The harness default base (recipe_versions[-2]) resolves to 3.0.0+v2.0.0 for
the open 3.1.0 upgrade PR. That release predates x86_64 support in the
clickhouse entrypoint (added 3.0.1): on this amd64 host it downloads
clickhouse-backup-linux-x86_64.tar.gz — a deterministic HTTP 404 — and with
set -e + a silenced wget the container exits 1 before logging anything,
crash-looping until the deploy times out. The base therefore can never
converge, regardless of the PR content (the published tag is immutable).
This is exactly the case the harness documents for UPGRADE_BASE_VERSION:
a PR adding its version ABOVE the newest published tag, where the true
predecessor is [-1] (3.0.1+v2.0.0), not [-2]. The upgrade tier then tests
the real operator path 3.0.1 -> 3.1.0.
Pairs with recipe-maintainers/plausible#3 (its !testme can only go green
once this lands).
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.
