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.

Appends structured records for network runs, robot invocations, and tool calls to a SQLite database for post-mortem analysis.

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 — an adapter between robot_lab and the HTM gem (Hierarchical Temporal Memory). Replaces the former YAML store with PostgreSQL-backed long-term memory featuring vector embeddings, hybrid semantic search, hierarchical tagging, and multi-robot federation. Includes RecallKnowledge and 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.

robot_lab-to ("takeover") runs a robot_lab Robot in an autonomous loop, committing one focused change per iteration toward a stated objective. Each iteration the robot reads shared notes (notes.md), does work, then calls submit_iteration_result to report success or failure. The orchestrator commits good iterations, rolls back failures, and appends to the notes log for cross-iteration memory. Stop conditions include max iterations, max tokens, consecutive failure threshold, and a natural- language --stop-when condition. Runs overnight; review the branch in the morning.

A Rails-free Sinatra + HTMX + SSE web interface for robot_lab. Register robots, chat with them from the browser, and watch each lifecycle event (tool calls, results, errors) stream in real time via robot_lab's hook system.
