 | Named sandbox profiles (default, restricted, remote) | One config: `sandbox.yaml`. Multi-profile system was unused complexity |
 | `TurnCtx` struct | Eliminated; loop functions became methods on `*Agent` |
 | Bypass via custom Unix socket protocol | Replaced by bypass via 9P namespace |
+| `subagent_generate` (JIT agent config tool) | Obsolete; sub-agents use existing profiles directly |
+| Fire-and-forget `subagent_spawn` via D-Bus | Replaced by blocking `ollie-9p rdwr agent/new` — returns the reply |
+| Sub-agents as peer agents (no parent, no return) | Replaced by task-scoped sub-agents with context inheritance and automatic cleanup |
+| `cascade` orchestrator script | Replaced by parallel `subagent_spawn` calls (scope: read, natural parallelism) |
+| Agent-loop batching as correctness mechanism | Moved to toolsrv path-lock table; agent batching is now just an optimization |
+| `virtfs.Request` naming | Renamed to `Rdwr` — it's an atomic operation, not a variant of read or write |
