5-task plan for the boss-signed spec docs/specs/0067-r-sweep-followups.md. Task 1 adds RMetrics.sqn_normalized (+ SQN_CAP + summarize_r compute) and threads all four RMetrics struct literals (compile-gate). Task 2 adds the Metric::SqnNormalized rank key. Task 3 re-baselines the 0066 single-run golden (the r: block gains the field). Task 4 wires --trace for the stage1-r sweep (invert the refusal test → persist member dirs via persist_traces_r, drop the run_sweep guard). Task 5 is the full-workspace gate. Sequencing pins the golden re-pin and the unfiltered suite after Task 1. refs #130, refs #135
