When the network failed behind the service worker, it answered from its own store. Check for new data then said nothing newer was published when the server was never reached. The worker now marks that copy, and a fresh check treats it as unreachable; ordinary loads still use it offline. The built-in tasks entry linked to a follow-up fix instead of the feature, and the changelog spec's details now match what shipped. Co-Authored-By: Claude Opus 5.5 <[email protected]>
