The activity overview derived completions from reading sessions that reached 99 percent, while the
dashboard's reading-goal widget counted completed reading attempts. The two disagreed on iOS, where
Home reads the widget and the Annual Goal card reads the overview: a book marked read by hand, one
finished on Kobo or KOReader, an audiobook whose last session stops short of the end, and a re-read
collapsed into its first finish were all invisible to the session heuristic.
Commit 3de365a0 already made completed attempts canonical for the web timeline, goal trajectory and
completion latency. The activity-overview route arrived later with its own session-based query and
reintroduced the divergence on the one surface the web never calls.
Drop the timezone conversion with it. endedOn is a calendar date rather than an instant, so it has
no zone to convert and AT TIME ZONE would only shift buckets across year boundaries.
