Qualification	Extended Form Contract (Normal Form Contract)
Data / Math Posture	in_motion
Index Status	draft

Foundational Treatise Specification

• Levels: Level 12
• Spec Files: ['12_grammar.md', '12_math.md']
• Anomaly Excluded: State desynchronization, unverified side effects, and non-reproducible trace execution.
• Preserved Invariant: Every event record structured as immutable 13-tuple projecting to 4-field irredundant kernel.
• Lossless Reconstruction: Deterministic step-by-step replay reconstructs identical state hashes and defect vectors.

Visual Transition Summary

Stage	Carrier / Operator	Concrete State / Invariant
1. Before / Candidate Input	Input Carrier (DDANF Candidate)	Anomaly risk: a trace that cannot ; be replayed to the same state ; hashes and the same defect vectors
2. Normalization / Gate	DDANF Verification Gate	every event is the declar... (certified_implies_authorized: false)
3. After / Certified Output	Certified DDANF Output	Invariant: ['thirteen_tuple', ; 'four_field_kernel']

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.evidence.ddanf
Pillar I: Excludes Anomaly	Name and eliminate a specific class of data or state defects.	a trace that cannot be replayed to the same state hashes and the same defect vectors
Pillar II: Preserves Invariant	State the structural invariant and protected skeleton preserved across transitions.	Invariant: every event is the declared 13-tuple, and its projection to the four-field kernel is a function of that tuple Protected Skeleton: ['thirteen_tuple', 'four_field_kernel']
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 define the internal meaning of the thirteen components beyond the positions given in the source
• does not treat a matching final hash as a substitute for step-by-step replay
• does not imply authorization

5. Operational Verification & Terminal Routing

5.1 Required Declarations

• event_tuple_arity: 13
• kernel_projection: ['B', 'C', 'x', 'Omega']

5.2 Required Evidence

None declared.

5.3 Validation Criteria

Criterion ID	Name	Condition
criterion	Check	each event has the thirteen components in the declared order
criterion	Check	the kernel equals the declared projection of that event
criterion	Check	replay of the ledger reproduces the stored hashes and defect vectors

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
Accept	Preserve
RejectMalformedTuple	Reject
RejectReplayMismatch	Reject

5.5 Declared Failure Modes

• symptom: an event arrives with a component missing or reordered, diagnosis: the record is not the declared 13-tuple, terminal: RejectMalformedTuple
• symptom: replay yields a different state hash, diagnosis: the ledger does not determine the recorded state, terminal: RejectReplayMismatch

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.evidence.ddanf (DDANF) against its declared schema, boundary constraints, and witness obligations in this model.
   • Supports deterministic terminal routing (Accept, RejectMalformedTuple, RejectReplayMismatch) 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 a trace that cannot be replayed to the same state hashes and the same defect vectors is either excluded under every event is the declared 13-tuple, and its projection to the four-field kernel is a function of that tuple 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.evidence.ddanf.
