# C293 author review

Question: Does the odd-level arrangement close under the fixed4232 reflection composition?

Conclusion: The common-offset13K arrangement has midpoint4K+i; no complete row closes under fixed8K reflection. Only the opening inner comparison1587/2645 is exact.

The exact results were inspected against the source register and independently expressed domain identities in the checker. The second run verifies deterministic reproduction, not independent scientific review. No new agent review is claimed.

Limits:

- The first inner member is a generated source image, not a historical event at1587.
- No row-dependent comparison axis is adopted.
- The negative result is restricted to common-offset rows.

The report and checkpoint are authored interpretations. The verifier authenticates the supplied inputs and calculations; it does not prove historical intentionality. Original dependencies and all standing controls remain unchanged.
