The impulse response and its early reflections from an already-folded accumulation — the body
of roomImpulseOf, shared so a stimulus that produces the per-bin estimate another way
feeds the SAME envelope search rather than a parallel one. The log-sweep path (Room Analysis
§3a amendment 2026-09-21, room-sweep-stimulus.ts) forward-transforms its deconvolved IR into a
RoomTransferAccum (accumFromImpulseResponse, room-transfer.ts) and enters here unchanged:
one accumulation shape, two stimuli, one reflection reader.
