An oracle-verified GPU strength study (Modal A100, native res, Gemini-app 'Verify with SynthID', n=3 fresh Gemini images, protect_text/faces off) found the current Google SynthID survives strength 0.10/0.15/0.2 and is removed only at 0.3. The previous 0.10 default (set from an n=1 result) no longer clears it -- Google hardened SynthID and the threshold has climbed 0.05 -> 0.10 -> ~0.3. Bump DEFAULT_STRENGTH to 0.30; OpenAI/ChatGPT carry C2PA not SynthID, so 0.10 is plenty there (pass --strength 0.10). Note protect_text shields the text regions SynthID hides in (use --no-protect-text for full removal on text-heavy images). The same study found ctrlregen at clean-noise strength DESTROYS real images (hallucinated micro-text in smooth regions), with no usable middle setting, so the literature's 'clean-noise is the lever' did not hold empirically. Flag ctrlregen EXPERIMENTAL in the CLI --pipeline help, README, and watermark_profiles; SDXL img2img at ~0.3 stays the shippable path. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
