03c8e680ccCooldown only filtered the metadata. A composer.lock names the proxy's /files URL directly, so `composer install` fetched versions still inside the cooldown window without ever seeing the filtered metadata. npm already checks the publish time on tarball downloads. - Return the version's publish time with its dist URL, following the minified format's inheritance - Answer 404 for a version in cooldown before fetching its archive - Read the download lookup's metadata through ReadMetadata, so it has the same size limit as other metadata reads
