An 80ms fade only got it to -26.8 dB (verified by ratio against the unfiltered master), i.e. hidden, not gone. Dropping the burst outright (end 45ms early) removes it; the 30ms fade then keeps the new edge from clicking in turn.

Then 2026-08-16, having heard it: 'approved #13 seam, but lets add after seam 2s silence in crime file, then seam is start of REVOLUTION' -> pad_end_s 2.0. This is a REST, not a trim artefact: the 2s belongs to CRIME (it ships inside track 13, and inside the continuous mix at the same place), so the last official track ends on its own silence and the encore starts clean. Note the ducked fade is kept AND the silence added — the duck softens the cut, the rest separates the encore; they answer different complaints."
