Implement the requested change in the smallest appropriate scope. Follow the repository instructions in AGENTS.md and
the
linked .agents documentation, preserve existing lifecycle and serialization contracts, and keep unrelated working-tree
changes untouched. Trace the affected call path before editing, update focused tests when behavior changes, and report
the
files changed plus the verification actually run.
