+## STATUS 2026-07-11: K1+K2+K3 SEALED; D-tier in flight
+- K1 exactness: cos 0.9998-1.0000 on-trajectory + BP-free formally audited (test_bp_free.py in repo).
+- K2 cost: exact mode ~3.6x BP (v7); Sol audit says remaining eager headroom 5-10% (v8 queued).
+- K3 quality: **matched-tuning PARITY n=3** (EP-exact 2.0500±0.015 vs BP 2.0530±0.004 @ C256 L6,
+ lr 1e-3 both). Arc: fake-win (lr artifact) -> fake-tax (v7 dedups) -> parity. Fast mode = documented
+ -4%CE/+20%speed dial. A0.4: TF32 free, bf16 production-only (cos 0.9427).
+- D1a (L12xC512 45M): BP 1.917 sealed; EP + Muon arms landing. D1b long-run demo gated on D1a parity.
+- E-tier: next in queue (softmax pathology / error-channel SNR / write pricing) -> Demo-0 spec sheet.
