Own-audit found the first pass had a spec-update race: if a user
edited PackageSource.spec.variants on a running cluster, cozystack
would bump the derived ArtifactGenerator to Generation=2, and
between "source-watcher started reconciling gen=2" and "source-
watcher wrote new Inventory + ObservedSourcesDigest for gen=2" the
ArtifactGenerator still exposes the previous generation's
Inventory / ObservedSourcesDigest AND Ready=Unknown (Progressing).
The workaround would synthesise Ready=True on stale artifacts, and
downstream Flux would consume the previous-generation
ExternalArtifacts as if the new spec had converged.
Tighten the predicate to require the Ready condition's
ObservedGeneration to match ag.Generation. Only when source-watcher
has actually processed the current spec (which happens strictly
after it writes the current-generation Inventory + Digest) does the
Ready condition carry ObservedGeneration == ag.Generation. That is
exactly the window where Inventory / Digest are guaranteed current-
spec AND only the status patch on Ready itself failed — the actual
upstream bug this workaround exists to paper over.
Consequence: if Ready is missing entirely we return false now
(was true). We cannot verify ObservedGeneration on an absent
condition, and the missing-Ready state is indistinguishable from
mid-reconcile-of-a-newer-generation. On the next reconcile source-
watcher will write at least a Progressing condition, at which point
the current-spec Generation check will be evaluable and the
workaround will kick in if — and only if — Inventory / Digest also
match the current spec.
Tests updated:
* changed 'no Ready condition' case from want=true to want=false
(reflecting the tighter invariant);
* added a case where Ready=Unknown carries an OLD Generation
(want=false — do not synthesise on stale artifacts);
* stamped ObservedGeneration on every existing condition-bearing
case so they exercise the matching-Generation branch;
* introduced a small agWithGen helper to keep the fixtures
readable now that Generation is load-bearing.
All 8 subtests pass; existing operator suite unaffected.
