+- **2026-03-17**: Deprecated user-facing GLMT discovery across CLI help, completions, presets, and docs. Existing `glmt` profiles now run through a compatibility path that normalizes legacy proxy settings to the direct GLM endpoint.
 - **#744**: API profile creation now keeps featured providers in a horizontal rail with scroll fallback, moves Anthropic Direct API to the end, reuses the shared Claude logo, and separates the custom-endpoint entry point from advanced template discovery.
 - **#724**: Codex startup is now free-plan safe. CCS defaults new Codex sessions to a cross-plan model and auto-repairs stale paid-only Codex defaults when the active account is on the free plan.
 - **#737**: Dashboard model pickers in Cursor, Copilot, and CLIProxy now use a searchable combobox with autofocus and explicit no-results states for large model catalogs.

-## GLMT Proxy Flow
+## Legacy GLMT Compatibility Flow
 
 ### Overview
 
-GLMT proxy enables seamless integration with GLM-compatible APIs (Z.AI, Kimi, OpenRouter, etc.) using a Node.js-based embedded proxy.
+GLMT is no longer a marketed runtime surface in CCS. Existing `glmt` profiles are kept as a compatibility path and normalized at launch to the direct GLM endpoint. The `src/glmt/` module remains because Cursor response translation still imports its transformer pipeline.
 
 ```

-### Supported GLM Providers
+### Supported Migration Targets
 
 | Provider | Config Key | Endpoint | Auth |
 |----------|------------|----------|------|
-| Z.AI (GLM) | `glmt` | https://open.bigmodel.cn/api/paas/v4/ | API key |
-| Kimi | `kimi` | https://api.moonshot.cn/v1/ | API key |
-| OpenRouter | `openrouter` | https://openrouter.ai/api/v1/ | API key |
+| Z.AI (GLM) | `glm` | https://api.z.ai/api/anthropic | API key |
+| Kimi API | `km` | https://api.kimi.com/coding/ | API key |
+| Legacy compatibility | `glmt` | normalized to direct GLM at runtime | existing profile only |
 
-Note for `config/base-kimi.settings.json`: the default base URL is `http://127.0.0.1:8317/api/provider/kimi` (local CLIProxy route). For direct Moonshot API access, override `ANTHROPIC_BASE_URL` to `https://api.moonshot.cn/v1/`.
+Use `ccs glm` for Z.AI profiles and `ccs km` for reasoning-first Kimi API profiles. Keep `glmt` only when migrating an existing settings file.
 
-### GLMT Profile Detection
+### Runtime Handling
 
-CCS detects GLMT profiles and routes through `execClaudeWithProxy()`:
+CCS detects the deprecated `glmt` profile name and normalizes legacy proxy-only settings before dispatching through the normal settings-profile flow:
 
 ```typescript
-// Settings-based profile detection
-const settings = loadSettings(profileName);
-if (settings.env?.ANTHROPIC_BASE_URL?.includes('glm') ||
-    settings.env?.ANTHROPIC_BASE_URL?.includes('moonshot') ||
-    settings.env?.ANTHROPIC_BASE_URL?.includes('openrouter')) {
-  return execClaudeWithProxy(claudeCli, profileName, args);
+if (isDeprecatedGlmtProfileName(profileName)) {
+  const normalized = normalizeDeprecatedGlmtEnv(settingsEnv);
+  // warn user, validate against direct GLM endpoint, continue through settings flow
 }
 ```
