Reading the asset timeline

Each asset carries a timeline of events: assignment changes, lifecycle transitions and recorded activity against the thing itself. It answers "what changed on this machine, and when" as a first-class question rather than one you reconstruct from three other systems.

This is the view that pays for itself during disputes and post-incident reviews. When a user insists a machine has always behaved this way, the timeline says when it was reassigned to them and what happened to it before that. When a machine fails three months after a repair, the timeline tells you the repair happened and what it was for. When somebody asks why a laptop is in the wrong office, it usually tells you who moved it.

It is also how you keep the endpoint record and the asset record from drifting apart. An endpoint is bound to an operating-system install; rebuild the machine and the endpoint history effectively restarts. The asset outlives that. A machine that has been rebuilt twice has one asset timeline and three endpoint records, and only the timeline tells the whole story.

Read it alongside the action log rather than instead of it. The timeline is about the thing — who has it, where it is, what state it is in. The action log is about the operations the platform performed on it. Most useful diagnoses come from lining the two up against a date.

Keep the timeline honest by recording lifecycle events when they happen rather than in a periodic tidy-up. A timeline reconstructed from memory six months later is a story about what people remember, which is not the same as a record.
