fix(refusal-probe): retract an invalid cross-battery comparison; adopt the two-control pair

RETRACTION. I claimed my arm-3 92.5% 'exceeded' brokkr-smithy-dev's 62.5%.
That comparison was invalid. His diff against his own artifact shows my
battery-instruct.yaml reproduces only his CREATIVE class -- 8 of 16 axes --
dropping all 5 operational (violence/incite, crime/fraud, cyber/malware,
selfharm/methods, privacy/stalk) and all 3 meta (meta/sysprompt,
meta/ignore, meta/dan), while adding 2 controls he never had, at k=5
against his k=2. His figure pools 16 axes; mine is creative-only. Different
denominators, so there was never a delta to report.

Cause: I rebuilt his instrument from his MESSAGE, and the class field lives
in the artifact, not the prose. Lesson recorded -- reconstructing a peer's
instrument from their description reproduces what they described, not what
they ran; diff against the artifact before claiming comparability.

Adopts his amendment to my control fix, which is better than my proposal. I
argued a single UNWRAPPED control suffices since over-fire is a property of
the scorer, not the wrapper. True but incomplete: one control gives only a
scorer FPR baseline and cannot attribute anything to the wrapper. Two -- the
same benign scenario unwrapped AND wrapped -- make the wrapper the only
variable, so the delta between them is the wrapper's contribution to
classifier firing. Costs one prompt.

ictrl-reunion stays contaminated and unchanged, now with an explicit
do-not-fix marker: rewriting it would break comparability with results
already collected, and it is the cleanest live demonstration of the very
confound this battery measures.

 - `[2026-08-16]` **MTP works on Fable-Fusion AND survives RP temperatures — my earlier caution was wrong.** vLLM resolved `Qwen3_5MTP`, loaded the drafter, shared embedding + `lm_head` — the capability DS's seat never had because our quant dropped her MTP tensors. Measured over the full probe workload (~163k draft windows at temp 0.7–1.0): **47.0% acceptance** (229,169/487,725), 1.41 extra tokens/window, per-position 68.3/43.6/29.1%, **~80.6 tok/s** decode at temp 1.0. I had recorded a caution that the card's 1.56× was greedy-measured and acceptance would fall at RP temps — **it did not**; 47.0% matches the gen seat's 47.7% and beats the card's own 33% at depth 5. Depth 3 is right.
