      - >-
        the change-events consumer delivering receivable facts to Commerce
        (integration)
      - the receiver takes every event
      - >-
        invokes the receiver once, RequestResponse, with the three events of the
        stream
      - 'sends each event as the stream recorded it, with its fact in `after`'
      - acknowledges every message
      - the receiver refuses one event
      - returns the refused event’s message to the queue and no other
      - acknowledges the two events the receiver took
      - reports the receiver’s reason on the failed outcome
      - the receiver answers nothing for one event
      - >-
        returns that event’s message to the queue, never reading silence as
        success
      - the invoke fails
      - returns every message of the call to the queue
      - names the invoke as the cause on each failed outcome
      - returns every message of the call when the function itself failed
      - >-
        acknowledges the same messages when the queue delivers them again and
        the receiver takes them
      - >-
        leaves a message that keeps failing to the queue’s redrive policy: it is
        reported failed on its last receive too

# Commerce financial facts consumer suite

## Verification Boundary

The suite exercises transaction commands and database protections in the local prepared test environment. Registration records the existing executable file; it does not report a run or establish product approval.

## What This Suite Proves

Its cited assertions contribute evidence for configured change delivery retries incomplete acknowledgment. The structured assertion bindings identify which parts of combined scenarios it executes.

## What It Does Not Prove

Local commands and route invocations do not establish deployed routing, live processor guarantees or the complete staff browser experience. An unbound feature chain remains proposed, and this registration carries no execution result.

## Real Dependencies and Test Doubles

The suite uses the imported commands, route handlers or persistence code against the local test database. Fixture helpers supply accounting context; any stepped clock, dummy processor or substituted external client is retained in the evidence declarations.

## Must Not Be Doubled

The command or persistence behavior under assertion and its relevant database protections must remain real. Substituting the final financial result removes evidence of transactional effects.
