# NOTE: This package uses a pre-built crate tarball instead of listing individual
# crates in CRATES="". This approach is required because:
# 1. Codex has 800+ crate dependencies, which triggers Portage QA warnings:
#    "QA Notice: This package uses a very large number of CRATES. Please provide
#    a crate tarball instead and fetch it via SRC_URI."
# 2. Stricter ebuild QA checks (e.g., in CI pipelines) fail with too many crates.
#
# The crate tarball is auto-generated by GitHub Actions at:
#   https://github.com/gentoo-zh-drafts/codex/
# Workflow source code for auditing:
#   https://github.com/gentoo-zh-drafts/codex/blob/crate-dist/.github/workflows/crates.yml
# This allows anyone to review and verify the crate packaging process.
