Codex fork release harness

This branch contains only the delta used to build the ayanamist/codex fork. It does not contain an upstream Codex source checkout.

Materialize a source tree

python3 scripts/materialize.py \
  --upstream https://github.com/openai/codex.git \
  --tag rust-v0.147.0 \
  --destination /tmp/codex-fork

The command checks out the exact upstream release tag, applies every patch listed in patches/series, then copies files from overlay/. Patches may modify existing upstream files but may not add files. Overlay files may add new paths but may not replace anything upstream. Materialization is atomic: a failure does not leave the requested destination behind.

Validate the harness

python3 -m unittest discover -s scripts/tests -p 'test_*.py'

Pushes that change the harness run the same tests and materialize against the latest official stable release. Push validation never publishes a release.
