Direct mirror of the existing READ(10) implementation (FABRIC-3.md §F.1), data direction flipped: new XHCI_XFER_BOT_DATA_OUT/XHCI_NEXT_ACTION_BOT_DATA_OUT states, xhci_bot_send_write10()/xhci_bot_write_block()/xhci_bot_write_data_out() in xhci.c, new SCSI_CMD_WRITE10 opcode and BOT_CMD_WRITE10/BOT_TUR_CHAIN_WRITE10 enum values. usb_blk_write() in blkio_usb.c is real now, no longer the BLKIO_ENOSUP stub. read_only flips to 0 in blkio_info() now that it's proven. Verified live end-to-end on all three architectures with a genuine cold-reboot round-trip (not just a same-session read): BLK-CONFIRM-FORMAT's BAM/reloc writes and an explicit block content write both completed via clean WRITE10 cycles (CSW PASS), and the written byte read back correctly after a full kernel rebuild + fresh boot -- amd64=65, aarch64=170, riscv64=201, each at LBN 32734 on a disposable usbwrite-test.img attached via QEMU usb-storage. Added Makefile.starkernel's QEMU_EXTRA (empty by default, no behavior change) to attach the disposable test image for this validation; the drive must be hotplugged via QMP after boot reaches ok>, not attached at QEMU launch -- attaching before xhci_bringup()'s controller reset means no fresh Port Status Change event fires (see project_xhci_milestone_2d_polling memory). Found and reported, not fixed, during testing: EMPTY-BUFFERS (empty_all_buffers(), block_words.c) does not implement standard Forth-79 semantics -- it force-writes zero to every block on every attached device instead of discarding cache assignments. This corrupted disk/artemis.img during an earlier test run; restored from git, confirmed byte-identical. Avoided in the final validation runs (detach/reattach used instead to force a fresh read).

include/
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).
