# v0.1.0-alpha.42 17/04/2026

***

**Description**: Settings: env vars now required, no in-code fallbacks.

### Changes

* Refactor `settings.py` to remove all hard-coded fallback defaults — every setting must come from an environment variable (ConfigMap in Kubernetes or GitHub Actions env in CI). `.settings.json` remains a local-dev override mechanism (#2067).
* CI: use valid UUIDs for `DEPLOYMENT_ID` to prevent UUID parse errors.
* Migration: widen `user_log.action` from VARCHAR(19) to VARCHAR(32) to fit `subscription_*` actions.
* Tests: isolate flaky tests from xdist parallel pollution (unique subject / topic names, real `UserRepository` in `ConfigSyncService` tests).
