#!/usr/bin/env python3
"""Prepare one corpus repository for LocalSandbox validation and write bootstrap.json.

Replaces Repo2RLEnv's Docker-based `ensure_bootstrap` (bootstrap/runner.py line 471
requires a daemon). Produces the same BootstrapResult shape that
bootstrap/cache.py line 117 loads.

Steps
  1. sandbox checkout: `git clone --shared` of the local mirror, detached at the pinned SHA
  2. `.venv` inside the checkout (excluded by the stage script's `git clean -e .venv`)
  3. install: editable package + test extras + requirements files + pytest
  4. verify: pytest collection, then a bounded full run
  5. write bootstrap.json, requirements.lock, report.json

Usage:
  bootstrap_repo.py --repo owner/name --sha <pinned> [--python 3.12] [--extra-pkg X ...]
                    [--install-cmd "<shell>"] [--test-cmd "python -m pytest"] [--suite-timeout 1200]
Exit code 0 even when verification fails; read report.json / the printed summary.
