"""
arifOS AAA MCP Server — 5-Organ Trinity + 4 Utilities (2026.02.22-FORGE-VPS-SEAL)

Canonical AAA-MCP server module for `python -m aaa_mcp`.
This module exposes the canonical 5-organ public API and utility tools.

Multi-Transport Support: STDIO | SSE | StreamableHTTP

5-Organ Trinity (Public API):
1. init_session   — Ψ Init & Validate (000_INIT + 555_ASI)
2. agi_cognition  — Δ Mind (222_REASON + 333_MAP + 444_DRAFT)
3. asi_empathy    — Ω Heart (555_IMPACT + 666_ETHICS)
4. apex_verdict   — Ψ Soul (777_FORGE + 888_JUDGE)
5. vault_seal     — F1 Persistence (999_VAULT)

4 Utilities:
- search          — Web search (read-only)
- fetch           — Web fetch (read-only)
- analyze         — Data/structure analysis
- system_audit    — System verification

Legacy 9-subroutine model internalized to prevent abstraction leaks.
All thermodynamic states flow through the 5-Organ metabolic loop.
