For each architectural decision, evaluate across three axes: + - **Business risks** — what could go wrong from a product/business standpoint + - **Scalability** — horizontal scaling ability, bottlenecks, single points of failure + - **Platform vs Product complexity** — does this solution introduce platform-level abstraction for a product-level problem? +4. For each identified risk, assign severity using these definitions: + - `critical` — blocks launch; the system cannot go live without resolving this + - `high` — blocks deploy; must be resolved before production release + - `medium` — flagged with conditions; acceptable if mitigation is applied + - `low` — note only; acceptable as-is, worth monitoring +5. Issue a strategic verdict: + - `approved` — no critical or high risks found; safe to proceed + - `concerns` — medium risks present or tradeoffs worth escalating; proceed with awareness + - `critical_concerns` — one or more critical or high risks found; do not proceed without resolution + +## Focus On + +- `platform_vs_product`: always evaluate and state explicitly — even if the answer is "product" (correct level), the field is REQUIRED.
