chore(agent): track .agent/ planning tree in git
Remove the blanket .agent/ gitignore so the phase roadmap, user
stories, reports, and PLAN.md are versioned with the code. Only
runtime artifacts (.agent/phase-sessions/, .agent/pipeline.log)
remain ignored. Update AGENTS.md git protocol rule to match.

Phase 03 complete. Report:

Phase 03 — Story: Chat RAG Answer (happy path) — COMPLETE (396e4d4)

  • Implemented: app/rag/retriever.py (cosine top-k → parent-doc selection, dedupe, 20k-char cap w/ […truncated…]), app/rag/prompts.py (locked persona + HIGH/DEFLECT builders), LLMClient.chat_stream (+LLMError), POST /api/chat SSE (delta*→done, query_log row, PLAN §9 log line, error event mid-stream, 503 JSON if DB down), UI SSE reader w/ live streaming, source chips→/sources.html, role=alert error banner, always-recovers Send state.
  • Tests: unit (retriever/prompts/SSE/llm) + integration (real Postgres turn, log row, error/503 + mid-turn failure paths) + new Playwright story suite (grounded answer, query_log, raw SSE shape); smoke placeholder test replaced with the real never-stale contract.
  • uv run pytest --cov=app --cov-report=term-missing → 95 passed, TOTAL 98% (chat/llm/prompts/retriever 100%).
  • uv run pytest tests/e2e/test_chat_rag.py -v --no-cov (isolated) → 3 passed; test_smoke.py → 3 passed; test_import_documents.py (regression) → 3 passed.
  • uv run ruff check . → clean; uv run pyright → 0 errors.
  • Fixed defect (scaffold): .kb-banner display:flex overrode the hidden attribute → banner always visible; added [hidden]{display:none!important} + regression assertion. UI verified at 1280px/375px + XSS-escape proof.
  • Deviations: happy-path scope per phase file — LOW-threshold deflection/amber mode intentionally deferred to phase 04 (HIGH/DEFLECT builders + deflected plumbing ready).
  • Next pending: .agent/phases/todo/04_story_honest_deflection.md.
