IT IS ITS OWN OPERATION AND NOT THE ONE A PERSON USES. A home serving this writes the list and stops, because it holds the copy and has no far end of its own to tell. One road serving both halves would make a home that is both ends of a publish have to recognise its own call, and by the time that call arrives the list is identical on both sides of it — so the only fact available to recognise it by is the one fact that says nothing. SETTLING THE SAME LIST TWICE IS NOT AN ERROR, and it is not skipped either: a home repeating this is a home whose first attempt it cannot know the fate of, and the state asked for is the state it gets. WHO MAY CALL IT is who may change an audience anywhere — the person who published the share, or a member carrying `members:manage` — and the call travels as the person ASKING rather than as the person who published. That is what lets a departed colleague's conversation be narrowed at all: nobody holds a credential for somebody who has left, so a call that had to travel as the author would wait for a sign-in that never comes. A share this home holds no copy of answers 404, and so does a revoked or expired one: there is no audience here for the list to apply to, which is the state the caller asked for. ## OpenAPI ````yaml /es/openapi/v3-current/narya.yaml put /v1/shares/{shareId}/audience 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 serves this API over a Unix socket in your Narya home. The terminal client and the one-shot command that Lerian ships drive this API, and a client you write drives the same one. Requests authenticate with a bearer token issued by the identity provider the host is configured with. An operation that declares another security scheme also accepts that credential. A request without a valid credential gets 401 with NRY-0011. A caller whose role lacks the permission an operation needs gets 403 with NRY-0028. 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 and message. Codes are NRY- followed by four digits.

THE WHOLE LIST AND NOT A CHANGE TO ONE. What is sent is what the share names afterwards, so adding a colleague and removing another is a single act with a single answer — a body that carried "add these, remove those" would be two lists that can contradict each other and a third rule for what happens when they do. ABSENT OR EMPTY IS THE WHOLE ORGANISATION, the ordinary publish and the default — never "a share nobody may read". It is how a share narrowed by mistake is widened again without republishing the conversation. Naming somebody twice is the same grant said twice and is kept once. A value no sign-in could report — a blank, a pasted line — is refused by name with 422, because a share addressed to a typo is a share readable by nobody answered with a success. properties: recipients: type: array items: type: string description: >- The subjects of the colleagues this share is for.

Requests without a valid one receive 401 NRY-0011. The socket's file permissions are transport and are not an authorisation. ````
