Assurance

PreFlight — Deterministic Upstream Data Ingestion Gate

Assurance Scope

Assurance verifies deterministic enforcement behavior of the PreFlight v1.01 engine.

Verification applies exclusively to:

• Execution determinism
• Mechanical verdict reduction integrity
• Static structural integrity
• Security execution surface analysis
• Runtime dependency exposure review

Scope is limited strictly to enforcement engine behavior.

Hosted infrastructure, deployment environments, operational configuration, and external integrations are outside the v1.01 assurance boundary.

Deterministic Enforcement Integrity

• Execution order is immutable
• Verdict reduction is mechanical
• Identical inputs yield identical outcomes
• No probabilistic constructs exist
• No adaptive logic exists

Validation confirms deterministic upstream ingestion enforcement behavior.

PRE-FLIGHT ASSURANCE SUMMARY — v1.01

Scope:
Enforcement engine behavior only
Hosted infrastructure excluded

Verification Domains:
- Deterministic execution integrity
- Mechanical verdict reduction
- Static structural analysis
- Security execution pattern review
- Dependency audit

Validation Model:
Deterministic integration-based behavioral verification
aligned with ingestion enforcement architecture.
  

Validation Model

• Structural traversal verified
• Reduction logic exercised end-to-end
• Deterministic state transitions confirmed
• Reproducibility validated under identical input conditions

The validation model reflects enforcement architecture rather than modular feature isolation.

PRE-FLIGHT VETTING SUMMARY — TEST VALIDATION

Tooling: pytest
Model: Deterministic integration validation

Scope:
Full enforcement engine execution path

Verification:
- Fixed execution order confirmed
- Deterministic state transitions verified
- Mechanical reduction logic exercised end-to-end
- Identical input reproducibility validated

Conclusion:
Enforcement behavior aligns with deterministic ingestion design.
  

Validation Coverage Model

Coverage metrics are not used as a proxy for deterministic enforcement integrity in v1.01.

Validation focuses on full-path deterministic execution and reduction stability within defined scope.

PRE-FLIGHT VETTING SUMMARY — VALIDATION MODEL

Tooling: coverage.py
Model: Behavioral execution verification

Objective:
Confirm deterministic enforcement behavior across full execution path

Posture:
Validation prioritizes mechanical determinism and reduction stability
over branch enumeration metrics

Conclusion:
Deterministic execution integrity verified under integration model.
  

Static Structure Verification

• No structural violations identified
• No stochastic constructs present
• No dynamic evaluation mechanisms present
• Codebase constrained to bounded deterministic evaluation

Structural integrity aligns with enforcement-only design.

PRE-FLIGHT VETTING SUMMARY — STATIC ANALYSIS

Tool: Ruff
Scope: v1.01 enforcement codebase

Result:
No structural violations detected

Conclusion:
Codebase integrity consistent with bounded deterministic execution.
  

Security Surface Verification

• No dynamic code execution
• No interactive runtime surface
• No unsafe execution constructs identified by static analysis
• No injection primitives detected within enforcement scope

Security verification applies to enforcement engine behavior only.

PRE-FLIGHT VETTING SUMMARY — SECURITY ANALYSIS

Tool: Bandit
Scope: v1.01 enforcement codebase

Result:
No unsafe execution constructs identified

Conclusion:
Execution surface verified as mechanically bounded.
  

Dependency Exposure Review

• Advisories identified with remediation paths
• No dynamic network interaction within v1.01 engine boundary
• Exposure limited to execution environment context

Dependency management required prior to hosted deployment boundary.

PRE-FLIGHT VETTING SUMMARY — DEPENDENCY AUDIT

Tool: pip-audit
Scope: Runtime dependencies

Result:
Advisories identified with defined remediation paths

Exposure Context:
- Engine operates within bounded execution surface
- No dynamic network interaction in v1.01 scope

Conclusion:
Dependency exposure managed within defined enforcement boundary.
  

Assurance Boundary

Assurance confirms deterministic ingestion enforcement integrity only.

Not evaluated:

• Business correctness
• Semantic validity
• Workflow orchestration
• Hosted infrastructure
• Deployment hardening
• Operational governance

Assurance reflects mechanical enforcement integrity within defined scope.
