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
Readouts: "sig", "logsig_expanded", "logsig_words", "logsig_brackets". See the repository README for guarantees, benchmarks and limitations.
