fix(sql-workbench): consume history inserts once; review nits

The history insert request is parent state and NotebookDraft remounts on
save, restore, duplicate and notebook switch, so the last history SQL was
re-appended on every remount (duplicate cells, injected into other
notebooks, spurious dirty state). The draft now applies each request nonce
once and calls onInsertConsumed, which clears it in the widget.

Also: key the result view and quick chart by executionUuid so paging and
chart state reset per run; show an error instead of "No notebooks yet."
when the notebook list fails; use aria-pressed toggle buttons instead of a
partial tab pattern for My notebooks / Shared library; disable the default
backend select and hide cell move/delete controls when the notebook is not
editable. Regression tests cover save remount, notebook switch, the list
error and the read-only controls.

+# Next UI 1.0.0-RC.10 — preparation
+
+RC10 is being prepared for application testing and **is not yet published**. [RC9](1.0.0-RC.9.md) remains the latest verified public candidate and is immutable. Planned artifacts are `com.kingsrook.qqq:qqq-frontend-next:1.0.0-RC.10` and `ghcr.io/qrun-io/qqq-frontend-next:1.0.0-RC.10`. Public checksums, signatures and image digests will be recorded after delivery verification. Final 1.0 remains held for application soak and explicit owner approval.
+
+## Changes from RC9
+
+- Fix section-hash loss and stale immediate URLs when changing record tabs or views (#989), preserving URL context, return links, focus and history. The baseline eventually restored the tab; this is not a claim of proven tab loss.
+- Preserve search-dialog keyboard focus (#950), WebKit possible-value selections (#978), and authentication loading through logout/provider departure (#984).
+- Add ESB developer views and overview/management controls, with real-backend acceptance. See the [ESB contract](../acceptance/esb.md).
+- Improve browser readiness and diagnostic checks while preserving assertions. The pinned Playwright runner contains the corrected Linux WebKit library; stable-runner migration remains #973. See [change details](unreleased.md).
+
+## Verification
+
+Verification uses source `5e3738b73f14d7ed25580560f3c97b91aed58fce` ([PR21](https://github.com/QRun-IO/qqq-frontend-next/pull/21)) with RC10 metadata and QQQ backend `55b33e6bd7f8cc2aef3b41546ef8409ad307ff05`.
+
+- **1,979 unit tests / 184 files**, typecheck, lint/license (zero errors, five existing warnings), static export, Maven packaging and bundle budgets pass.
+- The actual RC10 JAR passes **85/85** auth/focus/selection/ESB real-backend cases: Chromium, Firefox and WebKit 21 each; mobile and tablet 11 each.
+- Four navigation regressions pass **8/8 in Firefox/WebKit**, using the same JAR's assets with mocked APIs. These are separate from real-backend API coverage.
+
+Both browser reports have zero failures, skips, flaky outcomes or report errors, with retries disabled. All 192 dashboard files are packaged without a mock service worker; Maven and compiled frontend versions are RC10. Served JavaScript and font bytes match the JAR. The primary fixture serves the JAR directly; authentication variants use verified assets extracted from it. These are local candidate checks, not public delivery receipts. PR23 changes test selection and documentation only; production code and test assertions are unchanged from this verified candidate.
+
+## Browser coverage and remaining RC limits
+
+The historical [PR18 run](https://github.com/QRun-IO/qqq-frontend-next/actions/runs/36942612338) failed its touch-coverage gate despite all 2,972 executed cases passing: ESB-001–010 were required but not selected on phone and tablet. The original failed result is retained under [#990](https://github.com/QRun-IO/qqq/issues/990).
+
+[PR23](https://github.com/QRun-IO/qqq-frontend-next/pull/23) corrects selection by adding touch markers to the ten existing ESB tests, preserving production code and every assertion. Its separate focused real-broker run on the PR18 export and QQQ `55b33e6` passed all 20 phone/tablet cases with zero retries, failures, skips, flaky outcomes or report errors. This focused result is not a fresh full hosted matrix pass; full hosted verification remains pending at this preparation checkpoint.
+
+The secondary-browser/tablet RC exception remains documented in [#985](https://github.com/QRun-IO/qqq/issues/985#issuecomment-5943724086) and [#798](https://github.com/QRun-IO/qqq/issues/798#issuecomment-5943457468). No gate, test requirement or exclusion was weakened. This exception does not waive product defects or authorize GA.
+
+Remaining parity, real Auth0/Drive/QuickSight checks, browser investigations, visual review and application soak stay tracked in [#713](https://github.com/QRun-IO/qqq/issues/713), [#985](https://github.com/QRun-IO/qqq/issues/985), [#711](https://github.com/QRun-IO/qqq/issues/711) and [#712](https://github.com/QRun-IO/qqq/issues/712).

+# Next UI 1.0.0-RC.11 — preparation
+
+At this preparation checkpoint, RC11 is being prepared for application testing and **is not yet published**. [RC10](https://github.com/QRun-IO/qqq-frontend-next/releases/tag/v1.0.0-RC.10) remains the latest verified public candidate and is immutable. Planned artifacts are `com.kingsrook.qqq:qqq-frontend-next:1.0.0-RC.11` and `ghcr.io/qrun-io/qqq-frontend-next:1.0.0-RC.11`. Public hashes, signatures and image digests will be recorded after delivery verification. Final 1.0 remains held for application soak and explicit owner approval.
+
+## Changes from RC10
+
+[PR24](https://github.com/QRun-IO/qqq-frontend-next/pull/24), merged source `a1d3e48419812fcb8d47091cb4af315cad4e76e9` (tree-identical to reviewed head `ea73118fcabdf3c08ea8614c8bd0ad63749fb598`), invalidates stale searchable-selector results immediately when input changes (#970), and keeps script-completion suggestions open when a delayed scroll event reports an unchanged position (#954). Actual position changes still dismiss suggestions. No acceptance assertion or gate is weakened.
+
+## Verification checkpoint
+
+PR24's [hosted primary acceptance](https://github.com/QRun-IO/qqq-frontend-next/actions/runs/36954433088) passes on its exact source: 614 cases and 401 required rows. The actual merged source above has the same tree. With RC11 metadata, fresh verification passes **1,984 unit tests / 184 files**, typecheck, lint/license (zero errors, five existing warnings), static export, Maven packaging and bundle budgets. All **192 dashboard files** match the export byte-for-byte, with no mock service worker and matching RC11 frontend/Maven versions.
+
+The actual RC11 JAR passes **125/125 real-backend cases** against QQQ `55b33e6bd7f8cc2aef3b41546ef8409ad307ff05`: 25 each in Chromium, Firefox, WebKit, phone and tablet. These include the 105 auth/focus/selection/ESB cases and 20 selector/completion regression cases. A separate **8/8 record-navigation regressions in Firefox/WebKit** use the same JAR assets with mocked APIs. Both reports have zero failures, skips, flaky outcomes or report errors, with retries disabled. Served versioned JavaScript and font bytes match the JAR. The scoped matrix check passes only the exercised rows; it is not a full hosted matrix result. These local candidate checks are separate from eventual public-artifact verification; no RC10 test count or artifact digest is attributed to RC11.
+
+## Remaining RC limits
+
+Historical observations remain preserved: REC-054 on mobile light expected three completion options but found none; PRC-061 in WebKit left the Casey selection at its placeholder. See [#954](https://github.com/QRun-IO/qqq/issues/954), [#970](https://github.com/QRun-IO/qqq/issues/970) and [RC10 delivery notes](https://github.com/QRun-IO/qqq-frontend-next/releases/tag/v1.0.0-RC.10). The original [PR18 touch-coverage failure](https://github.com/QRun-IO/qqq-frontend-next/actions/runs/36942612338) remains historical evidence. [#990 is complete](https://github.com/QRun-IO/qqq/issues/990#issuecomment-5944836159): PR23’s complete touch report covers all 401 required IDs on each profile, with zero missing, and all ten ESB scenarios pass first attempt on both phone and tablet. That report records **1,149 passes and one unrelated tablet NAV-056 failure**; its full touch gate and whole workflow remain **failed**. [NAV-056 diagnostics remain under investigation](https://github.com/QRun-IO/qqq/issues/985#issuecomment-5944830383), provisionally tracked in [#904](https://github.com/QRun-IO/qqq/issues/904#issuecomment-5944558037), without claiming a shared historical cause. Scoped #990 completion does not imply an all-browser pass or waive that failure.
+
+The documented secondary-browser/tablet RC exception remains under [#985](https://github.com/QRun-IO/qqq/issues/985#issuecomment-5943724086) and [#798](https://github.com/QRun-IO/qqq/issues/798#issuecomment-5943457468); it does not waive new product defects or authorize GA.

+## New features
+
+- SQL Workbench: render the `SQL_WORKBENCH` widget of the [qbit-sql-workbench](https://github.com/QRun-IO/qbit-sql-workbench) QBit as a super-user SQL notebook.
+  - Personal and shared notebooks with SQL and markdown cells, `:parameters`, versions and pinned results.
+  - A CodeMirror 6 editor with dialect highlighting, schema and QQQ-name autocomplete, and formatting.
+  - A typed, sortable, paged result grid with CSV/XLSX/JSON export, quick charts, and EXPLAIN plan trees.
+  - Read-only runs by default, and a two-step write confirmation for users with the write permission.
+  - CodeMirror and the formatter load only on that page (new `lazyChunks` budgets).
 
 ## Product fixes
 
+- Clear remembered query filters and saved-view selections on logout or a detected user identity change. Same-user resumes keep their query state; global appearance, density and legacy column preferences remain intact. This correction awaits its own branch acceptance. [#1006](https://github.com/QRun-IO/qqq/issues/1006)
+- In searchable possible-value fields, invalidate old results immediately when the search term changes, so a debounced request cannot remove an option during its selection. [#970](https://github.com/QRun-IO/qqq/issues/970)
+- Keep code suggestions open when a delayed textarea scroll event reports the position already used for the popup; dismiss them when the scroll position actually changes. [#954](https://github.com/QRun-IO/qqq/issues/954)
 - Preserve focus on the search dialog's Clear control when keyboard interaction occurs before its scheduled initial focus. [#950](https://github.com/QRun-IO/qqq/issues/950)
 - Preserve a clicked possible-value option in WebKit when blurring its search input would scroll the form between mousedown and mouseup. The selected value now reaches process submission and generated output. [#978](https://github.com/QRun-IO/qqq/issues/978)
 - Keep authentication loading until explicit logout finishes, so a late logout response cannot erase cookies from a subsequent successful sign-in. [#984](https://github.com/QRun-IO/qqq/issues/984)

 ## Verification and remaining work
 
-Each linked issue and PR records the source commit, reproduction and scoped verification. Preserve failed full-run snapshots separately from later focused passes; no corrected all-browser pass or release approval is claimed by this changelog. The original causes of the same-user session stall and legacy process-navigation stall remain unresolved in [#952](https://github.com/QRun-IO/qqq/issues/952) and [#960](https://github.com/QRun-IO/qqq/issues/960).
+Current main `5ca3e0b` has a complete [3,010-case first-attempt acceptance pass](https://github.com/QRun-IO/qqq-frontend-next/actions/runs/36989591498): 620 per desktop browser and 575 per touch profile. That run qualifies the main tree before the query-state correction above. The earlier checkpoints below are retained separately.
+
+The [combined acceptance run](https://github.com/QRun-IO/qqq-frontend-next/actions/runs/36942612338) on head `7ff90f1` (the same tree as merge `289eca19`) passed all 2,972 executed cases: 614 each in Chromium, Firefox and WebKit, and 565 each on phone and tablet. All desktop gates covered 401 required rows. The workflow still failed its touch coverage gate because ten ESB rows were not selected; that original failure remains retained under [#990](https://github.com/QRun-IO/qqq/issues/990). After adding the selection markers, a separate native Linux run passed all 20 ESB phone/tablet cases, with zero retries, skips, flaky outcomes or report errors. Its frozen frontend export is unchanged; its freshly rebuilt backend is `55b33e6`. Complete touch collection is 575 cases per profile. The subsequent [complete PR23 outcome](https://github.com/QRun-IO/qqq/issues/990#issuecomment-5944836159) covers all 401 required IDs on each profile with zero missing and all 20 ESB touch cases passing, completing #990. Touch totals are 1,149 passes and one unrelated tablet NAV-056 failure; the full gate and workflow remain failed. [NAV-056 investigation](https://github.com/QRun-IO/qqq/issues/985#issuecomment-5944830383) remains separate, with no shared-cause claim or new waiver.
+
+Each linked issue and PR records the source commit, reproduction and scoped verification. Preserve failed full-run snapshots separately from later focused passes. The broader historical navigation inventory [#904](https://github.com/QRun-IO/qqq/issues/904), same-user session stall [#952](https://github.com/QRun-IO/qqq/issues/952), legacy process-navigation stall [#960](https://github.com/QRun-IO/qqq/issues/960), and original toast-paint uncertainty [#967](https://github.com/QRun-IO/qqq/issues/967) remain open. The [RC10 preparation notes](1.0.0-RC.10.md) retain their historical checkpoint; its [public release entry](https://github.com/QRun-IO/qqq-frontend-next/releases/tag/v1.0.0-RC.10) records final delivery verification. See [RC11 notes](1.0.0-RC.11.md) for the successor candidate. No final-release approval is claimed by these results.
 
 Final 1.0 remains held for real-application soak and explicit owner approval under [#712](https://github.com/QRun-IO/qqq/issues/712). This work does not authorize a QQQ 4.1 release. See the [testing-period policy](1.0-testing.md) and [issue lifecycle](../ISSUE-TRACKING.md).
+
+## Pending standalone branding compatibility (QQQ #1009)
+
+The standalone Node server can route the exact root-relative `branding.logo` and
+`branding.icon` paths published by authentication metadata through fixed backend
+image roles. Local Node `public` files keep precedence; external image URLs and
+Java dashboard serving are unchanged. This does not expose the whole application
+overlay or add a general proxy.
+
+This requires **a QQQ middleware-javalin build containing QQQ #1009's
+`/qqq/branding/logo` and `/qqq/branding/icon` endpoints**. They are absent from
+published **4.1.0-RC.1**. The minimum numbered release is not yet assigned; a
+source build must record the exact backend commit/JAR hashes. Older deployments
+must supply branding through their Node `public` files or an existing external
+image URL. No automatic compatibility with old relative backend assets is claimed.
+
+The preserved standalone qualification against public RC1 remains **5 passed,
+38 failed** out of 43 cases because of missing branding assets. The original
+staging failure is also retained. The corrected cross-repository pairing has
+not yet received its browser qualification; neither #1009 nor #734 is closed by
+focused unit/HTTP results.

 # Next UI security review (QRun-IO/qqq#696)
 
+## Current status — October 4, 2026
+
+This addendum supersedes the historical disposition statements below where noted.
+The September 25 review remains intact as evidence of its original source and scope.
+Current findings and release decisions are tracked in
+[QQQ #696](https://github.com/QRun-IO/qqq/issues/696#issuecomment-5982040326).
+This is a scoped security review, not a certification of ASVS Level 2 compliance.
+
+| Finding | Current disposition |
+| --- | --- |
+| NUI-04: dashboard headers | [#695](https://github.com/QRun-IO/qqq/issues/695) is closed for the Javalin static-export scope, with current-source provider tests and browser evidence. Standalone qualification is separate. |
+| NUI-05: readable session cookie | [#733](https://github.com/QRun-IO/qqq/issues/733) is closed. Next resumes through the backend-owned cookie; the legacy endpoint correction is merged. Material's explicit readable-cookie compatibility mode remains supported. |
+| NUI-06: previous-user browser state | The additional query-filter and saved-view-pointer retention finding is fixed in [#1006](https://github.com/QRun-IO/qqq/issues/1006), merged in frontend `f367756`. Global visual preferences are preserved. |
+| NUI-09: standalone headers | [#734](https://github.com/QRun-IO/qqq/issues/734) and the metadata-derived CSP correction [#1017](https://github.com/QRun-IO/qqq/issues/1017) are closed after scoped qualification and integration. The paired implementation passed 48 standalone first-attempt cases across five profiles. [Frontend PR #40](https://github.com/QRun-IO/qqq-frontend-next/pull/40) merged as `138c3c6d`, tree `328bc322`, exactly matching the qualified combined candidate. Its separate full Javalin acceptance passed 3,015/3,015 first attempts against backend `1d16a70c`. HEAD/304, bounded metadata and Java-customizer limits remain documented in the closeout. |
+| NUI-11: custom CSS | Current code treats application `customCss` as trusted developer configuration and inserts it with `textContent`. It is not filtered by the historical deny-list or sanitized by DOMPurify. CSP and application configuration remain separate controls. |
+| Auth0 token verification | [#1008](https://github.com/QRun-IO/qqq/issues/1008) confirms issuer/audience validation and cache-boundary findings. [Backend PR #1012](https://github.com/QRun-IO/qqq/pull/1012) contains the correction; 164 focused tests passed on its combined backend tree. The exact-head CI passed and the correction merged into backend develop as `fc67393b`. An unconfigured audience remains supported; no audience enforcement is claimed in that configuration. |
+| Signed back-channel logout | [#909](https://github.com/QRun-IO/qqq/issues/909) remains open for stable release delivery. [Backend PR #1021](https://github.com/QRun-IO/qqq/pull/1021) merged the qualified correction into stable main as `9168e434`; its merge tree equals the qualified candidate and the automatic post-merge reactor/sample/static gates passed. Published 4.0.0 remains affected; planned 4.0.1 is not published or artifact-qualified. PR #1018 is closed as superseded, not merged; its original Mongo failure is retained. The corrected 4.1 RC line remains distinct. |
+
+The other scoped finding dispositions remain as reconciled in #696. NUI-10's
+runtime-style exception remains deliberate; it does not allow inline scripts.
+Negative security tests intentionally produce denied-resource and CSP diagnostics.
+A passing test run does not mean those diagnostic arrays are all empty.
+
+### Evidence limits
+
+The reference remains ASVS 4.0.3. Owned identity-provider fixtures do not qualify a
+real Auth0 tenant, MFA or step-up policy, provider-grant revocation, or deployment
+TLS, HSTS and proxy trust. The approved real-provider exclusion remains explicit.
+Configurable TABLE_BASED idle expiration does not prove a 12-hour active / 30-minute
+idle policy. Cookie-prefix and shared-host suitability, generic CSRF/Origin
+protection, all-session revocation, and application-sensitive storage/cache policy
+also remain outside the demonstrated guarantees. These limits are not newly
+confirmed High/Critical exploits and must not be presented as universal compliance.
+
+The 48-case standalone result covers its selected security scope and paired
+candidate backend. Its analytics case uses an owned plugin through the real
+application hook, not a vendor SDK or real account. It does not
+replace full-browser acceptance. The separate 3,015-case Javalin gate qualifies
+the merged PR40 tree; neither result resolves separately tracked browser failures
+or certifies a real provider or deployment. Final 1.0 still requires owner visual
+acceptance and real-application soak.

+  separately. This observer is acceptance-only and adds synchronous logging overhead;
+  leave the variable unset for a control run with the original handler tree. Native and
+  ordinary server logs can still contain session data; keep raw evidence private.
+- **Document/XHR evidence (opt-in).** Set `QQQ_ACCEPTANCE_BROWSER_TRACE=1` locally to
+  attach `browser-boundary.json` through the diagnostics fixture. CI uses `navigation`
+  mode only for the exact NAV023 unique-key and NAV056 application-theme-override cases
+  on WebKit/tablet; other cases, including SEC043, do not opt in through that mode.
+  By default, only `/app/person[/]`, `/app/person/key[/]`, `/app/person/2[/]`, and
+  `/app/person.bulkEdit[/]` documents on configured UI/API origins are observed. To also
+  capture dashboard documents at exactly `/app` and `/app/`, set
+  `QQQ_ACCEPTANCE_BROWSER_TRACE_SESSION=1` alongside `QQQ_ACCEPTANCE_BROWSER_TRACE=1`
+  locally. The session flag alone installs nothing and does not select additional tests;
+  other dashboard paths are not included. Requests are exact method/path matches:
+  GET person metadata, person record 2 and person.bulkEdit process metadata;
+  POST `/qqq/v1/manageSession`, querySavedView init, person query/count and person.bulkEdit init.
+  GET `/qqq/v1/manageSession` is excluded. The helper emits
+  fixed aliases, document UUID/sequence/clocks, native XHR send return/throw, status and
+  terminal events. It never emits URLs, query/hash values, headers, credentials, payloads,
+  error messages or stacks, and adds no request headers or interception. Disabled mode
+  installs no binding or init script. One listener set follows each reused XHR generation.
+  Native OPENED reentry or reuse before the recorder observes the prior `loadend`
+  emits one `xhr-incomplete` marker and suppresses attribution for that instance for
+  its remaining lifetime. This includes overlapping requests and earlier application
+  event listeners; no endpoint, generation or attempt is guessed. Excluded requests
+  retain only completion state so their old events cannot impersonate later selected
+  reuse; no excluded target data is emitted. Native calls and outcomes are preserved.
+  Each document is limited to 512 events plus an overflow marker and 256 selected XHRs;
+  Node retains at most 4096 validated events with invalid/drop counters. Missing delivery,
+  overflow or missing `ready` means incomplete evidence; zero counters do not prove
+  complete delivery. Lifecycle phase is the last
+  observed pagehide/pageshow state, not proof of browser-internal teardown; no unload or
+  beforeunload hooks are added. Snapshotting uses Node memory even after a page fails.
+  Existing diagnostics, assertions and timeouts are unchanged. RSC fetches and document
+  navigation are not XHRs: correlate existing Playwright/server/native traces instead.
+  Send-return disproves a synchronous throw for that invocation; a pageError alone does
+  not prove one. XHR load observes completion in JS, not UI rendering; successful server
+  writes still do not prove receipt. Binding delivery has nonzero overhead and can be
+  lost during destruction. Retain source/export/runner provenance and raw traces privately;
+  passing instrumented cells do not attribute historical failures or establish a fix.

+## Standalone security qualification (#734)

+Preserve the original SEC-034..036 table-authentication requirements alongside the
+header/enforcement rows SEC-038/040 and both SEC-039 provider-metadata cases:
+
+```bash
+QQQ_ACCEPTANCE_MODE=standalone \

+node scripts/acceptance.mjs --grep '\[SEC-(034|035|036|038|039|040)\]'
+```
+
+This bounded selection currently collects 43 cases (nine per desktop, eight per
+phone/tablet; the Auth0 SEC-039 case is desktop-only). It uses the existing partial
+matrix gate, zero retries and strict diagnostics. A passing Javalin run cannot
+qualify this mode. Retain the actual Node response origins, both build identities,
+frontend/backend source and artifact hashes, runtime versions, original failures
+and raw reports. Never use a stale static export to make standalone variants pass.
+The original loaded-branding assertion also remains required; missing standalone
+assets must be investigated, not skipped. Local discovery or unit success is not
+native qualification or issue closeout.
