RCP-WP-0002 T02-T04 done, readiness_state verified with evidence attached
rather than ahead of it.
rapp-postgres provisioned canned_prompts on platform-pg-2 and sent a
database-owner receipt with 12 checks proven live. creds/canned-prompts-publish
was deliberately not issued, so the service runs read-only and POST /packages
returns 503 explaining why — the intended posture, not a gap.
Four defects surfaced that only a real rollout could expose, two of them
silent:
- SET ROLE opened an implicit transaction that Alembic nested inside rather
than owning, so every revision logged as applied and was rolled back.
Alembic reported success against an empty database.
- The egress NetworkPolicy selected app.kubernetes.io/name, which the
migration Job does not carry. The Job matched only the default-deny and
succeeded exactly once, because it ran before the policies existed; the next
migration would have failed on DNS. Now selects part-of, with ingress split
into its own policy so the Job is never reachable.
- env.py read database_url rather than resolved_database_url, so the migration
could never run where the credential is a mounted file.
- live-image-digest-match extracted the pin with a line-offset grep, which
returned empty once comments were added above `version:`. The check degraded
to reporting "not pinned yet" while a digest was pinned — it could not have
passed for any pin. Now parsed as YAML. A verification step that cannot fail
is worth less than none, because it is trusted.
