The AutoscalingRunnerSet controller detected changes by hashing the spec and the labels on every reconcile and comparing the result against the actions.github.com/integrity-hash annotation it had written on a previous pass. That is a hand-rolled version of something the API server already does for us: it bumps metadata.generation on every spec write, and nothing else. Recording that value in the status as ObservedGeneration gives the same "has this changed since I last applied it" signal without recomputing a hash, without an extra non-status write to the object, and with a value a user can read and reason about. updateStatus now takes the observed generation and patches it next to the phase, returning early only when both are already what we want. When the generation is ahead of the observed generation we move to Pending but deliberately leave the observed generation where it is; it only catches up at the end of a reconcile that actually applied the change, so a reconcile that fails part way through is retried as pending rather than being mistaken for settled. The old code returned immediately after stamping the hash. That was needed because stamping the annotation was itself a write to the object, so continuing would have worked from a stale copy. Recording the generation only touches the status subresource, which does not bump generation, so the rest of the reconcile can run on the same object and apply the change in the same pass instead of waiting for the next event. One user-visible difference: the old hash covered Labels as well as Spec, and metadata.generation does not move when only labels change. Editing just a label on an AutoscalingRunnerSet no longer forces it through Pending. Labels still propagate to the EphemeralRunnerSet; they simply no longer count as an update that has to be applied. Hash, ListenerSpecHash and RunnerSetSpecHash are removed. The latter two already had no callers, and the first has none now. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
