Birthing — Kernel QEMU Acceptance Test Summary

Date: 2026-05-27 Branch: birthing Feature: Lifecycle words (BIRTH KILL START STOP USE) + ." compile-mode fix

Scope

These logs cover the kernel UEFI build (make -f Makefile.starkernel ARCH=<arch> clean qemu). All three architectures booted to ok>, ran POST, and executed capsules/init.4th successfully.

Kernel QEMU Results

Arch	Tests	Passed	Failed	Errors	BIRTH Hermes	BIRTH Artemis	."
amd64	800	734	0	0	[Hermes] Hermes Up / live	[Artemis] Artimis Up / live	PASS
aarch64	800	734	0	0	[Hermes] Hermes Up / live	[Artemis] Artimis Up / live	PASS
riscv64	800	734	0	0	[Hermes] Hermes Up / live	[Artemis] Artimis Up / live	PASS

Key Evidence (all three architectures identical)

[Hera] POST: PASSED
[Hera] Init: loading init.4th...
[Hermes] Hermes UpBIRTH: Hermes live
[Artemis] Artimis UpBIRTH: Artemis live
[Hera] Init: init.4th OK

." in compile mode now uses the (do-string) inline runtime — string bytes live inside the threaded code body, not at body_addr. The previous LIT-addr-LIT-len-TYPE approach overwrote the start of the word body with string bytes, causing a triple fault when execute_colon_word read them as DictEntry pointers.

What Changed

• src/word_source/io_words.c — ." compile mode replaced with (do-string) inline approach; (do-string) runtime word reads inline string via return-stack IP, prints, advances IP past padded block
• src/starkernel/capsule/mama_forth_words.c — BIRTH KILL START STOP USE kernel implementations; fixed caddr+1 offset bug to align with FORTH-79 S"
• src/word_source/string_words.c — S" fixed to FORTH-79 standard ( -- c-addr u )
• src/word_source/lifecycle_words_hosted.c — hosted Linux stubs (guarded #ifndef STARKERNEL)
• src/main.c — register_lifecycle_words(&vm) wired in for hosted build
• capsules/init.4th — S" Hermes" BIRTH + S" Artemis" BIRTH
• capsules/hermes/init.4th — stub: : UP ." Hermes Up" ; UP
• capsules/artemis/init.4th — stub: : UP ." Artimis Up" ; UP

Remaining Interactive Tests (require Captain Bob)

• S" Hermes" USE — switches system console to Hermes
• S" Hera" USE — switches back
• KILL + re-BIRTH a VM in the same session
