## Knowledge Gaps
- **545 isolated node(s):** `bookmarkmanager/backend`, `ctxKey`, `loginView`, `ctxKey`, `test` (+540 more)
  These have ≤1 connection - possible missing edges or undocumented components.
- **215 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 `New()` connect `Series Acquisition Tests` to `Bookmarks API Tests`, `Cover & Acquire Internals`, `Session Middleware`, `Store Tests`, `Web UI Handlers`?**
  _High betweenness centrality (0.041) - this node is a cross-community bridge._
- **Why does `Open()` connect `Store Tests` to `Cover Fetch Test Helpers`, `Series Acquisition Tests`, `Bookmarks API Tests`, `PG Test Infrastructure`?**
  _High betweenness centrality (0.035) - this node is a cross-community bridge._
- **Why does `newRouter()` connect `Bookmarks API Tests` to `Cover Fetch Test Helpers`, `Bookmarks API Handler`, `Series Acquisition Tests`?**
  _High betweenness centrality (0.022) - this node is a cross-community bridge._
- **Are the 47 inferred relationships involving `testConfig()` (e.g. with `TestListRendersAcquiredCover()` and `TestPublicCoverNeverEchoesNonImage()`) actually correct?**
  _`testConfig()` has 47 INFERRED edges - model-reasoned connections that need verification._
- **Are the 8 inferred relationships involving `newWebTestServer()` (e.g. with `TestListRendersAcquiredCover()` and `TestPublicCoverRejectsUnknownAddress()`) actually correct?**
  _`newWebTestServer()` has 8 INFERRED edges - model-reasoned connections that need verification._
- **Are the 6 inferred relationships involving `newTestStore()` (e.g. with `TestCreateAndGetSession()` and `TestDeleteSessionIsPerReader()`) actually correct?**
  _`newTestStore()` has 6 INFERRED edges - model-reasoned connections that need verification._
- **What connects `bookmarkmanager/backend`, `ctxKey`, `loginView` to the rest of the system?**
  _589 weakly-connected nodes found - possible documentation gaps or missing edges._
