4211 — Computational Grammar Census Requires a Joint Parent-Detail Readout
Claim
The admitted audit classifies all 33 defined functions and methods in retained_path_successor.py and all 25 named definitions in ComponentArithmetic.agda, recording constructors, recursive equations, guards, readouts, and the native-bridge boundary. In the checked retained-path model, the nonzero sibling contrast has zero average. The ambient averaging decoder therefore cannot serve as the compare-kind equivalence datum on the full child space. The joint parent/detail map is reversible; the decoder is an inverse only on the copy image. The report also records exact split/reassembly and ancestor-encoding checks, retained operands and cuts, and distinct assembly trees for associative readouts.
Scope
This is a source-bounded computational and structural audit, not an operational interpretation of retained-path operations into native Resolve. The native arithmetic bridge is separately checked, but the nine-row policy/native interpretation and path Resolve bridge remain open. Global grammar coverage, S4 generation, and physical dynamics are not claimed.
