Guarantees

PreFlight — Deterministic Upstream Data Ingestion Gate

PreFlight v1.01 guarantees deterministic upstream ingestion enforcement behavior within its defined scope.

Execution Guarantees

• Fixed execution order
• Deterministic verdict reduction
• Mechanical analysis only
• No probabilistic behavior
• No adaptive or model-based logic
• No mutation of input datasets
• Identical inputs produce identical outcomes

Boundary Guarantees

• Operates strictly upstream of downstream systems
• Performs no downstream system interaction
• Executes no workflow logic inside external platforms
• Performs no semantic interpretation
• Enforces no business rules
• Performs no data quality scoring
• Performs no remediation or correction

Verdict Contract

Each evaluation produces exactly one deterministic outcome:

• PASS — Downstream execution permitted
• WARN — Downstream execution permitted with exposure
• BLOCK — Downstream execution not recommended
• ANALYSIS_INCOMPLETE — Admission not proven

Reduction is mechanical. No scoring, weighting, or interpretive logic exists.

Insufficient Evidence Guarantee

• If ingestion safety cannot be mechanically established, the system does not issue a PASS outcome
• The evaluation remains within deterministic execution rules
• Output is limited to structured verdict and report
• No speculative conclusions are produced

Auditability Guarantee

• Execution path is reproducible
• Evidence is reproducible
• Verdict is reproducible
