Context
The research record preserves failed approaches when they expose a model boundary, an invalid transfer, or an unsupported strengthening.
Proof or evidence
the verified Run 9 tensor has mode dimensions , so its th tensor power has dimensions rather than the three equal mode dimensions of square matrix multiplication.
Verification notes
The failure status and preserved lesson are recorded in the cumulative failure ledger.
Limitations
- the classical square route needs two complementary BCLR copies to obtain and then three cyclic tensor factors to obtain . Resource recurrences must be attached to that length-1000 certificate, not silently to the five-term partial gadget.
