The verify step ran 0.09s after `docker compose up -d --force-recreate`,
well before the container's 30s start_period elapsed — so 'healthy'
isn't yet in docker ps's Status string and the grep failed. False
negative; container was operationally up (verify 1/2 already confirmed
/health 200).
Greping for '^Up' instead catches the case verify 2/2 actually wants
to catch (container exited entirely) without racing the healthcheck.
