Phase 1 + backend of Phase 2 of the faceted-navigation plan. One
declarative facet registry (services/facet_registry.go) drives the
bookshelf filter system; a drift-guard unit test reflects over the
generated SearchMediaItemsUnifiedParams so a registry entry and its
sqlc.narg block can never disagree silently.
- Nine new filter params on SearchMediaItemsUnified: story_arc,
imprint, edition (scalar-fuzzy), age_rating, format_group,
manga_type, reading_direction (exact), explicit, abridged
(presence-bound bools). Comma = OR-within multi-select on every
text facet; AND-across-facets unchanged.
- Genre model v2 (user rule: a subgenre is not a genre, it's a tag):
genre_lexicon.go rebuilt as shelf set + subgenre->shelf map;
pickSmartGenre picks direct shelf > mapped subgenre > Fiction floor
> empty (unknown-only stays tags-only). Type-words (Manga, Comics,
Graphic Novel) join the demote list. Both 'adventure' and 'action &
adventure' are shelves — provider data uses both and the verified
traces pin them.
- Language filter UX: comma elements normalize through the ingest
language map, so display names ('English') match rows stored as ISO
codes ('en'). The language autocomplete now serves display names.
- NEW GET /api/media-items/facets?facet=X&library_id=... — registry-
driven value+count listing (14 static per-column queries, family-lens
join); language values carry display names; bool/range facets 400.
- Family-lens gates: an explicit hidden-library library_id is now a
403 on the search endpoints (was a silent empty set) — JSON branch
and HTMX grid partial both.
- handlers.ParseMediaSearchParams is the SINGLE param parser for the
search JSON endpoint and the HTMX grid partial; the HTML branch
previously dropped publisher_filter and narrator_filter silently.
Pins: docs/contract_pins.md changelog entries (additive request
params; new facets endpoint). Tests: facet_registry_test.go (shape +
SQL drift guard + library-type union), series_parsing_test.go genre-v2
cases, facets_integration_test.go (param filtering e2e, counts,
language display, 403s) — container runner.
