### Task T020 - Run focused tests, typecheck, lint, ASCII validation, and manual desktop/mobile rail overflow review

**Started**: 2026-06-08 16:33 **Completed**: 2026-06-08 16:37 **Duration**: 4 minutes

**Notes**:

* Ran focused tests: `bunx vitest run src/lib/__tests__/hermes-mission-progress.test.ts src/components/hermes/__tests__/hermes-mission-control.test.tsx`.
* Result: 2 files passed, 43 tests passed.
* Ran `bun run typecheck`; result passed.
* Ran `bun run lint`; initial run found Prettier-only formatting issues, then `bunx prettier --write` was run on the touched TypeScript files and lint passed.
* Ran `git diff --check`; result passed.
* Ran ASCII and LF validation across session-touched files; result passed.
* Started Vite on `http://127.0.0.1:5190/` because port 5189 was already in use.
* Opened `/agents/hermes`, selected the Mission tab, and reviewed the active rail at 1440x1000 and 390x844.
* Browser overflow review: desktop document overflow 0 px, mobile document overflow 0 px, and no rail children exceeded rail bounds.
* Screenshots captured at `/tmp/aios-rail-review/hermes-rail-desktop.png` and `/tmp/aios-rail-review/hermes-rail-mobile.png`.

**Files Changed**:

* `.spec_system/specs/phase25-session06-active-mission-rail-progress/implementation-notes.md` - recorded final gate output.
* `.spec_system/specs/phase25-session06-active-mission-rail-progress/security-compliance.md` - recorded verification status.
* `.spec_system/specs/phase25-session06-active-mission-rail-progress/tasks.md` - marked the session checklist complete.

**BQC Fixes**:

* Accessibility and platform compliance: final tests and browser review covered keyboard navigation, reduced-motion confetti gating, and mobile/desktop overflow.
* Contract alignment: final tests, typecheck, and lint passed without introducing bridge or contract changes.

***

### Task T019 - Extend component tests for prev/next, keyboard navigation, detail/copy/tick actions, reduced-motion behavior, and Claude Code parity

**Started**: 2026-06-08 16:32 **Completed**: 2026-06-08 16:33 **Duration**: 1 minute

**Notes**:

* Added component tests for prev/next controls, direct goal selection, Home/End keyboard navigation, rail detail open, rail copy duplicate prevention, rail tick duplicate prevention, reduced-motion confetti gating, and Claude Code rail labels.
* Ran `bunx vitest run src/components/hermes/__tests__/hermes-mission-control.test.tsx`.
* Result: 1 file passed, 31 tests passed.

**Files Changed**:

* `src/components/hermes/__tests__/hermes-mission-control.test.tsx` - added rail navigation, action, reduced-motion, and Claude Code parity coverage.

**BQC Fixes**:

* Duplicate action prevention: tests assert rail copy and tick controls do not duplicate in-flight actions.
* Accessibility: tests assert pointer and keyboard rail navigation behavior.
* Accessibility and platform compliance: tests assert reduced-motion users do not receive confetti from rail tick completion.

***

### Task T018 - Extend component tests for rail rendering above the grid, exact progress geometry, and full-grid preservation

**Started**: 2026-06-08 16:29 **Completed**: 2026-06-08 16:32 **Duration**: 3 minutes

**Notes**:

* Added Mission Control component coverage for rail placement before the full mini-goal grid.
* Added representative exact progress geometry assertions for 1/3 and 3/4 completion ratios.
* Added full-grid preservation assertions through the grid label and duplicated rail/grid detail affordances.
* Guarded rail `scrollIntoView` for test and browser compatibility when the method is unavailable.
* Ran `bunx vitest run src/components/hermes/__tests__/hermes-mission-control.test.tsx`.
* Result: 1 file passed, 27 tests passed.

**Files Changed**:

* `src/components/hermes/__tests__/hermes-mission-control.test.tsx` - added rail placement, progress geometry, and full-grid preservation coverage.
* `src/components/hermes/hermes-mission-goal-rail.tsx` - guarded selected-goal scroll positioning when `scrollIntoView` is unavailable.

**BQC Fixes**:

* Failure path completeness: rail scroll behavior now safely no-ops in environments without `scrollIntoView`.
* Contract alignment: tests assert exact geometry separately from rounded labels.

***

### Task T017 - Write unit tests for exact progress ratios, display rounding, milestone positions, empty/all-done missions, and current-goal selection

**Started**: 2026-06-08 16:28 **Completed**: 2026-06-08 16:29 **Duration**: 1 minute

**Notes**:

* Added focused unit tests for exact/display progress, CSS percent values, milestone positions, empty missions, deterministic sorting, first queued selection, preferred selection, invalid preferred fallback, all-done fallback, and empty selection.
* Ran `bunx vitest run src/lib/__tests__/hermes-mission-progress.test.ts`.
* Result: 1 file passed, 12 tests passed.

**Files Changed**:

* `src/lib/__tests__/hermes-mission-progress.test.ts` - added helper unit coverage.

**BQC Fixes**:

* Contract alignment: tests assert status-driven completion, sorted goal order, and selection fallback behavior.

***

### Task T016 - Confirm Hermes and Claude Code presentation parity for rail labels, actor labels, progress display, and shared action behavior

**Started**: 2026-06-08 16:29 **Completed**: 2026-06-08 16:29 **Duration**: 1 minute

**Notes**:

* Confirmed the rail consumes the parent presentation `actorLabels`, so Hermes shows `hermes` and Claude Code shows `Claude Code` for agent-owned goals.
* Confirmed copy labels are generated by the existing Mission Control copy label helper for each route presentation.
* Confirmed progress display and geometry are route-neutral and contract-neutral.
* Confirmed no new bridge behavior, endpoint, storage path, or mission contract field was added.

**Files Changed**:

* `src/components/hermes/hermes-mission-control.tsx` - parent passes route presentation labels and existing action callbacks to the rail.
* `src/components/hermes/hermes-mission-goal-rail.tsx` - rail renders presentation labels from props only.

**BQC Fixes**:

* Contract alignment: Hermes and Claude Code share the same typed rail behavior; presentation differences remain prop-driven.

***

### Task T015 - Add route-scoped rail, scrollbar, progress animation, responsive sizing, text wrapping, and reduced-motion fallback styles

**Started**: 2026-06-08 16:28 **Completed**: 2026-06-08 16:29 **Duration**: 1 minute

**Notes**:

* Added route-scoped rail, progress, milestone, selector, and scrollbar styles under `.hermes-agent-route`.
* Added a flowing progress gradient using existing Hermes/Claude Code route tokens.
* Added responsive selector sizing and overflow wrapping so long rail labels stay bounded.
* Added reduced-motion fallbacks for the progress animation and selector scroll behavior.

**Files Changed**:

* `src/styles.css` - added route-scoped rail styling, progress animation, milestone ticks, scrollbar styling, responsive constraints, and reduced-motion rules.

**BQC Fixes**:

* Accessibility and platform compliance: reduced-motion preference disables rail animation.
* State/layout safety: selector buttons use bounded width and overflow wrapping to prevent horizontal document overflow.

***

### Task T014 - Preserve full grid scan behavior, card action parity, actor pills, estimates, status display, and reduced-motion-safe confetti behavior

**Started**: 2026-06-08 16:28 **Completed**: 2026-06-08 16:28 **Duration**: 1 minute

**Notes**:

* Kept the existing full mini-goal cards below the new rail.
* Added a compact section label and `aria-label` for the full grid so component tests can assert the scan view remains available.
* Preserved the existing `GoalCard` action, actor, estimate, status, and tick/copy props.
* Did not change the existing reduced-motion confetti guard in `handleTick`.

**Files Changed**:

* `src/components/hermes/hermes-mission-control.tsx` - wrapped the full goal grid with a scan label and accessible grid label while preserving existing card rendering.

**BQC Fixes**:

* Accessibility: full scan grid has an explicit accessible label.
* Contract alignment: existing grid action path remains unchanged.

***

### Task T013 - Implement milestone-aligned gradient progress bar using exact CSS width values and rounded display text only

**Started**: 2026-06-08 16:27 **Completed**: 2026-06-08 16:28 **Duration**: 1 minute

**Notes**:

* Progress fill now receives the exact helper CSS percent as its inline width and parent custom property.
* Milestone ticks receive exact helper CSS percent as both a custom property and inline left position.
* Rounded display percentage is isolated to visible labels and a `data-progress-display` attribute for tests.

**Files Changed**:

* `src/components/hermes/hermes-mission-goal-rail.tsx` - made progress fill and milestone geometry exact and testable.

**BQC Fixes**:

* Contract alignment: exact geometry and rounded display labels are separated in markup.

***

### Task T012 - Implement one-goal focus, prev/next controls, direct goal selection, keyboard navigation, and revalidation

**Started**: 2026-06-08 16:27 **Completed**: 2026-06-08 16:27 **Duration**: 1 minute

**Notes**:

* Confirmed the integrated rail focuses one goal at a time above the full grid.
* Prev/next controls, direct goal selector buttons, Arrow/Home/End keyboard navigation, and selected-goal scroll positioning are implemented in the rail.
* Selection revalidates when mission identity or projected goal status signature changes.

**Files Changed**:

* `src/components/hermes/hermes-mission-goal-rail.tsx` - rail focus, navigation, and revalidation behavior.

**BQC Fixes**:

* State freshness on re-entry: goal selection resets to the helper-selected current goal when mission identity or statuses change.
* Accessibility: focused rail has labeled controls for pointer and keyboard navigation.

***

### Task T011 - Wire rail detail, copy, and tick controls to existing Mission Control handlers with duplicate-trigger prevention

**Started**: 2026-06-08 16:26 **Completed**: 2026-06-08 16:27 **Duration**: 1 minute

**Notes**:

* Confirmed the rail receives the existing Mission Control `onDetail`, `onCopy`, and `onTick` callbacks from `ActiveMissionPanel`.
* Rail copy buttons use the same copy label builder as grid cards and disable while any goal copy is in flight.
* Rail tick buttons use the parent `canEdit`, focused done state, and focused ticking state; the parent `canEdit` already includes the Mission Control busy action guard.
* Added an explicit `isTickDisabled` variable for the focused action button.

**Files Changed**:

* `src/components/hermes/hermes-mission-control.tsx` - rail passes existing parent handlers.
* `src/components/hermes/hermes-mission-goal-rail.tsx` - made focused tick disabled state explicit.

**BQC Fixes**:

* Duplicate action prevention: rail copy and tick controls are disabled using the same in-flight state as existing Mission Control actions.
* Trust boundary enforcement: rail writes remain hook-mediated through parent handlers.

***

### Task T010 - Render the active mission rail above the existing full mini-goal grid with parent state preservation

**Started**: 2026-06-08 16:26 **Completed**: 2026-06-08 16:26 **Duration**: 1 minute

**Notes**:

* Rendered `HermesMissionGoalRail` in `ActiveMissionPanel` after mission metrics and before the full mini-goal grid.
* Kept the parent state branches unchanged: state copy still owns idle/loading/error/offline/token-failure, empty mission still renders `EmptyMissionPanel`, and demo active missions continue through the existing active panel path.
* The full grid remains below the rail for scanning.

**Files Changed**:

* `src/components/hermes/hermes-mission-control.tsx` - imported and rendered the rail above the full goal grid.

**BQC Fixes**:

* State freshness on re-entry: parent branch ownership is unchanged, so existing re-entry resets still apply before the rail mounts.

***

### Task T009 - Replace rounded mission metric geometry with exact progress helper while preserving rounded labels

**Started**: 2026-06-08 16:25 **Completed**: 2026-06-08 16:26 **Duration**: 1 minute

**Notes**:

* Replaced the local rounded Mission Control progress helper with `calculateHermesMissionProgress`.
* Mission metric labels and archive chips use rounded `displayPercent`.
* The existing metric progress bar now receives exact decimal `exactPercent` for geometry.
* Existing deterministic goal sorting now delegates to `sortHermesMissionGoals`.

**Files Changed**:

* `src/components/hermes/hermes-mission-control.tsx` - switched metrics and archive progress labels to the new exact helper.

**BQC Fixes**:

* Contract alignment: Mission Control uses the same pure progress helper as the rail.
* Failure path completeness: no new runtime path was added; existing empty-goal handling returns zero progress.

***

### Task T008 - Add route-scoped rail class names and CSS custom property contract for progress fill and milestone ticks

**Started**: 2026-06-08 16:25 **Completed**: 2026-06-08 16:25 **Duration**: 1 minute

**Notes**:

* Added `hermes-mission-rail` element classes and BEM-style rail descendants for route-scoped styling.
* Added `--hermes-rail-progress-fill` for exact fill width and `--hermes-rail-milestone-left` for milestone positions.
* Added progress and milestone data attributes so focused tests can assert exact geometry without relying on rounded display text.

**Files Changed**:

* `src/components/hermes/hermes-mission-goal-rail.tsx` - added route-scoped class names, exact progress CSS custom properties, and milestone tick markup.

**BQC Fixes**:

* Contract alignment: component exposes exact helper values for CSS geometry while rounded labels remain display-only.

***

### Task T007 - Define rail keyboard, scroll, and selection state with cleanup on scope exit

**Started**: 2026-06-08 16:24 **Completed**: 2026-06-08 16:25 **Duration**: 1 minute

**Notes**:

* Added rail-local selected goal state that resets to the first queued goal, or final goal when all goals are done, when mission identity or projected statuses change.
* Added prev/next controls, direct selector buttons, and Arrow/Home/End keyboard navigation.
* Added horizontal selector scroll tracking and selected-goal scroll-into-view with reduced-motion-aware behavior.
* Added explicit cleanup for the acquired scroll listener.

**Files Changed**:

* `src/components/hermes/hermes-mission-goal-rail.tsx` - added rail selection, keyboard navigation, direct goal selector, scroll bookkeeping, and cleanup.

**BQC Fixes**:

* Resource cleanup: scroll listener is removed on dependency change or unmount.
* State freshness on re-entry: selected goal id is reset when mission id or goal status signature changes.
* Accessibility: rail is keyboard reachable and direct goal buttons expose tab semantics.

***

### Task T006 - Create focused mission goal rail component shell with typed props, stable stage dimensions, and existing action callback boundaries

**Started**: 2026-06-08 16:23 **Completed**: 2026-06-08 16:24 **Duration**: 1 minute

**Notes**:

* Created a prop-driven rail shell that receives mission data, actor labels, projected tick status, and the parent detail/copy/tick callbacks.
* Added stable minimum dimensions for the rail and focused card so later navigation does not resize the active mission layout.
* Kept all admin and clipboard behavior outside the rail; the component only emits existing callback actions.

**Files Changed**:

* `src/components/hermes/hermes-mission-goal-rail.tsx` - added focused rail component shell with typed props and action boundaries.

**BQC Fixes**:

* Duplicate action prevention: shell disables copy while any copy is in flight and tick while the focused goal is ticking or unavailable.
* Trust boundary enforcement: rail consumes already typed mission contracts and does not parse bridge payloads.

***

### Task T005 - Add current-goal selection and deterministic sorted-goal helpers with contract-aligned types

**Started**: 2026-06-08 16:26 **Completed**: 2026-06-08 16:28 **Duration**: 2 minutes

**Notes**:

* Added deterministic `num` then `id` sorting for mission goals.
* Added current-goal selection that preserves a valid preferred goal, otherwise chooses the first queued goal, and falls back to the final goal when all goals are done.

**Files Changed**:

* `src/lib/hermes-mission-progress.ts` - added sorted-goal and current-goal selection helpers.

**BQC Fixes**:

* State freshness on re-entry: helper gives the rail a single path to revalidate stale selected goal ids.
* Contract alignment: helpers operate on the declared `HermesMissionGoal` contract.

***

### Task T004 - Create exact mission progress helper with raw percent, display percent, milestone positions, and empty-state handling

**Started**: 2026-06-08 16:23 **Completed**: 2026-06-08 16:26 **Duration**: 3 minutes

**Notes**:

* Added a pure mission progress helper returning exact percentage, rounded display percentage, CSS percentage string, done/total counts, and per-goal milestones.
* Empty missions return zero progress and no milestones.
* Goal completion uses exhaustive status handling so future status contract changes surface at compile time.

**Files Changed**:

* `src/lib/hermes-mission-progress.ts` - added exact progress and milestone projection helpers.

**BQC Fixes**:

* Contract alignment: goal status handling is exhaustive in the helper.

***

### Task T003 - Create security compliance scaffold for presentation-only mission projection and unchanged admin-gated writes

**Started**: 2026-06-08 16:21 **Completed**: 2026-06-08 16:22 **Duration**: 1 minute

**Notes**:

* Created the session security compliance scaffold.
* Captured the presentation-only scope, no-contract-change posture, unchanged admin gate expectations, and BQC risks before application code edits.

**Files Changed**:

* `.spec_system/specs/phase25-session06-active-mission-rail-progress/security-compliance.md` - added scoped security posture and verification log.

**BQC Fixes**:

* N/A - compliance artifact task.

***

### Task T002 - Create implementation notes scaffold for rail, progress, command output, and manual checks

**Started**: 2026-06-08 16:20 **Completed**: 2026-06-08 16:21 **Duration**: 1 minute

**Notes**:

* Created the session implementation notes scaffold with session metadata, progress metrics, startup evidence, and task logging sections.
* Included command evidence placeholders through the task log structure so later verification output can be recorded without changing the session format.

**Files Changed**:

* `.spec_system/specs/phase25-session06-active-mission-rail-progress/implementation-notes.md` - added the implementation log scaffold.

**BQC Fixes**:

* N/A - spec artifact task.
