Crossing
The fare is words of proven retention, checked against manifests. One taught word per dawn does not guarantee one retained at audit. The Rate shows lending among eleven people at the bank, an audited crossing and a later rise to three hundred. The names charge of one hundred has no explicit unit in that sentence.
The paid voice
In The Last Word, two recorded words earn money. The money helps the mother, but cannot simply buy the father's missing retained words. A copy of the first take costs half the fee. A breath can move while the accepted number remains the same. These are linked economies, not interchangeable tokens.
Continuation
A continued voice, a recording, a standard version and a living memory are treated differently. Export makes that distinction at the border. The receipts record payment rather than the unrecorded marriage. Warmth and accurate habits can be wanted, refused and wanted again without proving who inhabits the service.
Local exemptions
The maternity grace period is free, but recorded. Children cannot be fined for listening to the cat; that does not abolish charges around birth or school. The later finding records no charge for the interruption; the hour is marked unavailable for query, yet a schedule holds statements about it. Scope belongs to each provision.
