  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.

# Large tree edits and competing moves

## Verification Boundary

This suite invokes the local implementation against the prepared database and checks its persisted results. Large tree edits and competing moves 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

PostgreSQL, local Membership services and the suite’s persistence path are real. The business clock and caller fixtures are controlled by the harness.

## Must Not Be Doubled

The Membership path under examination, transaction behavior and database constraints stay real. Replacing those boundaries would remove the persisted proof the suite is intended to supply.
