The re-review of the fix round surfaced 4 findings; fixing the coverage one
exposed that the C1 migration was ineffective:
- FeedFiltersProvider.loadAccountFilters: run coerceTagModes on the RAW stored
blob, not the object merged over DEFAULT_FILTERS. The merge injects
DEFAULT_TAG_MODES (all "or"), which coerceTagModes prefers over the legacy
scalar `tagMode` — so the migration never fired. Now a persisted legacy
tagMode:'and' actually migrates into tagModes.topic (proven by a new test).
- test_feed_views: the tag_mode_other=and case was vacuous (only chC carried
either "other" tag, so AND == OR). Give chA an "other" tag too so OR-other
{chA,chC} differs from AND-other {chC} — the conjunctive path now narrows.
- DateFilterSelect: reset the custom reveal in useLayoutEffect (not useEffect)
so the correction commits before paint — no one-frame "Custom range" flicker
on the trigger after an external clear.
- SavedViewsProvider: extract the sticky-view tie-break to a pure, tested
lib/savedViews.ts (preferSticky).
New tests: savedViews (preferSticky), FeedFiltersProvider.dom (legacy tagMode
migration on the localStorage/default-view seed).
