Channels

• Email via Resend (heartbeat sends from ops@simplefunctions.dev).
• AgentMail loop for AI replies — the digest is sent as a thread the user can reply to, and replies go to an LLM that has read access to SF state.
• CLI via sf heartbeat <id>.
• Per-thesis heartbeat — every thesis has its own heartbeat config that triggers monitor cycles.

​
