"""
genesis_types.manifests — Pydantic models for Genesis agent and capability manifests.

PURPOSE:
    Defines the canonical schemas for:
    - AgentManifest: Describes a Genesis agent (capabilities, model, context)
    - CapabilityManifest: The current runtime capability state of Genesis OS
    - MCPServerManifest: A connected MCP server and its tools
    - ModelSpec: A specific LLM model's specs and limits

    These manifests implement RULE 10 (Capability-First Protocol) from
    GLOBAL_GENESIS_RULES.md — agents MUST audit their capabilities before
    any mission.

CAPABILITY MANIFEST FILE:
    Written to: /mnt/e/genesis-system/data/context_state/capability_manifest.json
    Updated by: .claude/hooks/capability_audit.py at session start
    Read by: All Genesis agents at startup

RELATED FILES:
    /mnt/e/genesis-system/KNOWLEDGE_GRAPH/entities/genesis_capability_state.jsonl
    /mnt/e/genesis-system/.claude/hooks/capability_audit.py
    /mnt/e/genesis-system/data/context_state/capability_manifest.json

TODO:
    - Implement AgentManifest Pydantic model
    - Implement CapabilityManifest Pydantic model
    - Implement MCPServerManifest Pydantic model
    - Implement ModelSpec Pydantic model
    - Add load_capability_manifest() helper function
    - Write tests for manifest loading + validation
    - Write tests for backward compatibility (older manifest versions)
