# Third-party code

INBUXA is a fork of Stalwart. Stalwart is original work by Stalwart Labs LLC,
not a fork of anything, but a few of its files carry code, adapted or ported,
from other projects under permissive licenses. Those parts stay under their own
licenses, not the AGPL, and their notices are reproduced here as the licenses
require. Where a project offers MIT or Apache-2.0, INBUXA takes it under MIT.

`tools/fork/strip.py` lists every such file on each upstream import and names
any this page doesn't cover yet (docs/spec/SPEC.md §2.2). The fork's own code,
and Rust crates pulled in as dependencies, aren't listed here: dependencies
carry their own license files.

## Credited algorithms

These files implement published algorithms and credit their source. No code
is copied, so there's no notice to carry. They're listed so the strip report
doesn't flag them as new.
