description	Update GitHub Actions node module cache version when dependencies change. Use when modifying package.json, yarn.lock, adding/removing/updating npm packages, or changing node dependencies.

Node Module Cache Update

When node dependencies are added, removed, or updated in this monorepo, the GitHub Actions cache must be invalidated to ensure CI builds use the correct dependencies.

When to Update

Update the cache version when:

• Adding new dependencies to any package.json
• Removing dependencies from any package.json
• Updating dependency versions (including pinning versions)
• Modifying yarn.lock

How to Update

1. Open .github/workflows/celo-monorepo.yml
2. Find the NODE_MODULE_CACHE_VERSION environment variable (around line 27)
3. Increment the version number by 1

env:
  # Increment these to force cache rebuilding
  NODE_MODULE_CACHE_VERSION: 10  # <-- Increment this number

Why This Matters

GitHub Actions caches node_modules based on this version number combined with yarn.lock hash. If you change dependencies but don't increment the cache version, CI may:

• Use stale cached dependencies
• Fail with missing module errors
• Have inconsistent behavior between local and CI builds
