Punch list §25 item 3.1 complete. Defines StadiumPatronHeader and StadiumContinuationCell in new include/starkernel/vm/stadium.h, unioned as StadiumCell per §3's closed two-valued union. src/starkernel/vm/stadium.c added to Makefile.starkernel's LOADER_EXTRA_SRCS/KERNEL_EXTRA_SRCS so the header's compile-time size checks are actually compiled, not merely included by something that never builds. Discriminator ruled an external side bitmap (Captain Bob), not a header field -- amended into §3 and §23.3 before this code was written. Item 3.1 declares the bitmap's purpose/indexing in a comment only; allocating it is item 3.2's scope. Both cell shapes counted for real at exactly 64 bytes with zero compiler-inserted padding (three C99-portable negative-array-size assertions -- no _Static_assert, this project targets C99). Header matches §23.3's original 32+32 split unchanged, since the discriminator moving outside the cell left nothing to compete for that space. Continuation cell matches item 1.12's 4+60 figure unchanged for the same reason. Verified the size assertion is actually live: broke it to 63, confirmed the build failed with the expected negative-array-size error, restored it, confirmed a clean compile. Verified: three-architecture boot (amd64, aarch64, riscv64), all reaching ok> with identical dict_hash=0x3d4e1daf289da94f matching the item-2.2 baseline. Confirmed stadium.o present in both obj/loader/vm and obj/kernel/vm post-build on amd64, closing the gap the item-2.2 WIP exposed (an uncompiled header proves nothing). Left open, not fabricated: §23.4 #2 ("does a typical message fit in one cell") is unanswerable today -- no message patron struct exists anywhere in this tree yet.

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.
