import numpy as np
from sigring import WindowSig

K = 1024                                   # scale: real increments * K -> integers
inc = np.random.default_rng(0).integers(-100, 101, (5000, 2)).astype(np.int64)
ws = WindowSig(d=2, n=4, window=64, scale=float(K), bits=64)   # bits=128 for headroom
sigs = ws.push_batch(inc, "sig", 1)        # one signature row per tick
print(sigs.shape, ws.guard_ok())           # guard_ok(): rigorous overflow certificate
