Performance budget

Keep VM load comfortably below 80 percent. Move these behind events/dirty flags:

• full persistent record scans;

• full table transformations;

• display rendering;

• persistence commits;

• repeated platform/identity queries that rarely change;

• repeated calculations whose inputs did not change.

Comments do not consume target bytecode the same way const data and executable code do. Optimize data width and duplicated behavior before deleting useful explanations.
