fix(status): count real-time indexing failures

realTimeErrorCount was only ever written as 0, so the status screen, diagnostics and the status API always said there were no real-time errors. When the change listener records failed events it now adds their number to the table's count (after commit, serialized in the JVM, never failing the user's write). A successful basepull or full reindex resets it; the field's help text says so. Fixes #53 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

 ## [Unreleased]

+Requires QQQ 4.1.0-RC.6 or later (the spec-managed UI API extension contract).
+
+### Fixed
+- Real-time indexing failures now increase the table's error count by the number of failed events. Successful basepulls and full reindexes reset the count. Counter update failures are logged without failing the source write.

 ### Added
+- Supported host status API (`api.QuickSearchStatusService.get()`), immutable status values, and `QuickSearchApi` home navigation constants (issue #50/F10). Permission-checked, bounded diagnostics refreshes share a short per-runtime cache and reuse saved validation counts. New spec-managed `GET /qqq/v1/qbit/quick-search/status` (`getQuickSearchStatus`) with committed OpenAPI fragment and strict HTTP/contract tests. RC.6 requires the default `/qbit/quick-search` prefix; `/quick-search` is not permitted by core. Existing routes and wire shapes are unchanged.
 - Record developer panel: `QuickSearchDeveloperPanelProvider` (id `quickSearch`) adds a "Quick Search" panel to the developer view of every record of an indexed table (`/app/{table}/{id}/dev` in the Next UI), for users who may read Quick Search Index. It shows the table's index row (enabled, status, record count, last basepull and full reindex, searchable fields), the latest index run, the record's indexed document compared field by field with the database (Inspect Search Document's comparison; needs `debugPermissionRules`), the record's failed index events, the Inspect Search Document and Reindex in Search actions the user may run, and links to the admin app and the index row. An unreachable OpenSearch shows a warning in the panel. Registered by `QuickSearchDeveloperPanelsMetaDataProducer`.

 - **Data-driven configuration.** The searchable tables and fields are records: `quick_search_index` (the table registry, new columns `source` and `ownerEdited`) and the new `quick_search_index_field` (weight, role `DISPLAY`/`TITLE`/`SUBTITLE`/`BODY`/`KEYWORD`/`EXACT`, analyzer `PREFIX`/`WORD`/`ENGLISH`/`EXACT`, snippet and label flags). Indexing, search, the record-search provider and the diagnostics read the effective config from them (cached 30 s, dropped on change), so changes need no redeploy. Code (`@QuickSearchable`, `searchableTables`) only seeds them; rows an admin edited are never overwritten, and removals are remembered in the new `quick_search_config_tombstone`. Precedence and DDL: `docs/MIGRATION-1.1.md`, "Data-driven configuration".

 - `quick_search_validation_run` (with `enableDiagnosticTools`): `status` (`PASS`, `WARN`, `FAIL`), `triggerType` (`MANUAL`, `SCHEDULED`), `userName`, `tableNames`, `sampleSize`, `tablesChecked`, `failCount`, `warnCount`, `summary`, `reportHtml` (HTML), `reportJson` (text), `startTime`, `endTime`, `createDate`. Purged after `runHistoryRetentionDays`.
 - `quick_search_failed_event`: real-time events that could not be applied; `status` `PENDING` or `EXHAUSTED` after 10 attempts. Deletes made while a full reindex of all tables runs are also recorded here with status `AWAITING_REINDEX`: the reindex applies them to the new index after the alias swap (basepull does not replay them). While a table is `REBUILDING`, drift detection is suspended for it. Only one full reindex runs at a time: starting one while another is running fails. A full reindex shows it is running through its `FULL_REINDEX` run records, which stay `RUNNING` with `modifyDate` refreshed after every page. If it is killed mid-run (pod restart, OOM, deploy), recovery is automatic once its run records have shown no sign of life for `fullReindexStaleMinutes` (30 by default): the next basepull, or the next full reindex, marks those run records `FAILED`, returns the tables to `ACTIVE` with `lastBasepullTime` moved back to the run's start, and turns the `AWAITING_REINDEX` rows `PENDING` so basepull replays the deletes. No data is lost. A run that was only slow and is judged stopped notices before its alias swap and fails without swapping, or, after its swap, stops applying its captured deletes; basepull skips a replayed delete whose record exists again.

+Real-time error counts on Quick Search Index show failures since the last successful full reindex or basepull. Each failed event increases the count; deferred changes while indexing is paused do not. Counter updates are best effort and serialized across listeners in one JVM; concurrent application nodes can still race because QQQ has no arithmetic update API.
+
 ## Extending

 `IndexEventPublisher` lets a host replace the synchronous publisher with a queue. In 1.0 the SPI is experimental: `IndexEvent` carries the table, record id, action and the record snapshot, but no sequence number, so an asynchronous consumer must order INDEX and DELETE for the same record itself. `OpenSearchTransportCustomizer` customizes the HTTP transport.

+## Status API for hosts
+
+Requires QQQ **4.1.0-RC.6**. Hosts should use the supported API rather than reach into
+`QuickSearchRuntime`, `QuickSearchOpenSearchClient`, diagnostic renderers, or qbit tables:
+
+```java
+import com.kingsrook.qbits.quicksearch.api.QuickSearchStatus;
+import com.kingsrook.qbits.quicksearch.api.QuickSearchStatusService;
+
+// Runs in the host request's QContext, with the caller's QSession.
+QuickSearchStatus status = QuickSearchStatusService.get();
+String homeHref = status.homeHref();
+```
+
+UI clients use **`GET /qqq/v1/qbit/quick-search/status`**, operationId
+`getQuickSearchStatus`, extension `quick-search` version `1.0.0`. The endpoint returns
+that same immutable value as JSON; it requires the Quick Search app's configured
+`adminPermissionRules` (default `quick_search_admin.hasAccess`). Permission is checked
+before every read, including cache hits. No additional source-table permissions are
+required: like index validation, this is an administrator's aggregate view of the index.
+The committed contract is [quick-search.yaml](src/main/resources/openapi/qqq-v1/quick-search.yaml).
+
+The default core namespace is intentional: RC.6 permits `/qbit/quick-search` but rejects
+`/quick-search`, which is not an established legacy prefix. There were no existing
+Quick Search UI API routes to preserve. Core source is unchanged.
+
+- `state`: `OK`, `DEGRADED` (including paused indexing, backlog, incomplete diagnostics
+  or a refresh timeout), `DOWN` (unavailable health or red health), or `DISABLED`
+  (qbit absent or every persisted index disabled). Pausing indexing does not disable search.
+- `clusterReachable`, `clusterHealth`, `nodes`, `activeShards`, `unassignedShards` come
+  from the existing diagnostics health operation. Null means unknown/not probed.
+- `indexes` contains up to 100 persisted index rows. `documentCount` and `sourceCount`
+  come from the latest saved `IndexValidator` report, with `countsCheckedAt`. Without
+  matching validation, only the last indexing run's document count is available and
+  its observation time is unknown. These are **saved counts, not live counts**. A
+  missing source count must not be displayed as zero or “in sync.”
+- `pending` includes `PENDING` and `AWAITING_REINDEX` failed events; `exhausted` counts
+  failed events that gave up. At most 1000 backlog rows are read; `backlogTruncated`
+  makes both counts lower bounds. `tablesTruncated` indicates incomplete index rows.
+  These counters do not measure an external publisher's queue.
+- `lastSuccessfulSync` is the newest successful indexing watermark among the included
+  tables (basepull is start-anchored), not proof that all tables are current.
+  `lastError` is the newest available indexing/runtime search error or snapshot failure.
+- `checkedAt` is snapshot completion time. A per-runtime five-second cache bounds
+  polling cost; each refresh uses `DiagnosticsRateLimiter`'s per-user `STATUS` key.
+  Rate-limit refusal uses the existing diagnostics error (HTTP 400). A refresh waits
+  at most two seconds and retains at most one in-flight worker, even if a backend is
+  stuck. Runtime shutdown stops the worker. No source counts, record samples, full
+  validation, or per-table OpenSearch calls run on this polling path.
+
+Link to `status.homeHref()` instead of copying the Quick Search home. It includes the
+configured metadata prefix. `QuickSearchApi.APP_NAME` (`quickSearchAdmin`) and
+`QuickSearchApi.HOME_HREF` (`/app/quickSearchAdmin`) are available for default-name
+navigation. Keep detailed runs, failed events, validation and operator tools in the
+qbit's own home. [kof22 migration mapping](docs/STATUS-API-HOST-MIGRATION.md).

+
+## Real-time error counter fix (2026-10-14)
+
+- Failed-event recording now increments the table's `realTimeErrorCount` after commit, using QQQ reads and system writes. Null counts start at zero; update failures are logged and cannot fail the source write or prevent replay.
+- QQQ has no arithmetic update API. The read-modify-write fallback is serialized across listeners in this JVM; separate application nodes can still race.
+- Successful basepull and full-reindex status updates reset the count, including the single-table reindex path. Investigation found the previous zero assignments only initialized new rows. Field help, README and Unreleased changelog now describe the reset window.
+- Regression coverage includes event counts, concurrent listeners, counter-update failure, after-commit timing, basepull reset and both full-reindex reset paths.
+- Final gate: `./mvnw.cmd -o -B verify` passed against released QQQ 4.1.0-RC.6: 476 unit tests, zero failures/errors; 41 integration tests skipped because Docker is unavailable; architecture guardrails and JaCoCo coverage gates passed. No dependency changes or offline artifact gaps. Checkstyle, PMD and SpotBugs are not configured in this Maven build.
+- No commit, push or branch creation. Second-brain save is blocked by the vault being outside writable roots; this section retains the durable handoff for later vault synchronization.
+
+## Status API worktree (2026-10-13, issue #50 / F10)
+
+- Implemented `api.QuickSearchStatusService.get()`, immutable status values, default app/home constants and a spec-managed status endpoint. Admin permission is checked on every call; saved validation counts avoid source scans. Five-second per-runtime cache, two-second wait, one in-flight worker, existing diagnostics rate limiter, bounded table/backlog reads.
+- Endpoint uses core's permitted `/qqq/v1/qbit/quick-search/status` namespace (`getQuickSearchStatus`). Requested `/quick-search` is rejected by RC.6's established-prefix allowlist. Core and host clones are read-only; no edits there. No previous Quick Search HTTP operations or Next UI callers found.
+- POM targets released-coordinate `4.1.0-RC.6`; local verification uses only `-Dqqq.snapshot.version=4.1.0-ARCHRC6-SNAPSHOT`.
+- Host file/line replacement mapping: `docs/STATUS-API-HOST-MIGRATION.md`. Contract: `src/main/resources/openapi/qqq-v1/quick-search.yaml`.
+- Verification: 468 unit tests (including strict HTTP, contract, bounds, cache isolation, permissions and timeout recovery); JaCoCo passes. All 41 Docker integration tests skip because Docker is unavailable. Final command: `./mvnw.cmd -B verify -Dqqq.snapshot.version=4.1.0-ARCHRC6-SNAPSHOT`.
+- Standalone repository Checkstyle is not green: HEAD has 471 main-source violations; this tree has 438, with zero newly introduced violations. New production files and both new test files pass their style checks. Existing header/import/style cleanup is outside the status API change.
+- No commit, push, merge or deployment authorized. Second-brain vault is outside writable roots; durable notes are retained here for later vault synchronization.

+# Quick Search host migration (kof22 #164)
+
+Issue #50 / architecture finding F10. Paths below are under
+`Website-Backend/src/main/java/com/kof22/website/metadata/adminhome/`;
+line numbers refer to the local clone inspected on 2026-10-13. No host files were changed.
+
+| Existing host code | Replacement |
+| --- | --- |
+| `LiveAdminHomeProbes.java:340` `searchConfigured()` | Use `QuickSearchApi.APP_NAME` for the default-name app lookup; for an authorized snapshot use `QuickSearchStatusService.get()` and its state/homeHref. `DISABLED` also includes all indexes disabled, so it is not exactly “qbit absent.” |
+| `LiveAdminHomeProbes.java:351` `searchCluster()` | One `QuickSearchStatusService.get()`; map `clusterReachable`, `clusterHealth`, `nodes`, `activeShards`, `unassignedShards`. Remove direct cluster HTTP/auth/CA handling. |
+| `LiveAdminHomeProbes.java:386` `searchDocumentCounts(...)` | Reuse the same snapshot's `indexes()` and each row's `tableName()` / `documentCount()` / `sourceCount()` / `countsCheckedAt()`. Remove `QuickSearchOpenSearchClient` access and relabel counts as saved diagnostics, not live. Preserve null as unknown. |
+| `QuickSearchHomeWidgets.java:118` `widgets()` | Stop adding the host's duplicate Quick Search home widgets. Link to `status.homeHref()` (or default `QuickSearchApi.HOME_HREF`). Keep the qbit-provided home/diagnostics widget. |
+| `QuickSearchHomeWidgets.java:133` `indexFacts()`, `:160` `summary()` and `:196` `syncTile()` | For a compact host overview, use the same `QuickSearchStatusService.get()` value: `state`, `indexes`, `pending`, `exhausted`, `lastSuccessfulSync`, `lastError`. Remove SQL aggregates and live source counts; use saved count timestamps and truncation flags. |
+| `QuickSearchHomeWidgets.java:267` `runs()`, `:315` `failedEvents()` | Replace duplicate detailed views with the home link; drill down using the qbit's own Index Run / Failed Event tables from that home. The summary API intentionally does not export detailed histories. |
+| `AdminOperationsWidgets.java:209` `quickSearch()` | Render `status.indexes()` for the compact admin overview, and use `status.homeHref()` for its footer link. Remove qbit-table SQL and source-table counts. |
+| `AdminOperationsWidgets.java:343` `searchFooter()` | Use `clusterHealth`, `pending`, `exhausted`, `lastSuccessfulSync`, `lastError`, and `checkedAt` from the same snapshot. Detailed recent-run information belongs in the qbit home. |
+
+Call with the existing request's `QContext`/`QSession`; do not elevate a host user's
+session to bypass `adminPermissionRules`. Cache hits still check permission.
+
+## UI contract
+
+| Method | Path | operationId |
+| --- | --- | --- |
+| GET | `/qqq/v1/qbit/quick-search/status` | `getQuickSearchStatus` |
+
+Extension: `quick-search`, version `1.0.0`; core dependency: `4.1.0-RC.6`.
+The requested `/quick-search` prefix cannot validate on the supplied RC.6 baseline:
+`MiddlewareSpecExtensionsMetaData.ESTABLISHED_PREFIXES` only admits esb, alerts,
+assistant, and sql-workbench. We use the default namespace without modifying core.
+
+Wire changes against develop: one additive endpoint and its schemas; no existing
+method, path, request, or response changed. Next UI `src/` contains no calls to a
+Quick Search-specific endpoint today; its core `/qqq/v1/search` integration is unchanged.
+Vendor `src/main/resources/openapi/qqq-v1/quick-search.yaml` for clients.
+
+Regenerate the fragment with:
+
+```powershell
+./mvnw.cmd -B test -Dtest=QuickSearchApiContractTest -Dquicksearch.openapi.update=true -Dqqq.snapshot.version=4.1.0-ARCHRC6-SNAPSHOT
+```
+
+The local verification override is never the committed dependency version.
+
+## Verification and limits
+
+`./mvnw.cmd -B verify -Dqqq.snapshot.version=4.1.0-ARCHRC6-SNAPSHOT` passes
+468 unit tests and JaCoCo, including strict HTTP server startup, permission checks,
+OpenAPI contract consistency, cached/disabled/degraded/down states, timeout recovery,
+bounded backlog/table lists and prefixed QInstance isolation. All 41 Docker integration
+tests skip locally because Docker is unavailable.
+
+The separate Checkstyle check is **not green**: the existing checked-in rules report
+471 main-source violations at HEAD and 438 in this worktree, with zero new violations.
+New source files and the two new tests pass those rules. No repository-wide header
+rewrite or unrelated style cleanup was included.

james.maesandClaude Opus 5.5	1a4a29fa2b	fix(status): count real-time indexing failures realTimeErrorCount was only ever written as 0, so the status screen, diagnostics and the status API always said there were no real-time errors. When the change listener records failed events it now adds their number to the table's count (after commit, serialized in the JVM, never failing the user's write). A successful basepull or full reindex resets it; the field's help text says so. Fixes #53 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-14 10:42:35 -05:00

james.maesandClaude Opus 5.5	a099a1d1b5	feat(api): QuickSearchStatus API and spec'd GET /qbit/quick-search/status Hosts no longer need QuickSearchOpenSearchClient or a copy of this qbit's diagnostics. The new public api package holds: - QuickSearchStatus, an immutable snapshot: overall state, cluster reachability, per-table index counts, backlog, last sync, last error and checkedAt; - QuickSearchStatusService.get(), bounded and cached for five seconds, built on the existing diagnostics; - QuickSearchApi, with the app name and home href, so hosts link to the Quick Search home instead of duplicating it. The same data is served as UI API extension operation GET /qqq/v1/qbit/quick-search/status (getQuickSearchStatus), gated by the admin permission. The fragment is committed and checked by a contract test. The core baseline becomes 4.1.0-RC.6. Closes #50 (architecture review QRun-IO/qqq#1150, finding F10).
