Read strict versioned suite manifests with independent ROM cases, explicit ARM/Thumb checkpoints, register/CPSR/memory assertions, and aggregate step limits. Report every case deterministically and fail on timeouts, STOP, diagnostics, missing files, or mismatches. Keep host JSON dependencies outside the core. Add an original ARM/Thumb/BIOS suite generator, unit and process-level regressions, and schema/usage documentation. Verified on Darwin arm64 with debug/release workspace and core suites, Clippy, rustdoc, native ROM-window tests, all ten demo smoke tests, repeatable release reports, and a deliberate assertion failure. Independent public hardware-test ROM validation remains next.
