The v0.33.2 fold moved the payload pin b10488 = 9d77fa172b10630 = d222767c7, so payload_pin failed and everything it guards was suspect until re-measured.

Re-measured first, updated second — no expected value was edited, only the identity moved.

before the pin update PASS=18 / FAIL=1, payload_pin the sole failure — the pin doing its job
after VERDICT PASS — 19 PASS / 2 SKIP

The ladders came back byte-identical to the b10488 rows: nemotron [266, 266, 578, 2306, 3270], gemma4 [1102 × 5], qwen35 [1034, 1034, 1034, 2306, 4082], same budgets and payload proofs, nemotron's pinned budget still 3328 → 3270. The 2 skips are arches with no pinned-budget expectation, by design.

Two firsts

poison_probe ran on CUDA for the first time — our newest previous CUDA run predated it. And it ran with node-level corroboration: the meter (llama/compat/801) was enabled on the container and reported clean over 33 nodes. So the fp16-accumulate class is now asserted at v.blk.31.ffn_down itself rather than inferred from decoded text — the chain from #228 (meter) through #230 (corroboration) works end to end on a real build.

903

Re-checked at b10630 by source inspection: the defect is intact and llama.cpp#27044 is still open, so the patch stays. Recorded in the profile that it must keep hitting only the ids call site — the non-ids path at mmq.cu:137 correctly uses ne11 because its body does too, and a careless regeneration that 'fixed' both would over-allocate the wrong one.

The payload pin moved b10488 = 9d77fa172 -> b10630 = d222767c7 with the
v0.33.2 fold, so payload_pin failed and every value it guards was
suspect until re-measured.

Re-measured first, updated second -- the same discipline as the b10488
re-baseline. No expected value was edited; only the identity moved. Full
preflight on maxusai/ollama:sync-0.33.2 (0.33.2-dynres-5-g2b95b4a)
returned PASS=18 / FAIL=1 with payload_pin as the sole failure, which is
the pin doing its job. The ladders came back byte-identical to the b10488
rows -- nemotron_h_omni [266, 266, 578, 2306, 3270], gemma4 [1102 x 5],
qwen35 [1034, 1034, 1034, 2306, 4082] -- with the same budgets and payload
proofs, and nemotron's pinned budget still landing 3328 -> 3270. After the
identity update: VERDICT PASS, 19 PASS / 2 SKIP (the skips are arches with
no pinned-budget expectation, by design).

903 re-checked at b10630 by source inspection and still required: the
defect is intact and #27044 is still open. Recorded that it must keep
hitting only the ids call site, since the non-ids path correctly uses ne11.

First CUDA run ever to exercise poison_probe, and the first anywhere with
node-level corroboration. The meter (llama/compat/801) was enabled on the
container and reported clean over 33 nodes, so the fp16-accumulate class is
now asserted at v.blk.31.ffn_down itself rather than inferred from decoded
text -- the chain from 801 through the #230 check works end to end.

VERDICT PASS 19/2 on maxusai/ollama:sync-0.33.2
(0.33.2-dynres-5-g2b95b4a); payload_pin re-baselined to d222767c7 with
provenance in #239. Remaining surfaces are unvalidated and the release
table says so.

Re-measured first: the three arch ladders on the sync-0.33.3 canary are
byte-identical to the b10630 rows (nemotron [266, 266, 578, 2306, 3270],
gemma4 [1102 x5], qwen35 [1034, 1034, 1034, 2306, 4082]) -- the third
consecutive pin bump with unchanged numbers. Only the identity moves; no
expected value is edited, as in #239.
