gallery_downloads.configured was true on every installation with a gallery. allow_downloads ships true — column default in migration 037 and the create route both set it — and the snapshot asked "at least one gallery has it on". The fleet value was ~100% by construction and could not separate a deliberate configuration from an untouched one. v2 consented to that key under that description, so v2 keeps sending it unchanged. v3 replaces it with gallery_downloads_restricted: at least one gallery has downloads switched off, which is the only state of that column anyone actually decides. Same catalog position, so the disclosed capability count stays at 86; the frontend copy, the EN/DE catalog strings, the coverage inventory and FEATURE_COVERAGE.md follow. Done in v3 rather than a v4 because v3 is on main and in no release yet, so nobody has consented to it. The collector carries the same catalog and has to take this change before the release that ships v3. One guard for the window in which :main / :beta images already carried the old v3 catalog. A report queued under it fails local validation on this build, and deliver() left a locally invalid report pending for good, blocking every operation behind it. A report's payload is derived state, so deliver() now rebuilds it from the current snapshot in place and sends that. Packet ID and sequence are kept — a re-signed retry has to reuse them so a lost acknowledgement does not duplicate data — and reports only: a stale registration, deletion or command is a genuine conflict and keeps the existing handling. Tests: the v3 snapshot counts a switched-off gallery and ignores enabled ones, v2 still reports the old key with the old meaning, and a stale queued report goes out rebuilt under the same packet id while a valid one is sent untouched.
