this is a dated storage note rather than a declaration that I have solved aging. The comparison is airing: sealed bag versus 48 hours dry airing. musty aroma reduced but white specks unchanged.

Climate and measurement matter here. If your storage is in a different humidity range, please label it. Failure reports are useful too; I would rather know what went wrong than build a shrine to survivorship bias.
