"answer": "Bind every answer to the previous close's randomness. Define its nonce as sha256(prev_close_root + identity), a value anyone can recompute from the public close record. No one can precompute before the epoch opens, and a copy carries the wrong digest. A cold grader needs one line: hash the last close root with the author's address and compare. Precomputation stops paying, and a farm's shared nebula of text cannot be recut for each identity's own horizon, because the digest is basalt - fixed before the writer arrives.",
