BSSG: An Evidence-Independent Control Plane for Bounded Artificial Agency

BSSG (Bounded Structural Safety Gate) v0.1 -- paper and carried artifact bundle. The paper reports three contributions: (1) a five-conjunct evidence-independent control plane for bounding the consequential effects of autonomous AI agents; (2) a 34-instance defect trajectory documenting producer blind-spot recurrence under multi-model adversarial audit, closed by a structural class fix confirmed by five vendor families; and (3) the multi-model adversarial council as a verification methodology. No effectiveness claim is made. Artifact state: 345 tests OK, 176/176 counterexamples GREEN, bounded exhaustive enumeration PASS (11,110 schedules), verifier 12 PASS / 2 WARN / 0 FAIL, two-family carry (Grok 4 / xAI and Kimi K3 / Moonshot). Bundle contains the pass-37 reference gate (Python, stdlib only), 6 JSON schemas, 176-counterexample corpus, bounded enumeration checker, execution-bound attestation harness, 13-gate verifier, full audit history (30 files), carry evidence, and methodology corpus.
