Groundwork for the daily activity digest: give the CRM an outbound mail path.
Today nothing leaves the box (Gmail capture + drafts only), so this adds a
dedicated, per-package SMTP account independent of any StartOS system-wide SMTP.
- configureDigestSmtp Start9 action: writes host/port/from/username/password/
security to /data/secrets/smtp/* (password piped over stdin, never argv/env;
per-field files, owner-only) — mirrors the setAnthropicApiKey pattern.
- docker_entrypoint.sh reads those at boot and exports SMTP_* (operator env wins).
- backend/smtp_send.py: stdlib smtplib wrapper reading SMTP_* (one code path for
dev .env and the box); starttls/tls/none modes.
- POST /api/admin/digest/test-email (admin-only): proves the pipe. Recipients are
restricted to the active-admin set — an arbitrary `to` is rejected, so the
endpoint is not an open relay; send failures are logged, not echoed (an SMTP
auth error can carry the credential).
- Tests: test_smtp_send.py (sender), test_smtp_endpoint.py (gating + relay
restriction + no-leak). 18/18 backend green; s9pk typechecks.
Analysis/summarization for the digest body (Phase B) will run on Spark, never
Claude — the digest is deliberately un-anonymized. Decisions + Phase B plan in
ROADMAP.md.
Verification against published tarballs confirms ^0.4.0-beta.66 resolves to
0.4.0-beta.66 and its SMTP API surface (getSystemSmtp/SmtpValue,
inputSpecConstants.smtpInputSpec, smtpShape, smtpPrefill) is byte-identical to
the 1.5.3 reference packages. Build against beta.66 as-is; no SDK bump needed.
Research confirms StartOS 0.4 supports per-package SMTP credentials fully
independent of the server's system account: the "custom" branch of the
manage-smtp action (gitea-startos and vaultwarden-startos both) never calls
getSystemSmtp and works on a box with no system SMTP. Record this as the likely
fit (a digest-only mailbox), built on sdk.inputSpecConstants.smtpInputSpec, plus
the SDK version caveat (our ^0.4.0-beta.66 pin vs the references' 1.x).
Fold the research into the daily-digest item: outbound mail uses the StartOS
0.4 system SMTP account via sdk.getSystemSmtp(effects).const(), delivered to the
Python process as env vars from the daemon exec block (gitea-startos pattern,
mirroring the existing setAnthropicApiKey action). Notes the action+storeJson
config model that replaced the 0.3 manifest Config/Properties spec.
Records the requested per-user daily digest (who emailed which investors +
email substance) as a post-Phase-1 backlog item. Notes the three build-shaping
constraints: the new outbound-SMTP dependency (no current send path), the
Spark-only / never-Claude analysis rule for the un-anonymized substance, and
the internal-digest exemption from the "agents draft, humans send" guardrail.
