Proofs

A falling curve alone proves nothing. These do:

• Reproducible step 0. Every model's initial weights come from a published seed: the first 8 bytes of sha256 of its mint (lab runs: its id and generation) as an unsigned 64-bit number, folded to 63 bits. Download the repro kit at /repro-kit.tar, run python tools/repro.py <mint> and you get the same step-0 sha256 as the coin's Proofs tab (same torch version, listed in the kit).
• Hash chain. The sha256 of every checkpoint with its step and time, newest 50 per coin.
• Weights. Download the current checkpoint (bf16 safetensors + tokenizer.json + config.json). The response header X-Checkpoint-SHA256 matches the chain.
• Receipts. Every slice of compute is a receipt with its job id, lane, seconds, $ and checkpoint.
