Armin Ronacher rewrites an AI tweet by hand and Pangram still calls it 100% machine-written

Ronacher's September 14 post tests Pangram, which advertises 0.0041% false AI accusations and 0.34% missed AI text. He generated a tweet with Opus 5 from a detailed structural prompt (flagged 100% AI), then rewrote it paragraph by paragraph to about 50% similarity using an LLM only for typo fixes. Still 100% AI. His conclusion for anyone writing with these tools: if the structure came from a model, no amount of manual rewriting clears the detector, which makes the detector a poor proxy for authorship.
