+# Retroactive Edge Creation for Cognitive Memory
+
+## Problem
+
+Memory graph had only 34 edges across 473 memories — very sparse, limiting graph traversal usefulness.
+
+## Solution
+
+Built `~/.claude/skills/cognitive-memory/scripts/edge-proposer.py` that analyzes all active/fading memories and proposes candidate edges.
+
+### Scoring Algorithm
+
+Three signals combined:
+- **Type heuristics** (40%): e.g., fix + problem → SOLVES relationship
+- **Tag Jaccard similarity** (30%): shared tags indicate related topics
+- **Content keyword overlap** (30%): common terms in body text
+
+### Results
+
+- First run on 473 memories produced 5,186 candidates
+- Manually reviewed top 80 candidates
+- Selected 20 high-quality edges across 8 project clusters:
+  - Gitea CI/CD: 3 edges
+  - Paper Dynasty: 3 edges
+  - Major Domo: 4 edges
+  - Database patterns: 2 edges
+  - Cognitive memory: 1 edge
+  - Proxmox: 1 edge
+  - Vagabond RPG: 3 edges
+  - OpenSCAD: 3 edges
+- Grew edge count from 34 to 54
+
+### Noise to Skip
+
+Session-log FOLLOWS pairs (auto-generated episode entries) were identified as low-value noise and excluded from selection.
