Starlight Vault — Continuous Learning v1

Starlight Vault — Continuous Learning v1

"Every session leaves a Starlight Fragment. Enough fragments form a constellation."

The Starlight Vault is Arcanea's continuous learning system. It observes your creative patterns, captures them as Starlight Fragments (atomic learned behaviors), and evolves them into constellations of reusable knowledge.

Concepts

Arcanean Term	Technical Term	Description
Starlight Fragment	Instinct	One trigger → one action, confidence-weighted
Constellation	Evolved Skill	Cluster of related fragments that form a skill
Starlight Vault	Instinct Store	Per-project + global storage
Fragment Gathering	Observation	Captured tool use events
Crystallization	Promotion	Fragment proven across 2+ projects → global

Fragment Structure

Fragments are stored as YAML files with frontmatter:

---
id: prefer-server-components
trigger: "when creating new React components"
confidence: 0.7
domain: "code-style"
source: "session-observation"
scope: project
project_id: "arcanea-web"
project_name: "Arcanea"
---

# Prefer Server Components

## Action
Use Server Components by default. Only add 'use client' when state or effects are needed.

## Evidence
- Observed 8 instances of server-first pattern
- User corrected client component to server on 2026-03-10

Confidence Scoring

Observations	Confidence	Level
1-2	0.3	Tentative (dim fragment)
3-5	0.5	Moderate (glowing fragment)
6-10	0.7	Strong (bright fragment)
11+	0.85	Very strong (radiant fragment)

Adjustments:

• +0.05 per confirming observation
• -0.1 per contradicting observation
• -0.02 per week without observation (fade)

    commands/                   # Evolved into commands

Commands

• /instinct-status — Show all fragments with confidence levels
• /instinct-export — Export fragments for sharing
• /instinct-import — Import fragments from another vault

Integration

The Starlight Vault connects to Arcanea's SIS memory layer. Fragments with confidence >= 0.8 are automatically surfaced in relevant sessions.
