Enables the previously-disabled "הלכות" toggle. Each approved/published halacha
of a displayed precedent becomes a hal:<id> node linked to its parent
precedent (extracted_from); two cross-rule edges when both endpoints are in
view: corroborates (a later ruling cites the rule —
halacha_citation_corroboration) and equivalent (same principle from another
committee — equivalent_halachot). Node size = corroboration in-degree.
Backend (web/graph_api.py — read-only, G2):
- _halacha_nodes_and_edges(): halachot WHERE case_law_id in view AND
review_status IN (approved, published), LIMIT 600; rule_type carried in the
source_kind slot, rule_statement in note. Wired into both build functions
(gated via node_types). Metrics still exclude halacha edges (only cites/
precedent-typed feed PageRank). Validated: 185 halachot on the top-30
precedents; 20 corroboration + 5 equivalent edges in the corpus.
Frontend:
- graph.ts: GraphEdgeType += extracted_from.
- graph-filter-panel: "הלכות" toggle enabled (was disabled "שלב ב׳").
- graph-canvas: amber halacha nodes; edge colours — extracted_from (faint
amber), corroborates (amber), equivalent (violet).
- graph-node-panel: halacha branch — אזכורים + סוג כלל + rule text; "open in
library" deep-links to the parent precedent.
- graph-view: halacha added to node + edge legends.
web-ui build + lint pass. Invariants: G2 (SELECT-only), UI2 (no model change —
reuses note/source_kind/case_law_id slots).
