REPORT — the hub's System page, made readable (2026-10-10)

Before: 3 cards plus one box table with 30 columns that scrolled sideways. Release ids, cancelled TEST approvals and package counts came first. The red „Approve now (guest + host)" sat in the middle of the page. After: 4 parts, in this order:

1. Needs attention.
2. Waiting for you.
3. Boxes: one 7-column table. Each row opens in place.
4. Details: closed by default.

No sideways scroll at 1280 px or at 390 px (measured: scrollWidth == clientWidth at both widths).

Built and tested only. No deploy, no release, no box touched. It ships with the next hub release.

Baseline

• felhom.eu main @ ec5605d4 after git pull --rebase. The last hub release in hub/CHANGELOG.md is v0.145.0.
• Architecture read: 05-hub-architecture.md §5 (floors, vouched agent), 11-os-updates.md §5.7, §5.8 and §5.11 (System page, lanes, kernel approval), 08-alarm-ladder.md §6.3 (the colours).

What changed

• hub/internal/web/system_view.go (new) is the view model:
  • buildSystemPage takes all the inputs and is pure, so the fixture can feed it.
  • summariseRow makes the box mark and the plain-words reasons, from the same cell colours as before.
  • buildWaiting makes the cards, with the same gate the buttons always had: a set exists, it is not approved, and nothing is waiting.
• hub/internal/web/system.go: the handler fills systemInput. It now also reads the controller version per box (GetCustomers). It reads the candidate package list and the healthy-night count, both only to describe a card.
• hub/internal/web/templates/system.html: the new layout and its page CSS. It uses the hub's colour tokens. The nav wraps on a phone (this page's CSS only).
• Docs: 05 (a short paragraph) and 11 §5.7 (the new layout). hub/CHANGELOG.md: an „Unreleased" entry.

Where each old item went (the Baselines contract)

Old item	Now
Flash / error line	unchanged, at the top
Per box: the 30 columns, the ring button, the updates switch	Boxes: the row opens to all of them. Ring, health, controller + agent, OS updates, kernel and last night are also in the row
Approved releases (ids, packages, by, TEST)	Details
„Approve now (guest + host)"	Details, beside the releases. It now asks: „Approve the guest and host sets now, without the usual 24 h and one night?"
Cancelled approvals (last 7 days)	Details
What ring 0 runs now (counts, first seen, the wait reason)	Details. A set still being tested is also listed under Waiting for you, with the hub's reason
Approve Docker / Proxmox / kernel set	Waiting for you: one card each, when the button is allowed
Version floors, global floor, vouched agent	Details (the #version-floors link opens it)
kernel.panic, oops, crash restarts, crash guard, root files	in each box's row, and also as a table in Details
Legend („unknown" = could not read, never a guess)	under the Boxes title

Same routes and the same _csrf field on every form. Clicking to open works without JavaScript (<details>).

Tests

• go build ./... && go vet ./... && go test ./... in hub/: see the push section.
• New file system_layout_test.go. Each test below was red-proofed: I broke the code on purpose and saw the test fail.
  • Every old item is still on the page. Red: I dropped the containerd line → Boxes lacks ">containerd</dt>".
  • Every form carries _csrf and posts only to the old routes. Red: I removed _csrf from a card → form /os/approve-pve lacks the CSRF or return field.
  • Needs attention: a green box is not listed; amber and red boxes are, with reasons; all green gives one line. Red: I skipped the cells → the amber box (agent behind) is missing.
  • Waiting for you: a card per lane, the not-ready line, nothing once approved, guest/host never a card, and the empty line. Red: I dropped the wait gate → kernel not ready: cards [...].
  • Approve now is inside Details and asks first.
• Changed old assertion: system_trim_test.go now looks for >Last disk trim</dt> (it was </th>). The label moved from a table header into the box panel.

Screenshots (made-up fixture shaped like today: 4 boxes, kernel approved, Docker still testing, Tester 2 „unknown")

All are in documentation/audits/hub-system-page-2026-10-10/. They were taken with a headless Chromium in the scratchpad, from system-fixture*.html. Those pages are written by SYSTEM_PAGE_FIXTURE_OUT=<dir> go test ./internal/web/ -run TestSystemPage_WriteFixture.

• 02-390.png — the page at 390 px (phone).
• 03-1280-details-open.png — Details open.
• 04-1280-box-open.png — one box (Tester 1) open.
• 05-1280-waiting-card.png — a Proxmox set ready, as a card with its button.

Not done / notes

• Guest and host sets get no card: they approve themselves. Their urgent override („Approve now") is in Details.
• The flash after an approval still says approved <release id>. That text comes from the /os/ route, not from this page, so I left it.
• Teardown: provisioned nothing. No machine, no host, no hub change.

Questions for the operator

1. Look at the five screenshots. Is the order right (problems first, then approvals, then boxes)? OK, or what to change?
2. Tester 2 („agent older than v0.142.0") shows red for „agent behind" plus three amber reasons. Do you want an old agent as one line only, or is the full list useful?
