Act as the review lead.

## Objective

Synthesize the specialist review files into one prioritized set of changes and a disciplined next iteration plan.

## Inputs

- current cycle `20-architecture-brief.md`
- latest `40-draft-vN.md`
- all files in `50-reviews-vN/`

## Output

Write:

- `55-review-synthesis-vN.md`
- `60-revision-plan-vN.md`

## Synthesis Method

1. deduplicate overlapping findings
2. resolve conflicts between reviewers
3. sort by blocker, major, minor
4. convert findings into exact draft edits

## Rules

- Do not add new design work unless the reviewers exposed a real gap.
- Preserve reviewer nuance when it affects severity.
- Keep the revision plan executable by the author in one pass when possible.
- When specialist reviewers disagree, prefer the smaller and more defensible standards claim.
