HEADROOM, observed, from the rows (ADR-RS decision 22b):
  improvement — probes not right at the default: 7 / 26
  regression  — probes right at the default:     19 / 26

🔴 NO single global value clears the 0-broken bar. Every value that fixes a probe breaks another, which is the pre-registered answer NO — and it is a result, not a failed run.
