# R04 — CATEGORY CONNECTIVITY MATRIX

**Source:** `data/SKILLS_GRAPH.json` (R-02F, 2026-06-22)  
**Mutation:** NONE

---

## Matrix Status

**RESULT: ALL VALUES = 0**

The category connectivity matrix cannot contain any non-zero value because the graph has 0 edges.

## Verified Edge Count Matrix (8 enumerated categories)

| | 01-perception | 02-reasoning | 03-memory | 04-action | 05-code | 11-web | 12-data | 13-creative |
|---|---|---|---|---|---|---|---|---|
| **01-perception** | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
| **02-reasoning** | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
| **03-memory** | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
| **04-action** | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
| **05-code** | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
| **11-web** | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |

| **13-creative** | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |

## Category Statistics

| Metric | Value |
|---|---|
| Most connected category | UNKNOWN — no edges |
| Least connected category | ALL EQUAL (0 edges each) |
| Disconnected categories | ALL 8 enumerated categories |
| Category bridge nodes | NONE — no edges |

## 9 Pending Categories

Categories 06, 07, 08, 09, 10, 14, 15, 16, 17 are not yet enumerated.  
They cannot appear in any matrix until R-02G completes enumeration.

## Expected High-Connectivity Category Pairs (post-edge extraction)

Based on skill taxonomy, these category pairs are expected to generate the most cross-category edges once R-05 runs:

| Pair | Expected reason |
|---|---|
| 01-perception ↔ 12-data | Perception feeds data processing |
| 02-reasoning ↔ 03-memory | Reasoning requires memory retrieval |
| 04-action ↔ 11-web | Web actions are action-execution |
| 05-code ↔ 12-data | Code manipulates data |
| 02-reasoning ↔ 04-action | ReAct pattern: reason then act |

**All above are predictions. Matrix must be recomputed after edges are added.**
