An Agent acts via MCP/REST under a scoped key. Its identity is provable and its authority is bounded.

# Schema
- `did` — decentralized identifier (signed)
- `scopes` — string[] (e.g. tasks:read, tasks:write)
- `sponsor` — the human whose authority the agent is a subset of
- `constitution` — the [Constitution](/knowledge/okf/constitution.md) it operates under
