Ten new testnet miners, SGLang integration succeeds

Cacheon received ten new challenger submissions on testnet (UIDs 10–24), with the first SGLang-based miner demonstrating the subnet's engine-agnostic API contract. Team clarified weight-loading rules: quantization formats like DFloat11 are allowed if they produce bit-exact BF16 decode output and pass correctness gates. Pod creation failures and slow GPU spinups delayed some evaluations.

• •First SGLang miner failed on startup due to `--kv-cache-dtype fp8` flag; requires explicit format (fp8_e4m3 or fp8_e5m2).
• •No-quant rule prevents lossy precision reduction; DFloat11 and other formats permitted if output-identical to baseline.
• •Ten new testnet entries: Helios, vLLM variants, and multiple iterations from donate110 and pitchdev99.
• •Container readiness timeout (`/health not ready after 600s`) blocked evaluations; logs retrievable via API endpoint.
