The staged-bytes seed left the transient half of the working set to a
guessed multiplier, and that half scales with the running workload rather
than the model topology. Track the largest cached-but-unallocated value
observed at any component boundary instead: the budget is the larger of
the seed and the observed peak times a 1.25 margin, still capped at a
quarter of device capacity. A workload that outgrows the seed pays one
release while the observation lands, then retains steadily. No warmup
flag is needed and no user-chosen fraction exists.
