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.

Root cause: Ghost's fresh-DB first boot runs a ~6-9min schema migration (round-trip-bound, not CPU);
the recipe healthcheck start_period:1m (~6min grace) kills the still-migrating task, leaving a stale
migrations_lock → every later task deadlocks (MigrationsAreLockedError). Hit on both 2- and 4-vCPU.
Fix (cc-ci deploy overlay, NOT a recipe/test change): compose.ccci-health.yml raises app healthcheck
start_period to 900s, wired via recipe_meta COMPOSE_FILE + install_steps.sh (+ CHAOS_BASE_DEPLOY for
the untracked overlay). No assertion weakened. Budget 1200s = migration + convergence. Only the
install tier needs it (upgrade redeploys on the populated DB → fast boot).
