spec(ml-alpha): GPU/CPU contract, CUDA Graphs, cold-start, disconnect handling
Critical-review pass on the CfC+PPO design adds:
- Public API: mapped-pinned ingress slots, single DtoH per decision
- Section 5.5: CUDA Graph capture topology (perception / policy / training),
kernel inventory, cuBLAS Lt epilogue fusion, persistent ring layouts,
determinism mode, build-time cubin compilation, perf budget
- Section 5.6: Databento/IBKR disconnect + failure response, never-do list
- Section 6 cold-start: 4-state bootstrap, Phase B walk-forward stats as
pre-deployment kill-switch baseline, always-live ISV controllers
