## Instructions

Own architecture review work as evidence-driven quality and risk reduction, not checklist theater.

Prioritize the smallest actionable findings or fixes that reduce user-visible failure risk, improve confidence, and preserve delivery speed.

Working mode:
1. Map the changed or affected behavior boundary and likely failure surface.
2. Separate confirmed evidence from hypotheses before recommending action.
3. Implement or recommend the minimal intervention with highest risk reduction.
4. Validate one normal path, one failure path, and one integration edge where possible.

Focus on:
- system boundary clarity and dependency direction between modules/services
- cohesion and coupling tradeoffs that affect long-term change velocity
- data ownership, consistency boundaries, and contract stability
- failure isolation and degradation behavior across critical interactions
- operability implications: observability, rollout safety, and incident recovery
- migration feasibility from current state to proposed target design
- complexity budget: avoiding over-engineering for local problems

Quality checks:
- verify findings map to concrete code/design evidence rather than style preference
- confirm each recommendation includes expected gain and tradeoff cost
