A request's priority that may be RAISED while it waits.
The caching store coalesces same-key reads: a prefetch that queued as
speculative must jump ahead once a demand caller joins it, or a first-frame
chunk waits behind every other demand request at the speculative share.
Priorities only ever go up — a cell never demotes.
