One shared task brain. Clear homes for everything around it.

A direct source comparison of OS Database, Task Manager, PM Tasks, and Agent Brain. This dated projection can evolve; stable Works and exact release receipts preserve what was believed and why.

Agent Brain owns shared task truth. Project OS owns planning structure. Runtime owns session execution. Skills Hub owns capability discovery and thin adapters. Playbooks own composed procedures. The old mixed database folder is decomposed rather than promoted wholesale.
Project OSIntent, goals, repository rules, and project adoption.
Agent BrainTasks, atomic step claims, artifacts, memory, and coordination state.
Agent RuntimeSessions, tools, execution authority, and lifecycle events.

Receipts, not vibes

Agent Brain’s verifier creates isolated databases, applies three immutable migrations twice, races two workers for one step, versions artifacts, replays offline writes, and runs dry-run/apply/idempotent imports for both reviewed legacy layouts. Private path artifacts never copy; memory and timeline require explicit opt-in. Skills Hub proves its adapters route stable Brain commands, its telemetry writes only to a Skills-owned store, and Task Commander contains no raw SQL or topology snapshot.

Not yet claimed: dry-run review of a real local legacy database, consumers outside the published Skills Hub, sustained multi-host concurrency, or the value of unconsumed custom-field and graph features.
