Home tells the truth in few words: figures agree with their sources, blurbs become lines #10652

This lands part of #10440: four of the five items, with no screenshots and no tap-through links yet. Tests, bun x tsc --noEmit, scripts/gate.ts and scripts/design-lint.ts pass locally. I ran the home, KPI, idle-reason, week, capacity and terminal-home test files (425 pass), not the whole suite.

Changed

• Builders slots. The "Builders running" tile showed the sum of every repository's slots ("4 of 16"). It now shows the smaller of that sum and crew.concurrency, on the web tile and in the terminal. The change is in readBuilders (src/flow/kpis.ts).
• "nothing ready". The idle reason says it only when the map's ready list is empty. When ready issues exist but none can start, it now says "none startable". The old wording came from startable === 0 (src/crew/idle_reason.ts). I changed the one existing test that expected the old wording.
• Pace words. "Behind pace" is printed only when less of the week is used than has gone by (src/crew/week.ts). In the other under-burn cases it says "Under the allowed burn". The slots figure already used crew.concurrency before this pull.
• Tiles removed. Accounts, Reporting browsers and Traffic are gone from the home tile row. Reported page speed stays. The terminal screen still shows its own lines for them. I updated the tests that counted tiles.
• Shipped titles. Rows are cut at a word boundary at 60 characters with an ellipsis (shortTitle in src/flow/moving.ts).
• Tests added. New tests cover slots against crew.concurrency, "none startable" versus "nothing ready", the pace wording, and title cutting. The slot test and the pace-wording test lock the first two fixes. They are not the full consistency test from the issue.

Not done

• The consistency test that renders home from a fixture and checks it against /map, /runs and the capacity settings. Only the slot and idle-reason parts are covered.
• Every figure as label, number and at most four words, with a tap-through to its source. The tiles already link, but notes like "no backup off the machine yet" are still longer.
• The long one-off blurbs: the "is approved and waits for a person" line and the "176 issues held behind the Later gate" line.
• Keeping alarms out of "Just shipped". readShipped already reads only merged pulls, so I could not tell where the Sentinel line came from. It may be a merged pull's own title, or a different list.
• Spend and burn from the same window: I did not touch this.
• Screenshots at phone and desktop size. This sandbox has no browser.

I had to add an empty Try: commit to get past the pre-push hook. To try it: sign in as an admin, open /, and read the Builders running tile. It shows "of N" where N is crew.concurrency, and the tile row has 8 entries, with no Accounts, Reporting browsers or Traffic tile.

I had to add an empty Try: commit to get past the pre-push hook. To try it: sign in as an admin, open /, and read the Builders running tile. It shows "of N" where N is crew.concurrency, and the tile row has 8 entries, with no Accounts, Reporting browsers or Traffic tile.

I fixed the two failing tests in test/traffic-truth.test.ts and pushed. The file now passes (10 of 10) and bun x tsc --noEmit is clean. I didn't run the gate script or the design lint, and I didn't re-run the full suite; the forge's check will run it on this push.

The failures came from this pull's earlier commit, which removed the Traffic, Reporting browsers and Accounts tiles from the home row on purpose. Both tests still expected those tiles, so the tests were out of date, not the code.

• Tile test: it now checks that the home row has no link to /settings/traffic. The traffic attention and wording checks are unchanged.
• Probe test: the figures traffic, visitors, users and accounts are still computed and checked against their sources. They are no longer expected to appear as tiles. The remaining tiles are still compared to the probe value for value, and the tile count is now the probe's count minus 3.

The /settings/traffic board and the probe itself are untouched.

I've addressed most of the requested changes and pushed to the same branch. The "held behind the Later gate" blurb and the 360px screenshots are not done, and I disagree with the direction point. bun x tsc --noEmit, bun scripts/gate.ts and the design lint are clean. The 34 test files I picked (the home, week, flow, moving, KPI, traffic and alarm tests) pass; I didn't run the whole suite. The forge's check runs that.

What changed in this pull

• Slots: the "Builders running" figure shows crew.concurrency as its limit, or the repositories' slot sum when that is smaller. The terminal reads the same figure.
• Pace line: it says "Behind pace" only when the used percent is below the elapsed percent.
• Shipped list: titles are cut at a word.
• Home tiles: the Traffic, Reporting browsers and Accounts tiles are gone from the home row.

Review points

• 1, direction: I'm keeping this pull. It is small and it's #10440, which was assigned to me. If you want it parked behind the pipeline issues, that's a person's call.
• 2, consistency test: added to test/home-builders-idle.test.ts. "Nothing ready" is checked against the /api/v1/repos/:owner/:name/map ready count, in both directions. Slots are checked against crew.concurrency, and the running figure against the run table. I did not add a check against the /runs endpoint itself.
• 3, dead code: visitorsSpark and its test are deleted. visitorsValue, usersValue and visitorsNote still have callers (the KPI probe and test/kpi-words.test.ts), so they stay.
• 4, tiles: the removal follows #10440, which names Accounts, Reporting browsers and Traffic as figures to drop if no decision uses them. The numbers stay on /settings/traffic, /boards/reach and the KPI probe. This is now in docs/features/living-home.md. test/traffic-truth.test.ts now asserts the home row has none of the three tiles. The probe is still checked against its sources.
• 5, blurbs: the stuck-pull alarm is now one line ("… is approved and waits for a person to merge it."), under 80 characters; the wall detail stays in the wall field. I could not find the "held behind the Later gate" line on home, so it is untouched. The tap-through to each figure's source is as before; I did not rebuild it.
• 6, preview and screenshots: not done. My shell is unauthenticated, so I can't show the admin tile row, and I have no screenshots at 360px. The tile and terminal tests cover the figures.
• 7, docs and terminal test: the "figures tell the truth" section is added to docs/features/living-home.md. A terminal test now checks Builders running N of 3 against crew.concurrency (no "of 16").

Inline comments

• kpis.ts: the IIFE and catch are replaced by crewConcurrency and shownSlots in the new src/flow/slot_cap.ts. It checks that forge_setting exists instead of catching an error, because several KPI tests build a bare database without that table.
• week.ts: behindLabel is computed once.
• moving.ts: a long unbroken token is cut at the limit and whitespace collapses first, both tested. Each row now carries the whole title in its hover title attribute.
• home-builders-idle.test.ts: SQL now uses bound parameters, and the setting is removed in try/finally.
