Harness Workbench v0.1.0

Harness Workbench v0.1.0 is the first final GitHub release of the deterministic harness-testing workbench. It promotes the verified v0.1.0-rc.2 contents through a new commit, build, signed tag, hosted matrix, and clean artifact-install gate.

Highlights:

• Run command workloads with append-only attempts, preserved specs and feature source, integrity closure, replay, and zero runtime dependencies.
• Measure confinement, effects, blast radius, interruption recovery, steadiness, efficacy, sensitivity, feature interaction, fidelity, and replay behavior.
• Use the public vendor-neutral harness_workbench.capture and harness_workbench.canon primitives for bounded subprocess evidence and canonical digests.
• Materialize the experimental five-subject adapter tree for Claude Code, Codex CLI, DeepSeek Harness, Hermes Agent 0.20.5, and Pi. The shared adapter envelope remains experiment-local rather than a stable public API.
• Build reproducible wheel and normalized source-distribution artifacts with strict metadata, archive, executable-mode, checksum, Gitleaks, and separate clean-install verification.

Compatibility and boundaries:

• Supported target: CPython 3.11–3.14 on Linux and macOS. Windows is unsupported.
• Harness Workbench executes trusted commands and Python feature modules with the current user's permissions; it is not a security sandbox.
• The release is not published to PyPI. Install from these GitHub assets or a tagged clone.
• Live subject runs can require third-party clients, credentials, network access, and paid quota. The core tests and artifact verification are network-free.

The attached SHA256SUMS authenticates the wheel and normalized source archive. A release-final conformance record will be attached after the GitHub-hosted assets are downloaded and independently rechecked against those digests.
