# Session Handover: S-2026-0220-0006

## Where We Are

All actionable work is complete. This short post-compaction session fixed a data corruption bug (learnings.yaml broken by add-learning script) and added structural regression testing (YAML parse validation in audit). All HIGH risks have implemented controls. Only horizon: later tasks remain.

## Completed This Session

- **T-206:** Fixed `fw context add-learning` — two bugs: grep pattern expected wrong indentation (IDs always restarted at L-001), awk output nested entries under previous entry. Re-indexed 3 corrupted entries (L-059/L-060/L-061). Watchtower learnings page restored (59 entries).
- **T-207:** Added YAML parse validation to audit structure section (CTL-027). All 10 project YAML files validated with `yaml.safe_load` every 30 min. Broken YAML = FAIL. Would have caught T-206 the day it was introduced.

## Work in Progress

<!-- horizon: later -->

### T-191: "Component Fabric — structural topology system for codebase self-awareness"
- **Status:** started-work (horizon: later)
- **Last action:** Parked by human request (prior session)
- **Next step:** Re-engage when human has appetite for inception exploration
- **Blockers:** Needs human engagement
- **Insight:** None new this session

### T-200: "Discovery layer design — pattern detection, omission finding, insight surfacing (T-194 Phase 4)"
- **Status:** captured (horizon: later)
- **Last action:** Untouched
- **Next step:** Start when OE test data accumulates over multiple sessions
- **Blockers:** Needs OE data volume
- **Insight:** None

## 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. **YAML parse errors should be FAIL, not WARN**
   - Why: Silent data loss (Watchtower shows empty page) is not acceptable as a warning-level issue
   - Alternatives rejected: WARN (too weak — page looks broken to user with no indication why)

## Things Tried That Failed

1. **Python `print()` without `sys.exit(1)` in audit check** — parse error was printed but exit code stayed 0, so audit saw it as PASS. Fixed by adding explicit `sys.exit(1)` after error print.
2. **`fw audit | grep -q` in verification** — exit 141 (SIGPIPE) because `grep -q` closes pipe early. Fixed with `bash -c` wrapper using `grep -c > /dev/null`.

## Open Questions / Blockers

1. ~20 inception tasks lack research artifacts (pre-C-001 rule) — historical noise, low priority
2. `add-decision` and `add-pattern` scripts may have similar indentation bugs — not verified this session

## Gotchas / Warnings for Next Session

- Web server at :3000 needs restart for Python changes (not in debug mode)
- Audit processes can stack across sessions — check `ps aux | grep audit` before running
- Pre-push audit takes ~5 minutes

## Suggested First Action

No horizon: now tasks remain. Options:
1. Check if `add-decision` and `add-pattern` have the same indentation bug as `add-learning` (L-047 pattern)
2. Promote T-191 or T-200 to horizon: now if ready to engage
3. Start new work — framework is in good shape

## Files Changed This Session

- Modified: `agents/context/lib/learning.sh` (grep pattern + awk indentation fix)
- Modified: `.context/project/learnings.yaml` (re-indexed L-059/L-060/L-061)
- Modified: `agents/audit/audit.sh` (YAML parse validation in structure section)
- Modified: `.context/project/controls.yaml` (CTL-027 registered)
- Created: `.tasks/completed/T-206-*` (add-learning bug fix)
- Created: `.tasks/completed/T-207-*` (YAML parse audit check)
