# Per-PR reviewer graph bundle.
#
# This is a TEMPLATE, not a live workflow. The `.yml.example` suffix means
# GitHub Actions does NOT register or run it — copy it to
# `.github/workflows/gortex-pr-review.yml` in your own repository to enable it.
#
# On every pull request it builds gortex, indexes the checked-out repository
# into the daemon, runs `gortex prs bundle <N>` to produce the reviewer graph
# bundle (changed files + graph-joined blast radius + PR-risk receipt + ranked
# reviewers), and uploads that bundle as a CI artifact. A reviewer (or a
# downstream agent) can then download one self-contained JSON file instead of
# re-deriving the impact from scratch.
#
# The daemon self-serves PR data from the auto-provided `GITHUB_TOKEN` (mapped
# to `GH_TOKEN`), so no extra secret configuration is needed.
