description	Update roquix's packaged openai/codex release. Use when bumping `channel/roquix/packages/codex.scm`, regenerating `channel/roquix/packages/rust-crates.scm` from upstream `codex-rs/Cargo.lock`, fixing `scripts/update-codex.sh` or `.github/workflows/update-codex.yml`, or validating the bump with `guix build` and the existing `verify-guix-pull` workflow.

Update Roquix Codex

Overview

Use the repository's existing updater first. Keep the package files and the automation that maintains them in sync with the current Guix CLI.

Workflow

1. Run the updater from the repository root.
   • bash scripts/update-codex.sh rust-vX.Y.Z
   • Upstream Codex tags use the rust-v... prefix.
2. If guix import fails, fix the local updater and the GitHub workflow together.
   • Current working form:

guix import --insert=channel/roquix/packages/rust-crates.scm \
  crate codex \
  --lockfile="$lockfile"

• Do not reintroduce the older guix import crate --recursive --insert=... form unless Guix changes back.

3. Review the diff.
   • Expected package files: channel/roquix/packages/codex.scm and channel/roquix/packages/rust-crates.scm.
   • Keep the OpenAI Codex release in %codex-release-version. The exported package appends -roquix so Guix selects the channel package when the official Guix package has the same release version. Source tags must use the unsuffixed release version.
   • When changing the updater, make it update %codex-release-version rather than replacing the exported package version expression.
   • If the updater logic changes, scripts/update-codex.sh and .github/workflows/update-codex.yml should change together.
4. Validate package resolution.
   • guix build -L channel -e '(@ (roquix packages codex) codex)' -n
5. Run a full build before closing out the bump.
   • guix build -K -L channel -e '(@ (roquix packages codex) codex)'
   • Expect long logs. cargo install in the install phase can rebuild a large part of the workspace in release mode even after the earlier build phase succeeded.
   • If the build fails in v8 while downloading librusty_v8_release_<target>.a.gz, package the prebuilt archive as an input and set RUSTY_V8_ARCHIVE in a pre-build phase instead of relying on network access from the Guix build sandbox.
6. Validate the channel with verify-guix-pull.
   • Use the existing verify-guix-pull skill for the temporary-profile guix pull check.
   • Keep this skill focused on the Codex bump itself; do not add another project-local guix pull verifier unless the shared workflow becomes unavailable.

Notes

• guix show codex may resolve to the official Guix package instead of (roquix packages codex). Prefer guix build -e '(@ (roquix packages codex) codex)' or module-local checks.
• cargo-build-system can treat a bare origin in native-inputs as a cargo source to unpack. Wrap helper archives that are not Rust crates in a small package instead of passing the raw origin directly.
• If verify-guix-pull reports a package-cache or guix pull failure, treat it as a channel breakage and fix it before closing out the bump.
