xhci_poll_events()'s Port Status Change connect branch now calls xhci_cmd_enable_slot() directly (the earlier boot-time smoke test call is gone), tracked via a new dev->pending_connect_port_id -- since this driver only ever has one command outstanding at a time, that alone identifies which port a later Command Completion Event answers, without needing to match the Command TRB Pointer yet. On success the returned Slot ID is recorded in a new dev->port_slot_id[], a fixed uint32_t[XHCI_MAX_TRACKED_PORTS] (32) indexed by port. Disconnect clears the port's tracked slot (real teardown -- Disable Slot, DCBAA clear, Section U callback -- is still a later increment). Fixed array, not heap-allocated: a first attempt sized port_slot_id dynamically via kmalloc_aligned(dev->max_ports * sizeof(uint32_t), 64) inside xhci_bringup() and it crashed amd64 with a page fault (IFETCH at RIP=CR2=0xA0000, the legacy VGA hole) during the unrelated Mama-VM-birth phase afterward -- a heap-corruption signature, not chased to root cause. Switching to a fixed array (matching this driver's existing preference for fixed over dynamic allocation) made the crash go away; the crashing boot's log is kept (logs/20260822-102516/) as the evidence trail. Verified live via QMP hotplug, all three architectures: connect -> "enable slot command submitted" -> "enable slot succeeded", with a disconnect/reconnect cycle repeating cleanly and no port wedge.

Public headers for the hosted StarForth VM (src/). Kernel-only headers
live under include/starkernel/.
Core VM
vm.h— theVMstruct and all core types (DictEntry,DictPhysics, stacks, dictionary state); the central header most other files include.vm_api.h— external VM API surface.vm_host.h,vm_debug.h,startup.h,version.h— host integration, debug utilities, startup sequencing, version string.cli.h,repl.h,io.h,log.h— CLI parsing, REPL loop, I/O, logging.word_registry.h— word registration system shared by everysrc/word_source/*.cfile.compudynamics.h— the generic compudynamics module: tuning-word/config lookups (cd_tuning_word(),cd_tuning_vm()) consumed byssm_jacquard.c.
Memory / blocks
memory_management.h,dictionary_management.h— dictionary allocator and search.block_subsystem.h,blkcfg.h,blkio.h,blkio_factory.h— logical→ physical block mapper and pluggable block I/O backends (file/RAM).platform_alloc.h,platform_lock.h,platform_time.h— platform abstraction shims (hosted vs. kernel allocation/locking/timing).
Physics-driven adaptive runtime (7 feedback loops)
physics_runtime.h— main physics coordinator.physics_hotwords_cache.h— Loop #1, execution-heat hot-words cache.physics_metadata.h— per-wordDictPhysicsmetadata tracking.physics_pipelining_metrics.h— Loop #4, word-transition prediction.physics_execution_hooks.h— execution instrumentation hook points.rolling_window_of_truth.h,rolling_window_knobs.h— Loop #2 circular execution-history buffer and its tuning knobs.inference_engine.h— Loops #5/#6, window-width and decay-slope statistical inference.dictionary_heat_optimization.h— Loop #1 heat counters.ssm_jacquard.h— L8 Jacquard steady-state mode selector.doe_metrics.h— Design of Experiments (2^7 factorial) metrics.profiler.h— performance profiling hooks.
Arithmetic / codegen
q48_16.h— Q48.16 deterministic fixed-point arithmetic (used instead of IEEE-754 float specifically to keep cross-architecture behavior bit-identical).math_portable.h— portable math helpers.arch_detect.h,starforth_config.h— architecture detection and the build-flag fallback-default layer (used when a.cfile is compiled by hand withoutmake).vm_asm_opt.h,vm_asm_opt_arm64.h,vm_asm_opt_riscv64.h,vm_inner_interp_asm.h,vm_inner_interp_arm64.h,vm_inner_interp_riscv64.h— per-architecture assembler-optimized inner interpreter (USE_ASM_OPT=1).
