## Isolated Node Analysis

**112 nodes have no verified edges.**  
Cause: skill files not yet read in this session, OR files exist but have no `Related Skills` section.  
These nodes are NOT orphans — they are registered in the node registry and have skill files.  
They require a follow-up R-04 pass to extract their edges.

| Category | Isolated Count | Total in Category |
|---|---|---|
| 02-reasoning | 13 | 40 |
| 03-memory | 15 | 16 |
| 05-code | 25 | 26 |
| 07-tool-use | 30 | 31 |
| 09-agentic-patterns | 12 | 19 |
| 12-data | 17 | 18 |

## Coverage Status

R-03 read skill files from **02-reasoning only** (the category with the richest Related Skills sections).  
Categories 03-memory, 05-code, 07-tool-use, 09-agentic-patterns, and 12-data have nodes registered  
but their individual skill files were not read in this session.  
**R-04 should prioritize reading those files to close the isolated node gap.**
