QRdata — P0 channel benchmark

Throwaway channel-qualification tool (WO-P0). No network use, no analytics, no fonts.

Feature detection

This panel feeds the device inventory export. Scope note: the zero-request claim covers this page only — it cannot certify the device's other traffic.

Cell selector

Run identity (operator-entered, persisted in this browser, stamped on every record)
Annotations (recorded into the export)
Receiver decode arm

Gate evidence comes from the imageData arm (default). videoStream cells are optional bonus data, never gate evidence (D-2026-10-01-04).

Export

The export emits exactly: the planned cell list (36 matrix cells + the four §5 arms); the cells actually run (per-rep records joined by cellId, with wall-clock startedAtIso/finishedAtIso, deviceName, pairingId, session and fingerprint stamps); a computed coverage block (recordedCellIds, missingCellIds, extraCellIds, repsPerCell vs planned, coverageOk); the per-pairing per-cell timeout medians and sample counts; commanded vs achieved sender fps with cadence flag and module render resolution (moduleDevPx, renderUpscale, renderDegraded); per-rep frame accounting (framesSent/framesDecoded/framesNoDecode/framesUnreplied/skippedFrames/lostReplies) with stalled reps flagged; annotations; and a loud flag on any record from a foreign session or device. Received content is inert — nothing decoded is ever executed or auto-opened.
