Work in progress on StarForth-v4.0.0; not yet accepted (plan 2026-10-29-stick-5, Task 1). - zuse_genesis_marker.h: the marker's version 2 -- the proxy's key and the real Zuse's -- beside version 1. - capsule_zuse_boot.c: capsule_zuse_boot_check_key() (the identity-record half of the check) and capsule_zuse_boot_genesis_mint() (the mint half of v3's genesis) split out; v3's two callers unchanged in behaviour. - sk_v4_marker.c: the v4 boot reads version 1 as a proxy with no real Zuse, and writes version 2. - sk_v4_identity.c: no marker and a blank identity partition -> genesis: mint, read back, then the marker; the proxy logs in. A marker with a real key: no session for the proxy (the fixed screen is Task 5). - qemu_session.py: boot()/shutdown(), so a mode can boot twice; modes genesis and stick_genesis; stick_boot now expects genesis and the prompt. Logs: genesis on amd64 before the change (both boots: "no genesis on this disk", FAIL) and after (minted, then recognised: PASS). The DoE CSV of 032532 is from a run whose QEMU never started (no display; its empty log directory was removed).

/* sk_v4_marker.h -- the genesis marker, as the v4 boot reads and writes it:
|
|
* version 2, the stick's proxy Zuse and the real Zuse (docs/v4.0.0/STICK.md 6,
|
|
* 6a; plan 2026-10-29-stick-5, Task 1). On Artemis's metadata fence,
|
|
* devblock 0 from the top (blk_meta_zone_read/write), as v3's version 1.
|
|
*
|
|
* Built only with STARFORTH_V4=1 (Kconfig.kernel).
