Upgrade V is the largest single-day core refactor so far: orchestration, memory, and context compression move into first-class modules.

Shipped

Core

  • Shared memory bus — cross-turn facts with extractor hooks
  • Spaced-repetition decay in memory_rank / recall_relevant
  • TaskOrchestrator DAG — depends_on scheduling inside a round
  • Semantic compression — async buildMessages with summarizer callback
  • Rule stats telemetry for harness rule hits

Tools

  • decompose_goal, branch_explore, verify_contract
  • Plugin loader for external tool modules
  • Adaptive protocol suffix — intent-filtered system prompt sections
  • Orchestration tools wired for DAG edges and child provisioning

Docs and UI

  • Architecture, memory, and runtime-behavior docs updated for Upgrade V
  • Connection hardening and richer TUI/web session metrics (same release train)

Not yet
