🟡 Changes recommended
The updated QA scenario frontmatter introduces a non-standard retest_status value (passed) that appears inconsistent with existing scenario enum usage (pass) and may break tooling that parses these fields.

Pull request overview
This PR fixes a coordinator planning bug where an exclusive route selection could mark dominated outputs as route_not_taken, but the planner would still iterate a stale cloned slice and potentially evaluate a later gate/action from the unselected branch in the same planning pass.
Changes:
- Update control planning to re-load each sorted candidate from the canonical outputs slice before deciding whether it’s still
pending. - Add a regression test ensuring unselected route gates are not evaluated in the same pass.
- Update QA scenario metadata and add a targeted QA run report for the route-selection fix.

What & why
Exclusive route selection updated canonical generation outputs, but the coordinator continued iterating a stale cloned output slice. A later gate or action on the dominated branch could therefore execute in the same planning pass.
The planner now reloads each candidate from canonical state before deciding whether it is still pending. The selected branch executes once; dominated gates/actions remain
route_not_taken; durable route causes and ordering are unchanged.Fixes #528
