Match confidence	Description	Recommended handling
High confidence match	Multiple key identifiers match correctly.	Process the message normally and link it to the existing transaction lifecycle.
Medium confidence match	Some strong identifiers match, but not all fields are available.	Process according to internal rules and flag for monitoring if needed.
Low confidence match	Only weak or partial identifiers match.	Store and route to reconciliation or exception handling before applying sensitive impact.
No match	No reliable related transaction was found.	Store as unmatched and process according to reconciliation or exception-handling rules.
Conflicting match	Some fields match but others conflict.	Treat as unreliable and route to exception handling.
