` after each unit row, with
│ `` containing a div that `htmx.ajax` fills.
│
│ 3. **Click target**: `.svc-name` cell (existing role=button/tabindex). Add a caret.
│
│ Alternative worth considering: keep hx-get on the name cell and point hx-target at the sibling
│ row. But toggling-close won't clear with htmx alone, and re-opening after a poll needs JS
│ anyway. All-JS is cleaner.
│
│ Tradeoff to surface to user: while a detail is expanded, the 5-second poll keeps refreshing the
│ table (re-fetching the detail each time = 1 systemctl show + 1 journalctl per 5 seconds per open
│ unit). Alternatives: (a) re-fetch on each poll (fresh data, matches the dashboard), (b)
│ re-inject cached HTML without re-fetching (no extra load but stale), (c) pause polling while
│ expanded. My recommendation: (a) re-fetch, since the dashboard is all about live polling and the
│ cost is small. Actually, wait — let me reconsider. Every 5s per open unit: `systemctl show
│ -p...` (fast) + `journalctl -o export ... | tail` — the journal.tail call. Let me check what
│ journal.tail does — runs journalctl with unit filter. That's one journalctl spawn every 5s while
│ open. The journal tab already polls every 5s and spawns journalctl, so the system is already
│ doing this. No issue.
│
│ Should I ask the user? The system reminder says to ask for confirmation on tradeoffs. Main
│ tradeoffs:
│ - Re-fetch on poll vs cached vs pause polling.
│ - Click target: name only vs whole row.
│
│ I think these are minor. I could present the plan with my recommendations and briefly note the

│ I have all the information I need. Next, before finalizing the plan, I'll ask the user two
│ simple confirmation questions about the trade-offs:
│
│ 1. While a row is expanded, the table re-renders every 5 seconds (polling). Options: keep
│ polling and re-open + re-fetch the details (live data, recommended), or stop polling while

│ 2. Multiple rows can be expanded simultaneously, or only one at a time (classic accordion).
│

│ User's choice: re-open + re-fetch on poll, click the whole row.
│
│ Alright, let me write the plan. Files to change:
│
│ 1. **templates/services.html**
│ - Each unit becomes a pair of 2 rows:
│ - `` — existing cells. The name cell keeps the
│ `.svc-name` class but loses the hx attributes (hx-get/hx-target/hx-swap). Should
│ role/tabindex/title be moved to the `tr`? Keyboard accessibility: the row gets
│ `tabindex="0" role="button"`. Simpler approach: keep tabindex/role on the tr, and put a
│ keydown handler on the tr. Actually the existing keydown handler targets `.svc-name`
│ elements with Enter/Space. We can keep that handler and just make `.svc-name` the inner
│ span of the row. Click the row → toggle. Enter/Space on the focused name span → toggle.
│ - Name cell contents: `▸ name `? Hmm. Let me design it:
│ - ` `? Making the tr focusable +
│ the name focusable = double focus. Simplest: keep focus on the name cell (`role="button"
│ tabindex="0"`), and toggle with Enter/Space (existing handler, changed to call the
│ toggle). Row click also toggles (delegated click on tbody, ignore if the target is a
│ button or its descendant... actually, clicks on buttons will bubble. So check
│ `e.target.closest("button")` and return).
│ - `
` unit header (it's
│ already in the row above)? It's optional. Suggest removing the h3 to tighten the accordion.
│ Actually, keep the diff minimal — the h3 is redundant but harmless. Remove it. Because insid
│ … [5188 more chars]
│
│ Both decisions confirmed. Here's the plan.
│
│ ## Plan: services detail as in-row accordion
│
│ **Current behavior:** clicking a unit name fetches `/api/services/{unit}/detail` into
│ `#service-detail`, a static pane below the table (`templates/index.html:92`) — invisible until
│ you scroll.
│
│ **Key complication:** `#services` is fully re-rendered every 5s (`hx-swap="outerHTML"` polling,
│ also on action POSTs), so any in-row expanded state is wiped each cycle. The fix is JS that
│ tracks open rows and re-applies them after every swap.
│
│ ### Changes
│
│ **1. `templates/services.html`** — each unit becomes a 2-row pair:
│ ```html
│
│ ...same cells; name cell becomes...
│
│ ▸ {{ u.name }}
│
│ ...
│
│
│
│ ```
│ - Remove `hx-get`/`hx-target`/`hx-swap` from the name cell (fetch moves to JS).
│ - Caret is literal unicode `▸` (autoescape pitfall).
│
│ **2. `static/js/app.js`**
│ - New state: `const openSvc = new Set()` (unit names).
│ - Delegated `click` on `document.body`: toggle when `e.target.closest("#services tr.svc-row")`,
│ but skip if `e.target.closest("button")` (action buttons).
│ - `toggleSvcRow(row)`: on open → add to set, `row.classList.add("open")`, `detailRow.hidden =
│ false`, `htmx.ajax("GET", "/api/services/" + encodeURIComponent(unit) + "/detail", { target:
│ detailRow.querySelector(".svc-detail") })`; on close → remove from set, drop `open`, `hidden =
│ true`. `detailRow = row.nextElementSibling`.
│ - `htmx:afterSwap` handler for `#services`: after each poll/action swap, re-apply `open` + show
│ + re-fetch for every row whose unit is in `openSvc` (matches the existing journal `afterSwap`
│ pattern at app.js:138).
│ - Update the existing Enter/Space keydown handler (app.js:184) to call the toggle instead of
│ `htmx.trigger(el, "click")`.
│ - `htmx.ajax` is confirmed available in the vendored htmx 1.x.
│
│ **3. `templates/index.html`** — delete the `#service-detail` pane div (line 92).
│
│ **4. `templates/service_detail.html`** — drop the redundant `{{ unit }} ` (the name is
│ in the row above); everything else stays, so no backend changes — the endpoint already returns
│ exactly the right fragment.
│
│ **5. `static/css/style.css`**
│ - Remove `.detail-pane` rules (dead).
│ - `.svc-row { cursor: pointer; }`, `.svc-caret` (inline-block, muted, `transition: transform
│ .15s`), `.svc-row.open .svc-caret { transform: rotate(90deg); color: var(--accent); }`.
│ - `.svc-detail-row[hidden] { display: none; }`; `.svc-detail-row td { background: #12161d; }`
│ plus a hover override so the generic `tr:hover` rule (style.css:143) doesn't flash the detail
│ row.
│
│ ### Behavior summary
│ - Click any part of a row (except action buttons) → detail expands directly beneath it; click
│ again → collapses. Keyboard Enter/Space on the unit name still works.
│ - Multiple rows can be open at once.
│ - Every 5s poll / action refresh re-opens open rows and re-fetches their detail (fresh props +
│ log), per your choice.
│
│ ### Verification
│ - `uv run python -m compileall -q app` (no Python changes expected to break).
│ - `curl -s http://127.0.0.1:8501/api/services | grep -c svc-detail-row` (should equal unit
│ count) and `curl -s -o /dev/null -w "%{http_code}\n"
│ http://127.0.0.1:8501/api/services/sshd.service/detail` → 200.
│ - No server restart needed (templates auto-reload; JS/CSS served from disk) — just reload the
│ page.
│ - Manual: expand a row, wait through a poll cycle (stays open, data refreshes), run a start/stop
│ (re-opens after swap), filter the unit out and back in.

│ ```
│
│ Note: `—` inside `{{ u.enabled or "—" }}` — this is a Jinja string that gets
