Individual repositories in the advisory population raise per-candidate
extract.InstrumentFailure during extraction (git_exit_128 on an
unfetchable fix commit, clone_size_cap, and others), and each one
aborted the whole 300-repo draft. The draw is healthy; one bad repo
should not reset it.
extract_repository now also catches extract.InstrumentFailure and
OSError and records them as "extract_<reason>" rejections, so the draw
skips that repo and continues (the reason, e.g. extract_git_exit_128,
shows in the rejections counter). ExtractionTimeout keeps its existing
extraction_timeout skip; any other exception still propagates as a real
abort, so genuine code bugs are not masked.
A systemic guard preserves the instrument rule: run() raises
InstrumentFailure("systemic_extraction_failure") if 25 extraction
attempts fail with zero successes (e.g. git missing, auth broken) or if
extraction failures exceed 200 overall. A handful of bad repos with many
successes never trips it.
190 unseen tests pass, ruff clean.
