test(build): acceptance boots a fresh data stick -- every run is a first boot (#92, Task 3)

Task 3 of plan 2026-10-29-stick-5, accepted in full:
- amd64, aarch64, riscv64: the proxy Zuse minted on a fresh data stick,
  PARITY:V4_POST tests=538 pass=538 fail=0, POST: PASSED, [zuse@Hera] ok>;
  dict_hash 0xfec8c47cfc6f437f on the three
- the PC stick as built, loaded high (stick_genesis): 538/538, the prompt
- make -C v4 test-32: 39 programs, 0 failures

Regressions pass. v3_keys failed once (a virtio_blk request never completed,
logs/20261108-132844) and passed on its rerun (logs/20261108-141539).
The plan's Task 3 steps ticked; FABRIC-3 XLVIII.13.

+### 13. #92, Task 3: every acceptance run is a first boot (2026-11-08)
+
+- **Built:** a v4 `qemu` boot attaches a fresh data stick and nothing else (`kernel/Makefile`:
+  `DATASTICK` on, `ARTDISK`/`ZUSEDISK` empty, unless `KERNEL_ARGS` holds `system=v3`, whose defaults
+  are unchanged); `scripts/qemu_session.py` boots the Makefile's defaults except for the modes that
+  ask for the minted pair by name, or for no drive; `scripts/nightly.sh accept stick-high` boots the
+  PC stick as built (`stick_genesis`). `.claude/CLAUDE.md` ("The disks"), `disk/README.md` (the
+  pair: tests and v3 only), `STICK.md` 11 follow.
+- **Tested first, seen to fail:** `zuse` on the old defaults -- the pair's "identity confirmed", no
+  genesis line.
+- **Accepted:** amd64, aarch64, riscv64 each mint Zuse on a fresh data stick and reach the prompt,
+  538/538; the PC stick as built, loaded high, the same; `dict_hash 0xfec8c47cfc6f437f` on the
+  three; test-32 39 programs, 0 failures. Regressions pass: `stick_zuse`, `raw_ident`, `headless`,
+  `hotplug`, the seven GPT modes, `entropy` on the three.
+- **One failure, and its rerun:** `v3_keys` failed once -- Hestia logged `virtio_blk: request never
+  completed` and the v3 boot stalled reading Zuse's marker over virtio; its rerun passed with no such
+  line. Task 3 changes no drive a v3 boot gets, so it is counted as v3's virtio path under load, not
+  a regression -- written down here, since a lost virtio request is a fault of its own (v3 goes with
+  #156).
