v1 failed wait_healthy 'not healthy / (last status 500)': plausible's app starts before clickhouse
(plausible_events_db) is ready (recipe depends_on names events_db, mismatched → no swarm ordering) and
returns 500 until DB migrations finish (several min on cold deploy). It serves 302 once ready; widen
the health window.

tests/plausible/recipe_meta.py + tests/plausible/functional/test_health_check.py drafted with
EXTRA_ENV setting required Phoenix vars (DISABLE_AUTH, DISABLE_REGISTRATION, SECRET_KEY_BASE).
Stack converges 1/1 but the served app returns HTTP 500 from / for the full 600s HTTP_TIMEOUT
window — config-class failure, not a deploy-timing issue. Diagnosing needs live container-log
inspection + iterative env tuning, more debug cycles than fit autonomous mode. Committing the
draft + a DEFERRED.md entry; operator can iterate when they want.
