Development record

The lab chapter's exit codes say exit 1 covers a gate that refused (the preflight, the sweep, the harvest's citation check) or a halted lab refusing a probe, 'with the artefact rendered and the finding recorded' (.abcd/development/brief/04-surfaces/31-lab.md:175-176). That holds for the preflight and the sweep only. The harvest's citation refusal writes nothing, as lines 169-171 of the same chapter say, and sets no halt; `lab record` on a halted lab writes nothing and names the standing finding.
