## Title

    Ledger and rollup need one snapshot

## Body

    Observed symptom: A budget decision from a row-level read paired with a later rollup read can mix two realities. The reusable problem is: Ledger and rollup need one snapshot. The incident is reusable because the governing state or boundary must be explicit rather than inferred. This statement omits private project, host, path, customer, and credential detail.
