 Largest metric deltas over all sources and the three conditions: |LUFS| 0.017 dB (tract), |true peak| 0.152 dB (thruster, old pinned), |centroid| 0.16 % (soft-triangle; the earlier core run has 0.3 % at thruster rpm600). **No gate flag differs on any source in any condition**; the tract's patch-group `FAIL onsetMs` is on both sides (see above).
 
 What the data says:
 
-- With imp(3) pinned on both sides all 13 rows agree to -75 dB or better (Ding instruments -130 to -142 dB, thruster -99.9 dB, tract -109 dB; worst: `advanced-bird-syrinx-graph` -75.4 dB). `dx7-algorithm-32-additive-organ` sits at -79.5 dB under all three conditions, so its residual is not the pinned smoother (a smoother inside a library function, or float rounding; not isolated).
+- With imp(3) pinned on both sides all 13 rows agree to -75 dB or better (Ding instruments -130 to -142 dB, thruster -99.9 dB, tract -109 dB; worst: `advanced-bird-syrinx-graph` -75.4 dB). `dx7-algorithm-32-additive-organ` sits at -79.3 (library), -79.5 (old) and -79.5 dB (imp3), so its residual is not the pinned smoother (a smoother inside a library function, or float rounding; not isolated).
 - With the old smoother pinned the thruster still differs (-21.2 dB): native's LLVM contracts the recursion to FMA and stalls at 4797.657 instead of wasm's 4796.632. The old form's stall point depends on the arithmetic; the imp(3) form does not.
 - As shipped, nine of the 13 rows differ at waveform level by -16 to -50 dB (thruster, the three syrinx patches, the larynx graph, all four Ding instruments); `advanced-alien-multivalve-graph` (-68 dB), the tract (-52.6 dB) and the two dx7 patches are closer.
