Decide board-by-board hardware rollout: v2.2.0 (SER5 amd64) / v2.4.0 (RasPi5 aarch64) / v2.5.0 (all three)

Browse Source 
Real silicon arrives incrementally (Beelink SER5 in hand now; RasPi 5 + Milk-V
orderable around Mon 2026-08-31), so the hardware release is split per board
in hand, each an even-minor LTS point-in-time cut on the same line:

  - v2.2.0  amd64 bare metal  — Beelink SER5 (two 16GB sticks: one boots the
                                thumbdrive image, one mints a real Zuse user)
  - v2.4.0  aarch64 bare metal — Raspberry Pi 5
  - v2.5.0  all three bare     — adds Milk-V (riscv64)

Each closes only when its board's items are proven live (boot to ok>, block-
fence Zuse true, backend entropy non-deterministic), never build-only.

Records the decision in the authoritative Release Versioning Policy
(docs/lithosananke/ROADMAP.md, "Board-by-board hardware rollout, decided
2026-08-29") and re-maps G.4/G.5 in FABRIC-3.md onto the new cadence, noting
v2.0.0 was cut (tag v2.0.0).

@@ -30,6 +30,27 @@ Applied to the two planned releases: the **v2.0.0** cut (even major, so LTS) is
release; **v2.5.0** is the hardware bare-metal release that transfers v2.0.0's QEMU story to
real boards. See `FABRIC-3.md` §G for the release-gate punch lists.
**Board-by-board hardware rollout, decided 2026-08-29 (extends the above as boards come
online).** Real silicon is arriving incrementally (Beelink SER5 in hand now; RasPi 5 + Milk-V
orderable around Mon 2026-08-31), so the hardware release is split per real board in hand,
each its own even-minor cut on the same line (each `X.Y.0` here is an LTS point-in-time cut,
not a separate dev line):
- **v2.2.0 — amd64 bare metal.** Beelink SER5 (in hand). Gate: the generic GPT/FAT32
thumbdrive image (`make -f Makefile.starkernel ARCH=amd64 thumbdrive`) flashes to and boots
on the real SER5 via its real UEFI; POST + `ok>`; the amd64 **RDRAND** backend
(`rng: backend = rdrand`) serves live entropy; and a real Zuse identity is minted on a
second thumbdrive in real hardware and re-attaches. Two 16 GB sticks available: one to boot
the image, one to mint the Zuse user.
- **v2.4.0 — aarch64 bare metal.** Raspberry Pi 5 (orderable ~Mon 2026-08-31). Gate: boots
on the real board, aarch64 peripheral-RNG backend live, Zuse mint/attach on real media.
- **v2.5.0 — all three bare metal.** Adds Milk-V (riscv64) to the above; the Zkr (RNDR)
backend live. This is the full "same story on all three arches on real silicon" cut.
QEMU remains the zero-degradation reference on every line; each `X.Y.0` must reproduce the
QEMU acceptance story (`POST 1012/0/0` + `ok>`, block-fence Zuse true, backend entropy
non-deterministic) on its board before it closes.
