Validated GCC/ISS and privileged-architecture release.
Evidence highlights:
- 70/70 stable regression and 60/60 functional bins
- 85/85 compiled-firmware executions with 178/178 points and 94/94 crosses
- 12/12 Spike differential programs and 45/45 ACT4/Sail architectural tests
- 3/3 RV32 formal groups, 14/14 RTL mutations, and 5/5 external-oracle mutations
- 26/26 low-power targets, 4/4 UVM smoke tests, and 4/4 integrated CDC ratios
The release workflow requires the pinned external validation tools. Results remain open-source pre-silicon evidence rather than RISC-V certification or commercial signoff.
