Loop engineering

From lesson 0012. You design who prompts next. You are not Enter.

1. VerifyEvidence in the transcript. Claims are not proof.
2. StopA condition, graded by a checker — not the maker.
3. ScheduleClock, hook, or “not yet.” Starts the next turn.

Not

• Not the inner while-loop (model picks tools). Workflow vs agent.
• Not harness MAX (a count / timeout). Harness card.
• /goal = condition after each turn. /loop = interval. Stop hook = your script.
• Plugins and worktrees wait. You still confirm what shipped.

Anthropic: don’t let the maker declare victory. Claude Code / Cursor both ship the three heartbeats. When this rung is the failure: stack choice.
