Report success when Kobo rejects a delete for a tag it no longer has, so the device stops retrying
one it can never complete. Skip the full-library reconcile while a device is still draining pages,
and page fifty books at a time so a large re-announce costs a few round trips instead of hundreds.
Ref #1005
Embedding metadata rewrites the book file, so its hash moves even though the book itself is
unchanged. Kobo reconcile reads a moved hash as new content and re-delivers the book as a
NewEntitlement, which makes the device rebuild its local entry and orphan every annotation
attached to the old one.
Carry the post-write hash into the device snapshots that recorded the pre-write hash, so
reconcile stays on the metadata-only path. The device keeps the bytes it already has and never
receives the rewritten file; a content change from any other source still triggers a download.
Ref #925
Project manual book status changes onto Kobo reading states and mark device snapshot rows as unsynced. This ensures manual status updates made in the web UI reach registered Kobo devices on the next sync without overwriting device bookmarks.
Closes#812
Exclude the originating device from reading-state fan-out and ignore stale or identical state echoes so paginated syncs can advance. Preserve pending new entitlements while propagating genuine changes to other devices.
Closes#654
Migrate the snapshot and snapshot books tables to be per-device instead
of per-user. This resolves a sync race condition where only the first
registered Kobo device for a user receives the library delta, leaving the
others empty.
Closes#314
