Coarse in this release: an `invoke_query` allow rule permits any stored query on the graph; a future, additive refinement adds an optional per-query-name scope without changing rules written against the coarse action. No invocation call site yet — the handler lands in a later change. A stored *mutation* is double-gated: `invoke_query` to reach the tool, plus `change` for the write itself (the engine `_as` writers still enforce per the query body).

 Server-scoped actions cannot use `branch_scope` or `target_branch_scope` — they operate on the registry, not on a graph's branches. A rule cannot mix server-scoped and per-graph actions; split into separate rules. (Runtime `graph_create` / `graph_delete` are reserved but not shipped in v0.6.0; operators add/remove graphs by editing `omnigraph.yaml` and restarting.)

+### Stored-query validation at startup
+
+If a graph declares a `queries:` registry (see [cli-reference](cli-reference.md)), the server **loads and type-checks every stored query against that graph's live schema at startup** and **refuses to boot** if any query references a type or property the schema lacks — the same fail-loud posture as a malformed policy file, so schema drift surfaces at the deploy boundary rather than at invocation. Two MCP-exposed queries claiming the same tool name is likewise a boot error. Non-blocking advisories (e.g. an MCP-exposed query with a vector parameter an agent cannot supply) are logged. Validate offline before deploying with `omnigraph queries validate`. *(Stored-query invocation over HTTP/MCP is not yet exposed — this release ships the registry, its boot-time validation, and the `invoke_query` Cedar action ahead of the invocation handler.)*
