RuDS utilities, transforms, and macros run in a sandbox with explicit project-scoped capabilities under bds. Start with the complete API reference, canonical types, and runnable examples. Portable method signatures match bDS2 contract 0.4.0; RuDS-only helpers are marked as extensions.

api.json is the sole method/type manifest. Regenerate the reference and completion data with:

cargo run -p bds-core --example generate_scripting_docs

The core scripting tests verify the Allium capability names, runtime tables, generated files, sandbox, failure values, project scoping, examples, and the frozen bDS2 signature baseline in bds2-core-signatures.json together.
