- Kernel sf_realloc() is a real realloc (copy min(old,new) via new kmalloc_usable_size(), free old, NULL-on-0 frees). It allocated fresh and nothing else: every growth leaked, and vm_state_push()'s call-state stack lost every saved state past depth 8 (found here). - Shim realloc() copies min(old,new) (over-read when growing). - Defect 9: FC bucket growth no longer leaks or patches a copy; no sf_xrealloc() (freed a block the index still held on failure). - Defect 5: heat snapshot heap-sized (was heats[1024], truncating). - Defect 6: word refused whole when its metrics can't be allocated. - Defect 7: vm_cleanup() (both) frees metrics' inner arrays. - Defect 8: most-likely-next kept incrementally; no full id scan. - Probe (removed): realloc keeps contents, heap returns exactly; call stack depth 20 intact; all three ISAs. Churn criterion NOT met: ~7 KB retained per churned VM (quota slots/word rows -- K-4 re-measures); a post-churn CONSOLE-CMD refusal attributed to the quota leak, K-4 retests. - Standard sequence on amd64/aarch64/riscv64: hashes, G, ledger 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).
