Robert Allan JamesandClaude Sonnet 5 c2f1d94c97 Artemis Milestone 2c: xHCI controller bring-up wired, DoE CSV export off by default
xhci_bringup() (HC reset, DCBAA, Command/Event rings, RUN/STOP) was
uncommitted and referenced an XHCI_WAIT_FOR macro that was never defined,
breaking the build. Wired all four wait sites to the existing
xhci_wait_bit() helper instead, matching each register/bit/polarity
needed (halt-before-reset waits for HCH set; HCRST, CNR, and post-RUN
HCH waits all wait for their bit to clear).

Also flipped g_doe_log_enabled's default from 1 to 0 -- the per-tick
[HADES][DOE] CSV export was flooding every boot log and slowing
interactive verification for no reason during ordinary acceptance runs;
HB-ON still re-enables it at the REPL for anyone running an actual DoE
campaign.

Three-arch acceptance: amd64/aarch64/riscv64 all boot clean to ok>,
zero DoE rows in any log. aarch64 and riscv64 both exited cleanly via
BYE with no exception, confirming the earlier SMC->HVC PSCI fix still
holds. Logs and DoE CSV artifacts from this run included.

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. See experiments/bare_metal/README.md for 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.
