CARD_COUNT IS 29, NOT 28, AND THE BASE PAGE IS THE SHORT ONE. tcdb sid 180328 states "Total Cards: 28" and renders exactly 28 rows - self-consistent, and still short. The set's own Gold (180330) and Platinum (180331) tiers each state 29 and render 29, their KS- codes being a strict superset of the base page: both carry KS-TPC Taurean Prince, which the base page lacks. checklistcenter independently states "29 Cards - Serial Numbered #/159 or as Noted" and cardboardconnection independently states "Keystone Signatures Set Checklist: 29 cards." So four renderings from three lineages say 29 and only tcdb's base page says 28. Per-card VARIABLE print runs - the distinct token set over the 28 rendered base rows is {SN159 x21, SN99 x4, SN25 x3} - so no print run is recorded here; see gaps. A 2017-18 rookie-class autograph set (dacardworld: "Keystone Signatures represents the 2017-18 rookie class!"). Autographed, so set_type=auto.

This set has a recorded count of 29, but the card-by-card checklist is not yet in the catalogue. That's an open research question, not a statement that no checklist exists. If you know a source that documents it, tell us — a pointer to one is exactly what closes these.
