## MODIFIED Requirements

### Requirement: Run distribution generation remains asynchronous and server-scoped

The platform SHALL create a bounded `distribution.build` job on the instance deployment target and return a `building` distribution with the real job ID. The generated Run package SHALL contain a server-scoped endpoint identity and component key; a legacy shared builder endpoint MUST be promoted to the deployment target before the job is queued.

#### Scenario: Generate from a legacy endpoint binding

- **GIVEN** an authorized server owner selects a legacy server whose only endpoint is an online build-capable worker
- **WHEN** the owner requests a target-matched Run distribution
- **THEN** Platform queues the build on that worker and assigns the generated package its deterministic dedicated endpoint identity
