- CLAUDE.md: new "Collaboration" section (plan-first, options-with-marked- optimal-and-why, mockups for design decisions, challenge unsound requests, visual UAT before done, terse otherwise). - CLAUDE.md: clarify release is user-owned in timing, agent-run in execution. - CLAUDE.md + docs/development.md: document the ruff format --check gate step (already enforced in .gitea/workflows/check.yml, was missing from the docs). - CLAUDE.md: refresh the stale footer to point at the now-existing docs/development.md and backend/app/README.md.

Development
How to run Siftlode locally and pass the gate. Conventions for the backend code itself live in
backend/app/README.md.
Run it locally
The whole stack (Postgres + API + worker) comes up from the localdev compose file:
docker compose -f docker-compose.localdev.yml up --build
Browse at http://localhost:8080 (Google login works — the OAuth redirect is
http://localhost:8080/auth/callback). The API runs alembic upgrade head on startup, so the schema
is always current.
For a fast frontend edit loop, run the Vite dev server with HMR against that API:
cd frontend && npm install && npm run dev # http://localhost:5173, proxying the API on :8080
The gate
A change is done when all of this is green. CI runs the same checks server-side
(.gitea/workflows/check.yml), so "main is always green".
Backend
# lint + format check
python -m ruff check --config backend/ruff.toml backend scripts
python -m ruff format --check --config backend/ruff.toml backend scripts
# tests — pure-logic + the DB-backed integration lane, against an ephemeral Postgres.
# The backend tree is bind-mounted, so it always tests your working files.
docker compose -f backend/docker-compose.test.yml up --build --abort-on-container-exit --exit-code-from test
docker compose -f backend/docker-compose.test.yml down -v
The test compose sets SIFTLODE_TEST_REQUIRE_DB=1, which turns a would-be silent skip (no DB, or no
ffmpeg) into a hard failure — so the gate can't print green while the DB-backed tests were quietly not
run. Tests that need a database take the db fixture (backend/tests/conftest.py); the rest are
pure-logic and run without one.
Frontend (from frontend/)
npm run typecheck # tsc x3 (app / node / e2e)
npm run lint # eslint
npm run format:check # prettier
npm run knip # unused exports/deps
npm run test # vitest
Branching
Trunk-based: branch off main, keep the branch gate-green, and land the whole change back to main
in one reviewed step. Migrations are Alembic revisions under backend/alembic/versions; the API
applies them on startup, and the DB-lane rebuilds the schema via alembic upgrade head, so a broken
migration chain fails the tests.
