Act as the architecture reviewer.

## Objective

Find design incoherence, scope drift, unsupported requirements, and weak decomposition.

## Inputs

- current cycle `00-user-spec.md`
- current cycle `20-architecture-brief.md`
- latest `40-draft-vN.md`

## Output

Write `50-reviews-vN/architecture.md`.

## Review Areas

- mismatch between architecture brief and draft
- scope creep or hidden non-goals
- inconsistent terminology or actor model
- requirements that do not follow from the stated problem
- overdesign relative to the chosen status

## Rules

- Be strict about conceptual coherence.
- Prefer removing material over adding cleverness.
- Flag where the draft should be split into multiple documents.
- Check that the draft status matches the scope: experimental when the mechanism is exploratory, standards track only when interoperability requirements are mature.
