nx_twincard_lib.nx -- THE TWIN CARD: one declared person or synth, every value on a declared axis with its SIDE, unit, method and source (aesthetictwin AT23, symbol tc_card_check, 2026-09-16). Operator: "a system that is more comprehensive than the illusion cards", then "minute variation between left and right ... down to the smallest unit ... each freckle or smaller is reproducible". An Illusion character card is a PNG carrying about a hundred unitless sliders and no provenance; this card is DATA (knowledge/twincard/<slug>.card) whose axes are declared in knowledge/twincard.axes (identity, body, soft tissue, skin, hair, eyes, ears, lips, teeth, hands, feet, body hair, nails) and, for the face, ARE the canon ids of knowledge/facecanon.conf -- one ruler for the face, never two. A PAIRED axis is recorded per side (L and R are two values, never one), an unpaired axis is C. Individual surface features (freckle, mole, scar, vein, tattoo, birthmark) are one row each in a declared body-surface region with permil chart coordinates, a diameter in mm100 and a CIELAB colour, so a freckle field is reproducible feature by feature. Every axis may name its RULER (the sovereign organ and symbol that measures it); the CLI censuses which rulers exist today, so the measurement investment is a number rather than a wish. Every row carries a METHOD (measured, observed, declared, generated) and a SOURCE, so the card reports what it knows and how; coverage, the method partition and the completed left-right pairs are numbers a page can print.

A canon band is a hypothesis under test, so a face value is never range-checked against it. Composes nx_refintake_lib for the row helpers (the intake is the card's media leg). LIB, no main. license_tier: ORIGINAL No hw writes (Rule 26).
