**Peer Review: A Haskell Reference Semantics for CatDB Schema Mappings (Correction Round)**

This manuscript successfully incorporates all feedback from the prior review round. The authors have meticulously corrected the arithmetic inconsistencies and type inaccuracies, and have clearly disambiguated the expansion of the corpus in the unreviewed Slice 5 candidate. 

### Resolution of Round One Findings:
1. **QuickCheck Trial Sums:** Fully resolved. The arithmetic for the QuickCheck trials has been accurately updated to 1,550 across the abstract, tables, and body text, reflecting the correct sum of the seven deterministic properties (250+250+250+200+200+200+200).
2. **Haskell Listing Type Accuracy:** Fully resolved. Listing 1 now perfectly reflects the Haskell type semantics. The unused `arrows` parameter has been removed from the signature, and the implementation correctly uses `fmap path_arrows . lookupArrowImage mapping` within `traverse` to extract arrow lists from the monadic context before applying `concat`. The accompanying text accurately explains this traversal mechanism.
3. **Slice 5 Cases Clarification:** Fully resolved. Section 8.4 explicitly clarifies that the working-tree candidate adds exactly nine new fixtures (five information-loss and four schema-diff), correctly expanding the corpus to a total of seven information-loss cases and six schema-diff cases.

### Re-Audit of Core Criteria:
- **Technical Correctness & Haskell Semantic-Oracle Boundaries:** The mathematical notation for path and mapping composition is sound. The boundaries of the Haskell semantic oracle are transparently defined, acknowledging that it is a reference evaluation over a bounded profile rather than a complete mathematical proof or production backend.
- **Slice 2 vs. Slice 4 vs. Slice 5:** The snapshot discipline in Sections 2 and 8 is outstanding. The manuscript cleanly separates the historical accepted baseline (Slice 2) from later accepted extensions (Slice 4) and unreviewed working-tree code (Slice 5).
- **Expected/Actual Independence:** Section 6 and the threat model in Section 10 clearly establish how the Rust and Haskell processes remain decoupled and how semantic actual outputs are kept independent of the expected golden values during evaluation.
- **Package Naming:** The transition of the Cabal package name from `catdb-reference` to `catdb-semantics` is well-documented and historically accurate, ensuring the reproducibility contract remains unambiguous.
- **Prior Art, Citations, & Readability:** The prior art appropriately frames the contribution within existing categorical database literature. The LaTeX formatting, figures, and structure maintain excellent arXiv-style readability.
- **Reproducibility, Overclaiming, & Limitations:** Section 11 provides a comprehensive and honest list of 28 exact nonclaims, strictly bounding the capabilities of the reference semantics. The reproducibility contract in Section 12 provides a robust guide for historical reconstruction.

The manuscript meets all criteria for rigorous systems reporting and provides a highly transparent, reproducible artifact. There are no remaining major or minor issues.
