Full gate complete on the reference 2x3090: verify-stress 8/8 (NIAH
clean to 240,635 tok = 91% of 262K, ceiling margin 1,801 MB, zero drift
across the ladder) + soak-continuous PASS (0 errors, 0/25 silent-empty,
0 VRAM growth, p50 215.9, 100% retention), joining the existing bench
(179.5/179.4 decode) and 8-pack (103/150 tie) results.
Caveats (why not full Production): streaming tool-calls + thinking-on
hit finish=length (known family class, verify-full check 6); native-FP4
quality remains unvalidated (all numbers are the Ampere W4A16 bound).
