description: ARS /ars-cache-invalidate — drop cached verification entries for a citation key model: sonnet

Invalidate the persistent verification cache for one citation key, so the next pipeline run re-verifies it live against Crossref / OpenAlex / Semantic Scholar / arXiv instead of returning a stale cached verdict. Use this when a citation's metadata changed (e.g. a preprint gained a published DOI) or when a prior verification looks wrong.

The cache (spec v3.11 #182 Delta 2) is a local SQLite store at ~/.cache/ars/verification.db (override via ARS_VERIFICATION_CACHE_PATH), keyed by (citation_key, resolver_name, query_form) with a 90-day TTL. This command removes every cached entry for the named citation key (all four resolvers, all query forms); other citations are untouched. It is idempotent — invalidating a key with no cached rows succeeds as a no-op.

To invalidate the entire cache at once (e.g. after a systemic resolver bug cached many false negatives), delete the database file directly: rm ~/.cache/ars/verification.db. It is recreated empty on the next run.

Implementation:
