The session added a one-goal-focused rail above the existing full mini-goal grid, exact progress geometry helpers, milestone-aligned fill math, keyboard and pointer navigation, shared detail/copy/tick action paths, route-scoped styling, and focused test coverage for Hermes and Claude Code presentation parity. The result keeps the existing Mission Control write contract unchanged while making the active mission surface easier to scan and operate. *** ## Deliverables ### Files Created | File | Purpose | Lines | | --------------------------------------------------------------------------------------------- | ------------------------- | ----- | | `.spec_system/specs/phase25-session06-active-mission-rail-progress/validation.md` | Session validation report | \~110 | | `.spec_system/specs/phase25-session06-active-mission-rail-progress/IMPLEMENTATION_SUMMARY.md` | Session closeout summary | \~90 | ### Files Modified | File | Changes | | ------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------- | | `src/lib/hermes-mission-progress.ts` | Added exact progress helpers, sorted-goal normalization, milestone projection, and current-goal selection. | | `src/lib/__tests__/hermes-mission-progress.test.ts` | Added helper coverage for exact ratios, labels, milestone positions, and selection fallback behavior. | | `src/components/hermes/hermes-mission-goal-rail.tsx` | Added the focused rail UI, navigation controls, keyboard handling, and exact progress geometry. | | `src/components/hermes/hermes-mission-control.tsx` | Rendered the rail above the full grid and switched Mission Metrics to the exact progress helper. | | `src/components/hermes/__tests__/hermes-mission-control.test.tsx` | Extended component coverage for rail placement, geometry, navigation, action parity, reduced motion, and Claude Code parity. | | `src/styles.css` | Added route-scoped rail, progress, milestone, selector, and reduced-motion styles. | | `.spec_system/specs/phase25-session06-active-mission-rail-progress/implementation-notes.md` | Recorded command output, manual review notes, and task completion evidence. | | `.spec_system/specs/phase25-session06-active-mission-rail-progress/security-compliance.md` | Recorded the session security review for presentation-only changes. | | `.spec_system/specs/phase25-session06-active-mission-rail-progress/tasks.md` | Marked all 20 tasks complete. | | `.spec_system/PRD/phase_25/PRD_phase_25.md` | Marked Session 06 complete and updated phase progress. | | `.spec_system/state.json` | Cleared the active session, recorded completion, and kept Phase 25 in progress. | | `package.json` | Bumped the patch version from `0.1.284` to `0.1.285`. | *** ## Technical Decisions 1. **Exact geometry stayed in a helper**: Progress math lives in `src/lib/` so the rail can render precise CSS widths while keeping the logic unit testable. 2. **The rail stayed presentation-only**: Existing Mission Control callbacks handle detail, copy, and tick actions so the new surface does not widen the admin-gated write boundary. *** ## Test Results | Metric | Value | | ----------------------- | -------------------------------------------- | | Focused session tests | 43 passed / 43 total | | Typecheck | Passed | | Lint | Passed | | Diff check | Passed | | ASCII and LF validation | Passed | | Manual browser review | Passed on desktop and mobile overflow checks | *** ## Lessons Learned 1. Active mission hierarchy is much easier to scan when the current goal is isolated above the full card grid. 2. Exact CSS geometry and rounded display labels need separate data paths so progress math stays trustworthy. *** ## Future Considerations 1. Session 07 can build on the rail by adding archive reactivation and set active actions without changing the geometry model. 2. Keep future presentation upgrades route-scoped so Hermes and Claude Code continue to share the same behavior contract. *** ## Session Statistics * **Tasks**: 20 completed * **Files Created**: 2 * **Files Modified**: 12 * **Tests Added**: 2 * **Blockers**: 0 resolved --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase25-session06-active-mission-rail-progress/implementation_summary.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
