Fold a time-domain impulse response into the SAME RoomTransferAccumroomTransferAccumulate
produces from a run of frames — the seam the log-sweep path (spec §3a amendment 2026-09-21)
uses to feed the shared IR/transfer readers without minting a second representation.
The IR is zero-padded to the next power of two, forward-transformed, and its one-sided spectrum
kept over the SAME band selection roomTransferAccumulate uses (kLo/kHi from band).
Coherence reads 1 inside the band: a single deterministic swept-sine deconvolution is fully
correlated by construction — coherence is the live pink read's N-frame statistic, not this
path's, whose confidence is SNR/distortion (spec §3a amendment). frames reports 1 (one sweep).
Refuses the same vocabulary the frame-fold does: shape-mismatch when the transform cannot run,
empty-band when the band selects no bins, no-shared-energy when the band is silent.
