A SecurityPolicy CR could get stuck in Terminating when two or more CRs shared the same spec.policyName and thus resolved to the same Central policyId. Once the first CR's deletion removed the underlying policy from Central (and the cache), deleting the remaining CR hit a nil entry in policyObjectCache. The source guard in DeletePolicy then misfired on the nil policy and returned "policy \"\" is not externally managed", so the controller never cleared the finalizer. Deletion is now idempotent: a policy absent from the cache no longer exists in Central (the desired end state), so DeletePolicy returns success and the finalizer clears. Added a regression test covering the already-deleted case. Note: this fixes the blocking symptom; it does not add duplicate-policyName validation across CRs, which is a larger separate change. Partially generated by AI (Claude Code).
Root-cause fix layered on top of the idempotent-delete change. The controller resolved existing policies purely by name (GetPolicy(name)), so a second CR reusing another CR's spec.policyName would adopt the same Central policyId. That turned what Central would reject as a duplicate POST into a silent PUT that overwrote the first CR's policy, and later left the losing CR unable to delete. Reconcile now enforces policyName uniqueness across CRs: the oldest CR (ties broken by UID) keeps the name while any other CR is rejected with PolicyValidated /AcceptedByCentral = False and its status.policyId cleared, so a rejected CR can never delete a policy it does not own. Rejected CRs are requeued so they reclaim the name once the winner is removed. CRs being deleted are ignored by the check. Chose a controller-side check (vs an admission webhook) for consistency with the existing isDefault collision handling and because no validating webhook is wired up for this CRD; cross-CR uniqueness is also race-prone in admission. Added table-driven unit tests for the collision resolution using a fake client. Partially generated by AI (Claude Code).

Check ownership before deleting a previously accepted duplicate.
The deletion branch runs before findConflictingSeniorCR. If two CRs already record the same Central policy ID, deleting the junior CR before it reaches this new check calls DeletePolicy and can remove the senior CR’s policy. Check duplicate ownership on the deletion path before deleting a recorded ID. As per path instructions, “Focus on major issues impacting performance, readability, maintainability and security. Avoid nitpicks and avoid verbosity.”

Preserve ownership of a distinct policy during a rejected rename.
If an accepted CR changes spec.policyName to a name owned by a senior CR, its original Central policy remains under the old name. Clearing PolicyId and marking the CR unaccepted makes a later deletion skip that original policy, leaving it active without an owning CR. Distinguish a shared policy ID from the CR’s own policy ID before clearing ownership.

Keep the senior CR authoritative until its Central deletion finishes.
A deletion timestamp does not mean the senior CR’s Central policy has been deleted. While its finalizer is still pending, this check lets the junior CR adopt and update that policy; the senior CR can then delete the same ID. The junior CR retains an accepted status for a policy that no longer exists. Wait until the senior CR has completed deletion before allowing the junior CR to claim the name. As per path instructions, “Focus on major issues impacting performance, readability, maintainability and security. Avoid nitpicks and avoid verbosity.”

Description
A
SecurityPolicyCR could get stuck inTerminatingforever, and itspolicyNamecould not be reused, when two CRs shared the samespec.policyName(ROX-37350).Root cause. The controller resolves existing policies purely by name (
GetPolicy(name)inpolicy_controller.go). A second CR reusing another CR'sspec.policyNametherefore adopted the first CR's CentralpolicyId, which flipped the write from a POST to a PUT. Central only enforces name-uniqueness on POST (AddPolicy), not PUT (UpdatePolicyis by ID), so the duplicate silently overwrote the first CR's policy and recorded the shared id. Once either CR's deletion removed the underlying policy, the other CR's finalizer could never complete.This PR fixes it in two layers (two commits):
Reject duplicate
policyNameacross CRs (the real fix). Reconcile now enforces uniqueness: the oldest CR (ties broken by UID, for a deterministic winner under concurrent applies) keeps the name; any other CR is rejected withPolicyValidated/AcceptedByCentral = Falseand itsstatus.policyIdcleared, so a rejected CR can never delete a policy it does not own. Rejected CRs are requeued so they can reclaim the name once the winner is removed. This mirrors the existingisDefaultcollision handling already in the reconciler.Make policy deletion idempotent (defense-in-depth). A finalizer should never wedge permanently because the Central policy is already gone (for any reason).
DeletePolicynow treats a policy absent from the cache as an already-completed delete, letting the finalizer clear.Considered alternatives
