How well does graphite on paper age? If it isn't rubbed and just sits

putting something in a time capsule, the note must be handwritten and
placed between two panes of glass with 1/8" (3mm) space.

Probably too late - but - the graphite will last for years - I've been doing some historical research recently - looking at documents 150 plus years old which have contemporary
pencil annotations.
The paper is probably the key thing - modern papers tend to be more acidic and prone to decay (high wood pulp - low linen content) - invest in some archiving paper - and the document will last for decades or more.
