PC 2 job run-ca3-shadow-pc2-20261006 (card empty, every pack bit-exact against the Mac): the 5090 holds its rate to
150,800 ops per hash and loses 2.7 percent at 199,600 under the app's 431 W cap, which binds from 102,100 ops up and
takes the clock from 3,037 to 1,834 MHz (86 MH/s at 330,700 ops); 350 W at the control, 2.65 to 3.27 microjoules per
hash; marginal ALU energy 10 to 13 pJ per counted op. Clock rows OWED (nvidia-smi refused -lgc without rights). Chip
side at N = 100,000 and k = 1: 2.1x over the 5090 on GDDR7, 0.9x over the M5 Max. GO at mx8+sh256x27.

The M5 Max ladder (Metal, packbench, IOReport GPU and DRAM watts without root): latency-bound to about 100,000 ops per
hash, the 5 percent point about 130,000, 11 to 27 W GPU at 100,000 ops, 0.78 to 1.40 microjoules per hash; the
verifier's law 2.06 ms + 3.2 us per 1,000 shadow instructions per warp on one core; every pack bit-exact. The
analysis file with the knob, the chip side (k = 1, 1.5, 0.3), the gates and the consequences; the bench-log entry;
the 5090 rows pending the PC 2 job (the playbook now carries the core-clock rows and the sh256x40 rung).

A shadow block of S ALU instructions run R times at the end of every iteration, drawn from the program stream after
the 64 base instructions, behind LoadClass::shadow: v2 and v3 draw nothing and emit nothing (the pinned packs are
byte-identical, cargo test 54 + 4 + 19 + 7 green). The interpreter, the three kernel dialects (both kernels each),
program.h and program.json carry it; the acceptance rule interprets the base program only. Packs for seed
igneum-genesis over class mx8 at 4,096 to 180,224 shadow instructions per hash (proto-cuda/packs-ca3-shadow), and
the PC 2 bench playbook tools/ca3-shadow/pc2-shadow-bench.ps1 (passes the publisher's three checks).

f = 0, 0.25, 0.5, 0.75, 1 on GDDR7 (the 5090's board), one HBM3 stack and eight HBM3 stacks, scored in energy per
hash, reads in flight per watt, rate per chip and dollars per MH/s against the RTX 5090 at 136.1 MH/s and 326 W.
The curve is monotone toward f = 1; the f = 1 chip reads 5.1x (GDDR7) to 9.2x (HBM3) per joule in the model and
2.1x to 4.8x by the Ethash precedent: over 2x. The mixer and item 2 do not touch it; the levers named are the
5090's watts under a power cap (a PC 2 job, owed) and program work in the latency shadow. Inputs cited with URLs
read 6 October 2026; the mixer counted from memhard.rs at 128 hoisted / 144 unhoisted ops per application.

One row in the funding table (USD 80,000 to 160,000 for two independent reviews, basis the four RandomX reviews of 2019 at their published per-firm prices and person-days) and a section "The mixer cryptanalysis brief (Counter ASIC 3.0 item 3)": the target shape from memhard.rs and accept.rs, the ranked break list with the chip-model number each moves, deliverables and timebox, the soundness suite to re-run, acceptance criteria in the RandomX audit style, candidate reviewers with citations, the risk column against the two-publish rollout, the timing against the testnet go checklist, and the consequences per user tier. Nothing else in the file is touched.
