/**
 * Resolve APK package ownership for a set of candidates on Wolfi/Chainguard
 * images. Each candidate (a single npm package, or a whole Go/Java result) is
 * resolved independently: all of its evidence paths must be wholly owned by one
 * consistent APK package, or the candidate is omitted (fail closed per
 * candidate). Per Chainguard's scanner spec, a dependency with any unowned path
 * is not covered by advisory data and must keep its findings — we skip rather
 * than guess and risk suppressing real vulnerabilities in user-added software.
 * Candidates carrying a coordinate (name@version) are deduplicated, keeping an
 * owned occurrence over an unowned one.
