Context
The research record preserves failed approaches when they expose a model boundary, an invalid transfer, or an unsupported strengthening.
Proof or evidence
Run 7 pins every child input and requires a fresh output. Run 8's sharp compiler permits a last-use generated temporary to transfer its register to the child; raw values and root inputs remain protected.
Verification notes
The failure status and preserved lesson are recorded in the cumulative failure ledger.
Limitations
- retain the pinned-reset formulas as a separate baseline and label the ownership change explicitly.
