Ruled by Captain Bob, 2026-11-07: "New root CA on the CI box. Valid StarshipOS rather than snake oil intermediate." - ci/pki/make-ca.sh makes the StarshipOS Root CA (its key stays on the CI box) and the StarshipOS Capsule Signing intermediate it issues, and stores the signing key as the secret CAPSULE_SIGN_KEY. - The kernel finds the signing certificate by one name, CAPSULE_SIGNING_CERT_NAME = pki:starshipos-intermediate.der. The certificate itself lands once make-ca.sh has run; until then the snakeoil intermediate is in the tree under its old name and the capsules check as "no root key" (a warning, as "missing" was). - mkcapsule refuses a signing key that is not that certificate's. - SIGN_KEY has no default; acceptance, build, nightly and release set it from the secret.

LithosAnanke — the bare-metal UEFI kernel that boots StarForth directly on
hardware (amd64/aarch64/riscv64). Built only via Makefile.starkernel; the
only valid acceptance test is the three-arch QEMU boot (see
.claude/CLAUDE.md), never make test.
kernel_main.c— kernel entry point, driving the boot milestones (console init, PMM, VMM, interrupts, timers, kmalloc heap, VM bootstrap).repl.c— kernel REPL.doe_log.c— kernel-side DoE (Design of Experiments) metrics logging.
Subdirectories:
arch/{amd64,aarch64,riscv64}/— per-architecture support (APIC/GIC/ PLIC interrupt controller, timers, boot/ISR assembly).boot/— UEFI loader, ELF loading, kernel command-line parsing.capsule/— capsule birth/run/load/validate pipeline.hal/— hardware-abstraction-layer implementation (console, framebuffer, VT100, memory, host services).hash/— XXHash64 content-addressing implementation.math/— kernel-build Q48.16 fixed-point arithmetic.memory/— physical/virtual memory managers and the kernel heap.pci/— PCI bus enumeration.virtio/— VirtIO block device driver.vm/— kernel VM subsystem (bootstrap, core interpreter, parity logging, capsule arena).
