description	Safely maintain a forked SS14 codebase with minimal upstream churn. Use when deciding whether to edit upstream files, when extending behavior in `_OpenSpace`, when preserving path similarity, or when avoiding unnecessary changes to RobustToolbox and offs content.

SS14 Upstream Maintenance

Use this skill whenever a change touches inherited upstream code or may introduce avoidable fork drift.

Workflow

1. Open references/edit-strategy.md.
2. Open references/engine-boundaries.md before considering engine or broad upstream edits.
3. Open references/edit-types.md for the expected fork-edit patterns.
4. Open references/path-similarity.md when adding fork-side files.
5. Open references/fork-only-content.md when _OpenSpace may be the right home.
6. Prefer the smallest diff that solves the task.
7. Treat RobustToolbox/ as off-limits unless the task explicitly requires engine work and no content-side path will solve it.
8. Mirror existing folder paths when adding fork-side extensions.
9. Prefer reusable extensions and public APIs over one-off branches, special cases, or hardcoded fork behavior.
10. Mark OpenSpace-specific blocks in files outside _OpenSpace with OpenSpace Edit Start / OpenSpace Edit End.
