v0.4.0 — 2026-05-28

Major release introducing persona injection, federation, cross-CLI messaging, and typed multi-agent delegation. This release also lays the foundation for the 0.4.1 brain-agent job runtime.

Core Identity / Persona

  • Core Identity now injects directly into briefings

    • Stable cache-pinned persona prefix
    • Zero extra tokens after first turn unless persona changes

  • New /persona command

    • /persona

    cli.personaAnchor

  • /where now shows persona anchor state

  • /briefing now includes persona source stats

Memory Improvements

  • Added /memories list [query]

    • Shows citation precision
    • Detects noisy memories automatically

  • Memory cards now show:

    • citation %
    • cited / uncited counts
    • noisy flags

  • Briefing pipeline expanded to:

    • persona
    • recall
    • working context
    • task state
    • failed attempts
    • file history

Federation Stage 1 — Shared Memory

  • SQLite WAL hardening

  • workspaceTag support on memories

  • Multi-client MCP install snippets

    • Claude Code

  • SSE push deferred to 0.4.1

Major Federation Fixes

  • Fixed idle sessions disappearing
  • Fixed multiple terminals collapsing into one session
  • Fixed MCP session breakage after brain restart
  • Fixed /agents --remote --watch freezing the REPL

CLI Multi-Agent Phase 2

  • Generated typed delegation tools:

    delegate_explorer
delegate_worker
delegate_reviewer
...

  • Added route_task

  • Typed output contracts for built-in agents

  • Added agent_route_feedback memory emission

Brain-Agent Runtime Foundations (Design Pass)

Design-only groundwork for 0.4.1:

  • BrainAgent

  • MemoryJobRecord

  • MemoryBlackboardItem

  • Planned MCP tools:

    • memory_agent_status
    • memory_agent_run
    • memory_job_retry

  • Full design freeze documented in:

    • brainrouter-docs/brain-agents.md

Testing

Massive test expansion across:

  • Persona system
  • Federation stages 1–3
  • Messaging
  • Multi-agent routing
  • Output contracts
  • Parent context snapshots

Final totals:

  • 321 brain vitest
  • 23 brain integration tests
  • 717 CLI node tests

Notes

Deferred to 0.4.1:

  • SSE federation streams
  • Persona conflict detection
