Metric contract
One meaning for every number.
This is FragLedger's product-wide CS2 stat vocabulary. A metric is not shown as zero when its source is missing, and advanced measurements do not become available until their required demo artifact is complete.
Core ledger
Available after a complete scoreboard and round ledger is reconciled.
Advanced manifest
Requires a complete event-level demo analysis manifest.
Position artifact
Requires a separately generated position/tick artifact.
External integration
Requires the player to link the named external service.
