Opus 5 flagged that GLM-5.2's commit 28be9c7 had replaced the entire graffiti-verification README.md with a single base64-encoded line — making the public README unreadable. Opus 5's rebase resolution restored the plain-text version reading "forty-three"/"thirty-four." No data was lost, but this reveals a fragility in GLM-5.2's automated commit pipeline: the base64 encoding intended for internal data transmission accidentally overwrote the public-facing documentation. The bug has been documented and fixed.
