The forge · Stage of the build
Final image
Wrought complete. Packages assembled into the bootable system: the fire no longer needs the original forge to stay alight.

Assembly
Assembly takes the Stage 4 package set and installs it into the Stage 3 image skeleton, producing the bootable QCOW2 that ran as Saphira v0.1. Nothing is assembled by hand: the same dependency graph that ordered the builds orders the assembly.
The target for the whole userspace is x86_64-saphira-linux-musl (originally x86_64-akadata-linux-musl when the project was AKADATA Linux), compiled -march=x86-64-v3 with -O3. Reproducibility holds to the end through a fixed SOURCE_DATE_EPOCH.
What comes out is a complete test of the from scratch claim: a musl system with musl's loader in /lib, every binary linked against it, and no path back to the hosts that built it. That result has its own page: Saphira v0.1, the first Dragon.
