Sprint 9.5 Engineering Log

Program Context

• Phase: Phase 3
• Sprint: Sprint 9.5
• Status: Completed
• Primary Architecture Layers: Telemetry Ingestion, Orchestration Pipeline

Architectural Intent

Standardize asynchronous telemetry delivery via broker abstraction with reliability semantics suitable for production operations.

Implementation Detail

RabbitMQ-first TelemetryPublisher abstraction, async delivery path, bounded retries, DLQ routing, idempotency key handling, and dockerized runtime wiring were implemented.

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

Unit and integration suites validated publish/consume behavior, queue semantics, and remote endpoint configuration handling.

Risk Register

Primary risk was message duplication and delivery inconsistency; mitigated with idempotency and dead-letter design.

Forward Linkage

Sprint 9.6 advanced operator interfaces (web UI + admin TUI).
