Append structured investigation notes to `{state-dir}/perf/investigations/<id>.md`.
Multi-phase performance investigation workflow for establishing baselines, profiling, and making evidence-gated optimization decisions. Use when debugging latency, throughput regressions, or the question "why is this slow?"
Enforces evidence-first debugging for software bugs, incidents, flaky tests, and performance regressions with observation IDs, causality gates, hypothesis tests, and verification rules.
Synthesizes performance findings from baselines, experiments, profiling, and hypotheses into evidence-backed summaries, recommendations, and next steps.
