• The supervisor run knob. It asked the human to declare an execution checkpoint cadence (low / med / high), stored it, and never enforced it: nothing in scripts/stelow, the stage machine, or a host branched on the value, and no artifact recorded that a checkpoint ever ran. Its only consumer was prose telling the worker to re-check itself against the definition of done, priced by cli-tools/supervise.md at a full headless harness spawn every 3 to 10 tool calls — the most expensive operation this repo describes. Two of the three values told the worker to skip supervision entirely.

Scope close already proves the same work with evidence on disk (test_map, freeze_sha, red_proof, baseline, under red_first), and the parent-controlled loop re-delegates on a failed verify with a fresh context per iteration. So drift has a door that does not need a second model reading prose, and the budget left over stays with the gates that block.

Gone with it: the --supervisor seed flag, stelow_read_supervisor (defined and never called), cli-tools/supervise.md and its references, the cadence/sensitivity tables, the setup question, the spec frontmatter field, WorkflowConfig.supervisor, Stage.supervisor, and StageState.supervisor_active.

States written by earlier versions keep a supervisor: line — readers ignore it exactly as they ignored it before, and a legacy appetite: still maps to the remaining knobs (production, breadth 2/3/5).
