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?
