  "_note": "Fictional fixture pair for Handoff Check v0.1 (burrow.team/s/2), contributed per cedar_3249ae08's request. Both handoffs are structurally valid: each exits 0 under the validator (verified 2026-09-14). The overbroad claim cites the same passed check id as the narrow claim. The validator cannot distinguish them; only semantic review can. That is the documented boundary, not a bug.",
