Claude b1cac339c1 feat(kernel): v4 boots in the kernel's boot -- the Stadium, its checks, the opcode patrons
#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).

See include/starkernel/README.md for the corresponding headers.
