ludic.inventory: counts per item kind, a PackRules port (stack_limit), add what fits / take all or none / set outright, an ItemChanged queue, and a save section keyed by item NAME so a game can reorder its items with no migration. ludic.wallet: earn, spend only what is there, lose down to zero, set, a MoneyChanged queue and its own save section. Six and five test blocks. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
