Verify removal of rank, trust, and pruning_score from runtime and chain state #2396
Description
Verify removal of rank, trust, and pruning_score from runtime and chain state
Summary
The fields rank, trust, and pruning_score were previously identified as unused or obsolete, but it is unclear whether they have been fully removed from runtime logic and chain state.
Problem
- Some fields appear unused in production logic.
- It is unclear whether these fields still exist in storage or metagraph outputs.
- SDK breaking changes depend on confirmation of removal.
Current Status
- Pruning logic was partially reworked.
- Registration changes are still in progress.
- Removal status of these fields has not been confirmed.
Expected Outcome
- Audit of runtime logic and storage.
- Clear confirmation of which fields remain.
- Removal or explicit deprecation of obsolete fields.
Context
Filed at the request of Rhef to verify current state and unblock follow-up cleanup.
