session_narrative: "Short planning session. Resumed from S-2026-0214-2025, ran brainstorming skill for Phase 3 design. Explored full web UI codebase (6 blueprints, 18 templates, 76 tests). Decided Approach A: Metrics Dashboard + Pattern Browser. Patterns get their own /patterns route (removed from /learnings) — justified by D1 (Antifragility) since patterns are the primary antifragile memory. Wrote design doc and 7-task implementation plan with full code. Chose subagent-driven execution but context at 111K forced handover for fresh start."

# Session Handover: S-2026-0214-2129

## Where We Are

Phase 3 design and implementation plan are complete and committed. No code has been written yet — the plan is ready for execution. The plan has 7 tasks with full code snippets, exact file paths, and test cases. Execute using subagent-driven-development skill.

## Work in Progress

### T-058: Watchtower Command Center - Design Spec
- **Status:** started-work
- **Last action:** Wrote design doc and 7-task implementation plan for Phase 3
- **Next step:** Execute the plan at `docs/plans/2026-02-14-phase3-operational-intelligence.md` using subagent-driven-development
- **Blockers:** None
- **Insight:** Patterns deserve a first-class `/patterns` route (not buried in `/learnings`) because D1 (Antifragility) — patterns ARE the antifragile memory

## 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

## Decisions Made This Session

1. **Separate `/patterns` route instead of enhancing `/learnings` in-place**
   - Why: D1 (Antifragility) — patterns are the primary antifragile memory, deserve first-class nav presence. D3 (Usability) — `/learnings` was already overloaded with 3 concepts.
   - Alternatives rejected: Single "Observatory" page (overloaded), enhance patterns in-place on `/learnings` (patterns stay second-class)

2. **Approach A: Metrics Dashboard + Pattern Browser (vs Observatory or Metrics-only)**
   - Why: Clean separation of concerns. `/metrics` under Govern, `/patterns` under Knowledge. Aligns with existing one-concern-per-route pattern.
   - Alternatives rejected: Single Observatory page, Metrics-only with patterns enhanced in-place

3. **Handover instead of executing in-session**
   - Why: At 111K tokens, 7 subagent tasks (~70K additional) would hit ~181K — past the 160K compaction threshold. P-009 demands we respect the budget.

## Things Tried That Failed

Nothing failed this session — it was purely design/planning work.

## Open Questions / Blockers

1. **Warning visibility**: Still untested whether stderr warnings from checkpoint hook appear in Claude Code conversation (carried forward from previous session)
2. **Escalation ladder parsing**: The template uses string matching (`'a ' in ladder`) to detect which steps are active. This is fragile — may need refinement if escalation_ladder field format varies.

## Gotchas / Warnings for Next Session

- The plan has Task 1 (nav update) first which will break imports until Tasks 2+3 create the referenced blueprints. Run all three before testing.
- Web server on :3000 will need restart after code changes
- The plan references exact line numbers — verify they still match before editing (they were accurate as of this commit)
- Use `superpowers:subagent-driven-development` skill for execution

## Suggested First Action

Read the implementation plan at `docs/plans/2026-02-14-phase3-operational-intelligence.md` and execute it using the subagent-driven-development skill. Start with Tasks 1+2+3 together (nav + metrics + patterns), then Tasks 4+5 (learnings cleanup + dashboard), then Task 6 (tests), then Task 7 (restart + smoke test).
