Shard Token — AIPayHQ
Sub-Agent Delegation

Shard Token
Restricted Scope Inheritance

When a primary agent spawns a sub-agent, a shard token is issued from the parent certificate. The shard inherits a restricted subset of the parent scope. A sub-agent cannot receive equal or elevated rights through delegation — the parent cannot grant what it wasn’t itself authorized to do.

Every delegation event is logged to an audit chain, illustrated here as WitnessBound. “Audit-ready” describes the pattern’s design intent — it isn’t a claim of formal regulatory certification.
