Use when the user wants architecture-first product and system design with explicit stack rationale, boundaries, tradeoffs, data model choices, and phased delivery planning.
Use when the user wants to decide whether implementation is ready, what remains blocked, and what the exact next build step should be.
Use when the user wants logic validation: states, transitions, invariants, edge cases, dead ends, and blockers before implementation.
Use when the user wants evidence-backed technology choices, OSS evaluation, and source-grounded validation of the stack proposed in `$arch`.
Use when the user wants a security and trust-boundary review of the current design before implementation or release.
Use when the user wants a DX and UX review of the planned workflow before implementation proceeds.
