0token is an independent, complementary tool for the Headroom token-compression
engine (https://github.com/headroomlabs-ai/headroom), which is licensed under
the Apache License, Version 2.0.

0token does not fork or redistribute Headroom's source code. It reads the public
output that a locally-running Headroom instance produces on the user's own
machine — the append-only savings_events.jsonl ledger, the proxy_savings.json
aggregate, and the loopback HTTP API — and renders it.

"Headroom" is the name of that upstream project and is used here only to describe
interoperability. Its use does not imply endorsement or sponsorship by the
Headroom project or its contributors.

The upstream Headroom NOTICE is preserved for reference at
docs/HEADROOM-NOTICE.txt.
