+## Campsite Rule (MANDATORY)
+
+If you modify a line containing a policy violation, you MUST either:
+1. **Fix the violation properly** in the same change, OR
+2. **Flag it as a deferred item** with documented rationale
+
+**"It was already there" is NEVER an acceptable justification** for perpetuating a violation in code you touched. Touching it makes it yours.
+
+Examples of violations you must fix when you touch the line:
+- `as unknown as Type` double assertions — use type guards instead
+- `any` types — narrow to `unknown` with validation or define a proper interface
+- Missing error handling — add it if you're modifying the surrounding code
+- Suppressed linting rules (`// eslint-disable`) — fix the underlying issue
+
+If the proper fix is too large for the current scope, you MUST:
+- Create a TODO comment with issue reference: `// TODO(#123): Replace double assertion with type guard`
+- Document the deferral in your PR/commit description
+- Never silently carry the violation forward
