Audit Trail & Event Log

Real-time JDBC persistence layer logging all device lifecycle events and state changes.

Architectural Deep Dive

Highly technical modules engineered for deterministic orchestration and observability.

Custom IoC & Dependency Management

Reflection-based classpath scanning and metadata-driven wiring (e.g., @Timed, @DataSensitive). The AppContainer performs runtime "Proxy Swap" to manage lifecycles and cross-cutting concerns.

Dynamic Proxy Interception (AOP)

JDK Dynamic Proxies with a PerformanceHandler InvocationHandler provide zero-touch instrumentation, latency monitoring and threshold enforcement at the proxy layer.

Command-Pattern Orchestration

Encapsulated Command objects, audit-ready actions, and Deque-based priority dispatch (e.g., PanicCommand) enable sub-millisecond response and deterministic retry semantics.

JDBC Persistence & Audit Logging

Lightweight SQLite-backed JDBC repository for durable event persistence, efficient state recovery, and tamper-evident audit trails without heavy ORM overhead.
