nx_photomark_gate.nx

nx_photomark_gate.nx -- the referee for nx_photomark_lib (aesthetictwin AT4 / AT23, 2026-09-16). In-process on a synthetic frontal face (no network, no decoder, no real card): a skin ellipse on a non-skin non-dark field, two dark lens-shaped eyes whose canthi are PLANTED with ASYMMETRIC tilts (right 85, left 57 deg10), a red mouth with a dark stomion line splitting it 10 over 14. The ruler must find the face box, both eye pairs of canthi within pixels, both tilts within tolerance with the asymmetry preserved, the two canon ratios the planted geometry implies, the stomion row and the lip ratio; a field with no face is UNMEASURED, a face without eyes is UNMEASURED, and a MIRRORED fixture swaps the sides while each tilt keeps its sign. The card write appends five measured rows once and refuses the second time. The file door (AT33): the same fixture encoded through the sovereign PNG writer and read back through pm_landmarks_file_auto must reproduce the in-process numbers exactly and announce the PNG codec; a non-image file is a named decode refusal and an absent file is unreadable. AT44 (2026-09-18): the mouth's five landmarks on the planted lines; DECOYS that must not move them (a black chin fold wider and darker than the seam, a shadow redder than the lip between them); a mouth with no seam and a seam shorter than a lip refused by name; a one-pixel lash wing followed to its tip past the blob with a decoy dot one pixel beyond the fissure's bridge left alone; a fissure run onto its window's side refused as PINNED; the referee scoring the planted mouth (ruler and anchored) FOUND and a mouth shifted 40 px PLACED-OFF. Each of these teeth was bitten by a mutant of the lib (see the board's AT44 log). Values are printed with gv_kv. license_tier: ORIGINAL No hw writes (Rule 26).
