rewind changes did not regress the baseline.
+- **Physical-backend milestone (2026-10-01)**: the module-owned GPU path
+ reached the first successful secure-verification (FWSEC) carve of the
+ protected region on the real TU104 under the verified D0 power-domain
+ harness. The teardown of a FWSEC-only carve is not host-recoverable on this
+ fused part, so the GPU is left in the documented fail-safe (protected
+ region up, distribution driver deliberately not rebound) and is being
+ restored by an approved reboot; the next stage is a single-cycle real boot
+ (secure verification -> bootloader -> RISC-V start -> resource-manager
+ initialization) so the normal boot lifecycle makes teardown valid.
- **The full CUDA driver-API smoke test passes with correct data**: the client
completes `cuCtxCreate -> cuMemAlloc -> cuMemcpyHtoD -> cuMemcpyDtoH ->
cuMemFree -> cuCtxDestroy` and prints `ALL OK`, with the 64-byte payload
