Context
The research record preserves failed approaches when they expose a model boundary, an invalid transfer, or an unsupported strengthening.
Proof or evidence
classical bilinear complexity counts products of two input-dependent quantities and discounts additions and multiplication by fixed coefficients.
Verification notes
The failure status and preserved lesson are recorded in the cumulative failure ledger.
Limitations
- keep separate and attribute the rank-to- equivalence to classical tensor theory.
