-description: Build and inspect a writable Docker demo harness from the current Homarr checkout when validating a local branch in a browser.
---

-# Homarr Local Harness
-
-Use this skill when a Homarr change needs a real production image and browser validation. Work from the repository root and keep the harness name Docker-safe, such as `feature-board`.
-
-## Set up the harness
-
-Run the TypeScript operations CLI; this workflow does not use the interactive developer TUI:
-
-```sh
-pnpm cli harness setup feature-board
-```
-
-`setup` builds the current checkout as `homarr:feature-board`, replaces the named harness container, and starts it with a persistent data volume. It enables demo mode, mock integrations, and writable demo mutations by default:
-
- `DEMO_MODE=true`
- `DEMO_READ_ONLY=false`
- `UNSAFE_ENABLE_MOCK_INTEGRATION=true`
-
-Pass repeatable environment overrides when the feature needs them:
-
-```sh
-pnpm cli harness setup feature-board \
-  --env WORKSHOP_WEB_URL=https://example.test \
-  --env FEATURE_FLAG=true
-```
-
-Use `pnpm cli harness build <name>` when only the image is needed, and `pnpm cli harness run <name>` to start an already-built image. `--port <number>` pins a host port; otherwise Docker assigns one.
-
-Always use the URL printed by the command. If the output is no longer available, query it directly:
-
-```sh
-pnpm cli harness port feature-board
-```
-
-Do not assume port `7575`; the container listens on `7575`, but the host port is dynamic by default.
-
-## Browser validation
-
-Open the printed URL with the environment's `browser-harness` tool. In this workspace, the `agent-browser` CLI is the supported browser automation fallback. Load its current workflow before invoking it:
-
-```sh
-agent-browser skills get core
-```
-
-Navigate to the exact harness URL, wait for the app to become usable, exercise the changed flow, and capture screenshots or other browser evidence. Keep browser state in a named session when the workflow needs login persistence. Report the exact URL, viewport/session used, and screenshot paths; a Docker process or HTTP health response alone is not browser acceptance.
-
-## Cleanup
-
-Stop the named container when finished:
-
-```sh
-pnpm cli harness stop feature-board
-```
-
-Stopping keeps the data volume so the same harness can be restarted. A later `setup` rebuilds the image and replaces only the container. Preserve unrelated containers, images, volumes, and working-tree changes.

-The bookmarks widget allows you to display multiple links in a single widget.
-Select one or more existing Apps directly in the widget settings; these bookmarks keep a reference to the App, so changes to its name, icon, or URL are reflected automatically.
-For links that do not need an App, add their URLs under **Custom links** instead.
-Its normal view adapts each configured layout to the available width and height: lower-priority hostnames are hidden before names or icons, and larger collections scroll instead of crushing cards.
-Advanced view shows every bookmark as a roomy card with its full title, hostname, icon, and complete description regardless of the compact layout and visibility choices.
+The bookmarks widget keeps direct URLs and Homarr Apps in one ordered list.
+Paste a URL and press Enter, paste several comma-separated or one-per-line URLs, or search for an existing App.
+URLs do not need an App record; Homarr uses the site's favicon and falls back to a link icon when it cannot load one.
+Bookmarks selected from Apps continue to use the App name, URL, icon, and description.
+
+**Adaptive** layout is the practical default: it changes between icons, compact rows, and tiles as the widget changes shape. Every compact item exposes its destination on hover, while advanced view expands items into descriptive cards.

 The board uses fixed logical units:

Thomas Camlong	240397e7ac	refactor: drop server-seeded widget clock The WidgetTimeProvider plumbed a server timestamp and the container's timezone down to useWidgetNow so clock widgets would paint a real time in the SSR HTML instead of "--:--". That traded a cosmetic first-paint win for a wrong clock: the seeded timezone is the server's, so anyone whose timezone differs from the container's saw an incorrect time for the whole hydration window. Fixing that properly needs a client-set timezone cookie read during RSC render, which is far more plumbing than the problem warrants. Revert the clock to release/v2 behaviour ("--:--" until hydration) and drop the provider, the @homarr/widgets/time export and their tests. The e2e clock assertions now wait on hydration explicitly instead of the seeded paint. Also restore the widget.beszel.getSystemStats persistence exclusion. #6289 added it deliberately to keep those large time-series payloads out of the persisted cache, and this branch had removed it with no stated rationale. Query-cache persistence and the background-refresh indicator are unchanged.	2026-08-23 09:00:34 +02:00

Thomas Camlong	a22fb60647	fix: harden widget query persistence and refresh indicator Review follow-ups on the session query cache: - Cache the per-payload size verdict and reuse a single TextEncoder. The persist subscription re-dehydrates the whole cache on every cache event, so every widget payload was being superjson-serialized several times per refresh cycle just to measure it. - Skip the size measurement on the restore path. It runs before any query is allowed to fetch and the payload was already budgeted when it was written. - Reject stored queries whose dataUpdatedAt is not a positive finite number; `undefined <= 0` is false, so those were hydrating with a NaN timestamp. - Add `stop()` and tear the persister down before `queryClient.clear()`, so the clear cannot overwrite the saved snapshot with an empty cache. - Remove every other scope's cache when a persister is created: signing out navigates away before the scope guard can react, which left the previous account's dashboard data in the tab. - Remove the entry instead of storing an empty cache. Refresh indicator: - Make it decorative instead of an aria-live region; every widget refreshes on a timer, so it made assistive technology repeat "loading" forever. Also broadens the e2e hydration-error matcher to production React's minified error codes, hoists the single WidgetTimeProvider in ClientBoard, memoizes the resolved local time zone, and drops the exports this branch made dead.	2026-08-23 09:00:33 +02:00
