A session that has gone away does not appear here — it is reported as gone (NRY-0009) when addressed, never as available. ## OpenAPI ````yaml /en/openapi/v3-current/narya.yaml get /v1/peers openapi: 3.1.0 info: title: Narya Host API version: 1.0.0 description: >- The contract between the Narya host and every client. One long-lived host runs on your machine and serves this API over a Unix socket in your Narya home. Narya creates the socket owner-only, and file permissions are the whole authorization. There is no password, no token and no TLS. The terminal client and the one-shot command that Lerian ships drive this API, and a client you write drives the same one. Results never arrive on the response of the request that caused them. Submitting a message returns 202 with a turn id. Everything the turn produces streams over GET /v1/events as server-sent events with a typed envelope, and a stream resumes from a Last-Event-ID header. One error envelope: code, title, message, and fields on 422. Codes are NRY- followed by four digits. A paged list answers items, limit and a nextCursor when more remains. Cursors are opaque. servers: [] security: [] tags: - name: host description: The host process itself — version, uptime, mode, store. - name: sessions description: Durable conversation containers.

A session's `title` is model-authored, duplicable and may be absent, so it is what a person reads in a list and never what a message is routed by; no third name exists to sit between them. Carried alongside `sessionId` because the field is required and predates that ruling. status: type: string enum: - idle - running - waiting liveness: type: string enum: - addressable - gone description: >- Whether a message sent right now would reach this session. `addressable` covers both a free session, which takes it into its transcript immediately, and a busy one, which takes it from the durable queue when it frees. `gone` is a session that exists but that nothing is serving — a row a dead host left claiming a turn — and addressing it is refused (NRY-0009) rather than queued for a recipient that will never read it.
