 ### Fixed
+- Claude: distinguish claude-swap account switching from ambient Claude Code sign-in in the menu without changing either action (#2874). Thanks @ynaamane!
 - Codex: avoid full SQLite cost-cache rewrites for unchanged scans while preserving retention, freshness, and concurrent saves (#2852). Thanks @Yuxin-Qiao!
 - Azure OpenAI: allow enough v1 completion budget for reasoning-capable deployment validation while keeping the probe bounded (#2867). Thanks @yilinxia!
 - Codex: preserve request-level pricing tiers while reconciling forked usage, preventing day aggregates from triggering long-context rates (#2858). Thanks @thomaschow19!
