They timed the wraps instead of converting them -- a probe stamping read_offset on arrival, three wraps observed, each from its own loop_end to its own loop_start, both contexts wrapping at the same instant. Cycle 61.81 s against the 61.93 authored here: 0.2 percent, from a wall clock between decoder events versus an autocorrelation that never touched the wave. The window is wrong: loop_start is 11.6 percent into the stream, about ten seconds, so this export has the right duration over the wrong window -- replaying the intro every cycle and omitting the tail the game plays. Not re-cut, on their instruction: the exact start is unmeasured and linearity is refuted by a 4.4 percent rate variation within one stream. But loop_end_s alone silently asserted a start of zero, so the entry gains loop_start_s, authored as 0.0 and flagged wrong, with -ss applied before -t so the pair is (start, duration). Proved before it is needed: loop_start_s=10 yields -ss 10 -t 61.93 and a 61.930 s output. Restored to 0.0, export byte-unchanged. My smooth-join check gains a use I could not have anticipated: it explains why a wrong ten-second window went unheard, because a cut near a zero crossing is smooth wherever it falls.

Authored decisions
Everything here is a decision we made, not something the disc said. It is
hand-written, committed, and survives a re-export — unlike export/, which is
regenerated wholesale and must never be hand-edited.
Every entry carries a why. When the RE agent decodes the real answer, delete
the entry and let the exporter emit it; that deletion is the measure of
progress.
See docs/FORMAT.md for the schemas and docs/BLOCKED.md for which HANDOFF
question each placeholder is standing in for.
