# /sdlc-arch-review — Architecture Review

1. Read the run's `specs/architecture.md` and `system_design.json` (via `sdlc_spec` `action: read`).
2. Review against: requirement coverage (trace each requirement to a component), failure modes (what breaks first under load/partition/restart), boundary clarity (who owns which state), security posture (trust boundaries named), and cost drivers.
3. Output: strengths, severity-ranked concerns with the specific section cited, and questions the design must answer before stage 07.

## RStack governance routing

Approval or rejection of the architecture goes through `sdlc_approve` (`artifact: architecture.md`) — this command writes nothing.
