- Rename EngagementEvent.metadata → event_metadata (SQLAlchemy reserved name) - Replace passlib with direct bcrypt usage (passlib incompatible with bcrypt 5.0) - Fix renderer Dockerfile: npm ci → npm install (no lockfile) - Fix frontend Dockerfile: single-stage, skip tsc for builds - Remove deprecated 'version' key from docker-compose.yml - Add docker-compose.dev.yml for data-stores-only local dev - Add start_period to API healthcheck for startup grace
