  The production decision runs in-process. The suite substitutes the clock, registry reads where its

  The file has no scenario binding established by this examination. Its executable checks remain

# Manifest throttling unit checks

## Verification Boundary

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

## 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 production decision runs in-process. The suite substitutes the clock, registry reads where its dependency setup supplies them; those boundaries have no live-service proof here.

## 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.
