This requires 1) that everyone has access to the tracker, 2) the link remains active, and 3) people will take the time to visit something else entirely to get context.

Code is a specification for execution. It should include everything needed to fully execute and understand it.

This is why even microchip makers put much of the SPI signal specification into each datasheet despite SPI being a super common protocol. The more your code's comments act as a datasheet, the better longevity it'll have.
