C150 MIC KAIZEN SHARDS SUMMARY

C-150: MIC + Kaizen Shards Integration - Implementation Complete ✅¶

Summary¶

Successfully implemented MIC (Mobius Integrity Credits) minting and Kaizen Shards taxonomy as specified by AUREA. The system is now ready for integration into Mobius Systems.

What Was Implemented¶

1. Core Types (packages/integrity-core/src/mic/types.ts)¶

• ShardType - 7 shard types (reflection, learning, civic, stability, stewardship, innovation, guardian)
• KaizenShard - Shard data structure with context
• MicMintContext - Input for minting calculation
• MicMintResult - Output with minted amount and statistics

2. Configuration (configs/kaizen_shards.yaml)¶

• Shard weights configuration
• MII threshold (0.95)
• Per-cycle caps for abuse prevention

3. Shard Weights Loader (packages/integrity-core/src/mic/shardWeights.ts)¶

• YAML config loader with fallback defaults
• Caching for performance
• Flexible path resolution for workspace structure

4. MIC Minting Logic (packages/integrity-core/src/mic/micMinting.ts)¶

• computeShardValue() - Weighted shard value calculation
• aggregateShards() - Total value and counts by type
• mintMic() - Core formula: MIC = max(0, S * (MII - τ))

5. Ledger Integration Service (packages/integrity-core/src/mic/micMintService.ts)¶

• MicMintService class for ledger integration
• LedgerClient interface for abstraction
• Event types: KAIZEN_SHARD_EARNED and MIC_MINT
• Atomic transaction support

6. Package Updates¶

• Added js-yaml dependency
• Added @types/js-yaml dev dependency
• Exported all MIC modules from index.ts

7. Documentation¶

• README with usage examples
• Implementation summary
• Example code demonstrating minting scenarios

Key Features¶

✅ Shards are always recorded - Historical facts regardless of MII
✅ MIC only mints when MII ≥ threshold - "Noise can exist but cannot earn"
✅ Configurable weights - Tune via YAML without code changes
✅ Type-safe - Full TypeScript support
✅ Ledger-ready - Service layer for easy integration

Formula¶

MIC_minted = max(0, S * (MII - τ))

Where:
  S   = total weighted shard value
  MII = Mobius Integrity Index (0.0 - 1.0)
  τ   = integrity threshold (default: 0.95)

Example Calculation¶

Input: - 3 reflection shards (weight=1.0) = 3.0 - 1 civic shard (weight=1.5) = 1.5 - 1 stability shard (weight=2.0) = 2.0 - Total S = 6.5 - MII = 0.97 - τ = 0.95

Output: - MIC = 6.5 × (0.97 - 0.95) = 0.13 MIC

If MII drops to 0.94: - Shards still recorded ✅ - MIC = 0 (below threshold)

Next Steps for Integration¶

1. Implement LedgerClient - Connect to your ledger backend

   class MyLedgerClient implements LedgerClient {
     async runInTransaction(callback) {
       // Your transaction implementation
     }
   }
   

2. Python Bridge (if needed) - Create HTTP API or Node.js bridge for Python ledger-api

3. Testing - Add unit tests for:

4. Minting calculations
5. Edge cases (empty shards, MII below threshold)

6. Shard weight variations

7. Documentation Updates - Update tokenomics docs to reference MIC (already mentioned in some docs)

Usage¶

import { mintMic, MicMintContext, KaizenShard } from '@civic/integrity-core';

const context: MicMintContext = {
  citizenId: 'citizen-123',
  cycleId: 'cycle-150',
  miiScore: 0.97,
  shards: [/* ... */],
  now: new Date(),
};

const result = mintMic(context);
console.log(`MIC minted: ${result.mintedMic}`);

Status¶

✅ Complete and Ready for Integration

All core functionality implemented as specified. The system is type-safe, well-documented, and ready to be wired into the ledger-api or other Mobius services.
