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.

Visible incidental differences: status ages, focus/hover, popup shadows, scroll position, and anti-aliasing. Earlier journey recordings contain disposable provider cards and differing sidebar widths; final Settings still pairs have matching three-provider fixtures and 256px sidebars. Base may show Retry sign-in after cancellation while head shows Sign in. No claim that nothing else changed is made.
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 changes production ACP authentication by adding regional MiniMax sign-in behavior and making Global the default method when no method is configured. The authentication path also has an unresolved concern about applying regional arguments to unrelated agents that reuse the same method ID.
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 now advertises Global and Mainland China login methods when no region argument is present. Selecting the Global method starts login with --region global. A fixture script seeds MiniMax Code settings in an isolated home.
Changes: MiniMax Code regional sign-in

Region-aware method discovery and login packages/provider-acp-registry/src/server/minimaxCodeAcp.ts, packages/provider-acp-registry/src/server/auth.ts, packages/provider-acp-registry/src/server/auth.test.ts | The registry adds Global and Mainland China variants when the existing MiniMax Code terminal login has no region argument. Discovery and authentication use the transformed methods. The test checks the Global method and --region global terminal argument. |
Isolated authentication fixture scripts/fixtures/minimax-auth.mjs, knip.jsonc | The script requires an isolated T3 home, rejects paths that alias the live home or settings file, and refuses to seed settings while the isolated server process is running. It writes enabled MiniMax Code settings without credentials. Knip lists the script as an entry. |

Explanation
The description includes all required sections. It explains the problem, change, scope, approval, verification results, evidence, limitations, and agent details. It also provides UI screenshots and recordings as required.
Explanation
Issue #17601 requires a Global sign-in path and an explicit Mainland alternative. withMinimaxCodeRegions advertises Global first with ID minimax-code-login:global and --region global, while it preserves minimax-code-login for Mainland China with --region cn. auth.ts applies the same mapping during discovery and authentication. The test summary verifies method ordering and Global arguments. The API-key path is an alternative issue outcome, not an additional requirement.
Explanation
The production changes are limited to ACP Registry MiniMax authentication discovery and execution. The regression test covers the issue behavior. The fixture hardening and its Knip entry support isolated verification and prevent writes to live settings. No unrelated product behavior or dependency change is shown. The repository diff was unavailable, so this conclusion uses the supplied change summary and inspected file contents.

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.
