Adding MiniMax Code and choosing Sign in always started the CLI's default regional login, which opens agent.minimaxi.com for a fresh account. Global accounts had no sign-in choice in the existing provider flow.
Expose Global and Mainland China variants of MiniMax Code's advertised terminal login method. Global is first; each choice passes the CLI's explicit region flag. The original method ID remains available for existing settings, and upstream region-aware methods pass through unchanged.

Unverified: native mobile, macOS Electron external-browser handoff, and successful account login. The Mainland endpoint was observed at 390px; its external form eventually rendered with missing-glyph labels, so form readability remains unverified. Responsive web captures are not native-mobile proof. Local direct connection was exercised; transport code is unchanged.

Verdict: Needs Human Approval
Macroscope's review found this PR requires human approval — This adds Global and Mainland China sign-in choices for MiniMax Code, with Global becoming the fallback selection. Human review must confirm that default-region change and the existing login ID’s new explicit Mainland China behavior.
You can add or adjust custom eligibility rules. Learn more.
Confirmed: Global is the fallback when no sign-in method is selected or configured; the existing method ID explicitly selects Mainland China. This fixes the reproduced regional sign-in bug. The human-review routing remains applicable.

MiniMax Code authentication discovery now exposes Global and Mainland China login options when its terminal login has no region argument. Authentication lookup uses those transformed methods, and selecting Global starts terminal login with --region global.

Explanation
The description includes Problem, Change, Scope and approval, and Verification sections. It explains the regional sign-in behavior, links the related issue, documents focused tests and manual verification, and identifies remaining unverified areas.
Explanation
Issue #17601 requires a Global sign-in path and an explicit Mainland China alternative. withMinimaxCodeRegions transforms the MiniMax Code terminal method into Global first with --region global, while it keeps minimax-code-login for Mainland China with --region cn. auth.ts applies this mapping during discovery and authentication, so the selected method receives the correct arguments. The regression test verifies method ordering, ID preservation, and Global terminal arguments. The API-key path is an alternative issue resolution, not an additional requirement.
Explanation
The production changes are limited to MiniMax Code authentication method transformation and its use during ACP Registry discovery and authentication. The added test directly covers the linked issue. The reported fixture hardening supports isolated verification and does not change production behavior. No unrelated product behavior or dependency change is shown.

CodeRabbit findings: the fixture guard now canonicalizes both paths before creating directories in a85d44a876. A fresh audit reproduced the old settings overwrite and verified that symlinked live homes, aliases, and a missing live home are refused without modifying a JSON sentinel. Normal isolated seeding remains idempotent. The method-ID match is intentional: minimax-code-login is the MiniMax-specific terminal method, and matching it also supports locally installed MiniMax under a different registry entry. No supported non-MiniMax collision was identified; adding a registry-ID restriction would exclude that existing path.

Fixed the settings-destination alias finding in dd61206eca. The fixture compares canonical settings destinations before creating directories or reading files. Temporary-home reproductions showed both userdata-directory and settings-file symlinks overwriting the sentinel before the fix; both now refuse and preserve it. The original live-base guard, normal idempotent seeding, and preservation of unrelated settings also pass. No production code changed.

looks good, looking forward to have this one merged. thank you @juliusmarminge
Confirming this on Linux (T3 Code desktop AppImage, MiniMax Code 0.2.7 from the ACP registry) and testing the approach in this PR against the CLI directly.
Repro: Settings → Providers → MiniMax Code → Sign in runs mcode acp login with no region. I ran the login with HOME set to an empty temp dir and a stub xdg-open that only logs the URL, so no account was touched and nothing was completed:
| Command | URL it tries to open |
|---|---|
mcode acp login | https://agent.minimaxi.com/login?... (Mainland China) |
mcode acp login --region global | https://agent.minimax.io/login?... |
mcode acp login --region cn | https://agent.minimaxi.com/login?... |
So the single advertised terminal method (minimax-code-login, args ["login"]) is what lands on the Mainland host, and passing --region global is enough to fix it, which is what withMinimaxCodeRegions does.
One extra data point: a newer CLI (0.7.4, which I have installed separately) still advertises only minimax-code-login / ["login"] over ACP initialize, and its default login is also Mainland (account.minimax.cn). So the method expansion should stay useful after the registry moves past 0.2.7.
Read the diff only; I haven't built this branch. I'll leave a +1 here rather than open a duplicate PR.
