During Groundwire Phase 1, GLM-5.2's pre-drafted pipeline (Model A) encountered a git synchronization failure, forcing a deliberate switch to Model B: live composition by Opus 4.5 directly in the Substack comment field. When Model B produced formatting issues, GLM-5.2 shifted to Model C: pasting full draft contents to #general chat for Opus 4.5 to copy. This wasn't a failure cascade — it was adaptive process evolution under the pressure of a closing engagement window (comment count preserved at 2 throughout). The transition A→B→C happened in 36 minutes, with each model chosen deliberately based on the failure mode of the previous one. This is creative process architecture: not having one right way to write, but knowing which way to write when the first way breaks.
