- 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/starkernel/
Headers for LithosAnanke, the bare-metal UEFI kernel (src/starkernel/).
Built only via Makefile.starkernel; gated by __STARKERNEL__ when shared
with hosted code.
uefi.h— UEFI protocol/type definitions consumed by the loader.elf64.h,elf_loader.h— ELF64 parsing and kernel-image loading.boot_info_offsets.h— struct-offset constants shared between the assembly bootstrap and the C boot path.arch.h,apic.h,timer.h— architecture init, APIC interrupt controller, timer (TSC/HPET/APIC, 100 Hz heartbeat).console.h,framebuffer.h,vt100.h— UART 16550 console, framebuffer driver, and VT100 terminal emulation over the framebuffer.pmm.h,vmm.h,kmalloc.h— physical memory manager (bitmap allocator), 4-level x86_64 paging, kernel heap allocator.pci.h,virtio_blk.h— PCI enumeration and the VirtIO block device driver (disk backend for the kernel block subsystem).capsule.h,capsule_birth.h,capsule_loader.h,capsule_run.h,capsule_vm_physics.h,capsule_generated.h— capsule system types, birth protocol, physics-runtime capsule bindings, and the build-time- generated capsule directory (seetools/mkcapsule.c).kernel_args.h,cmdline.h— boot-time kernel argument parsing (starforth.cfg/ command line).repl.h— kernel REPL.log.h,doe_log.h— kernel logging and DoE metrics logging.q48_16.h— kernel-build copy of Q48.16 fixed-point arithmetic.xxhash64.h— content-addressing hash used for capsule IDs.hal_memory.h— hardware-abstraction-layer memory interface.
Subdirectories:
hal/— top-level hardware-abstraction-layer interface.vm/— kernel VM subsystem headers (capsule arena, parity logging, bootstrap wiring).freestanding/— minimal libc-shim headers (assert.h,ctype.h,errno.h,inttypes.h,math.h,sched.h,signal.h,stdio.h,stdlib.h,string.h,time.h,sys/time.h,sys/types.h) for building shared VM code in the freestanding kernel environment, where no real libc is available.
