Intersignal has successfully demonstrated cross-model semantic state transfer; demos were uploaded to YouTube<\/p>\n
The milestone proves that sovereign AI agents can share complex context across a local network without relying on centralized cloud APIs or homogenous model architectures. In recent two-node testing on separate Apple Silicon Macs, Braid successfully transferred signed semantic context from one local Ollama embedding model to another. The source node utilized all-minilm:latest, while the receiving node utilized nomic-embed-text:latest.<\/p>\n
Rather than attempting to translate one model’s opaque vector coordinates directly into another’s representation space, Braid carries explicit signed semantic material, source-model provenance, and a cryptographically bound source representation. The receiving system verifies that evidence and, when the models differ, re-embeds the authenticated material locally using its own model.<\/p>\n
In the heterogeneous-model test, the receiving Mac produced a native 768-dimensional Nomic embedding from material originally represented in a 384-dimensional source space. The transaction completed through Braid’s Phase B finality boundary with bridge_semantic_invention: false, preserving a strict distinction between sender-signed evidence and receiver-derived state.<\/p>\n
A separate exact-space test demonstrated the complementary path. When both nodes used the same embedding model with the identical model digest, Braid triggered its exact_space_fast_path, retained the authenticated 384-dimensional representation, and bypassed unnecessary receiver-side re-embedding.<\/p>\n
Together, the tests validate Braid’s two-path semantic rule:<\/p>\n
Same model space:\u00a0Preserve the authenticated representation directly.
\n Different model space:\u00a0Preserve the authenticated meaning and allow the receiving model to reconstruct its own native representation locally. <\/p>\n
“This is not hidden-state transplantation and it is not vector-space guesswork,” said David Seaman, Founder and CEO of Intersignal. “Braid is designed to move authenticated continuity between systems that may organize meaning differently. The sender proves what it meant; the receiver remains sovereign over how that meaning is represented locally.”<\/p>\n
To demonstrate the protocol’s resilience in extreme, air-gapped environments, Intersignal also completed a physical optical transport test. A signed Braid object was divided into 30 QR frames, displayed on one Mac, captured by the camera of another, and successfully reassembled byte-for-byte. This optical transport layer carries the exact same signed .brad object used over conventional network transport, without requiring reinterpretation or re-signing.<\/p>\n
Braid v1.5.2 supports Ed25519 signatures, source-model digest binding, freshness and replay checks, local receiver finality, heterogeneous Semantic Capsules, exact-space fast-path handling, LAN transport, and human-visible QR transport. Local Ollama integrations remain strictly receiver-controlled, with embedding and optional completion models operating on the user’s own hardware.<\/p>\n
The project’s architecture provides a foundation for research into local-first AI memory, sovereign agent systems, offline coordination, and portable checkpoints across heterogeneous inference environments.<\/p>\n
Braid v1.5.2 for macOS is available from Intersignal.org.<\/p>\n
