Fallback
Not used. A date-valid full complex response covers this window.
Claim limit
A passing validation makes these files suitable inputs for separately frozen nominally response-corrected pressure derivatives. It does not establish traceable calibration, response uncertainty, maintenance or calibration lineage, ADC full scale, target-window channel health, measured pressure, received level, ship detection, contribution, attribution, or prediction.
Context & definitions
Waveform response binding

Which response applies here

The binding joins one waveform case to one response instance. Magnitude is visible immediately. Phase stays in the expanded evidence because most readers do not need it until timing matters.
