fleet-delivery

1// fleet-delivery: delivers the seat's Room inbox and pending job results into
2// the session through $.prompt.submit, one prompt per item, in place of the
3// supervisor typing them into a pty. Inert unless installRoot is set, the seat
4// resolves, AND <installRoot>/.aigent/delivery-owner.json says
5// {"owner":{"<seat>":"mod"}}.
6// Fences: never asUser (the model must read a delivery as the plugin's, not
7// the person's words); no $.permission or tool-approval calls; no network;
8// writes only the plugin's own state and store and the seat's log file; one
9// host process only (job-results.mjs `pending`), never started unless that
10// script exists. The Room inbox is read, never moved: $.fs has no rename or
11// delete, so a copy into processed/ would leave the original behind to be
12// delivered twice.
13// What was delivered lives in $.state (versioned, shared by an old module and
14// its hot-reloaded replacement, so a claim is a compare-and-set) mirrored to
15// $.store (kept across sessions). The JSONL file is an append-only log for
16// people, each line length-prefixed so a torn write is caught, never read as
17// "nothing delivered".
