Slice 1: intent.Hub records one start/end per GET /api/v1/wait request and answers
Presence(customer, now): connected (hold open, or one started < 333 s = 243 s cadence + 90 s
grace ago), not connected since T, or unknown (hub up < 333 s; in memory only). The host page
shows "Box connection". One DEBUG line per presence change.
Slice 2 (operator ruling D2, 2026-10-08, 09 §3 decision 186): a host that is online by its report
clock but whose box has had no wait-channel connection for >= 360 s may be deleted at once after
the tick "I checked: the box is off". Presence is re-read at POST time; the tick alone, unknown
presence, a connected box or a shorter gap keep today's 409. The delete logs the operator channel
and saves one host_deleted_box_off event. RESET and the customer-delete cascade are unchanged.

GET /api/v1/wait long-poll: the box holds an authed hanging GET; the hub
completes it the instant any operator intent bumps that customer's in-memory
generation, then the box fires its ordinary report and the ACK delivers
everything through the unchanged machinery. 240s hold with a 25s heartbeat
newline defeats the nginx 60s proxy_read_timeout with no ingress annotation;
WriteTimeout lifted per-connection via ResponseController.
- internal/intent: per-customer generation counter + waiter registry
(Bump/Wait/Close), coalescing to latest, race-closer, in-memory by design.
Red-proofs: counter-vs-queue + race-closer (run-fail-reverted).
- api/wait.go: the endpoint (per-customer only; global key 400; A cannot see B).
- web bumps after every intent write (fire-after-commit): config CRUD, claim
resend, offsite re-issue/freeze, password regen, block/unblock, floors
(global bumps all config-managed), controller log-tail + log-bundle.
- main.go: one intent hub shared by web+api; Close() before server.Shutdown.
Pairs with controller v0.140.0 (the long-poll client). Grounding:
