session_narrative: "User frustrated about framework quality breakdown. Ran comprehensive validation (4 parallel agents). Found system IS working post-P-010 (94.5% real ACs) but pre-gate tasks had no ACs. Fixed skeleton AC bypass in P-010. Added dispatch preamble to stop agents returning full blobs. Enriched 89 fabric component descriptions."

# Session Handover: S-2026-0220-0956

## Where We Are

User was deeply concerned the framework was breaking down — tasks completing without real ACs, deliverables not working. Ran a full system validation: the framework IS working since Feb 18 (94.5% real ACs, 91% verification sections). The perceived 26% failure rate was from mixing pre-gate and post-gate tasks. Fixed the one real bug (P-010 accepts skeleton text), enforced sub-agent output discipline, and enriched all fabric component descriptions.

## Work in Progress

<!-- horizon: now -->

### T-200: "Discovery layer design — pattern detection, omission finding, insight surfacing (T-194 Phase 4)"
- **Status:** captured (horizon: later)
- **Last action:** Not touched this session
- **Next step:** Needs OE test data before starting
- **Blockers:** Waiting for real project usage data
- **Insight:** None this session

### T-215: "Component Fabric — Watchtower UI page (visual browser + graph)"
- **Status:** work-completed (horizon: now)
- **Last action:** Completed in previous session. 6/6 agent ACs pass, 3 human ACs pending
- **Next step:** Human to review UI quality and check their 3 ACs
- **Blockers:** None — waiting on human review
- **Insight:** Graph needed placeholder nodes for non-enriched edge targets

### T-218: "Enrich fabric component descriptions — replace 89 TODO placeholders"
- **Status:** work-completed (partial — 1 human AC pending)
- **Last action:** Batch-enriched all 89 components from source code analysis. Zero TODOs on /fabric page.
- **Next step:** Human to verify description quality on the /fabric page
- **Blockers:** None
- **Insight:** fw fabric scan creates components with "TODO: describe" as purpose. Two-pass enrichment needed: first pass reads source headers/routes/structure, second pass improves generic fallbacks.

## Inception Phases

**1 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. **P-010 fix: pattern-match skeleton text rather than content-hash**
   - Why: Simple regex catches `[First criterion]` etc. without false positives
   - Alternatives rejected: NLP-based content quality scoring (overkill), checksum comparison (brittle)

2. **Dispatch preamble as mandatory prompt prefix rather than system-level enforcement**
   - Why: Can't modify Claude's Task tool behavior; prompt preamble is the only injection point
   - Alternatives rejected: PostToolUse hook to truncate results (too late — context already consumed)

## Things Tried That Failed

1. **`TaskOutput` with `block: true` for background agents** — Returns full JSONL transcript (100K+ tokens), defeating the purpose of background execution. Use `tail` on output file instead.
2. **`curl -sf` in verification commands** — The `-f` flag causes silent failures on large pages. Use `curl -s` or `python3 urllib` instead.

## Open Questions / Blockers

1. The empty `.fabric/components/.yaml` artifact keeps coming back when `fw fabric scan` encounters components with empty slugs. Should add a filter in the scan script.

## Gotchas / Warnings for Next Session

- Web server needs restart after fabric YAML changes (not hot-reloaded)
- `TaskOutput` returns raw JSONL — always use the dispatch preamble and read output files instead
- T-215 and T-218 both have human ACs pending — owner set to human

## Suggested First Action

Review the /fabric page at http://localhost:3000/fabric and check the human ACs on T-215 and T-218. Then decide what to build next — the framework enforcement chain is solid now.

## Files Changed This Session

- Created: `agents/dispatch/preamble.md` (mandatory sub-agent output discipline)
- Modified: `agents/task-create/update-task.sh` (P-010 placeholder detection)
- Modified: 89 files in `.fabric/components/` (enriched descriptions)
- Deleted: `.fabric/components/.yaml` (empty slug artifact)
- Updated: `MEMORY.md` (added dispatch rules at top)

## Recent Commits

- ddd3220 T-218: Complete — enriched 89 fabric component descriptions, removed empty slug artifact
- d2b486c T-218: Enrich 89 fabric component descriptions — replace all TODO placeholders
- 89e561f T-217: Add mandatory dispatch preamble — agents write to disk, return ≤5 lines
- ff7f0df T-216: Add placeholder text detection to P-010 gate — rejects skeleton ACs like [First criterion]
- bc7eb52 T-012: Fill handover S-2026-0220-0911 — T-215 complete, AC quality audit findings
