Settings page hosts the language switcher; profile-edit modal removed ...

The interface-language GnSelect now lives on the Settings page (Auto /
English / Українська / Русский) and applies on change, so the Edit-profile
modal — and the pencil button that opened it — are gone. The dead profile
slugs leave the dictionaries.

Web app: en/uk/ru localization, language picked from the backend ...

Tiny reactive i18n module (locale ref, t() with {param} interpolation and
ru/uk plural forms, flat per-area dictionaries, en fallback) instead of a
vue-i18n dependency. App.vue and SecretDetailPanel.vue migrate every
hardcoded string to message slugs; /me's locale_effective (settings
override -> auth account -> en) seeds the language on load, the profile
modal gains a language GnSelect (Auto/English/Українська/Русский) that
PATCHes /me and re-applies the effective locale, and <html lang> follows.

Extension: localized strings ship in the design pack, UI language from the backend

Per-service locale override: effective locale chain, PATCH /me validation ...

users.locale is now purely the per-service override chosen in settings;
the auth-derived default lives in users.profile.locale and is never
written back over the override by login or the webhook. PATCH /me
normalizes language tags (en-US -> en), accepts auto to clear, and
rejects unsupported locales with 422. UserRead gains locale_effective
(override -> profile -> en) which the web UI and the extension use as
their UI language. The validation error handler strips non-serializable
pydantic ctx.

Compact mobile secrets rows: title line plus status/chevron line in one grid card ...

Co-Authored-By: Claude Code <noreply@anthropic.com>

UX fixes: pagination ellipsis, mobile layouts, tokens table, danger-zone radius ...

- Pagination re-collapses long page runs to "1 2 3 … 22" (AppPagination, same
  look as the kit's) for secrets, audit and admin users.
- Settings metrics: grid columns; metric cards stretch to the full track and
  stack one per row on mobile.
- Danger zone gets the standard 6px border radius.
- Revealed fields: one column on mobile, long values wrap instead of pushing
  the page into horizontal scroll.
- Secrets table on mobile becomes a card list: category stacks under the
  title, purpose column drops out, thead hidden.
- API tokens list is now a full-width table (Name / Scopes / actions).

Serve extension design resources from the server as a versioned pack ...

CSS (card + popup), field-detection keyword tables and UI config now ship as
extensions/pack/ with sha256 in pack.json and a monotonic version. The backend
serves pack.json unauthenticated (no-cache) and files versioned/immutable; a
background-worker sync validates schema, ext-version compatibility and hashes,
then stores the pack atomically in chrome.storage.local — content scripts and
the popup only read storage, never fetch, and fall back to the bundled
defaults. Publish tool auto-bumps on content change and writes pack.json last.
Firefox bundle inlines pack-shared.js; release 0.2.0.

E2E (15/15): adoption, live restyle without re-release, rollback and
min-extension guards, sha-mismatch abort, offline fallback. Tests: node 25+21,
pytest 57.

Add PWA shell and a client-side biometric gate on secret reveal ...

PWA: hand-rolled service worker (public/sw.js, no build plugin) with a
precached shell, network-first navigations with a 4s timeout and an
inline offline page, and stale-while-revalidate for /assets and public
files that byte-compares in the background and replaces an entry only
when the server copy differs. API/auth/MCP/webhook traffic is never
intercepted or cached — cookie and secret responses stay out of cache
storage. manifest.webmanifest + theme-color + apple-touch-icon; icons
rasterized from the shield logo by tools/rasterize_icons.py (192/512,
any + maskable). SW registers in main.js under the same
secure-context condition the gate uses, with silent background update
ticks on visibility/online/15min.

Biometric gate (frontend/src/biometric.js): a platform-authenticator
passkey (Android fingerprints through BiometricPrompt, Touch ID,
Windows Hello) is enrolled opt-in from Settings; every reveal and
version reveal runs a fresh WebAuthn assertion with
userVerification:"required", whose clientData/authenticatorData/
signature are verified offline in the same browser against the stored
public key. The server never learns about biometrics — this is an
interface lock, not encryption. Disable requires the same proof, and
the toggle disables itself with an explanatory note on devices
without a platform authenticator.

Also fixes a pre-existing bug the verification run caught: the detail
panel's Hide button wrote `revealed.value = null` in the template,
where refs auto-unwrap, so the panel never returned to masked state.

Verified end to end with a CDP virtual authenticator: 16 checks cover
manifest/SW/offline shell/freshness/no-API-cache, enrollment, reveal
through the gate (HTTP 200), reveal blocked with no sensor, disable
refused without the sensor and allowed with it, and the disabled
toggle + note on a device without biometrics.

Detect login fields with a scoring classifier instead of heuristics ...

field-detect.js is a pure UMD module: every input becomes a descriptor
(name/id/placeholder/aria-label/label text, visibility state, type,
autocomplete token) scored against multilingual keyword tables with
anti-keywords for traps (search, newsletter, cc, otp and now repeat-
password fields). findLoginTargets pairs one username with one password
per form context, merges confirm-password pairs, and falls back to the
closest preceding input in anonymous SPA forms.

content.js reduces to DOM probing (descriptor building + scan) and the
card/interceptor flow; the manifest loads field-detect.js first.

The module is unit-tested without a browser via tools/test-field-detect.js
(16 plain-node cases over a fake tree) and verified end-to-end in Chromium
on a page mixing russian placeholders, newsletter/search/otp/cc traps and
a confirm-password signup form: three cards, correct pairs, Use fills the
right fields only.

Makefile: the per-file $(SRC) replaces the directory prerequisite (a
stale edit inside src/ never rebuilt the bundles), recipes copy with
cp --parents, and make test runs the node suite.

Render the autofill card in a closed Shadow DOM ...

The card used to be injected straight into the page: host-page CSS could
restyle it (or hide/mimic it), page JS could read the card's DOM — leaking
secret titles — and reach its buttons via querySelector on our class names.

Now it lives in a closed shadow root on a bare sized-to-zero host element:
- CSS does not cross the shadow boundary in either direction, so page styles
  can no longer repaint the card;
- the page cannot traverse into a closed root (host.shadowRoot is null), so
  secret titles and buttons are unreachable from the main world;
- src/content.css is no longer injected into page stylesheets — it is now a
  web-accessible resource, fetched once per page and injected as a <style>
  inside the shadow root (with a graceful no-styles fallback).
- while restyling the card, bring it onto the gnexus-ui-kit 1.0 palette
  (panel #16161e, left accent border, uppercase IBM Plex Mono titles) to
  match the rebuilt popup.

Verified end-to-end in real Chromium: isolation probe reports a bare empty
host, null shadowRoot, no card nodes or CSS rules reachable from the page,
no title leak under deliberately hostile page CSS (color:red !important over
all divs); clicking Use fills the form and removes the card.

Polish custom views on kit 1.0: timeline, audit chain, modals ...

- Audit: the GnEmptyState's v-else bound to the GnPagination's v-if, so the
  phantom "No audit events" block rendered alongside a populated table; move
  pagination outside the loading/rows/empty chain and gate it explicitly.
- Timeline: spell out the text fallback inside the per-item slot (a truthy
  dynamic slot always overrides GnTimeline's item.text), humanize created_at
  to local "YYYY-MM-DD HH:mm" in history and audit, pluralize the field
  count, and draw a connector rail between markers.
- Modals/toasts: drop the app-side a-show/a-hide keyframes — kit 1.0 owns
  both transitions itself; align create-modal spacing to the kit's 15px
  rhythm and add a hairline separator between modal sections.

Verified with Playwright screenshots (history, audit, create modal
open/close/reopen) on the live server; no page errors.

Release extension 0.1.1: kit 1.0 lib, shield logo icons ...

Rebuild both browsers' packages against gnexus-ui-kit 1.0 (make lib
from frontend/node_modules) and swap the generic dots mark for the
shield keyhole logo rasterized from frontend/public/logo.svg
(icon.svg + 16/32/48/128 PNG rsvg-convert). Popup verified in
chromium: settings drawer and secrets list render with no page errors.
Version bumped in extension manifest + Makefile; extensions/manifest.json
points at the 0.1.1 zips with fresh sha256/size (0.1.0 zips removed).

Import browser extension source under extensions/extension ...

Move the gnexus-creds-extension sources (Chrome/Firefox MV3) from the
separate sibling repository into extensions/extension/ so builds live
next to the packaged releases this service distributes
 (extensions/dist/ + extensions/manifest.json, untouched).

- add a reproducible `make lib` target materializing lib/ from the
  frontend's pinned gnexus-ui-kit (gitignored, like before)
- drop the playwright-only package.json/lock; system node+zip suffice
- scoped .gitignore so it cannot shadow tracked extensions/dist zips
- README (main + extension): document the in-repo build and publish flow

Rebuilt zips differ from released ones only in the three lib files
(older kit in the release); extension code itself is byte-identical.

Adopt shield keyhole logo, serve dist public assets from SPA fallback ...

gnexus-creds now has its own mark: a shield with a keyhole, drawn in the
gnexus-ui-kit language (dark tile, line-art strokes, square keyhole
terminal in the role color). Ship it as frontend/public/logo.svg, use it
in the navigation shell instead of the external gnexus.space PNG, and
register it as the SVG favicon.

The SPA fallback in main.py returned index.html for every unknown path,
so /logo.svg rendered the HTML shell instead of the image; serve real
files that exist in frontend/dist first and fall back only afterwards.
Also drop two unused imports flagged by ruff.

Update gnexus-ui-kit to 1.0.0, drop vendored GnModal, use kit tokens ...

Upgrade the git dependency to 1.0.0 (allow-git for npm 12, recorded in
frontend/.npmrc). The vendored GnModal.vue copy is no longer needed: the
kit's overlay transitions are fixed upstream via useOverlayTransition,
and the official component is API-identical. Replace the five hardcoded
palette hexes in styles.css with kit design tokens so theme swaps stay
one import away.

Also restate the form-group hint styles for .tag-input: GnTagInput
renders its hint outside .form-group, so the scoped .form-group
.input-info styles from kit 1.0 miss it and the hint was glued to the
field with no top margin.

Pin mcp<2 to avoid fastmcp import breakage ...

mcp 2.0.0 removed mcp.server.fastmcp, breaking the import in
mcp_protocol.py at startup and causing uvicorn to crash (502 on all

mcp 1.27.1 keeps the working FastMCP API.

FastAPI endpoints and surface a new Extension tab in the Vue UI with
download cards, SHA-256, and install instructions.
