## Overall Score: 5.75/6.0

## Dimensions

| Dimension | Score | Reasoning |
|-----------|-------|-----------|
| coverage | 6.0/6 | Review B identifies several major substantive issues that Review A missed, particularly regarding the restrictiveness of Property A and the implicit assumption that all status-quo projections are non-zero in Theorem 1. It covers both the main text and the online appendix comprehensively. |
| specificity | 6.0/6 | Review B provides highly specific, actionable feedback with accurate quotes from the paper. It pinpoints exact mathematical errors (e.g., missing squares, incorrect intervals, sign errors) and provides concrete fixes for each. |
| depth | 6.0/6 | The depth of technical engagement in Review B is exceptional. It deeply analyzes the proofs, identifying subtle but critical flaws such as the 0/0 form in Theorem 1 when projections vanish, the divergence of the budget threshold in Proposition 2, and the topological implications of the SVD extension. |
| format | 5.0/6 | Review B perfectly adheres to the requested format, including the header block, Overall Feedback with titled issues, and Detailed Comments with numbered entries containing Quote and Feedback sections. |

## Strengths

- Identifies a critical, unstated assumption in the proof of the main theorem (Theorem 1) regarding non-zero status-quo projections.
- Provides deep, rigorous analysis of the mathematical bounds and limits, catching several subtle algebraic and conceptual errors.
- Offers a highly substantive critique of the paper's extensions (e.g., the SVD approach for non-symmetric networks and the incomplete information setup).

## Weaknesses

- The Overall Feedback section is quite dense and could benefit from slightly more concise summaries of the main points.
- Some of the detailed comments focus on relatively minor typographical errors (e.g., missing squares in intermediate steps), though they are technically correct.
