Per-slot registry (xhci_msc_slot_t/dev->msc_slots, sized off the controller's own reported max_slots) replaces the single-device scalar fields the driver carried since Milestones 2e-2h. Boot-time port scan no longer stops at the first connected device; a connect/disconnect that arrives while the Command Ring is busy is now queued and drained instead of dropped. blkio_usb.c and repl.c's own single-device state (device descriptor buffers, blkio_dev_t, attach bookkeeping) became per-slot registries the same way. Live multi-device testing (not just compiling) surfaced a second, more severe bug outside the original plan: transfer_purpose and next_action were also single scalars shared across the whole controller. Two devices enumerating concurrently could have one's completion silently overwrite the other's still-outstanding one, permanently stalling it with no error. Fixed by moving both per-slot and, critically, reading the Transfer Event TRB's own real Slot ID field instead of trusting external bookkeeping. Verified live, all three architectures, mandatory clean-qemu acceptance: existing single-device path unchanged, and two devices attached simultaneously (amd64) both progress independently through enumeration without corrupting or stalling each other. Also in this pass (implemented and verified in earlier turns this session, committed together per direct instruction): - Headless-until-login console policy: no prompt/banner until a real identity logs in via an attached thumbdrive (WIREBIND or Zuse, neither special), reusing EMERGENCY_CONSOLE_ENABLED as the debug/recovery escape hatch (now default-off). - KILL/g_repl_active_vm dangling-pointer fix: killing the VM the console is currently USE'd onto now detaches back to Hera first, matching the existing EJECT/UNCLEAN precedent. FABRIC-3.md §VII/§VIII carry full closure notes for all three. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_018EjXFo7mPXjUMjfJeuUUz4
