## Surface Placement

| Option | Description | Selected |
|--------|-------------|----------|
| extend route activation + re-entry into one handoff summary | preserves one visible hypothesis-level truth path | ✓ |
| invent a separate route-handoff subsystem | would fragment the operator model | |

## Relation To Existing Mechanisms

| Option | Description | Selected |
|--------|-------------|----------|
| coexist with queue, deferred-reactivation, and follow-up reintegration helpers | keeps current execution surfaces intact | ✓ |
| auto-trigger helper mutation from the new summary | widens scope too far | |

## Scope

| Option | Description | Selected |
|--------|-------------|----------|
| declarative route handoff visibility | closes the immediate gap cleanly | ✓ |
| automatic route mutation or scheduling | too wide for the immediate next milestone | |
