Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
source-diff encoded-string-file:vendor/js-component-bindgen-component.js AI (source-diff): Base64-embedded wasm modules in generated vendor bindings, not payload obfuscation. ai
source-diff encoded-string-file:vendor/wasm-tools.js AI (source-diff): Same base64-wasm pattern in vendor bindgen output. ai
npm-metadata bundled-binaries AI (npm-metadata): Vendor wasm-tools/bindgen compiled artifacts are the package's stated function. ai
phantom-deps phantom-dep:binaryen AI (phantom-deps): Used via build tooling/config, not direct import. ai
phantom-deps phantom-dep:@bytecodealliance/preview3-shim AI (phantom-deps): Same-org sibling dependency, expected pattern. ai
