Description

Currently, only select VAR is tracked via historical parameters, meaning that when shifting the firstmodelyear a lot of information for example PRICES and total installed capacity are lost and cannot be traced.

Research direction

Start by locating the historical-parameter handling and the VAR tracking logic in the message_ix codebase. Check how shifting firstmodelyear currently preserves parameters, especially PRICES and total installed capacity. Done means all VAR information remains traceable after the shift, with relevant tests or examples updated to verify this behavior.
