Follow-up to the sinceUtc bounding (commit "project index scans + bound AppInstall reads to window"): the AppInstall cutoff was computed with a fresh DateTime.UtcNow.AddDays(-days) AFTER the session window had already been queried and several aggregates had run. That second snapshot sits a few ms later than the session query's, so the AppInstall lower bound was strictly later than the session lower bound. A session included right at the window's lower boundary could then keep its row while app summaries whose StartedAt fell into the gap between the two cutoffs were dropped — undercounting AppScripts.AvgAppsPerSession and TotalUniqueApps for boundary sessions. Capture a single `now`/`windowStart` snapshot at the top of both ComputeUsageMetricsInternalAsync and ComputeTenantUsageMetricsInternalAsync and reuse it for GetSessionsByDateRangeAsync(windowStart, …) and Get(All)AppInstallSummariesAsync(windowStart). Now both bounds are identical. UsageMetricsWindowConsistencyTests pins it: it captures the start arg passed to the session repo and the cutoff passed to the app repo and asserts they are equal (and thus <=), on both the platform and tenant paths. Verified the test bites — reverting either call to a fresh UtcNow fails it. All 2546 backend tests pass. Reported-by: Codex review Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
