- Rewrite post_list/filter schema (PHP + JS) with the reference theme's
field set, order, defaults and dependencies; topics fields excluded
(no topics taxonomy), AKSRT private filter_* toggles dropped
- Support dynamic checkbox options in AksField (options as formData key)
so cat_custom_filter.custom_filters lists the custom_filter dimensions
- Map PostDisplay filter settings to the new keys without legacy fallback;
cat_custom_filter now carries lists/dropdown fieldsets and array filters
- Wire the archive chain to reference semantics: cat_custom_filter
overrides per-category filter projects, custom_filter_show gates the
default display, dimension chip groups render on category/tag archives
- Filter archive queries (main query + AJAX endpoint) by _aksrt_cf_{key}
meta with exact-quoted LIKE matching
- Add advanced-filter settings reference contract test
