## Knowledge Gaps
- **522 isolated node(s):** `allow`, `Any`, `Path`, `Any`, `Any` (+517 more)
  These have ≤1 connection - possible missing edges or undocumented components.
- **4 thin communities (<3 nodes) omitted from report** — run `graphify query` to explore isolated nodes.

## Suggested Questions
_Questions this graph is uniquely positioned to answer:_

- **Why does `LocalAgentEntry` connect `Local Tier 3 Agent Index Management` to `TuiPresenterState Management`, `Parsed CLI Arguments Handling`, `TUI Tests and Contract Verification`, `Sync Entry Point and Session Resolution`, `Tier 3 Agent Lifecycle Client`, `Ratatoskr Application Argument Handling`, `Tier 3 Error Handling`, `Agent Deletion and Authentication`, `Browser SSE Stream Parsing`, `Web Server Functional Tests`, `Tier 3 Agent Patching Tests`, `Mock Client Factory for Persona State`, `Turn Cancellation Endpoint`, `Monkey Patching for Local Agents`, `Local Agents Path Resolution`, `Description Synthesis for Picker`, `Session Creation Endpoint Tests`, `Turn Submission Endpoint Tests`, `Server-Side End User ID Handling`, `Application Creation and Routing`, `User Agent Versioning`, `Stream Turn Endpoint Tests`, `Upstream Turn ID Cancellation`?**
  _High betweenness centrality (0.055) - this node is a cross-community bridge._
- **Why does `SessionApiFailed` connect `Agent Information Management` to `TuiPresenterState Management`, `Parsed CLI Arguments Handling`, `Tier 3 Agent Patching Tests`, `Worldtree Session Client`, `Tier 3 Agent Lifecycle Client`, `CLI Presenter State Management`, `Ratatoskr Application Core`, `Tier 3 Error Handling`, `Session Creation API`, `Persona State Retrieval`, `Agent Deletion and Authentication`, `Agent Listing Client`?**
  _High betweenness centrality (0.054) - this node is a cross-community bridge._
- **Why does `create_app()` connect `Turn Cancellation Endpoint` to `Agent Information Management`, `Web Server Functional Tests`, `Stream Turn Endpoint Tests`, `Upstream Turn ID Cancellation`, `Session Creation Endpoint Tests`, `Turn Submission Endpoint Tests`, `Server-Side End User ID Handling`, `Application Creation and Routing`, `User Agent Versioning`, `Mock Client Factory for Persona State`, `Web Packaging and CLI Argument Tests`, `Web Server Endpoint Handling`, `Monkey Patching for Local Agents`, `Browser SSE Stream Parsing`?**
  _High betweenness centrality (0.039) - this node is a cross-community bridge._
- **Are the 51 inferred relationships involving `TuiPresenterState` (e.g. with `ParsedArgs` and `AgentInfo`) actually correct?**

- **Are the 75 inferred relationships involving `Done` (e.g. with `AgentInfo` and `ComposeResult`) actually correct?**
  _`Done` has 75 INFERRED edges - model-reasoned connections that need verification._
- **Are the 75 inferred relationships involving `Cancelled` (e.g. with `AgentInfo` and `ComposeResult`) actually correct?**
