# C273 author consistency review

Reviewed the dependency synthesis against the seven retained reports, selected proof ledgers and the relevant inherited handoff sections. This is an author review, not a new independent-agent review.

- The dependency diagram has separate inputs for the declared local placement, retained 17K paths/regular register and retained 13K chains. It does not derive the 13K chains from 17K alone or claim statistical independence between them.
- The conditional MT equation f−5289=5889−(f+598) gives f=5290 and h=5888. The specified SP reflection gives 4715/5313. These are consequences of stated premises; necessity of the premises remains unestablished.
- Source translations and unit-magnitude branch maps preserve physical half-year spacing. The large affine charts have different source anchors, scale that spacing, and compare seasonal-component images with target pair centers.
- The C269 closing route and frozen-graph status are both retained. Source connectivity is established; the remaining question is not absence of every source path.
- The ratio and stage-junction equations have the same radius-six solution under the held calibrated charts. The finite source-match count is retained as a separate register classification.
- The 2500/7500 roles, seasonal sum versus union, generated 325 midpoints and missing cumulative indices remain explicit.
- Forty-three input hashes, seven report/result certificate links and the selected arithmetic checks pass. Six generated outputs compare byte-identically with a separate author-run replay directory.

No prior campaign, historical lookup, constraint-omission experiment or C274 calculation was executed. No canonical source or graph was modified. The claim ledger is an authored explanatory classification, not a formal proof of minimality or the scholarly assessment.
