Validated automatically
Known delay recovery, inverted polarity, noisy correlation limits, repeated-run jitter, DC offset, balance, crosstalk, dropout, and experimental THD fixtures.
Validation report
Show where the method holds.
Electrical loopback estimates are validated against known synthetic returns in the automated suite. They remain browser-local whole-path estimates, not converter specifications.
Withheld when invalid
Missing electrical-path confirmation, clipping, weak correlation, or unsupported stereo capability withhold affected metrics.
Release gate remains
Physical multi-browser and multi-interface comparisons require real hardware runs. They are not represented as complete here.
