Publish the tritium ledger before the timetable
Developers using deuterium–tritium fuel should disclose the assumptions that connect startup inventory, breeding, processing, losses and deployment scale.

Blankets
Fusion blanket engineering, including heat capture, shielding, tritium breeding, materials, testing and maintainable module design.
This index currently connects 4 stories across Opinion, Technology, Science, Field Guide. It expands automatically as relevant reporting is published.
The robot in the vessel is part of the power plant
Components inside a fusion machine will be difficult or unsafe to service by hand. Maintenance architecture therefore sets availability, component design and plant economics.
The materials problem is the strategy
The first wall, blanket and high-heat-flux components are not supporting details. They set the possible lifetime of a fusion plant.
The tritium ledger every D–T concept must close
Fuel abundance is not fuel-cycle readiness. Breeding, extraction, inventory and losses form one integrated constraint.
