Captain Bob, 2026-10-14: "v4 is the default build", "no, qemu to v4 too ... we are effectively trying to retire v3", "the 32 bit build needs to go into the acceptance test too", "i don't care about v3". - STARFORTH_V4 defaults on (Kconfig default y) and V4_DEFAULT=1 everywhere: every kernel carries v4 and v3 and boots v4; system=v3 boots v3; STARFORTH_V4=0 builds v3 alone. Board images write system=v4. - Acceptance (CLAUDE.md): the three ISAs as built (v4, POST passed, V4_SYSTEM dict_hash equal) and make -C v4 test-32. v3 is not part of it. Acceptance run: amd64, aarch64, riscv64 -- PARITY:V4_POST 538/538, dict_hash=0xe5a57f3eb72ff94a on all three, no unknown word; test-32: 30 suites, 0 failures. The SER5 image under OVMF boots v4 as built, v3 after the one-word edit. README, BRINGUP, FABRIC-3 XLIII, the register updated. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

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
docs/working/experiments/ instead — this top-level directory is
specifically the kernel/bare-metal side.
