- Field registry (services/filter_registry.go): ~55 typed fields —
every book column, file/lifecycle facts, the three HOLDING
STRUCTURES (library, collections with excluded-aware membership,
series with FULL primary+alternate_info membership), and the whole
user-relative class (status, progress, last read, my rating, review,
notes/highlights presence, note/highlight text, time spent, pages
read, collections, added by) reading the VIEWER's rows. Operators
are typed constants; negation is an operator.
- Composed engines (services/filter_query.go): one Go clause builder
over raw pgx feeds the search (identical SearchMediaItemsUnifiedRow
shape), the field-aware suggestions, and a true-COUNT live count.
Mandatory WHERE head everywhere (family lens + integrity facts).
Values are always bound parameters — no user string reaches a
field/operator position, ever.
- Wire: the qf JSON param (validated strictly — unknown
fields/operators/malformed values are 400); qf wins over flat params
on hand-crafted URLs; flat deep links keep working unchanged.
- Endpoints: GET /api/media-items/filter-count (live count);
field-values autocomplete upgraded in place — any registry field
key, qf binds the OTHER rules (symmetric under-filter suggestions,
zero-match values never offered); classic six without a tree keep
their static pinned contract.
- UI: the drawer becomes the rule builder — the ONLY filter UI (templ
markup, Alpine tree state, sanctioned island; grouped field menus,
operator menus with red negations, field-aware value menus, live
count, chips per rule with red negations, URL rehydration, smart
serialization flat-when-simple else qf).
- Tests: composed semantics (AND/OR/negation/nesting/enums/bools/
numbers/dates/empty), every user-relative field class with the
my-data weld (two readers, different worlds), note-text substring
pin (catharsis ≠ Carthage), family lens (hidden libraries nowhere,
403s), suggestion-under-rules exactness, qf validation + precedence,
flat-vs-tree equivalence; registry completeness unit test.
