[synthesis] Letting AI agents run to completion without intermediate verification

Architect agent loops with explicit verification checkpoints: after each discrete step, force the agent to validate its output \(compile, test, diff review\) before proceeding to the next step.

Journey Context:
The naive agent loop is plan → execute → done. LLMs compound errors within a single unbroken generation: one wrong assumption cascades into increasingly divergent output. Devin's public demo shows explicit 'milestones' where it stops to verify its work against the task. Cursor's agent mode shows diffs for approval before applying. The pattern: plan → step 1 → verify → step 2 → verify → ... → done. The tradeoff is latency — checkpoints add round-trips. But without them, error recovery requires full re-generation, which is slower and more expensive. Verification is cheaper than re-generation.
