## About

# Project Vendor Boundary

This is a composable overlay, not a standalone workflow.
Use alongside the repo's implementation skill when work touches vendored
dependencies or their integration boundary.

## When to use

The change involves vendored third-party code, the boundary between app-owned
and vendored code, or dependency integration (subtrees, vendor directories,
copied sources).

## Not for

App-owned code that does not touch vendor boundaries (use the implementation
skill directly), or release/packaging concerns (use **project-release-maintainer**).

## Rules

- prefer app-side integration changes before editing vendored code
- treat vendored code as subtree/vendor content, not normal project code
- keep notices, provenance, upstream version/source, local patch rationale, and
  install rules aligned with vendor changes
- prefer adapter or wrapper changes in app-owned code before patching vendored
  sources; patch vendor code only when the seam cannot reasonably absorb the
  change
- avoid unrelated churn inside vendor trees
