Summary

• Add MiniMax as a first-class API-key provider in Settings
• Store minimax-*.json auth files and include them in config hot-reload fingerprints
• Inject a managed OpenAI-compatible MiniMax provider using https://api.minimax.io/v1 with default MiniMax model aliases
• Update provider wiring tests, verification specs, README, and Factory setup docs

MiniMax OpenAI-compatible API reference: https://platform.minimax.io/docs/api-reference/text-openai-api

Testing

• cd src && swift test
• make test
• swiftc Sources/ProviderCatalog.swift Sources/CustomProviders.swift Sources/ConfigComposer.swift Verification/ConfigComposerSpec.swift -o /tmp/ConfigComposerSpec && /tmp/ConfigComposerSpec
• swiftc Sources/ProviderCatalog.swift Sources/CustomProviders.swift Sources/ConfigComposer.swift Sources/ZAIAPIKeyStore.swift Verification/ZAIAPIKeyStoreSpec.swift -o /tmp/ZAIAPIKeyStoreSpec && /tmp/ZAIAPIKeyStoreSpec
• swiftc Sources/ConfigInputFingerprint.swift Verification/ConfigInputFingerprintSpec.swift -o /tmp/ConfigInputFingerprintSpec && /tmp/ConfigInputFingerprintSpec
• git diff --check

Note: swift test still emits the existing AppDelegate.windowDidClose / windowDidExpose warning unrelated to this change.

Reviewed. This is the right shape for a provider addition. Specifically:

• Generalizing ZAIAPIKeyStore into a shared managed-provider store instead of copy-pasting it is the change I would have asked for.
• It routes through the existing ConfigComposer managed-provider path rather than inventing a parallel one, and it respects the enable/disable and fingerprint/hot-reload machinery.
• Tests and verification specs are updated alongside, plus README and FACTORY_SETUP.

Two items before merge:

1. Please confirm https://api.minimax.io/v1 and the eight MiniMax-M* model IDs are current. As with any managed provider, a stale model name just 404s for users.
2. Merge order: feat(menu): add Claude and Codex usage controls #485 moves src/Verification/*Spec.swift into XCTest targets and deletes those files. Your changes touch ConfigComposerSpec, ConfigInputFingerprintSpec, and ZAIAPIKeyStoreSpec, so whichever lands second needs a rebase. My intent is to land this one first so you do not have to redo the work against deleted files.
