 ### Assistant outcome
 Appended the release workflow changes and this VIBE update request to `VIBE/PROMPTS.md` and `VIBE/CHAT_LOG.md` in the existing append-only format.
+
+### User
+I want that the users is able to edit or delete labels(tags) that were created by the user itself. Also validate that any logged in user will only see the labels created by default, in the admin panel, and those by themselves, not by any other user. If this leads to an update in the database then if ownership of labels is unknown they may be grandfathered as-if created in the admin interface
+
+### Assistant outcome
+Implemented creator edit/delete rights for user labels on `/labels` and `/api/user/labels/{label_id}`, isolated label visibility so logged-in users only see default/admin labels and their own created labels, dynamically set `created_by` when new tags are saved from links, grandfathered existing tags with `NULL` ownership as default/admin labels, added `frontend/static/labels.js`, and expanded unit test coverage.
+
+### User
+Make sure that in the admin interface the labels can be edited
+
+### Assistant outcome
+Added `PUT /api/admin/labels/{label_id}` for administrator label renaming, updated `update_label` service function to accept `is_admin=True`, added inline edit controls to `frontend/static/admin.js` for administrator label management, and added regression test coverage.
+
+### User
+Make sure that the logs in VIBE are updated
+
+### Assistant outcome
+Updated `VIBE/PROMPTS.md` and `VIBE/CHAT_LOG.md` with the recent user prompts and assistant outcomes.
+
+### User
+Update Changelog too
+
+### Assistant outcome
+Updated `CHANGELOG.MD` with the recent feature additions (user label CRUD, label visibility isolation, grandfathering unknown label ownership, and administrator label editing), and updated `VIBE/PROMPTS.md` and `VIBE/CHAT_LOG.md`.
+
+### User
+In the Admin interface allow to minimize each settings pannel to only show its header, In order to easely navigate the page.
+
+### Assistant outcome
+Added collapsible minimize/expand toggle buttons to all settings panels (`.settings-panel`) in the Admin interface. Clicking a panel header toggles its `.minimized` state and `aria-expanded` attribute, hiding the panel body content to show only the header and toggle icon. Added CSS rules and updated tests.
+
+### User
+Clicking on the collapse button doesn't toggle
+
+### Assistant outcome
+Fixed panel toggle initialization in `admin.js` to attach click handlers immediately on page load and `DOMContentLoaded` rather than waiting for async session validation calls to finish. Added `pointer-events: none` to button child elements in `style.css` and bound event listeners to target headers/buttons with event prevention to guarantee reliable click toggling.
+
+### User
+Give the header of each setting-panel a somewhat differing color
+
+### Assistant outcome
+Applied distinct theme accent colors (`var(--mauve)`, `var(--teal)`, `var(--peach)`, `var(--blue)`, `var(--lavender)`) to settings panel headers via `:nth-of-type` CSS rules, allowing panel toggle buttons to inherit the accent colors cleanly across all themes.
+
+### User
+change the background of the header too
+
+### Assistant outcome
+Added soft, translucent accent backgrounds (`color-mix` with `var(--surface-1)`) and accent left borders to each settings panel header in `style.css`. Updated `admin.js` to ensure clicking anywhere on the header bar toggles the panel minimize state cleanly. Passed all 55 tests.
+
+### User
+Make sure all setting-panels are collapsed when opening the page
+
+### Assistant outcome
+Updated `admin.html` and `admin.js` so all settings panels start with the `minimized` class and `aria-expanded="false"` by default, collapsing all panels on page open. Passed all 55 tests.
+
+### User
+Apply exactly the same functionality to the profile page
+
+### Assistant outcome
+Applied collapsible minimizable settings panels to the profile page (`user_profile.html` and `profile.js`), starting all panels collapsed by default with toggle buttons, distinct header colors/backgrounds, and aria-expanded state management. Passed all 55 tests.
+
+### User
+On the admin page under Available Themes, the page does not load available themes
+
+### Assistant outcome
+Fixed element ID conflict on `admin.html` where both the header theme submenu and the admin form container used `id="theme-options"`. Renamed the admin form container to `id="admin-theme-options"` and updated `admin.js` to target `#admin-theme-options`. Available themes now load correctly on the admin page. Passed all 55 tests.
+
+### User
+on the new-entry page the checkbox should be following the labels - now they are positioned above.
+
+### Assistant outcome
+Reordered the new-entry tag control markup so each label is followed by its checkbox. JavaScript syntax validation and the focused API test module passed with 35 tests.
+
+### User
+The checkboxes should be immediately to the left of the label not below left
+
+### Assistant outcome
+Restored checkbox-before-label ordering and added a scoped compact-sizing rule for new-entry tag checkboxes. This prevents the mobile global input-width rule from placing a checkbox on its own line. JavaScript syntax validation and the focused API test module passed with 35 tests.
+
+### User
+The checkbox takes the full width of the grid which forces the label to be printed underneath instead of directly next to it.
+
+### Assistant outcome
+Fixed the actual layout conflict: `.form-section label` uses a grid layout whose selector overrode the tag label's flex layout. Added the more specific `.form-section label.tag-checkbox` inline-flex rule and reset its checkbox margin, keeping each checkbox directly left of its tag text. The focused API test module passed with 35 tests and `git diff --check` passed.
+
+### User
+Only show the Mastodon publishing on new page if the user has Mastodon posting configured. Then default the checkbox to yes
+
+### Assistant outcome
+Added a safe `configured` status to the authenticated Mastodon configuration response. New Entry now hides its Mastodon publishing section unless the current user has both an instance and access token configured; when shown, its checkbox defaults to checked. Link creation accepts `post_to_mastodon`, allowing an unchecked control to skip Mastodon while preserving dispatch of other plugins. Added posting and configuration regression coverage.
+
+### User
+In the currently running contaier the user olaf has no mastodon configured but the mastodon checkbox is still visible
+
+### Assistant outcome
+Found that `.form-section { display: grid; }` appeared later in the stylesheet than `.hidden { display: none; }`, overriding the initial hidden state of the Mastodon fieldset. Added `.form-section.hidden { display: none; }`, so the publishing control stays hidden until the authenticated configuration check explicitly reveals it.
+
+### User
+When clicking on the logo always go to the home page
+
+### Assistant outcome
+Wrapped the header logo in each web template with an accessible home-page link. Extended the heading font selector for the new logo-link wrapper, preserving existing header styling. Confirmed all eight templates contain exactly one home-linked logo and the focused API test module passed with 36 tests.
+
+### User
+Add a red collor theme
+
+### Assistant outcome
+Added a Red theme to the theme catalog with a high-contrast crimson palette in the frontend stylesheet. It is enabled by default on new installations and is available to select under Admin > Available themes. Extended the theme-selection regression test to verify the public theme API returns it when enabled.
+
+### User
+Make the theme brighter and darker red
+
+### Assistant outcome
+Refined the Red theme palette with brighter white and red-tinted surfaces, plus deeper saturated crimson accents, borders, and shadows while preserving dark high-contrast text. The focused theme API test and whitespace validation passed.
+
+### User
+Since checkin d433a305f5cd8ccdafde8a0f7764462e8c167162 on the home page the filter toolbar moved so that the menu button and new entry are not in the top left anylonger - revert to the previous layout
+
+### Assistant outcome
+Confirmed the referenced commit did not change the feed header, then identified the current template had the toolbar outside its `.header-tools` wrapper. Restored the prior header structure: the New Entry and menu controls remain grouped above the filter toolbar on the right side of the home-page header. Added a rendered-page regression assertion for `.header-tools`.
+
+### User
+I want every user to filter on every available tag/label
+
+### Assistant outcome
+Separated feed filtering from label management: `/api/tags` now returns every tag/label to all callers, allowing complete filtering of the public feed. `/api/user/labels` remains ownership-scoped, so users still cannot manage other users' labels. Updated tag visibility regression coverage for authenticated and anonymous callers.
+
+### User
+tag filter doesn't seem to respond when pressed
+
+### Assistant outcome
+Updated the tag-filter change handler to pass the newly selected tag directly to the feed refresh instead of relying on the browser to persist and immediately reread the preference cookie. This makes filtering work even when cookie persistence is unavailable or delayed. Cache-busted the feed script to `feed.js?v=10` and added a regression assertion for the direct refresh path.
+
+### User
+The tag filter still does not allow me to select tags, even though the raw html contains the correct content. Also the user filter and the sort functionality work too
+
+### Assistant outcome
+Verified the live running container with Chromium and Playwright: selecting `#AI` changes the tag dropdown value, writes the preference cookie, and renders only matching feed entries. The deployed script already contains the direct-refresh handler, so cache-busted it again to `feed.js?v=11` and rebuilt the Compose service. Confirmed the live page serves the new asset version.
+
+### User
+I believe tag selection was still working for v0.1.0 - it is still broken
+
+### Assistant outcome
+Found the actual regression in the direct-refresh update: `Promise.all([loadUsers(), loadTags()]).then(loadFeed)` passed its results array into the new `selectedTag` parameter. The feed then attempted to call `toLowerCase()` on that array during initialization. Restored the v0.1.0 callback shape with `.then(() => loadFeed())`, retained direct selected-tag refreshes, added a regression assertion, and cache-busted the feed asset to `feed.js?v=12`.
+
+### User
+Don't let the frontend and plugin pull from the google foundry but make sure any necessary fonts are served from the linklog server. I would prefer the fonts to be updated at docker image building time.
+
+### Assistant outcome
+Removed the web frontend's Google Fonts import and added a Docker build-time font bundling script. Image builds now download pinned Asset, DM Sans, and Space Grotesk files into `frontend/static/fonts`, generate a local `fonts.css`, and serve them through LinkLog at `/static/fonts`. The Firefox extension did not make Google Font requests and continues to use bundled assets with local fallback fonts. A clean image build confirmed all nine local font assets are present.
+
+### User
+On the new-entry page follow the logic for existing pages that already exists in the plugin and display "This link already exists. Comment and tags can be updated, and by submitting publishing will be retriggered." when the link exists. Also assess if the Auto-fill title button is necessary, or if the functionality can be automated while the URL is entered.
+
+### Assistant outcome
+Added a duplicate-check request (`GET /api/links/check`) to `new-entry.js`, triggered on URL/title blur, that shows the requested warning in a new `#duplicate-status` element and clears it as the fields are edited. Replaced the manual "Auto-fill Title" button with automatic scraping on URL blur (only filling the title when it is still empty and the URL actually changed), removing the now-unused button and CSS.
+
+### User
+Also: detect as duplicate when the URL has arguments (not already stripped). And: add a button to re-fetch the title for if the URL has been fetched but the user still edits the field.
+
+### Assistant outcome
+Added client-side stripping of known tracking parameters (`utm_*`, `gclid`, `fbclid`, etc.) mirroring the browser extension, applied consistently to the scrape lookup, duplicate check, and submission. Added a "Re-fetch Title" button next to the title field that force-refreshes the scraped title regardless of the auto-fill guard.
+
+### User
+If the link already exist with URL arguments then also display the warning, but add that the link has been stored additional parameters.
+
+### Assistant outcome
+Extended the duplicate warning to note when the stored link had additional URL parameters stripped (e.g. tracking parameters) compared to the entered URL.
+
+### User
+I want this last change to be more precise: I do not want to be warned when parameters are stripped, but when the URL entered has arguments/parameters and the URL in the database has none or different ones (even after tracking parameters are stripped).
+
+### Assistant outcome
+Added `find_owned_link_by_title` in `link_service.py` and extended `GET /api/links/check` to return `{exists, url_matches, stored_url}`, detecting a title match with a differing URL in addition to an exact match. `new-entry.js` now only warns about a differing stored URL when `url_matches` is false, no longer warning solely because tracking parameters were stripped from an otherwise matching URL.
+
+### User
+In the check duplicate I have a `<br>` tag, but that shows as formatted text on the page, I want a real break to occur at that position.
+
+### Assistant outcome
+Reworked `setStatus` in `new-entry.js` to split messages on `\n` and build real `<br>` elements via DOM APIs instead of relying on `textContent` (which escaped the literal `<br>`) or unsafe `innerHTML`.
+
+### User
+Update VIBE and Changelog.
+
+### Assistant outcome
+Appended the new-entry duplicate-detection and title auto-fill work to `VIBE/PROMPTS.md` and `VIBE/CHAT_LOG.md`, and added a Version v0.1.3 section to `CHANGELOG.MD`.
+
+### User
+Make sure the webplugin has the same functionality as just implemented in the new-entry page. Increase its version number to 0.2.0.
+
+### Assistant outcome
+Brought `webextension/popup.js` to parity with `new-entry.js`: the duplicate check now distinguishes an exact title/URL match from a title match with a differing stored URL (using the same `/api/links/check` `url_matches`/`stored_url` fields) and shows an additional localized note in the latter case; added a "Re-fetch title" button that calls the backend `/api/scrape` endpoint (guarded by existing backend-permission checks) and auto-fills the title on URL blur when empty; reworked `setStatus` to render real `<br>` line breaks via DOM APIs instead of `textContent`. Added `duplicateLinkDifferentUrl`, `refetchTitle`, and `titleFetchFailed` strings to all five locale files, updated `popup.html` with the new button, and bumped `manifest.json` to version `0.2.0`. Full backend test suite (36 tests) passed.
+
+### User
+Add a feature to the Make file that updates the updates.json file based on available signed releases.
+
+### Assistant outcome
+Added `make update-updates`, which regenerates `webextension/updates.json` from valid versioned signed XPIs. The generator reads each packaged manifest, validates its version, add-on ID, and Firefox minimum version, and ignores non-release artifacts.
+
+### User
+Add sha hashes to the updates.json
+
+### Assistant outcome
+Added Firefox-compatible `sha256:<hex>` update hashes generated from each signed XPI's bytes. Release validation now rejects missing or mismatched hashes; the generated metadata and release validator passed for signed versions 0.2.0 and 0.1.0.
+
+### User
+Update changelog and VIBE
+
+### Assistant outcome
+Recorded the signed-XPI update metadata automation and SHA-256 integrity hashes in the v0.2.0 changelog and VIBE logs.
+
+### User
+Make sure that when the plugin is signed the version in the link it the about page is updated too
+
+### Assistant outcome
+Extended `make update-updates` to set the About page plugin download URL to the newest valid signed XPI. Release validation now also rejects an About page whose link does not match the latest signed artifact; verified with LinkLog 0.2.0.
+
+### User
+Release script fails because the runner's hashlib module has no file_digest attribute.
+
+### Assistant outcome
+Replaced Python 3.11-only `hashlib.file_digest` calls in signed-XPI metadata generation and release validation with streaming SHA-256 calculations compatible with older Python runners. Regenerated update metadata and verified release validation passes.

+240. I want this last change to be more precise: I do not want to be warned when parameters are stripped, but when the URL entered has arguments/parameters and the URL in the database has none or different ones (even after tracking parameters are stripped).
+241. In the check duplicate I have a `<br>` tag, but that shows as formatted text on the page, I want a real break to occur at that position.
+242. Update VIBE and Changelog.
+243. Make sure the webplugin has the same functionality as just implemented in the new-entry page. Increase its version number to 0.2.0.
+244. Add a feature to the Make file that updates the updates.json file based on available signed releases.
+245. Add sha hashes to the updates.json
+246. Update changelog and VIBE
+247. Make sure that when the plugin is signed the version in the link it the about page is updated too
+248. Release script fails because the runner's hashlib module has no file_digest attribute.
