GitHub Copilot can now fail closed when managed settings are stale

GitHub's [October 13 update](https://github.blog/changelog/2026‑10‑13‑enterprise‑managed‑settings‑enforcement‑updates/) adds `forceRemoteSettingsRefresh` for supported Copilot clients. When the value is `true`, Copilot must retrieve current managed settings at startup instead of accepting a cached policy response. The control is supported in Copilot CLI, Visual Studio Code and the GitHub Copilot app. It can be delivered through server‑managed settings, mobile‑device management or a file‑based configuration. This closes a specific gap: a recently changed restriction no longer has to wait for the normal settings cache to expire before it reaches a starting client.

With forced refresh active, a cached response cannot satisfy the freshness requirement. GitHub says a client that cannot confirm current policy fails closed instead of starting with stale or unconfirmed settings. The tradeoff is availability. A GitHub outage, blocked network path or broken identity flow can stop Copilot from starting even when yesterday's cached policy was valid. Without the control, clients keep using the normal cache for faster startup and resilience during transient failures. Teams should choose based on the consequence of stale policy. A high‑control environment may prefer a predictable stop; a lower‑risk environment may accept a bounded cache window to preserve developer access.

GitHub distinguishes the delivery channel. MDM‑managed and file‑based settings can require a fresh fetch before a client signs in for the first time. A server‑managed value begins enforcing startup refreshes only after the client has received that value once. That means a server‑only rollout needs a bootstrap check. Administrators should not infer that an uninitialized device failed closed before its first successful policy synchronization. GitHub's [deployment guide](https://docs.github.com/en/enterprise‑cloud@latest/copilot/how‑tos/administer‑copilot/manage‑for‑enterprise/use‑managed‑settings/deploy‑managed‑settings) describes the available managed‑settings channels. Record which channel wins, enroll a clean test device and verify behavior both with the policy service reachable and with it deliberately unavailable.

GitHub is also attaching minimum supported client versions to governance‑focused managed keys, starting with `sandbox`. When that key is present, users pinned to an older Copilot client must update before they can resume using Copilot. The rule prevents an old client from silently ignoring a control it cannot enforce. It can also expose unmanaged version pins, slow desktop deployment rings or compatibility freezes. Before setting the key broadly, inventory client versions and confirm that the approved release is available through every managed channel. Treat an update block as a policy signal, not a reason to remove the sandbox requirement without review.

A complete acceptance test has three layers: the client fetched the current settings, the client enforced each governed feature, and the organization received the expected operational evidence. Those layers should be checked independently. Use a harmless policy delta, capture the resolved managed source, restart the client, and verify the expected allow or deny result. Repeat once with the policy endpoint unavailable to prove the intended fail‑closed or cached behavior. Then restore normal connectivity and confirm recovery. The new control complements GitHub's earlier [fine‑grained Copilot telemetry settings](https://opentools.ai/news/github‑copilot‑telemetry‑identity‑content‑capture‑controls); it does not prove which telemetry fields or sandbox actions occurred.
