#189, ENGINE step 4, Phase 1 (plan 2026-11-13-engine-step4-phase1), Tasks 1-4. Captain Bob, 2026-11-13: Q1 "A new node key", Q2 "Per heartbeat tick", Q3 "All of v3's", Q4 "In Phase 1" / "Full births now", who runs next "Hera by compudynamics now" (Task 5, to come). - stadium.c/.h: stadium_node_key(node) ("NODE" | number), stadium_boot_init_for(first), stadium_birth_node(key, name); stadium_boot_init() and stadium_birth_hera() are them for Hera's key, so v3's path is as it was (only an impossible panic's words changed). - kernel_main.c: the system is chosen and said first, then the Stadium, sessions, switch-signal and kernel-Hermes tables for both systems in v3's order; v4: Hera, node 10, patron zero under her node key, the word, block and opcode layers. The quota self-test and the heartbeat's line are functions now, called by both systems. - sk_v4.c/.h: sk_v4_run() goes -- sk_v4_boot() returns, the kernel's checks after POST (opcodes, words, conservation, quota, heartbeat), then sk_v4_prompt(). sk_v4_charge_opcodes() at the heartbeat's service points (the key wait, after each line) and once after POST. - stadium_ops.c/.h: a node's 32 opcodes as Stadium patrons (HEAT-OP's feed, "Both"): retirements charged as the word layer's dispatches, a quantum each, the reservoir's floor kept, shared by retirements when short; cooling per tick as words. ~0.5 us a charge on the host: kept. - qemu_session.py: a v4 acceptance boot fails without "Stadium: N cells", "Stadium conservation: CONSERVED" and the heartbeat's ticks (#189). Tests first (logs/20261113-122142): the physics check failed on the v4 boot; test_stadium_node, test_stadium_ops (and its share case, after a real boot showed ";" taking all the heat) failed before. Now: kernel host tests all pass; amd64 v4 boot passes, POST 539/539, dict_hash unchanged, "Stadium opcodes: 30 resident, hottest opcode 8", CONSERVED; a system=v3 boot prints its Stadium lines as on 2026-11-06.

src/starkernel/
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).
