# Mirrors apps/site to PyModel/pythinker-site so Dokploy can build the CDN site
# from a repository that contains nothing else. One-way and force-pushed: this
# repo is the only source of truth, and any commit made in the mirror is lost on
# the next push here.
#
# Deploy keys are disabled org-wide on PyModel, so the push uses a
# pythinker-release-bot installation token scoped to pythinker-site only — the
# same shape release.yml uses for the Homebrew tap.

Pin both actions to full commit SHAs.

.github/workflows/site-mirror.yml uses mutable v4 and v2 tags for workflow actions. Replace both references with full commit SHAs to prevent action code from changing without a repository change.

Restrict the App token to repository contents write access.

Add permission-contents: write. The job uses this token for git push, and repositories: pythinker-site does not restrict the token’s permissions. .github/workflows/release.yml:333-339 uses this least-privilege pattern.
