Verdicts

Every replay ends in a verdict. Verdicts are evidence, not commands — they summarize what the replay showed so you can decide, and they’re recorded in the evidence ledger.

VerdictWhat it meansSuggested action
Fix VerifiedThe candidate fix resolved the failure and didn’t break sibling traces in the clusterSafe to ship; promote to the regression library
Fix RegressesThe fix either didn’t resolve the failure, or resolved it while breaking another traceDon’t ship; revisit the fix
UncertainThe evidence isn’t strong enough to call — often the original failure didn’t cleanly reproduceGather more traces or make the repro deterministic before deciding

Lumni would rather say “I can’t prove this” than give you false confidence. An Uncertain verdict usually means one of:

  • The failure was flaky or environment-dependent and didn’t reproduce.
  • The replay bundle was missing inputs needed for a faithful re-run.
  • The fix changed behavior in a way the comparison can’t cleanly attribute.

Treat it as a signal to improve the repro, not as a soft pass.
