Live and on-demand supplies
Supplies come in two flavours, and knowing the difference saves a lot of confusion. An on-demand supply starts producing its values afresh for each tap, like replaying a recording. A live supply broadcasts values as they happen to all current taps, like a radio station — if you tune in late, you miss what already aired.
This section shows both kinds and when each one is what you want.
