The Yosemite High Route is another High Route created by Andrew Skurka (refer to https://andrewskurka.com/adventures/yosemite-high-route/ for details). It officially starts in the Yosemite backcountry - the "northern terminus" is Grace Meadow, in the far northern section of the park (on the PCT), at gps coordinates of approximately 38.14846, -119.61116, where a creek from the east joins Falls Creek. This is where the FKT begins. You must access this point by foot, and that time is not included in the FKT.

CR-30 S terminus of Core Route at Merced River
The FKT ends at "CR-30," the southern terminus, which is in the backcountry at approximately 37.73740, -119.44910, and time recorded on the FKT site stops here. It does not include getting back to a trailhead.
As with other high routes (Sierra High Route, Wind River High Route, etc.), most of the "core route" is off-trail (about 70% in this case) and there is no defined route or course, except when the route overlaps with a trail (about 30% of the time while on the "core route"). The FKT site will not publish detailed gpx tracks of the route, however detailed gpx tracks must be submitted for verification that the waypoints listed here are included in the chosen route.
