Advanced review checklist

• One stable owner per piece of state

• One final writer per output

• Raw physical, current working, or previous-cycle final output layer selected intentionally

• Exclusive modes skip normal logic

• State transition precedence documented

• Runtime indexes bounded

• Fixed-point scale and overflow bounds documented

• Save layout versioned and owned

• View/edit/save/cancel separated

• Dirty flags guard rendering and persistence

• BVAR/SPVAR maximum index proven

• Controller and console protocols not conflated

• Const data uses the narrowest safe type

• VM load, bytecode, variable slots, and stack all within limits
