Phase A.2: a refcounted micro-probe engine (fence round-trip per adapter, DwmGetCompositionTimingInfo tick, watchdogged DwmFlush, Level-Zero D3DKMTGetScanLine, CPU jitter sentinel) samples continuously on detached sacrificial threads; each stall report reads the window back and the verdict matrix folds it with the driver telemetry into a named class: ours-worker / ours-delivery / CLASS-1 adapter freeze / CLASS-2 compositor blocked / frame-generation / unattributed. The metronomic WARN carries the per-class session tally. Phase A.3: an event-id-filtered real-time ETW session on Microsoft-Windows-DxgKrnl (QueryChildStatus 150/151, SetPowerState 154/155, IndicateChildStatus 272, SetTimingsFromVidPn 430, DisplayDetectControl 1096/1097) rides every stall line as a DDI bracket summary — naming the servicing call and its duration instead of 'below Windows'. Degrades to etw=unavailable without admin; probes degrade per-leg (absence is stated, never guessed). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
