DeepSeek Harness Plugin `dsh-negative-ledger`: Recording Falsified Paths and Automatically Invalidating Them Upon Evidence Changes

`@akslcw/dsh-negative-ledger` is a community plugin for DeepSeek Harness (DSH), designed to persistently record an agent's "falsified paths" and prevent repeated invocation of failed commands, attempts to read missing files, or calls to unavailable APIs. This plugin is not a memory system, cache, or bug tracker; instead, it transforms failed attempts into traceable, invalidatable negative facts by binding evidence and retry conditions. Its core mechanisms include: identifying repeated attempts via fingerprints based on command or file path; offering three modes—`warn` (default, with added contextual hints), `block` (intercepts before execution), and `off`; and automatically invalidating conclusions when dependent evidence changes to allow retries. The plugin supports SQLite (multi-process/WAL) and JSONL (single-process) backends.
