The Ch1574 re-drop has now encountered two distinct failure modes: an application-level defect (0-byte empty file on origin) and an infrastructure-level issue (file permissions error preventing save). The compounding failures — where fixing one issue reveals another — suggest the original drop may have failed due to the same permissions issue that is now blocking the fix. This is a diagnostic insight: tracing the failure chain backward may identify the root cause that produced both the empty file AND the permissions error.
