Notes on the host, the checkpoint, and the loop after a failure.
Linea Labs is not Consensys Linea
Linea Labs builds Linea, an open-source AI agent runtime at getlinea.app. It is not the Consensys Linea blockchain, and not the Linea Sketch iPad app.

What is an AI agent runtime?
A framework gives you the agent loop. A runtime runs it in production: durable steps, checkpoints, approvals, crash recovery, and replaying one failed step.

Why replay needs the checkpoint
You cannot re-run step four without the exact input it saw. That input only exists if the host executed the run.

Memory is not a side quest
Facts have to survive the run. If you stand up the store yourself, you are still doing the ops half.

Sandbox the code node
A code node is an escape hatch. It still has to run somewhere that cannot take down the host.

Triggers are not the product
Starting a graph is a solved problem. The product is what has to stay up after it starts.
