M4: a dead producer left the availability verdict positive forever. The background refresh keeps a positive verdict on a failed probe, which is right for one failure and wrong for a run of them: if the root --service dies while this --server lives, every probe fails, the cached list keeps being advertised, and every display restart-loops. Three consecutive failures now drop the verdict to Unknown, not to Unavailable, because the evidence is about the producer and not about the hardware, so the next enumeration probes from scratch. The cold probe also resets its own failure budget on success: it was never reset, so the five strike allowance was spent once per process and a later probe demoted on its first failure. M6: a display that can never be grabbed churned PeerInfo about every 35 seconds for the life of the process, because the cooldown was flat: demote, wait 30 s, get advertised online, burn four sessions in a few seconds, demote again. The cooldown now doubles per demote cycle up to 8 minutes. Recovery is unchanged in the way that matters, since the count is erased the moment the display delivers a frame rather than decaying with time, so a monitor that comes back is served immediately. Also, while changing that map: a zero-frame session on a display with no connector identity was recorded under the empty key, which is the same aliasing H2 removed for indexes, one unidentifiable display would have demoted the next one. It is skipped now, as the comment above it always claimed. Two new tests cover the backoff schedule and the reported 35 second cycle. 94 tests pass, both configs build.
