* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/tasks.md` - Marked T001 complete and added progress summary.

**Verification**:

* Command/check: `if [ -d .spec_system/scripts ]; then bash .spec_system/scripts/analyze-project.sh --json; else bash /home/aiwithapex/.codex/plugins/cache/apex-spec-system/apex-spec/2.1.3-codex/skills/apex-spec/scripts/analyze-project.sh --json; fi`
  * Result: PASS - analyzer reported `current_session` as `phase21-session06-responsive-layout-and-accessibility-pass`, `current_session_dir_exists` true, `monorepo` true, and Session 06 candidate package `apps/web`.
  * Evidence: JSON output included Phase 21 Session 06 as the earliest incomplete candidate and Session 05 in `completed_sessions`.
* Command/check: `sed -n '1,220p' .spec_system/PRD/phase_21/session_06_responsive_layout_and_accessibility_pass.md`
  * Result: PASS - PRD stub declares Session 06, `Package: apps/web`, and scope for responsive focused-surface layout and accessibility.
  * Evidence: Stub status is Not Started and lists the required focused-surface layout deliverables.
* Command/check: `sed -n '1,220p' .spec_system/specs/phase21-session05-quest-board-and-war-room-parity/validation.md`
  * Result: PASS - Session 05 validation result is PASS.
  * Evidence: Validation summary reports tasks complete 21/21, focused suite 62/62 passed, root suite 3154 passed and 1 skipped, and no blockers.

* UI craft check: N/A - setup verification changed only spec-system tracking files.

### Task T002 - Audit focused-surface layout, accessibility, CSS, and browser-test baselines

**Started**: 2026-06-29 20:11 **Completed**: 2026-06-29 20:15 **Duration**: 4 minutes

**Notes**:

* Confirmed `BottomRailExpansionHost` already uses same-instance promotion, dialog semantics, backdrop close, Escape close with higher-overlay preservation, focus restoration, and guarded compact clicks.
* Found Session 06 gaps: no body/document scroll containment, no Tab/Shift+Tab focus cycling, expanded panel content uses `overflow-hidden`, and the focused wrapper needs stronger viewport-safe sizing independent of the cockpit grid.
* Confirmed `Layout.tsx` constrains the desktop bottom rail with fixed/tight row heights, so focused mode must remain fixed-positioned and independent of grid clipping.
* Confirmed existing e2e coverage validates cockpit, orchestration, and War Room surfaces separately, but not the shared focused bottom-rail dialog for Quest Board, Orchestration, and War Room across desktop and mobile projects.

**Files Changed**:

* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/implementation-notes.md` - Recorded T002 baseline audit evidence.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/tasks.md` - Marked T002 complete and updated progress summary.

**Verification**:

* Command/check: `sed -n '1,280p' apps/web/src/components/BottomRailExpansionHost.tsx`
  * Result: PASS - host baseline inspected.
  * Evidence: Source includes fixed expanded positioning, `role="dialog"`, `aria-modal`, close/backdrop controls, Escape listener cleanup, focus restoration, and guarded interactive selector; no scroll-lock or Tab-cycle logic exists yet.
* Command/check: `sed -n '1,260p' apps/web/src/App.tsx`; `sed -n '1,220p' apps/web/src/components/Layout.tsx`
  * Result: PASS - shell and bottom rail baseline inspected.
  * Evidence: App uses three same-instance `BottomRailExpansionHost` wrappers; layout constrains bottom rail with `lg:grid-rows-[minmax(0,1fr)_minmax(340px,36vh)]` and `2xl:grid-rows-[minmax(0,1fr)_340px`.
* Command/check: `sed -n '1,260p' apps/web/src/index.css`; `sed -n '1,320p' apps/web/tests/BottomRailExpansionHost.test.tsx`; `rg -n "bottom-rail|Quest Board|War Room|Orchestration|focused|app-mobile|screenshot|overlap|text fit|accessible" tests/e2e/app.e2e.ts`
  * Result: PASS - CSS, host tests, and browser-test baselines inspected.
  * Evidence: CSS has reusable `mobile-scroll-region`, `text-fit`, and `touch-target`; host tests cover existing open/close/Escape paths; app e2e has no shared focused bottom-rail coverage yet.
* Command/check: `sed -n '1,220p' docs/adr/0001-local-first-npm-workspace.md`; `sed -n '1,240p' docs/adr/0002-cloudflare-worker-war-room.md`
  * Result: PASS - relevant ADR boundaries inspected.
  * Evidence: Local-first runtime and optional Worker relay boundaries remain the governing constraints.
* UI product-surface check: N/A - audit task changed only spec-system tracking files.
* UI craft check: N/A - audit task changed only spec-system tracking files.

### Task T003 - Create the browser evidence ledger with desktop and small viewport slots

**Started**: 2026-06-29 20:15 **Completed**: 2026-06-29 20:16 **Duration**: 1 minute

**Notes**:

* Created a session-local browser evidence ledger with desktop and mobile rows for Quest Board, Orchestration, and War Room focused surfaces.
* Added the planned Playwright command, check list, screenshot slots, and explicit no-certification/no-hosted-claim boundary.

**Files Changed**:

* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/browser-verification.md` - Added pending evidence ledger.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/implementation-notes.md` - Recorded T003 evidence.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/tasks.md` - Marked T003 complete and updated progress summary.

**Verification**:

* Command/check: `sed -n '1,220p' .spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/browser-verification.md`
  * Result: PASS - ledger contains six pending desktop/mobile surface rows.
  * Evidence: Matrix includes Quest Board, Orchestration, and War Room for `app-desktop` and `app-mobile`; checks include dialog, size, overlap, text-fit, focus path, screenshot, and result columns.
* Command/check: Targeted inspection of no-claim language in `browser-verification.md`
  * Result: PASS - ledger states evidence is practical local browser coverage only.
  * Evidence: The scope section excludes formal WCAG certification, physical-device mobile certification, hosted identity proof, hosted collaboration safety, production-hosted validation, remote execution validation, analytics capture, public replay hosting, and trusted erasure.
* UI product-surface check: N/A - ledger is a spec artifact and does not change runtime UI.
* UI craft check: N/A - ledger is a spec artifact and does not change runtime UI.

### Task T004 - Tune the shared focused-surface wrapper for viewport-safe sizing, max-height, panel scrolling, and stable close-control reachability

**Started**: 2026-06-29 20:16 **Completed**: 2026-06-29 20:22 **Duration**: 6 minutes

**Notes**:

* Replaced ad hoc expanded sizing classes with `bottom-rail-focused-shell`, `bottom-rail-focused-card`, and `bottom-rail-focused-panel`.
* Kept the focused header outside the scrollable panel body so the title, focus state, and close control remain reachable while panel content scrolls.
* Preserved same-instance promotion by keeping the existing `children` tree under one `BottomRailExpansionHost` render path.

**Files Changed**:

* `apps/web/src/components/BottomRailExpansionHost.tsx` - Applied focused shell/card/panel classes and made the expanded panel body use the focused scroller.
* `apps/web/src/index.css` - Added viewport-safe focused shell, focused card, and focused panel utility classes.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/implementation-notes.md` - Recorded T004 evidence.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/tasks.md` - Marked T004 complete and updated progress summary.

**Verification**:

* Command/check: `rg -n "bottom-rail-focused-shell|bottom-rail-focused-card|bottom-rail-focused-panel" apps/web/src/components/BottomRailExpansionHost.tsx apps/web/src/index.css`
  * Result: PASS - focused classes are defined and used by the expanded host.
  * Evidence: Host uses the shell/card/panel classes only in expanded mode; CSS defines viewport insets, max-height, full-height card behavior, and contained panel scrolling.
* Command/check: `sed -n '1,280p' apps/web/src/components/BottomRailExpansionHost.tsx`
  * Result: PASS - close controls remain in a shrink-0 header outside the scrollable panel.
  * Evidence: Header is rendered before `bottom-rail-focused-panel`; `children` remains mounted once under `ids.panel`.
* UI product-surface check: PASS - source inspection shows no debug/runtime/scaffolding copy added; visible labels remain product-facing `Focus`, `Focused`, and `Close`.
* UI craft check: PASS - source inspection confirms viewport-safe shell/card sizing and a scrollable focused panel body; browser geometry evidence remains assigned to T017.

### Task T005 - Add lifecycle-scoped background scroll containment with cleanup on scope exit

**Started**: 2026-06-29 20:22 **Completed**: 2026-06-29 20:24 **Duration**: 2 minutes

**Notes**:

* Added an expanded-scope effect that captures existing `documentElement` and `body` `overflow` and `overscrollBehavior` values.
* Applies hidden overflow and contained overscroll only while a bottom-rail surface is expanded.
* Restores all captured values in the cleanup path so close, surface switch, and unmount release the acquired document/body state.

**Files Changed**:

* `apps/web/src/components/BottomRailExpansionHost.tsx` - Added lifecycle-scoped html/body scroll containment.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/implementation-notes.md` - Recorded T005 evidence.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/tasks.md` - Marked T005 complete and updated progress summary.

**Verification**:

* Command/check: `sed -n '100,180p' apps/web/src/components/BottomRailExpansionHost.tsx`
  * Result: PASS - scroll containment effect saves and restores all acquired style values.
  * Evidence: The effect stores `previousRootOverflow`, `previousRootOverscroll`, `previousBodyOverflow`, and `previousBodyOverscroll`, sets contained values, and restores them in the cleanup function.
* Command/check: BQC resource cleanup source inspection for `BottomRailExpansionHost.tsx`
  * Result: PASS - the effect is gated by `isExpanded` and returns cleanup for the exact document/body state it mutates.
  * Evidence: No scroll state is acquired outside expanded scope.
* UI product-surface check: PASS - no visible copy or product claim changed.
* UI craft check: PASS - background cockpit scroll is contained while focused mode owns the viewport; focused content scroll remains inside `bottom-rail-focused-panel`.

### Task T006 - Add modal focus containment and Tab/Shift+Tab cycling with cleanup on scope exit

**Started**: 2026-06-29 20:24 **Completed**: 2026-06-29 20:26 **Duration**: 2 minutes

**Notes**:

* Added a focusable selector for the expanded surface and Tab/Shift+Tab cycling inside the host.
* Preserved higher-layer overlay behavior so a nested summary or drawer can own Escape and Tab while it is above the bottom-rail surface.
* Kept the keydown listener lifecycle scoped to `isExpanded`, with cleanup on close, surface switch, and unmount.

**Files Changed**:

* `apps/web/src/components/BottomRailExpansionHost.tsx` - Added focusable selector, focusable collection helper, and Tab cycling in the expanded keydown listener.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/implementation-notes.md` - Recorded T006 evidence.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/tasks.md` - Marked T006 complete and updated progress summary.

**Verification**:

* Command/check: `sed -n '1,220p' apps/web/src/components/BottomRailExpansionHost.tsx`
  * Result: PASS - focus containment and listener cleanup are present.
  * Evidence: `BOTTOM_RAIL_EXPANSION_FOCUSABLE_SELECTOR` includes native controls and ARIA controls; the keydown effect handles Escape and Tab, cycles between first and last focusable elements, and removes its listener in cleanup.
* Command/check: BQC accessibility/resource cleanup source inspection for `BottomRailExpansionHost.tsx`
  * Result: PASS - focus cycling is bounded to the expanded host and listener cleanup matches listener acquisition.
  * Evidence: `hasHigherOverlayLayer(OVERLAY_LAYERS.bottomRailSurface)` prevents parent focus handling while higher overlays are active.
* UI product-surface check: PASS - no debug/runtime/scaffolding copy added.
* UI craft check: PASS - keyboard users have explicit dialog focus containment and focus restoration remains in the existing close path.

### Task T007 - Refine compact bottom-rail grid and host dimensions

**Started**: 2026-06-29 20:26 **Completed**: 2026-06-29 20:28 **Duration**: 2 minutes

**Notes**:

* Updated the bottom-rail wrapper to use a stable `md:auto-rows-fr` three-column grid.
* Raised compact small-width minimums for Quest Board and War Room to 280px and Orchestration to 440px.
* Added explicit `md:h-full` host sizing so compact desktop panels fill the bottom rail without resizing the row.

**Files Changed**:

* `apps/web/src/App.tsx` - Refined bottom-rail grid and host compact dimensions.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/implementation-notes.md` - Recorded T007 evidence.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/tasks.md` - Marked T007 complete and updated progress summary.

**Verification**:

* Command/check: `rg -n "grid min-h-0|className=\"min-h" apps/web/src/App.tsx`
  * Result: PASS - compact bottom rail uses stable grid rows and explicit host dimensions.
  * Evidence: Bottom rail wrapper includes `md:auto-rows-fr`; host classes are `min-h-[280px] md:h-full md:min-h-0`, `min-h-[440px] md:h-full md:min-h-0`, and `min-h-[280px] md:h-full md:min-h-0`.
* Command/check: Monorepo package scope inspection
  * Result: PASS - modified file is under declared package `apps/web`.
  * Evidence: `apps/web/src/App.tsx` is within the active package boundary.
* UI product-surface check: PASS - no visible product copy changed and no implementation diagnostics were added.
* UI craft check: PASS - compact panels now have stable small-width minimum heights and desktop full-height behavior for scanning.

### Task T008 - Add or refine shared focused-surface and scroll utility classes

**Started**: 2026-06-29 20:28 **Completed**: 2026-06-29 20:29 **Duration**: 1 minute

**Notes**:

* Added shared bottom-rail focused-surface classes beside existing `mobile-scroll-region`, `text-fit`, and `touch-target` utilities.
* Used dynamic viewport height with a `100vh` fallback for browsers without `100dvh` support.
* Added contained vertical scrolling and stable scrollbar gutter to the focused panel body.

**Files Changed**:

* `apps/web/src/index.css` - Added `bottom-rail-focused-shell`, `bottom-rail-focused-card`, and `bottom-rail-focused-panel`.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/implementation-notes.md` - Recorded T008 evidence.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/tasks.md` - Marked T008 complete and updated progress summary.

**Verification**:

* Command/check: `rg -n "bottom-rail-focused|mobile-scroll-region|text-fit|touch-target" apps/web/src/index.css`
  * Result: PASS - shared focused-surface utilities are present with existing responsive/accessibility utilities.
  * Evidence: Output shows focused-shell, focused-card, and focused-panel definitions in `apps/web/src/index.css`.
* Command/check: Targeted CSS inspection of `apps/web/src/index.css`
  * Result: PASS - focused shell uses viewport-safe inset and max dimensions; focused panel uses contained vertical scrolling.
  * Evidence: CSS defines `inset: clamp(...)`, `max-height: calc(100dvh - ...)`, a `100vh` fallback, `overflow-y: auto`, `overscroll-behavior: contain`, and `scrollbar-gutter: stable`.
* UI product-surface check: PASS - CSS-only utility change adds no visible copy or product claims.
* UI craft check: PASS - focused surface sizing and scroll behavior are centralized and reusable by the host.

### Task T009 - Adjust cockpit layout constraints only where needed to prevent focused surfaces from being clipped by the shell grid

**Started**: 2026-06-29 20:29 **Completed**: 2026-06-29 20:30 **Duration**: 1 minute

**Notes**:

* Increased the desktop bottom-row constraint from a tight 340px baseline to 360px/38dvh and 380px on 2xl screens.
* Increased the stacked bottom rail minimum to align with the Orchestration compact host minimum.
* Kept the focused surface viewport-owned through fixed positioning in `BottomRailExpansionHost`, so the shell grid does not own expanded sizing.

**Files Changed**:

* `apps/web/src/components/Layout.tsx` - Tuned bottom-row grid constraints and bottom rail minimum height.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/implementation-notes.md` - Recorded T009 evidence.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/tasks.md` - Marked T009 complete and updated progress summary.

**Verification**:

* Command/check: `sed -n '1,120p' apps/web/src/components/Layout.tsx`
  * Result: PASS - shell grid constraints were adjusted only around the bottom rail row.
  * Evidence: Large-screen rows now use `minmax(360px,38dvh)`, 2xl rows use `380px`, and bottom rail section uses `min-h-[440px]`.
* Command/check: Monorepo package scope inspection
  * Result: PASS - modified file is under declared package `apps/web`.
  * Evidence: `apps/web/src/components/Layout.tsx` is within the active package boundary.
* UI product-surface check: PASS - no visible copy or product claim changed.
* UI craft check: PASS - compact bottom rail has more stable vertical room, and expanded mode remains independent of cockpit-grid clipping through the fixed host.

### Task T010 - Extend host unit tests for sizing classes, scroll-lock cleanup, focus containment, and higher-layer Escape preservation

**Started**: 2026-06-29 20:30 **Completed**: 2026-06-29 20:36 **Duration**: 6 minutes

**Notes**:

* Added host tests for focused shell/card/panel classes and scrollable expanded panel body.
* Added scroll-lock tests proving html/body overflow and overscroll values are restored after close and unmount.
* Added Tab and Shift+Tab focus cycling coverage while preserving the existing higher-layer Escape test.

**Files Changed**:

* `apps/web/tests/BottomRailExpansionHost.test.tsx` - Added focused sizing, scroll cleanup, and focus containment tests.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/implementation-notes.md` - Recorded T010 evidence.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/tasks.md` - Marked T010 complete and updated progress summary.

  * Result: PASS - 1 test file passed.
  * Evidence: `apps/web/tests/BottomRailExpansionHost.test.tsx` passed 21/21 tests.
* Command/check: Targeted inspection of `apps/web/tests/BottomRailExpansionHost.test.tsx`
  * Result: PASS - tests cover focused classes, scroll cleanup, focus cycling, and higher-layer Escape preservation.
  * Evidence: New cases assert `bottom-rail-focused-shell`, `bottom-rail-focused-card`, `bottom-rail-focused-panel`, restored document/body styles, and Tab boundary cycling.
* UI product-surface check: PASS - tests assert product-facing focus/close behavior and add no runtime UI copy.
* UI craft check: PASS - tests protect viewport-safe focused sizing and keyboard containment behavior.

### Task T011 - Extend shell integration tests for all three expanded surfaces, compact fallback, focus return, and single mounted panel trees

**Started**: 2026-06-29 20:36 **Completed**: 2026-06-29 20:38 **Duration**: 2 minutes

**Notes**:

* Added shell coverage that iterates Quest Board, Orchestration, and War Room focused-surface hosts.
* Verified compact panels exist before expansion, openers are touch-sized and labelled, focused dialogs use the shared shell class, close controls are touch-sized, and focus returns to the opener.
* Reused the single-mounted-tree assertion across all three surfaces.

**Files Changed**:

* `apps/web/tests/CockpitShell.test.tsx` - Added all-surface focused dialog and compact fallback integration test.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/implementation-notes.md` - Recorded T011 evidence.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/tasks.md` - Marked T011 complete and updated progress summary.

  * Result: PASS - 1 test file passed.
  * Evidence: `apps/web/tests/CockpitShell.test.tsx` passed 14/14 tests.
* Command/check: Targeted inspection of `apps/web/tests/CockpitShell.test.tsx`
  * Result: PASS - shell integration covers all three focused surfaces.
  * Evidence: New test iterates `quest-board`, `orchestration`, and `war-room`, checks compact panels, dialog ARIA, focused classes, close controls, focus return, and `expectSingleBottomPanelTrees()`.
* UI product-surface check: PASS - test checks product-facing accessible names and no debug copy was added.
* UI craft check: PASS - shell test protects compact fallback and focused dialog behavior across all three panels.

### Task T012 - Extend mobile accessibility tests for focused bottom-rail labels, touch targets, close controls, focus return, and no-certification boundaries

**Started**: 2026-06-29 20:38 **Completed**: 2026-06-29 20:40 **Duration**: 2 minutes

**Notes**:

* Added mobile accessibility coverage that iterates Quest Board, Orchestration, and War Room focused surfaces.
* Verified opener labels, touch targets, dialog semantics, close labels, close touch targets, focus return, and no formal certification copy.

**Files Changed**:

* `apps/web/tests/MobileAccessibility.test.tsx` - Added focused bottom-rail accessibility/no-certification test.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/implementation-notes.md` - Recorded T012 evidence.
* `.spec_system/specs/phase21-session06-responsive-layout-and-accessibility-pass/tasks.md` - Marked T012 complete and updated progress summary.

* UI product-surface check: PASS - test asserts no formal certification or production-hosted validation language is introduced in the focused surfaces.
* UI craft check: PASS - test protects touch targets, dialog labels, and focus return for mobile accessibility expectations.

### Task T013 - Add desktop/mobile browser checks for expanded Quest Board, Orchestration, and War Room size, overlap, text fit, and screenshots

**Started**: 2026-06-29 20:40 **Completed**: 2026-06-29 20:45 **Duration**: 5 minutes

**Notes**:

* Added a shared Playwright focused-surface helper for Quest Board, Orchestration, and War Room.
* The helper checks dialog semantics, focused classes, close labels, size, close/panel overlap, accessible names, visible text fit, privacy-safe text, horizontal overflow, no certification copy, Tab/Shift+Tab containment, Escape close, focus return, and screenshot attachment.
* Added the test to the app e2e suite so it runs in both `app-desktop` and `app-mobile` projects.

**Files Changed**:

* `tests/e2e/app.e2e.ts` - Added focused bottom-rail helper and desktop/mobile app test.
