Managed-OAuth providers (github_copilot / codex_oauth / xai_oauth) need
proxy takeover to inject credentials, but the "needs routing" badge and
the switch-time warning only keyed off apiFormat — missing OAuth providers
whose upstream format is native (e.g. the new Codex xAI Grok OAuth preset
on openai_responses).
- Add isOAuthProviderType / OAUTH_PROVIDER_TYPES as the SSOT for OAuth types
- Extract providerNeedsRouting() as the authoritative predicate: managed
OAuth always needs routing (the backend rejects these accounts' direct
connection) regardless of apiFormat or Claude Desktop mode
- ProviderCard badges (claude / codex / claude-desktop) and the switch
warning consume the shared predicate instead of raw apiFormat
- Gate the warning on per-app routing readiness: claude-desktop uses
isProxyRunning (backend takeover status has no such field), other apps
use isProxyTakeover — fixes false warnings on Desktop and missing
warnings when the proxy runs but the app isn't taken over
- Force proxy mode for all managed-OAuth providers in the Claude Desktop
form (lock the mode toggle), not only xai_oauth
- Add unit tests for providerNeedsRouting, the switch routing gate, and
Desktop OAuth preset enforcement
- i18n(zh/en/ja/zh-TW): add notifications.proxyReasonManagedOAuth
The default Sonnet tier was bumped to claude-sonnet-5, but the TheRouter preset tests and ClaudeDesktopProviderForm tests still asserted claude-sonnet-4.6/4-6. Update the expected values to match the presets; input fixtures are left as-is to keep exercising legacy-route migration.
Update the Codex chat preset test's Kimi expectation (kimi-k2.6 -> kimi-k2.7-code) after the Kimi K2.7 upgrade, update the Claude Desktop form test for the four-tier (Sonnet/Opus/Fable/Haiku) routes, and reformat UsageDateRangePicker imports (prettier).
- Wire claude-fable-5 as a fourth tier on both proxy paths, with a
fable -> opus -> default fallback mirroring the official downgrade.
- Whitelist the fable- prefix for the Desktop 1.12603.1+ validator.
- Clarify fallbackModelHint (zh/en/ja/zh-TW): a blank tier on
third-party endpoints forwards the literal model name and 404s.
Refs #3980, #4026, #4049.
Claude Desktop's 3P validation only accepts claude-{sonnet,opus,haiku}-*
role IDs, so providers must map every tier. Bring the Desktop mapping flow
in line with Claude Code and fix the fallout that broke sub-agent Haiku calls.
- Proxy form: replace the dynamic route list with fixed Sonnet/Opus/Haiku
tiers; blank tiers backfill from the first filled tier (Sonnet first) on
submit and inherit its supports1m flag
- Backend: add a role-keyword fallback in map_proxy_request_model so dated
official names (e.g. claude-haiku-4-5-20251001) resolve to the right tier,
guarded by is_claude_safe_model_id so [1m]-suffixed IDs stay rejected
- Tighten is_claude_safe_model_id / isClaudeSafeRoute to reject degenerate
role IDs like "claude-sonnet-"
- Fix the seed-effect race where normalizing empty routes to three blank
tiers blocked the default-route backfill
- Sync switch hints, placeholders, and the zh/en/ja/zh-TW locales to the
three-role-ID rule
- Update zh/en/ja user manual (2.1, 2.6), calling out legacy Claude IDs
(claude-3-5-sonnet-...) as a rejected example
Tests: 282 frontend + 34 backend claude_desktop; typecheck, clippy, fmt clean.
Adapt to Claude Desktop 1.6259.1+ fail-all validation which only
accepts claude-(sonnet|opus|haiku)-* route IDs. Branded model names
(DeepSeek, Kimi, GLM, etc.) now live in a new labelOverride field
instead of being embedded in route IDs.
- Backend auto-repairs legacy unsafe routes to the next free
sonnet/opus/haiku slot instead of erroring
- Frontend swaps the free-form route input for a role dropdown plus
menu display name field
- Add CLAUDE_DESKTOP_ROLE_ROUTE_IDS as the single source of truth
for role-to-route mapping; presets and form both consume it
- Drop the dead displayName alias on ClaudeDesktopModelRoute and the
ineffective /v1/models display_name injection (UI ignores it)
- Update i18n (en/ja/zh) and form focus test for the new fields
