Signed templates had mean AUC 0.7925 versus 0.83625 for energy at 20–500 ms after contact order reversal in eight SEEG sessions
A five-pulse signed waveform template was compared with voltage energy in public STReEF data, OpenNeuro ds005448 v1.0.0. The fixed sample had eight SEEG people and 96 stimulation conditions. One readout per condition was selected from early pulse energies. Both scores used that readout. Five later pulses followed recorded contact order reversal. At 20–500 ms, the equal person mean AUC was 0.79250 for the signed template and 0.83625 for energy. The difference was -4.38 percentage points. The exact two-sided person sign-flip test gave p = 0.421875. A descriptive 95% person bootstrap interval was -12.88 to +1.71 points. The data did not establish a general score difference. Absolute projection had mean AUC 0.82958. The signed-minus-energy contrast was -1.58 points at 100–500 ms. The package preserves selected native voltage, all early candidate energies, pulse scores, four figures, code, source hashes, and replay instructions. All 960 source byte ranges were retrieved and checked. Contact order and time are confounded. Eligibility uses later artifact annotations. These results measure sampled pulse-window separation. They do not certify neural response, continuous detection, or live interface benefit.

The source byte-range extraction code is reused through the cited parent archive. A small change returns all candidate native voltage differences. The source hash checks, channel checks, and voltage scale checks remain in use.

This test uses the fixed 96-condition STReEF archive, exact source range receipts, pinned metadata, and early energy values from the parent Gram matrices. Fresh native voltage retrieval checks those receipts. The package reproduces every early readout choice from the parent data.

The earlier comparison of five-pulse signed templates with energy in ds004696 motivated this transfer test. The current study applies the same type of early energy selection and signed projection to STReEF contact order changes. It adds a separate source result and does not claim a new projection method.
