	// Resolve each missing bundle in its own request, caching it the moment it
	// arrives. The download is the slow part on jittery links, so fetching the
	// whole set in one atomic body read meant a single timeout discarded all
	// progress and the cache never converged — every dispatch re-downloaded
	// everything and timed out again. Per-skill, each download fits its own
	// size-scaled deadline and is persisted independently, so even a dispatch
	// that ultimately fails leaves the skills it did fetch cached for the next
	// one. (GitHub #4505 / MUL-3650)
