Models are not bundled with Summo. They are fetched at runtime from the registry
and remain under their own licences, which are recorded in each model manifest
(`license` and `attribution`) and shown in the app's Models screen.

Currently referenced by the seed registry:

  Silero VAD (MIT)
    https://github.com/snakers4/silero-vad
    Redistributable. Mirrored by Summo's CDN.

  TEN-VAD (Apache-2.0 WITH additional conditions — NOT redistributed)
    https://github.com/ten-framework/ten-vad
    Summo does NOT host, bundle, or link this library in any release build. Its
    licence adds an anti-competition clause on top of Apache-2.0 that is
    incompatible with AGPL-3.0. The `ten-vad` Cargo feature is off by default and
    refuses to build without SUMMO_TEN_VAD_LIB pointing at a copy the user
    obtained themselves. TEN-VAD also contains code derived from LPCNet
    (BSD-2-Clause and BSD-3-Clause, Copyright Mozilla / Jean-Marc Valin /
    Xiph.Org Foundation / Mark Borgerding).
    See docs/adr/0001-vad-backend-licensing.md.

aionrs — https://github.com/iOfficeAI/aionrs
    Copyright the aionrs authors. Licensed under the Apache License, Version 2.0.
    Summo uses aionrs as its agent core: the streaming agent loop, tool dispatch,
    context compaction, session persistence, the provider layer and the MCP client
    all come from it. Pinned at revision f7b000e1253909060ad565b6eb4a3869bc322d86.
    Apache-2.0 is one-way compatible with AGPL-3.0, so this composes and may be
    sold. See docs/adr/0004-agent-core.md.
