pub fn classify(
cache: &HashMap<String, CapabilityState>,
verdicts: &HashMap<String, bool>,
servers: Vec<String>,
size_bytes: u64,
) -> Vec<String>Expand description
Pure tier-classification (DB-free, unit-testable). Reorders into informed-yes → known-good → unknown → too-large → MIME-rejected → informed-no, stable within tier.
verdicts is what a server’s own information document says about this
size for this account. A server that has told us outranks one we have
only learned by bouncing uploads, and one that has told us no goes last:
its preflight would only confirm it.
