A firm on a platform the build didn't know was skipped, yet the cache was
stamped current, so after updating to a build that knows the platform the
sync sent ?since= and the master answered "unchanged": the firm (Vest, on
machines that synced before 96fdd9c) stayed missing until an unrelated
catalog edit. The parser version goes to 3, so those caches fetch in full
once, and a payload now names the platforms it skipped (skippedPlatforms):
a cache whose skipped platform this build knows is no longer current. Kept
rule ids still report from such a cache. scripts/check-catalog.mjs syncs
against a stand-in master on a local port.
