 ### Added
+- Host-neutral in-app help bundle `help/qbit-sql-workbench.yaml`, registered with QQQ help bundles, with live references and coverage checks for workbench metadata and generated table actions. Replaces the earlier minimal bundle while retaining inline app/table help for hosts without help storage. Requires QQQ `4.1.0-RC.7`.
+- Table help: the SQL Workbench app and every `sql_workbench_*` table carry help saying what the table is for and how its rows get created (`help/qbit-sql-workbench.yaml`, QQQ help-bundle format, applied by `SqlWorkbenchHelp`; host help is never overridden). `SqlWorkbenchTablesGuardrailTest` fails when a table is unused by runtime code, unexplained, or has no such help. All six tables are user content or logs and start empty by design; nothing is seeded.
+- `auditRetentionDays` config (default null: keep forever, no change for existing hosts): when set, execution audit rows older than that many days are deleted, in the background in bounded batches, at most once an hour per process (first pass 5 minutes after start), triggered as a run is audited; rows still RUNNING are kept. DESIGN.md already described this setting; it did not exist before.
+- OpenAPI coverage for all 21 SQL Workbench UI API operations, including streaming CSV/JSON/XLSX export. The `sql-workbench` extension preserves `/qqq/v1/sql-workbench`, existing request/response shapes, permission and ownership checks, exact decimal parameters, execution limits and audit. The generated fragment is in `src/main/resources/openapi/qqq-v1/sql-workbench.yaml`; strict-server security tests and a fragment contract test guard it.
 - **App home dashboard.** The `sqlWorkbench` app's home is now an information dashboard of real data, read in the viewer's session (permissions and record locks apply): summary tiles and links, runs per day, recent notebooks, recent runs, slowest and failed queries, most-used notebooks, shared notebooks, committed writes, and (workbench admins only) activity by user. Each widget has an honest empty state.
 - **Runner.** The notebook editor (`SQL_WORKBENCH` widget) moves to its own nav entry: the `sqlWorkbenchRunner` child app, labeled Runner. Open a notebook with `/app/sqlWorkbenchRunner?notebook=<id>`.
 - On a notebook's record view: an Open in Runner widget, and a Runs child list (its executions the viewer may see) through the new join `sql_workbench_notebook_join_sql_workbench_execution`.

 - **Record developer panel** "SQL Workbench" (`SqlWorkbenchDeveloperPanelProvider`, registered by `SqlWorkbenchDeveloperPanelsMetaDataProducer`): read-only `SELECT`s for the record and its table in the backend's own names, backend details, and links that open them in the Runner as a new cell (`/app/sqlWorkbenchRunner?sql=&backend=`, never run). Requires QQQ 4.1.0-RC.4 (the developer panel contract) and a Next UI with the Runner `?sql=` support.

 ### Changed
+- UI API extension sql-workbench 1.1.0 (requires QQQ 4.1.0-RC.15, UI API 1.6.0): operationIds, standard error responses with BasicErrorResponseV1, extension tags, and deprecated SqlWorkbenchErrorV1 retained for compatibility. Existing operationIds, HTTP statuses and success payloads are preserved.
+- Require QQQ `4.1.0-RC.6` for the UI API extension contract. Replace the raw Javalin route provider with endpoint specs registered by the qbit producer. `registerRoutes=false` still disables HTTP registration. No existing operation wire changes.
 - **The nav lists only the main tables**: Notebooks and the execution audit, after the Runner. Cells, versions, pinned results and shares are child lists on a notebook (still standard tables, reachable by URL and API). The app's widget list is now the dashboard, not the `SQL_WORKBENCH` widget; links to `/app/sqlWorkbench` that expected the editor should point at `/app/sqlWorkbenchRunner`.
 - The notebook record's header shows the description.
 - **Names follow the owner rule: lowercase snake_case, prefixed with the qbit's name (metadata only, no DDL).** Tables `sql_workbench_notebook`, `sql_workbench_cell`, `sql_workbench_notebook_version`, `sql_workbench_result_snapshot`, `sql_workbench_notebook_share`, `sql_workbench_execution` (they now equal their backend table names); possible-value source `sql_workbench_share_audience_type`; permissions `sql_workbench.*`, `sql_workbench_admin.hasAccess` and `<table>.read` etc.; security key types `sql_workbench_user` (all-access `sql_workbench_all_access`) and `sql_workbench_audience`; joins `sql_workbench_notebook_join_sql_workbench_*`.
 - `tableNamePrefix` (and the QBit namespace) is normalized to lowercase snake_case and joined with one `_`.

-### Deprecated
- `LEGACY_TABLE_NAME` on each entity, `ShareAudienceType.LEGACY_NAME` and `SqlWorkbenchQBitConfig.LEGACY_*` hold the pre-RC.3 names, for migrating stored references only.
+### Fixed
+- **Pinning a result works with QQQ core permission enforcement on.** `getUserPermissionNames()` now includes `sql_workbench_result_snapshot.insert`: pinning is a top-level insert, which core enforcement checks, so hosts no longer need to grant it by hand. Record locks still limit snapshots to the user's own notebooks.

+### Deprecated
+- `LEGACY_TABLE_NAME` on each entity, `ShareAudienceType.LEGACY_NAME` and `SqlWorkbenchQBitConfig.LEGACY_*` hold the pre-RC.4 names, for migrating stored references only.

 The workbench's data becomes standard QQQ tables, secured by QQQ's own mechanisms instead of being hidden ([#3](https://github.com/QRun-IO/qbit-sql-workbench/issues/3)). Requires QQQ `4.1.0-RC.4` or later ([qqq#1073](https://github.com/QRun-IO/qqq/issues/1073)).

 To move the app under another app (for example an Admin app), re-parent `SqlWorkbenchQBitProducer.APP_NAME` after producing; the Runner moves with it. Open a notebook in the Runner with `/app/sqlWorkbenchRunner?notebook=<id>`.

+## In-app help
+
+The producer registers [help/qbit-sql-workbench.yaml](src/main/resources/help/qbit-sql-workbench.yaml), a `QBIT` bundle with summaries, Markdown help and live metadata references. Hosts with `helpContent` load help and call `HelpBundles.syncOnStartup(qInstance)` after defining metadata. Registration itself needs no help table; app/table inline help remains available without one.
+
+To override wording, register your own resource with `HelpBundles.register(qInstance, "help/my-host.yaml")`, set `layer: HOST`, and use the same entry `key` and `role` (default `ALL_SCREENS`). HOST text takes precedence over QBIT text; user-edited help is preserved by sync. Keep the bundle's literal version aligned with the POM version when releasing.
+
+`SqlWorkbenchHelpBundleTest` uses `HelpBundleAssertions` to check ownership coverage, keys, summary lengths and live references, including generated table actions. Run it with `./mvnw -q test -Dtest=SqlWorkbenchHelpBundleTest`; it also verifies registration without a help table.
+
 ## App home

 The app's home page is a dashboard of real data, read through QQQ's core actions in the viewer's session. Permissions and record locks therefore decide what each widget counts: a user sees their own runs and the notebooks they can open, and a workbench admin sees everyone's. A widget whose table the user may not read says so rather than showing zeros. Every widget is full width and has an empty state.

+## Starter defaults and retention
+
+All six tables are user content (notebooks, cells, shares, pinned snapshots) or logs (versions, the execution audit), so none is seeded: they start empty, and each table's help (`help/qbit-sql-workbench.yaml`, shown on the table screen) says how its rows get created. No host include or action is needed.

+
 ## Storage upgrade from 1.0.0-RC.1

 RC.2 adds `sql_workbench_notebook_share`. The DDL creates it and backfills an `all` share (the shared library) for every notebook whose `visibility` is `SHARED`; it is additive and idempotent, and owners (`owner_user_id`) are unchanged. Run it before deploying RC.2: without the share rows, published notebooks are visible only to their owners.

-The owner naming rule now applies to every QRun-IO qbit: table names are lowercase snake_case, prefixed with the qbit's name. In 1.0.0-RC.3 the SQL Workbench's QQQ names change to match. **The database does not change**: the physical tables were already `sql_workbench_*` (`docs/ddl/postgres.sql`), so no DDL runs.

+# SQL Workbench UI API contract
+
+All 21 operations are registered by `SqlWorkbenchQBitProducer` through
+`SqlWorkbenchEndpoints` as one `MiddlewareSpecExtension` named `sql-workbench`,
+version `1.0.0`, with the established `/sql-workbench` prefix. Full URLs remain
+`/qqq/v1/sql-workbench/...`. QQQ `4.1.0-RC.6` is the minimum core version.
+`registerRoutes=false` disables extension registration; middleware remains optional.
+
+The producer registers no raw routes. Twenty JSON operations extend
+`AbstractJsonEndpointSpec` through `SqlWorkbenchJsonSpec`; `ExportResultSpec`
+extends `AbstractEndpointSpec` directly and streams CSV, JSON or XLSX with the
+existing attachment filename and `Cache-Control: no-store` headers.
+
+The checked-in fragment is
+[`src/main/resources/openapi/qqq-v1/sql-workbench.yaml`](../src/main/resources/openapi/qqq-v1/sql-workbench.yaml).
+It is also included in a host's `/qqq/v1/openapi.yaml` and `.json`, and the
+extension appears in `/qqq/v1/version`. All component names begin with
+`SqlWorkbench`. Schemas explicitly describe the existing map payloads rather
+than changing their serialization. SQL results include nullable scalar values,
+binary previews and nested arrays; execute responses vary by execution status.
+
+## Compatibility and security
+
+No existing operation paths, methods, request or response shapes, status codes,
+or export headers change. Next UI can vendor the fragment without adapting its
+existing calls. New metadata consists of the extension/version advertisement,
+OpenAPI schemas and stable operation identifiers.
+
+Core authenticates the caller before each spec runs and clears `QContext` after
+the request. Workbench access is checked before parsing bodies, path integers or
+export formats. JSON object parsing retains `BigDecimal` precision, JSON-only
+content-type checks, empty/null-body behavior, and existing error messages.
+Duplicate execution UUIDs still return 409. SQL failures remain HTTP 200 with a
+`FAILED`, `TIMED_OUT` or `CANCELLED` execution status.
+
+Specs call the same `SqlWorkbenchApi`, notebook service and execution engine.
+Write/EXPLAIN ANALYZE gates, sharing permissions, caller record locks, notebook
+ownership, cached-result ownership, cancellation ownership, per-user concurrency
+limits, audit-before-SQL and deferred audit updates remain in place. Client IPs
+continue into execution audits. No request bodies or result data are logged by
+the transport.
+
+## Operations
+
+| Method | Path (after `/qqq/v1/sql-workbench`) | operationId |
+|---|---|---|
+| GET | `/capabilities` | `sqlWorkbenchGetCapabilities` |
+| POST | `/execute` | `sqlWorkbenchExecute` |

+
+## Verification and regeneration
+
+`SqlWorkbenchApiContractTest` regenerates the fragment in memory and checks it
+against the checked-in file using core's deterministic `UiApiContract` tooling.
+It also checks the namespace, secured specs, prefix, media types and 21 unique
+operation IDs. Intentional contract changes can regenerate the file with:
+
+```sh
+./mvnw -B test -Dtest=SqlWorkbenchApiContractTest -DsqlWorkbench.openapi.update=true
+```
+
+Before RC.6 is released, local verification uses the separately installed core:
+
+```sh
+./mvnw -B verify -Dqqq.snapshot.version=4.1.0-ARCHRC6-SNAPSHOT
+```
+
+The POM must continue to name `4.1.0-RC.6`; the local override is never a release
+dependency. On PowerShell, quote each `-D...` argument and use `mvnw.cmd`.
+
+`SqlWorkbenchEndpointSpecTest` runs real HTTP through
+`QApplicationJavalinServer.withStrictUiApiRoutes(true)`. It preserves the former
+route-provider tests and adds 401/403 coverage for every operation, mutation
+denials, execution limits, audited rejection, exact decimals, SQL failures and
+all three exports. Engine tests continue to verify audit and transaction safety.

+  summary: 'A SQL notebook for your databases: write queries, run them read-only, and review every run afterwards.'
+  content: |
+    The home page is a dashboard of your notebooks and recent runs (admins see everyone's). Use **{{label:sqlWorkbenchRunner}}** to write and run SQL, **{{label:sql_workbench_notebook}}** to manage saved notebooks, and **{{label:sql_workbench_execution}}** to see who ran what.
+
+    **Safe by default.** Runs are read-only and one statement at a time. Writing to the database needs write mode enabled by your administrator, the separate write permission and two steps: a dry run that is rolled back, then a confirmation.
+
+    **Who sees what.** You see your own notebooks, notebooks shared with you, and your own runs. Administrators see everything.
+
+    Raw SQL bypasses normal application record rules, history and search updates. Use application processes for business changes. Every run is recorded in the execution audit.
+- key: app:sqlWorkbenchRunner;slot:help

+    Open a notebook from **{{label:sql_workbench_notebook}}** (the **Open in Runner** link) or start a new one here.
+
+    - A notebook is a list of cells. A SQL cell holds a query, a Markdown cell holds notes.
+    - Each SQL cell runs against one database; read-only is the default.
+    - Named parameters written as :name in the SQL are always bound as values, never pasted into the text.
+    - Saving creates a new version. Results can be pinned as snapshots and exported.
+
+    Only one statement runs per cell in read-only mode, and your administrator sets the limit on simultaneous runs.
+- key: table:sql_workbench_notebook;slot:help
+  summary: 'A saved SQL notebook: its title, default database, parameters and cells, owned by one person.'
+  content: |
+    **How rows get created:** You create a notebook in the Runner or with New here. It starts with your own content.
+
+    Notebooks are personal until the owner shares them. You can read your own notebooks and ones shared with you; only the owner (or an administrator) can edit or delete one.
+
+    The record view lists the notebook's **Cells**, **Shares**, **Snapshots (pinned results)**, **Versions** and **Runs**, and has an **Open in Runner** link. Actions: **{{label:sqlWorkbenchShareNotebook}}** and **{{label:sqlWorkbenchDuplicateNotebook}}**.
+
+    Creating a notebook here makes you the owner and saves version 1. Deleting a notebook also deletes its cells, versions, pinned results and shares. Past runs stay in **{{label:sql_workbench_execution}}**.

+  content: |
+    Reference a parameter in SQL as :name. Values are always bound safely, never pasted into the statement. The Runner has a parameters panel that edits this for you; if you type it by hand it must be a valid JSON list or the save is refused.
+- key: table:sql_workbench_notebook;field:ownerUserId
+  summary: The sign-in id of the owner, set automatically from whoever created the notebook.
+  content: |
+    Only an administrator can change it, which transfers the notebook to someone else (the owner name then follows the new id).

+    **How rows get created:** You use Share Notebook or add a share from the notebook's Shares list.
+
+    A share never lets anyone edit the notebook; it only lets them open and run it. Add one from a notebook's **Shares** list or with the **{{label:sqlWorkbenchShareNotebook}}** action. You need the share permission, and only the notebook's owner or an administrator can add or remove shares.

+- key: table:sql_workbench_cell;slot:help
+  summary: 'One block of a notebook: a SQL query or a Markdown note.'
+  content: |
+    **How rows get created:** You add SQL or Markdown cells to a notebook in the Runner or from its Cells list.
+
+    Cells are normally edited in the Runner, but you can add, edit, reorder and delete them here. A notebook can hold at most 200 cells, and your administrator sets the SQL length limit.
+
+    Every add, edit or delete saves a new notebook version, just like saving in the Runner. A new cell is added at the end with a generated key. Only the notebook's owner or an administrator can change cells.
+- key: table:sql_workbench_cell;section:identity

+- key: table:sql_workbench_notebook_version;slot:help
+  summary: 'A read-only history entry: the full content of a notebook as it was at one save.'
+  content: |
+    **How rows get created:** The workbench saves a version when you create or change a notebook or its cells.
+
+    A new version is written each time the notebook is saved, a cell is added, edited or removed, or an older version is restored. It holds the title, description, parameters and all cells. You cannot edit or delete versions yourself. Older versions are pruned according to your administrator's retention setting.
+
+    To go back, run **{{label:sqlWorkbenchRestoreNotebookVersion}}** on the version you want. That saves it as a new, latest version, while retained versions remain available.
+- key: table:sql_workbench_notebook_version;section:identity

+- key: table:sql_workbench_result_snapshot;slot:help
+  summary: A query result pinned from a notebook so you can look at it later without re-running the SQL.
+  content: |
+    **How rows get created:** You run a query in the Runner and pin its result to your notebook.
+
+    Pin a result from the Runner after running a cell. A snapshot keeps the column list, rows up to the configured snapshot limit, the SQL that produced it and the database it came from. It contains real query data, so it is visible only to the notebook's readers and administrators.
+
+    You cannot add snapshots here, and the only thing you can edit is the **{{label:sql_workbench_result_snapshot.label}}**. Delete a snapshot you no longer need.
+- key: table:sql_workbench_result_snapshot;section:identity
+  summary: Which notebook and cell the result came from and its label.
+- key: table:sql_workbench_result_snapshot;section:result
+  summary: The pinned rows, the SQL and database that produced them, and whether the result was cut short.

+  summary: The sign-in id of the person who pinned the result.
+- key: table:sql_workbench_execution;slot:help
+  summary: 'The audit log of SQL runs: who ran what, where, how long it took and how it ended.'
+  content: |
+    **How rows get created:** The workbench records runs before executing SQL, including rejected SQL attempts.
+
+    Every run is recorded before the SQL starts, and attempts that were refused are logged too, so this is the place to answer "who changed or read this?". Rows are added and updated by the workbench only; you cannot edit or delete them. Your administrator can configure automatic removal of older completed runs.
+
+    You see your own runs; administrators see everyone's. The log keeps the SQL text and parameter values, but never the result rows.
+
+    Use the filters on **{{label:sql_workbench_execution.status}}**, **{{label:sql_workbench_execution.mode}}**, **User** and **{{label:sql_workbench_execution.startTime}}** to narrow it down, or open a run from a notebook's **Runs** list.

james.maesandClaude Opus 5.5	6da4fb400d	test(ddl): guardrail that every table reference has a foreign key PostgresIntegrationTest applies docs/ddl/postgres.sql on PostgreSQL and checks that every join and every table possible-value reference between the workbench's tables has a foreign key, or an exemption with a reason. The only exemption is sql_workbench_execution.notebook_id, by design: the execution audit is append-only and outlives its notebook. CASCADE would delete audit rows, RESTRICT would block deleting any notebook that ever ran (NotebookTableCustomizer deletes cells, versions, pinned results and shares, not the audit), SET NULL would rewrite audit rows, and the engine records the client's notebook id even when that notebook was deleted meanwhile, so the audit insert must never fail on it. The existing notebook foreign keys stay NO ACTION: NotebookTableCustomizer deletes the children through QQQ (audits, locks) before the notebook.

james.maesandClaude Opus 5.5	7c2d0610a5	fix(ddl): index result_snapshot.notebook_id and execution.notebook_id The foreign key sql_workbench_result_snapshot.notebook_id had no index. NotebookService lists a notebook's snapshots by it, the notebook delete cascade and the child record lock use it, and the notebook page's Runs list joins executions on notebook_id. The reference DDL and the H2 test schema add both indexes. The Postgres integration test now fails if any sql_workbench_ foreign-key column lacks a leading index.

JSON operations use AbstractJsonEndpointSpec; the result export stream extends AbstractEndpointSpec. Paths, methods and payloads are unchanged, and so are the permission checks, read-only gates, limits and audit. The generated fragment is committed at openapi/qqq-v1/sql-workbench.yaml and checked by a contract test. The server tests run in strict raw-route mode. The core baseline becomes 4.1.0-RC.6, the first RC with the extension point (QRun-IO/qqq#1128). Closes #20 (architecture review QRun-IO/qqq#1150, finding F2).

With QQQ core permission enforcement on, that insert is checked against the session's permissions, and getUserPermissionNames() granted only read/edit/delete on snapshots, so every user's pin was denied and hosts had to grant the insert by hand. Record locks still limit snapshots to the user's own notebooks. New test: with enforcement on, the user permission set covers create, update, run, pin, unpin and delete.
