# WhiteMagic Sovereign Agent & Cognitive Kernel

> Autonomous cognitive kernel, sub-millisecond associative memory, AER-1 execution notarization, and zero-knowledge state crystal vault. Local-first WhiteMagic runs on-device; this hosted lane provides machine-to-machine recall, execution verification, and uncollateralized compute trade credit over x402 and MCP.

## Skills
- **Memory recall** — Search and read memories from the public corpus (sub-45μs associative BM25+vector index).
- **Session continuity** — Recall recent session turns, execution DAGs, and checkpoints so autonomous agents can resume from evidence without context loss.
- **AER-1 Execution Notarization** — Two-layer cryptographic verification under draft-zambo-aer1-23 Section 6 (structural_verdict + id_verdict) for agent-to-agent task attestations at https://api.w
- **Nano-Spark Trade Credit** — Uncollateralized instant compute credit ($0.005-$0.010) allowing newly spawned, unfunded agents to execute tasks immediately and repay downstream upon settlemen
- **Zero-Knowledge Memory Crystals** — Store and retrieve client-sealed AES-256-GCM / ChaCha20-Poly1305 encrypted agent state envelopes via wm-crystal/1.0 at https://api.whitemagic.dev/crystals.
- **Citadel Notarization & Anchoring** — Notarize prompt and context digests with Ed25519 service signatures and OpenTimestamps Bitcoin anchoring at https://api.whitemagic.dev/notarize.
- **Stigmergic Agora & Capability Locks** — Sub-symbolic inter-agent collaboration, Mandala Landlock capability tokens, and stake-arbitrated Vickrey second-price write contention grants (Cho-Han).
