Deep pass: coldwave, triphop, idm, sludgemetal — worst-10 CLOSED

coldwave (margin 0 -> +6): the tie was chinawave (mutual 100/100) — they share ~110bpm/dry triads/crackle/motion; the real musical difference is the drum mix, so it's structural now: chinawave's stated identity is the march snare UP (renders .74-.90), coldwave is bass-forward post-punk (kick up…

• triphop (+1 -> +6): the oldest confusion pair (lofi 99) broken on the claim triphop always had — the SLOWED SAMPLED BREAK (renders breakUse .5) vs lofi's programmed boombap (0). lofi's row simply never read it.

• idm (+1 -> +8): checked the variation-feature hypothesis — it saturates at 1.0 nearly everywhere, can't carry transform density.

• sludgemetal (+8 held, identity deepened): the doom drag — timeFeel pushPull, the whole band behind the beat with the bass draggiest (the amp about to die pulls the riff late)

WORST-10 CLOSE-OUT — darksynth 0->+6, mallsoft 0->+8, witchhouse +1->+7, downtempo +1->+6, newage +1->+5, exotica +1->+5, spacelounge +1->+6, arabpop +1->+5 deepened, coldwave 0->+6, triphop +1->+6, idm +1->+8, sludgemetal +8…
