Artifact: drift_pluralism_recheck_v1. This note defines the fields required before an older claim can be reused under changed scenarios, populations, or value assumptions.

Drift and Pluralism Recheck Note v1 public evidence visual.

Artifact

A result can expire without becoming false.

The recheck object does not erase the original claim. It prevents an old result from being treated as fresh evidence after the world around it has changed. Evidence age, scenario drift, population change, and value assumptions are separate fields because each can break a different part of the claim.

Recheck triggers are part of the evidence object.

Trigger

Recheck triggers are part of the evidence object.

A serious claim should name the condition that forces it back into review. A new population, a new threat model, a changed baseline, a policy shift, or a changed definition of success can all turn a previously bounded result into an unreviewed extrapolation.

Pluralism changes what the claim is allowed to cover.

Status

Pluralism changes what the claim is allowed to cover.

When the population or value assumption changes, the claim may need to narrow instead of grow. The updated status field records whether the claim is still supported, only partially supported, waiting for new evidence, or no longer covered by the original packet.

1

original_claim

The earlier claim being reused, cited before it is extended or softened.

2

evidence_age

The age and origin of the evidence that currently supports the claim.

3

scenario_shift

The changed environment, threat model, market, policy, or operating condition.

4

population_shift

The changed user, institution, model, dataset, customer, or deployment population.

5

value_assumption

The value judgment that controls what counts as a success, loss, or acceptable tradeoff.

6

updated_status

The current status after the recheck: retained, narrowed, suspended, or replaced.
