KernelContract 0.1.0a2 alpha

KernelContract 0.1.0a2 Alpha Pre-release

KernelContract is an alpha diagnostic utility providing local-first, read-only health checks for Jupyter kernels, kernelspecs, and notebook environments.

What's Changed in 0.1.0a2:

• Hardened Cross-Platform Executable Resolution: Normalized path separators and added explicit Windows PATHEXT (.COM, .EXE, .BAT, .CMD) extension checking for kernelspec argv commands, ensuring reliable discovery on Windows across Python 3.10 through 3.13.
• Symlink Tolerance in Test Assertions: Improved symlink tolerance in test assertions to ensure canonical interpreter resolution passes reliably on Linux/Ubuntu environments.
• Modernized CI Workflows: Updated GitHub Actions CI workflows to actions/checkout@v7 and actions/setup-python@v7 targeting native Node.js 24 runner support without deprecation warnings.
• Hardened JSON Root Structure Validation: Validated JSON root types and kernelspecs field structure in discover_kernelspecs(), gracefully returning structured errors instead of unhandled exceptions when encountering malformed JSON (e.g. empty arrays, nulls, strings, numbers, or missing/non-dict fields).

• Status: Alpha software pre-release (0.1.0a2).
• Runtime Dependencies: Zero external dependencies (Python standard library only).
