- The static sk_hermes_msgs[32] is replaced by a directory of fixed-size segments (SK_HERMES_ARENA_SEGMENT, growth granularity only). Messages never move -- callers, including the drain across vm_interpret_kind(), hold message pointers across later allocations, so copy-on-grow (as §7.0 first proposed) would dangle them. Each message carries its index; numbering unchanged. - Pending-queue rings and channel member lists heap-grown (doubling); member lists freed on destroy; reassembly scratch sized per call. SK_HERMES_MSG_MAX / _PENDING_MAX / _MEMBER_MAX are gone. - Q_SLOT = Q48_ONE / 32 as its own constant (M-0b), value unchanged. - Every grow failure is printed, logged at LOG_ERROR, counted (sk_hermes_grow_failures()) and refused whole; a send whose queue can't grow releases its message. Probe (reverted), identical on amd64/aarch64/riscv64: 70 messages in one queue (arena 32 -> 96), sender refused by its reservoir, 72 popped intact in order, 100 members; a live Hera drain on a full arena grew it mid-drain and released/popped the right message; each grow path's injected failure refused whole and counted. 3-ISA acceptance passes; boot parity, dict_hash set and the live ledger line byte-identical to before.

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.
