## Why `/status` was showing the configured `ModelProviderInfo.base_url` for Amazon Bedrock, which can be stale or misleading because the actual Bedrock Mantle endpoint is derived at runtime from the resolved AWS region. This made sessions report the wrong provider endpoint even though requests used the correct runtime URL. ## What changed - Added `ModelProvider::runtime_base_url()` so provider implementations can expose the request-time base URL through the shared runtime provider abstraction. - Moved Bedrock region-to-Mantle URL resolution into `amazon_bedrock::mantle::runtime_base_url()`, keeping region resolution private to the Mantle module. - Overrode `runtime_base_url()` for Amazon Bedrock so it returns the resolved Mantle endpoint instead of the configured default. - Resolved and cached the runtime provider base URL during TUI startup, then used that cached value when rendering `/status`. - Added status coverage that verifies Bedrock displays the runtime URL and ignores the configured Bedrock `base_url` when they differ. ## Verification model provider is resolved correctly in local build: <img width="696" height="245" alt="Screenshot 2026-04-29 at 5 01 36 PM" src="https://github.com/user-attachments/assets/a13c10a5-3720-41ab-8ace-3c4bc573f971" />

Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
