# Session Handover: S-2026-0219-0938

## Where We Are

All active tasks cleared — zero tasks in `.tasks/active/`. Completed 8 tasks this session: T-179 inception (auto-restart GO), T-186/T-187/T-188 builds (auto-restart implementation), T-180 build (MCP orphan reaper), T-130 inception (GSD investigation GO), T-120 inception (Google Context Engineering review GO). Three GO decisions produced 5 candidate build tasks for future sessions. All committed and pushed to remote.

## Work in Progress

No active tasks. Backlog of potential build tasks from GO decisions (not yet created as tasks):

**From T-130 (GSD):**
1. 3-level verification (exists/substantive/wired) enhancing P-011
2. Codebase-mapper convention (CONVENTIONS.md) for agent onboarding
3. Research confidence protocol for sub-agent dispatch

**From T-120 (Google Context Engineering):**
4. Memory consolidation protocol (automated dedup + staleness pruning of learnings/patterns)
5. Memory provenance enrichment (confidence levels on learnings)

## Gaps Register

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

- **G-004** [low]: Multi-agent collaboration untested

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

## Decisions Made This Session

1. **T-179: Flag-file + wrapper for auto-restart** — Chose signal file in checkpoint.sh + `claude-fw` wrapper + SessionStart:resume hook. Rejected: claude-auto-resume (rate-limit focused, brittle), exit-code wrapper (bash exit doesn't propagate), unconditional loop (no gating), inotifywait (external dep).

2. **T-130: Cherry-pick 3 GSD patterns** — Chose 3-level verification, codebase-mapper, research confidence protocol. Rejected: wave-based parallelization (requires PLAN.md format), plan-checker (audit+P-011 covers it), locked decisions (overhead without clear benefit).

3. **T-120: Adopt 2 Google concepts** — Chose memory consolidation protocol and provenance enrichment. Rejected: memory-as-a-tool (conflicts with D2 Reliability), vector DB (conflicts with D4 Portability), real-time triggers (cost overhead).

## Things Tried That Failed

1. **`fw doctor` orphan count integer comparison** — `grep -cE` output had embedded newline, causing `[: integer expression expected`. Fixed with `tr -d '[:space:]'` on the count.

## Open Questions / Blockers

1. Should the 5 candidate build tasks from T-130/T-120 GO decisions be created now or on-demand?
2. 19 older inception tasks still flagged for missing docs/reports/ artifacts (pre-convention)
3. `fw promote suggest` has 58 learnings with promotion candidates — periodic review needed

## Gotchas / Warnings for Next Session

- **Web UI on :3000** — Flask app is running; restart after framework changes if needed
- **Hooks snapshot at session start** — T-188 added SessionStart:resume hook; takes effect next session
- **`fw context init` resets focus** — Always re-set focus with `fw context focus T-XXX` after init
- **Zero active tasks** — Must create a task before any Write/Edit (PreToolUse hook blocks)

## Suggested First Action

Create build tasks from the 3 inception GO decisions (T-179, T-130, T-120) and start with the highest-value one. Recommended: **memory consolidation protocol** (from T-120) — addresses the 58 learnings that likely contain duplicates, and is the most impactful single enhancement to project memory quality.

## Files Changed This Session

- Created: `bin/claude-fw`, `agents/mcp/mcp-reaper.sh`, `docs/reports/T-130-gsd-investigation.md`, `docs/reports/T-120-google-context-engineering-review.md`
- Modified: `agents/context/checkpoint.sh` (T-186 signal file), `agents/context/post-compact-resume.sh` (T-188 resume hook), `.claude/settings.json` (T-188 SessionStart:resume), `bin/fw` (T-180 mcp reap + doctor check), `CLAUDE.md` (T-179 auto-restart docs)

## Recent Commits

- 2ba5876 T-130: GSD investigation complete — GO for 3 adoptable patterns
- 4e1cd8e T-180: MCP orphan reaper — detect and kill zombie MCP processes
