📝 WalkthroughWalkthroughThe change adds Kyverno fixtures and permissions for stale policy-report pruning. A shell script installs Kyverno, creates stale and current report scenarios, and verifies report recreation and preservation behavior. A GitHub Actions workflow runs the proof on a pinned kind cluster with restricted permissions and the production Kyverno chart version. Priority: ⬇️ Low Merge Risk: ⚪ Minimal · up to The new temporary-cluster proof and CI workflow have no identified merge-blocking issue. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@scripts/prove-kyverno-stale-report-prune.sh`:
- Around line 71-72: Update the scan-wait logic around has_results in the
stale-report pruning script to record both owner-label and team-label result
timestamps, then wait for a completed background scan by requiring owner-label’s
timestamp to advance while team-label’s remains unchanged across the expected
scans before applying the deleting policy. Preserve the existing
result-presence, UID, and recreation assertions.

Learning: When changing behavior in Kubernetes manifests or related documentation, review comments and documentation in YAML/YML and Markdown files for statements describing the previous behavior. Update every stale statement in the same change so the repository’s explanatory text remains consistent with the implementation.

Learning: Repository shell tests and scripts must remain compatible with macOS Bash 3.2. Do not use Bash 4+ features such as `mapfile`; use portable constructs, such as a `while IFS= read -r` loop, instead.

| Run | Head | Result |
|---|---|---|
| 35253485309 | 3f9ab6be |
PASS — defect reproduced (stale result survived 3 scans), DeletingPolicy pruned it, report regenerated with only the current result, control report untouched |
| 35254320662 | 0703572d |
PASS — additionally asserts the report UID changes (deleted, not rewritten) |
| 35256996849 | 7660fdf6 |
PASS — the replacement wait fired in 11 s on a real scan completing; team-label timestamp unchanged, UID changed, control untouched |
That last run is what makes this more than a well-formed manifest: it observes the real Kyverno 1.19.1 behaviour on an ephemeral kind cluster — time.now() and timestamp(int(r.timestamp.seconds)) do work in a DeletingPolicy v1beta1 CEL expression, which was unproven when this PR opened.
Follow-up (not in this PR): the production slice for #2573 — the DeletingPolicy plus a cleanup-controller grant into k8s/, with the threshold in hours rather than minutes, and an in-PR fingerprint re-approval.
Why
Kyverno leaves a result behind when a policy stops matching a resource, so the policy reports show failures that no longer apply. The planned fix deletes reports that hold such leftovers. Whether it behaves safely can only be seen on a running cluster, and production should not be where that is first seen.
What
Adds a small workflow that builds a throwaway cluster, installs the Kyverno version production runs, and reproduces the leftover result. It then applies the cleanup policy and checks that the leftover is removed, that the report comes back with only current results, and that a report with only current results is left alone. Nothing reaches production yet; the policy and its permission ship in a follow-up once this passes.
