Building

$3

You need to install Rust

Then, install wasm-pack

`bash
cargo install wasm-pack
`

Finally, do a clean install and build

`bash
npm ci && npm run build
`

$3

You can build the exact same bytecode using Docker, just be sure you're on a linux/amd64 host

`bash
docker compose up --build
`

Then check that all the files are the same using npm diff

`bash
npm diff
``

If the output is empty then the bytecode is the same as the one I commited

$3

Each time I release a new version on GitHub, the GitHub's CI clones the GitHub repository, reproduces the build, and throws an error if the NPM release is different. If a version is present on NPM but not on GitHub, do not use it!
