"""Regression test for the Grid-detail communications timeline filter (Phase 8c, G6).

The mobile Grid detail's notes timeline pulls an investor-level communication stream
via GET /api/communications?source_row_id=<grid row id>. That filter (added to
handle_list_communications) maps the grid JSON row id → fundraising_investors.source_row_id
→ fundraising_contacts.contact_id → communications, so it must:
  - return every communication across ALL the investor's contacts,
  - stay isolated (one investor's row id never returns another's comms),
  - respect soft-delete (cm.deleted_at IS NULL) through the join.

Boots the REAL server, seeds investors by driving the one-row log path (which creates the
grid row + contact + communication AND syncs the relational mirror the filter joins on),
then drives the live read path with a real token. Synthetic only (guardrail #9).
