This is the single source of truth for the public-facing Web4 ecosystem. If a doc elsewhere describes one of these repos differently, prefer this file.
The open substrate and authoritative Hub source. Canonical Web4 specifications, published core packages, Hub source, trust primitives, simulations, attestation work and whitepapers. Identity, authority, contextual trust, witnessed action and machine-readable society law live here. Durable Hub runtime/federation/mesh functionality, generic tests, fixtures and portability support are authoritative here as well; fleet-private repositories may hold evidence and operational context but not a competing implementation.
License: AGPL-3.0-or-later; see each package directory and PATENTS.md for exact terms.
The local governance runtime. Gives humans and AI agents from multiple vendors one local law, scoped authority, an encrypted vault, witnessed action history, escalation and trust derived from the record.
Current assurance: A1 - cooperative and tamper-evident, useful for governance and attribution, not containment against a determined same-UID adversary.
Use when: governing agents at the person/machine boundary or evaluating the open reference implementation of Web4 action law.
The Web4 society/community runtime, standalone mirror. A read-only mirror of this monorepo's hub/ directory plus the core crates it builds on. Single-binary Rust daemon: membership, eight base roles, signed machine-readable law, sealed member channels, MCP + REST surfaces and an append-only witnessed ledger. It is not an independent authority: changes originate in dp-web4/web4 and flow outward.
Use when: you want to run or inspect a Web4 society without cloning the full standard.
Persistent cognition and embodiment research. Extends Web4 identity and governance into local agents with memory, context, sensors, learning and eventually physical effectors. The public repo contains the kernel architecture and frozen research milestones; active capability work also continues in private research repos.
Use when: studying how persistent agents can learn and act under the same identity, authority and accountability substrate.
Historical ARC note: SAGE/ARC work produced a published spring-2026 94.85% scorecard with Claude Opus 4.6. It is preserved as a research milestone, not a current competition-leadership claim. The run used a frontier model and affordances outside strict competition play; current competition-legal local-model work is well behind the leaders. See docs/proof/ARC-AGI-3.md for the historical record.
Interactive lifecycle and trust-evolution explainer. A browsable demo of how agents earn trust over time - witnessing, accumulation, decay. Live deployment: https://4-life-ivory.vercel.app/
Use when: introducing Web4 trust evolution to a non-technical audience, or sanity-checking that the spec doesn't assume too much.

Public-facing governance site and demo material. The live site hosts the long-form framing around AI accountability and governance. The site's source repo is private; the deployed site is the public artifact.
Use when: needing audience-facing framing rather than the technical spec.
Blue-sky theoretical exploration. Synchronism influenced Web4's MRH framing and some of the lab's coherence vocabulary, but it is not an engineering dependency and its physics claims remain conjectural.
Use when: tracing conceptual origins or exploring the broader theoretical program.
Earlier distributed-ledger exploration around ATP/LCT state. A Cosmos SDK implementation from the broader research lineage.
The former dp-web4/HRM edge-AI research lineage became SAGE. The old HRM URL redirects there; use the SAGE entry above.
Metalinxx's proprietary enterprise assurance tier. Hardware-bound identity, stronger fail-closed enforcement and audit-ready evidence packaging for deployments where the open A1 governance profile is not sufficient.
Built on the open Web4 substrate. Hardbound is the enterprise assurance layer; Web4 is the interoperable foundation.
