# Snapshot persistence and payload refusal

## Verification Boundary

The suite checks its declared service or persistence boundary against local PostgreSQL. Bindings identify the assertions it contributes to a capability case; they do not establish every assertion in a combined case.

## What This Suite Proves

The snapshot suite preserves supplied captured documents and tests database refusal of invalid references, duplication, oversized objects and prohibited updates.

## What It Does Not Prove

This register records assertion scope without claiming a passing run or complete coverage of every rule and scenario variant.

## Real Dependencies and Test Doubles

Production persistence and mapping run with application-role transactions and workspace policies on PostgreSQL. Fixture records and fixed context values supply the inputs; the service and database enforcement under assertion remain real.

## Must Not Be Doubled

Keep production queries, writes, mappings, application-role privileges and database constraints real wherever they are the subject of an assertion. Recording financial ports establish invocation behavior; actual recognition and reversal require the suite using the real posting service.
