[audit] dead-code: Orphaned modules fileOwnership.ts and selectionPulse.ts

[claude]

Problem

Two utility modules exist with full test suites but zero production consumers. They appear to have been built for features that were never integrated.

1. src/utils/fileOwnership.ts + src/utils/fileOwnership.test.ts

Exports: shouldClaimFile, getClaimPriority, FileOwnershipInput, FileOwnershipResult

Grep confirms these are only imported by the test file — no component, hook, store, or plugin uses them.

2. src/utils/selectionPulse.ts + src/utils/selectionPulse.test.ts

Exports: triggerSelectionPulse

Same situation — only imported by its own test file. The visual feedback feature was never wired up.

Impact

• Dead code inflates the codebase and test suite maintenance burden
• Coverage thresholds count these tests, masking actual coverage of live code
• Future developers may assume these features are active

Suggested Fix

Delete both source and test files:

• src/utils/fileOwnership.ts
• src/utils/fileOwnership.test.ts
• src/utils/selectionPulse.ts
• src/utils/selectionPulse.test.ts

If these features are planned for future use, they can be re-added when actually needed.
