Build a purchase ledger
Record item/upgrade names as they are confirmed in your own game and mark purchased status. Avoid guessing the final stock count from an early shop state.
Separate unlock state from affordability
If an item is visible but unaffordable, that is a resource problem; if it is not visible yet, that may be a progression problem. Tracking those states prevents unnecessary grinding.
Recheck stock after major progression
Shop inventories can be progression-sensitive in many games, so use major story milestones as natural moments to re-audit the Traveler rather than repeatedly checking after every room.
Confirm the buy-all trigger
Before farming more resources, verify that every visible and progression-unlocked purchase is owned and that the completion goal has registered.
Core game facts are limited to the official Steam store/demo and official Steam news; achievement-specific scope is based on released platform achievement metadata.
