A dated dump over [since, until] (ISO dates, inclusive-ish string compare): the document register (journal entries, reversal entries, self-bills — voided ones included, annotated), the void and unused-number records, the open number gaps, the tax-liability rows, and the raw billing events (_GOBD_EVENTS), cut from the event log. since/until filter the raw events by timestamp. The log is append-only by convention, fsynced and backed up — not tamper-evident; integrity in the response says exactly that.

vat_evidence (#1411 R-3): per sale in range, its location-evidence block AS OF until (now, without one) and its trail of changes up to then (vat_evidence_trail); changes after until sit apart in after_range, marked and timestamped. A block filled or contradicted after booking is never shown only as the original failed read. With AGENT_MDX_VAT_LOCATION_EVIDENCE off (no blocks) the key is an empty list.
