The overflow-triggered migration path (a WIREBIND-attached identity's own drive running low on space) was scoped but never built -- only the trigger-detection call site was missing, per this section's own text. - capsule_wirebind.c now tracks the attached blkio_dev* alongside the already-tracked VM id, set in try_attach() and cleared in both EJECT/UNCLEAN paths. - New capsule_wirebind_overflow_idle_check(), called once per idle tick in repl.c right alongside blk_migration_idle_check() (same cadence): reads the attached drive's free/total via blk_get_device_free_blocks(), and if free space is below a fixed 10% threshold, extends the identity's pool with a one-time blk_firsttouch_claim() of 8 additional devblocks on Artemis's system-resident device. - New blk_owner_has_claim(owner_fp) in block_subsystem.c answers the debounce question blk_firsttouch_claim()'s own doc comment had left open: a disk scan, not a RAM flag, so the already-extended answer survives reboot/reattach, matching BMAPFMT's "ownership travels with the block" model. Premise checked before building (does a WIREBIND-attached drive actually give a real free/total signal, or does it stay PROVISIONAL/raw): traced repl.c's attach sequence and confirmed blk_subsys_attach_device() runs on the same dev pointer right after WIREBIND, and a WIREBIND-eligible drive is always already STFR/v2-formatted, so the signal is real. Premise held, unlike the BAM item's overstated one. Verified with the mandatory 3-arch QEMU acceptance (identical dictionary hashes, no regression) plus a live logic test of blk_owner_has_claim(): a temporary TEST-OWNER-CLAIM word, run once via SK_CMD and reverted, confirmed it correctly detects the claiming owner and rejects an unrelated one. The low-disk-space-triggers-a-claim path itself is not verified end-to-end -- that needs a real minted WIREBIND-user thumbdrive with deliberately tiny capacity, out of scope for this pass; noted as such in the FABRIC-2.md §I.2 closure note rather than overclaimed.

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.
