Nothing blocking. The comments below are optional suggestions. There is no need to push a fix for them before merging.
Beyond the inline findings, I also checked whether the new provider-gates matrix leg could collide with the existing integration leg on the self-hosted runner — both jobs share runs-on: core-e2e but keep KIND_NAME: kube hardcoded, so a same-named kind cluster could clash between the two parallel legs; ruled it out as a real risk here since the PR's own conventions/description treat each matrix leg as running on its own dedicated runner/cluster rather than sharing one host.
Extended reasoning...
Findings were already reported and verified for this PR (leaked temp binary directory, page-1-only sticky comment lookup missing older marker on busy PRs, and a sync.Once that permanently caches a transient build failure). Per the review guidelines, when findings exist and the hunt's exit reason is max_bugs (not dry_streak), approval is off the table and a full defer/summary review is unnecessary noise — the inline comments already signal that human review is warranted. I independently re-checked the workflow diff and confirmed env: KIND_NAME: kube remains a single hardcoded literal shared by both matrix jobs (integration, provider-gates) at the job level, which is the basis of one of the two candidate issues already investigated and ruled out. Since this is a concrete, verifiable point beyond the posted findings, and it was investigated and dismissed as a real problem based on the runner-per-matrix-leg design, I'm recording it briefly per the narrow exception for ruled-out concerns. I did not restate any of the three confirmed inline findings, and I am not approving given the outstanding findings and the non-dry_streak exit reason.

Beyond the inline findings, I also checked whether running the two matrix legs (integration and provider-gates) both on runs-on: core-e2e could cause them to collide on a shared self-hosted runner/cluster resource — each matrix entry gets its own isolated runner job as usual, and the two suites don't share cluster or workspace state, so this is not an issue.
Extended reasoning...
Beyond the two confirmed inline findings (fork PRs never getting the sticky comment due to GITHUB_TOKEN being forced read-only on pull_request-triggered workflows, and Compare() double-reporting a replaced pod as both pod-replaced and deleted), I checked the candidate concern that the new crd-e2e matrix's two legs (integration and provider-gates) both declaring runs-on: core-e2e would cause a runner or cluster conflict. Reviewing the diff, each matrix entry runs as an independent job invocation with its own runner allocation and its own kind cluster setup (the comment in the workflow explicitly notes parallel legs cannot share a live cluster), so this does not reproduce as a real bug and I ruled it out.
Findings marked 🟡 are optional suggestions and need no follow-up push.

Beyond the inline finding, this run also checked two additional angles and ruled them out as non-blocking: the sticky-comment publish job has no concurrency: group, so rapid successive pushes to the same PR could in theory produce two comments instead of one update — a cosmetic risk, not a functional bug; and feature_mock.go's TEE label/RuntimeClass cleanup won't run if go test hits its overall timeout (t.Cleanup never fires on a killed process) — a real but edge-case gap distinct from the already-flagged partial-cleanup issue on ordinary failures.
Extended reasoning...
This run's diff shows two of my previous review's findings were fixed in the latest (squashed) commit: the publish-gates-summary job now explicitly skips fork PRs (github.event.pull_request.head.repo.full_name == github.repository) to avoid the guaranteed 403 from a read-only fork token, and the sticky-comment lookup now uses gh api --paginate instead of a single per_page=100 page, fixing the duplicate-comment-on-long-PR risk. observer.go's Compare() second loop was also corrected to only report "deleted" when a pod name is entirely absent from the current set (not merely present under a new UID), fixing the double-report issue I raised previously. A new CONFIRMED finding (feature_mock.go:103) is being posted inline for this run: a mid-loop node-label-patch or RuntimeClass-create failure leaves already-applied mock labels unreverted since t.Cleanup registers only after the loops complete. Since a findings-present situation exists, per the review protocol I am not approving; I'm posting only a brief informational note about two additional angles examined and ruled out this run, which were not previously communicated.

Beyond the inline finding, this run also looked at two other candidate issues and ruled them out: a transient failure to open the namespace event watch in observer.go doesn't fail the gate, since Compare's end-of-window List/diff (not the watch) is documented and implemented as the authoritative disruption check; and the integration/provider-gates matrix legs sharing the job-level KIND_NAME: kube is intentional and isolated — each matrix entry runs as its own job/runner per the workflow's own comment ("each suite runs ... on its own runner and kind cluster, in parallel"), so there's no cross-job cluster-name collision.
Extended reasoning...
This run re-verified two candidate issues raised against the current diff. First, integration/observer.go's Watch() treats the pod watch as hard-failing but the event watch as best-effort; the surrounding doc comments and Compare() implementation confirm the end-of-window List/diff against the baseline is the authoritative disruption verdict, independent of the watch stream, so a transient event-watch-open failure does not cause a false pass/fail of the restart/upgrade gates. Second, integration-tests.yaml's new matrix (integration, provider-gates) both reference the same job-level KIND_NAME: kube env var feeding cluster_name, but the workflow's own comment states each matrix suite runs its shared setup "on its own runner and kind cluster, in parallel," and GitHub Actions matrix jobs are independent job instances (each with its own runner allocation), so a same-string cluster name does not by itself imply a shared physical kind cluster or collision. Given a prior review already exists on this PR and only one new confirmed finding is being posted this run (with one further verified finding intentionally withheld per the dedup/prune policy), this is a narrow informational note per the ruled-out exception, not a full re-review.
This pull request has been reviewed before and this review found new issues. Where they share a root cause, one fix may close them together.

Beyond the inline findings, I also checked the new provider-gates matrix leg for a kind-cluster-name collision with the integration leg (both use runs-on: core-e2e and job-level KIND_NAME=kube) — ruled out, since GitHub Actions dispatches only one job at a time per self-hosted runner, so same-labeled jobs queue rather than run concurrently on the same host and clash on the cluster name.
Extended reasoning...
This run's inline findings (provider_process.go SIGTERM handling and Start() error-check misplacement) already signal that human review is warranted, so no separate approve/defer summary is needed for those. The one additional item worth surfacing is the matrix concurrency question flagged in the ruled-out list: the new strategy.matrix.suite: [integration, provider-gates] on crd-e2e reuses the same job-level KIND_NAME=kube and runs-on: core-e2e for both legs. On inspection this is not an actual collision risk because GitHub Actions self-hosted runners are exclusive per job — a runner matching a label executes one job at a time, so two matrix legs sharing a runner label simply serialize (queueing) rather than executing simultaneously on the same host and fighting over the same kind cluster name. This is worth noting as a ruled-out candidate since it was flagged as a plausible concern in this run's investigation but doesn't hold up under GitHub Actions' runner-dispatch semantics.

Nothing blocking. The comments below are optional suggestions. There is no need to push a fix for them before merging.
Beyond the inline findings, I also checked the provider-restart drain path in restartProvider (integration/e2e_test.go) for a hang risk when a mid-test provider restart's drain stalls — it has an explicit 60s timeout that calls t.Fatal, so a stuck drain fails the test promptly instead of hanging the whole go test binary.
Extended reasoning...
This run's inline findings (a missing concurrency: group causing a stale/duplicate sticky workload-health comment) are already posted separately. Beyond those, I re-checked a candidate concern about restartProvider in integration/e2e_test.go: the worry was that if the previous provider stack's errgroup.Wait() hangs during drain, the whole go-test binary could hang indefinitely on a later restart cycle. Reading the code (integration/e2e_test.go around lines 579-599) shows the drain is wrapped in a select with a time.After(60 * time.Second) branch that calls s.T().Fatal(...) if draining does not complete in time, so the concern does not hold — a stuck drain fails fast with a clear message rather than hanging silently. I also confirmed that two previously-raised concerns near .github/workflows/integration-tests.yaml line 261 (fork-PR read-only token causing 403 on the comment post, and comment pagination beyond 100 comments missing the sticky marker) have both been addressed in the latest commit: the publish step now guards with github.event.pull_request.head.repo.full_name == github.repository to skip fork PRs, and uses gh api --paginate to walk all comment pages before deciding PATCH vs POST. The new confirmed finding in this run (the missing concurrency: group letting two same-PR workflow runs race to update/duplicate the sticky comment) is a legitimate, previously-unraised issue and is left as the inline comment rather than restated here.

Adds an e2e harness that verifies a running tenant workload is not rolled, restarted, or deleted when the provider process restarts or is upgraded across versions. The gates run the real provider against the kind cluster and watch the lease namespace throughout the event: same-version restart, cross-version upgrade (deploy with the PR base version, recover with the candidate), a subprocess smoke, and SNP confidential-compute variants mocked via node labels and kata RuntimeClasses so no TEE hardware is needed. Rebased on main (which carries the recovery fix from #434) and squashed to one commit.
They run as a non-blocking parallel leg of the e2e job and post a workload-health table as a sticky PR comment. Validated red without #434 and green with it on a kind cluster.
