References — bi-12-debugging-tracing

Primary sources first. In-tree Chromium docs beat any external source, including these modules.

• docs/mac/debugging.md, docs/lldbinit.md in your checkout.
• docs/ tracing documentation; Perfetto UI docs.
• base/trace_event/ — the TRACE_EVENT macros themselves.
• bi-00-roadmap/docs/chromium-build-debug-trace.md — your operational reference.

When a claim here proves stale, record it in PROGRESS.md section 7.
