Core domain and application logic for Identa

Identa Core 🧠

The engine room of Identa. This package contains the pure domain logic, ports, and application handlers following a strict Hexagonal Architecture and CQRS pattern.

Architecture

Identa Core is designed to be framework-agnostic and side-effect free. It enforces a clean separation between "how we evaluate" and "how we store/trace".

Hexagonal Layers

1. Domain: Pure Pydantic models (Runs, Spans, AgentStructure) and core logic (Metric computation, Migration validation).
2. Ports: Abstract interfaces for storage and artifacts.
3. Application:
   • Commands: Mutation logic (Start Run, Log Results).
   • Queries: Data retrieval logic (List Runs, Get Comparison).
4. Persistence (Adapters): Concrete implementations of ports (SQLite, Local Filesystem).

Key Components

• Evaluation Engine: The loop that executes agents against test suites and computes metrics.
• Tracing Service: A context-aware span collector.
• Migration Engine: Logic to validate and apply model-binding swaps.
• Reproduction Engine: Logic to replay experiments with structural drift detection.
