Provenance

Token composition is modeled as creation of new immutable values, with ancestry stored on the result and source tokens marked as appropriate. Merge and split metadata includes:

Field	Meaning
_mergedFrom	IDs of source tokens used to create a merged token.
_mergedAt	Timestamp recorded for the merge.
_mergedInto	ID of a token that superseded this token in a merge.
_splitFrom	ID of the token from which a split token came.
_splitInto	IDs of resulting split tokens.
_splitIndex and _splitAt	Position and timestamp for a split result.

These fields describe lineage; they do not by themselves enforce ownership, scarcity, or legality. A game that needs those guarantees must validate the operation through actions and policies. Provenance remains useful for audit views, replay inspection, and deriving relationships between immutable values.
