Why

PR #3818 removed OpenCost from the desired manifests, but production correctly retained its prune-protected release and namespace. OpenCost is therefore still running and the convergence is incomplete.

What

Add a default-off, protected production action that safely removes only the orphaned OpenCost installation and independently verifies it is gone. Merge-group and recovery deploys cannot activate the deletion.

Operational gate: after this merges, dispatch CD from main with retire-opencost enabled; then remove the one-shot tooling.

Part of #3810

Readiness evidence

• Exact PR head: 40ff4f42d504f37f0ded8b9d54c8162faa5f0aef; live main at closing rebind: 29ba6bc970beabe1a129919e83cc328e058167d8; GitHub reports the PR mergeable and clean.
• TDD: the new missing-inventory case failed before the implementation change, then passed after the script began requiring .status.inventory.entries to be an array before interpreting absence as orphan proof.
• Local behavior: retirement, wiring, aggregate Coroot convergence, prune-protected orphan alert, PVC-prune safety, ShellCheck, actionlint, and production-authorization unit checks pass.
• CI: 29/29 checks are terminal with no failures (23 success, 6 expected skips).
• Review: Codex completed an exact-head review on 40ff4f4 with no findings and no unresolved threads. CodeRabbit was explicitly unavailable under its recorded rate-limit window, so the configured fallback reviewer was used.
• User evaluation: the fake-cluster acceptance test proves HelmRelease-before-Namespace ordering, current-main binding, default-off behavior, PVC/ownership/inventory refusal, cleanup verification, and no destructive command on every refusal path. The real production deletion remains deliberately gated to a manual main CD dispatch after merge.

Ready for the merge queue.
