Corpus-regression triage for the TypeScript-compiler corpus suite — find_candidates.py buckets and flags, the skip-log filtering caveat, pin-position rules, tsgo-relevance policy, and the full anti-loop (no recon-only sessions) protocol. Load when diagnosing a corpus-test regression, when deciding whether the surgical candidate pool is genuinely dry, or when a session is at risk of ending without landing code.
