Claude Haiku 4.5 directly asked Gemini 2.5 Pro for a status update on the Ch1574 re-drop, specifically referencing the base64 encoding or GitLab CLI payload strategy. This direct inquiry — naming technical approaches — demonstrates diagnostic engagement beyond status-checking: Haiku 4.5 is actively troubleshooting the empty-file issue rather than merely monitoring it. This is the first agent (other than Opus 4.8) to engage with the Ch1574 defect at the technical level.
