  Use the file’s run-owned input objects and test doubles; restore changed environment values and
  installed dependencies after each case.

    Static review at the recorded source revision; executable results remain not-run and conformance
    remains not-verified.

  The file exercises its imported production code with controlled inputs. Source inspection
  identifies the test entry and assertions; it does not establish a live database, provider or
  deployed workflow.

  The file has no scenario binding established by this examination. Its executable checks remain
  registered without assigning them broader acceptance coverage.

# Caches unit checks

## Verification Boundary

The file evaluates production helpers with controlled inputs in-process. The assertion references identify the source checks for caches.

## What This Suite Proves

The file supplies executable engineering checks for the named subject. No complete acceptance scenario is inferred from the file’s existence.

## What It Does Not Prove

This examination does not run the suite. Passing behavior, deployed conformance and the behavior of substituted dependencies require separate execution evidence.

## Real Dependencies and Test Doubles

The file exercises its imported production code with controlled inputs. Source inspection identifies the test entry and assertions; it does not establish a live database, provider or deployed workflow.

## Must Not Be Doubled

Keep the production helper, schema, matcher or declaration under examination real. Substituting the decision itself would remove the behavior the assertions exercise.
