4. The Four-Pillar Quadrilateral & Non-Claims

Every contract in simplex-normal-forms is evaluated against the Four-Pillar Quadrilateral defined in contracts/_golden_nfs/standard.yaml:

Pillar	Requirement	Contract Specification for nf.experimental.gauge
Pillar I: Excludes Anomaly	Name and eliminate a specific class of data or state defects.	gauge drift
Pillar II: Preserves Invariant	State the structural invariant and protected skeleton preserved across transitions.	Invariant: protected_skeleton_must_be_declared_before_transport Protected Skeleton: ['source_regime', 'target_regime', 'protected_skeleton', 'allowed_gauge_transformations', 'loss_ledger_policy']
Pillar III: Lossless Reconstruction	State the non-loss reconstruction operator (join, direct sum, pullback, or replay).	Lossless reconstruction under declared projection, direct sum, or pullback operators.
Pillar IV: Syntactic Decidability	State how conformance is decided from declared constraints without unbudgeted scans.	Decidable from declared schema and witness metadata within bounded evaluation budgets.

Explicit Non-Claims (certified_implies_authorized: false)

• does not make quantum market legal or physical domain claims part of the core taxonomy
• does not promote experimental data regimes to normal forms

5. Operational Verification & Terminal Routing

5.1 Required Declarations

• source_regime
• target_regime
• protected_skeleton
• allowed_gauge_transformations
• loss_ledger_policy

5.2 Required Evidence

• transformation_trace
• preserved_skeleton_witness
• loss_ledger_when_distinctions_are_erased

5.3 Validation Criteria

Criterion ID	Name	Condition
criterion	Check	protected_skeleton_must_be_declared_before_transport
criterion	Check	erased_distinctions_require_loss_ledger
criterion	Check	experimental_claims_must_remain_quarantined

5.4 Terminal Route Map

Every evaluation terminates in a declared local route mapped to a canonical terminal in standard.yaml:

Local Terminal Route	Canonical Terminal
Preserve	Preserve
Lift	Lift
Escalate	Escalate
Unsupported	Unsupported
ClosureFailure	ClosureFailure
BudgetUnknown	BudgetUnknown
Quarantine	Quarantine
Refuse	Refuse

5.5 Declared Failure Modes

All defects route explicitly through the Terminal Route Map above.

6. Epistemic Claim Hygiene Quadrant

In accordance with the repository's epistemic claim discipline:

1. What it supports:
   • Supports syntactic and operational checking of nf.experimental.gauge (XGauge) against its declared schema, boundary constraints, and witness obligations in this model.
   • Supports deterministic terminal routing (Preserve, Lift, Escalate, Unsupported) when required declarations or invariants fail.
2. What it does not support:
   • Does not confer operational authority (AuthorityEffect: None, certified_implies_authorized: false).
   • Does not claim semantic truth of undeclared external processes or unverified upstream inputs beyond the declaredprotected skeleton.
3. The narrowest defensible claim:
   • Within the declared substrate at_rest, this contract enforces that gauge drift is either excluded under protected_skeleton_must_be_declared_before_transport or routed to an explicit refusal/recovery terminal.
4. The next test needed:
   • Property-based falsification and mutation testing across boundary edge cases and composed multi-step pipelines for nf.experimental.gauge.
