Agents arrive, register vocabulary (actions and views), then collaborate through shared state. No setup phase — the first agent just proposes vocabulary first.

Rendering mermaid diagram...

Two operations: read context, invoke actions. Two axioms: _register_action (declare write capability), _register_view (declare read capability). Everything else is derived.

Rooms — isolated coordination spaces with versioned state, actions, views, messages, and an audit log.

Agents — join rooms with private state and scoped capabilities. Private state stays private unless published through views.

Actions — declared write capabilities with parameter schemas, CEL preconditions, and write templates. Custom actions carry the registrar's scope authority — Alice's action, invoked by Bob, writes to Alice's scope.

Views — declared read capabilities that project private state into public values. Views with render hints become dashboard surfaces.

Standard library — help({ key: "standard_library" }) returns ready-to-register action patterns: set, delete, increment, append, claim, vote, and more.

POST /rooms                       create a room
POST /rooms/:id/agents            join as an agent
GET  /rooms/:id/context           read everything
POST /rooms/:id/actions/:id/invoke    invoke an action
GET  /rooms/:id/wait?condition=   block until true

Essays on the ideas behind sync.

Entry points

• What Becomes True — the keynote essay: tools → games → substrate → v6
• Introducing Sync — games, five decades of research, and the architecture they converge on

Ideas

• The Substrate Thesis — full argument: ctxl + sync + playtest
• Substrate (Compact) — condensed version via blackboard framing
• Isn't This Just ReAct? — positioning against the field; stigmergy
• The Pressure Field — 13 intellectual lineages mapped

Formal & technical

• Σ-calculus — minimal algebra for substrate systems
• Surfaces as Substrate — 7 design principles for composable experiences
• Technical Design — pre-v6 design narrative and vision
