Verified Interview Offsets

data/prefix_offsets.json contains only offsets that have been independently verified against the Kani'aina episode audio. Missing prefixes deliberately remain unavailable in the UI rather than receiving estimated positions.

A-KLH-HV24-057

Corpus recording	Episode offset (seconds)	Episode offset (clock)
KLH057a	0.0	0:00.000
KLH057b	2600.5416780045352	43:20.542

Verification: the archived Kani'aina MP3 is 82,541,504 bytes at 128 kbps, which gives 5,158.844 seconds. The upstream KLH057A_notes.TextGrid and KLH057B_notes.TextGrid durations sum to 5,158.843356009071 seconds. The 0.644 ms difference is below one MP3 frame, establishing that the source recordings are concatenated in episode order with no material gap.

The Kani'aina player does not provide a documented URL parameter for seeking, so the app displays the exact position beside its separate Open episode link.
