Manual witness checklist

Use this checklist after the golden MP4 and synthetic injection gates are green. This is the human/device proof that automation cannot replace.

Device matrix

Desktop Chrome on a current laptop.
Android Chrome on a recent phone.
iPhone Safari.
Desktop Edge or Firefox.
One lower-spec laptop or tablet.

Per-device script

Open the Omega v512 Alpha feedback build.
Tap Enable camera & play.
Open Performance and run Run device check.
Test Practice for 30 seconds.
Test Default for 30 seconds.
Use the recommended mode only if the checker reports a clear winner; otherwise keep Worker CPU.
Test Performer only if Default is usable.
Open telemetry and copy or download witness JSON.
Record whether it was fun/playable or frustrating/unusable.

Launch rule

Gold, funding-gate, and production-readiness claims remain blocked until witness receipts cover the device matrix and the readiness manifest marks the gate green. GPU remains device-local and user-selectable until same-device app-level receipts beat CPU on correctness and latency.
