Provenance
The signal identifies who observed what, when it happened and its geographic or temporal scope.
Contradiction
Counter-evidence travels with the claim so an agent does not mistake one clue for absolute certainty.
Expiry
An expiry time says when the datum stops supporting a decision and must be checked again.
Reversal
The change condition states the minimum new datum that would force the agent to revise its conclusion.
