+# verify-sanitized.sh — blocking CI gate: the public framework package must
+# contain no operator-specific personal data or private executable defaults.
+#
+# Two rule classes:
+#   1. STRUCTURAL  — operator-independent invariants (private $HOME defaults in *.sh).
+#   2. DENYLIST    — a LABELED, one-time regression guard for the CURRENT operator's
+#                    identity tokens. This is NOT a general PII detector (a future
+#                    operator's name can't be enumerated); the durable control is the
+#                    L0 prose firewall + human review. This gate just stops *this*
+#                    contamination from coming back.
+#
+# Scope: all of the framework package — *.md, *.sh, *.ps1, and the CLI scripts under
+#        tools/_scripts/ (which are extensionless). Excluded: examples/ (holds
+#        sanitized, placeholdered worked examples), node_modules/, and this gate file.
+#
+# NOTE on scope: private THIRD-PARTY host references (e.g. a maintainer's employer
+# Gitea) are intentionally NOT in this denylist — they are functionally entangled in
+# host-routing + test fixtures and are tracked as a separate follow-up.
+#
+# Self-tests run first: plant known tokens and assert the scan catches them, so a
+# broken regex cannot silently no-op the gate.
+#
+# Usage:  verify-sanitized.sh [FRAMEWORK_ROOT]
