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.
