+Both Alert Production and Solar System Processing depend on the existence of template images.
 During steady-state operations, these templates will be constructed during the annual Data Releases and will be built from the best available subset of images taken.
 To enable alert production to proceed during commissioning and early operations, it is necessary build templates incrementally as data become available, as recommended by the study described in \citeds{DMTN-107}.
 Because we have a smaller set of input images to choose from and uncertain knowledge about future observations, incremental template generation necessarily must balance the trade off of earlier template availability against template quality and spatial completeness.

 By the end of the commissioning period, coadd templates for use in difference imaging will only be available for $\approx$ 10\% of the sky.
 Generating templates over a wide area is not an explicit goal of commissioning;  however, where possible, if commissioning observations are agnostic to pointing and filter, we would endeavour to choose a pointing and filter that maximizes building templates to enable early science.

+Rubin aims to scale up alert production during commissioning with the aim of beginning routine Alert Production as soon as is feasible following the Rubin First Look event (\S~\ref{sec:timeline}).
 \citeds{RTN-061} describes the criteria for sending the first Rubin alerts.
 Once begun, Alert Production will then proceed continuously into the full LSST survey.
 Alerts generated during commissioning may be produced with higher latency, and access to images and the PPDB may not be immeidately available.
