Mimir v1.2.0 — Phase 2: Multi-Agent & Federation

Theme: "One memory engine, many agents, many workspaces." Q4 2026, 4 ships.

Workspace Scoping (#175)

workspace_hash column for multi-agent isolation. Agent A's memories invisible to Agent B. Scoped recall filter. Latent bug fixed: always_on/certainty were silently dropped on every recall (short SELECT lists).

Agent Identity (#176)

agent_id on entities + journal. Every entity tracks which agent wrote it. Context injection can filter by agent. Journal timeline shows agent attribution.

Cross-Workspace Federation (#177)

mimir_federate tool: export→remap workspace_hash→import between workspaces. Vault export now scopeable by workspace. .md frontmatter preserves workspace_hash + agent_id.

Access Controls (#178)

visibility column (private/workspace/public). mimir_share tool for sharing individual entities. --workspace-token CLI flag for cross-workspace auth. 33 MCP tools total.

By the numbers

  • 4 PRs merged (Week 1-11)
  • 5 new entity columns: workspace_hash, agent_id, visibility (+ journal equivalents)
  • 2 new MCP tools: mimir_federate, mimir_share

  • 31 passing Rust tests (+16 Python integration tests)
  • 8.7 MB binary
