# Session Handover: S-2026-0225-1126

## Where We Are

Completed T-276 (deploy skills) and started T-277 (first deployment). Fixed a health endpoint bug where index_stats() triggered a full index rebuild causing timeouts. Code pushed to OneDev. Currently executing first deployment of Watchtower to Ring20 Swarm cluster.

## Work in Progress

<!-- horizon: now -->

### T-261: "Q&A Phase 2 — model upgrade, RAG quality, framework integration, saved answers"
- **Status:** started-work (horizon: now, owner: human)
- **Last action:** All child tasks completed in prior sessions
- **Next step:** Human reviews all tasks in browser, marks human ACs
- **Blockers:** Owner: human (inception task)
- **Insight:** Full Phase 2 delivered across 4+ sessions

### T-262: "Replace LLM with Qwen3-14B + thinking mode toggle"
- **Status:** work-completed (horizon: now, partial-complete: human ACs pending)
- **Last action:** Completed in prior session
- **Next step:** Human verifies in browser at http://localhost:3000/search
- **Blockers:** None
- **Insight:** Model names now config-driven (T-273)

### T-263: "RAG quick wins — prompt, embeddings, chunking"
- **Status:** work-completed (horizon: now, partial-complete: human ACs pending)
- **Last action:** Completed in prior session
- **Next step:** Human verifies in browser
- **Blockers:** None
- **Insight:** Embedding model/DB path now config-driven (T-273)

### T-265: "Saved answers — curated Q&A for retrieval flywheel"
- **Status:** work-completed (horizon: now, partial-complete: human ACs pending)
- **Last action:** Completed in prior session
- **Next step:** Human verifies in browser
- **Blockers:** None
- **Insight:** None

### T-266: "Streaming UX — marked.js, syntax highlighting, copy buttons"
- **Status:** work-completed (horizon: now, partial-complete: human ACs pending)
- **Last action:** Completed in prior session
- **Next step:** Human verifies in browser
- **Blockers:** None
- **Insight:** None

### T-267: "User feedback — thumbs up/down on Q&A answers"
- **Status:** work-completed (horizon: now, partial-complete: human ACs pending)
- **Last action:** Completed in prior session
- **Next step:** Human verifies in browser
- **Blockers:** None
- **Insight:** None

### T-271: "Fix budget-gate stale critical status trap"
- **Status:** started-work (horizon: now, owner: human)
- **Last action:** Fixed in prior session
- **Next step:** Human completes: `fw task update T-271 --status work-completed --force`
- **Blockers:** Human-owned task
- **Insight:** None

### T-273: "Production readiness — WSGI, health endpoint, config, error handling"
- **Status:** work-completed (horizon: now, partial-complete: 3 human ACs pending)
- **Last action:** Completed in prior session. Health endpoint fixed this session (was blocking on stale index rebuild).
- **Next step:** Human verifies UI loads with gunicorn, health shows correct status
- **Blockers:** None
- **Insight:** Health check must never trigger index rebuild — use lightweight DB check only

### T-274: "Scaffold Watchtower deployment — Dockerfile, compose, Traefik routes"
- **Status:** work-completed (horizon: now, partial-complete: 3 human ACs pending)
- **Last action:** Completed in prior session
- **Next step:** Human verifies Docker image starts, Q&A works in container
- **Blockers:** None
- **Insight:** OneDev buildspec custom tags can't be yaml.safe_load'd

### T-275: "Pre-deploy quality gate — audit section + gated fw deploy"
- **Status:** work-completed (horizon: now, partial-complete: 2 human ACs pending)
- **Last action:** Excluded deployment section from default audit (opt-in only via --section deployment)
- **Next step:** Human verifies audit output clear and actionable
- **Blockers:** None
- **Insight:** Deployment audit must be opt-in to avoid blocking pre-push hooks during development

### T-276: "Deploy skills — /deploy-check, /rollback commands"
- **Status:** work-completed (partial-complete: 2 human ACs pending)
- **Last action:** Created both skills, all 8 agent ACs pass, committed
- **Next step:** Human tests /deploy-check and /rollback in practice
- **Blockers:** None
- **Insight:** Skills auto-discovered from .claude/commands/ — no settings.json registration needed

### T-277: "First deployment — Watchtower to Ring20 production"
- **Status:** started-work (horizon: now)
- **Last action:** Fixed health endpoint bug, committed clean state, pushed to OneDev, started deployment sequence
- **Next step:** Build Docker image, create Swarm stack, sync Traefik routes, verify
- **Blockers:** None — all prerequisites done
- **Insight:** First deployment needs docker stack deploy (CI/CD uses service update which requires existing stack)

### T-278: "Harvest deployment learnings — templates to learnings.yaml"
- **Status:** captured (horizon: now)
- **Last action:** Task created in prior session
- **Next step:** Start after T-277 (needs real deployment experience)
- **Blockers:** T-277
- **Insight:** 6 template learnings (L-BUILD-01 through L-TRF-02) to harvest

<!-- horizon: next -->

### T-268: "Multi-turn Q&A conversation"
- **Status:** work-completed (horizon: next, partial-complete: human ACs pending)
- **Last action:** Completed in prior session
- **Next step:** Human tests multi-turn in browser
- **Blockers:** None
- **Insight:** One-way door: EventSource to fetch+ReadableStream

### T-269: "Cross-encoder reranking with Qwen3-Reranker"
- **Status:** work-completed (horizon: next, partial-complete: human AC pending)
- **Last action:** Infrastructure built with graceful fallback
- **Next step:** Install reranker model when available in Ollama registry
- **Blockers:** Model not in Ollama registry
- **Insight:** Auto-activates via _rerank_available() check

## Inception Phases

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

## Gaps Register

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

- **G-004** [low]: Multi-agent collaboration untested
- **G-011** [low]: PostToolUse hooks are advisory-only — cannot block actions

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

## Decisions Made This Session

1. **Health endpoint: lightweight DB check instead of index_stats()**
   - Why: index_stats() calls _get_db() which triggers full index rebuild when stale, blocking health check for minutes
   - Alternatives rejected: Adding timeout to health check (masks the problem), skipping embeddings check entirely (loses useful info)

## Things Tried That Failed

1. **Health endpoint hanging on /health** — index_stats() triggers build_index() via _get_db() when DB is stale. Fixed by checking _db directly without triggering rebuild.

## Open Questions / Blockers

1. First deployment requires manual docker stack deploy (CI/CD buildspec uses service update, not stack deploy)
2. Traefik routes need manual sync to both nodes (.51 and .53)
3. 8 Q&A Phase 2 tasks still have human ACs pending browser verification

## Gotchas / Warnings for Next Session

- Health endpoint must never call index_stats() or _get_db() — they trigger full index rebuild
- First Swarm deployment needs `docker stack deploy`, not `docker service update`
- Deployment audit section is opt-in only (`--section deployment`) — excluded from default audit
- Flask dev server is single-threaded — long-running requests block everything
- SIGPIPE (exit 141) with piped grep -q — avoid in verification commands

## Suggested First Action

Continue T-277: build Docker image via docker-builder, create Swarm stack with `docker stack deploy`, sync Traefik routes, verify health at FQDN.

## Files Changed This Session

- Created: `.claude/commands/deploy-check.md`, `.claude/commands/rollback.md`
- Modified: `web/app.py` (health endpoint fix), `.context/` state files, `.tasks/` status updates
