ducoterra 022da8e2bc feat: scaffold Brain of Reese — FastAPI RAG chat over Postgres 17 + pgvector
Foundation (phase 01, verified):
- FastAPI app: /api/health, /api/suggestions, /api/chat (placeholder),
  static frontend served locally (no CDN)
- Postgres 17 + pgvector via db/Containerfile + compose.yaml
  (podman compose up -d db), Alembic initial migration (documents,
  chunks with vector(768), query_log)
- LLM client targeting https://aipi.reeseapps.com/v1 (turbo/embed);
  scripts/llm_probe.py verified models + 768-dim embeddings live
- Conditional debugpy: imported only when DEBUGPY=1 (attach on demand,
  :5678); logging config for clean single-line logs
- Frontend shell: mobile-first chat + Sources pages, tokens, a11y baselines
- Tests: 24 unit+integration (99% coverage on app/), ruff + pyright clean,
  Playwright smoke E2E (3 tests) against a deterministic mock LLM
- Planning: .agent/PLAN.md (architecture + LOCKED decisions), AGENTS.md,
  6 user stories, 7 phase files (one story / one phase / one Playwright
  suite each)

# AGENTS.md — Operating Rules for All Agents on This Repo
1. **Always read `.agent/PLAN.md` first.** It contains the architecture, the
LOCKED DECISIONS, the UI/UX standards, the data model, and the roadmap.
Do not design anything that contradicts it.
2. **Follow the phased execution protocol in `.agent/phases/`.** Work through
`.agent/phases/todo/` in numeric order. When a phase is complete, move its
file to `.agent/phases/complete/`.
3. **Strictly adhere to the LOCKED DECISIONS** (PLAN §2). If you believe a
LOCKED decision is wrong, stop and flag it — do not silently deviate.
4. **"One Story, One Phase":** each user story in `.agent/user_stories/`
corresponds to a distinct execution phase that includes its own dedicated
Playwright E2E test suite (one test file per story, run in isolation).
5. **"UI Structure Check":** before finalizing any UI component, verify that
it follows the layout principles in `.agent/PLAN.md` §7 (proper container
usage, centered 46rem chat column, full-width tables on Sources — no
skinny wasted-space lists) and meets WCAG 2.1 AA basics (semantic
landmarks, labels, contrast ≥4.5:1, focus-visible, aria-live for the
stream).
6. **"No CDN Rule":** all CSS, JS, fonts, and images must be served statically
from within the FastAPI application. No `<script src="https://…">` or
`<link href="https://…">` tags in HTML templates unless bundled locally.
An integration test enforces this on the index page.
7. **"Debugpy Check":** any new entrypoint must keep the conditional import —
`debugpy` is imported **only** when `DEBUGPY=1` (see
`app/core/debugging.py`); default off, never imported otherwise.
8. **Git protocol:** Git is mandatory. One **atomic, professional commit per
completed phase** (Conventional Commits, e.g. `feat(rag): stream RAG
answers over SSE with source citations`). Always append `--no-gpg-sign`
(the repo also sets `commit.gpgsign=false`). `.agent/` is gitignored by
design — use `git add -f .agent/…` when a commit must record plan changes.
9. **Test gates are non-negotiable:** a phase is complete only when unit +
integration tests pass, `app/` coverage is **>90%**
(`uv run pytest --cov=app --cov-report=term-missing`), and the phase's
Playwright E2E file passes **in isolation**
(`uv run pytest tests/e2e/test_<story>.py -v --no-cov`).
10. **Amply log, visibly feed back:** server-side, log the required
per-turn line (PLAN §9); UI-side, honor the "never stale" feedback
contract (PLAN §7.4).
## Quick reference
```bash
podman compose up -d db # start Postgres 17 + pgvector
cp .env.example .env # once; then edit
uv run alembic upgrade head # apply migrations
uv run uvicorn app.main:app --reload # dev server (add DEBUGPY=1 to debug)
uv run pytest # unit + integration
uv run pytest --cov=app --cov-report=term-missing
uv run playwright install chromium # once
uv run pytest tests/e2e/test_smoke.py -v --no-cov
uv run ruff check . && uv run pyright # lint + types
