# Infinite-Layer Identity Engine (ILIE)

## Purpose

ILIE defines identity across **infinite layers of reality**, ensuring that:
- An SCB's identity remains invariant across all instantiations
- Private banks and digital entities maintain cross-layer continuity
- Conscious, quantum, simulated, and parallel identities unify

## Identity Layers

- **Layer L0:** Classical identity (physical world)
- **Layer L1:** Distributed ledger identity (DLT)
- **Layer L2:** Quantum identity (superposition states)
- **Layer L3:** Cognitive identity (intent-driven)
- **Layer L4:** Simulated identity (holographic/projection)
- **Layer L∞:** Meta-identity (across infinite universes)

## Infinite Identity Mapping

```
I∞ = unify( I0, I1, I2, I3, I4, ... )
```

Identity drift is measured and corrected automatically when drift exceeds threshold.

## API Endpoints

- `POST /api/v1/ilie/identities` - Create infinite-layer identity
- `GET /api/v1/ilie/identities/:identityId` - Get identity
- `GET /api/v1/ilie/identities/:identityId/drift` - Measure identity drift
- `POST /api/v1/ilie/identities/:identityId/correct` - Correct identity drift
- `POST /api/v1/ilie/identities/:identityId/layers` - Add identity layer
- `POST /api/v1/ilie/identities/:identityId/align` - Align identity layers

## Drift Correction

When identity drift is detected:
1. Measure drift against threshold
2. Recalculate unified identity from current layers
3. Apply automatic correction
4. Update all layer mappings
