# NAMING: the package is dev-util/codex-desktop-bin, but everything upstream
# ships is called "chatgpt" -- the Debian package name, the payload directory
# (/usr/lib/chatgpt), the launcher symlink (/usr/bin/chatgpt) and the .desktop
# entry. This is not a mistake: OpenAI unified ChatGPT, ChatGPT Work and Codex
# into a single desktop app whose Linux build is published under the Codex
# brand (HOMEPAGE is developers.openai.com/codex/app, the APT repo is
# codex-app-prod, the internal launcher is called codex-launcher). We keep the
# "codex-desktop" name so the package sits next to dev-util/codex (the Rust
# CLI) and dev-util/codex-bin, and we keep the "chatgpt" command name so that
# the upstream .desktop entry, the x-scheme-handler/codex handler and any
# documentation that says "run chatgpt" keep working.

# Upstream ships only .deb (the /rpm/ path of the same CDN 404s). Always use
# the versioned pool URL: .../deb/latest/chatgpt_amd64.deb also resolves but is
# a moving alias and therefore unusable as a distfile.
