# Session Handover: S-2026-0224-1034

## Where We Are

Q&A Phase 2 build is well underway — 4 of 9 tasks completed in prior session (T-262 model, T-263 RAG, T-264 CLI, T-266 UX). This session was a compaction recovery with no new work. 5 tasks remain: T-265 saved answers, T-267 feedback, T-268 multi-turn, T-269 reranking, T-270 healing integration. Three completed tasks (T-262, T-263, T-266) have human ACs pending browser verification.

## Work in Progress

<!-- horizon: now -->

### T-261: "Q&A Phase 2 — model upgrade, RAG quality, framework integration, saved answers"
- **Status:** started-work (horizon: now)
- **Last action:** GO decision recorded. 4 of 9 child tasks completed (T-262, T-263, T-264, T-266).
- **Next step:** Continue building remaining tasks (T-265, T-267)
- **Blockers:** Owner: human (inception task, but GO already decided)
- **Insight:** Phase 2 build velocity is high — 4 tasks in one session

### T-262: "Replace LLM with Qwen3-14B + thinking mode toggle"
- **Status:** work-completed (horizon: now, partial-complete: human ACs pending)
- **Last action:** Replaced PRIMARY_MODEL, added should_think() classifier, streaming thinking tokens, frontend "Thinking... (Ns)" indicator
- **Next step:** Human verifies answer quality and thinking mode behavior in browser
- **Blockers:** None
- **Insight:** Qwen3-14B responds instantly with think=False, ~33 tok/s confirmed

### T-263: "RAG quick wins — prompt, embeddings, chunking"
- **Status:** work-completed (horizon: now, partial-complete: human ACs pending)
- **Last action:** Upgraded system prompt (anti-hallucination), switched to nomic-embed-text-v2-moe (768-dim) via Ollama, added 150-char chunk overlap, added LRU cache (207ms->0ms on cache hit)
- **Next step:** Human verifies answer quality improvement in browser
- **Blockers:** None
- **Insight:** nomic-embed-text-v2-moe was already installed (957MB), no download needed

### T-265: "Saved answers — curated Q&A for retrieval flywheel"
- **Status:** captured (horizon: now)
- **Last action:** Task created from conversation Q3 discussion
- **Next step:** Add Save button, POST endpoint, .context/qa/ directory
- **Blockers:** None
- **Insight:** Flywheel effect — saved answers become first-class retrieval sources

### T-266: "Streaming UX — marked.js, syntax highlighting, copy buttons"
- **Status:** work-completed (horizon: now, partial-complete: human ACs pending)
- **Last action:** Added marked.js + highlight.js + DOMPurify (all local), copy buttons on code blocks, debounced rendering at 100ms, citation styling
- **Next step:** Human verifies markdown rendering, syntax highlighting, copy buttons in browser
- **Blockers:** None
- **Insight:** highlight.js was already loaded from CDN — switched to local for offline capability

### T-267: "User feedback — thumbs up/down on Q&A answers"
- **Status:** captured (horizon: now)
- **Last action:** Task created referencing RQ-5 section 3
- **Next step:** Create web/qa_feedback.py + endpoints + UI buttons
- **Blockers:** None
- **Insight:** Keep buttons subtle and optional to avoid adoption friction

<!-- horizon: next -->

### T-268: "Multi-turn Q&A conversation"
- **Status:** captured (horizon: next)
- **Last action:** Task created referencing RQ-5 section 1
- **Next step:** Wait for model + RAG improvements to stabilize
- **Blockers:** EventSource to fetch is a one-way door — plan carefully
- **Insight:** Client-side history recommended over server-side sessions

### T-269: "Cross-encoder reranking with Qwen3-Reranker"
- **Status:** captured (horizon: next)
- **Last action:** Task created referencing RQ-2 section 1.1
- **Next step:** `ollama pull qwen3-reranker:0.6b`, then integrate into rag_retrieve()
- **Blockers:** Needs model downloaded
- **Insight:** 15-30% precision boost for 0.5GB VRAM — excellent ROI

### T-270: "Healing agent integration — semantic pattern matching via fw ask"
- **Status:** captured (horizon: next)
- **Last action:** Task created referencing RQ-4 sections 4 and 6
- **Next step:** Now unblocked — T-264 (fw ask CLI) is complete
- **Blockers:** None (T-264 dependency satisfied)
- **Insight:** Replaces 126 lines of fragile bash keyword matching with one semantic query

## 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

None — compaction recovery only, no new work.

## Things Tried That Failed

None — no new work this session.

## Open Questions / Blockers

1. T-262, T-263, T-266 have human ACs pending — verify in browser at `http://localhost:3000/search`
2. Push was blocked by D8 (this handover's TODOs) — fixed in this commit

## Gotchas / Warnings for Next Session

- Flask template caching — restart server after template edits
- Vector index rebuild takes ~90s with nomic-embed-text-v2-moe (12,514 chunks, 924 docs)
- Ollama model cold start takes ~20s for Qwen3-14B — first query may be slow
- `fw ask` requires Ollama + vector index to be available (not just web server)

## Suggested First Action

Start T-265 (saved answers) — simple task, no blockers, builds the knowledge flywheel. Or T-270 (healing agent integration) which is now unblocked by T-264.
