  Bindings identify the concrete cases executed in this file. A compound specification may also depend on
  other registered suites or remain partly proposed; registration is not a passing execution result.

# Tree workflow order and refusal decisions

## Verification Boundary

This suite evaluates local implementation decisions or declarations with controlled inputs. Tree workflow order and refusal decisions defines the scope of its examples.

## What This Suite Proves

The suite executes the concrete examples named by its binding ledger. Those examples contribute to the linked capability or feature scenarios within the boundary of the test assertions.

## What It Does Not Prove

Registration supplies no fresh execution result or deployed conformance verdict. Browser behavior, deployed infrastructure and unasserted variants require separate evidence.

## Real Dependencies and Test Doubles

The tree workflow is real; a recording in-memory store and controlled execution context supply persistence and transaction observations.

## Must Not Be Doubled

The calculation, declaration or workflow decision under examination stays real; replacing it would remove the suite’s verification purpose.
