test_no_pair_repeats_a_repository_the_benchmarks_already_name failed: advisory-fix
catalog repos also appeared elsewhere under benchmarks/. Root cause split two ways:
1. Genuine leak: 16 catalog repos are also subjects in benchmarks/search/private/
pilot.json (a real private pilot population). Removed those 16 pairs from the
three catalogs and their verification.json rows (totals recomputed, catalog ==
verification preserved).
2. Spurious: the overlap scan greped ~49k vendored files under
benchmarks/search/private/runs/*/checkout/node_modules/, so any catalog repo a
vendored dependency's README names collided. Added a narrow vendored-tree skip
(node_modules/vendor) to the scan rather than deleting labelled pairs over a
dependency mention.
Implemented from Codex's first pass (gpt-6.1-sol), then gated and corrected: Codex
removed 20 pairs; 4 of those (backstage/backstage, koajs/koa, beaugunderson/
ip-address, cakephp/cakephp) were driven only by vendored/non-population mentions
and are kept. Also excluded advisory-fixes-spread.json (catalog-derived report)
and research-2026-09-26.md (selection write-up) as non-population.
tests/test_advisory_fix_pairs.py + tests/test_learn_labels.py: 53 passed.

97 advisory-fix pairs, one repository each (309 advisories examined, 212
rejected with reasons in research-2026-10-01.md): a public fix commit
distinct from its parent, the advisory-named function declared on both
sides with a changed body. Pointer pairs: materialize.py reads one file
per side from a shallow blobless fetch into the pair cache and verifies
them with the label builder's matcher (verification.json, bytes read).
learn/sources.toml lists the catalog as the advisory-fixes source. Label
snapshot: negative repository groups untrusted_destination 8->25, path
3->21, output_encoding 1->22, deserialization 0->21, access_control 0->20;
all five reach the per-family floor. Five pairs on reserved repositories
were dropped after the reserved-population guard flagged them.
