Interfaces

PreFlight — Deterministic Upstream Data Ingestion Gate

Interaction Surface

PreFlight exposes a narrow deterministic enforcement interface.

• Inputs are submitted explicitly
• Evaluation executes mechanically
• Outputs return fixed enforcement results

No interactive session model exists.

PRE-FLIGHT INTERACTION MODEL — v1.01

Interface Type:
Deterministic enforcement interface.

        ├── PASS  → Downstream execution permitted

Machine-Readable Enforcement Artifact

Interface Properties:
• Non-interactive execution
• No runtime negotiation
• Fixed execution order
• Upstream-only integration

Input Interface

PreFlight accepts structured tabular datasets with explicit parsing context.

• Dataset payload
• Declared parsing parameters
• Deterministic execution configuration

Inputs are evaluated exactly as delivered.

No inference layer exists at the interface boundary.

Execution Interface

Execution is externally initiated.

PreFlight does not orchestrate ingestion.

• Invocation triggers deterministic evaluation only
• Execution order remains fixed

No adaptive runtime negotiation occurs.

Output Interface

PreFlight returns machine-readable enforcement artifacts.

• Deterministic verdict
• Structured validation results
• Failure evidence when verdict is BLOCK

Outputs reflect enforcement outcomes only.

Integration Boundary

Interfaces remain upstream of downstream systems.

• No execution occurs inside warehouses, pipelines, or model runtimes

Integration occurs through explicit invocation only.

Configuration Surface

Configuration declares structural parameters and enforcement scope.

• Rule definitions
• Parsing parameters
• Execution parameters

Configuration defines structural boundaries.

It does not introduce adaptive behavior.

Isolation Principle

Interfaces expose enforcement outcomes only.

• No runtime inspection channel
• No interactive debugging surface
• No mutable control layer

Interaction remains one-directional: input → evaluation → verdict.

Operational Posture

• Upstream
• Deterministic
• Mechanical
• Auditable
• Non-interactive
