Freeze a Bisect SHA and Public API Before an OSS Patch Review
Maintainers must freeze two artifacts before model-assisted OSS patch review: a `FIRST_BAD` file containing the git bisect SHA (found via `git bisect run pytest tests/test_parse.py::test_empty_header -q`) and an `api.snap` snapshot of top-level public names extracted via AST, with `allowed_files.txt` (from `git diff --name-only`) as the sole permitted edit set. These hard merge gates prevent models from inventing extra files, expanding public APIs, or widening scope beyond the reproduced bug; flaky bisect runs halt the workflow until the test harness is fixed.

score
score 8 out of 10. 0-10: how dense the facts are, multiplied by how much you can do with them after reading. 8+ means the topic's evidence bar is met: benchmarks and availability for a new model, amount and investors for a funding round, revenue figures for a solo-money story. Below 5 an item does not enter the digest. A press release scores 3 or less, a reprint loses 2, anything older than 14 days loses 1, a headline that misleads loses 3.
