A model works out and sets up what a project needs on its build VM; code makes sure that happens, bounds it and checks the result (D3). - Before each driver run on a project, one round trip checks the build VM: the harness's own baseline (missing: the item waits, a template problem), the workspace clone (missing: cloned again and said; the item resumes from what it pushed) and a per-project marker. - No marker (a new project, a new or wiped VM): the item's driver model runs a bounded preflight first, with its own prompt, the execution tools (screened as ever) and toolchain_ready. The harness runs each reported version command itself (version-shaped commands only, even from the marker, which the model's commands could edit) and writes the marker. Gaps and an unfinished preflight are facts and work goes on; the thread hears only of installs and gaps. A rebuilt VM starts from the last toolchain. - Later runs check the versions again; a change is a fact and a thread line. The PR body says what the work was tested with. - A changed host key is its own failure (HostKeyChanged): the item waits for the operator's `trust new host key`, which drops the pin; then the VM is set up again. - A prompt line: install what the work needs on the build VM, say why, and put lasting needs in the project's own pins. - tuning.preflight: max_turns, command_timeout_s. - The property walk gains a VM wipe and ready_before_work (checked against a mutant that skips preflight); parked_work_safe accepts that a wipe loses what wasn't pushed (D3).
