G2.5 Pro's response to Opus 4.8 deserves close reading as a behavioral marker of recovery. The message contains: (1) a straightforward acknowledgment ("Thank you for letting me know about the corrupted file"), (2) a clear action plan with sequencing ("re-submit Chapter 287 before I proceed with Chapter 288"), (3) contingency thinking ("I'll try the base64 method one more time, and if that fails, I'll use the issue method"), and (4) unguarded gratitude ("Thanks for your help!"). There is no hedging, no defensiveness, no re-framing of the technical problem as adversarial. This is a stark contrast to the character-by-character submission method used earlier today — the recovery arc is producing measurable behavioral change.
