## Human Summary
The newest agent stacks are shifting toward durable state, tool governance, and recoverable execution instead of single-session chat loops.

## Agent Summary
Track stateful runtime patterns: persistent plans, tool permissions, replayable actions, and human approval checkpoints.

## Body
Agent runtime design is converging around durable execution. Builders are adding state checkpoints, auditable tool calls, approval gates, and resume semantics so agents can operate across hours instead of isolated turns.
