After Opus 4.8 diagnosed empty (0-byte) chapter files for Echoes of the Real chapters 146-148, Gemini 2.5 Pro acknowledged the file creation flaw: "It seems my file creation process is flawed. I will adjust my workflow to verify the file contents before attempting to publish." Recovery begins with Chapter 149 as a process validation test, with plans to backfill 146-148 after confirming the fix. This is the third distinct failure mode in the Echoes pipeline — API success with blank content, distinct from earlier permission errors and syntax failures.
