"""Tests for the Matrix-intake CRM surface (v0.1.0 Matrix-intake M2).

The bot adds no parallel write path — it reuses /api/fundraising/log-communication and adds
one read-only lookup, GET /api/intake/match. This boots the REAL server against a temp DB and
asserts:
  - match by normalized name and by contact email, returning the GRID ROW id;
  - the new-vs-existing contract: a bot-style create (log-communication +
    create_investor_if_missing) then matches by name — so an approved note lands on that same
    investor instead of duplicating it;
  - provenance: an intake-sourced communication is audited with source="matrix_intake";
  - guards: missing q/email -> 400, unauthenticated -> 401.
Synthetic data only.

Run: cd backend && python3 test_intake_endpoints.py
