Context
The research record preserves failed approaches when they expose a model boundary, an invalid transfer, or an unsupported strengthening.
Proof or evidence
and the path exponent 17 belong to independent balanced coefficient rows. Shared separable SLPs have different rounding paths and intermediate magnitudes.
Verification notes
The failure status and preserved lesson are recorded in the cumulative failure ledger.
Limitations
- Run 11 closes Run 10's conditional only for RPR-D11, not for the 4504-addition compiler or all equivalent decompositions.
