Usage: bin/check

Build and run unit/race/static, smoke, migration, operational and contract checks.
Requires Go 1.26+, PostgreSQL, Python 3.14, uv, and curl.

RESETS data in assignment_harness_native and assignment_harness_django.
Uses ports 18000 and 18001; stop development servers first.
PGHOST, PGPORT, PGUSER and PGPASSWORD configure PostgreSQL connections.
DATABASE_URL does not override the suite's fixed database names.
Installs locked Python dependencies and writes diagnostics under .artifacts/.
TMPDIR defaults to ~/codex-tmp.

Example:
  bin/check

Options:
  -h, --help    Show this help without performing work.
