Test the new A/V core
This trial tests pattern recognition. Echoes and phone timing can bias the estimate; physical accuracy is not yet calibrated. Use one audible V2 Test Card, with an expected A/V offset within ±1 second.
Open the matching Test Card on another device →
Positive = audio late. Negative = audio early.
Optional: set a baseline while viewing the source directly, then compare your transmission path. It lasts for this capture session and clears after a restart or large movement.

Live diagnostics
The fit span describes pattern ambiguity, not a physical accuracy bound. This prototype repeats every 6.35 seconds; larger offsets can alias. Gentle packets show an explicitly aged last estimate during quiet gaps.
