Name	Type	Description
`pages`readonly	`number`

`bytes`readonly	`Uint8Array`	Every page, back to back. Slot `n` is `[n * pageBytes, (n + 1) * pageBytes)`.
`holder`readonly	`string[]`	Which hash holds each slot, or `''` where it is free.
`decoded`readonly	`boolean[]`	Whether each slot's bytes have been decoded into.
`slotOf`	`Map<string, number>`
`touchedAt`	`Map<string, number>`	Monotonic, standing in for time, so eviction needs no clock. As `table.ts` does.
`clock`	`number`
`frameStart`	`number`	The clock at the start of the frame. Nothing touched after it may be evicted.
`mode`	`DecodeMode`
`decode`	`PageDecode \| null`
