WalkthroughThe change removes unused helpers, fields, constants, embedded assets, compatibility paths, and test fixtures across development tools, controllers, daemon code, operator code, and end-to-end tests. It also adjusts SSH and image-update behavior and expands node reconciliation coverage. ChangesRepository cleanup and validation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The change can cause the template controller to panic during startup when the optional IRI path is disabled, preventing the controller from starting; this issue should be fixed before merging. 🚥 Pre-merge checks | ✅ 14 | ❌ 1❌ Failed checks (1 warning)

- What I did
This removes all unused functions and constants found by running
golangci-lint run --enable-only=unused ./...and remove all unused parameters and returns found by runninggolangci-lint run --enable-only=unparam ./.... Note thatgolangci-lint run --enable-only=unparam ./...also highlights parameters for functions that always recieve the same value. I did not remove such parameters to ensure future flexibility with the parameter options.- How to verify it
To ensure all functionality remains the same:
To ensure cleanup is complete:
