The upstream bridge executables are unmodified. The templates are generated from their pinned images. Synapse's encrypted R2 storage plugin and its build recipe in `synapse/` are additions by Xessenger, 2026-10-02, licensed under AGPL-3.0-only. The AGPL text is included here. There is no warranty for these open-source components.

Before activating this runtime for users, the deployment must provide a public source download containing the exact R2 plugin/build recipe, this notice/license and links to the exact upstream source versions. Private operational configuration, credentials and user data must never be included in that download. The local test environment does not publish repository content.
