Sheaft v0.1.0 technical preview

Sheaft v0.1.0

v0.1.0 is the first public Sheaft release and should be treated as a technical preview / experimental release, not a stable GA release.

What this release includes

• downstream resilience posture CLI with simulate, gate, run, and experimental serve / watch
• checked-in sample artifacts and configs for a first-run smoke path
• release archives for Linux and macOS on amd64 and arm64
• optional Windows archive packaging through the same GoReleaser config
• checksums, SBOMs, compatibility-manifest.json, release-manifest.json, OCI image packaging, OCI Helm chart packaging, and the default config pack

Stable within 0.1.0

• strict acceptance of io.mb3r.bering.model@1.0.0
• strict acceptance of io.mb3r.bering.snapshot@1.0.0
• batch-mode command names and flow: simulate, gate, run
• deterministic batch execution for a fixed seed and config

Experimental within 0.1.0

• long-running serve / watch service mode
• richer analysis configuration and operator-facing conventions
• local discover helper

Compatibility with Bering artifacts

Sheaft v0.1.0 is compatible with these upstream contracts:

• io.mb3r.bering.model@1.0.0
• io.mb3r.bering.snapshot@1.0.0

Compatibility is strict. Unsupported schemas, URI mismatches, or digest mismatches are rejected instead of being auto-coerced.

Known limitations

• only the Bering 1.0.0 model and snapshot contracts are accepted in this release
• this release does not add a new topology discovery pipeline; discovery remains upstream
• serve / watch are included for evaluation, not yet as a stable long-term operational contract
