# INITIATIVE-001C — Graph Quality, Integrity & Recommendation Readiness Audit

**Date:** 2026-06-22  
**Mission:** INITIATIVE-001C  
**Evidence source:** Direct read of `data/SKILLS_GRAPH.json` (SHA: `639b9cbb4be5ec78f12ae2a7b733f9a5da3f9e89`), `schema/skill.schema.json`, `schema/edge.schema.json`, `tools/recommend.py`

## PRE-FLIGHT VERIFICATION

| Check | Expected | Actual | Result |
|---|---|---|---|
| `schema_version` | `3.0` | `3.0` | ✅ PASS |
| Node count | 367 | 367 | ✅ PASS |
| Edge count | 773 | 773 | ✅ PASS |
| `meta.node_count` matches array length | — | 367 = 367 | ✅ PASS |
| `meta.edge_count` matches array length | — | 773 = 773 | ✅ PASS |
| Graph is not placeholder string | — | Confirmed | ✅ PASS |

No STATE_DIVERGENCE_REPORT required.

## PHASE 1 — Schema Validation

### Node Schema (`skill.schema.json`)

Required fields: `id`, `title`, `category`, `level`, `stability`, `version`

| Check | Result | Count |
|---|---|---|
| Nodes missing required fields | ✅ PASS | 0 |
| Invalid `level` value | ✅ PASS | 0 |
| Invalid `stability` value | ⚠️ 1 node | `02-reasoning/reasoning-under-uncertainty` uses `"evolving"` — not in schema enum (`stable`, `experimental`, `deprecated`) |
| Invalid `layer` value | ✅ PASS | 0 |
| `source_file` missing | ✅ PASS | 0 |
| `quality_score` = null | ⚠️ ALL | 367/367 (100%) — not yet scored |
| `tags` = [] (empty) | ⚠️ ALL | 367/367 (100%) — `extract_edges.py` has not populated tags |
| `related_skills` = [] (empty) | ⚠️ ALL | 367/367 (100%) — sidecar metadata not extracted |

### Edge Schema (`edge.schema.json`)

Required fields: `source`, `target`, `type`, `evidence`, `source_file`

| Check | Result | Count |
|---|---|---|
| Edges missing required fields | ✅ PASS | 0 |
| Invalid `type` value | ✅ PASS | 0 |
| Dangling source (source not in node_ids) | ✅ PASS | 0 |
| Dangling target (target not in node_ids) | ❌ FAIL | 9 edges — targets reference non-existent node IDs |
| Self-loops | ✅ PASS | 0 |
| Duplicate edges | ✅ PASS | 0 |
| Missing `confidence` | ✅ PASS | 0 — all 773 have `"high"` |
| Empty `evidence` | ✅ PASS | 0 |

#### Dangling Target Edges (9)

| Source | Target (MISSING from graph) |
|---|---|
| `02-reasoning/goal-decomposition` | `09-agentic-patterns/memory-augmented-agent` |
| `02-reasoning/meta-prompting` | `02-reasoning/prompt-engineering` |
| `02-reasoning/meta-prompting` | `09-agentic-patterns/react-pattern` |
| `02-reasoning/meta-prompting` | `09-agentic-patterns/reflection-pattern` |
| `02-reasoning/planning-decomposition` | `09-agentic-patterns/react-pattern` |
| `02-reasoning/reasoning-under-uncertainty` | `09-agentic-patterns/reflection-pattern` |
| `02-reasoning/reasoning-under-uncertainty` | `03-memory/rag-retrieval` |
| `02-reasoning/step-back-prompting` | `02-reasoning/prompt-engineering` |
| `02-reasoning/step-back-prompting` | `09-agentic-patterns/rag-pattern` |

All 9 reference nodes that exist as source files but use different ID slugs than those registered in the graph.

## PHASE 2 — Graph Structure Audit

### Category Distribution

| Category | Nodes |
|---|---|
| 01-perception | 36 |
| 02-reasoning | 45 |
| 03-memory | 19 |
| 04-action-execution | 21 |
| 05-code | 28 |
| 06-communication | 15 |
| 07-tool-use | 33 |
| 08-multimodal | 14 |
| 09-agentic-patterns | 23 |
| 10-computer-use | 20 |
| 11-web | 17 |
| 12-data | 18 |
| 13-creative | 14 |
| 14-security | 13 |
| 15-orchestration | 22 |
| 16-domain-specific | 28 |
| 17-infrastructure | 1 |

`17-infrastructure` has only 1 node and is 100% orphaned. Candidate for consolidation.

### Node Level Distribution

| Level | Count |
|---|---|
| basic | 55 |
| intermediate | 188 |
| advanced | 124 |

### Stability Distribution

| Stability | Count |
|---|---|
| stable | 350 |
| experimental | 16 |
| evolving (invalid) | 1 |

### Layer Distribution

| Layer | Count |
|---|---|
| perception | 36 |
| reasoning | 64 |
| execution | 51 |
| systems | 216 |

### Edge Type Distribution

| Type | Count |
|---|---|
| RELATED_TO | 773 |
| REQUIRES | **0** |
| SUPPORTS | 0 |
| SUBSKILL_OF | 0 |
| ALTERNATIVE_TO | 0 |

**CRITICAL: All 773 edges are type `RELATED_TO`. No `REQUIRES` edges exist.**

### Edge Confidence Distribution

| Confidence | Count |
|---|---|
| high | 773 |
| medium | 0 |
| low | 0 |

All edges rated `high` confidence. This is statistically implausible for 773 extracted edges and indicates a confidence assignment issue in the extraction pipeline.

## PHASE 3 — Orphan Audit

**Orphan nodes (no edges): 54 / 367 (14.7%)**

| Category | Orphaned | Total | % |
|---|---|---|---|
| 01-perception | 15 | 36 | 42% |
| 02-reasoning | 17 | 45 | 38% |
| 03-memory | 2 | 19 | 11% |
| 04-action-execution | 1 | 21 | 5% |
| 05-code | 1 | 28 | 4% |
| 07-tool-use | 3 | 33 | 9% |
| 09-agentic-patterns | 4 | 23 | 17% |
| 11-web | 1 | 17 | 6% |
| 14-security | 2 | 13 | 15% |
| 15-orchestration | 6 | 22 | 27% |
| 16-domain-specific | 1 | 28 | 4% |
| 17-infrastructure | 1 | 1 | 100% |

---

## PHASE 4 — Degree Analysis

| Metric | Value |
|---|---|
| Sink nodes (out_degree = 0) | 88 |
| Source nodes (in_degree = 0) | 112 |
| Max in-degree | 13 (`05-code/code-generation`) |
| Max out-degree | 5 (`02-reasoning/planning-decomposition`) |

**Top hub nodes by in-degree:**
1. `05-code/code-generation` — 13
2. `03-memory/rag` — 12
3. `01-perception/image-understanding` — 11
4. `01-perception/document-parsing` — 11
5. `09-agentic-patterns/reflection` — 11

---

## PHASE 5 — Recommendation Readiness

| Capability | Status | Blocker |
|---|---|---|
| Goal matching (title/id keyword) | ✅ FUNCTIONAL | None — id + title populated on all 367 nodes |
| Tag-based matching | ❌ BLOCKED | tags=[] on all 367 nodes |
| Dependency resolution (backward BFS on REQUIRES) | ❌ BLOCKED | 0 REQUIRES edges |
| Learning path generation (topological sort) | ❌ BLOCKED | No REQUIRES edges |
| Dependency analysis | ❌ BLOCKED | No REQUIRES edges |
| Architecture generation | ⚠️ DEGRADED | RELATED_TO enables co-occurrence only |
| Recommendations (basic) | ⚠️ PARTIAL | Keyword match works; path ordering broken |

---

## PHASE 6 — Blockers

| ID | Finding | Severity |
|---|---|---|
| B-001 | 0 REQUIRES edges — all 773 are RELATED_TO | **CRITICAL** |
| B-002 | tags=[] on all 367 nodes | **HIGH** |
| B-003 | related_skills=[] on all 367 nodes | **HIGH** |
| B-004 | quality_score=null on all 367 nodes | **MEDIUM** |
| B-005 | 9 dangling target edges | **MEDIUM** |
| W-001 | 1 node with invalid stability `"evolving"` | LOW |
| W-002 | 54 orphan nodes (14.7%) | MEDIUM |
| W-003 | All 773 edges `confidence: "high"` — implausible | LOW |
| W-004 | `17-infrastructure` has 1 node, 100% orphaned | LOW |
