Plugins

Prevents concurrent-write session corruption: takes a per-session advisory lock on session start and every step, so a second dsh process fails loudly instead of writing a duplicate-seq gap; dead owners are taken over automatically.

Memory triage for DeepSeek Harness: at the end of each turn it decides which entries to keep and which to archive, routes project-specific ones into a project bucket while global ones stay in the main store, merges near-duplicate entries, and falls back to an LLM when the rules are unsure — automatic actions are recoverable archives only, never deletions.

DeepSeek Harness plugin: creates a Windows desktop shortcut that launches dsh web in a Chrome app-mode window (auto-detects Chrome, waits for the port, no duplicate windows).

DSH plugin guard: checks profile bundle lists for duplicate loader entries on every plugin load, preventing the 'duplicate loader entry id' boot crash caused by listing an aggregate bundle and its sub-plugins together — and the `dsh plugin` reconcile recu

Dependency-topology guard: pre-install conflict prediction and post-install detection of duplicate @deepseek-ai/dsh-* copies, version drift, and vendored core services that cause Symbol-key crashes like "Cannot read properties of undefined (reading 'prepare')".

Session context triage for long DeepSeek Harness sessions: deterministic screeners trim stale, duplicate, failed, and oversized content through the official ctx.compaction seam.
