+# One-off. cmux-platform-production is taking over NEXT Cloud's CloudDO routes from cmux-api production
+# (the CloudDO move into cmux-platform) and needs the same JWT_PRIVATE_JWK and CLOUD_LINK_SIGNING_KEYS as
+# cmux-api production, plus a Freestyle key. The cmux-next-production environment is the only GitHub copy;
+# this job pipes what it holds (stdin, never logged) into the Worker's secrets. It writes only these three
+# names, only when the Worker lacks the name (it never overwrites one), and prints no value. A name the
+# environment does not hold is skipped with a notice. Same pattern as platform-dev-secrets.yml (#30461).
+# GitHub registers dispatch workflows only from the default branch (main), so this also runs on the
+# push that lands it on feat-cmux-next (path-filtered to this file). A follow-up drops the push trigger.
