wake_pipeline.rs

1//! The node's letter pipeline: letter in -> policy -> g4a deliver (or refuse; the letter stays in
2//! the inbox).
3//!
4//! m4a only hands letters over (its `M4A_LETTER_HOOK`, the door `session.wake`); this node's own
5//! mailbox is a second letter source (the node-mail host action below). The node decides what a
6//! letter may do, from an operator file (`--wake-policy <file>`, JSON):
7//!
8//! ```json
9//! {
10//!   "terminal_typing": ["<nick>"],
11//!   "routines": { "<nick>": { "credential_command": ["<program>", "<arg>"] } },
12//!   "spawn_profiles": { "<nick>": { "provider": "kimi", "command": ["<program>"] } },
13//!   "node_mail_to": "<nick>"
14//! }
15//! ```
16//!
17//! - A live session with a structured prompt channel gets the letter as a turn (deliver).
18//! - A raw-terminal session (typing into its PTY) is the terminal capability: refused unless the
19//!   policy names that nick in `terminal_typing`.
20//! - A nick bound to a routine (a vendor-hosted web session) gets one routine POST through g4a's
21//!   deliver API (`gate4agent_wake::routine`). The routine URL and key come from the operator's
22//!   `credential_command` (stdout: `{"url": "...", "key": "..."}`), are kept in memory for the one
23//!   call and are never logged.
24//! - Offline wake: a nick with a `spawn_profiles` entry launches that preconfigured command
25//!   (fixed argv; the letter never becomes an argument).
26//!
27//! Nothing here embeds a host, key or name; all of it comes from the policy file.
