# `up` starts Postgres, applies migrations, then launches the coordinator.

# Also drops the database volume — use when the schema is beyond repair.
down-clean:

psql:

# --- api ------------------------------------------------------------------
# Exercises every endpoint against a running coordinator; exits non-zero on the
# first unexpected status. See also api/requests.http for clicking through them
