A sixth result dimension. Versions parsed from httpx tech strings and Server headers match against a local NVD corpus, so an asset's known CVEs are named without sending a request. The stored CPE is not the input: 81 of 7,771 entries carry a version, so matching on it returns every CVE ever filed against the product. Versions come from tech and the Server banner, and the NVD pair comes from a curated map rather than a name match — popper:popper is a 2005 webmail app, aos is a switch OS, and Apache's CVEs live under apache:http_server, not apache:apache_http_server. An unmapped product is reported as unmapped. Ranges compare as zero-padded keys so the match is one SQL pass: a letter suffix takes its own segment, trailing zeros drop, and numeric and alphabetic schemes never order against each other. A criteria with no version statement is discarded at load, because it means every release. Measured against a reference implementation over 3,000,000 comparisons, residual disagreement is 0.07% and each case is the new rule being the correct one. Every match names what is unverified — conditional, backport, fingerprint, coarse — and confidence is the count of those. Nothing inferred enters the vulnerability count, triage or coverage a scanner earned; software_cves keeps its own. The corpus is a fourth feed, keyless, from the fkie-cad mirror of the retired NVD JSON feeds: 2,197,146 ranges and 372,244 CVEs in 5m40s, streamed rather than parsed whole (1,254 MB resident becomes 86 MB). It rebuilds nightly and re-matches every covering scan, since the corpus moves without a scan. Exploitation coverage and the intel change feed leave Arsenal for the dashboard; Arsenal keeps the feeds and the provider it configures. Feed row counts, nouns and tables now come from FeedSpec — three places had hardcoded two kinds, so a third feed rendered 0. Port versions split out of the Server header in the migration: 223 rows become 3,037.
