David's problem: Activity heatmap was oriented with future on the right, past on left
David caught that the activity heat graph displayed the most recent month on the left edge, making the profile appear to show zero recent activity when the opposite was true.
During a live dev-server review, David spotted an orientation defect in the activity grid:
surely the heat graph should have the latest time as the rightmost part with the past to the left of that else it seems like the user has no activity in the latter months but thats cause theyre in the future
The grid was ordered chronologically left-to-right from the past, which meant the rightmost columns were future dates with no data — giving visitors the false impression that the user had gone inactive. David caught this from a screenshot and stated the correct convention: today on the right, history extending left, matching the GitHub-style activity grid expectation.
