nx_manga_ocr_gate.nx

nx_manga_ocr_gate.nx -- REFEREE for MG22 (mo_text_regions). IN-PROCESS against nx_manga_ocr. THE FIXTURE IS PLANTED, NOT DECODED. Every ink map below is written by this gate at known coordinates, so the EXPECTED ANSWER IS EXACT rather than eyeballed -- no image decode, no GPU, no corpus, and the whole run is deterministic. A detector graded against a picture someone looked at is graded by an interpretation; this one is graded by arithmetic. ANTI-VACUITY IS THE POINT. The trivial wrong implementation returns ONE bounding box around all the ink and would satisfy any tooth that merely asks did-you-find-something. T3 requires TWO separated blocks to come back as TWO with their own bounds, and T6 requires two lines a SMALL gap apart to come back as ONE -- a detector that always splits fails T6, a detector that always merges fails T3, and no single wrong rule passes both. license_tier: ORIGINAL expect_exit: 0
