wco.policy.json — pin adapter behaviour · WCO.ai

The lock file format that pins which adapters may run, which losses are permitted, and which tokenizer is authoritative, so an optimization decision is reproducible across environments and over time.

The interactive playground and tools require JavaScript because they run the optimization engine locally in your browser rather than sending your data to a server.
