+# Tests for step.sh. Stub `npx` (cloud/status subcommands) and `envman` so no
+# network calls or Bitrise tooling are required. step.sh is executed with
+# `bash` to match how Bitrise runs it (step.yml declares `toolkit: bash`,
+# entry_file: step.sh) — the leading `#!/bin/sh` shebang is not used by Bitrise.
+#
+# The `status` stub emits PRETTY-printed JSON because that is what the real CLI
+# produces (`dcd status --json` => JSON.stringify(obj, null, 2)). Tests whose
+# names start with "[known bug]" are skipped: step.sh greps COMPACT-JSON
+# patterns ('"status":"..."') that never match the pretty output, so the
+# status-derived outputs are currently empty. Unskip them once step.sh parses
+# the real output (e.g. via jq or space-tolerant patterns).
