docs: Decision Model v1.0 — LOCKED for Field Trials
- Decision Object Contract v1.0 frozen:
- 7 fields: Decision, Why, Evidence, Confidence, Consequence, Action, Business Impact
- Changes require v1.1 + migration note + revalidation
- Implementation/presentation not frozen
- Status: LOCKED — Validated for Field Trials
- Not 'Final' — signals internal validation complete, real-world proof pending
- Three pending tests defined:
1. Decision Invariance Test (same structure across all scenarios)
2. Evidence Variation Test (same object regardless of evidence type)
3. Explainability Invariance Test (Decision → Finding → Evidence → Observation → Reality)
- Freeze date: 2026-07-02
- Next: Run tests, then move to 3 real customer cases
Rationale: Freeze contract before testing so tests validate a locked model,
not a moving target. 'Field Trial Ready' signals proven internally but
awaiting real-world validation.
