Checkpoint 0.1.0

Checkpoint 0.1.0 is a local investigation workbench for explicit Python workflows.

Record a failed run, inspect its step inputs and supported HTTP, execute a strict replay, create an immutable input experiment and compare its result with the original. Export either an inspection bundle or a runnable reproduction with explicitly selected code, data and recordings.

The release includes Windows x64 and Linux x64 binaries with the interface embedded, fictional examples, an installable Python SDK and checksums. Python 3.11+ is required. The recorded browser demo supports inspection and comparison; execution stays on your computer.

The packages were tested through clean Windows and Debian-container installations, including a separate file-backed workflow and three actual exported reproductions. Recovery checks include real engine interruption, supported descendant cleanup and uncertain external outcomes. Measurement method, hardware and raw samples are in docs/performance.md.

Start with the README. Only explicit SDK HTTP is replayed; this is trusted local Python execution.
