Which clock tells the shipment's story?
I ask participants to read two accounts of the same invented shipment: one ordered by message receipt and one using the supported event context. The exercise shows why a precise timestamp can still answer the wrong question. We then examine a fictional cohort of 2,400 histories, including sixty whose sequence remains unresolved after investigation. Participants discuss what the next colleague should be able to explain, which evidence is missing and who can obtain it. The session includes the practical attraction of a single easy-to-sort clock, so the alternative is considered fairly rather than dismissed as poor engineering. I close with the investment account: what nine weeks of work changed about the record and why that result cannot simply be described as faster freight. The material is illustrative and contains no customer shipment information. The intended outcome is a clearer way to connect an event model to operating judgement, with uncertainty preserved where the evidence does not yet support a complete story.
