Robert Allan JamesandClaude Sonnet 5 21734b1a52 Console prompt: identity/machine both sides once redirected off Hera
sk_console_user_prefix() (repl.c) previously always returned "zuse"
(or the WIREBIND-attached username) as the left side of the bracket
prefix, regardless of which VM the console was actually pointed at --
"[zuse@rajames]" after USE rajames, always showing the authenticating
superuser rather than the active identity.

Changed on Captain Bob's direct instruction: once the console is
redirected into a WIREBIND identity's own console VM
(console_get_vm_name() != "Hera"), show that same name on both sides
-- "[rajames@rajames]" -- since WIREBIND births the console VM
literally named after the identity, so the identity IS that VM, not a
separate label. At the top level (still on Hera, nothing has
redirected yet), the original zuse_session/WIREBIND-username logic is
unchanged.

An earlier, more ambitious attempt (separate identity/machine tracked
state across every console_set_vm_name() call site) regressed live to
a wrong [zuse@Artemis] prompt and was fully reverted before reaching
any acceptance run -- the landed fix needed none of that new state,
just this one function.

Verified live on all three architectures: [zuse@Hera] at the top
level and after a live WIREBIND attach (before USE), [rajames@rajames]
after USE rajames, with task 3.9's Stage D relay still firing
correctly on top of it. Zero UNKNOWN WORD, dict_hash unaffected
(display-only change).

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.
