+## [1.0.0-RC.3] - Unreleased
+
+### Added
+- **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`.
+- `SqlWorkbenchIntegrations`: opt-in ESB (`esbTableNames`) and Quick Search (`quickSearchTables`) hooks for the main tables, with no dependency on either module.
+- **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
+- **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.
+
+### Upgrade from RC.2
+- Follow [UPGRADE.md](UPGRADE.md): grant the renamed permissions and rename stored table names (audit, saved views and reports). No DDL.
+
+## [1.0.0-RC.2] - Unreleased
+
+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)).
+
+### Added
+- `sqlWorkbenchNotebookShare`: share a notebook, read-only, with a user, a group, or everyone (`ALL`, the shared library). Publishing in the notebook UI now writes an `ALL` share; a notebook's `visibility` follows its shares.
+- Record security locks on every table, enforced by QQQ's core actions (table UI, `/qqq/v1` table API, export, PVS lookups, processes, the workbench endpoints): owners see and change their notebooks and children, share audiences read them, users read their own execution audit, admins (`sqlWorkbenchAdmin.hasAccess`) hold the all-access key. Security key types `sqlWorkbenchUser` and `sqlWorkbenchAudience`; `SqlWorkbenchSecurity.applyToSession(qInstance, session, groups)` puts the keys in a session.
+- Per-table `read` / `insert` / `edit` / `delete` permissions, listed per role by `SqlWorkbenchQBitConfig.getUserPermissionNames()`, `getSharePermissionNames()` and `getAdminPermissionNames()`.
+- All six tables are children of the `sqlWorkbench` app, with record-view sections, child-list widgets (cells, shares, pinned results, versions) and SQL / JSON code-editor adornments.
+- Record actions (processes on tables, not in the nav): Share Notebook, Duplicate Notebook, Restore Version.
+- Table customizers that keep the notebook invariants for every entry point: ownership from the session, cell validation and ordering, one version per change, share keys and visibility, append-only versions and audit (also for admins), pinned results only from pinning, cascading notebook deletes.
+- Record-level QQQ audits for notebooks, cells, pinned results and shares.
+
+### Changed
+- `NotebookService` and the history endpoint run as the caller's session through the standard table actions (no system-user bypass); the explicit owner / share checks stay as defense in depth.
+- The tables' permission rules are per-table permissions instead of `sqlWorkbenchAdmin.hasAccess`. Hosts must grant the new lists and call `applyToSession`.
+- Built against QQQ `4.1.0-RC.4`.
+
+### Upgrade from RC.1
+- Run the share-table DDL from `docs/ddl/postgres.sql`: it creates `sql_workbench_notebook_share` and backfills an `all` share for each `SHARED` notebook (additive, idempotent; owners unchanged).
+- Grant the permission lists and call `SqlWorkbenchSecurity.applyToSession` in the authentication customizer.

+You write SQL and markdown in notebook cells, run them against any RDBMS backend of the instance (Postgres, MySQL, SQLite, H2), and see typed, paged, exportable results, quick charts, and visual EXPLAIN plans. The notebook UI (the **Runner**) lives in the [Next UI](https://github.com/QRun-IO/qqq-frontend-next) as a `SQL_WORKBENCH` widget on its own page in the app's nav. The app's home page is an information dashboard over the notebooks and the execution audit.
 
 - **Read-only by default.** A default session runs one statement inside a database `READ ONLY` transaction, and a statement classifier refuses anything that isn't a read.
 - **Gated write mode.** Writes need a separate permission and two steps. First a dry run executes in a transaction that is rolled back, so you see the affected-row counts. You then confirm with a single-use token bound to that exact SQL. A row guard, a hard cap, a drift check, and statement timeouts apply.

+
+## ESB and Quick Search
+
+`SqlWorkbenchIntegrations` is an opt-in hook: it names what to wire, and the host wires it with its own modules (the qbit depends on neither).
+
+- **ESB:** `esbTableNames(config)` lists the main tables. Publish their insert, update and delete events the usual way, for example `EsbTableMetaData.ofOrWithNew(qInstance.getTable(name)).withPublication(new EsbTablePublication().withDestinationName(...).withEvents(...))`. Execution rows are inserted when a run starts and updated when it ends.
+- **Quick Search:** `quickSearchTables(config)` lists the main tables with weighted fields, the basepull timestamp field and a hit label. Notebooks: title, description, owner, default backend. Executions: SQL text, execution UUID, user, error, backend. Map each to a `SearchableTableConfig` (with `new SearchableFieldConfig(name).withWeight(w)`). Hits are re-read through the tables' record locks, so a user finds only what they could open. The Quick Search record developer panel then covers these tables too.
+
+What leaves the database: a notebook event or search document carries the notebook row. An execution event carries the audit row, which includes the SQL text and parameter values, and its search document includes the SQL text. Results are never stored, so they are never published or indexed. Decide whether that suits your broker and search cluster before you opt in.

+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.

 ## Permissions
 
-Everything is denied by default.
+Everything is denied by default. Two standard QQQ layers apply:
 
-| Permission | Grants |
-|---|---|
-| `sqlWorkbench.hasAccess` | The app, widget, and every workbench endpoint: read-only SQL, EXPLAIN, schema, your notebooks and the shared library, your history |
-| `sqlWorkbench.write` | Write mode (preview and commit) and EXPLAIN ANALYZE |
-| `sqlWorkbench.share` | Publishing your notebooks to the shared library |
-| `sqlWorkbenchAdmin.hasAccess` | The qbit's five tables in the generic QQQ table UI / API (`/qqq/v1/table/...`): **every** user's notebooks (personal ones included), cells, versions, pinned result snapshots (real query data), and the full execution audit |
+1. **Permissions** say which operations a user has on each table (QQQ's per-table `read`, `insert`, `edit`, `delete`) and on the endpoints.
+2. **Record security locks** say which rows. QQQ's core actions enforce them, so they apply to the table UI, the `/qqq/v1` table API, exports, possible-value lookups, processes, and the workbench's own endpoints alike.
 
-The names are configurable (`accessPermissionBaseName`, `writePermissionName`, `sharePermissionName`, `adminPermissionBaseName`).
+| Role | Grant | What it allows |
+|---|---|---|
+| User | `config.getUserPermissionNames()`: `sql_workbench.hasAccess`, plus read/insert/edit/delete on notebooks and cells, read on versions, shares and the audit, and read/edit/delete on pinned results | The app, widget and endpoints (read-only SQL, EXPLAIN, schema). Their own notebooks, read-only access to notebooks shared with them or in the library, and their own execution history. |
+| Writer | `config.getWritePermissionName()` (`sql_workbench.write`) | Write mode (preview and commit) and EXPLAIN ANALYZE. |
+| Sharer | `config.getSharePermissionNames()`: `sql_workbench.share`, plus insert/edit/delete on shares | Sharing their own notebooks with users, groups, or everyone (publishing to the library). |
+| Admin | `config.getAdminPermissionNames()`: the user permissions plus `sql_workbench_admin.hasAccess` | The all-access key: every user's notebooks, cells, versions, pinned results (real query data), shares, and the whole execution audit, and editing any notebook. |
 
-Grant `sqlWorkbenchAdmin.hasAccess` only to administrators or auditors. Ordinary workbench users do not need it: the workbench endpoints check ownership, visibility, and the share permission themselves, then read and write the tables as the system user. Without the admin permission a user cannot reach another user's personal notebook or audit row through the generic table API. Cells, versions, snapshots, and the audit are read-only even for admins (insert, edit, and delete are disabled; only the qbit writes them).
+The names are configurable (`accessPermissionBaseName`, `writePermissionName`, `sharePermissionName`, `adminPermissionBaseName`). Table permissions follow the table names, including any `tableNamePrefix`. QQQ 4.1 does not list `write` and `share` as available permissions, so grant them where you grant roles, for example in an authentication customizer.
 
-`write` and `share` are plain session permissions. QQQ 4.1 does not list them as available permissions, so grant them where you grant roles, for example in an authentication customizer.
+**Security keys.** Call `SqlWorkbenchSecurity.applyToSession(qInstance, session, groups)` from your authentication customizer, after the session's user and permissions are set. It puts these keys in the session:
+
+| Key | Values | Used by |
+|---|---|---|
+| `sql_workbench_user` | the user's id (`QUser.idReference`) | owner locks: a notebook's `ownerUserId` (its children reach it through the notebook) and an execution's `userId` |
+| `sql_workbench_audience` | `user:<id>`, `group:<name>` for each group passed, and `all` | share locks (read only): a share row's `audienceKey` |
+| `sql_workbench_all_access` | `true` for holders of the admin permission | every row |
+
+A session without the access permission gets no keys, so it finds no workbench rows at all, even through code paths that skip table permissions. If the host never calls `applyToSession`, the workbench endpoints add the user and `all` keys themselves, but group shares need the host to pass the groups.
+
+**What the locks and customizers enforce:**
+
+| Table | Read | Write |
+|---|---|---|
+| Notebook | the owner, a share audience of the session, or an admin | the owner or an admin. The owner and visibility are system-managed. |
+| Cell, version, pinned result | as their notebook | the owner or an admin, through the notebook. Versions are append-only. |
+| Share | the notebook's owner, the audience it names, or an admin | the owner or an admin, with the share permission |
+| Execution (audit) | the user who ran it, or an admin | nobody: append-only, only the qbit writes it |
 
 `writeModeEnabled=false` turns write mode off for everyone.
 
+## Record developer panel
+
+With QQQ 4.1.0-RC.4 or later, the qbit registers a **SQL Workbench** panel for a record's developer view (`/app/{table}/{id}/dev` in the Next UI). It shows for tables on an RDBMS backend the workbench targets (honoring `allowedBackendNames` / `excludedBackendNames`), and only to users with `sql_workbench.hasAccess`. It contains:
+
+- A read-only `SELECT` for the record and one for the table (`LIMIT 100`), in the backend's own table and column names (aliased to the QQQ field names), with identifiers quoted and the primary key written as an escaped literal for the dialect.
+- The backend, dialect, database table, and whether read-only sessions use the backend's read-only replica.
+- Links that open each query in the workbench (`/app/sqlWorkbenchRunner?sql=...&backend=...`, the Runner, with the table name prefix applied). The Runner opens the SQL as a new cell and does not run it.
+
+The panel only builds text. What runs is what the user executes, under their workbench permissions; the write permission does not change the panel.
+
+## Administering through the tables
+
+Everything the Runner does can be done and inspected through the tables. Notebooks and the execution audit are in the SQL Workbench app's nav; the others open from a notebook's record view (or by URL). The same customizers run either way.
+
+- **Notebooks**: create, rename, describe, delete (which removes its cells, versions, pinned results, and shares). The record view has an Open in Runner link and lists the notebook's cells, shares, pinned results, versions, and runs. Record actions: Share Notebook and Duplicate Notebook.
+- **Cells**: add (appended at the end, with a generated key), edit, reorder (`sortOrder`), delete. Each change saves a new notebook version, exactly like a save in the notebook UI.
+- **Versions**: read-only history. Restore Version saves the chosen version as a new one.
+- **Shares**: who can read a notebook. `USER` and `GROUP` shares name their audience, matched without regard to case (so user ids and group names must be case-insensitive in the host); `ALL` publishes the notebook to the shared library. The notebook's `visibility` follows its shares.
+- **Pinned results**: relabel or delete. Only pinning a result in the notebook UI creates them.
+- **Execution audit**: read, filter, and export. Nobody can edit or delete it through QQQ.
+
+Notebooks, cells, pinned results, and shares get record-level QQQ audits, so SQL text, result data, and share audiences are not copied into the host's audit tables (whose readers the workbench locks do not reach).
+
 ## Safety model
 
 > **Production: configure `readOnlyCredentials` for every target backend.** Use a dedicated database role with `SELECT` grants only: no write privileges, not a superuser, no `pg_signal_backend` (or MySQL `PROCESS` / `SUPER` / `CONNECTION_ADMIN`). Without it, read-only mode connects as the application's own role and relies on the classifier and the session's `READ ONLY` transaction alone. On H2 / generic backends there is no enforced read-only transaction, so the classifier is the only control. On Postgres a `READ ONLY` transaction still lets the application role call side-effecting functions such as `pg_terminate_backend()` or `pg_cancel_backend()`. `/capabilities` reports `readOnlyCredentials: false` / `readOnlyEnforced: false` per backend so you can check.

+## Adopting in another app
+
+A checklist for adding the workbench to a QQQ application. Each row points to the section above that has the details.
+
+| Item | What to do |
+|---|---|
+| Coordinates | `com.kingsrook.qbits:qbit-sql-workbench`. Current release candidate: `1.0.0-RC.2` (Maven Central, published from `release/1.0`). |
+| QQQ version | QQQ 4.1, `4.1.0-RC.4` or later (qqq#1073: partial edits of child rows under joined locks). Java 21. |
+| Dependencies | `qqq-backend-module-rdbms` comes in transitively. Add `qqq-middleware-javalin` yourself for the REST routes; it is optional in this qbit's POM, and without it no routes are registered. |
+| Frontend | A Next UI (`qqq-frontend-next`) release that renders the `SQL_WORKBENCH` widget: `v1.0.0-RC.13` or later. Other frontends show the app and tables but not the notebook. |
+| Registration | `new SqlWorkbenchQBitProducer().withQBitConfig(config).produce(qInstance)` after your backends are in the instance. The producer registers its own QBit metadata; don't add it by hand. To nest the app (for example under Admin), re-parent `SqlWorkbenchQBitProducer.APP_NAME` after producing. |
+| Storage | Create the six tables on `backendName` before first use ([Storage](#storage)). From RC.1, run the share-table DDL and its backfill ([upgrade](#storage-upgrade-from-100-rc1)). PostgreSQL DDL ships in [docs/ddl/postgres.sql](docs/ddl/postgres.sql) and drops into a Liquibase formatted-SQL changeset; translate it for other databases. Match the snake_case names with a `tableMetaDataCustomizer`. |
+| Targets | Every RDBMS backend in the instance is a target unless you narrow it with `allowedBackendNames` or `excludedBackendNames`. |
+| Secrets | In production, configure `readOnlyCredentials` for each target backend with a SELECT-only database role, and optionally `writeCredentials`. Pass them as `${env.X}` references (the example uses `SQLWB_RO_USER` and `SQLWB_RO_PASSWORD`; the names are yours). The qbit reads no other environment variables. |
+| Permissions | Grant `config.getUserPermissionNames()` to workbench users, plus `getWritePermissionName()` for write mode, `getSharePermissionNames()` for sharing, and `getAdminPermissionNames()` for administrators and auditors only. See [Permissions](#permissions). |
+| Security keys | Call `SqlWorkbenchSecurity.applyToSession(qInstance, session, groups)` in your authentication customizer after setting permissions. Pass the user's groups if you want group shares. |
+| Navigation | The app's home is the dashboard; its nav lists the Runner and the two main tables (Notebooks, the execution audit). The other four tables are child lists on a notebook; keep them out of explicit menus. The processes are record actions on the tables; keep them out of the nav. |
+| ESB and search | Optional: wire `SqlWorkbenchIntegrations.esbTableNames` and `quickSearchTables` into your ESB and Quick Search config ([ESB and Quick Search](#esb-and-quick-search)). |
+| Turning writes off | `withWriteModeEnabled(false)` disables write mode for everyone. |
+| Known limitations | Raw SQL bypasses QQQ security, audits, listeners and automations ([Safety model](#safety-model)). H2 and generic backends have no enforced read-only transaction. Only PostgreSQL DDL ships. Shares are read-only (no shared editing). |
+| Upgrading | From RC.2: the QQQ names became snake_case (`sql_workbench_*`; no DDL). See [UPGRADE.md](UPGRADE.md) for permissions and stored table names. From RC.1: also run the share-table DDL and backfill, grant the new permission lists (the tables no longer rely on the admin `hasAccess` permission alone), call `applyToSession`, and use QQQ `4.1.0-RC.4` or later. |
+
+Nothing in the qbit is specific to one host application.

+# Upgrading
+
+## To 1.0.0-RC.3: snake_case names (metadata only)
+
+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. What changes is the names QQQ uses, and anything your app stored under the old names.
+
+| Kind | Before (RC.1, RC.2) | From RC.3 |
+|---|---|---|
+| Tables (and the notebook possible-value source) | `sqlWorkbenchNotebook`, `sqlWorkbenchCell`, `sqlWorkbenchNotebookVersion`, `sqlWorkbenchResultSnapshot`, `sqlWorkbenchNotebookShare`, `sqlWorkbenchExecution` | `sql_workbench_notebook`, `sql_workbench_cell`, `sql_workbench_notebook_version`, `sql_workbench_result_snapshot`, `sql_workbench_notebook_share`, `sql_workbench_execution` |
+| Enum possible-value source | `sqlWorkbenchShareAudienceType` | `sql_workbench_share_audience_type` |
+| Permissions | `sqlWorkbench.hasAccess`, `sqlWorkbench.write`, `sqlWorkbench.share`, `sqlWorkbenchAdmin.hasAccess`, `sqlWorkbenchNotebook.read` etc. | `sql_workbench.hasAccess`, `sql_workbench.write`, `sql_workbench.share`, `sql_workbench_admin.hasAccess`, `sql_workbench_notebook.read` etc. |
+| Security key types / all-access key | `sqlWorkbenchUser` (`sqlWorkbenchAllAccess`), `sqlWorkbenchAudience` | `sql_workbench_user` (`sql_workbench_all_access`), `sql_workbench_audience` |
+| Joins | `sqlWorkbenchNotebookJoinSqlWorkbenchCell` etc. | `sql_workbench_notebook_join_sql_workbench_cell` etc. |
+
+Unchanged: the `sqlWorkbench` app, the `sqlWorkbenchWidget` widget, the record-action process names, the REST routes, field names, and Java class names.
+
+A `tableNamePrefix` (or QBit namespace) is now normalized to lowercase snake_case and joined with one `_`: `ns` and `ns_` give `ns_sql_workbench_notebook`, and `myNs` gives `my_ns_sql_workbench_notebook`. Prefixed tables follow the same rename.
+
+The old names stay available as `@Deprecated` constants for migration scripts only: `SqlWorkbenchNotebook.LEGACY_TABLE_NAME` (and the same on each entity), `ShareAudienceType.LEGACY_NAME`, and `SqlWorkbenchQBitConfig.LEGACY_*`. They will be removed in 1.1.
+
+### Steps
+
+1. **Backend table names.** If your host mapped the old camelCase names to `sql_workbench_*` (for example with `inferBackendName`), nothing else is needed: the new names are already the backend names, and the mapping becomes a no-op. If your backend tables were really named after the camelCase QQQ names, rename them (`ALTER TABLE "sqlWorkbenchNotebook" RENAME TO sql_workbench_notebook;` and so on) or set the backend table names explicitly.
+2. **Permissions.** Grant the new names. If you set the permission names through the config getters (`getUserPermissionNames()`, `getSharePermissionNames()`, `getAdminPermissionNames()`), this is automatic. If roles live in an identity provider or a permissions table, rename them there. If you pinned the old names in config (`withAccessPermissionBaseName("sqlWorkbench")`), you can keep them, but the table permissions still change.
+3. **Security keys.** `SqlWorkbenchSecurity.applyToSession` sets the new key types. Custom code that put `sqlWorkbenchUser` or `sqlWorkbenchAudience` values in a session must use the new names (`config.getUserSecurityKeyTypeName()` and so on).
+4. **Stored references.** Rename the table names your app stored. A Postgres example, with the usual QQQ table and column names (adjust to your app; run inside one transaction, after a backup):
+
+```sql
+BEGIN;
+CREATE TEMP TABLE swb_rename (old_name TEXT, new_name TEXT) ON COMMIT DROP;
+INSERT INTO swb_rename VALUES
+  ('sqlWorkbenchNotebook',        'sql_workbench_notebook'),
+  ('sqlWorkbenchCell',            'sql_workbench_cell'),
+  ('sqlWorkbenchNotebookVersion', 'sql_workbench_notebook_version'),
+  ('sqlWorkbenchResultSnapshot',  'sql_workbench_result_snapshot'),
+  ('sqlWorkbenchNotebookShare',   'sql_workbench_notebook_share'),
+  ('sqlWorkbenchExecution',       'sql_workbench_execution');
+
+-- audit: QQQ's audit_table holds the QQQ table name
+UPDATE audit_table a SET name = r.new_name FROM swb_rename r WHERE a.name = r.old_name;
+
+-- saved views and saved reports
+UPDATE saved_view v   SET table_name = r.new_name FROM swb_rename r WHERE v.table_name = r.old_name;
+UPDATE saved_report s SET table_name = r.new_name FROM swb_rename r WHERE s.table_name = r.old_name;
+
+-- any app table that stores QQQ table names (for example a search index or a shared-record table)
+-- UPDATE quick_search_index q SET table_name = r.new_name FROM swb_rename r WHERE q.table_name = r.old_name;
+COMMIT;
+```
+
+   Saved views and reports can also name columns of joined tables (`sqlWorkbenchCell.title`) inside their JSON filter or column lists; search those columns for `sqlWorkbench` and replace the table part. Rebuild any search index whose document ids embed table names.
+5. **Frontends.** Links to `/app/sqlWorkbench/sqlWorkbenchNotebook/...` become `/app/sqlWorkbench/sql_workbench_notebook/...`.
+6. **Navigation and the notebook UI.** The app's home (`/app/sqlWorkbench`) is now a dashboard; the notebook editor moved to the Runner (`/app/sqlWorkbenchRunner`, `?notebook=<id>` opens one). Update bookmarks and links that expected the editor on the app page. The nav lists only Notebooks and the execution audit; if your host builds its own menus or nav tests, drop the cell, version, pinned-result and share tables from them (they are child lists on a notebook). Nothing to grant: the Runner and the dashboard use the app's access permission, and Activity by User the admin permission.
+7. **Optional: ESB and Quick Search.** Wire `SqlWorkbenchIntegrations.esbTableNames` and `quickSearchTables` into your configuration (README, "ESB and Quick Search"). Adding tables to Quick Search needs an index rebuild or a basepull for the existing rows.

-| Personal vs shared | A personal notebook is visible only to its owner. The five tables need `sqlWorkbenchAdmin.hasAccess`, which ordinary workbench users do not hold, so `/qqq/v1/table/...` cannot read or write other users' notebooks, cells, versions, pinned snapshots, or audit rows. `NotebookService` and the history endpoint check owner / visibility / share permission in code, then read and write as the system user (`SystemUser`), as `ExecutionAuditor` does for the audit. Cells, versions, snapshots, and the audit have insert / edit / delete disabled; only the qbit writes them. Holders of the admin permission see every user's notebooks and the full audit. |
+| Which rows | Record security locks, enforced by QQQ's core actions and therefore for every entry point (table UI, `/qqq/v1` table API, exports, PVS lookups, processes, the workbench endpoints). Two key types: `sql_workbench_user` (the session's user id; all-access key `sql_workbench_all_access` for admins) and `sql_workbench_audience` (`user:<id>`, `group:<name>` per group, `all`). A notebook's lock is OR(owner lock on `ownerUserId`, read-scoped share lock on `sql_workbench_notebook_share.audienceKey` through the share-to-notebook join); its cells, versions and pinned results lock through their notebook (one and two joins); a share row is readable by the notebook's owner or the audience it names; an execution by its `userId`. Writes evaluate only the write-scoped locks, so being shared with is read-only. The RDBMS module de-duplicates rows that match through several shares (`SELECT DISTINCT`, `COUNT(DISTINCT)`). Hosts call `SqlWorkbenchSecurity.applyToSession` from their authentication customizer; sessions without the access permission get no keys and see no rows. |
+| Invariants | Table customizers, shared by the notebook UI and the tables: the owner is the inserting session (only the system user may insert for someone else); `visibility`, `currentVersion` and dates are system-managed; cells are validated (type, length, key) and appended in order, never move notebooks, and every change writes a version; shares compute `audienceKey`, need the share permission, and keep `visibility` in step; pinned results are only created by pinning and only relabeled; versions and the audit are append-only for everyone but the system user. `NotebookService` runs as the caller through the same actions (flagging a whole-notebook save so it is versioned once) and keeps its explicit owner / share checks as defense in depth; only version bookkeeping and cascades run as the system user, after QQQ authorized the change. |
+| QQQ dependency | Partial updates of child rows (a cell's content, a pinned result's label) pass the joined write locks only with QQQ `4.1.0-RC.4`+ (qqq#1073: locks are validated against the stored row overlaid with the written values). |

- ** Builds the QTableMetaData of the five SQL Workbench tables. Shared by the
- ** component producers and by tests.
+ ** Builds the SQL Workbench tables, joins and record-view widgets. Shared by
+ ** the component producers and by tests.
  **
- ** All tables are protected by the ADMIN permission
- ** (sqlWorkbenchAdmin.hasAccess), not the access permission every workbench
- ** user holds: the generic QQQ table UI / API would otherwise let any user
- ** read other users' personal notebooks, pinned result data and the full
- ** execution audit. The workbench endpoints do their own owner / visibility
- ** checks and then read and write these tables as the system user.
+ ** The tables are ordinary QQQ tables (query, view, edit, export, audits,
+ ** developer mode), secured by QQQ mechanisms rather than by hiding them:
  **
- ** Cells, versions, snapshots and the audit are read-only even for admins
- ** (insert / edit / delete capabilities disabled); only the qbit writes
- ** them. Notebooks stay editable for admins (e.g. to clean up).
+ ** - Permissions: QQQ's per-table read / insert / edit / delete permissions
+ **   (SqlWorkbenchQBitConfig lists them per role).
+ ** - Record security locks, enforced by the core actions and so for every
+ **   entry point (table UI, /qqq/v1 table API, processes, PVS lookups,
+ **   exports): a notebook (and its cells, versions and snapshots) is visible
+ **   to its owner (sql_workbench_user = ownerUserId) OR to an audience it is
+ **   shared with (a share row whose audienceKey is one of the session's
+ **   sql_workbench_audience values); only the owner can change it. An
+ **   execution is visible to its user only. Workbench admins hold the
+ **   all-access key and see every row.
+ ** - Append-only: versions and the execution audit have no insert / edit /
+ **   delete capability, and a customizer rejects those writes in the core
+ **   actions unless the qbit itself (system user) makes them.
+ ** - Customizers keep the notebook invariants for edits made through the
+ **   tables exactly as through the notebook UI (ownership, cell order and
+ **   limits, a new version per change, share keys, library visibility).
