Two independent RTX 5090 validations agree within noise:
- #619 (@paulp83): first NVFP4 boot on Blackwell — verify-full 9/9,
verify-stress needle-clean, soak-continuous PASS.
- #612 + #652 (@guybrush01): verify-full 9/9, verify-stress to 120K
(91% of 131K), soak PASS, p50 ~311 TPS. (#652 re-confirms #612 within
noise — one rig confirmed twice.)
status experimental -> caveats + compose header Status/Caveats. Caveat =
8-pack quality NOT yet cross-rig-measured (sandboxes weren't built on
these runs; quality run pending, gated on #492) — reverts to experimental
if a quality run regresses. NVFP4 stays Blackwell/Hopper-only (sm_90+).
Unchanged: 27b-single-nvfp4 (shipped util OOMs a 5090 — #613/#617, needs a
config fix) and both dual-nvfp4 slugs (no reports) remain experimental.
