physics_freeze_words.c, dictionary_heat_diagnostic_words.c, physics_diagnostic_words.c, physics_benchmark_words.c treated dsp as a count (data_stack[dsp++] push, data_stack[--dsp] pop) while the VM's dsp is the top index. On an empty stack a push wrote data_stack[-1], 8 bytes before the VM struct -- POST's DECAY-RATE@ test did it every boot (on aarch64 it hit parity.c's counter, elsewhere the POST block RAM tail). All 28 sites now use vm_pop/vm_push; four one-item guards fixed (dsp<0). Evidence on amd64/aarch64/riscv64: bytes before the VM struct unchanged across POST; DECAY-RATE@ leaves 1 item; LOOKUP-STRATEGY! now works; G interleave, precedence, console under load, relay 3, dict_hash unchanged.

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}).
