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.relativistic.time_sync
Pillar I: Excludes Anomaly	Name and eliminate a specific class of data or state defects.	assuming global time is exact, treating overlapping uncertainty intervals as physical simultaneity, silent clock epoch resets, and conflating missing timing evidence with computational exhaustion
Pillar II: Preserves Invariant	State the structural invariant and protected skeleton preserved across transitions.	Invariant: timestamps explicitly bound uncertainty intervals [t_nominal - offset, t_nominal + offset] based on declared reference epoch, drift bounds, and epoch reset history, routing unresolved overlaps to epistemic abstention Protected Skeleton: ['clock_id', 'reference_epoch_id', 'elapsed_time_basis', 'drift_rate_bound', 'offset_uncertainty_interval', 'epoch_reset_identifier', 'relation_type']
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)

• overlapping uncertainty intervals represent lack of resolved timestamp order, not proof of physical simultaneity or network concurrency
• does not convert bounded clock intervals into absolute Newtonian simultaneity
• does not authorize total ordering without disjoint certified intervals or an explicit consensus serialization certificate
• missing timing evidence or unresolved intervals do not denote computational budget exhaustion

5. Operational Verification & Terminal Routing

5.1 Required Declarations

• clock_id: unique local oscillator identifier
• reference_epoch_id: declared synchronization epoch
• elapsed_time_basis: monotonic elapsed counter since epoch
• drift_bound: maximum drift rate rho (e.g. microseconds per second)
• offset_bound: maximum synchronization offset epsilon at last sync
• epoch_reset_log: history of clock adjustments and epoch step changes
• relation_type: enum [timestamp_interval_order, consensus_logical_serialization]

5.2 Required Evidence

• clock_sync_trace: list
• drift_measurement_records: list
• offset_interval_bounds: dict
• reset_event_log: list
• consensus_certificate_if_total_order_claimed: string_or_null

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
TimeCertified	Preserve
UnresolvedIntervalOverlap	Abstain
DriftBoundExceeded	Invalidate
EpochResetRequired	Repair
ConsensusSerialized	Serialize
Unsupported	Unsupported

5.5 Declared Failure Modes

• symptom: wall-clock timestamps from two unsynchronized nodes are compared as exact scalars, diagnosis: absolute time assumption; overlapping uncertainty intervals, terminal: UnresolvedIntervalOverlap
• symptom: clock drift exceeds declared maximum rate bound, diagnosis: synchronization failure, terminal: DriftBoundExceeded

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.relativistic.time_sync (CSNF) against its declared schema, boundary constraints, and witness obligations in this model.
   • Supports deterministic terminal routing (TimeCertified, UnresolvedIntervalOverlap, DriftBoundExceeded, EpochResetRequired) 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 assuming global time is exact, treating overlapping uncertainty intervals as physical simultaneity, silent clock epoch resets, and conflating missing timing evidence with computational exhaustion is either excluded under timestamps explicitly bound uncertainty intervals [t_nominal - offset, t_nominal + offset] based on declared reference epoch, drift bounds, and epoch reset history, routing unresolved overlaps to epistemic abstention 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.relativistic.time_sync.
