Fix EXEC/LOAD block-persistence gap and WIREBIND/USE interpreter-race panic (FABRIC-3.md §XII)
Found live while building a cross-ISA FORTH-79 dictionary exerciser:

- capsule_exec_init() zeroed a capsule's block content immediately after
  running it, so LOAD (a genuine FORTH-79 standard word, ACL-allowed even
  for locked identities) could never actually read back what EXEC had
  just written. Removed the clear from capsule_exec_init(); block content
  now persists like any other Standard BLOCK/BUFFER/UPDATE write.
  kernel_main.c's own explicit post-birth clear of Mama's init.4th range
  is untouched.

- USE could redirect the console to a WIREBIND identity's VM before that
  VM's vm_enable_interpreter() step of its own birth sequence had run,
  causing the next typed line to hit vm_assert_interpreter_enabled() and
  panic the entire machine -- not the per-session-recoverable ACL-fault
  path a redirected VM otherwise gets. USE now checks interpreter_enabled
  first and refuses with a retry message instead.

Also includes the amd64/aarch64/riscv64 acceptance boot logs and DoE CSVs
from this session.

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 (see tools/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.
