+# OnTrack pull-request review policy
+
+The required status context `ontrack/review-policy` passes when the current pull
+request head has either:
+
+- one approval from a current `ontrack-leads` member; or
+- two approvals from distinct current `ontrack-contributors` members.
+
+Approvals from the pull-request author, bots, stale commits, dismissed reviews,
+or reviewers whose latest actionable review requests changes do not count.
+
+## Security model
+
+`ontrack-review-policy-signal.yml` is unprivileged and never checks out pull-request
+code. A completed signal wakes `ontrack-review-policy.yml` through `workflow_run`.
+The evaluator workflow checks out only this directory from the protected default
+branch, then mints a short-lived token for the organization-owned GitHub App.
+
+The App is installed only on the three OnTrack Doubtfire repositories and has:
+
+- organization Members: read;
+- repository Metadata: read (mandatory);
+- repository Pull requests: read; and
+- repository Commit statuses: write.
+
+The App has no contents, workflow, administration, merge, or webhook permission.
+Its private key is held in `ONTRACK_REVIEW_APP_PRIVATE_KEY` in the
+`ontrack-review-policy` environment, which only permits the protected `11.0.x`
+branch. Its numeric App ID is held in `ONTRACK_REVIEW_APP_ID`.
+
+The evaluator reports on the pull-request head commit. GitHub gates on the test merge
+commit whenever that commit carries a status and only falls back to the head when it
+carries none, so reporting on the test merge commit would move the merge gate onto a
+commit that carries none of this repository's other checks. The head is also stable,
+where the test merge commit is recomputed every time the base branch moves.
+A five-minute reconciliation covers team membership and base-branch changes that
+do not emit a pull-request review event. Unchanged results are not republished,
+which avoids GitHub's per-commit status limit.
+
+## Ruleset integration
+
+Keep the native one-overall-approval rule, stale-review dismissal, and conversation
+resolution. Require `ontrack/review-policy` with the OnTrack Review Policy App as
+its expected source. Remove the native `ontrack-leads` required-reviewer entry only
+after the App status has been observed and made required; otherwise GitHub combines
+the native team rules with AND semantics.
+
+Changes to any workflow, the evaluator, or CODEOWNERS should continue to require
+one `ontrack-leads` approval through a path-specific native reviewer rule. This is
+necessary because any default-branch workflow could otherwise reference the App's
+environment secret.
