## Why The generated unnamespaced JSON envelope schemas (`ClientRequest` and `ServerNotification`) still contained both v1 and v2 variants, which pulled legacy v1/core types and v2 types into the same `definitions` graph. That caused `schemars` to produce numeric suffix names (for example `AskForApproval2`, `ByteRange2`, `MessagePhase2`). This PR moves JSON codegen toward v2-only output while preserving the unnamespaced envelope artifacts, and avoids reintroducing numeric-suffix tolerance by removing the v1/internal-only variants that caused the collisions in those envelope schemas. ## What Changed - In `codex-rs/app-server-protocol/src/export.rs`, JSON generation now excludes v1 schema artifacts (`v1/*`) while continuing to emit unnamespaced/root JSON schemas and the JSON bundle. - Added a narrow JSON v1 allowlist (`JSON_V1_ALLOWLIST`) so `InitializeParams` and `InitializeResponse` are still emitted. - Added JSON-only post-processing for the mixed envelope schemas before collision checks run: - `ClientRequest`: strips v1 request variants from the generated `oneOf` using the temporary `V1_CLIENT_REQUEST_METHODS` list - `ServerNotification`: strips v1 notifications plus the internal-only `rawResponseItem/completed` notification using the temporary `EXCLUDED_SERVER_NOTIFICATION_METHODS_FOR_JSON` list - Added a temporary local-definition pruning pass for those envelope schemas so now-unreferenced v1/core definitions are removed from `definitions` after method filtering. - Updated the variant-title naming heuristic for single-property literal object variants to use the literal value (when available), avoiding collisions like multiple `state`-only variants all deriving the same title. - Collision handling remains fail-fast (no numeric suffix fallback map in this PR path). ## Verification - `just write-app-server-schema` --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

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.
