## 1. OpenSpec Artifacts

- [x] 1.1 Create proposal, design, and spec delta for plugin-owned SCUM lifecycle ownership.
- [x] 1.2 Validate the OpenSpec change strictly before completion.

## 2. Plugin Lifecycle Assets

- [x] 2.1 Add SCUM-owned Windows install/update and start scripts/action specs with SteamCMD app update and startup arguments owned by the plugin.
- [x] 2.2 Update plugin manifest/tests so SCUM lifecycle no longer depends on `deployment.scum.v1`.

## 3. Platform Dispatch Boundary

- [x] 3.1 Remove SCUM-specific deployment plan creation, capability gating, and evidence validation from platform lifecycle dispatch.
- [x] 3.2 Update platform tests/protocol docs to assert generic plugin action dispatch.

## 4. Run Executor Boundary

- [x] 4.1 Remove the SCUM-specific run executor/capability path and reject legacy `serverDeploymentPlan` inputs generically.
- [x] 4.2 Update run tests to prove generated run capabilities exclude `deployment.scum.v1` and generic plugin actions still execute.

## 5. Verification And Delivery

- [x] 5.1 Run focused plugin, platform, and run tests.
- [x] 5.2 Run `scripts/check-structure.sh` and final repository status checks.
- [x] 5.3 Commit and push main-repo and run-repo changes separately.
