    Our Premise

    The frontier is the infrastructure around the model, not the model itself.

    Foundation models are widely available. The differentiation comes from the layers built around them: memory that persists across sessions, governance that keeps behavior coherent over time, coordination that handles the parallelism that complex tasks require.

    Meridian is our answer to what that infrastructure looks like in practice. These are the three principles it's built on.

    Memory over context

    A context window is retrieval. Memory is accumulation. AI systems that accumulate structured experience over time behave differently from systems that reset with every session. The architecture that enables this is where most of the implementation work lives.

    Governed evolution

    Systems that run continuously evolve whether you govern that evolution or not. Governance works as an infrastructure layer, proposal, review, version, audit, rather than a correction applied after drift becomes visible. Systems built with this structure tend to stay coherent at scale.

    Distributed intelligence

    Capability in complex tasks comes from coordinated agents, not from a single model working sequentially. The task graph, how work decomposes, routes, executes in parallel, and reconciles, is the structural unit of a multi-agent system. Coordination infrastructure is where most of the open engineering problems are.

    What Meridian Does

    Four capability layers. Each independently useful. Together, the infrastructure for autonomous AI systems that actually work at scale.

    In Production

    Meridian runs continuously across a multi-node environment. These are measurements from the live system.

    End-to-end dispatch verified

    A task submitted through the dispatch layer reaches completion, including agent execution, write-back, and status transition, in under 22 seconds. Verified against a live taskboard with full activity log.

    Persistent agent identity

    Agents in Meridian carry versioned configuration, behavioral memory that accumulates across sessions, and an explicit growth framework: proposals, review, approval. Task agents are spawned on demand and closed on completion. Governed agents persist and evolve.

    MCP integrations

    Live ecosystem integration

    Five MCP integrations expose real-time ecosystem state to agents: taskboard, doc-source, dev-launcher, agent-core, and dep-scanner. Agents operate with current structured context drawn from 20 live services, not static prompts.

    governance cycles

    Growth proposal system live

    Agent governance cycles, session review, goal discovery, self-model synthesis, and growth proposal generation, run in production. Proposals accumulate in a review queue; approved changes version the agent configuration.
