nx_number_envelope_gate.nx

nx_number_envelope_gate.nx -- CE6 (codeeffectiveness ce_number_envelope): the envelope primitive in the gate base class publishes a figure ONLY with n, an interval containing it and a null control, and refuses every other shape BY NAME with its own code. In-process: the subject is nx_gate_verdict.nx itself, so this gate is RED the moment the primitive stops discriminating (a primitive that publishes everything passes every well-formed tooth and fails the bite). The fixture figures are the estate's own scorer numbers (419 permil on all 365 judged queries) so the demo lines read like a real emit, and every expected code was decided before the run. exit: 0 GREEN . 1 RED . 3 SKIP license_tier: ORIGINAL No hw writes.
