Chair-approved (Claude Design card 09): split the flat table into collapsible
sections by where the gap surfaced, so the high-value "cited by Dafna" rulings
aren't buried among the 330 digest rows.
- Three <details> accordion sections within the active status tab:
· "צוטט ע״י דפנה" — rows with a resolved chair from the citation-graph bridge
(cited_by_chairs non-empty); open by default.
· "יומון" — discovery_source='digest'; collapsed.
· "אחר" — party-cited / manual remainder; collapsed.
- Row JSX extracted to renderRow() and reused across sections; shared
TableHeaderRow(); grouping via useMemo over the current result set.
- Empty sections are hidden; section header shows source chip + count.
No backend change — groups on existing cited_by_chairs / discovery_source.
tsc --noEmit clean.
Invariants: INV-IA* (task-oriented surface, single gate) — UI only.
