PreFlight — Deterministic Upstream Data Ingestion Gate

pf_v1.01 is a deterministic data admission gate: an appliance, not a framework.

Definition

PreFlight is a deterministic upstream ingestion enforcement engine.

It operates between dataset acquisition and downstream processing.

  • Evaluates datasets prior to ingestion
  • Issues a single deterministic verdict
  • Operates outside downstream systems
  • Performs no data mutation

Operational Position

  • Positioned immediately after dataset acquisition
  • Evaluates before storage, analytics, or model intake
  • Establishes a deterministic verdict boundary
  • Downstream execution follows verdict issuance

Acquisition → PreFlight → Downstream Execution

Operational Role

Produces enforcement outcomes only. Performs no remediation. Ingestion decisions remain external.

Datasets deleted after evaluation. Data Handling.

Problem Class

  • Certain ingestion defects do not surface during load
  • Data imports successfully
  • Systems operate normally
  • Outputs appear structurally plausible
  • Latent structural faults persist

PreFlight exists to expose ingestion risk prior to downstream execution.

Scope boundaries: Compliance.

Identity Constraint

PreFlight answers one question:

Is this dataset mechanically safe to ingest as-is without risking silent downstream structural damage?
