apphandoff

1// AppHandoff for Claude Code — the plugin's hooks module: the inbox add-on
2// (HO-16353) and, composed in by `register`, the touched panes (HO-17539).
3//
4// Wakes this chat when someone else posts on a ticket it claimed or created,
5// when a person decides a milestone approval it asked for (HO-17707: read
6// from the board's notice list, the catch-up every IDE reads), and when a
7// person accepts or drops a milestone this chat or its builders worked on
8// (HO-19052: followed from its own plan calls, no proposal of its own). Watched
9// tickets are polled with one `message` notify_config watch call per project, then
10// one `get` per ticket it names as changed (HO-19546); a connection that cannot make
11// that call reads every ticket with `get`, as before. Before it wakes the chat for a new message it
12// claims the ticket for the chat (HO-19659: the plugin's one board write, under the chat's own
13// agent id; another agent's lease means no wake), and it wakes the chat when a person answers
14// a board question the chat asked. `/inbox standby <project ids>` (HO-19660) makes a chat a standing
15// inbox: it claims, one a poll, a message nobody answered six minutes after it was posted
16// and wakes the chat for it (a board question for a person's message, a reply-only wake for an outside
17// agent's). Every decision
18// lives in ./inbox-core.ts (pure, unit-tested); this file only moves what the
19// engine says into it and acts on what it returns. Nothing here may throw
20// into the chat: every hook and timer path catches.

18//   leaves the pane learn-only; neither reads again. Those rows join Waiting on
