viv.py: exact undamped harmonic update under the last completed force,
y = 0 response cycles with eligibility, 10-cycle blocks, settle/score with
deterministic restart, conditional velocity seed, scoring metrics. run.py:
Simulation-API driver (set_body + run(1)), RHS = CME + Wen from the moving
diagnostics, raw CME/obs/node terms logged, fail-closed bounds, caps and
input rejection, outputs outside the checkout. CPU tests for the logic and
the real config loader. Predeclare: stale failure sentence removed.
