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.epistemic.efnf
Pillar I: Excludes Anomaly	Name and eliminate a specific class of data or state defects.	external state leakage anomaly where unrepresented metadata affects operational verdicts, and non-retractive world extensions
Pillar II: Preserves Invariant	State the structural invariant and protected skeleton preserved across transitions.	Invariant: the Effectual-Outside Dichotomy holds so that identical represented support ensures under declared assumptions identical operational outcomes, and every extension proposal carries an explicit retraction down-map Protected Skeleton: ['represented_support', 'observation_views', 'requirement_store', 'retraction_down_map']
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 claim complete knowledge of external reality
• does not grant operational authority to unrepresented variables
• does not allow proposals without base-carrier retractions
• does not imply operational authority

5. Operational Verification & Terminal Routing

5.1 Required Declarations

• world_state
• represented_support_mapping
• extension_proposal
• base_carrier
• extension_carrier
• inclusion_u
• retraction_r
• evaluator_factorization

5.2 Required Evidence

• support_equality_receipt
• evaluator_invariance_receipt
• retraction_identity_proof

5.3 Validation Criteria

Criterion ID	Name	Condition
criterion	Check	two world states with identical represented support yield identical evaluation results
criterion	Check	r(u(b)) = b for every base b; no claim that u(r(e)) = e for every extension e
criterion	Check	inert notes cannot alter requirement satisfaction or quiescence

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
AcceptEndogenousFidelity	Preserve
RejectExternalStateLeakage	Invalidate
RejectInvalidRetraction	Reject
Undetermined	Abstain

5.5 Declared Failure Modes

• symptom: modifying unrepresented notes alters an operational evaluation, diagnosis: operational evaluator violates the No-Outside contract, terminal: RejectExternalStateLeakage
• symptom: proposal down-map mutates an element of the base carrier, diagnosis: the supplied maps fail r composed with u equals id_B, terminal: RejectInvalidRetraction

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.epistemic.efnf (EFNF) against its declared schema, boundary constraints, and witness obligations in this model.
   • Supports deterministic terminal routing (AcceptEndogenousFidelity, RejectExternalStateLeakage, RejectInvalidRetraction, Undetermined) 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 external state leakage anomaly where unrepresented metadata affects operational verdicts, and non-retractive world extensions is either excluded under the Effectual-Outside Dichotomy holds so that identical represented support ensures under declared assumptions identical operational outcomes, and every extension proposal carries an explicit retraction down-map 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.epistemic.efnf.
