 **`@objectstack/metadata-core`.** `ArtifactForwardConversionVerdict` gains `'converted-retired-after'`: the floor is at or above the runtime label, but at or below the `retiredAfter` of at least one retired entry, and only those entries are replayed. A consumer that switches exhaustively over the verdict adds that arm. The door's operator log lines are unchanged: one summary per conversion per artifact, naming the site count.

Run it after each stable publish.
