fix(ci): retry a reconcile this deploy's own control-plane restart cancelled - #3479
Conversation
…ncelled A change to the Flux control plane restarts source-controller and kustomize-controller — the two components the deploy's reconcile runs through. source-controller returns before its artifact is rebuilt, so every Kustomization transiently reports ArtifactFailed, and terminating kustomize-controller cancels the in-flight health checks. The single-shot reconcile then failed over a cluster that converged correctly moments later: platform#3459's merge-queue deploy failed in 40s while every Kustomization reached Ready shortly afterwards. Route the deploy composite through a wrapper that grants exactly one further attempt, and only on positive evidence that this deploy restarted the control plane (a Deployment generation that advanced across the reconcile), after waiting that rollout out. A reconcile that succeeds is never retried, and a failure with no control-plane restart still fails on the first attempt, so the deploy continues to require a successful reconcile in every case. The two existing tests that anchored on the deploy composite's bare reconcile line move to the wrapper; the DR workflow still calls the bare command and its anchors are unchanged.

Reading the control-plane generations must not add a failure mode the deploy did not have before. Under `set -e` an unreadable snapshot aborted the wrapper before the reconcile ran at all, so a transient kubectl error would have failed a deploy that previously succeeded. Tolerate an unreadable snapshot and fail closed onto the original behaviour: the reconcile still runs, and without two readable snapshots there is no restart evidence, so no retry is granted. The added case isolates the asymmetric shape — first snapshot readable, second not — because two empty snapshots compare equal and are already caught by the equality check. Ablating the emptiness guard leaves that case the only failure, confirming it is load-bearing rather than vacuous. Part of #3478 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
TestDeployActionClusterLifecycleUsesSOPSAuthButPublishKeepsActionsToken anchors the deploy composite's reconcile section by its run line, which this branch rewired to the wrapper. The assertion it guards is unchanged — that the reconcile step carries no GHCR_TOKEN while publish keeps the Actions token — so only the anchor moves. The DR workflow and the DR runbook still invoke the bare command, and both of those anchors are deliberately left alone.

Grouping the two kubectl queries and piping the group reported only the pipeline's status, so a failed labelled query was masked by a successful flux-operator query. The snapshot then came back non-empty but partial, which compares unequal to a complete one and buys a retry no restart evidence supports — and it slipped past the emptiness guard that was supposed to make the unreadable case fail closed. Each query is now captured and checked separately, and both bound their read: kubectl's --request-timeout defaults to 0, meaning wait forever, and these snapshots run exactly when this deploy may be restarting the API server's clients, so an unbounded read would hang the deploy instead of failing it. The new partial-snapshot case fails against the previous script with "a partial second snapshot must not buy a free retry" and passes with this one; both timeout assertions were ablated individually and each fired.

Flux can observe the newly published revision before the reconcile step runs, so a control-plane rollout may already have advanced the generation by the time the wrapper takes its own "before" snapshot. Both snapshots then match, and the cancellation this deploy inflicted on itself is reported as a genuine failure - the outage the wrapper exists to prevent. Capture the baseline before the mutable tag is published, from the same producer so the comparison stays textual, and fall back to the in-wrapper read when it is unavailable.

Motivation
A deploy that changes the Flux control plane fails over a cluster that is actually fine.
Changing the Flux controllers restarts them — and they are the same components the deploy's own readiness check runs through. The check sees them mid-restart, calls the deploy a failure, and the merge queue evicts the PR. The cluster converges correctly a minute later.
This happened to #3459 this morning: the deploy failed in 40 seconds, the change was reverted, and every Kustomization was healthy shortly afterwards. It is structural rather than flaky, so retrying the same PR reproduces it — which makes control-plane changes effectively unlandable through the normal gate, and those are exactly the changes that carry the cluster's hardening work.
What
The deploy now reconciles through a wrapper that allows one extra attempt, and only when it can show that this deploy restarted the control plane.
The deploy still requires a successful reconcile in every case; what changes is that a failure the deploy inflicted on itself is no longer reported as a workload failure.
Both directions are pinned by tests, including the negative one — a genuine failure must still fail. The disaster-recovery path is deliberately untouched.
Fixes #3478
