Claude Code 2.1.278: auto-mode safety checks go server-side, unbilled
Claude Code 2.1.278 defaults auto mode’s safety classifier to the server for Claude API/Enterprise and Bedrock/Vertex/Foundry/gateways, so those checks ride with session requests and aren’t billed separately. Gateways that strip safeguards fields fall back to the old billed path; /status shows an Auto mode server row.
