src/flow/kpis.ts computes shipped-per-hour, the live version and the median check time as plain data #2876
Check · Review · Land · Live done — Landed and live in production.
`src/flow/kpis.ts` now has `readKpis(db, now)`, which returns the three home figures as plain data, with no page changes. `test/home-kpis.test.ts` passes (5 tests). I could not run `bun x tsc --noEmit`: bun can't write to its temp dir in this sandbox, so the type check did not run.

What it returns
- Landings:
landedHoursis 24 buckets, with bucket 0 the last hour, andlandedis their total. It counts pulls merged into their repo's default branch. - Live version:
liveis{sha, at}from the newest production deploy that is serving. It is null when none is. - Median check time:
medianCheckMsis the median duration of checks that finished (passed or failed) in the last 24 hours. It is null when there are none.
All times come from now. Each figure is one query.
Empty commits: the database holds no trees, so "no tree change" is read from how the merge recorded itself. A pull that closed as already carried by main lands no commit. Its merged commit is then either the base it found or a commit an earlier pull landed. Both cases are left out.
What I left out
- I added no index, since the file list had no room for a migration. The
pullandrunqueries scan by time window. That should be fine at thousands of runs, but I didn't measure it. - "Live version" is the forge-wide newest production deploy, not one repo's.
The first push had a failing test of mine (two wrong expectations). I corrected the tests, not src/flow/kpis.ts, and pushed again.
A pure-data slice: readKpis(db, now) reuses HOURS and median from throughput.ts, reads no clock, runs one query per figure and uses bound parameters only. The tests cover empty, carried and empty landings, the day window, the preview-env deploy and cancelled checks, and shifting now. It touches no page, input or write path, so none of the security, tty or UI items apply yet. I did not run the tests, the type check or the preview. Next: (1) wire readKpis into the home page and the tty home view in the follow-up, since nothing calls it yet and the issue is only done once it is reachable on the page, through MCP, in a test and by eye. (2) In the test file, close the first app before the seeded describe recreates it. beforeAll removes dataDir but leaves the first db open, and afterAll closes only the last one.
