Sessions & Messages

Rewind conversation and workspace state, powered by a persistent Change Ledger.

Cross-session messaging for DSH: any session on the machine can list and message any other, Claude Code-style, via a local heartbeat registry and inbox.

Automatic conversation distillation: background subagent reflection + skill create/update.

Share your conversations with one click.

Branch-based message editing, reroll, retry, and a version timeline.

Deep Mnemon integration: local three-tier memory (Runtime Memory, retrievable Documents, supervised Memory Spaces).

Cross-session memory: SQLite with a human-editable Markdown mirror, background consolidation (dedup, merge, conflict resolution), and six memory tools.

`/side` persistent side sessions and `/btw` one-shot side questions, run in a temporary fork without touching main history.

Share any excerpt of a conversation.

Local-first learning mode: cross-session learning threads with per-source explanations.

Import Claude Code / Codex / ChatGPT / Cursor / Gemini / Reasonix / opencode chat histories as resumable DeepSeek Harness sessions.

Cross-instance message and event handoff between DSH instances via an interconnect server.

Cited memory over DSH's lossless session log: distilled facts carry `(sessionId, eventRange)` citations that expand back to the exact original log excerpt.

Action-state time memory: record typed states and actions, then analyze trends, anomalies, and causality.

One memory layer for every AI tool and agent: Context Bundle injection, prompt-time recall, MCP tools, and turn-end DSH thread capture.

Edit user and built-in system-prompt sections with live preview.
