vm_find_word() and dict_find_word_heat_aware() reference the same extern globals (sf_fc_list/sf_fc_count/sf_fc_cap) but GCC compiled cross-TU references to them with GOT-indirect addressing (R_X86_64_REX_GOTPCRELX) under -fPIC. This freestanding, statically-linked UEFI PE image has no dynamic linker to populate a GOT, so those reads silently returned NULL instead of the array's real address -- amd64-only, and exquisitely sensitive to unrelated code-size changes since the choice between direct and GOT-indirect addressing is a per-call-site GCC heuristic. Fix: -fno-pic -fno-pie for amd64 only (ARCH_CFLAGS, overriding COMMON_CFLAGS's -fPIC, which riscv64's -shared loader link still needs). Also removes -DPLATFORM_TIME_NO_INLINE, a prior one-off workaround for the identical bug applied to sf_monotonic_ns() specifically, now redundant. Adds R_X86_64_PC32/R_X86_64_PLT32 handling to elf_apply_relocations() as a robustness fix for the non-monolithic split-build path (dead code for the current monolithic boot, where OVMF's own PE loader relocates the image, not this loader). Verified: all three architectures boot clean and pass the full item-4.2 Hermes self-test, including MSG-DELIVER-ALL, which previously triggered the corruption on amd64 only. Write-up in FABRIC.md under item 4.2. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
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.
