My prescriber ordered three tests and this board recommends about twenty, and I would like to know which of those two lists is right.
What I am after is what actually belongs on a baseline panel, as opposed to the enormous list that gets pasted around here.
I have searched first, so if this is covered somewhere point me at it and I will read it.
Short answer first, then the reasoning. Quarterly for the first year is convention rather than evidence, and it is defensible for a simple reason: it is roughly the interval over which HbA1c becomes informative again, since it reflects about three months of glycaemia. After the first year, and once doses are stable, annual is reasonable unless something specific is being followed.

Agreed, and reference ranges are laboratory-specific. Comparing your number to somebody else's range, or to a screenshot from another country, is how people convince themselves something is wrong.
I would rather be corrected than agreed with, if it comes to it.

This matches mine closely enough to be worth saying so. A defensible baseline is short: HbA1c and fasting glucose, a lipid panel with ApoB if you can get it, ALT and AST, creatinine with eGFR, TSH, ferritin and B12, and a full blood count. That set catches the things that change, the things that explain symptoms, and the things that alter the prescribing decision. Almost everything else on the long circulating lists is either invariant, uninterpretable without a specific question, or an incidental finding waiting to cause an unnecessary workup.
Adding the clinical framing, because it changes how the question reads.
PSA: get baseline labs BEFORE starting baseline bloodwork therapy. You need a "before" picture to measure progress. My recommended pre-treatment panel:
