Real, complete verification logic -- not yet wired to any write path. homeblocks_sig_check(dev, sig_start_fblock, out_sig) reads the 4 consecutive 1KB blkio forth-blocks the 4KB header spans, verifies magic -> version -> CRC-64 in order, returns HOMEBLOCKS_SIG_OK/_BLANK/ _BAD_VERSION/_BAD_CRC/_READ_ERROR. Reuses block_subsystem.c's existing CRC-64/ISO (compute_crc64, previously static/file-local, now exposed via block_subsystem.h) rather than a second CRC implementation -- same algorithm already proven via per-block checksums. Takes the header's starting block as a plain parameter rather than resolving it internally: verifies a signature given a location, finding that location (GPT-partition-relative) stays the caller's job. Verified against the actual shipped code, not a reimplementation: a standalone host test links the real homeblocks_sig.c against a fake in-memory blkio_dev and exercises all four outcomes -- blank media, a correctly-minted header (round-trips drive_uuid/minted_time_ns), a flipped CRC, an unrecognized version. All four pass. A full QEMU-hotplug live test isn't proportionate yet since nothing calls this function from the live kernel path -- wiring it into the attach path is the next punch-list item. Clean zero-warning compile and clean boot on all three architectures confirms no build/link regression from exposing compute_crc64 and adding the new source file to every kernel build.

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).
