The resolution curve's 0.154 top left the 4.33 MP CJK-sign fixture SynthID-detected x3 in Gemini on the full production path (visible stage -> qwen-zimage seed 0 -> resize-back -> metadata strip), with a valid pixel-identical stripped control in the same session (2026-08-18). Google-provenance content now resolves to the flat QWEN_ZIMAGE_GOOGLE_STRENGTH 0.30 floor instead of the area curve - anchors at 0.30 measured clean in Gemini on two fixtures (CJK sign + 18-face) at 3/3 checks across two work accounts, and stayed clean under the vae-glyphs donor layer. openai/unknown content keeps the curve; an explicit strength still wins.
