limit is PREFILL_ON_SAVE's cap, which still bounds the queue rows of a single save.
The lazy branch is safe only when stale is true: an unqueued page is served from its previous
KV generation (readStalePage(), which needs PAGE_KV, unbound in the canonical config). With
no stale tier the pages are queued for the alarm chain instead.
Picks the policy for one invalidation.
