Manifest SHA-256: 1502b03262905663e90423d3c124634458fcdec46fe64801328ea5dec143866e. The recorded Git revision identifies the containing repository; the manifest and entry-point hashes identify this working-tree snapshot.

Integration

Use the package root above from an authorized source checkout. Preserve sibling dependencies and their version/feature requirements. Install the runtime and compile the selected package before using its generated artifacts. The task guide describes configuration, trust boundaries, and error behavior. Test/conformance and deployment packages are supporting tools, not interchangeable production identity providers.

Exported entry points

The declarations below are extracted from the named entry files. This is a navigable source reference, not compiler-generated documentation of every transitive module. Feature gates and runtime requirements still apply. Private implementation files are not promoted to public APIs merely because they contain a public declaration.
