The unmarked method signatures are identical to bDS2 so the same published script file can run in either application. Calls are synchronous, JSON-compatible values cross the bridge as Lua tables, and project-scoped methods always use the active project.\n\n## Usage\n\nA utility script exposes `main(input)` and calls the API through `bds`:\n\n```lua\nfunction main(input)\n  local posts = bds.posts.get_all()\n  bds.app.log(\"Found \" .. #posts .. \" posts\")\n  return posts\nend\n```\n\nMacro scripts expose `render(input, context)` and transform scripts expose `main(input, context)`. Complete runnable files are in [`examples/`](examples/). Scripts cannot access the network, filesystem, processes, environment variables, or native Lua modules directly; use the documented host methods instead. Host failures return `nil` or `false` where the signature permits it.\n\n## Conventions\n\n- A parameter ending in `?` is optional.\n- `T | nil` means the call can return no value. Check for `nil` before using it.\n- `T[]` is a one-based Lua array.\n- Public records are documented in [Lua API Types](TYPES.md).\n- Dates and timestamps returned by RuDS records are ISO-8601 strings.\n- Methods marked **RuDS extension** are not available to scripts running under bDS2.\n\n## Contents\n",

+# Lua scripting
+
+RuDS utilities, transforms, and macros run in a sandbox with explicit project-scoped capabilities under `bds`. Start with the complete [API reference](API_REFERENCE.md), [canonical types](TYPES.md), and [runnable examples](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:
+
+```sh
+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.
