Nothing lives outside the repo: the bench ixgbe driver source moves in tracked at kernel/ixgbe-sff/ (build artifacts gitignored, load-ixgbe repointed, module build verified from the new home — the reg_ops/ts_bench bench extras are finally versioned), the ice sff_i2c patch is vendored at docs/nics/e810/ice-sff-i2c.patch with its out-of-tree build recipe (TRACE_INCLUDE_PATH fixup, version-matched Makefile), the e810 NVM flash logistics land in the e810 README (exact package name, rollback -m B49691D578EC into the inactive bank, post-flash inventory failing until power cycle is the expected tell), and every ~/work/phydiag-work pointer becomes an inline statement; phydiag-work, ice-sff, e810nvm and the wiitekphy CLI (a duplicate of documented transport+protocol) are deleted

Kernel build workspace moves into the repo at kernel/build/ (gitignored; mkimage anchors to its own path, the pre-mkimage 7.1.4 tarball era swept) and the image's firmware inputs are vendored and tracked at kernel/firmware/ — EDID folded in from kernel/edid keeping its cmdline-relative path, i915 blobs pinned copies from linux-firmware — so EXTRA_FIRMWARE_DIR points at the repo, the assembly step and the linux-firmware host dependency are gone, and a kernel wanting a different blob fails the build loudly

Power: 2 streams and a 2.0 GHz clock pinned by a new checkMaxFreq SETTINGS check (performance governor + scaling_max_freq = fixed clock) take line rate from 80 W to 29.7 W package, qualified 96 s zero-loss; measured on the bench: streams buy scheduling headroom not watts (C1-parked threads, lonelier spinners boost harder), relaxed cpu_dma_latency never reaches deep idle (scheduler spreads wakeups, ~2% residency), offlining E-cores saves 1.7 W and is wire-invisible mid-run, the cliff is TX starvation below 1.6 GHz (1.2 GHz sags to ~18 G, zero errors)

Appliance image builds and boots for the locked-in hardware: kernel/ixgbe-sff.patch carries the product driver subset (raw I2C + sff_i2c, ETQF steering with rule round-trip, FCoE slot guard — bench-only reg_ops/ts_bench excluded), ported to v7.2 and compile-verified; mkimage applies it or dies, builds IXGBE=y (ICE/I40E out with the ice.pkg blob) and puts ixgbe.allow_unsupported_sfp=1 on the cmdline; load-ixgbe joins the repo anchored to its own path; module bringup ordered after the host checks because a down port's TX_DISABLE powers the PHY core down while the mailbox keeps answering (proven by flipping admin state: down reads 0xffff everywhere, core wakes 0.07-0.24s after the raise) with identify settling 3s bounded; cold-boot condition reproduced on the bench (ports downed first) and passing, confirmed on the appliance

Ghost SNR check removed as asked: no bounds, no panic, no latch re-read — a raw 0x0000 in 1.133-136 decodes as no-margin-this-poll (the untrained resting value, which appears before 1.1 reports a drop, so no read ordering could prove a ghost); panel value columns bounded by scalePanelCount (4 chars forever) with RESET narrowed to 5 chars so counts can never reach the timeline; rows and heat cells stretch proportionally to fill the band between header and footer instead of leaving the bottom half dead

Unplugged-cable behavior fixed end to end: heat grid rolls on the slot boundary (view computes the newest slot from the draw clock; history sampled every frame so slots color within a frame; noise phase displayed as commanded straight from the shared clock — radiating and the per-slot vote deleted), SNR ghost panic disambiguated via the PMA 1.1 latch (link dropped mid-read discards the batch, ghost on a proven-up link still dies), measure skips the 25s relink wait when the ECD verdict says faulted and the header says MEASURING instead of GOOD while a diag runs, RollBall mailbox deadline resized to 10s from bench measurement (<25ms linked, ~220ms no-link, >3s during a live plug's training; docs/modules/wiitek updated)

X520 live as the product NIC: rate buckets re-keyed to read time (one shared clock, one commit per drained batch) with the backward smear as a settled window — each completed bucket enters once, donates excess to the nearest earlier deficits once, locks for display when nothing later can refill it (per-sample recompute double-counted excess and read >20G on a 20G wire); timestamp machinery deleted (ts.go, SO_TIMESTAMPING, rx_filter=ALL check) after the audit confirmed the buckets were its sole consumer; testDriver ixgbe; RollBall mailbox hardened against orphaned-command completions (never sample status before a poll gap, value from the same block read, devad/reg echo required — a killed session's 7.60 read answered a PHY ID as 0x0006); full hardware pass: 20.00G flat both directions, zero errors, ECD 42m, SNR +7.4dB
