Sprint 4 Engineering Log

Program Context

• Phase: Phase 3
• Sprint: Sprint 4
• Status: Completed
• Primary Architecture Layers: VectorVue Integration Layer, Telemetry Ingestion

Architectural Intent

Design and implement the secure integration client model for external telemetry/export pathways via VectorVue.

Implementation Detail

VectorVue client contracts were implemented with TLS transport, retry/backoff policy, event batching semantics, and message integrity controls.

Security and Control Posture

• AAA scope and authorization boundaries are enforced according to current orchestrator policy.
• Telemetry and audit events are expected to remain structured, attributable, and export-ready.
• Integration interfaces are maintained as loosely coupled contracts to preserve VectorVue interoperability.

QA and Validation Evidence

Integration QA scaffolding and client-level error modeling were introduced to support enterprise transport assurance.

Risk Register

Primary risk was unreliable external API behavior; mitigated through retries, batching controls, and explicit exceptions.

Forward Linkage

Sprint 5 performed API QA and encrypted transport verification.
