launch targets, three-arch verified Makefile.starkernel: added -qmp unix:$QMP_SOCK,server=on,wait=off to the amd64/aarch64/riscv64 qemu targets, matching the existing serial chardev socket pattern exactly (same discoverability, same cleanup on exit). Verified on all three architectures: QMP greeting arrives on connect, qmp_capabilities handshake succeeds, device_add/device_del round-trip correctly. Real finding surfaced during device_add testing (recorded in FABRIC-2.md's punch list for Milestone 2): the q35 machine's pcie.0 root bus doesn't support runtime PCI hotplug without a bridge -- Milestone 2's qemu-xhci USB controller needs to be present in the static launch command, with USB devices hot-attached to its bus at runtime, not the controller itself hot-added. Also noted: g_doe_log_enabled's default-on per-tick heartbeat CSV export was briefly mistaken for a hang during aarch64 verification -- it isn't one, just a large volume of routine diagnostic output before reaching ok>. Not changing the source default; adopting HB-OFF immediately after boot as the working pattern for the rest of this punch list's dev work. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
capsules/
FORTH personality files loaded by the VM at boot. A capsule is an immutable, content-addressed payload; its XXHash64 hash is its identity. Any mutation changes the hash and the birth protocol rejects the image.
