Nitro still waited indefinitely at race start with both ROMs after the media, boot and interrupt-sampling corrections in PR #4. Pin Copper68k 1.5.4-nitro-dev.2 from CPU PR #24, which completes memory BTST's required final fetch after delayed reads. Nitro now renders its first race and responds to driving and steering input with native Kickstart and the source-built CopperStart ROM.

The package is distributed unchanged through the owner-approved full GitHub release, with no NuGet.org publication. Update all five locks and the preparation script to fetch those exact frozen bytes, retaining SHA-256 and lock SHA-512 verification. No sibling source reference, game-specific patch or host OS service is added.

Validation:

• Each ROM completes the unchanged 14,000-field Nitro script; all 355 image/state/RAM/PCM captures match between batch/scalar modes. A neutral-input control matches 280 files through field 11,000 and first differs after acceleration at 11,200. Lotus 2 reaches its first Forest Course race with all 355 mode-comparison files matching.
• Production Release build: zero warnings/errors. Engine: 1,247 passed, seven optional native skips. Host: 195 passed, six optional native skips. Both exact-ROM CIA clock probes pass with the final package.
• Source CI: 5,417 CPU tests passed, 109 optional/deferred skips; 86,663,530 logical cases in 783 validated batches; 18 AHX shared-dependency tests passed. The duplicate local full CPU run was cancelled after that completed CI coverage; its partial results remain incomplete.
• All 24 focused delayed/ordinary BTST cases pass on the frozen package. Twelve delayed-read cases fail before the CPU correction. The flag-order negative control, existing interrupt regression and independent Moira comparison are retained in the evidence.

The qualification record identifies exact source/package/ROM/media/input hashes, publication verification, the bounded frozen-component CopperStart build and earlier producer-suite limitations. Coverage is bounded to first-race play; later races, game completion, audio fidelity and physical timing remain unverified. Optional/deferred skips are unavailable coverage. No ROMs, media, build artifacts or credentials are committed, and these diagnostic runs are not throughput acceptance measurements.
