Pull request overview
This PR hardens catalogd catalog serving by verifying that catalog.jsonl is present and readable on disk (and forcing an fsync) before the ClusterCatalog status is updated to Serving, reducing the risk of advertising a serving URL before content is actually available.
Changes:
- Extended the
storage.Instanceinterface withVerifyAndSync(catalog string) error. - Implemented
VerifyAndSyncforLocalDirV1to stat/open/fsync and minimally readcatalog.jsonl. - Updated the
ClusterCatalogreconciler to callVerifyAndSyncafterStore()and before settingServing, plus updated mocks/tests accordingly.

Persist the rollback removal after GraphQL validation fails.
When GetSchema fails, os.RemoveAll(catalogDir) removes the catalog after the earlier syncDir(s.RootDir) persists the rename. The branch returns without synchronizing s.RootDir again. The deferred staging-directory cleanup and orphan cleanup do not sync the root directory. A crash can therefore leave the removed catalog directory recoverable. Call syncDir(s.RootDir) after a successful rollback removal and report any synchronization error.
