Build Compatibility Tests

These tests verify that published artifacts work across module systems.

Files

File	Target
tests/Builds/cjs.test.cjs	CommonJS runtime
tests/Builds/esm.test.mjs	ES Module runtime
tests/Builds/umd.test.cjs	UMD/global runtime
tests/Builds/umd.html	Manual browser UMD smoke page
tests/Builds/ts.test.ts	Type-level import usage check

What They Validate

• new ME() remains callable as proxy function.
• basic semantic write/read works after build.
• exports are correctly wired in each module format.
• UMD global export exists and is executable in a sandbox.

Run

node tests/Builds/cjs.test.cjs
node tests/Builds/esm.test.mjs
node tests/Builds/umd.test.cjs

or via gate:

npm run test:prebuild

Release Relevance

These tests protect the npm consumer surface:

• import consumers (modern tooling),
• require consumers (legacy Node),
• browser consumers (UMD script usage).
