 * Process-local {@link SessionTokenBudgetStore}: one ledger per
 * `(rootSessionId, rootTurnId)`, no filesystem.
 *
 * It refuses exactly what the disk store refuses (a snapshot for another
 * key, a replaced root account, reduced usage, a forgotten receipt), so a
 * host that tests against one and ships the other sees the same answers.
 * Records are copied on the way in and out, so a caller holding a snapshot
 * cannot change what the store holds.
