Per Adversary course-correction (bdef282) + plan-ccci-compose-overlay-policy.md §1: upgrade-to-latest
is MANDATORY. The 0.7.0+3.3.1 from-version pins the Docker-Hub-removed bitnami/discourse:3.3.1 (404)
and ships a too-tight 5m start_period for the 15-25min Rails cold boot. Minimal base overlay
compose.ccci.yml re-pins app+sidekiq to bitnamilegacy/discourse:3.3.1 (namespace-only, identical
image — same re-pin the PR head makes) + widens start_period to 20m (grace-only). install_steps.sh
provides it; CHAOS_BASE_DEPLOY skips the clean-tree gate; UPGRADE_BASE_VERSION=0.7.0+3.3.1 sets the
true predecessor. Neither change weakens a test. Run shape returns to STAGES=install,upgrade,backup,
restore,custom.
