Trim the new event-silence file from 8 tests to the 2 that bind the fix: the deaf-socket e2e through `_liveness_loop` (transport green, no DISPATCH → probe trips with the `event_silence` reason) and the None-stamp window reading healthy (no false trip on quiet reconnects). The removed cases re-checked knob parsing, defaults and the YAML seed loop already covered by the sibling liveness knobs' tests, or restated the two kept invariants from a different angle.
