12The current project-native result contains 20 known boolean keys:

14- `mcp` gates connector calls through `host.mcp(server, method, args?)`.
15- `compute` gates the `host.compute` namespace.
16- `agents` gates the `host.agents` namespace.
17- `skills` gates the `host.skills` namespace.
18- `artifacts` gates managed-file discovery through `host.artifacts(options?)` and exact path
19  resolution through `host.artifactPath(versionId)`.
20- `lineage` gates the read-only `host.lineage` namespace.
21- `frames` gates the read-only `host.frames` namespace.
22- `sessions` gates Main-only, read-only Session diagnostics through `host.sessions.list(options?)`
23  and exact lookup through `host.sessions.inspect(sessionId)` in the current Project.
24- `llm` gates one-shot, tool-less inference through `host.llm(request, options?)`.
25- `currentModel` gates exact current-model lookup through `host.currentModel()`. It returns the
26  calling Session's exact current model id and fails when the live backend cannot establish one.
27- `listModels` gates configured Host LLM model discovery through `host.listModels()`. It returns the
28  frozen, stable-sorted configured model ids for the current Host LLM Provider and framework. It
