A fix round that rebases the lane branch leaves the lane receipt's resolves[].commit at the pre-rebase sha, which is no longer reachable from the lane head, so the landing would stamp an unreachable resolved_by.commit that RS003 refuses at preflight. Met overnight on run-2610072316033117 (fab3f1704 rebased to 90f48d5f9); corrected by hand in the run state.
