 Migration policy (Phase 1):
-- Every existing ``from rich import print as rprint`` becomes
+- A ``from rich import print as rprint`` whose output is a *log or hint* becomes
   ``from comfy_cli.output import rprint``. The shim suppresses stdout in JSON
   mode (redirecting to stderr so logs are still visible) and is byte-identical
   to rprint in pretty mode.
+- A call site that prints a command's *primary result* must NOT be migrated
+  until that command emits a ``renderer.emit(...)`` envelope. ``resolve()``
+  selects JSON mode whenever stdout is not a TTY, so migrating a result path
+  first would route the result to stderr and leave stdout empty -- e.g.
+  ``comfy generate ... > out.txt`` would write an empty file. The known
+  un-migrated result paths are ``command/generate/app.py``,
+  ``command/generate/output.py`` and ``command/pr_command.py``; each carries an
+  in-file comment saying so.
 - Commands that produce a structured result emit a final envelope with
   ``renderer.emit(data)``. This is the *only* thing on stdout in JSON mode.
 - Streaming commands emit ``renderer.event(type, **fields)`` events; one
