Merge pull request 'perf: keep the access fingerprint for the request and read rule rows once per change' (#41) from perf/request-scoped-resolver-and-cached-rules into develop

Core asks the field access resolver for its fingerprint before every field
decision (FieldAccessHelper.getDecision), that is once per field of every
record of a result and of every table in the metaData document. Each call
recomputed it: a JSON key, a permission lookup for every table, another JSON
document and a digest. Core also asks for the retention rules of a field on
every audited field and every filter criterion, and each question was a
query.

- getAccessFingerprint keeps its value in the request context (QContext) and
  returns it while the session, its permission set, the channel, the policy
  and classification versions are unchanged and no active break-glass grant
  has expired. Nothing outlives the request.
- RetentionRules.active answers from the active rules the runtime read once
  (SecuredDataRuntime.activeRetentionRules). A rule write clears them after
  commit; a thread that edits rules inside a transaction reads its own edits.
- Policy, classification and retention changes are announced on QQQ's cluster
  bus (ClusterCaches, memo-invalidate), so every node reads again. Before,
  the versions were node-local and another node kept old rules until restart.
- No node uses rule rows older than 30 seconds without reading them again
  (the safety net for a lost event).
- A read that fails throws and replaces nothing: never an empty rule list.

Measured in one JVM with GG Forge's composed instance (222 tables, secured
data and collaboration wired, in-memory backend, platform administrator),
released 0.1.0-RC.4 against this change, same machine, back to back:
metaData request 866.6 ms to 125.3 ms (930 MB to 74 MB allocated, 96 to 34
queries); a 300-row list 1,566 ms to 24 ms; a 27-row list 174 to 230 ms down
to 13 to 17 ms; queries per list 23 to 8.

 ## [Unreleased]
 
+### Fixed: access-log lifecycle
+- The access-log worker and JVM shutdown hook hold the logger weakly, so an instance the host drops (tests, reloads) can be collected; its worker stops at the next tick.
+- `withRegisterShutdownHook(false)` for hosts that call `SecuredDataRuntime.close()` themselves; `SecuredDataAccessLogger.isWorkerRunning()`.
+- Virtual (computed) fields resolve through the table classification instead of throwing (#18).
+- Idle access-log ticks open no context, so the worker never validates an unfinished host instance, and a failed tick no longer stops the worker (#18).
+
+### Changed: UI API 1.6.0
+- UI API extension secured-data 1.1.0 (requires QQQ 4.1.0-RC.15, UI API 1.6.0): operationIds, standard error responses with BasicErrorResponseV1, extension tags, and retained SecuredDataErrorV1 schema deprecated since 1.1.0.
+
+### Changed — direct core field access and audit protection
+- Remove all #1172/#1182 stand-ins and reflective bridges; use core field-access, classified-value token, audit protection, wipe flag and shredded-event APIs directly.
+- Register the resolver, key source and audit protector through core supplemental metadata.
+- Run core field-access integration and retention proof tests unconditionally.
+- Pin QQQ to `4.1.0-RC.7`, which ships field access (#1172) and audit value protection (#1182); all core stand-ins and reflective bridges are removed.
+
+### Changed — RC.6 migration
+- Pin QQQ to 4.1.0-RC.6; use released classification, client-channel and table-feature APIs directly.
+- Fold UI API code and tests into the main build and remove the profile and reflective registration.
+- Remove released-API stand-ins and the local contract assertion facade; retain #1172 field-access stand-ins with RC.7 removal markers.
+
+### Added: phase (f) retention and wipe
+- Retention rules, wipe markers, legal holds, wipe runs and a hidden, locked audit-key table, with the `secured_data.retention` permission and a "Retention rules" navigation entry.
+- Actions NULL_WITH_MARKER, OVERWRITE_TEXT, KEYED_HASH, DELETE_RECORD and ARCHIVE_THEN_WIPE (host `ArchiveSinkInterface`), with validation and low-entropy refusal.
+- Atomic wipe batches (fields, markers, key deletions, audits, access log and run row in one rollback-capable transaction), per-record and per-table legal holds, a Review/Result "Run wipe now" process and a daily scheduled run.
+- Per-record-field AES-GCM wrapped DEKs (AAD-bound) for crypto-shredding of audit tokens, `CHANGED_ONLY` audit treatment, and the audit-value protector.
+- App-home warning when known backup retention exceeds a rule's `age_days`; `withBackupRetentionDays` and `withArchiveSink` options; README retention section and the backups residual risk.
+- Tests: all actions, holds, rollback, Review/Result, schedule, permissions, wrap/unwrap, and the section 15 canary and wipe-proof tests.
+
+### Fixed
+- The key source returned a DEK array it then zeroed; it now returns copies, with a regression test.
+
 ### Added
 
+- Phase (e) configurable reveal-median, distinct-record and exact-match anomaly detection, with system access-log counters, bounded daily median caching, per-user/day alerts, and flags retained without an alert sink.
+- Break-glass start and capped-reveal anomaly flags alongside the existing alerts.
+- One Secured Data app home with six live KPIs, six full-width responsive lists, filtered View all links, theme tokens, compact dates, clamped text/tooltips and explicit empty states.
+- Transaction-aware, value-free policy/classification change audit rows from post-write customizers and two access-log indexes for anomaly/home queries.
+- Boundary, alert, home data, rendering and navigation tests plus a synthetic Next demo harness for coordinator screenshot capture.
+
+- Phase (c) HTTP-independent reveal options, reason validation, UTC daily limits, grants, audit links, cap alerts and assistant refusal.
+- Five-second per-user grant cache with immediate invalidation and read-time expiration.
+- Start/End break-glass table and record actions, streamed Review/Result summaries, owner/admin authorization, scheduled expiration, alerts and optional admin bell notification.
+- Caller status and the versioned `secured-data` UI API extension behind the temporary `uiapi` Maven profile, with committed OpenAPI and contract/HTTP tests.
+- Contingent classification field picker support for snake_case and camelCase table selections; unknown-table rejection.
+- Memory and real-core coverage for reveal, break-glass, record locks and expiry. Reason columns support 500 characters; existing RDBMS installations must widen the three `reason` columns to VARCHAR(500).
+
 - Phase (b) secured-data classification, policy, reveal-grant, break-glass and insert-only access-log tables, metadata, permissions, pickers and app navigation.
 - Versioned classification and policy resolution with channel caps, table features, break-glass expiry and access fingerprints.
 - Bounded asynchronous value-free logging, HMAC search fingerprints, rate limits, entropy rules and enumeration alerts.

-RC.5 contains AI exposure metadata, the alerts producer SPI and the tables picker. It does **not** contain field-access enforcement, `DataClassification`, classification properties on AI metadata, client channels, or table-feature permissions. Jar contents and embedded sources were inspected locally (`jar tf`; Git's `unzip` could not run in the Windows sandbox).
+Core classifications, AI metadata, client channels, table-feature permissions and UI API extension points are used directly. The UI API and its contract test are part of the main build; the contract test calls `UiApiContract` directly.
 
-Missing APIs live under `com.kingsrook.qbits.secureddata.standin`, with `STAND-IN` removal markers. `CoreFieldAccessBridge` registers a dynamic proxy only when core's `FieldAccessResolverMetaData` exists. It converts decision record components and event enums by name. On RC.5 it logs one INFO that enforcement requires RC.6+; installing this QBit on RC.5 **does not enforce field tiers**.
-
-`CoreMetadataBridge` promotes temporary classifications into core AI metadata when supported, registers the channel wall and table features reflectively, and uses core feature-permission checks when present. A missing API is supported; a present but incompatible API fails startup. The public classification API temporarily returns the stand-in `DataClassification` because the core enum is absent from RC.5. At RC.6, move these imports to core and delete the adapters/stand-ins.
+Field access (#1172), classified-value tokens and audit-value protection (#1182) use core types directly. The producer registers the resolver, key source and audit protector through core supplemental metadata; QQQ core enforces field tiers.

 Both table features are registered for **all tables**: `secured_data_full` (Secured data: full) and `secured_data_reveal` (Secured data: reveal). This deliberate catalog choice supports new admin classification rows without a restart.

+One daemon worker drains a bounded queue as a system session. Enqueueing does not wait for persistence. Full queues and failed writes warn without values and increment `getDroppedCount()`. The app can expose this counter later. Explicitly call the instance's `SecuredDataRuntime.close()` at host shutdown; a JVM shutdown hook also drains accepted rows unless `withRegisterShutdownHook(false)` turns it off (hosts that close the runtime themselves). Neither the worker nor the hook holds the instance strongly: an instance the host drops (tests, reloads) can be collected, and its worker stops at the next tick. An abrupt process crash can lose queued rows.
 
 Flagged rows raise the optional alerts producer signal `secured_data.enumeration`, deduplicated by `secured_data.enumeration:<user>:<table>.<field>:<UTC date>`. RC.5 already provides `QAlerts`; without an installed sink it logs the signal. Its catalog validator rejects underscores in type names, so this mandated type is sent through the producer without catalog registration until that core restriction is reconciled. No values or fingerprints are sent to the alert sink.
 
+## Reveal and break-glass
+
+`new RevealService().options(tableName, fieldName)` describes the reason choices, free-text rules, duration and remaining allowance. `reveal(tableName, primaryKey, fieldName, reason, reasonText)` performs an explicitly permission-enforced Get as the caller before a system read. It returns `value`, core-formatted `displayValue`, `expiresAt`, and `revealId`. Grants and their linked audit rows are system-written; no raw value is copied into the access log.
+
+The effective tier must be REVEALABLE. The chosen granting policy is the row with the highest daily cap (null means unlimited), then the longest duration, then lowest lexical id. Channel-only cap rows never grant reveal settings. A feature/default-based REVEALABLE tier with no granting row uses five minutes and an allowed free-text reason. Limits count grants across all tables for the user in the UTC day. Reason and reason text each have a 500-character limit. A required explanation is accepted alongside a listed reason even if arbitrary free-text reasons are disabled. Capped requests record `REVEAL_DENIED/CAPPED` and raise `secured_data.reveal_capped`; assistant-channel requests record `REVEAL_DENIED/DENIED` and return 403.
+
+Grant lookups cache identifiers and expiration times for at most five seconds per user, check expiration on each use, and invalidate immediately after a new grant. The service serializes cap-check/write and duplicate-session checks within one runtime. Multi-replica deployments must coordinate these operations externally for a globally atomic cap and single active session; the in-process lock is not a distributed lock.
+
+`secured_data_break_glass_start` is a table action, labeled **Start break-glass**, requiring `secured_data_break_glass_start.hasAccess`. Its reason must contain 20-500 characters; duration defaults to 60 minutes and accepts 1-480. Table scope is optional and classification ceiling defaults to PHI. `secured_data_break_glass_end` is a record action with the standard streamed ETL Review/Result screens; ownership/admin authorization is checked at review and again at execution. Neither action is a navigation entry. The current admin-only activity table permissions remain in place; an owner can invoke End using the session id returned by status without obtaining admin access to activity tables.
+
+Start raises `secured_data.break_glass` at core's `HIGH` mapping (`AlertSeverity.ERROR`). End and expiry resolve the same per-session alert. Bell delivery targets holders of `secured_data.admin` through core's optional notification SPI #1125. RC.5 and the installed secure-data snapshot lack that SPI: a clear warning is logged. TODO: switch to a direct notification call when #1125 ships and verify against a notification-capable core.
+
+Configure `.withSchedulerName("yourScheduler")` to register the hidden `secured_data_break_glass_expire` process every minute. Without a scheduler, the host must invoke that process itself. Tier resolution checks expiration independently, so delayed maintenance cannot prolong access. `new StatusService().status()` returns the caller's active session or null, grants used today, and the allowance for each readable REVEALABLE field.
+
+## UI API extension
+
+The `secured-data` extension is version **1.1.0**:
+
+- `POST /qqq/v1/qbit/secured-data/reveal`
+- `GET /qqq/v1/qbit/secured-data/reveal/options?tableName=&fieldName=`
+- `GET /qqq/v1/qbit/secured-data/status`
+
+The producer registers the UI API extension directly. The committed contract is [secured-data.yaml](src/main/resources/openapi/qqq-v1/secured-data.yaml); regenerate intentionally with `-Dqqq.uiApi.regenerate=true`. Contract and HTTP tests run in the normal build.
+
+The classification field picker uses CUSTOM possible values, reading `table_name` or `tableName` from the form's other values. It returns only the selected readable table's labeled fields, returns none without a selection, and rejects an unknown table. TODO: add `dependsOn("table_name")` when the core metadata API supports it.

-The direct suite uses memory and H2. `CoreFieldAccessBridgeIT` is included by Surefire and uses JUnit assumptions to skip unless the actual core resolver metadata is present.

Checkstyle and JaCoCo remain 70% instructions / 90% classes; stand-ins are not excluded.
+The suite uses memory and H2. `CoreFieldAccessIT` runs unconditionally through Surefire and exercises Query/Get, policy tiers, masking, exact matches and outcomes, sorting denial, rate/entropy refusal and the assistant wall. `RetentionProofTest` also runs unconditionally. Checkstyle and JaCoCo gates remain 70% instructions / 90% classes.
+
+## Anomaly monitoring (phase e)
+
+Application REVEAL and queued EXACT_MATCH_FILTER audit writes evaluate persisted access-log counters as system, counting the current row once. Successful reveals flag above three times the user's median across the previous 30 complete UTC days (including zero days), with at least ten reveals today. More than 20 distinct `(table, record)` pairs within the last hour also flag. More than 50 exact-match attempts on one restricted field within the last hour flag independently of enumeration controls. The default rate limit of 20 usually refuses searches first; refused attempts still count.
+
+Break-glass starts and capped reveal refusals also flag. Each raises `secured_data.anomaly` with dedup key `secured_data.anomaly:<user>:<UTC day>` through the optional alerts SPI. Existing enumeration, break-glass and cap alerts remain intact. No qbit-alerts dependency is required; flags remain visible without a sink. The sink owns deduplication. End and expiry events remain in the break-glass activity list rather than representing new session anomalies.
+
+Thresholds are positive integers:
+
+| Config method | Default |
+| --- | ---: |
+| `withAnomalyDailyMedianMultiplier` | 3 |
+| `withAnomalyMinimumDailyReveals` | 10 |
+| `withAnomalyDistinctRecordsPerHour` | 20 |
+| `withAnomalyExactMatchesPerHour` | 50 |
+
+Medians use 30 scalar indexed counts on first qualifying use per user/day, cached for at most 2,048 users per instance and cleared at UTC day rollover. Today's and hourly counts read persisted history; distinct-record queries return at most the threshold plus one grouped rows. Counter evaluation and insertion serialize within an instance; other nodes become visible through persisted rows. This monitors activity rather than providing a distributed enforcement lock. Historical backfills after caching take effect next UTC day or after runtime restart. Existing deployments should apply the two new access-log indexes in `docs/ddl/secured-data-postgres.sql`.
+
+## Secured Data home
+
+The single Secured Data app owns one full-width HTML home widget, following qbit-webhooks' data/view/renderer pattern. It reads as the viewer with normal permissions and record security:
+
+- Six KPIs: reveals today, unexpired grants, active and unexpired break-glass sessions, anomaly flags and denied filters over seven days, and this runtime's access-log queue drops since startup. Denied filters include refused exact-match attempts.
+- Six full-width lists: recent reveals (10), top revealers and reasons (30-day backend aggregates, top 10), recent break-glass starts/ends/expiries (10), policy/classification changes (10), and seven-day anomaly flags (10).
+- Each list has a filtered access-log `View all` link without the widget's ten-row limit. Configure the host table route with `withTablePathPrefix("/app")`.
+
+Lists order newest first with id tie-breaking; rankings order by count descending then group alphabetically. Narrow screens use wrapping labelled card rows. Dates stay compact on one line, text is ellipsized with full tooltips, and colors inherit the host with `--qqq-grid-border` for borders. There are no inner scrollers. Empty lists explicitly say there is no activity.
+
+Navigation contains Classification, Policy, Access log, Break-glass sessions and Retention rules. Reveal grants remain a child list. A warning line appears under the KPIs for each active retention rule whose known backup retention exceeds its `age_days`. Successful policy/classification inserts, updates and deletes produce value-free change rows with actor, record id and action in the source transaction. No configuration values are copied into these rows.
+
+### Local screenshot harness
+
+`SecuredDataDemoServer` is a test-only memory-backed Next demo adapted from qbit-webhooks. It seeds synthetic activity for all six lists, including long reasons, sessions and anomaly flags. It uses a demo administrator and must only be run locally. After a test run, launch in PowerShell:
+
+```powershell
+[xml]$report = Get-Content target/surefire-reports/TEST-com.kingsrook.qbits.secureddata.SecuredDataHomeTest.xml
+$demoClasspath = ($report.testsuite.properties.property | Where-Object name -eq 'java.class.path').value
+java -cp $demoClasspath com.kingsrook.qbits.secureddata.SecuredDataDemoServer
+```
+
+Open `http://localhost:8098/app/secured_data`. Stop the demo before `clean` on Windows. Capture light and dark at 390, 768, 1024, 1440, 1920 and 3200 px under `target/screenshots/`. This session started the server, but screenshot capture was blocked by Chromium `spawn EPERM` in the sandbox and two connected-browser timeouts. The coordinator still needs to capture and inspect the twelve images through Next.
+
+## Retention and wipe
+
+Spec: SECURED-DATA sections 13 to 15. Retention rules live in the **Retention rules** table (permission `secured_data.retention`). Each rule names a host table, the fields to wipe, an age field, `age_days`, a batch size, an action and an audit treatment.
+
+Actions:
+
+- `NULL_WITH_MARKER`: set the fields to null (fields must be nullable) and record a wipe marker.
+- `OVERWRITE_TEXT`: replace with the rule's text (STRING/TEXT fields only; the text must fit the field).
+- `KEYED_HASH`: replace with an instance-key HMAC token (`hmac:v1:...`) that the host can still verify. Refused for low-entropy fields and for fields shorter than 200 characters.
+- `DELETE_RECORD`: delete the record, with markers for every field.
+- `ARCHIVE_THEN_WIPE`: write the field values as AES-GCM encrypted JSON through the host `ArchiveSinkInterface` (an adapter to object storage, ideally a WORM bucket), then null them. The wipe is refused if no sink is configured.
+
+Audit treatment: `SHREDDABLE` (default) gives each audited record-field its own data key (DEK), so deleting the key makes the audit tokens unverifiable (crypto-shredding). `CHANGED_ONLY` stores only `changed:v1` in audits and never creates a DEK.
+
+Mechanics:
+
+- Eligibility is evaluated in the database and returns record ids only; values are read only for `KEYED_HASH` and `ARCHIVE_THEN_WIPE`.
+- Each batch is one transaction in a rollback-capable backend: field updates, wipe markers, audit-key deletions, audit details, the access-log `WIPE` rows and the run row commit or roll back together. Cross-backend or non-transactional deployments are refused before any write.
+- Legal holds (per record, or per table with a blank record id) skip records; age and holds are re-checked inside the batch.
+- **Run wipe now** is a standard Review/Result process with counts only; the hidden `secured_data_wipe_daily` process runs daily from the host scheduler (`withSchedulerName`). Neither places a host value in a message, log, run row or marker.
+- DEKs are wrapped with AES-GCM under the KEK, with the table, field and record id as additional authenticated data. A wrong KEK or a wrong binding fails the unwrap. The wrapped-key table is hidden, locked, not exportable and audited at level NONE.
+
+### Backups are a residual risk (section 14.3)
+
+A wipe removes the value and its audit key from the live database only. Database backups taken before the wipe still contain the value and the wrapped DEK, and remain recoverable until they expire. Set `withBackupRetentionDays(...)`; when it exceeds a rule's `age_days` the rule and the app home warn that wiped values stay recoverable from backups. Unknown retention is reported as unknown, not as safe. Backups that must be purged earlier have to be handled outside this qbit.
+
+### Keys and environment
+
+| Variable | Purpose |
+|---|---|
+| `QQQ_AUDIT_HMAC_KEY` | Base64 32-byte instance key for `hmac:v1:` audit tokens and `KEYED_HASH`. Without it audits fall back to `changed:v1`. |
+| `QQQ_AUDIT_HMAC_KEY_ID` | Optional id embedded in tokens, default `env1`; change it when rotating the key. |
+| `QQQ_SECURED_DATA_KEK` | Base64 32-byte key-encryption key that wraps the per-record DEKs and archive objects. Required for `SHREDDABLE` and archive; a missing or invalid KEK fails closed. |
+
+Each is read from a JVM property or the environment and is never logged. Losing the KEK makes every existing DEK unrecoverable, so protect and back it up separately from the database.
+
+### Core hooks
+
+Audit-value protection, wipe audit flags and shredded audit events use the core #1182 APIs directly. Core tokenises ordinary audits and writes value-free wipe details. The section 15 canary and wipe-proof tests (`RetentionProofTest`) are mandatory in the normal build.
 
 ## Remaining phases
 
-RC.6 migration removes temporary types and reflection. Phase (c) adds Reveal and Start/End break-glass operations and expiry scheduling; this phase already reads active grants/sessions. Phase (e) adds the app home and broader anomaly rules. Retention, wipe and audit-value protection remain phases (f)/(g).
+Field-access and audit-token stand-ins and reflective bridges have been removed. The coordinator will replace the temporary snapshot pin with the first QQQ RC containing #1172 and #1182.
