI/UX API and uses the
+standard current QQQ session, client channel and approved bound-device proof.
+Credentials are not URL parameters. Device proof does not replace the user's
+authority. The server validates the current session, user/tenant, channel policy
+and operation permissions; socket establishment does not grant permanent rights.
+Session expiry, logout, revocation and permission denial require correction or
+sign-in through the configured QQQ provider. Reconnect cannot bypass them.
+
+Register the route provider alongside the ordinary native QQQ endpoints:
+
+```java
+server.withAdditionalRouteProviders(List.of(existingHttpRoutes,
+   new PrintingRealtimeRoutes(printingService)));
+```
+
+Use the **same PrintingService instance** in the QBit configuration and route
+provider. `PrintingLocalHost.configure` shows the complete launcher integration.
+The native HTTP claim route requires a connected socket that has applied the
+current desired state and settings. Registering just the older HTTP provider is
+insufficient. Close the provider when its host stops.
+
+## Independent control and document lanes
+
+The socket carries small JSON state, commands, inventory, heartbeats, job events
+and durable receipts. A job notification triggers a finite HTTP claim drain;
+an empty queue waits for another push. No timer repeatedly fetches claims or
+commands. Heartbeats, session renewal and reconnect backoff are lifecycle work,
+not job polling.
+
+Documents use separate outbound same-origin HTTPS transfers. The Windows service
+streams them to protected staging files and checks declared length and SHA-256
+before native submission. The socket reader remains active during a slow download.
+PDF rendering and ZPL spooling receive the verified file rather than a base64
+payload in the control pipe. Limits bound staging, messages and concurrency.
+
+Receipts remain on disk until the server acknowledges their committed IDs. A
+reconnect resynchronizes current state/settings and replays retained receipts.
+An interrupted native submission remains uncertain and is never automatically
+reprinted. A successful spooler submission does not prove paper physically printed.
+
+## Native administrator settings
+
+Printing home links to two standard QQQ processes. They enforce current
+administrator and tenant access on the backend as well as in metadata:
+
+- **Printing connection and limits**: PDF/ZPL size, copies, staging space,
+  concurrent downloads/prints, bandwidth, request/download timeouts, heartbeat,
+  reconnect backoff/jitter, acknowledgment timeout and control message queues.
+  Defaults are 100 MiB PDF, 20 MiB ZPL and one download/print lane. Saved policy
+  changes have a durable revision and are pushed to connected devices.
+- **Printing queue and storage limits**: device/tenant outstanding counts and
+  bytes, retained bytes, hourly allocations and printer counts. New admissions
+  use the persisted policy inside their SQL transaction. Reducing limits preserves
+  existing jobs and history; it does not silently remove documents.
+
+Fields use readable MiB/GiB/seconds with exact conversion, required values and
+cross-field validation. Unsupported client ceilings fail explicitly rather than
+silently clamping. Storage retention remains in the separate native retention
+process, with a one-year default.
+
+HTTP ingress/body limits remain host-owned. The local host derives its upload
+body ceiling at startup from the persisted document limits (including base64
+expansion for legacy submission). Raising a document limit above the running
+transport ceiling requires a host restart or corresponding production ingress
+configuration. Download streaming does not base64-expand documents.
+
+## Host ownership and deployment boundary
+
+Commit wakeups are emitted after SQL commit. A subscription exists before initial
+state reconstruction, closing the empty-claim/reconnect notification race.
+`PrintingRealtimeBus` is an explicit host-owned notification and connection
+ownership seam. The default implementation is in-process; this source does **not**
+provide a distributed broker or claim tested multi-node production support.
+
+Use one writer/application host with its configured service/bus. Multiple route
+providers sharing that explicit in-process bus fence a device's prior connection.
+A multi-node deployment needs a host-provided shared implementation preserving
+both post-commit notifications and single-channel ownership, and its own
+qualification. Separate independent service instances do not magically publish
+notifications to one another.
+
+The existing `/printing/v1` routes remain explicit legacy diagnostic compatibility.
+They are not a real-time fallback and cannot authorize a native bound device.
+The full message and settings contract is in
+[the shared protocol](https://github.com/QRun-IO/qqq-print-protocol).
+
+## Printing API major upgrade
+
+The extension is **2.0.0** because native HTTP claims now require a synchronized
+WebSocket. A published 1.0 HTTP-only connector no longer meets that precondition;
+this is a breaking behavior change even though request bodies remain wire v1.
+The QQQ framework API `/qqq/v1`, extension path `/qbit/printing` and WebSocket
+subprotocol `qqq-printing.v1` remain unchanged. Upgrade server and client together;
+an older client must report upgrade-required instead of using polling fallback.

+# Retained print acceptance (additive candidate)
+
+This optional Java integration preserves the existing native generation print
+process and the existing printing queue. It adds no device wire fields or REST
+routes. It is disabled until the host supplies
+`PrintingQBitConfig.withRetainedSourceAuthority`. Current `printing_operator`
+(or administrator) authority and native tenant/device/printer record checks
+remain mandatory. Submission also requires the shared `printingSubmit` process
+permission. This grants no device management or generic job-history access.
+
+## Public contract
+
+`RetainedPrintFacade.Request(requestId, sourceLocator, printerRecordId, title,
+optionsJson)` contains no actor or asserted source binding. Request IDs use
+`[A-Za-z0-9._:-]{1,128}`, including owner namespaces such as `echo:<scanId>`.
+`submit` derives the signed-in native actor and returns an immutable
+`Acceptance`; it includes the exact source, job/event identities, tenant,
+initiating actor, destination, title and normalized options JSON, including any
+`mediaProfile` ID/revision. `find` authorizes the same complete request and
+returns that acceptance, null for observed absence, or a conflict for an
+unresolved upload reservation. Reuse the same request identity after a lost
+response. Never convert an unavailable lookup into absence or create another
+intent automatically.
+
+The host-configured `RetainedPrintSourceAuthority.resolve(locator, requestId)`
+must authorize the current native actor, source association and currently
+eligible immutable version. It returns `SourceReference(owner, opaqueReference,
+sha256, sizeBytes, mediaType)`. `opaqueReference` is at most 4000 Java
+characters, stable and canonical under that owner's rules; printing does not
+parse owner-specific fields. The optional Record Files adapter must encode its
+complete version/source/generation-request/initiating-actor/tenant tuple and
+compare generation's committed receipt. Accepted MIME types are
+`application/pdf` and `application/vnd.zebra-zpl`; the current configured
+PDF/ZPL limits apply before the byte read, within the existing integer-length
+storage ceiling. `read(reference, requestId)` must enforce the same current
+permissions and return only those exact bytes. Hash/length verification remains
+in printing's existing submission path. Do not supply arbitrary source
+authorities per request or reconstruct a user session.
+
+Source admission remains the owner's policy. An explicitly configured published
+template may qualify generated output without a per-label release dialog;
+external-upload quarantine is unchanged. Printing performs no automatic release
+and creates no human-release audit. `resolve` must be read-only and must not
+invoke a generation reconciliation operation that can generate or dispatch work.
+
+Source/destination checks surround owner callbacks and precede acceptance.
+Submission refuses an ambient QQQ transaction: queue acceptance is independently
+committed and cannot be rolled back by a caller's transaction. Submission also
+enforces the native job-table credential and channel mutation ceilings; lookup
+uses the corresponding read ceilings without granting generic table access.
+`find` calls no byte reader, submission or event writer, and its option
+normalization cannot initialize settings. It reauthorizes the source and
+destination records, then compares the exact accepted intent; a later exposure,
+media inventory or dispatch-limit change does not reinterpret that historical
+intent. A later permission loss may deny returning a receipt whose job already
+committed; it never authorizes a replacement job.
+
+## Persistence and replay
+
+Existing `printing_job` gains nullable `retained_actor_id`,
+`retained_binding_json`, and `accepted_event_id`. Existing `printing_event`
+gains nullable `event_origin`. `initialize` applies additive upgrades; old
+jobs/events remain unbound/unclassified. None of these internal fields are added
+to the device `JOB_COLUMNS` DTO or native table metadata.
+
+Submission and exact lookup both use the existing tenant admission lock, so an
+in-flight inline acceptance cannot be mistaken for absence. The unique
+`(tenant_id, idempotency_key)` serialize submissions. Retained keys use
+`retained:` plus the request ID. Ordinary/bound collisions refuse. Complete
+normalized intent includes actor, owner reference, content hash/length/media,
+destination, title, options and tenant. The existing storage reservation/orphan
+path is reused; it may commit an upload reservation before writing object
+storage. The final job, retained binding, and server acceptance event commit
+together. Failed acceptance-event insertion rolls back the job. Rollback or
+orphan-cleanup failures are suppressed onto the original failure rather than
+replacing it. Existing initialization widens legacy 300-character titles to
+1024; the bound title preserves exact whitespace and Unicode and is compared on
+replay. Acceptance-event JSON has `type=ACCEPTED`, `origin=SERVER_ACCEPTANCE`,
+`status=QUEUED`; it does not claim device receipt or physical output.
+
+This is atomic acceptance binding inside printing, not a distributed transaction
+over the retained owner's authorization database. Deployment still owns durable
+database/storage settings, bounded provider calls and current session policy.
+
+## Committed observations
+
+`observation(requestId, eventId)` reads only an exact committed event joined to
+the accepted job. New ordinary device events are stamped `DEVICE_OBSERVATION`;
+pre-upgrade unclassified events and server acceptance events cannot be returned
+as device evidence. The current native operator must have current device/printer
+row authority and satisfy the job credential/channel read ceiling. Before
+returning any source metadata, printing calls the configured owner's
+`authorizeObservation(source, requestId)` under the current reporter session,
+then rechecks the current ceiling and destination authority. Its default
+implementation refuses; adapters must explicitly implement their current
+source-observation policy. This callback does not grant content access or
+impersonate the initiating actor. This is an operator-authorized observation
+lookup, not device enrollment or permission to forge reporter identity. The
+optional RF authority adapter must preserve initiating actor separately from
+current reporting actor and map only supported stored states. Neither `SPOOLED`
+nor `SPOOLER_COMPLETED` proves physical output.
+
+## Verification scope
+
+The tests use real H2 transactions and native QQQ row authorization with
+synthetic printers. They never contact a device or emit physical output.
+Coverage includes commit-then-throw acknowledgment loss, concurrent exact
+replay, held-admission-lock lookup, mutation ceilings, owner observation
+refusal, callback revocation, exact content hash/length, configured document
+bounds, title upgrade/replay, read-only historical lookup and original-error
+preservation when rollback fails. Qualification of this adopted source is
+recorded in the session notes; the older peer candidate's test result is not
+evidence for this revision. Cross-QBit integration remains a separate gate. No
+release, install, shared-cache substitution or runtime migration has occurred.

 # Session state — 2026-10-31
 
+## Echo operator/media and retained-source candidate — 2026-11-01
+
+The isolated Echo candidate adds native printing extension **2.3.0** (after the protected-main 2.2.0 rendering extension) on the
+unchanged product `0.4.0-SNAPSHOT` and QQQ `4.1.0-RC.20` dependency tuple.
+`printing_operator` permits the authorized printer/media catalog and exact-actor
+submission/reconciliation without device administration or general job history.
+Reported Windows queue-default media is revision-bound; clients without the current
+`printer-media-v1` capability cannot claim jobs carrying a media selection.
+
+The opt-in retained-source facade shares that boundary and commits immutable
+source/actor/destination/intent plus its server acceptance event inside the existing
+queue transaction. Its owner adapter is required and default-deny; read-only lookup
+never generates content or submits a replacement job. See
+[operator catalog](OPERATOR-CATALOG.md) and
+[retained acceptance](RETAINED-PRINT-FACADE.md) for exact contracts and limits.
+
+Protected main advanced to a rendering release at printing 2.2.0 (header/footer
+chrome, content sections, render-to-PDF) while this candidate was qualified, so the
+operator/media/retained feature was merged onto it and moved to 2.3.0. The earlier
+183-test gate is historical evidence of the pre-merge source only.
+
+Observed after the merge, locally: the OpenAPI contract was regenerated with the
+existing explicit update switch and its 1.0.0 compatibility baseline hash was
+unchanged. A sandbox full verify reported 188 tests with 11 loopback setup errors and
+no assertion failures (environmental). The first actual-user full verify reported 188
+tests, no assertion failures and **one error**:
+`PrintingRealtimeTest.mediaCapabilityIsReplacedOnEveryAuthenticatedHello` failed
+only when JUnit removed its temporary directory. Cause: `PrintingRealtimeRoutes.close()`
+shut its executor down without waiting, so a channel drain still running after the
+host stopped queried a deleted file database and recreated it empty. The fix waits
+(bounded) for running drains, with regression
+`closeWaitsForChannelWorkersAlreadyRunning`. After it, five consecutive focused
+`PrintingRealtimeTest` runs passed (4 tests each, no empty-database warnings) and the
+full `-Pui-demo verify` passed: **189 reported, 188 executed, one intentional opt-in
+workload skip, zero failures/errors, zero Checkstyle violations**; the source-header
+guard over 146 tracked files and staged whitespace checks passed. The earlier failing
+logs are preserved. This is local evidence only: hosted CI on the signed candidate
+head, publication and cross-QBit consumer qualification are pending. The suite runs
+against synthetic H2 fixtures; no live database, connector, printer or shared
+artifact has been changed. The
+experimental API 1.10 used by Echo is a separate owner-controlled tuple and has not
+been substituted for this candidate's qualified RC.20 dependencies. Publication,
+cross-QBit consumer qualification and any physical output remain separate gates.
+
+Native destination and storage callbacks cannot carry stale actor, session,
+credential, channel or row authority into admission, replay or commit. Receipt
+lookup authorizes the original stored printer-row ID; a replacement row with the
+same device/queue pair cannot inherit earlier acceptance history. The regressions
+reproduce both prior paths, verify denial and rollback, and preserve authorized
+read-only observation after the original queue loses exposure. Media IDs are
+bounded to the shared 128-character contract; long device display names remain
+supported without truncation.
+
+## Local Docker development — 2026-11-01
+
+The optional native-auth probe now shares production Core discovery and the
+default workload's printing-major-2 gate, accepting stable 2.1.0 while retaining
+the exact experimental API 1.9/native grant requirement. Its previous exact-2.0.0
+check reproduced a rejection before the fix. Native and default client image
+builds pass 12 and nine fake-HTTP compatibility checks respectively, with zero
+warnings/errors. One fresh provider run against server source `3592dec`
+(printing API 2.1.0) and the reviewed probe correction passed all eight checks.
+All source hashes remained unchanged through completion; independent cleanup
+found zero owned containers, volumes and networks. No installed runtime,
+physical printer or host trust setting changed.
+
+The developer tooling is published on `main` through [PR #21](https://github.com/QRun-IO/qbit-printing/pull/21),
+merged as `3592decba8087439aff5d1b75a9726c72f460cb9`; its tree matches tested
+head `def8d961f3d82a1235f8e45ffbeacb0fbe79c421`. The final hosted
+[development run](https://github.com/QRun-IO/qbit-printing/actions/runs/41324370247)
+passed the actual 40-job HTTP/WS smoke and 65 S3 checks, nine pinned-Core discovery
+compatibility cases, and all 33 script tests on each of Windows and Ubuntu.
+The [Java run](https://github.com/QRun-IO/qbit-printing/actions/runs/41324370253)
+reported 133 tests: 132 executed, one intentionally skipped opt-in workload test,
+zero failures/errors, and zero Checkstyle violations. That workload separately
+passed on the combined source. These are development-tooling publication results,
+not a server release or live runtime upgrade. The experimental API 1.9 candidate
+remains opt-in and is not adopted into the released application dependencies.
+
+The current qualification scope is local Docker only. The new `dev/Invoke-Dev.ps1`
+provides owned Start/Test/Stop commands for a native QQQ TABLE host, dedicated
+MinIO storage and optional real Authentik/PostgreSQL. Source images and the client
+Core archive are pinned. Generated credentials stay in private state outside the
+checkout; no installed connector, live database or physical printer is used.
+
+Portable Docker checks passed: the default 40-job smoke, 65 actual QQQ S3 backend
+checks, and an opt-in 10,000-job/two-tenant/eight-client run with 30,000 durable
+server receipts and 400 submission plus 400 receipt replays. The burst completed
+in 147.856 seconds (about 67.63 jobs/second); its enqueue-to-ACK p95 was 32.984
+seconds while work intentionally queued. This is HTTP/WS with a fake file printer
+and a simple fixture client journal, not TLS, hardware or a long soak claim.
+
+Native TABLE login, identity, frontend asset and logout passed. Real Authentik
+configuration/discovery passed; a registered redirect continued to login and the
+otherwise-identical unregistered redirect was rejected. The released RC.20 host
+still advertises API 1.8 without the native session grant: browser login, renewal
+and the Windows callback are not established by these checks. All owned test
+containers, volumes and networks were removed. Lifecycle/bootstrap regressions
+passed 28 cases including experimental-profile refusal and diagnostic-redaction
+checks; scripts passed parser and PSScriptAnalyzer checks.
+
+The separate opt-in native-auth profile passed eight actual checks against the
+immutable upstream API 1.9 candidate `ecf0f550a0357cec6387c2b54efca128a405a629`:
+ordinary TLS refusal before container-only CA installation, typed-grant discovery,
+real Authentik login through the production Core PKCE client, wrong-Origin cookie
+rejection, denied-user permissions, logout replay refusal, server-side renewal
+after access-token expiry and denial after provider refresh-token revocation.
+The final run exited zero and all owned containers, volumes and networks were
+removed. Earlier failed fixture attempts remain in private evidence; their fixes
+were standard-flow readiness/binding, bounded provider redirects and the correct
+Authentik CSRF header. No authentication check was disabled.
+
+This experimental candidate is not the default released RC.20 runtime or a
+published production dependency upgrade. Container HTTPS and automated real
+provider flows do not qualify the Windows browser callback UI, host trust,
+months-long operation or physical printing. See [local development](../dev/README.md),
+[provider limits](../dev/AUTHENTIK.md) and [native qualification](../dev/native-auth/README.md).
+Earlier release checkpoints below are historical. This developer-tooling merge
+did not publish a new server product release or change the live paired runtime.
+
+## Opt-in service workload regression — 2026-11-01
+
+The combined test/development change also includes a 10,000-job, two-tenant,
+eight-lane file-backed service regression with replay, exact accounting,
+pagination and cold reopen checks. It is opt-in and never accesses a printer.
+The original isolated full gate passed 119 tests with zero Checkstyle violations;
+the final exact receipt-count assertion passed its focused rerun. Its source is
+unchanged when integrated here, and the combined checkout passed one focused
+workload test with zero Checkstyle violations. The earlier released-artifact
+network run and
+40-job idle latency measurements are recorded in
+[qualification evidence](QUALIFICATION-2026-11-01.md), separately from the portable
+Docker run above. No runtime source, dependencies or version changed.

 ## Active device controls and standard QQQ authentication
 
 Implementation is in the isolated device-controls worktree. Native device/table actions support pause, resume, disconnect, reconnect, revoke, inventory refresh and queued-job clearing; job records support exact owned Windows-job cancellation. Related printers, jobs, pending queue and bounded command history are registered. Derived status separates connection presence, desired state and observed revision. Domain writes use current QQQ permissions; clearing a queue checks every affected job before the transactional mutation.

Commit notifications and finite event-triggered claims, bounded concurrency, persistent receipts and reconnect reconciliation are being implemented. Tenant administrator forms expose document, transfer, connection, queue/rate/printer/storage limits. Default PDF limit100MiB, ZPL20MiB; both configurable.

A private actual.NET/Java fixture passed13 functional checks with25MiB content, durable receipt replay, channel replacement and sign-out denial; its initial fixture JVM needed explicit maintenance-thread shutdown handling, so this is not installed lifecycle qualification.
