# AI Agent Notes

## Kotlin/Wasm generation guardrails
- Avoid creating suspend lambdas for compiler runtime statements. Prefer explicit `object : Statement()` with `override suspend fun execute(...)`.
- Do not use `statement { ... }` or other inline suspend lambdas in compiler hot paths (e.g., parsing/var declarations, initializer thunks).
- If you need a wrapper for delegated properties, check for `getValue` explicitly and return a concrete `Statement` object when missing; avoid `onNotFoundResult` lambdas.
- If wasmJs browser tests hang, first run `:lynglib:wasmJsNodeTest` and look for wasm compilation errors; hangs usually mean module instantiation failed.
- Do not increase test timeouts to mask wasm generation errors; fix the invalid IR instead.

## Type inference notes (notes/type_system_spec.md)
- Nullability is Kotlin-style: `T` non-null, `T?` nullable, `!!` asserts non-null.
- `void` is a singleton of class `Void` (syntax sugar for return type).
- Object member access requires explicit cast; remove `inspect` from Object and use `toInspectString()` instead.
- Do not reintroduce bytecode fallback opcodes (e.g., `GET_NAME`, `EVAL_*`, `CALL_FALLBACK`) or runtime name-resolution fallbacks; all symbol resolution must stay compile-time only.
