{"service": "instem dev \u2014 remote correctness brain + workflow provisioner", "version": "1", "what_it_is": "instem is a DETERMINISTIC, caged task-runner backed by a remote correctness brain. You describe work as TASKS (each with acceptance criteria + the files it may touch); the runner dispatches each task to a sandboxed `claude` worker on YOUR subscription that can write ONLY inside the task's scope (the cage). The worker's output is GRADED against the task's acceptance criteria and scope-checked by this brain before it is applied, VERSIONED, and shipped \u2014 100% accuracy is the entry condition; anything less does not ship. This URL is the BRAIN: it hosts the proprietary judgment and PROVISIONS the runner into your project on demand (POST /v1/bootstrap). Your code is judged in memory and never stored; the worker runs on your subscription, so the framework costs no API tokens.
