Why architecture matters here

Planner v2 fails on unclear budgets and missing eval hooks. Architecture matters because adaptive re-plan without guardrails becomes churn.

The architecture: every piece explained

The top strip is hierarchy. Top-level goal. Sub-goals. Actions. State store.

The middle row is control. Progress signal. Adaptive replan. Budget + termination. Eval hooks.

The lower rows are ops. Human handoff. Observability. Ops — governance + guardrails + audit.

End-to-end flow

End-to-end: user asks 'triage this incident'. Planner decomposes into sub-goals: read logs, ID root cause, propose fix. Actions run. Progress signal shows sub-goal 2 diverging. Adaptive replan refactors. Budget checkpoint. Eval hook confirms quality. Result returned.
