Covers the copy-then-delete-later workflow: a user copies books to a new
library, deletes the originals, and ends up with an active copy in the new
library plus an archived twin holding the real reading history. Until now
those twins could only be purged (destroying the history) or restored
(showing a permanently broken entry).
- POST /api/media-items/:id/merge (admin only, body {target_id}):
validates the source is archived/missing, the target is active, and
both share the same file_sha256; then re-parents every child row onto
the target via the existing reparent_media_item_children function (the
same machinery as hash-conflict resolution) and deletes the source row.
Per-user collisions keep the active copy's data, mirroring that flow.
Affected data: reading progress, speed, ratings, highlights, notes,
bookmarks (including tombstoned deleted-annotation history), formats,
collections, kobo shelves/entitlements, sync rows, panel data,
processing issues, and device aliases.
- GET /admin/archived: ListHiddenMediaItems' match_* columns surface each
row's best active twin; rows with a twin get a confirm-guarded "Merge"
button (data-merge-source/-target) next to Restore/Delete, wired in
web/src/admin.ts like the existing unarchive/delete handlers.
- templates.ArchivedItem gains MatchID/MatchTitle/MatchLibraryName;
frontend.go populates them from the listing row.
After a merge the archived row is gone, so the retention purge can never
destroy the merged data. Deleted-annotation tombstones carry over and
remain restorable from the target book's "recently deleted" history.
Admins need to see what the archive lifecycle is holding: a dedicated
/admin/archived page listing every hidden item (archived or still in
the missing grace window) with library, file path, status, and - when
retention is enabled - the exact date it will be permanently deleted
(archived_at + ARCHIVE_RETENTION_DAYS).
Per row: Restore (POST /api/media-items/:id/unarchive, clears the
archive state so it reappears; if the file is still gone the next scan
hides it again) and Delete (existing DELETE endpoint for single-row
purge with its reading history). Purge All Archived reuses the existing
bulk button. The library admin banner links to the page and keeps its
purge button; row actions use data attributes with delegated listeners
in admin.ts since this templ version has no JSFunctionCall helper.
Verified live: page 200 with purge dates shown, unarchive returned 204
and reset the row, per-item delete and bulk purge ({purged:1}) both
removed their rows with no leftovers.
