rpi5_native_boot() populates the existing BootInfo struct from the devicetree instead of UEFI protocols, then calls the existing, unmodified kernel_main() -- the crux of why most of M1-M9 stays shared between the UEFI and native boot paths. native_rpi5_entry.S now tail-calls into it instead of halting. memory_map is built from /memory's own reg, honoring the *root* node's #address-cells/#size-cells (confirmed against bcm2712.dtsi's actual root node -- <2>/<2> -- not assumed; a wrong cell width here would compile and boot clean in QEMU while silently corrupting the real memory map on real silicon). Required a new fdt_find_node_by_device_type() since /memory is identified by device_type = "memory" per DT spec, not compatible. args comes from /chosen's bootargs fed into the existing cmdline_parse_ascii() (confirmed pure C99 with no UEFI coupling before reusing it). framebuffer comes from the already-built rpi5_mailbox_get_framebuffer() at a fixed 1920x1080x32 default -- no EDID query exists in this codebase, flagged rather than guessed past. Deliberately scoped out, not silently skipped: /reserved-memory is not parsed. Carving reserved sub-ranges out of /memory's span needs interval-splitting logic that would be written blind against hardware not yet in hand -- exactly the kind of code that hides a bug until real silicon. pmm.c's Pass 3 only ever clears pages this file lists as EfiConventionalMemory, so the gap is "less usable RAM than optimal," never "reserved RAM wrongly marked free." Left as its own future item. Also fixes a real link failure this work surfaced: boot/cmdline.c was only in LOADER_SRCS_BASE (the .efi target), not KERNEL_SRCS_BASE (the separate .elf target arch/aarch64/*.c also wildcards into) -- added it there too. Compile-only-verified; nothing in the existing UEFI/QEMU path calls rpi5_native_boot(), so this cannot be exercised until real hardware. Verified 3-arch boot to ok>/zuse)ok>.

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).
