# Tollana

> A runtime for long-running AI agents that can pause, move, and pick up exactly where they left off. Durable runs, a complete audit trail, and a host you can swap without rewriting the agent.

Agents that pause, move, and pick up exactly where they left off.

A run is something you can suspend, restore, replay, and meter. Guests start with nothing. Every power is a grant.

## journal

- **Durable:** Stop mid-work, restore on another machine, continue without loss. Snapshots are exact, not a best-effort dump.
- **Portable:** The same guest runs from a phone or embedded device through a laptop to a cluster or the edge. The host changes; the agent does not.
- **Modular:** Models, files, networks, and other powers are not baked into the core. The host attaches only what that run may use.
- **Swappable:** Change providers, local vs cloud models, storage, or policy without rewriting the agent. A restore will not silently bind a different plugin version.
- **Auditable:** Meaningful steps are journaled as they happen. Replay and inspect instead of reconstructing leftover logs.
- **Least privilege:** Guests start with nothing. Every power is an explicit, attenuable capability. Sensitive data can stay on-device by policy.
- **Accountable:** Budgets for compute and tokens are first-class. Cost is attributable per run and per sub-goal.
- **Untrusted by default:** Model-generated code runs in isolation, on a tight budget, with only the capabilities you pass in.

## machine

- **host:** Resolves plugins, grants capabilities, and holds policy. Replace the host without rewriting the guest.
- **core:** An explicit interpreter. It suspends, resumes, meters, journals, snapshots, and enforces grants. It does not know about models or files.
- **guest:** The agent program. It only sees what the host placed in its hands.

Apache-2.0. The architecture RFC and the runtime live in the same repository.

In Stargate, the Tollan rebuilt on Tollana after sharing technology destroyed a neighboring world. They did not share it that way again.
