DeepSeek Harness Plugin: jwilson411/dsh-mutation-receipt

`jwilson411/dsh-mutation-receipt` is a function plugin for DeepSeek Harness that provides secure file operation auditing for agents. It generates append-only JSONL receipts that record the operation path, type, and the file's SHA256 hash, providing proof of operations without exposing file content. The plugin requires the host to explicitly call the `recordMutation` function and supports viewing audit logs via a CLI tool. It runs entirely locally, performs no filesystem traversal or scanning, and includes secure path validation, making it an effective tool for balancing audit requirements with data privacy.
