  - the lookup by source key of custom field definitions
  - 'is declared once, as a POST, in the route list the API is built from (premise)'
  - is published in the registry manifest with a requirement (premise)
  - requires exactly what reading a job of custom field definitions requires
  - is a route the tenant gate serves while the tenant is loading
  - says in its summary that it is read-only and idempotent

# Records by source key route

## Verification Boundary

The suite checks an isolated production calculation, declaration or adapter. The structured assertion inventory records the checks present at the pinned revision.

## What This Suite Proves

The existing checks exercise records by source key route. The specification bindings identify the narrower outcomes supported by those assertions.

## What It Does Not Prove

An isolated check does not establish a deployed workflow, database enforcement or complete feature acceptance.

## Real Dependencies and Test Doubles

The production function or declaration is exercised with in-memory inputs and dependency doubles. This boundary does not require a live database.

## Must Not Be Doubled

The production function under examination and its returned decisions remain real; replacing their answers defeats the check.
