+## M50 — preserve web/API compatibility alias during rollout (2026-08-21)
+
+- The first steady-gateway M49 rollout correctly kept M48 serving when both candidate web
+  containers failed health. Their static Nginx configuration resolves `api` at startup,
+  while the rollout initially published only the revision-specific API alias used by the
+  gateway. The rejection removed every candidate and left the recorded production revision,
+  four old replicas and public readiness unchanged.
+- Added the compatibility `api` alias alongside the revision-specific alias. The stable
+  gateway continues to route `/api` only to the revision-specific upstream, so the generic
+  name cannot weaken atomic promotion; it solely lets the independently usable web image
+  validate its existing proxy configuration.
+- A continuous external probe recorded **500/500** successes throughout the rejected
+  candidate rollout and rollback.
+- Exact next action: validate the compatibility alias in isolation, commit/push M50 and
+  deploy its exact archive while repeating the zero-error steady-gateway probe.
