Where do you answer"is the agent allowed to do this?"–one place,orevery adapter? A Rust-based unified agent substrate called WARDEN is being developed as a scaffold that composes best-in-class subsystems from 64+ repositories. It uses a hub-and-spokes architecture with a single chokepoint for containment, and currently has five anchor stubs with real traits and types. The project aims to avoid rewriting 200 repos by attaching governance, memory, egress, and orchestration at one chokepoint. A Rust-purist unified agent substrate — a SCAFFOLD shape, not implementation . It composes the best-at pattern per subsystem from the june/29 teardown of 64+ repos governance ← omnigent/coven, memory ← resonant-lattice, egress/ANN/gateway/sandbox ← coder org, orchestration ← windmill, spend ← the hackathon "clamp-the-model" pattern . It does not rewrite 200 repos — it finds the one chokepoint and attaches containment once. Hub & spokes: warden-daemon = the hub the one spawn chokepoint ; every subsystem = a spoke under spokes/ . The shape / visual map: ARCHITECTURE.md /YogiSotho/warden/blob/main/ARCHITECTURE.md The manifest = table of contents: Cargo.toml /YogiSotho/warden/blob/main/Cargo.toml Materialized now ✓ stub : warden-core , warden-daemon ★ the chokepoint , warden-policy , warden-egress , warden-memory — each has real traits/types + todo bodies + // PORT FROM: cites. Expansion roster identity, ledger, sandbox, runtime, harness, gateway, ann, orchestrator, spend, acp, cli — specified in the Cargo.toml comments + ARCHITECTURE table. · roster : Northstar: everything Rust. Go/TS winners are translated in crate-by-crate; the port-from file:line sits in each stub's module doc comment, so translation is a lookup, not a redesign. cargo build builds the 5 anchor stubs todo bodies compile to expand: cargo new spokes/warden-
