Pin wasmtime main branch at cf1389857275c262a9157d157f4ea90b6b32c4c5 (2026-03-13) for reproducible source builds with component-model-async. The wasip3-prototyping branch was merged into main. Also adds vendor/wasmtime-async to .gitignore. Refs #60 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Rewrites the script from a validation-only tool into a full clone-and-build pipeline with --clone, --build, --verify, --clean flags - Pins to wasmtime release-41.0.0 branch (SHA d938a9df, rustc >= 1.90.0) - Includes --verify mode with inline WAT component compilation test - Adds docs/wasi-03-api-surface.md documenting WASI 0.3 async interfaces Refs #60 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Adds a --test flag that validates the source-built wasmtime binary: - Binary exists and reports version - Compiles a component with canonical ABI (cabi_realloc, exports) - Runs the component (validates instantiation) - Checks component-model-async feature availability Refs #60 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Create async-echo-handler fixture with WIT bindings for integration tests - Add WIT directory to rust-async-handler fixture (was missing, causing build failures) - Fix integration_threading.rs to pass ShimConfig::default() to WarpGridEngine::new() (signature changed when ShimConfig was introduced) Closes #60 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
