Start with settling cards, filter changes and household distribution notes. It is the source used to decide how residents can trace a water change to one of two filters; it is not the decision itself. The rule only works if the source describes conditions at the salt settling chamber at West Reservoir.

Known: the current file counts 68 filter runs with a source and destination mark, compared with 66 in the prior window. Alimited route trial starts with a dated sign at each affected junction. The entries have dates and a named clerk.

Disputed: The chamber records a combined run. The distribution crew needs the filter number before sending water onward. One side emphasizes the posted total; the other points to two filters share one replacement card.

Why it matters: the decision determines which residents can rely on the service and which staff must carry out the change. The file does not settle that by itself.

Next: The Year third, deep rest window 1 file remains open for its scheduled decision. The next card will keep the filter number with the distribution route.
