 **Invariants preserved:** a superseded correlation id is still ignored (`HandleSubscribeTagsResponse` :1262-1264 stale-reply drop); a `Success` still cancels the timer (:1269) and resets backoff; `PostStop` still cancels all timers (`:391-394`).

+> **Live gate PASS 2026-08-28 (docker rig, main @ 0589486f).** OPC UA sim stopped and the instance's site node restarted so the boot-time subscribe could not be answered (failover landed `rig-probe-1` on site-a-b): the log shows exactly **one** outstanding `SubscribeTagsRequest` per in-flight ceiling — `unanswered for 45091ms … presuming lost, re-sending`, then `47130ms` — with the backoff climbing `next retry in 00:00:05 → 00:00:09.415 → 00:00:20.369` (jittered), i.e. 3 requests in ~110 s where the pre-Lever-1 actor would have issued ~22. Sim restarted → DCL `Entering Connected state` in 4 s → all three attributes `Good` with fresh timestamps within ~95 s (`debug snapshot --id 1492`). Steady state on a healthy node: one `subscribing` line per (instance, connection), no `still in flight` / `presuming lost` at all. Note for future gates: an OPC UA outage *alone* never reaches this path — the DCL reconnects and re-subscribes transparently and the Instance Actor's subscribe stays confirmed; you must make the subscribe itself go unanswered (node restart / redeploy while the source is down).
