New self-contained table + MCP tools + FastAPI endpoints for letting
the chair attach external case-law quotes (quote + citation מראה מקום,
optional chair note, optional archived PDF) to either a specific
threshold_claim / issue or the case as a whole.
Data model
- case_precedents (SCHEMA_V5_SQL) — case_id, section_id NULL/
"threshold_N"/"issue_N", quote, citation (free-text), chair_note,
pdf_document_id FK to documents, denormalized practice_area for
cross-case library filtering.
- Deliberately NOT linked to the existing case_law table — that one
has UNIQUE(case_number) which would force parsing the free-text
citation into a structured key. A backfill pass into case_law is
a later follow-up once the UI stabilizes.
- db.py gains 4 helpers: create_case_precedent, list_case_precedents,
delete_case_precedent, search_precedent_library. The last uses
DISTINCT ON (citation) for the cross-case typeahead so each
precedent appears once even if reused across many cases.
MCP tools (legal_mcp/tools/precedents.py)
- precedent_attach, precedent_list, precedent_remove,
precedent_search_library — registered in server.py.
FastAPI (web/app.py)
- POST /api/cases/{n}/precedents — create, with PrecedentCreateRequest
- POST /api/cases/{n}/precedents/upload-pdf — one-shot PDF upload to
a dedicated documents/precedents/ subdirectory, creates a
documents row with doc_type="precedent_archive" and no text
extraction (archive only)
- GET /api/cases/{n}/precedents — list
- DELETE /api/precedents/{id} — uses path param since precedent_id
is a UUID (slash-safe, unlike case numbers)
- GET /api/precedents/search?q=...&practice_area=... — library
typeahead
Block-writer integration into _build_precedents_context is a deferred
follow-up — Phase 1 surfaces the feature in the compose UI only.
