    Variable PLAN_MEMO_MSConst

    PLAN_MEMO_MS: 60000 = 60_000

    How long an isolate reuses a resolved plan before reading KV again.

    KV free allows 100,000 reads/day, the same order as the Worker-request ceiling, so a read per request would spend one binding meter to consult another. One read per isolate per minute is nothing, and an upgrade that takes up to a minute to apply everywhere is the right trade for a value that changes about once in a site's life.
