        a timeout as a request limit the caller can act on, naming no SQL

        any other failure with a generic server error, never the statement, its tables or a criterion value,

# Platform read only execution

## Verification Boundary

The file invokes its service or persistence boundary against local integration fixtures.

## What This Suite Proves

Its assertions check read only execution. The assertion bindings identify the corresponding acceptance examples and retain their original test-title citations.

## What It Does Not Prove

Local execution does not establish deployed queue scheduling, every external provider response or a passing result at the pinned revision.

## Real Dependencies and Test Doubles

The integration fixture and any imported dependency seams define the environment. Database-oriented checks use PostgreSQL; file-owned transport, clock, provider or worker seams isolate the explicitly controlled boundary.

## Must Not Be Doubled

Keep the service or persistence operation whose behavior is asserted real. Database constraints and transactions cannot be replaced by fixture answers when they are the subject of the check.
