The implement loop's land stage refuses a lane whose branch has moved past the loop's own records commit, and offers no path for a reviewed follow-up. On 2026-11-01, lane 2 of run-2610312053537139 passed validation round 2. The land stage then wrote its records commit (0030dea82), and a reviewer's note then had to be fixed before the change merged. That fix went on top as two commits, with its own preflight and a delta review pair (SHIP and APPROVE). implement step then refused: the branch is at 764bc6a8dcc3, not at the head 0030dea82032 the landing lands, so restore the branch to that head. Following that remedy would have thrown the reviewed fix away. The lane was pushed and its pull request (#1333) opened by hand with abcd land and gh pr create, outside the run's record. The run's landing state (body_checked, armed) no longer describes the pull request.

The refusal outlives the merge. #1333 merged at 21:28 with both 0030dea82 and 764bc6a8d on origin/main. implement step still refused at land, saying the branch is at 764bc6a8dcc3, not at the head 0030dea82032 the landing lands. Moving the local branch back to 0030dea82, as that remedy asks, produced a second refusal: waiting for its full check, because no preflight receipt names the lane's head 0030dea82032. So recognising an already-merged lane would have cost a full preflight of a records commit, one to two hours on the loaded machine. The preflight was not run, and run-2610312053537139's record stays at land while its work is on main.
