- TLDR:Fathom is presented, a key scan in which each query decides how many bits of each key channel to read, and on real coding-agent sessions Fathom reaches the step agreement of the most accurate 136-bit scan at 92 bits.

- 标题中文:Fathom:面向卸载 KV 缓存稀疏解码的每查询读取深度
- TLDR中文:本文提出 Fathom,一种 key scan,其中每个查询决定读取每个 key 通道的比特数;在真实的 coding agent 会话中,Fathom 以 92 bit 达到最准确的 136 bit scan 的步骤一致性。
