Quick start

From the ai-know repo root:

docker compose up --build
# One-shot: apply the schema.
docker compose exec api alembic upgrade head
curl http://localhost:8090/health
# → {"status":"ok","version":"0.1.0","environment":"dev"}
curl http://localhost:8090/health/ready
# → {"status":"ok",...,"database":"ok","redis":"ok"}

Host ports: API 8090, Postgres 5433, Redis 6380 (they coexist with Hermes on 8080/5432 and Claudio on 3001).

Local dev (no Docker)

cd src/backend/python-mvp
python3.11 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
export DATABASE_URL=postgresql+psycopg://ai_know:ai_know_dev@localhost:5433/ai_know
export REDIS_URL=redis://localhost:6380/0
alembic upgrade head
uvicorn ai_know.main:app --reload --port 8080

Tests

Unit only (no I/O):

pytest tests/unit -v

Integration (needs docker compose up):

# From inside the running api container:
docker compose exec api python -m pytest tests/integration -v

v0.1 backend RELEASE-READY. See the top-level CHANGELOG.md for landing dates and commits. See ai_know/adapters/hermes.py for the client-side SDK that lets hermes-agent (and any other host) talk to this backend without reimplementing the wire contract.
