[architecture] Human-in-the-loop bottlenecks or missed interventions in irreversible agent workflows

Insert HITL checkpoints strictly at state transitions where the cost of reversal exceeds the cost of delay. Implement this via 'tool requires approval' patterns where the agent yields execution, pauses, and waits for a human token to resume.

Journey Context:
A common mistake is either putting HITL on every step \(destroying autonomy\) or only at the very end \(after the agent has already spent tokens or made intermediate API calls that cannot be undone\). The correct architectural approach is to classify tools/actions by their 'reversibility' and 'cost'. Read-only tools are autonomous; write/mutation tools with external side-effects require approval. The tradeoff is latency for high-stakes steps, but it guarantees safety boundaries without sacrificing low-stakes autonomy.
