Noise ripped out after the bench verdict (tightly-wrapped unshielded cables move victim SNR only 0.2-0.3 dB, recorded in measurement.md dead ends): noise.go deleted with the noiser, phase clock and panel lane; configureNoise/checkPrivFlag gone so the X710 pair is untouched; console noise column, NOISE links rows and lane colors removed; driverPair rehomed to system.go, carrierUp to phy.go; history anchors to run start (frame-rate sampling and draw-clock roll kept — they fix display latency for every lane); goals/hardware/state/nics docs updated; verified on hardware (20.00G, zero errors, ECD 41m, SNR +7.6)

 | Per-pair SNR | `CMD_GET_SNR` 0x8030, **invoked bare** (writing the documented DATA1 display flag returns zeros; IEEE 1.133–1.140 never populate — constant 0x8080) | DATA2–5 = SNR A–D ×0.1 dB; ≈ 27–32 dB absolute on bench, 0.1–0.4 dB jitter. 10GBASE-T operating point ≈ 26.5 dB, so margin ≈ value − 26.5 — a derived number that never proved actionable, so **cabletest does not poll it** (the panel's SNR comes from an IEEE-margin end — modules/wiitek/ — and each GET costs handler traffic on this µC). **Each training re-converges differently**: back-to-back retrains with identical roles, temperature and noise moved one pair by 3.6 dB (roles pinned, launch power pinned — the convergence itself is the variable, and the two bench modules differ in stability: ≤1.5 dB spread on one, 3.6 dB on the other). A single training's absolute SNR is a weak qualification number; qualification wants median-of-N trainings |
