Visual Transition Summary

Stage	Carrier / Operator	Concrete State / Invariant
1. Before / Candidate Input	Input Carrier (ENF Candidate)	Anomaly risk: omniscience fiction
2. Normalization / Gate	ENF Verification Gate	every outward claim... (certified_implies_authorized: false)
3. After / Certified Output	Certified ENF Output	Invariant: ['what_is_known', ; 'by_whom', 'as_of_when', ; 'under_authority', 'uncertainty...

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.enf
Pillar I: Excludes Anomaly	Name and eliminate a specific class of data or state defects.	omniscience fiction
Pillar II: Preserves Invariant	State the structural invariant and protected skeleton preserved across transitions.	Invariant: every outward claim decomposes into known by_whom as_of_when authority uncertainty challenge_terminal Protected Skeleton: ['what_is_known', 'by_whom', 'as_of_when', 'under_authority', 'uncertainty', 'terminal_if_challenged']
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)

• master packet; defers operational checks to LNF RNF StNF FNF ANF BQNF CODA-MUR until composed

5. Operational Verification & Terminal Routing

5.1 Required Declarations

• what_is_known
• by_whom
• as_of_when
• under_which_authority
• with_what_uncertainty
• terminal_route_if_challenged

5.2 Required Evidence

• subordinate NF packets or refs

5.3 Validation Criteria

Criterion ID	Name	Condition
criterion	Check	no field omitted on outward claims
criterion	Check	challenge routes reuse BQNF CODA-MUR terminals
criterion	Check	composition of subordinate contracts verified

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
ClaimOk	Escalate
Escalate	Escalate
Invalidate	Invalidate
Refuse	Refuse
Recompute	Recompute

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.epistemic.enf (ENF) against its declared schema, boundary constraints, and witness obligations in this model.
   • Supports deterministic terminal routing (ClaimOk, Escalate, Invalidate, Refuse) 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 in_motion, this contract enforces that omniscience fiction is either excluded under every outward claim decomposes into known by_whom as_of_when authority uncertainty challenge_terminal 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.enf.
