+# Centralized roadmap sweeper: adds recently-touched issues & PRs from every
+# owned repo (except son-shared) into the Hyperpolymath Master Roadmap (#35).
+#
+# WHY centralized (one workflow, one secret) instead of a per-repo workflow:
+#   - the PAT secret lives in exactly ONE repo (this one), not ~250 copies;
+#   - one file to maintain, one place to rotate the token.
+# GITHUB_TOKEN is scoped to this repo only and cannot read other repos, so all
+# cross-repo reads use the classic PAT (ADD_TO_PROJECT_PAT: scopes project +
+# public_repo). Private repos are therefore NOT covered yet — widening the PAT
+# to `repo` (one secret, one place) is a deliberate later step.
