The coverage system
Eight focuses.
Eight review instruments.
Different data deserves different treatment. Every focus carries its own recording contract: source rules, cadence, reviewer gate and specialised tools.

Trust is a process
Automation does the repetition.
People own the judgement.

The number, definition, period and method are checked against an archived copy.

Where source data permits, the result is recalculated with the declared specialist tool.
The public badge never overstates the achieved tier. Scheduled collection can surface changes; sensitive publication remains reviewer-gated.
