[T2] header + encounter-0 field extraction (whole-key parser on sub-ranges). [T3] validation: complete campaign -> 0 missing; header w/o quest + an encounter w/o kind/goal -> 3 missing (NEG-CONTROL). [T4] GM brief emit equals the expected string exactly. [T5] image-prompt seed emit equals the expected string exactly. [T6] CONTINUITY time tooth: sound timeline -> 0; time 3 then 2 -> 1 (NEG). [T7] CONTINUITY transit tooth: moves with transit -> 0; same location w/o transit -> 0 (no false positive); move w/o transit = TELEPORT -> 1 (NEG). [T8] whole-key: the word goal inside a value does NOT satisfy the goal key. Evidence -> stdout + knowledge/status/campaign_gate.log. Exit 0 GREEN / 1 RED. Sovereign x86_64. license_tier: ORIGINAL
