  "_doc": "Demo serving envelope (ADR-0184 hybrid verification demo). The ONLY problems the demo may serve as verified: each entry was audited against its lane gold at pin time, and a live run must reproduce the pinned derivation trace byte-for-byte (derivation_trace_sha) before the answer is served. A pool commit without an authorized entry is refused (outside_demo_serving_envelope): measured on the 937-problem ADR-0184 equivalence corpus, 118 of the off-serving pool's 231 commits disagree with lane gold, so a bare pool commit is not a serving license. Adding an entry requires: lane gold provenance, a reviewed diff, and tests/test_claude_hybrid_verification_demo.py green (it re-audits every entry against the named lane file).",
