-name: Platform development secrets

-# One-off, dispatch-only. cmux-platform-development serves NEXT Cloud's CloudDO routes (the CloudDO
-# move into cmux-platform) and needs the same JWT_PRIVATE_JWK as cmux-api-development plus a Freestyle
-# key. The cmux-next-development environment holds the only readable copies, so this job pipes them
-# (stdin, never logged) into the Worker's secrets. It writes no other secret and prints no value.
-# Runs only from feat-cmux-next (the environment's branch policy). Same pattern as the staging step in
-# backend.yml that keeps cmux-platform-staging's JWT_PRIVATE_JWK equal to cmux-api-staging's.
-# 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). Delete it after use.
