The prober names 6% of the unnamed releases it finishes and the pending queue (44M) grows eleven times faster than it probes. A sample of 44,530 finished pending rows shows the headers predict a name: size bucket, name shape, completeness, tool and group separate 0% classes from 95% ones, while the learner keyed on tool and group alone (LOG.md (130)). - lib/release/classes.ts, names::pending_class, SQL pending_class(): a release's class (size × shape × partial, 1..70), the three in step. - Migration 6800: pending_releases.klass and target_bytes (the first target's article; candidates carry bytes now), pending_classes with each class's climbs, names, waiting and verdict, the claim's index. - The ladder claims the classes with the best record first (a prior for the unexplored, at most a quarter of a claim from one), the cheapest target first within one, then the oldest of the rest; records classes like signatures and drops them at the same thresholds; discards their waiting releases. Claimed rows sorted in code: an UPDATE returns none. - The rule set's droppedClasses: the edge keeps unnamed releases of a dropped class out of the pending store (counted as garbage), the explored sample excepted. - hash_twins.ts: a probed file whose first 16 KiB and size match a named catalog release's names a pending release the probe didn't, and sets the inner name of a catalog release without one. - pending:classes classes the rows from before and seeds the record from the finished ones; rules:classes publishes the dropped classes; releases:readable also marks the rows' candidates unreadable.
