refactor: introduce model layer for centralized data synchronization

Add hoover model.js as a central reactive store per subsystem, replacing
per-component data fetching with a single source of truth.

- Add hoover/model.js with modelRegister, modelFetch, and WS invalidation
- Refactor websocket.js to route messages to model refresh (drop per-component
  subscribe/unsubscribe)
- Simplify component.js by removing WS subscription management
- Add refresh option to apiSubmit, deprecate refactorLoad and checkAbort
- Rewrite all pages to use getModel() instead of inline data fetching
- Bootstrap model registrations in app.js
- Add GET /api/firewall/state endpoint
- Fix restart-services.sh restart order and add service health verification
- Update hoover.md docs with model layer architecture

# Hoover — SPA Framework
Hoover is the custom reactive SPA framework used by the Vacuum Wall web UI. It provides a lightweight VDOM rendering engine, reactive state, a hash-based router, WebSocket bindings, and shared UI components. No build step is required — all code runs as ES modules served raw by nginx.

Each render root registers a render function via `render(container, fn)`. When reactive state changes, all registered render functions re-execute in a single batched microtask, producing new VNodes that are diffed against the previous tree and patched into the DOM.
### Data Flow
```
WS message → refreshByTopic(topic) → modelFetch(name) → model.data = apiFetch()
→ reactivity proxy triggers render
→ page.render(state) reads model data
```
The **model layer** is the single source of truth for subsystem data. Pages never call `apiFetch` for data loading — they call `getModel(name)` in `init()` to get a reactive model, then read `model.data`, `model.loading`, and `model.error` in `render()`.
Mutations (`ConfirmDelete`, `ActionButton`, `QuickModal`, `apiSubmit`) refresh models by name (`refresh: 'firewall'`), not by calling load functions. The model layer ensures in-flight dedup, loading flag management, and WS-driven auto-refresh.
## Bootstrap

## Model
The model layer (`model.js`) is the **central** data synchronization mechanism. Each subsystem gets one reactive model with `{ data, loading, refreshing, error }`. Hoover handles fetching, WS invalidation, loading states, and in-flight dedup.
### `modelRegister(name, definition)`
Register a subsystem model at app bootstrap.
```javascript
modelRegister('firewall', {
subsystem: 'firewall', // WS topic to listen for ('*' = all)
fetch: async (signal) => { // async fetch function
const r = await apiFetch('/api/firewall/config', { signal });
if (!r.ok) throw new Error(r.error);
return r.data;
},
defaultData: null, // optional, initial data value
});
// Parameterized example — tab-aware fetch:
modelRegister('logs', {
subsystem: '*',
fetch: async (signal, tab) => {
const url = LOG_TABS[tab || 'journal'];
const r = await apiFetch(url, { signal });
if (!r.ok) throw new Error(r.error);
return (r.data || '').split('\n').filter(l => l.length > 0);
},
});
```
| Parameter | Description |
|---|---|
| `name` | Model name (e.g., `'firewall'`, `'dnsmasq'`) |
| `definition.subsystem` | WS topic string. Use `'firewall'`, `'dnsmasq'`, etc. Use `'*'` to match all topics. |
| `definition.fetch(signal?, param?)` | Async function that fetches and returns data. Throws on error. Receives optional `AbortSignal` and optional parameter (e.g., tab key). |
| `definition.defaultData` | Optional initial data value (default: `null`) |
### `getModel(name)`
Get a reactive model by name. Returns the model object with `{ data, loading, refresh, error }` properties. Call in `init()` to access model state in `render()`.
```javascript
// In page init
init() {
return {
firewall: getModel('firewall'),
};
}
// In render
render(state) {
const guard = renderGuard(state.firewall, 'Zones', 'Firewall zones', state.firewall.data?.zones);
if (guard) return guard;
const zones = state.firewall.data?.zones || [];
// ...
}
```
### `modelFetch(name, signal?, param?)`
Trigger a fetch for the named model. In-flight dedup ensures concurrent callers get the same promise. Updates `loading`/`refreshing` flags automatically.
```javascript
// Initial load
modelFetch('firewall');
// Post-mutation refresh
const r = await apiFetch('/api/firewall/zones', { method: 'POST', body });
if (r.ok) modelFetch('firewall');
// Parameterized fetch (e.g., tab-aware logs)
modelFetch('logs', 'journal');
modelFetch('logs', 'nginx-access');
```
**Behavior:**
- If a fetch is already in progress for this model (and param), returns the existing promise (dedup).
- Sets `model.loading = true` on first fetch, `model.refreshing = true` on subsequent fetches.
- Clears `model.error` before fetch.
- On success, assigns result to `model.data`.
- On failure, stores error in `model.error`.
- Flags cleared in `finally` block.
- Does not abort in-progress fetches — other consumers may still need the data.
- The `param` argument is passed to `fetch(signal, param)` for parameterized models. Dedup key is `name: param`.
### `refreshByTopic(topic)`
Refresh all models whose subsystem topic matches. Called by `websocket.js` when a WS message arrives.
| Model `subsystem` | Topic | Match? |
|---|---|---|
| `'firewall'` | `'firewall'` | Yes |
| `'firewall'` | `'dnsmasq'` | No |
| `'*'` | `'firewall'` | Yes (always matches) |
| `'nginx'` | `'*'` | Yes (wildcard topic) |
### `collectLoadingModels(...models)`
Combine loading/refreshing/error from multiple models for composite `renderGuard` calls.
```javascript
// Pages that consume multiple models
render(state) {
const c = collectLoadingModels(state.nginx, state.acme);
const guard = renderGuard({ loading: c.loading, refreshing: c.refreshing, error: c.error },
'Proxy', 'Nginx reverse proxy');
if (guard) return guard;
// ...
}
```
Returns `{ loading, refreshing, error }` derived from the union of all passed models.

init() {
return { data: null };
return {
firewall: getModel('firewall'),

// Called on mount and when WS topic updates arrive
async load(state, abortController, entry) {
const myId = entry ? entry.requestId : 0;
state.loading = true;
try {
const res = await apiFetch('/api/firewall/status', { signal: abortController?.signal });
if (abortController?.signal.aborted || entry.requestId !== myId) return;
if (res.ok) state.data = res.data;
else state.error = res.error;
} catch (e) {
if (abortController?.signal.aborted) return;
state.error = String(e);
}
state.loading = false;
// Optional: one-time setup on mount (e.g., opening a modal dialog)
// Not used for data loading — model layer handles that
async load(state) {
// Rarely needed
},
// Called on every reactive update — return VNode(s)
render(state) {
const guard = renderGuard(state, 'Zones', 'Zone management', state.data);
const guard = renderGuard(state.firewall, 'Zones', 'Firewall zone management', state.firewall.data?.zones);
if (guard) return guard;
const zones = state.firewall.data?.zones?.available || [];
return [
PageHeader({ title: 'Zones' }),
h('div', { class: 'card' }, esc(JSON.stringify(state.data))),
zones.map(z => h('div', { class: 'card', key: z }, esc(z))),
];
},
// Optional: cleanup on unmount
onUnmount(state) {
// abort pending fetches, clear cached state
},
});
```
**Auto-injected state:** `definePage` automatically injects `loading: true`, `refreshing: false`, and `error: null` into the state object before merging with `init()`'s return value. Your `init()` only needs to define data fields:
```javascript
// Before
init() { return { items: [], loading: true, refreshing: false, error: null }; }
// After (auto-injected)
init() { return { items: [] }; }
```
Page `init()` values override defaults if explicitly set.
Pages get data from models reactive — they never call `apiFetch` in `load()`. The model layer fetches data, manages loading/error states, and triggers re-renders when data arrives.
### Page Definition Properties
| Property | Required | Description |
|---|---|---|
| `init()` | Yes | Returns initial state. Wrapped with `reactive()` by `definePage`. |
| `subscribe` | No | Array of topic strings (e.g., `['firewall']`). Use `['*']` for all. WS auto-refresh calls `load()` on topic update. |
| `load(state, abortController, entry)` | No | Async data loader. Called on mount and by WS auto-refresh. Receive an `AbortController` for cancellation. Check `entry.requestId` against captured ID to discard stale results. |
| `render(state)` | Yes | Returns VNode(s) for the page. |
| `onUnmount(state)` | No | Called when page is unmounted. Use for custom cleanup. |
| `init()` | Yes | Returns initial state object. Wrapped with `reactive()` by `definePage`. Call `getModel(name)` here to access model data. |
| `load(state)` | No | Optional one-time setup called on mount. Not used for data loading — use model layer instead. |
| `render(state)` | Yes | Returns VNode(s) for the page. Read model data from `state.<model>.data`. |
| `onUnmount(state)` | No | Called when page is unmounted. Use for custom cleanup (e.g., aborting page-local fetches). |
### Page Lifecycle
1. **Mount**: `init()` creates state → `load()` fires with fresh `AbortController` → WS subscriptions registered.
2. **Update**: Reactive state change → `render()` re-executes → VDOM diff patches DOM.
3. **WS auto-refresh**: Topic message arrives → debounced (300ms) → prior `load()` aborted → `load()` re-called with new `AbortController`.
4. **Unmount**: Prior `load()` aborted → WS subscriptions removed → `onUnmount()` called → component entry destroyed.
1. **Mount**: `init()` creates state → `load()` fires if defined → component tracked by key.
2. **Update**: Reactive state change (from model data update, navigation, etc.)`render()` re-executes → VDOM diff patches DOM.
3. **WS auto-refresh**: Topic message arrives → `refreshByTopic()``modelFetch()` for matching models → `model.data` update → reactivity triggers `render()`.
4. **Unmount**: `onUnmount()` called if defined → component entry destroyed.

### WS Auto-Refresh Flow
When a WS message arrives for a subscribed topic:
1. Debounce starts/cancels (300ms).
2. Any in-flight `load()` is aborted.
3. After debounce, `load()` is called with a new `AbortController`.
4. The `entry.requestId` pattern ensures stale async results are discarded.
When a WS message arrives for a topic:
1. `refreshByTopic(topic)` iterates registered models.
2. Matching models call `modelFetch(name)`.
3. Model fetch updates `model.data`, triggering reactivity and page re-renders.
4. In-flight dedup prevents duplicate fetches.
Pages have no awareness of WS events. The model layer handles all WS-driven refresh.
### `onMessage(topics, handler)`
Direct one-off subscription for code outside `definePage`:
```javascript
const unsub = onMessage(['firewall'], (state) => {
// handle message
const unsub = onMessage(['firewall'], (msg) => {
// handle raw message
});
// Later: unsub();
```
Handler receives the parsed WS message object.

Standardizes "action button + ConfirmDelete" in a table cell. Use for rows that need an edit action alongside a delete action.
```javascript
ActionCell({
editLabel: 'Edit',
editClick: () => editDomain({ ...d, _s: state }),
removeUrl: '/api/proxy/domains/' + enc(d.domain),
removeMessage: 'Remove proxy for ' + d.domain + '?',
removeSuccess: 'Domain removed',
removeReload: () => load(state),
removeLabel: 'Delete',
})
```
See `ActionButton(props)` and `ConfirmDelete(props)` for parameter details.
**Parameters:**
| Parameter | Description |
|---|---|
| `editLabel` | First button text |
| `editClick` | First button click handler |
| `removeUrl` | API DELETE URL |
| `removeMessage` | Confirmation prompt text |
| `removeSuccess` | Success toast message |
| `removeReload` | Reload function |
| `removeLabel` | Delete button label (default: `'Remove'`) |
| `removeBody` | Optional JSON body to send with DELETE |
| `editCls` | Override classes for edit button (default: `'btn btn-sm btn-outline'`) |
#### `MonoText(props)`
Monospace text with optional truncation. Renders as `<span class="mono-text">`.

## Versioned Imports
Static assets in `app.js` are imported with querystring version pins (e.g., `?v=4`) to invalidate browser cache when the framework changes. Page imports omit the version string since they reference the barrel export, which the server handles with appropriate caching headers.
Static assets in `app.js` are imported with querystring version pins (e.g., `?v=7`) to invalidate browser cache when the framework changes. Page imports also include version pins. The server handles caching headers; the version query string ensures browser cache invalidation.
Dev mode (`VACUUM_WALL_DEV` set) disables aggressive static asset caching.
## Conventions
- **Pages** export `definePage({ … })` as default. Each page in `webui/static/pages/`.
- **State**: `definePage` auto-injects `loading: true`, `refreshing: false`, `error: null`. `init()` only returns data fields.
- **Load function** pattern: set `loading`/`refreshing``apiFetch` with abort signal → check staleness → assign data or error → clear loading flags.
- **Render** pattern: `renderGuard` early return → data rendering. Always return VNode array or single VNode.
- **Model-first data loading**: Pages get data from `getModel(name)` in `init()`. The model layer handles fetching, loading states, error handling, and WS-driven refresh. Pages never call `apiFetch` in `load()`.
- **Render pattern**: `renderGuard` early return → data rendering. Always return VNode array or single VNode.
- **Multi-model pages**: Use `renderGuardMulti(title, subtitle, ...models)` for combined loading/error guard. `collectLoadingModels` is still exported for edge cases needing raw flags.
- **Mutation refresh**: UI components use `refresh: 'model_name'` to trigger `modelFetch()` after API mutations. Accepts single name or array.
- **Keys** on list items use unique identifiers (`item.id`), not array indices.
- **Escaping:** Use `esc()` for any user-controlled text rendered in `h()` children. Use `enc()` for URL segments.
- **Modals:** Use `formModal` + `apiSubmit` for standard CRUD operations. Use `openModal` + custom render function for non-form content.

- **Modals**: Use `formModal` + `apiSubmit` for standard CRUD operations. Use `openModal` + custom render function for non-form content.
- **Log / stream data**: Pages that fetch raw text or streams (e.g., `logs.js`) can use the model layer with a parameterized fetch. Register the model with a `fetch(signal, param)` that selects the right URL based on `param`, and call `modelFetch('logs', tabKey)`.
