Project Vendor Boundary

This is a composable project overlay. Add matching implementation guidance when the work requires language-specific code judgment.

For review, inspect provenance, local patches, and integration behavior without updating, fetching, or replacing the vendor tree. During implementation, preserve pre-existing local changes and apply only the requested integration or update.

When to use

The change involves checked-in third-party source, a subtree or submodule, a vendor directory, copied sources, a local vendor patch, or the app-owned adapter around that material.
