Claude Code - xff

This repository's agent rules (AGENTS.md) and C++ coding style
(STYLE_CPP.md) are binding. Read and follow both before
writing or reviewing code; STYLE_CPP.md is canonical for C++ (it covers, among
much else: absl::Mutex + full thread-safety annotations, absl::StatusOr and
the MBO_* status macros in production and tests, and gmock matchers).

The files below are imported so they are always in context:
