sk_v4_mint_zuse wiped seed and rseed only when the real Zuse was minted; its
refusals and every failure after YES left them in stack memory.
Option 1 (Captain Bob, 2026-11-12: "1 is great"): the seeds are in a 64-byte
buffer the caller owns. sk_v4_mint_zuse_with(seeds) runs the mint (now a
private mint()) and then wipes the buffer, whichever way it returned -- one
place, every exit; sk_v4_mint_zuse() gives it a buffer of its own.
kernel/tests/test_sk_v4_mint.c, 17 checks: the real gpt.c on the RAM disk, the
identity code, key mint, signature checks, marker and keyboard faked; each of
the mint's eight exits run with the buffer filled with 0xEE first -- no stick,
under 64 MiB, not YES, the key mint failing, the read-back not hers, no
marker, the marker write failing, and minted. Against the mint as it was: 7
failures (every exit but success). Now: 0. Both runs in logs/20261112-181719/. Built for
amd64, aarch64, riscv64. The identity code's two (sk_v4_genesis,
sk_v4_real_zuse_arrived) follow.

The header scan (Captain Bob, 2026-11-10): 788 source files -- 351 with the
SL-1.0 header, 12 with the old name (docs/working/experiments, kept by
ruling), 31 under someone else's licence (tools/kconfig, Linux's, GPL-2.0:
kept), and 394 with none. Ruled: the SPDX form; capsules (.4th, .f18) and
proofs (.thy) left for a ruling of their own (mkcapsule's 64x16 block format,
content-addressed capsules).

as a /* */ block (C, headers, assembly, linker scripts) or # lines (scripts,
Makefiles, Kconfig; below a shebang or a coding line); tools/mkcapsule.c,
which had the copyright line, gets the SPDX line only.
Not touched: docs/working/ (archive and old campaign material, as the
ruling kept the experiments); v4/system/post_cases.c (generated by
v4/tools/mkpost.py, "do not edit" -- the generator has the header).
Comments only: the kernel builds on amd64, aarch64, riscv64; make -C v4
test-32: 39 programs, 0 failures; every changed script parses.

Asks for a stick, shows its size, writes nothing until YES; then gpt_write_one, the partition's first devblocks zeroed, a fresh Zuse minted, read back, and only then the marker's real key. Any failure before the marker: 'failed -- nothing changed'. The gate remembers the last stick it turned away as a spare, offered first by the next mint. Builds on three ISAs; not yet called.
