dsh-file-mount: Incremental File Mounting and Deduplication on Repeated Reads

dsh-file-mount is a DeepSeek Harness plugin maintained by acefun29, which intercepts the results returned by read/write/edit tools to maintain a file line-level mounting ledger. It supplements only missing lines during repeated reads, performs incremental remounting based on line-level diffs when disk changes occur, and provides a Web-based "Mounted Files" dashboard to display coverage maps, freshness, and estimated token savings. This article introduces its working principles, installation commands, configuration options, and applicable scenarios.
