fix(usage): Past 24h shows the current hour - #34203
On Usage → Past 24h the newest hour never appears. At 9:52 PM the chart and the Hour breakdown both stop at "8 PM", so the last hour of work looks like it is missing.
The request window is "now minus 24 hours, to now", and the server cuts 60-minute slices from the window start. At 9:52 the slices start at :52 and each one is labelled with the hour it starts in. "8 PM" therefore means 8:52 to 9:52. The current hour's usage is counted, but under the previous hour's name, and every other label is off by the same amount.
Change
The hourly window is now the clock hour in progress plus the 23 before it, in the viewer's time zone. Each bucket is a real clock hour and the current hour is always the last one. makeWindow in packages/shared builds the window, so web, desktop and mobile all request the same buckets. The server already slices from the requested start, so it needs no change and older servers return the right buckets too.
Showing the hour in progress means the line now ends on a partial value. On web and desktop that last segment is dotted, so it does not read as a drop in usage.
Two labels used the window's end time, which is now the top of the next hour. The header range and the tooltip's "today / yesterday" take the last hour shown instead.
One consequence to judge: the Past 24h totals now cover this hour so far plus the 23 full hours before it, where they used to cover a rolling 24 hours. The day periods already count this way (7 days is today so far plus six full days).
Scope and approval
No prior issue or discussion. This is submitted as a small, focused fix for an obvious bug: the view labels its buckets as clock hours, and the current hour is missing from them. The change is confined to how the hourly window is requested and how its last point is drawn. It does change what the Past 24h total covers, as described above.
Verification
Checked in a dev server against real provider history. The browser ran in UTC, so the labels are UTC.
Before, at 06:09: the chart ends at 5 AM and there is no 6 AM point.
After, at 06:11: the chart ends at 6 AM and the hour in progress is dotted.
Also observed after the change:
The Hour breakdown lists 6 AM (so far) above a full 5 AM. Before, its newest row was "5 AM" for 5:09 to 6:09.
The model detail dialog's hourly chart ends the same way. The 7-day chart is unchanged.
Refresh within the same hour refetches, and the in-progress hour grows.
The existing makeWindow test asserted the minute-aligned bounds. It now asserts clock-hour bounds in a half-hour zone (Asia/Kolkata) and fails on main.
Not checked: mobile on a device. It shares the window code, and its bar chart has no in-progress marker.

The hourly window ran from now minus 24 hours to now, and the server
slices hours from the window start. At 9:52 the buckets began at :52 and
were labelled by the hour they started in, so the newest label was
always the previous hour.
Request the clock hour in progress plus the 23 before it, in the
viewer's time zone, so each bucket is a clock hour. The web chart draws
the segment into the hour in progress dotted.

Macroscope's review found this PR approvable — The Past 24h usage view now includes the current clock hour and distinguishes its unfinished chart segment with a dotted line. The change is limited to reporting boundaries and presentation, without changing charges or stored usage.

Walkthrough
Hourly usage windows now span the current hour in the viewer’s time zone and the preceding 23 hours. Hourly chart tooltips use the last displayed period as their reference.

Summary
Hour-aligned usage windows packages/shared/src/usageFormat.ts, packages/shared/src/usageFormat.test.ts, apps/web/src/components/usage/UsagePage.tsx
Hourly windows now use viewer-local hour boundaries. The test checks a 24-hour window in Asia/Kolkata, and the hourly label uses the last enumerated hour.
Past 24h now covers the current clock hour plus the 23 before it. In Lord Howe, Australia, the hourly buckets can be half an hour off for a day after each daylight-saving change. This is a documented, accepted limitation affecting one zone, so merge-readiness risk is low.

Explanation
The description follows the template sections: Problem, Change, Scope, and Verification. The Problem section states the expected behavior and the observed bug. The Change section explains the window and label fixes and the cross-platform effect. The Scope section explains why no issue is linked and states that the change is a bug fix, not a feature. The Verification section gives concrete before/after checks, screenshots, and a list of unchecked items, including mobile. The description also notes the Past 24h total behavior change. The Scope section does not link an issue, but it gives the reason, as the template allows for small obvious fixes.

Review comments at @packages/shared/src/usageFormat.ts:
- Around line 277-278: The usage chart’s hour buckets can misalign with local
clock-hour boundaries during half-hour DST transitions. Update the bucket
contract around `hourStartMs` and `sinceTime` so client and server consistently
use transition-aware boundaries and earlier buckets remain aligned to clock
hours; do not address this by changing labels alone.

The dotted final segment changes how the chart looks beyond the label
fix, so it is left for a separate decision.
