Governance state, rule results, execution eligibility
ECS does not receive raw Agent output as its ordinary upstream. Its upstream is the status produced by governance and rule review.
Execution Control Stack
ECS
ECS carries the governance state, applicable rule results, and execution-eligibility outcome immediately before the Execution Boundary.
This page explains the public architecture role, relationships, and boundary. It does not disclose implementation mechanisms, interfaces, credentials, or rule packages.
Execution Boundary
The downstream point is the Execution Boundary, where permitted action may become real-world effect.
Keep action controllable before the boundary
ECS holds the execution-control position that ensures the action remains governed before crossing into execution.
Allow, Block, Escalate, or hold state
Public outcome categories may include allow, block, escalate, hold, or route to another governance path.
Not the execution layer itself
ECS is not the Execution Layer. ECS governs whether action may proceed; the Execution Layer is where permitted action takes effect.
