2026-08-28 — Pivot to actor-model agentic UI

Renamed project inbox to Actor-model agentic UI — node graph is the model; task grid is one view.

  • Actor-model agentic UI — node types, spawn-on-drift, disk layout, ACTOR_AGENTIC_UI variables

  • Project inbox (renamed) — redirect stub

  • Deprecated harness aliases: PROJECT_INBOX* → ACTOR_AGENTIC_UI, ACTOR_GRAPH_EPOCHS, etc.
