MathCheck Engine 0.3.3

Validated Engine 0.3.3 wheel from native gate source 2556e1f. The unchanged joint native gate passed under QEMU WHPX with stock Lean 4.23.0. Engine live suite: 96 passed, 52 subtests passed. Wheel SHA-256: da94438427e02382c80dcf366c540c3e625e552966d7c873516aaca7790f6782. Full report, environment record, manifest, and stage logs are attached; RL closeout evidence is in https://github.com/stanleyngugi/mathcheck-rl/tree/main/docs/evidence/native-closeout-whpx-20261005-final.

MathCheck Engine 0.3.2

Corrective MathCheck Engine release with truthful Python compatibility metadata.

Changes:

• requires Python 3.11 through 3.13 (>=3.11,<3.14)
• removes the incorrect Python 3.10 classifier and adds Python 3.13
• adds a regression test keeping package metadata and the runtime version aligned
• no verifier semantics or supported mathematical contracts changed

Validation: 71 tests and 42 generated subtests passed, including live checks through an isolated Lean 4.23.0 toolchain. The complete clean release gate passed twice with byte-identical wheels. See release-manifest.json for the exact Lean digest, build-tool versions, and artifact hashes.

MathCheck Engine 0.3.1

First public MathCheck Engine release.

Highlights:

• bounded integer evaluation, sums, counts, and minima
• complete finite-pair certificates
• explicit verdict taxonomy and digest-bound evidence
• opt-in fail-closed Linux isolation with Lean 4.23.0
• documented trust boundary and future contract roadmap

Compatibility: the Python distribution remains lean-kernel-verifier and the import remains lean_kernel_verifier throughout the 0.x line.

Validation: 70 tests and 42 subtests passed. The clean release gate passed twice with byte-identical wheels using Lean 4.23.0. The GitHub-hosted job is pending because the account billing lock prevented a runner from starting; no workflow step failed.
