Records the statusline scope boundary decided during triage of #2160-2164:
the statusline sources only local, read-only data (refine-existing + new-local),
never credentials or external/network APIs. #2164 (account-usage segment) is
out of scope on this boundary; #2163 (git) is in-scope but on the feature track;
#2160/2161/2162 are approved enhancements.
