 - Models/MiniMax: honor `MINIMAX_API_HOST` for implicit bundled MiniMax provider catalogs so China-hosted API-key setups pick `api.minimaxi.com/anthropic` without manual provider config. (#34524) Thanks @caiqinghua.
 - Usage/MiniMax: invert remaining-style `usage_percent` fields when MiniMax reports only remaining percentage data, so usage bars stop showing nearly-full remaining quota as nearly-exhausted usage. (#60254) Thanks @jwchmodx.
 - Usage/MiniMax: prefer the chat-model `model_remains` entry and derive Coding Plan window labels from MiniMax interval timestamps so MiniMax usage snapshots stop picking zero-budget media rows and misreporting 4h windows as `5h`. (#52349) Thanks @IVY-AI-gif.
+- Usage/MiniMax: let usage snapshots treat `minimax-portal` and MiniMax CN aliases as the same MiniMax quota surface, and prefer stored MiniMax OAuth before falling back to Coding Plan keys.
 - MiniMax: advertise image input on bundled `MiniMax-M2.7` and `MiniMax-M2.7-highspeed` model definitions so image-capable flows can route through the M2.7 family correctly. (#54843) Thanks @MerlinMiao88888888.
 - Agents/exec approvals: let `exec-approvals.json` agent security override stricter gateway tool defaults so approved subagents can use `security: "full"` without falling back to allowlist enforcement again. (#60310) Thanks @lml2468.
 - Tasks/maintenance: mark stale cron runs and CLI tasks backed only by long-lived chat sessions as lost again so task cleanup does not keep dead work alive indefinitely. (#60310) Thanks @lml2468.
