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.
