nx_manga_rating_gate.nx -- REFEREE for mangagen MG24 (mr_rate_row) and MG32 (mr_depiction_legal). IN-PROCESS against nx_manga_rating_lib: the decision has ONE home, so the CLI and this gate cannot drift into two different answers. It proves the done-rules pre-declared on /compare/mangagen before the organ existed: MG24 -- a rating row bound to the ASSET at emit, never to the account; a family-tier viewer cannot be served an adult-rated asset, and an UNRATED asset is treated as GATED rather than safe. MG32 -- the adult invariant fails closed at CONSTRUCTION, not by policy. ANTI-VACUITY IS THE POINT. A guard that DENIES EVERYTHING passes every deny test ever written, so every refusal tooth below is PAIRED with a positive control that must be ALLOWED: T2 against T1, T12 against T11, T13 against T14. T10 requires the ladder to actually discriminate -- an implementation that mapped every rating to the gated area would satisfy T5, T8 and T9 and still be useless, and only T6, T7 and T10 refute it. T17 is a CROSS-IDENTITY: this lane must never grow its own copy of the adult age, so the gate asserts the imported WS_ADULT_AGE is still 18. If the character lane moves it, this gate says so. license_tier: ORIGINAL expect_exit: 0
