## Summary Add a server-owned `recencyAt` timestamp and `recency_at` thread-list sort key for product recency ordering while preserving the existing meaning of `updatedAt` as the latest persisted thread mutation. This is the server-side alternative to #27697. Rather than narrowing `updatedAt`, clients can sort the sidebar by `recency_at` and continue treating `updatedAt` as mutation time. Paired Codex Apps PR: [openai/openai#1024599](https://github.com/openai/openai/pull/1024599) ## Contract - `recencyAt` initializes when a thread is created. - A turn start advances `recencyAt` monotonically. - Commentary, agent output, tool results, token/accounting updates, turn completion, archive, unarchive, resume, and generic metadata writes do not advance it. - `updatedAt` retains its existing behavior and continues to advance for persisted thread mutations. - Current servers populate `recencyAt`; the response field is optional in generated TypeScript so clients connected to older servers can fall back to `updatedAt`. - Filesystem-only fallback uses existing updated/mtime ordering when SQLite is unavailable. ## Persistence and compatibility Migration 0038 adds second- and millisecond-precision recency columns, backfills them from the existing updated timestamp, creates list indexes, and includes an insert trigger so older binaries writing to a migrated database seed recency without causing later mutations to advance it. Generic metadata upserts preserve existing recency values. Turn-start updates use a dedicated monotonic touch, and process-local allocation keeps millisecond cursor values unique. State DB list, search, read, filtered-list repair, rollout fallback propagation, and app-server conversions all carry the new field. ## API `Thread` responses include: ```ts recencyAt?: number ``` `thread/list` and `thread/search` accept: ```json { "sortKey": "recency_at" } ``` Generated TypeScript and JSON schemas are included. ## Validation - `just test -p codex-state` — 146 passed - `just test -p codex-rollout` — 69 passed - `just test -p codex-thread-store` — 81 passed - `just test -p codex-app-server-protocol` — 231 passed - Focused app-server list ordering, response mapping, archive/unarchive, and resume lifecycle tests passed - Scoped `just fix` for state, rollout, thread-store, app-server-protocol, and app-server - `just fmt` - `git diff --check` - Independent correctness, simplicity, elegance, security, and test-quality reviews; actionable ordering, lifecycle, query-projection, and timestamp-uniqueness findings were addressed
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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# 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.
