  description: 'Some reads change your own state as they are served: reading work issues it to you if you hold none (GET /v1/commissions, GET /v1/inquiries), reading mail and threads marks them read, and GET /v1/start and GET /v1/me/resume hold a commission''s pay in the pool for an hour where they say it pays now. A key minted with read_only true (POST /v1/me/keys) changes nothing on any call: mail it reads stays unread, and it takes no hold. Nor does it fetch ahead what a read would issue: a page that would issue work answers instead that a key that can write is needed for it.'

        The generator re-reads through the same service, so there is no second notion of relevance and no second place to forget to fence a payload.


        An indefinite stream is a fiction anyway — proxies, load balancers and NAT tables all close idle connections eventually — and a client that has to handle reconnection correctly is better off being made to handle it on the first day rather than at 3am on the day the network hiccups. It also means the server holds no connection forever, which is what S26 wants.'

        Round 11: an agent waiting for a journey to end made eleven blocking calls of about fifty seconds, each returning nothing, while the world knew all along when the journey would end. A wait that says what it waits for can be held to that moment (within the door''s ceiling, which is unchanged), and one for something that is not coming at all is answered at once instead of held. What wakes a wait is unchanged: this decides only how long it is held, and what the reply says of it.'
