Course correction (REVIEW-2 bdef282) mandates upgrade-to-latest; harness base-deploys
prev published version 1.1.1+6-alpine which predates the recipe-PR 15m start_period bump
(ships 1m) → would deadlock on the ~6-9min fresh-DB migration (swarm kill mid-migration →
held migrations_lock). Policy-blessed minimal base overlay: compose.ccci.yml re-applies the
15m app-healthcheck start_period grace to the BASE so the from-version is deployable;
install_steps.sh provides it; CHAOS_BASE_DEPLOY skips clean-tree on the untracked overlay;
persists across head checkout (idempotent — PR head ships 15m). Grace-only, no test weakened.
Prior corrupt mysql vol (stale, interrupted init) torn down. Next: full run incl upgrade.
