-
One unit. Its own history.
The whole journey follows the same product and its record.
Who contributes or decides: Programme participant.
What changes: The unit to be identified is defined.
Illustration. It does not depict a real Traza installation or product.
-
Before the code, an accountable party.
The participant joins and describes the product.
Who contributes or decides: Participant and programme owner.
What changes: An accountable party, the description and the identification rules are linked.
Participant: Defined responsibilities and permissions.
Product: Description and declared data.
Registering information does not by itself prove that the object matches it.
-
The identity is issued.
The identifier is linked to the unit record.
Who contributes or decides: Issuer authorised by the programme.
What changes: Narrative state: issued. This does not yet imply application or activation.
Identity: Issued · not yet applied.
The signature attests issuer and data integrity. It does not prevent physical copies.
-
Applied does not mean active.
The mark is applied to the object; activation is still pending.
Who contributes or decides: Person responsible for application on the line.
What changes: Application is recorded separately from authorisation to activate.
Application: Mark applied to the object.
Activation: Pending · not yet active.
These states are a narrative proposal; they do not extend the verification engine.
-
Activation has a condition.
The programme defines who activates and what must be checked first.
Who contributes or decides: Authorised role under the programme rules.
What changes: The state changes from pending to active and the change is documented.
Narrative state: Active · change documented.
Illustrated transition. No activation date or real authorisation is invented.
-
Linked, not given the same identity.
Units, cases and pallets keep their own identifiers.
Who contributes or decides: Participant grouping the units.
What changes: Parent-child relationships are created between levels.
Pallet: Own identity; linked to the case.
Case: Own identity; linked to the unit.
Unit: Its identifier does not change when grouped.
Querying the group does not prove that each unit is physically inside.
A container may be another level with its own identity. A lookup returns the associations in the record, not a physically verified inventory.
-
Separating also leaves a record.
When items are ungrouped, the relevant relationships are closed.
Who contributes or decides: Participant receiving or ungrouping items.
What changes: The relationship is no longer active; its previous history remains.
Case-unit relationship: Closed in the story.
Unit identity: Preserved.
A historical relationship does not prove where the product is today.
-
A gap needs context.
The record is incomplete. Let us review the reason and the expected coverage.
Who contributes or decides: Participants providing events and the review team.
What changes: Received events are compared with what was expected to be recorded.
State: Event not received.
Review: Pending synchronisation, a documented exception or another reason to establish.
An event not received is a state, not a cause. A gap does not prove fraud.
Events include the contributing role, place and declared time. Without knowing expected events and coverage, an unrecorded movement cannot be inferred.
-
Four readings. Different limits.
The lookup separates the evidence; it does not give an authenticity score.
Who contributes or decides: Person looking up and comparing the product.
What changes: Available information is shown without conflating the checks.
Signature: Issuer and integrity of the signed data. It does not prevent physical copies.
Registry: Identifier found and declared status. Does not demonstrate location.
Data: Information to compare. The person checks whether it matches the product.
Signals: Patterns in the available records. No alerts does not mean no risks.
The lookup does not certify physical authenticity.
-
The same unit, with more history.
A signal helps prioritise review. It does not make an accusation by itself.
Who contributes or decides: Review or inspection role, according to the programme.
What changes: The review and its documented outcome are added to the record.
Signal: An observation that merits review.
Outcome: Documented human decision; not an automatic verdict.
Example: the outcome may confirm or correct the state. It does not modify the record.
