## Knowledge Gaps
- **58 isolated node(s):** `yt-channel-scraper`, `Qué es esto`, `Comandos`, `Orientación antes de leer código`, `Tres superficies, un solo pipeline` (+53 more)
  These have ≤1 connection - possible missing edges or undocumented components.
- **3 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 `Store` connect `Store & Export Layer` to `Transcript Extraction & Parsing`, `Config & Discovery Pipeline`, `CLI Command Layer`, `Segments Search & Backfill`, `Content Analysis`, `pipeline.py`?**
  _High betweenness centrality (0.151) - this node is a cross-community bridge._
- **Why does `VideoRef` connect `Content Analysis` to `Config & Discovery Pipeline`, `Store & Export Layer`, `CLI Command Layer`, `Store Platform Tests`, `pipeline.py`?**
  _High betweenness centrality (0.048) - this node is a cross-community bridge._
- **Why does `Segment` connect `pipeline.py` to `CLI Command Layer`, `test_extract.py`, `Segments Search & Backfill`?**
  _High betweenness centrality (0.032) - this node is a cross-community bridge._
- **Are the 13 inferred relationships involving `Store` (e.g. with `ParsedMarkdown` and `store()`) actually correct?**
  _`Store` has 13 INFERRED edges - model-reasoned connections that need verification._
- **Are the 31 inferred relationships involving `VideoRef` (e.g. with `IncrementalDiscovery` and `store()`) actually correct?**
  _`VideoRef` has 31 INFERRED edges - model-reasoned connections that need verification._
- **Are the 11 inferred relationships involving `Config` (e.g. with `test_config_languages_defaults_to_dict()` and `test_config_prefer_manual_defaults_true()`) actually correct?**
  _`Config` has 11 INFERRED edges - model-reasoned connections that need verification._
- **What connects `yt-channel-scraper`, `Qué es esto`, `Comandos` to the rest of the system?**
  _58 weakly-connected nodes found - possible documentation gaps or missing edges._
