precedent_internal_citations resolves cited_case_law_id only at extraction
time. When a decision cites a ruling that isn't in the corpus yet, the edge is
stored with cited_case_law_id=NULL. The ruling is often uploaded days later —
but the orphan edge was never re-resolved, so the citation graph permanently
under-counted real connectivity (same stale-derived-value pattern as the
searchable flag). Worse, external rulings store case_number WITHOUT the court
prefix ("3213/97") while citations carry it ("ע\"א 3213/97"), so a large share
of "missing" citations were actually present-but-unlinked.
Fix:
- new citation_extractor.relink_orphan_citations(case_law_id=None): re-resolves
orphan edges via the canonical _resolve_case_law_id (no parallel matching, G2);
scoped to one row, or full sweep when None. Idempotent.
- ingest_document calls it on every upload (non-fatal) so the graph self-heals.
Existing backlog already re-linked via a one-off sweep against the live DB:
linked 128 edges → in-corpus distinct rulings 67→178, unlinked distinct
262→143. So real "cited but not uploaded" ≈ 143, not the 262 the stale graph
implied.
Invariants: G1 (re-resolve the derived link at the write) · G2 (single resolver).
