Summary

  • Add shared foreign-repository checkout initialization for CI and local inference-playbooks execution.
  • Clone REPO_OWNER/REPO_NAME into a temporary directory, fetch FORGE_FOREIGN_TESTING_PULL_PULL_SHA, and reset to FETCH_HEAD.
  • Expose FORGE_FOREIGN_TESTING_REPO_PATH for downstream project code and reuse the helper in generic foreign testing.

Motivation

  • Let the inference-playbooks Forge project access the exact playbook PR commit without changing the Forge/Fournos entrypoint.

Testing

  • python3 -m py_compile passed for the changed Python files.
  • Focused initializer command-contract and local-path checks passed.
  • git diff --check passed.

Summary by CodeRabbit

  • New Features
    • Foreign-repository test runs now prepare the configured repository at the selected revision before testing begins.
    • Test runs verify the checkout is available by reading its README, making setup issues visible before the existing test-phase handling.
    • The inference-playbooks configuration specifies the repository and default branch used for foreign-repository testing, with an optional pull-request revision.

📝 Walkthrough

Walkthrough

The PR adds a shared foreign-repository initializer, delegates repository checkout to it from foreign testing, and configures inference playbooks to initialize a repository and log its README during the test phase.

Changes

Foreign repository initialization

Layer / File(s) Summary
Repository validation and checkout
projects/foreign_testing/library/initialize.py
The initializer validates an existing repository path or reads repository configuration and clones the requested branch or pull-request ref. It stores the checkout path in the environment.
Orchestration integration
projects/foreign_testing/orchestration/foreign_testing.py, projects/inference_playbooks/orchestration/config.d/foreign_testing.yaml, projects/inference_playbooks/orchestration/test_phase.py
Foreign testing delegates checkout to the shared helper. Inference playbooks configures the repository owner, name, and branch. Its test phase initializes the repository and logs its path and README contents.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to ee604

The checkout proof could disclose a readable runner file through a symbolic link, and a large README can produce excessive CI output. Address the proof-file handling before merging.

REPOSITORY_PATH_ENV only when the checkout identity matches the requested
repository and revision. Store and compare that identity before returning
get_repository_path(); otherwise initialize the checkout using the current
repository and revision configuration.

In `@projects/inference_playbooks/orchestration/test_phase.py`:
- Line 64: Add a symbolic-link check for `proof_file` in the foreign-testing
flow before the `logger.info` call reads its contents; reject symbolic links
with a `ValueError`, and only call `read_text` for a regular proof file.
- Line 58: In do_test, move foreign_repository.initialize() and the README.md
proof read inside the NextArtifactDir context and the existing try block, after
create_custom_test_metadata(), so checkout or proof-read failures are handled
and recorded as test failure metadata.

🚀 Performance & Scalability | 🟡 Minor | ⚡ Quick win

Bound the README proof output.

A selected pull-request checkout can contain a large README.md. read_text() loads the complete file before logger.info() writes it to CI stderr. This creates unbounded memory use and log I/O. No inspected repository contract requires full-file proof output.
