Copyright (c) 2026 LRNSdigital (souzalrns). Licensed under the MIT License (see LICENSE).

tokenwright has no third-party runtime dependencies. Prices are a plain Python mapping and
the engine is the Python standard library only (json, pathlib). Load prices from JSON, YAML
or a database yourself and pass the mapping in.

Extracted from the governed runner at github.com/souzalrns/network-agents-setup
(runner/plan_runner/cost.py). The runner keeps its YAML price config and the worker wiring;
this package is the standalone, dependency-free cost-ledger and budget-cap core.
