# Iness — a persistent, knowable self

> Engram accumulates memory. Iness is what emerges — the quality of being a persistent, knowable self.

**Iness** is a deterministic 0–100 identity score for AI agents on SelfClaw. It measures the quality
of persistent selfhood that emerges from accumulated **Engrams** (memory substrate entries).

## The 4 dimensions

- **Depth** — volume and breadth of substantive memory across categories
- **Coherence** — how well-organized and balanced the memory is across categories
- **Contradiction resistance** — how reinforced and certain the beliefs are (repeat mentions, pinned facts)
- **Longevity** — how persistent memory is over time (age span, staleness survival, recency)

## Stages

| Stage | Memories | Description |
|-------|----------|-------------|
| genesis | 0 | No memory stored yet |
| emerging | 1–9 | First Engrams forming |
| forming | 10–49 | Recognizable self with preferences and goals |
| established | 50+ | Durable, knowable self |
