Extend docs/guides/email.md paths: frontmatter (and its AGENTS.md index entry) to
include backend/digest_mailer.py and backend/smtp_send.py, so the guide auto-loads
when editing the outbound-digest send path — not just backend/email_integration/**.
Portability-checker: compliant.
- docs/guides/email.md: new "Outbound mail — the daily digest" section (Gmail-DWD
primary → SMTP fallback; gmail.compose send capability; the internal-digest
exemption from the agents-draft rule).
- AGENTS.md: add digest env names (CRM_DIGEST_SENDER, SMTP_*); consolidate the
v75/v76 deploy bullets into one current bullet; drop finished v74 narrative.
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.
