Start with room meter cards and the shared line maintenance schedule. It is the source used to decide how households compare service when heat reaches a branch at different times; it is not the decision itself. The rule only works if the source describes conditions at the warm line beneath Flint Steps.
Known: the current file counts 66 rooms with a reading before and after a maintenance turn, compared with 68 in the prior window. The map crew posts an updated card while keeping the earlier copy linked. The entries have dates and a named clerk.
Disputed: The service board reports the shared line. Residents ask for the room reading after the final branch. One side emphasizes the posted total; the other points to the lowest room cools before the shared line reaches its final branch.
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 responsible office has begun the follow-up set by the board, which sent a separate sign question to a new route review without reopening this one.
