+# CAMARA Release Automation — Regression (canary)
+#
+# Sibling to validation-regression.yml. Exercises the release-automation-reusable.yml
+# workflow on camaraproject/ReleaseTest via a /create-snapshot + /discard-snapshot
+# round-trip, catching runtime bugs in the RA workflow and shared actions
+# that the Validation Regression canary cannot reach.
+#
+# Round-trip only — never merges the Release Review PR, never creates a
+# draft build, never calls /publish-release. No real tags or releases
+# are produced. Full manual E2E remains the gate for publish-side changes
+# before @v1-rc moves.
+#
+# Cross-repo access is provided by a short-lived camara-validation
+# GitHub App installation token scoped to camaraproject/ReleaseTest.
+# Permissions used: issues:write (post slash-command comment),
+# actions:write (poll caller runs), pull_requests:write (verify Release
+# Review PR presence). The App has no contents:write — and none is needed.
+# The default GITHUB_TOKEN is only used for the initial checkout.
