undiscardable
Must be retained
Something undiscardable cannot be thrown away or gotten rid of—whether physically, emotionally, or practically.
The word often describes possessions with sentimental value, documents that must be retained, or ideas that persist despite efforts to dismiss them: These letters from my grandmother are undiscardable.
In software and gaming contexts, undiscardable items cannot be deleted or removed from inventory.
