Chronos: Innovation Algebra & Trust SDK

A minimal, composable Python SDK for modeling change events, trust graphs, and innovation landscapes. Includes algebraic change sets, trust propagation, Riemannian geometry helpers, and a master equation integrator.

Features

• Change Algebra: Immutable, timestamped change events and sets with union/intersection/difference, composition, inversion, and state evolution.
• Trust Graphs: Weighted directed trust networks with path aggregation and logistic update law (requires networkx).
• Manifold Geometry: Minimal Riemannian metric/geodesic/curvature helpers (requires numpy).
• Navigator: Lightweight forward-Euler integrator for arbitrary vector fields.

Installation

With UV:

uv pip install chronos

Or with pip:

pip install chronos

Usage

Change Algebra

from chronos import ChangeEvent, ChangeSet, change_set

# Create events
c1 = ChangeEvent(timestamp=1.0, state_before=0, state_after=1)
c2 = ChangeEvent(timestamp=2.0, state_before=1, state_after=2)

# Create a set
cs = ChangeSet([c1, c2])

# Algebraic ops
cs2 = cs.inverse()
cs3 = cs.union(cs2)

Trust Graphs

from chronos import TrustGraph
T = TrustGraph()
T.set_trust('alice', 'bob', 0.8)
T.update_trust('alice', 'bob', delta=0.1)
trust = T.get_trust('alice', 'bob')

Manifold Geometry

from chronos import Metric, geodesic, curvature
import numpy as np
metric = Metric(lambda x: np.eye(len(x)))
path = geodesic(metric, np.array([0,0]), np.array([1,1]))
curv = curvature(metric, np.array([0,0]))

Navigator

from chronos import Navigator
import numpy as np
nav = Navigator(lambda x: -x)
traj = nav.integrate(np.array([1.0, 0.0]), steps=10)

Requirements

• Python 3.9+
• networkx (for trust graphs)
• numpy (for manifold & navigator)
