An attempt that raised after its edit was committed left the branch on a commit the loop never scored, so the next baseline read the loser. The champion is restored on the way out — and the restore declines when the tree is dirty outside the editable allowlist, because a `reset --hard` that discards somebody else's work to tidy up after ourselves is worse than the mess.
Also: ui/metrics.py brought in line with the house lint, version bumped in all three places it is declared, NAV points at the new entry, and the accumulated [Unreleased] changelog block is released as part of 1.0.1.
750 tests pass (was 748).
