plic_init() now takes boot_info->dtb (threaded through apic_init()) and tries fdt_find_node_by_compatible(dtb, "sifive,plic-1.0.0") -> fdt_find_prop_in_node(..., "reg", ...) before falling back to the QEMU-virt-specific constant it previously hardcoded unconditionally. Reuses the node-scoped DTB lookup primitive built for the aarch64 GIC base fix unchanged. s_plic_base is now a runtime uintptr_t, same shape as apic.c's s_gicd_base/s_gicc_base. This system's QEMU/UEFI riscv64 firmware does not forward a DTB to the guest (timer.c's own timebase-frequency read falls back too, confirmed in this boot's own log), so only the no-DTB fallback branch is exercised here -- the success branch (a real DTB with a matching PLIC node) stays unverified until real Milk-V Mars hardware. FABRIC-3.md's first-drafted claim that the success branch would run (based on a stale comment in plic.c's own pre-fix header) was checked against the actual log and corrected before this commit. 3-arch acceptance: amd64/aarch64 don't compile these files, so their runs are non-regression on untouched files only. riscv64's own boot log confirms the fallback path prints exactly as designed and boot reaches zuse)ok> unchanged.

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).
See include/starkernel/README.md for the bare-metal kernel headers.
