Do I have to keep HTI-1 source attributes updated, and how often?

Answer.
Yes — the source attributes must reflect the DSI as it currently performs, so when the model, its data, or its validated performance changes, the attributes must be updated; HTI-1 frames this as ongoing rather than one-time, tied to the intervention's lifecycle. A recurring measurement helps you detect when an update is due. Planisphere's re-run cadence produces a drift delta that flags performance change; it informs when attributes need refreshing, it does not edit the attributes for you.
