Prepare to include cluster UID in CONTROLLER_IDENTITY to prevent cross-cluster conflicts#308
Conversation
…ontroller-on-controller fighting
Controllers that previously set ManagerIdentity as "release/namespace" (pre-cluster-UID) or "temporal-worker-controller" (pre-Helm default) would be permanently blocked from managing existing Worker Deployments after upgrading, since shouldClaimManagerIdentity only triggered on empty identity. Now reclaims in both migration cases: - exact match on the old hardcoded default - new identity is a longer slash-prefixed version of the existing one Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
… distinct test identity - defaults.ControllerIdentity is now DeprecatedDefaultControllerIdentity to make clear it exists only for upgrade migration detection, not as a live default - integration tests use a dedicated testControllerIdentity constant so they exercise the normal identity path rather than accidentally triggering the deprecated-identity migration branch Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
SetManagerIdentity with an empty identity clears the ManagerIdentity field on the Worker Deployment, leaving it ownerless. Add an explicit check and return an error rather than making the call. The startup check in main() is the primary enforcement; this is a targeted guard for the one call site where an empty value is actively dangerous.

How was this tested:
Envtest won't test our get ns permissions, so just trusting there (we will test it in CI env because it runs on controller startup)
Any docs updates needed?
