Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. package manifest specifies @esbuild/linux-x64 name, version 0.28.1, linux OS, and x64 CPU requirements
  2. resolves path to bin/esbuild executable and reports matching version 0.28.1
  3. validates bin/esbuild executable format as 64-bit ELF binary with standard magic bytes
  4. esbuild binary transforms TypeScript code and JSX syntax to JavaScript
  5. esbuild binary bundles modular source files into a single bundle
