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:
