## ADDED Requirements

### Requirement: SCUM local debug run distribution proof
The local debug smoke fixture SHALL register the first-party SCUM plugin with enough safe platform metadata for SCUM run distribution APIs to be exercised.

#### Scenario: SCUM run generation is available
- **WHEN** local debug smoke registers `game.scum` and creates `scum-alpha`
- **THEN** `GET /api/v1/server-instances/scum-alpha/runtime/actions` MUST report `generate-run` as available

#### Scenario: SCUM run package is generated
- **WHEN** local debug smoke calls `POST /api/v1/server-instances/scum-alpha/run/generate` for Windows AMD64
- **THEN** the response MUST include an artifact ID and checksum without exposing raw keys, host paths, direct sockets, bearer credentials, or plugin-owned transport details

#### Scenario: SCUM run package generation is idempotent after a partial artifact write
- **WHEN** `POST /api/v1/server-instances/scum-alpha/run/generate` is retried with the same idempotency key after the deterministic artifact already exists but the run distribution row is missing
- **THEN** the platform MUST reuse the matching artifact, create or return the run distribution, and MUST NOT return `duplicate_resource`

#### Scenario: SCUM run self-update dispatch is idempotent
- **WHEN** `POST /api/v1/server-instances/scum-alpha/run/update` is retried with the same artifact, checksum, and idempotency key
- **THEN** the platform MUST return the existing update job and MUST NOT return `duplicate_resource`
