New backend/matrix_intake/ runs as its own process (matrix-nio isolated from the
stdlib CRM): local-Qwen parse via Spark Control → in-thread human approval
(yes/edit/no) → write through the CRM's own log-communication endpoint, tagged
source=matrix_intake. Adds read-only GET /api/intake/match (returns grid row id,
no-duplicate contract); threads provenance through handle_log_fundraising_communication.
Reviewer-passed: pop-before-commit closes a double-approve race; edit-grammar fix.
Text-only v1; business-card photo (M3) deferred (no Spark vision model).
26/26 tests green; live Matrix smoke pending deploy.
Move subsystem mechanics (migrations, thesis gate, redaction, ingest,
email, packaging) out of AGENTS.md into docs/guides/<topic>.md, each
scoped by paths: frontmatter and symlinked from .claude/rules/ so Claude
Code lazy-loads them. AGENTS.md keeps whole-repo facts and universal
guardrails plus a one-line index per guide. Fix the inaccurate
".claude/ is gitignored" note — it is tracked.
