What this contract is, and what it is not

A contract, a validation rule, a freshness commitment and a replay path are real mechanisms and they are what this wave builds. more

The last validation read 3,000 records 14 days ago, which is 71% of a single day at the declared volume. A sample proves the shape of what it read and nothing beyond it.
