+# The wall lives in readme-contributors as a reusable workflow and is written
+# straight to main after every merge, with no separate pull request. The
+# organisation profile keeps its README at profile/README.md, so that is the
+# file the wall fills.
+#
+# This used to be a copy of the job, and every run since 7 September failed:
+# its git add named .github/contributors.svg, which html format never writes,
+# so the step died with exit 128 before it could commit; and it pushed to a
+# protected main with the workflow token, which the ruleset refuses. The
+# profile's wall stayed empty.
+#
+# main is protected, so the wall pushes through the write deploy key stored as
+# CONTRIBUTORS_DEPLOY_KEY. `secrets: inherit` hands it over.
