feat: парсер самосвидетельства health-ответов (handbook spec §5) ...

Панель читает расширенное тело health: identity (service/version/build/
environment/uptime|since), mode из белого списка {maintenance, readonly,
draining} — нейтральный бейдж в карточке, gauges — числа чипами.
Белый список известных полей: сырое тело не хранится и не логируется
(эндпоинт без авторизации), bool/вложенные значения в gauges отбрасываются,
неизвестный mode игнорируется (mode ≠ лайвность).

service_samples.report (JSON, NULL = нет самосвидетельства); колонка
добавляется к живым БД guarded ALTER в db.init_db (паттерн будущих
миграций). В API — report в списке сервисов и в истории проб.
Карточка «Сервисы»: v+environment+аптайм (fmtUptime), бейдж mode
(тексты i18n en/uk/ru), чипы gauges; пустые строки не рисуются.

feat: health-чекер сервисов — раздел «Сервисы» + спека health-эндпоинтов ...

Панель опрашивает health-URL внешних gnexus-сервисов (GET, параллельно,
каждые GHARD_HEALTH_INTERVAL=30с, таймаут 5с) и показывает их состояние
отдельным разделом: карточки с состоянием/latency/причиной, история
отклика за 24ч (график), retention точек 7 дней.

Прогрессивный минимум интерпретации: 2xx = up; JSON-тело со строковым
status — ok-набор → up, degraded-набор → деградация, незнакомая строка
→ вниз; не-2xx / таймаут / сеть → вниз. Контракт зафиксирован в
docs/health-endpoint-spec.md (минимум + рекомендуемое расширение checks).

- backend: tables services/service_samples, services_probe.py (волны
  проб через asyncio.gather, cap тела 64KB), api/services.py (CRUD +
  samples, мгновенный замер на POST/PATCH url), config GHARD_HEALTH_*
- frontend: страница /services, api-методы, nav «Сервисы»,
  i18n en/uk/ru

feat: settings section + i18n (en/uk/ru) for the whole UI ...

Language comes from the gnexus-auth account profile by default; Settings
now hosts a per-service override that survives logouts and profile-webhook
syncs (users table keeps profile JSON verbatim, override in a separate
column that the upsert never touches). Open mode stores the choice in
localStorage.

- backend: users table (zero-migration, IF NOT EXISTS), app/locales.py
  (normalize_locale/effective_locale), users upsert on session create and
  user.updated webhook, GET /me returns locale + locale_effective,
  new PATCH /api/v1/me (cookie-session only; 'auto'/'""' clears override)
- frontend: hand-rolled i18n mirror of gnexus-creds (locale ref, t() with
  Slavic plurals, EN fallback), full dictionaries (~130 strings), <html
  lang> + <title> tracked via watch; SettingsPage with language picker
  (Auto/en/uk/ru); ServerCard/ServerPage/StoragePage status triple and
  table columns unified into reactive computed t() lookups; fmtAgo/
  fmtUptime localized; nav/login/shell translated; default html lang en

feat: upgrade to gnexus-ui-kit 1.0, adopt Verdant color theme ...

Kit 0.4.0 → 1.0.0 (git dep pinned to master): rounded panels, softer
accents, tabs as segment switcher, page-header scan animation removed
by the kit itself. Custom overrides dropped where the kit now handles
them (48px topbar brand).

Theme: kit-verdant.css import (exports map only whitelists kit.css in
1.0 — theme file resolved through a vite alias until the kit ships
theme exports). Chart palette rebuilt for Verdant and re-validated
(L 0.48–0.67, chroma, CVD, contrast on #1E2522). Logo/favicon
recolored to the Verdant hues. allow-git=git.gnexus.space in .npmrc
for npm 12 git dependencies.

feat: network storage section — panel probes mounted shares itself ...

Backend: shares + share_samples tables, background probe loop
(os.statvfs every GHARD_SHARE_INTERVAL, 7-day retention, ok=0 when
the mount is unreachable), CRUD + samples API, instant first sample
on create/update, shares in MCP panel_overview.

Frontend: /storage page — share cards with status badge/progress/
used-free-total, 24h fill chart, add/delete via modal + confirm.
ChartLine shows a visible point while there are fewer than 3 samples.

README: CIFS/NFS mount + fstab examples, GHARD_SHARE_INTERVAL row.

feat: English UI, no-login API, logo/favicon, layout fixes ...

- UI fully translated to English (dashboard, server page, toasts, formatters)
- login removed: GHARD_ADMIN_TOKEN is optional now (unset = open API);
  agent key auth untouched; README/.env.example updated
- SVG logo + favicon (monitor with pulse, kit-style)
- reactivity: dashboard poll 5s, server 5s, history 10s
- layout: metric cards full-row flex, metric value nowrap,
  info/note 50/50 grid, topbar logo 48x48, server card max-width 420px,
  uptime on its own line, delete confirmed via GnConfirmDialog
- docker: ca-certificates for npm git dependency

feat: stage 3 — Vue web UI (dashboard, server page, charts) + docker build ...

Frontend (Vue 3 + Vite, gnexus-ui-kit, chart.js):
- login by admin token (localStorage, Bearer)
- dashboard: server cards with status, CPU/RAM/disk progress, net MB/s, note
- server page: metric cards, info (hostname/os/kernel/ips), editable note,
  history charts (1ч/6ч/24ч/7д), tabs: overview/disks/net/processes/docker
- create-server flow with one-time key display + install command

Backend: serve built SPA from panel/backend/static (assets mount + fallback)

Docker: multi-stage build (node:22 → npm ci/build → static into python image),
build context moved to repo root, .dockerignore added
