The standby-sink stall program's §3 dead-end list marked ADL EmulationMode 'likely Pro-gated' on field hearsay, with 'probe once, log rc' as the owed falsification — never run. Three RX 9070 XT field cases later (ASUS VG32VQ1B/DP, Odyssey G60SD/DP, LG UltraGear 32GS95UE/HDMI), this is that probe, shippable to reporters: read-only caps/board-layout/connection-state walk by default, --lock pins the live EDID + ADL_EMUL_MODE_ALWAYS on occupied connectors (the software HPD-holding dummy), --unlock restores. Every call prints the bench's epoch_ms correlation line with the decoded ADL rc — ADL_ERR_NOT_SUPPORTED(-8) vs ADL_OK on consumer Adrenalin is the Pro-gating answer, and a --lock run during a stream with the sink asleep is the direct A/B for the metronomic stall class. atiadlxx.dll is bound dynamically (absent = clean exit 2), structs mirror adl_structures.h verbatim, and the probe touches only connectors the board-layout walk enumerated. Gates: check/clippy -D warnings (msvc cross-target) + fmt clean; native stub unaffected.
