+Subject: [PATCH] fix: Respect ordering of provided ledgers
+
+Previously the _add_env_filenames function converted the filenames to a
+set. As [sets are unordered](https://docs.python.org/3/tutorial/datastructures.html#sets),
+this prevented specifying order. Some bits of the code, notably the
+default "/" route, relied on order to determine which the default ledger
+was
+
+The use of set() was first introduced in f33a63e35a1751001ac10fb992aba4e434ea7321.
+It's not entirely clear from the commit, but presumably it was intended
+to filter out duplicate items as this is a common pattern in Python. The
+type is hinted to be an Iterable[] and lists are used in other places,
+such as tests, so nothing requires using a set
+
+To make test changes as minimal as possible, this commit makes the files
+included from environment variables be ordered *first*
