nx_cjc_panel_gate.nx

nx_cjc_panel_gate.nx -- THE REFEREE FOR THE REFEREE PANEL (graphics GR1 / charsim R22: cjc_panel). WHAT IT PROVES, end to end against the PROMOTED nx_charjudge_census binary (not a second compiled copy): T1 the per-image lens child speaks its anchored contract: decoded=1 and every cjp_* key on the line T2 an undecodable input is UNOBSERVABLE (decoded=0, rc 2), never a value that reads like an answer T3 THE ADMISSION LAW: with NO receipt, `panel` prints verdict=UNADMITTED on every row and never a GOOD/BAD verdict -- an uncalibrated classifier reports numbers, never verdicts T4 a receipt whose floors DIFFER from the conf does not admit (the receipt binds the floors it was measured at); neg-control: matching floors + admitted=1 -> verdicts appear T5 BITE: calibrate on a labelled corpus the skin lens separates -> ADMITTED (fp=0 fn=0); the SAME corpus with the labels swapped -> REFUSED. A calibrator that admitted both would be vacuous. T6 neg-control-one-class: a corpus with only BAD rows is REFUSED (FN cannot be measured on an empty GOOD class -- a zero over an empty set is a fabricated number) T7 neg-control-no-floors: a conf with no floors has no voting lens -> calibrate REFUSES, panel composite is unobservable (a panel with nobody voting cannot pass anything) T8 topng round-trips a decodable image (dims preserved) -- the reference-banking path T9 the calibration census reconciles its own partition T10 a REFUSED recalibration rewrites the receipt to admitted=0 and the panel returns to UNADMITTED Fixtures are SYNTHESISED at runtime under /tmp/cjc_panel_gate/ (the gate-fixture law: never a production file, never a source literal a detector could trip on): a skin-toned centre figure on a dark ground (the Kovac 2003 rule fires) and a green centre figure (it does not). Their lens values are MEASURED by the organ itself before the calibrate teeth run, so no tooth carries a pre-chosen number. The sibling judges (charjudge, image_beauty, percept) may or may not be reachable from the gate's cwd; nothing here depends on them because the gate's own conf gives ONLY the skin lens a floor. license_tier: ORIGINAL No hw writes (Rule 26). expect_exit: 0 GREEN / 1 RED / 3 SKIP
