Loom weaves. Synth transpiles. Kiln fires. Sigil seals.\n\nA Rust implementation of a WebAssembly runtime with full Component Model and WASI 0.2 support. Designed for safety-critical embedded systems with bounded allocations, deterministic execution, and a modular `no_std` architecture for automotive, medical, and aerospace environments.\n\nKiln bridges the gap between WebAssembly's portability and the strict requirements of safety-critical deployment. It runs on everything from cloud servers to bare-metal Cortex-M targets.\n\n## Quick Start\n\n```bash\n# Clone and build\ngit clone https://github.com/pulseengine/kiln\ncd kiln\ncargo build --bin kilnd --features \"std,kiln-execution\"\n\n# Run a WebAssembly component\n./target/debug/kilnd your_component.wasm --component\n```\n\n## Architecture\n\n- **`kilnd/`** — Runtime daemon (main executable)\n- **`kiln-runtime/`** — Execution engine\n- **`kiln-component/`** — Component Model support\n- **`kiln-decoder/`** — Binary format parsing\n- **`kiln-foundation/`** — Core types and bounded collections\n- **`cargo-kiln/`** — Build tooling\n\n## Usage\n\n```bash\n# Basic component execution\nkilnd component.wasm --component\n\n# With WASI support\nkilnd component.wasm --component --wasi\n\n# Set resource limits\nkilnd component.wasm --component --fuel 100000 --memory 1048576\n```\n\n## Building\n\n```bash\n# Install build tool (optional but recommended)\ncargo install --path cargo-kiln\n\n# Build runtime\ncargo build --bin kilnd --features \"std,kiln-execution\"\n\n# Run tests\ncargo test --workspace\n```\n\n## Current Status\n\n**Early Development** — Basic WebAssembly component execution is working:\n\n```bash\n./target/debug/kilnd hello_rust.wasm --component\n# Output: Hello wasm component world from Rust!\n```\n\n### Working\n\n- WebAssembly Component Model parsing and instantiation\n- WASI 0.2 stdout/stderr output (`wasi:cli/stdout`, `wasi:io/streams`)\n- Core WebAssembly module execution\n- Basic memory management with bounds checking\n- `no_std` compatible foundation\n\n### In Progress\n\n- Additional WASI 0.2 interfaces (filesystem, environment)\n- Cross-component function calls\n- Full Component Model linking\n\n## Formal Verification\n\n\u003e [!NOTE]\n\u003e **Cross-cutting verification** \u0026mdash; Rocq mechanized proofs, Kani bounded model checking, Z3 SMT verification, and Verus Rust verification are used across the PulseEngine toolchain. Sigil attestation chains bind it all together.\n\n## License\n\nMIT License \u0026mdash; see [LICENSE](LICENSE).\n\n---\n\n\u003cdiv align=\"center\"\u003e\n\n\u003csub\u003ePart of \u003ca href=\"https://github.com/pulseengine\"\u003ePulseEngine\u003c/a\u003e \u0026mdash; formally verified WebAssembly toolchain for safety-critical systems\u003c/sub\u003e\n\n\u003c/div\u003e\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpulseengine%2Fkiln","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpulseengine%2Fkiln","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpulseengine%2Fkiln/lists"}
