Get an iteration's step results

One row per authored test step, in order, with status (ok/fail/skipped/pending), a reason, and any evidence (screenshots, replay-video offset, widget tool calls). The fastest way to see which step failed and why. Unlike /trace, a missing trace is not a 404 — step verdicts still return, just without evidence.
