v1.26.0 (2026-10-02)

The parity audit's fix wave: every confirmed bug and divergence lands

The 2026-10-02 eight-agent parity audit (four reviewers, two bug hunters,
one compat-merge review, one claim verification -- 8/8 top claims confirmed)
found three shipped-code bugs, eleven confirmed divergences, and a gaps
list. This release fixes the bugs and the divergences users plausibly hit,
and records the rest in the roadmap's audit block.

• set_book_storage stores upstream's bare data map (was the wrapped
  {'timestamp', 'data'} entry, which Calibre's validating reader dropped
  on every cquarry-written row), with upstream's guards reproduced
  (str-only keys/values, the 1 MiB UTF-16 cap, newest-timestamp-wins) and
  the missing read half shipping as get_book_storage.
• remove_book cleans books_pages_link and book_storage -- the two
  FK-cascade tables neither books_delete_trg nor cquarry's
  foreign-keys-off connection covered; the stranded pages row (its book
  column is the PRIMARY KEY) broke move_book_from_trash with
  IntegrityError on any library with page counts.
• get_categories follows upstream's is_category = normalized rule
  (direct-storage customs out -- their raw values made engine-unparseable
  expressions), gains the identifiers category (one node per identifier
  key), and escapes expression values for quotes/backslashes.
• Search parity, claim-verified: bare-term sweeps match identifier
  KEYS like upstream (the 1.18-1.25 spec sentence said otherwise and was
  wrong about upstream); all:false is upstream's sequential loop
  (missing AT LEAST ONE swept field, not missing every); cover: is
  numeric with exactly true/false special-cased (cover:1 works,
  cover:yes raises).
• New author rows follow upstream's creation path: the name stores
  with commas as the legacy pipe and the sort is
  helpers.author_to_author_sort's flip under the default tweaks -- the
  old verbatim defaults rested on a spec sentence that was factually
  wrong about upstream.
• Writer fidelity: remove_format queues the pages rescan;
  set_plugin_data json.dumps's every payload (the str-verbatim
  shortcut stored strings upstream's reader cannot decode);
  set_conversion_options wraps payloads in upstream's deterministic
  protocol-2 frame (fresh rows were unreadable by Calibre's unpickling
  reader); set_custom_series_index writes the link row's extra float
  and fresh series assignments seed it at 1.0;
  set_author_sort_name gains update_books=False and its long-promised
  honest no-op; copy_book_from_library carries a 0.0 series index
  verbatim and its author-sort postprocess no longer rewrites existing
  destination books.
• Recorded, not adopted (roadmap audit block): the enum count-operator
  gap, negative Ndaysago, loc:="X"'s contains-vs-exact degradation,
  translated date vocabulary, the search-behavior prefs, upstream's
  localized language node names, ICU sort keys, and the popularity/
  first-letter sort parameters -- each dependency-bound or GUI-state-
  bound, now named in spec §5 or the roadmap.
• Housekeeping: the compat branch carries the merge-review erratum
  (restored its own 1.18.0+py313.1 entry; suite count corrected to 653).
• Suite: 672 tests (flat -- every fix reshaped existing pins rather than adding volume; the new pins replaced the wrong-shape ones one-for-one).
