LegionIO chains tasks into dependency graphs across a RabbitMQ fleet, or fully in-process via lite mode with zero infrastructure. Optional layers install as independent gems: legion-llm adds tiered LLM routing with mid-stream failover and context curation, legion-mcp adds an MCP server, legion-rbac adds access control. All open source, no feature gates.

A proxy between AI clients and model backends. Requests translate once to a canonical form, route to the cheapest capable tier (local, direct, fleet, cloud, frontier), and escalate on failure with circuit breakers and mid-stream failover. A post-turn Curator bounds long agent sessions (97.7% context reduction vs naive resend at 50+ turns, production-measured). Provider adapters are separate lex-llm-* gems.
