Sample
In @rollup/plugin-commonjs v28, strictRequires defaults to true, wrapping CommonJS modules in function closures so that conditional requires execute lazily rather than eagerly at bundle load time, and circular dependencies resolve in-progress exports.

Commonly assumed
Bundling CommonJS modules with Rollup statically hoists and eagerly executes all module top-level code on bundle import regardless of whether a require call is nested inside a function or conditional branch.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- assert @rollup/plugin-commonjs with default strictRequires wraps CommonJS modules in lazy function closures, preventing top-level side effects of conditionally required modules from executing at bundle evaluation time until the function is invoked
- assert setting strictRequires: false hoists all CommonJS requires to the bundle top-level, causing side effects of lazy requires to execute immediately upon module evaluation
- assert strictRequires: true resolves circular CommonJS dependencies at runtime by providing the in-progress exports object, whereas strictRequires: false leaves circular references uninitialized as undefined
- assert strictRequires accepts picomatch glob patterns to selectively wrap only targeted circular modules while hoisting all other CommonJS files
