The WebAssembly engine, parameter table and browser adapter originate from jamesdsp-web revision 77be0b2e825a20ba98feff33d16dd0a43232ef3b. Source is available in that repository and the underlying JamesDSPManager source is referenced by its upstream/ tree. The runtime files remain in the lazy feature:jamesdsp asset group; license and provenance documents are not runtime assets.

jamesdsp-node.js and worklet.js carry the integration changes described in VERSION.txt. The generated C engine and params.js are unchanged from the pinned revision. The Node wrapper intentionally rejects text-effect parameters and does not serialize text, preventing Liveprog/DDC/arbitrary text payloads from entering the v1 surface.

The upstream upstream/Main/LICENSE text says GPL-2.0 while the port repository ships a GPL-3.0-or-later license. Both texts are retained as supplied. Confirm the upstream provenance and redistribution position before a public release; this note is not a legal conclusion.
