supercode-harness 0.4.20

//! ORCH-16 (observed tier): the inbound-trigger noun — an HTTP route or hook
//! mapping that opens a turn when something outside the harness fires.
//!
//! * **Hermes** — dynamic webhook subscriptions in
//!   `HERMES_HOME/webhook_subscriptions.json` (a flat map `route → {description,
//!   events, prompt, skills, deliver, deliver_extra{chat_id}, created_at,
//!   secret}`, written by `hermes webhook subscribe`) plus static routes under
//!   `platforms.webhook.extra.routes` in `config.yaml`; each serves
//!   `POST /webhooks/<route>` (`gateway/platforms/webhook.py`).
//! * **OpenClaw (pinned 2026.7.1-2)** — the `hooks` block in `openclaw.json`:
//!   `enabled`, `path`, `token`, and `hooks.mappings[]` (`id, match{path,source,
//!   event}, action wake|agent, agentId, sessionKey, wakeMode, deliver, channel,
//!   to, model`); when enabled the gateway also serves the built-in
//!   `POST <path>/wake` and `POST <path>/agent` endpoints
//!   (`docs/automation/cron-jobs.md#webhooks` at the pin). NOTE: `openclaw hooks`
//!   at the pin manages INTERNAL lifecycle hook packs, not these.
//! * **Claude Code** — channels are declared over the MCP protocol at connect
//!   time, not in a file; refused rather than guessed (as ORCH-14).
//!
//! Read-only, and no secret is ever read for anything but presence: the
//! per-route HMAC `secret` (Hermes) and the hook `token` (OpenClaw) are never
//! emitted.
