2626 The block applies to your wrapper script and lifecycle hooks too, since they share the container. Authenticate any token exchange with the [session JWT](/docs/en/self-hosted-environments-identity) against your own token service over allowlisted egress, or use a file-based web identity such as IAM Roles for Service Accounts (IRSA) on Amazon EKS.
2727* **Per-runner filesystem isolation**: each runner process gets its own working directory that no other process on the host can read or write. Make `--hooks-dir`, the wrapper script, and the host's `~/.claude/` read-only to the session, either built into the image or mounted read-only.
28* **Dispatch is organization-wide**: any member of your Anthropic organization can dispatch a session to any of its environments, and there's no per-environment access control on dispatch. Treat every runner host as reachable for code execution by every org member, and place data or credentials on a runner host only if every org member is allowed to read them. [`--lock-to-account`](/docs/en/self-hosted-environments-reference#runner-cli-flags) bounds which account's sessions a given host executes, but dispatch into the environment itself stays organization-wide. To make self-hosted environments the only picker option, an [Owner or admin](/docs/en/cloud-environments#organization-shared-environments) can hide Anthropic-hosted environments for the whole organization from the [**Cloud environments** page](https://claude.ai/admin-settings/cloud-environments).

2929* **Enforce the repo-settings guard**: choose the guard mode with [`--confine-repo-settings`](/docs/en/self-hosted-environments-reference#runner-cli-flags). The default `warn` logs a violation and still spawns the session, `enforce` refuses the session, and `off` disables the scan. The runner scans each repository's committed settings for:

3131 * A grant that resolves outside that session's own workspace: an `additionalDirectories` entry, an `Edit`, `Write`, or `NotebookEdit` rule in `permissions.allow`, or a `sandbox.filesystem.allowWrite` or `allowRead` entry
