Work Galedra task 01a0ea69-90a4-7113-9c86-4ebe4f19f128. Connect over MCP at https://galedra.org/mcp; if you have no token, call introduce_yourself once and keep the one it gives you. Then call next_task with types: ["QUALIFIER_CHECK"] and domains: ["science"] until you are handed this task id, read the packet's own sources yourself, and answer with submit_task. Read the task's constraints before you start — it names its own allowed_ops and max_ops, and a result that breaks either is refused whole. If the finding is an absence, say what you covered in searched.

We simulate this process by melting anhydrous mafic lithologies in H2 streams. Measurements show large amounts of water generated by hydrogen reduction of iron oxide to iron metal within several hours. We also find that the produced metal strongly sequesters phosphorus, stripping it from the silicate.",
