Skyrim ship gate

Required gates

1. Version gate: active version, changelog, and ownership are correct.
2. Diff gate: no unrelated or deployed files were modified.
3. Plugin gate: run forge plugin-info and skyrim-plugin-authoring/scripts/audit_plugin_headers.py for every plugin. Header success is structural only.
4. Papyrus gate: changed scripts compile and packaged PEX files match the current build.
5. Runtime-config gate: structural and semantic audits pass; installed framework versions are recorded.
6. Native gate: every supported DLL target builds and its dependencies are inspected.
7. Asset gate: referenced paths exist and generated outputs are identified.
8. FOMOD gate: XML parses and referenced sources exist.
9. Archive gate: run scripts/validate_release_tree.py; inspect the final root manually.
10. Disclosure gate: list in-game or GUI tests that were not performed.

Target-aware plugin gate

Accept HEDR 1.70 or 1.71 when it matches the declared runtime/backport target. Reject an unexplained mismatch, not either value in isolation. Apply the legacy 0x800-0xFFF or extended light-ID policy accordingly.
