# Session Handover: S-2026-0214-2354

## Where We Are

Phase 4 implementation is 75% complete (6 of 8 tasks done). The scan engine, detection rules, prioritizer, feedback engine, CLI (`fw scan`), cockpit UI, and resume agent integration are all implemented and tested. 151 tests passing. Tasks 7 (data model wiring) and 8 (integration polish) remain.

## Work in Progress

### T-058: Watchtower Command Center - Design Spec
- **Status:** started-work (Phase 4 implementation in progress)
- **Last action:** Completed Tasks 1-6 via subagent-driven development with TDD
- **Next step:** Complete Task 7 (add escalation fields to patterns.yaml, --source/--recommendation-type to add-decision.sh) and Task 8 (final integration tests, visual verification)
- **Blockers:** None
- **Insight:** The scan engine works end-to-end. `fw scan` produces YAML, cockpit renders it with progressive disclosure, control actions shell out to fw CLI. The `scan()` function's try/except ImportError pattern made incremental implementation clean.

## Gaps Register

**3 spec-reality gap(s) being watched** — see `.context/project/gaps.yaml`

- **G-001** [high]: Enforcement tiers are spec-only
- **G-004** [low]: Multi-agent collaboration untested
- **G-005** [medium]: Graduation pipeline has no tooling

Run `fw audit` to check if any trigger conditions are met.

## Decisions Made This Session

1. **Subagent-driven development with fresh agent per task**
   - Why: Plan called for it, user chose it in prior session
   - Alternatives rejected: Manual implementation (context pollution), parallel session

2. **Spec reviewer caught missing git_log in gather_inputs**
   - Why: Plan spec included it but implementer missed it; fixed before proceeding
   - Alternatives rejected: Skipping the fix

3. **Implementer adjusted traceability drift threshold from >=3 to >=2**
   - Why: Plan's test data had only 2 untraced commits but expected detection; mismatch in plan spec
   - Alternatives rejected: Changing the test (threshold change is more defensive)

4. **Deferred Tasks 7-8 to next session due to context budget**
   - Why: At ~150K of 160K context limit; Tasks 7-8 are non-blocking for core functionality

## Things Tried That Failed

None — subagent-driven approach worked cleanly for all 6 tasks.

## Open Questions / Blockers

1. `fw context add-decision` may not support `--source` and `--recommendation-type` flags yet (Task 7)
2. patterns.yaml needs escalation tracking fields (`escalation_step`, `occurrences_at_step`) for escalation advancement rule (Task 7)

## Gotchas / Warnings for Next Session

- Web server running on :3000
- Scan data exists at `.context/scans/LATEST.yaml` — cockpit will render instead of old dashboard
- If cockpit looks wrong, delete `.context/scans/LATEST.yaml` to fall back to old dashboard
- The cockpit `scan_refresh` endpoint calls `fw scan --quiet` which may be slow on first run
- 5 untracked files (screenshots + .playwright-mcp/) — safe to ignore
- Plan file: `docs/plans/2026-02-14-phase4-watchtower-implementation.md` — Tasks 7+8 still to execute

## Suggested First Action

Complete Task 7 (add escalation fields to patterns.yaml, add --source/--recommendation-type to add-decision.sh) then Task 8 (integration tests + visual verification with Playwright).
