When an agent spawns a sub-agent, your rules need to travel with it — unchanged, enforced before every action, and impossible to quietly relax without leaving a record. That's what OGPP (Operator Governance Protocol) does, across every level of the hierarchy.
Three stages. No human can review every spawn at machine speed — so the protocol does it for them, cryptographically.
The operator signs a Governance Constraint Record — in plain terms, a signed rulebook — containing every constraint: prohibited tools, output limits, resource caps, delegation rules. Mandatory constraints are marked and hash-locked. The record is anchored to the ledger before any agent acts.
When any agent spawns a sub-agent, a Governance Inheritance Binding — think of it as a chain-of-custody stamp proving the same rules were passed down — is generated and anchored to the ledger before the sub-agent executes. The mandatory constraint hash travels unchanged through the entire hierarchy. Any relaxation breaks it, and any third party can detect it.
The Local Enforcement Gate — a checkpoint the agent cannot route around — intercepts every tool call, API request, and message before external effects are produced. Deterministic rule-matching, no LLM inference. Violations are blocked in real time and logged as tamper-evident events.
OGPP is Layer 03 of the AIBrokerAgent accountability stack.
