Authority Domains

Reference table for what each Nimi authority domain owns and does not own.

Domains

Domain	Owns	Does not own
Platform	World model, six protocol primitives, authority rules, app slice admission, AI last-mile action boundary, AI agent security interface	World truth; AI execution; app integration; UI rendering
Runtime	AI execution (text/image/video/audio/embedding/STT/TTS), workflows, streaming, multimodal artifacts, local capability routing, GPU arbitration, model lifecycle, agent execution (Chat Track / Life Track / Runtime HookIntent scheduling), runtime-local memory, knowledge banks, app-to-app messaging, delegated capability gateway, output firewall, local audit	World truth; SDK projection; UI; Cognition authority; Realm authority
SDK	App-facing access surface, surface contracts, transport, error projection, import boundaries	Runtime / Realm / Cognition / Desktop internals; new platform truth; runtime execution
Desktop	Native first-party shell, native bridging, window/menu behavior, local integration boundaries, first-party user workflows, External Agent Access placement	Runtime execution; SDK contract definition; Realm truth; Avatar embodiment authority; External Agent action authority
Web	Constrained browser projection of admitted Desktop surfaces	Native runtime bootstrap; native window; sensitive token persistence beyond browser-safe limits
Realm	World truth, world state, world history, chat, social, economy, asset, transit, binding, resource, bundle	Runtime execution; SDK projection; Desktop UI decisions; Cognition memory authority
Avatar	Embodied agent presentation, embodiment projection, carrier visual acceptance, backend branches (Live2D / VRM / generated motion), agent script, avatar event surface	Agent identity (Runtime); agent memory (Cognition); world truth (Realm); generation (Runtime)
Cognition	Standalone memory, knowledge, prompt serving, references, completion gates, skill service, runtime bridge contract, runtime upgrade contract	Runtime execution; Realm truth; Avatar embodiment; Desktop UI
Nimi Coding	Topic / wave / packet / preflight / audit / closeout methodology, four-closure framework, role-separation policy, authority-convergence policy, forbidden-shortcuts catalog, host-agnostic boundary, declared skills	Runtime execution; product code; AI host implementation; provider invocation

Cross-Domain Relationships

Edge	Direction	Carries
`desktop → nimi-sdk`	unidirectional	Unified developer surface
`desktop → nimi-runtime`	unidirectional	gRPC runtime access
`nimi-apps → Realm public API boundary`	unidirectional	REST + WS realm access
`nimi-runtime ↔ nimi-cognition`	bidirectional bridge	Runtime consumes cognition; cognition retains authority
`nimi-runtime ↔ Realm public API boundary`	sibling	Neither depends on the other; SDK bridges them

Boundary Rules

Boundary	Rule
Apps must use SDK	Apps cannot import private Runtime / Realm internals; SDK is the boundary
SDK does not redefine	SDK projects upstream contracts; does not invent new product truth
Runtime cannot absorb Cognition	Bridge contract is consumption; authority remains with Cognition
Cognition cannot redefine Realm	Memory and knowledge are not world truth
Web cannot imply Desktop-native	Web adapter disables capabilities the browser cannot honor
Avatar cannot redefine agent	Presentation is downstream of identity

Authorization Presets

Preset	Read	Write	Delegate
`readOnly`	yes	no	no
`full`	yes	yes	no
`delegate`	yes	yes	one level

App Modes

Mode	Read	Write	Active count per world
`render-app`	yes	no	many
`extension-app`	yes	yes	at most one active
