pureboot moved to its own repo, so the loader this board hands over to stopped being reachable through a sibling checkout of the bootloader repo. It is a submodule here now: this board has no reset line and no programming header, so the resident loader is the only way in, and the commit naming the firmware should name the loader it has to reach. The reachability check stops carrying its own copy of where that loader is. 0x7e00 was a literal beside pureboot's own geometry, which the submodule exports as PUREBOOT_BASE_HEX - one source for the fact now, and the check reads whichever slot the pinned loader actually has. The boot-section bound stays a literal, being a fuse fact rather than a loader one. Built and tested at both pins on the bench: 5/5, cross-mode identity included, and the image deployed to the board verifies byte-for-byte through its loader.
