session_narrative: "Addressed the verification gap from last session. Built T-122 (verification gate P-011) — update-task.sh now runs shell commands from ## Verification before allowing work-completed. Then completed T-111 (autonomous compact-resume) — PreCompact hook saves emergency handover, SessionStart:compact reinjects structured context. Verification gate proved itself on T-111 completion. All horizon:now tasks done."

# Session Handover: S-2026-0217-1828

## Where We Are

Completed two structural improvements: T-122 (verification gate P-011) and T-111 (autonomous compact-resume lifecycle). The verification gate addresses the pattern of shipping bugs (T-108, T-118, T-121) by running shell commands from `## Verification` before allowing task completion. The compact-resume hooks automate context preservation across compaction events. All horizon:now tasks are done. Remaining tasks are T-107 (next) and T-120 (later).

## Work in Progress

<!-- horizon: next -->

### T-107: Initialize German pronunciation app project
- **Status:** captured (horizon: next)
- **Last action:** No work this session (horizon: next)
- **Next step:** User decides project directory path, then run `fw` setup wizard
- **Blockers:** User decision on directory path
- **Insight:** fw setup wizard validated and bug-free (T-108). Horizon: next — work on this after current priorities

<!-- horizon: later -->

### T-120: Review Google Context Engineering whitepaper against framework
- **Status:** captured (horizon: later)
- **Last action:** No work (explicitly deferred by user)
- **Next step:** Fetch and review whitepaper when user is ready
- **Blockers:** None — intentionally parked
- **Insight:** User created as backlog item, not for active work

## Inception Phases

**2 inception task(s) pending decision** — run `fw inception status` for details.

## 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. **Verification gate design: Post-AC hook running shell commands from ## Verification section**
   - Why: Structural enforcement (framework authority) over advisory skills (agent discipline). Advisory approach failed 3 times.
   - Alternatives rejected: Template-only section (weak — same self-assessment), verification log file (fakeable), two-phase completion (lifecycle complexity)

2. **Compact-resume architecture: PreCompact + SessionStart:compact two-hook approach**
   - Why: Uses existing Claude Code hook points, no custom infrastructure. Emergency handover is 106ms. Structured reinject provides context lossy compaction misses.
   - Alternatives rejected: systemd.path daemon (over-engineered), checkpoint-only (no reinject), manual /resume only (failed repeatedly)

## Things Tried That Failed

1. **Pipe test of post-compact-resume.sh** — `./script | python3` hit BrokenPipeError. Output was valid; the pipe buffering caused the issue. Verified by writing to file instead.

## Open Questions / Blockers

1. **T-111 end-to-end test deferred**: Hooks snapshot at session start. PreCompact and SessionStart:compact hooks wired in settings.json but won't fire until next session. First real compaction will be the live test.
2. Flask still runs without --debug (template changes require restart) — carried over
3. testdev user cleanup — carried over

## Gotchas / Warnings for Next Session

- **New hooks take effect next session**: PreCompact and SessionStart:compact are wired but not yet active. After restart, compaction will auto-generate handover and reinject context.
- **Verification gate is live**: All tasks with `## Verification` section will have commands run on `work-completed`. Tasks without the section pass through (backward compatible).
- **All horizon:now tasks are done**: Only T-107 (next) and T-120 (later) remain active.
- **Emergency handovers created during testing**: S-2026-0217-1817 through S-2026-0217-1821 are test artifacts from timing the emergency handover. LATEST.md is the real handover.

## Suggested First Action

Verify compact-resume hooks work on first real compaction (T-111 end-to-end validation). Then move to T-107 (German pronunciation app) if user is ready to decide on directory path. If no user direction, consider promoting a backlog item or creating new work.
