# Application Notes ## API The API lives in `apps/api/src/ecospecies_api` and supports two storage modes: - PostgreSQL through Docker Compose - SQLite fallback for host-local verification The importer writes persisted `species`, `document_section`, and `ingest_diagnostic` records before the API serves traffic. ## Web The web app is static and served by nginx. nginx proxies `/api/*` and `/healthz` to the API service inside the Compose network. ## Dependency handling Compose bootstraps a bind-mounted Python virtual environment in `.docker/venv` and installs `apps/api/requirements.txt` into that environment. This keeps runtime dependencies isolated from the host Python installation while leaving the environment visible on the host filesystem.
