Incremental tools and coordinated MCP OAuth refresh now default on. Responses Lite tool catalog updates enter request history by default, and MCP OAuth refresh coordination also becomes stable/default-on. These are two distinct default changes, not activation of ranked Code Mode discovery or live MCP catalog refresh.
Channel: tagged-release. Half: capability. Date: 2026-10-23.
Operator consequence: Test request-history compatibility as catalogs change and refresh credentials through multiple clients. Compare native coordination with token-refresh wrappers before deleting the latter; no latency or refresh-rate benchmark was run.
