m4a_wake.rs

//! Letter wake for live sessions the node adopted (`/m4a/adopt`).
//!
//! The old standalone mailbox daemon woke a session itself: its listener held the account's
//! push socket and pressed the turn on the provider's leader. The node owns the accounts now,
//! so it runs that listener in-process, one thread per adopted account (mail4agent's library:
//! open the account store, sync/push, new inbound letters). The store dedups by event and never
//! hands over the account's own messages; each letter goes to a per-session queue whose one
//! worker pushes it into the live session through the leader (grok: ACP `session/load` +
//! `session/prompt`, `gate4agent_wake::grok_leader`), with the session id and cwd recorded at
//! adoption, so at most one push runs into a session at a time.
//!
//! Adoptions persist in `<accounts root>/adopted.json` (no secret: provider, session id, cwd,
//! nick, account ref, store root), so a node restart restarts the listeners. Nothing here embeds
//! a host, key or name.
