Exposes RobotLab robots and networks as A2A agents over HTTP+SSE. Implements the Agent2Agent Protocol v1.0 (Linux Foundation) via the simple_a2a gem. Supports sync and interactive execution modes, bridging RobotLab's AskUser tool to A2A's input_required/resume lifecycle for multi-turn flows without a terminal dependency.

Provides RobotLab::DocumentStore — a thread-safe, in-memory semantic search store backed by fastembed (BAAI/bge-small-en-v1.5). Store text documents by key and retrieve the closest matches to a natural-language query using cosine similarity. Works standalone or as a drop-in extension for robot_lab agents and networks.

Provides RobotLab::Durable — a YAML-backed knowledge store that lets robot_lab agents accumulate and recall observations across sessions. Includes Entry (immutable value object with confidence scoring), Store (file-locked per-domain persistence), Reflector (end-of-session promoter), and the Learning mixin with RecallKnowledge/RecordKnowledge tools that integrate directly into Robot when robot_lab is present.

Provides RobotLab::RactorWorkerPool — a pool of Ruby Ractor workers for executing CPU-bound, Ractor-safe tools in parallel. Includes RactorBoundary (deep-freeze utility for crossing Ractor boundaries), RactorJob/RactorJobError/RobotSpec (frozen data carriers), RactorMemoryProxy (shared Memory access from inside Ractors), and RactorNetworkScheduler (dependency-ordered pipeline across Ractors).

Provides Rails Engine, Railtie, ActiveJob base class with Turbo Stream support, persistence models, and generators for using robot_lab in Rails applications.
