CLAUDE_CODE_SESSION_ORIGIN is now read and added to the allow-listed/passthrough environment variable sets used when spawning subsessions. In the same change, GIT_ALLOW_PROTOCOL was added to the git-environment-variable passthrough allowlist, and CCR_SESSION_PROFILE was added to separate internal environment-variable lists (one for eval/runner context, one for a startup-context safelist).
