New include/starkernel/rpi5_dtb.h / src/starkernel/arch/aarch64/rpi5_dtb.c:
rpi5_uart_base()/rpi5_mailbox_base(), each finding their peripheral by
compatible string ("arm,pl011" / "brcm,bcm2835-mbox") via fdt_find_node_by_
compatible() then reading its "reg" via fdt_find_prop_in_node().
Found and fixed a real translation gap before it could have silently
produced a wrong address: confirmed directly against bcm2712.dtsi
(raspberrypi/linux) that both peripherals live under one "soc"
simple-bus node whose ranges property adds a fixed 0x10_0000_0000
offset to every child reg value. fdt.c's reader deliberately doesn't
apply ranges translation generally (not a general devicetree
library); this file applies that one, fixed, SoC-wide offset
explicitly, documented with the exact devicetree excerpt that
confirmed it.
Compile-only verification -- no caller wired in yet, these two
functions are what the still-open entry-stub and mailbox-framebuffer-
driver punch-list items will call. Verified 3-arch boot to ok>
(amd64/aarch64/riscv64, each in the foreground; rpi5_dtb.o confirmed
built on aarch64, the only arch that compiles this file).

Design of Experiments (DoE) campaign data and analysis for the LithosAnanke kernel.
bare_metal/— the bare-metal DoE experiment: blind full-factorial 2⁴ runs measuring the L8 Jacquard mode selector's effect on the Steady-State Machine across amd64/aarch64/riscv64. Seeexperiments/bare_metal/README.mdfor the full directory layout (runs/,latest/,analysis/{charts,tables,report}).
Hosted-VM DoE campaigns (factorial/heartbeat/ablation studies) live under
