### EXPERIMENT 60B.66 — LIVE DECISION-CLOSURE REGRESSION (PASS)
**Date:** 2026-08-14
**Branch:** `feature/decision-closure-integration-v0.43`
**Experiment commit:** bce05f7 feat(reasoning): integrate explicit decision-sufficiency closure (60B.64)
**Result:** A — LIVE REASONING THREAD CLOSED
The committed 60B.64 deterministic closure rule was verified live against the exact negative customer-signing case from 60B.56.
Key outcomes:
- Decision `n_product_launch_decision` resolved unknown→resolved (was KEPT OPEN in 60B.56)
- `finalActiveUnknownNodeId = null`, `finalSelectedQuestion = null` (both were non-null in 60B.56)
- Customer factor resolves in place with negative meaning preserved
- Zero addedNodes, zero addedEdges
- Decision identity preserved; both options preserved
Pre-refactor behavioural baseline established.
Next structural task may be zero-semantic-change decision-sufficiency extraction.
