+# test-convert-fence-model.sh — the converted-outputs eval must parse source
+# code fences the way lib.sh and GitHub do.
+#
+# The eval's Python model read fences only at column 0, while CommonMark (and
+# lib.sh's fence_open_p / fence_closes_p, aligned to it in #855 and #1028)
+# allows up to three spaces of indentation and does not constrain a closer by
+# the opener's indent. With an indented opening fence and a column-0 closer,
+# the model missed the opener and treated the closer as its own opener, so it
+# reported the following lines as a torn fenced block across SOUL.md/AGENTS.md
+# — a hard failure in the Check Tools workflow for an agent file that lint,
+# GitHub and convert_openclaw all handle correctly.
+#
+# Builds a throwaway repo around the real eval and one such fixture, then
+# requires the eval to validate it cleanly. `--update` keeps the check on a
+# fresh repo without a committed manifest.
+#
+# Usage: ./scripts/test-convert-fence-model.sh
