# Maintain partitions

## Verification Boundary

The suite checks the production service or shared engine against its database fixture. The structured assertion inventory records the checks present at the pinned revision.

## What This Suite Proves

The existing checks exercise maintain partitions. The specification bindings identify the narrower outcomes supported by those assertions.

## What It Does Not Prove

Local execution does not establish deployed queue, storage or service behavior. Independent test cases do not establish a complete cross-feature process.

## Real Dependencies and Test Doubles

Real Postgres executes the partition helpers and catalogue reads. The fixture supplies an archive callback, a fixed clock and telemetry spies.

## Must Not Be Doubled

The database effects, security context and production operation under examination remain real. Their outcomes cannot be replaced with canned success responses.
