# ArchNest — Design Decisions & Page Reference

> Living reference for visual/UX conventions and what's actually built on each page.
> Apply the Global Rules consistently to any new page. The Page Notes section
> describes the **real, deployed** implementation — not a mockup. If you change a
> page's layout or data source, update its section here in the same PR.
>
> This file replaces the old `archnest-blueprint.md` (original 6-page mockup
> pitch, since deleted — superseded by the real 11-page app below) and
> `glance.md` (original Glance spec with fictional config files like
> `systems.config`/`infra.config` that were never built — also deleted). Anything
> from those files still true (color palette, typography, card style, dropdown
> menu shape) has been folded in below.

## Global Rules (apply to every page)

### Sidebar
- Expanded width: 200px. Collapsed width: 64px (icons only).
- User can manually collapse/expand via a toggle button (not just responsive breakpoints).
- Main content `margin-left` must match the sidebar width exactly.
- Bottom of sidebar: live "System Status" widget — green dot + "All Systems
  Operational" or "X Issue(s) Detected", driven by polling integration status
  (not the fictional ping-sweep config described in the old spec).

### Page Title (Top Bar)
- Color: gold `#C8A434` — not white. Use inline `style={{ color: '#C8A434' }}`
  if a Tailwind class doesn't apply.
- Font: 18px, bold, uppercase, tracking-wide.
- No border on the top bar — it blends into the page background.
- Pages with a `pageSubtitles` entry (currently only BookNest) render a larger
  28px title + subtitle line instead, and the top bar grows from 56px → 72px —
  see `TopBar.tsx`'s `pageSubtitles` map and `App.tsx`'s `topBarHeight` lookup,
  which must be kept in sync or the layout clips/gaps.

### Colors
| Role | Value |
|------|-------|
| Background (page) | `#0D0E10` |
| Background (cards) | `#141518` |
| Background (sidebar) | `#0A0B0D` |
| Border (cards) | `#1E2025` |
| Border/accent (hover/active) | `#C8A434` (gold) |
| Success | `#2ECC71` |
| Warning | `#E67E22` |
| Danger | `#E74C3C` |
| Text (primary) | `#E8E6E0` |
| Text (secondary) | `#7A7D85` |

Tailwind v4 `@theme` custom colors (`text-gold`, `bg-card`, etc.) don't always
apply reliably — fall back to inline `style={{ color: '#C8A434' }}` when a
color isn't rendering, and verify visually after changes.

### Typography
- Card titles: 10-11px, uppercase, tracking-[1.5px], secondary color, font-medium.
- Large numbers: 24-28px, bold, primary color.
- Subtitles/labels: 10-11px, secondary color.
- Body text in lists: 13px, primary color.
- Timestamps: 11px, secondary color.

### Card Style
- Border radius: 12px. Background `#141518`. Border 1px solid `#1E2025`.
- Padding: 16-24px depending on density. No shadows (flat design).
- Hover: border transitions to gold, 0.2s ease.

### Content Alignment
- All rows in a page share the same horizontal padding (`px-6` at the parent
  container level) so the hero banner, status cards, and content rows line up
  left/right.

### Animations
- Card hover: border → gold, 0.2s ease.
- Progress ring / sparkline: animate from 0 on load, ~1s.
- Progress bars: fill animation ~0.8s.

### Icons
- Lucide React, 14-18px depending on context. Gold for active/accent, secondary
  color for inactive. Gold glow on active sidebar items:
  `shadow-[0_0_6px_rgba(200,164,52,0.5)]`.
- **Gotcha**: the installed lucide-react version's TypeScript types list some
  brand/wordmark icons (`Github`, `Gitlab`, `Linkedin`, `Youtube`) that aren't
  actually exported at runtime — `tsc --noEmit` stays clean while the page
  renders blank with a runtime `SyntaxError` only visible in the Vite dev log.
  Verify icon names against the package's actual exports before importing
  anything brand-flavored.

### No Footer
- No page has a fixed footer/status bar. Don't add one unless explicitly requested.

### Target Display
- Primary design target: 16-inch / 1920px-wide screen. Don't constrain content
  width unnecessarily — design should feel spacious.

### User Avatar & Dropdown (TopBar, every page)
- 36px circle, gold border + glow, shows uploaded avatar image or initials.
- Adjacent: display name + "Administrator" role label, chevron (rotates on open).
- Dropdown menu: header (name + email) → **Profile** (`/settings?tab=profile`)
  → **Appearance** (`/settings?tab=appearance`) → **Security**
  (`/settings?tab=security`) → **Help & Support** (`/help`) → divider →
  **Sign Out** (red, danger styling). See `TopBar.tsx`.

## Page Notes (what's actually built, page by page)

All pages below consume real backend data via `src/lib/api.ts` — **zero mock
data anywhere in the app.** Where a section says "real backend data," it means
an actual SQL-backed or live-polled endpoint, not a config file or static array.

### Glance (`/`)
- Hero banner (image with radial-gradient fade mask) + KPI cards overlapping
  the bottom edge via negative margin.
- 4 status cards: **System Status** (% of integrations reachable),
  **Infrastructure** (resource count + health breakdown from
  `api.listResources()`), **Integrations** (connected/total from
  `api.listIntegrations()`), **Bookmarks** (total + favorites from
  `api.listBookmarks()`).
- Middle row (3 columns): Resource Overview (top 6 resources + status),
  Recent Activity (5 latest from `api.listEvents(5)`), problem/critical
  resources widget.
- Bottom row: Connected Integrations grid + 4 Shortcuts buttons (to Settings,
  BookNest, Infrastructure).
- No footer. Hides the hero gracefully if the banner image fails to load.
- There is **no** `systems.config`/`infra.config`/ping-sweep/fail2ban
  machinery — that was speculative spec from before the backend existed.
  Health figures are derived directly from each integration adapter's
  `testConnection()` result, polled by the existing `/api/integrations` list.

### Infrastructure (`/infrastructure`)
- Hero banner at the `App.tsx` layout level (`showHero` includes this route),
  extending behind the sticky, transparent-on-hero-routes TopBar.
- Sub-tabs: **Overview** (only enabled tab) and **Network** (disabled,
  "Coming soon" — intentional, leave alone unless asked).
- 4 status cards: Total Resources, Healthy, Warnings, Critical — from
  `api.listResources()`.
- Middle row: Resource Distribution (donut by integration type) + Node Status
  (4-col tile grid, one tile per resource — replaced an earlier world-map
  concept since a map doesn't make sense for a small/single-site setup).
- Bottom row: Integration Health list + Recent Activity (`api.listEvents(4)`).
- Card backgrounds use a `cardDim` + `cardVignette` (radial-gradient,
  `closest-side` keyword — a fixed `%` leaves a visible hard edge on straight
  sides) combo on the middle row only, per explicit visual preference; bottom
  row stays plain/regular.

### BookNest (`/booknest`)
- Hero banner reused at layout level with page-specific tuning
  (`heroPaddingTop`/`heroObjectPosition` lookup maps in `App.tsx`).
- Large 28px title + "Your Digital Library" subtitle (the one page using
  `pageSubtitles`), header grows to 72px.
- Page stats row (Links / Categories / Favorites) + "Delete All" bulk action.
- Main column: Quick Access (top 5 categories) + bookmark groups grid (4 cols,
  full CRUD with hover edit/delete/star).
- Right sidebar (spans both grid rows via `gridRow: '1 / span 2'`): Favorites,
  Recently Added (5 newest), Link Health donut, Category Breakdown donut.
- Add/edit bookmark modal supports auto-detected favicons via
  `guessServiceIconUrl()` or manual icon entry.
- All data from `api.listBookmarks()` / `api.listBookmarkCategories()` with
  real create/update/delete calls — no local-only state.

### Terminal (`/terminal`)
- Left sidebar: SSH hosts (integrations of type `ssh`), click to connect.
- Tab bar + 1/2/4-pane split layout, each pane an independent xterm instance.
- Preferences panel (theme: ArchNest Dark/Matrix/Solarized/Midnight Blue, font
  size 11-16px, font family) — stored in `localStorage`
  (`archnest-terminal-prefs`), not synced server-side.
- WebSocket to `/api/terminal`: `connect`/`input`/`resize`/`list_tmux`/`disconnect`
  messages; supports attaching to an existing tmux session or starting a new one.
- Certificate auth (OPKSSH) shells out to the system `ssh` binary under a pty
  rather than using the JS SSH client.
- Session logging to `ARCHNEST_SESSION_LOG_DIR` is backend-supported but has
  no dedicated viewer UI yet.

### Tunnels (`/tunnels`)
- List + create form for local/remote/dynamic (SOCKS5) SSH tunnels.
- Create form fields conditionally show/hide based on mode (no endpoint
  host/port fields for dynamic mode).
- Status color map: stopped `#7A7D85`, connecting `#C8A434`, retrying
  `#E0A030`, connected `#2ECC71`, error `#E74C3C`. Polls every 3s.
- Backed by `api.listTunnels()/createTunnel()/connectTunnel()/disconnectTunnel()/deleteTunnel()`.

### Files (`/files`)
- SSH host selector + breadcrumb-navigable SFTP directory browser.
- File editor modal: plain textarea, files up to 50MB (anything larger is
  download-only). Heuristic binary detection (null bytes/control chars) decides
  base64 vs. text encoding.
- Inline directory creation, rename, delete, upload, download.
- Host-to-host transfer modal: pick source file + destination host/path,
  copy-or-move toggle, live progress bar fed by `api.getTransfer(id)` polling.

### Containers (`/containers`)
- Docker host selector (integrations of type `docker`) + container list.
- Per-container state badge (running/paused/exited/dead) with context-aware
  action buttons (Start/Stop/Restart/Pause/Unpause/Remove) — buttons disable
  themselves for invalid transitions (e.g. can't pause a stopped container).
- Live CPU/memory stats polled only for running containers.
- Logs modal (configurable tail count) and an exec modal (interactive shell via
  WebSocket to `/api/docker/exec`).

### Remote Desktop (`/remote-desktop`)
- Left sidebar: hosts from integrations of type `remote_desktop`.
- Main area is a Guacamole canvas tunneled over WebSocket to `/api/guacamole`,
  proxying to the `guacd` sidecar container (RDP/VNC/Telnet).
- Requires `ARCHNEST_GUAC_CRYPT_KEY` — sessions fail without it (the backend
  warns on startup if it's missing).

### Host Metrics (`/host-metrics`)
- Left sidebar: SSH hosts. Selecting one starts a 5-second polling loop against
  `api.getHostMetrics(integrationId)`, cleared on deselect.
- Cards: CPU/Memory/Disk gauges (color thresholds: green <75%, yellow 75-90%,
  red ≥90%) + Uptime, then Network Interfaces, Processes (top 10),
  Listening Ports, Firewall Rules (UFW/iptables), Login Activity.
- Backed by 10 sequential SSH-exec collectors under `backend/src/ssh/metrics/`
  (cpu, memory, disk, uptime, network, system, processes, ports, firewall,
  login-stats) — sequential on purpose, to avoid exceeding OpenSSH's
  `MaxSessions` limit per host.

### Settings (`/settings`)
- Fixed 200px left nav, 7 sections: Profile, Appearance, Security,
  Integrations, Notifications, Data & Backup, About. URL-deep-linkable via
  `?tab=` (`useSearchParams`) — use this pattern for any future section.
- **Profile**: display name, email, avatar upload (`FileReader.readAsDataURL`
  → base64 data URL, persisted via `api.updateMe()` — this one *is* a real
  backend round-trip, unlike the rest of the page below).
- **Appearance**: accent color swatches — **local-state only, doesn't persist
  or apply anywhere** (see Known Stubs in `HANDOFF.md`).
- **Security**: password-change form + 2FA toggle — currently placeholder UI
  pending the Phase 2 auth work in `HANDOFF.md`.
- **Integrations**: one card per type (Proxmox/Docker/NetBird/Cloudflare/AWS/
  Uptime Kuma/Weather/Remote Desktop/SSH), each with type-specific fields
  (secrets masked, eye-toggle to reveal, "Test Connection" button). Real CRUD
  via `api.createIntegration()/updateIntegration()/deleteIntegration()/testIntegration()`.
- **Notifications**: toggles — placeholder, no delivery mechanism (see
  Known Stubs in `HANDOFF.md`).
- **Data & Backup**: full JSON export/import of integrations + secrets +
  bookmarks + tunnels via `backend/src/routes/data.ts` — this is the one
  endpoint that intentionally round-trips decrypted secrets, by design, for
  backup portability.
- **About**: static version/license/links info.

### Help (`/help`)
- Fully static — no backend calls. 11 guide cards (one per real page) with a
  short description and tips. Update this page whenever a new page ships.

### Login (`/login`) / Enrollment (`/enrollment`)
- `Login.tsx`: username/password form → `api.login()` → `AuthContext`.
- `Enrollment.tsx`: two-step first-run flow — (1) create the admin account via
  `api.setup()`, gated to only work while the `users` table is empty; (2)
  optional "Connect Your Services" integration onboarding grid (skippable,
  same integration form as Settings). Routed to based on
  `GET /api/system/setup-status`.

## Backend Architecture (current, not aspirational)

- `backend/` — Fastify 5 + TypeScript (ESM, `tsx` dev / `tsc -b` build),
  `better-sqlite3` for storage, deployed as its own Docker container alongside
  the frontend and a `guacd` sidecar.
- Auth: single-user-schema JWT (`@fastify/jwt`) today — see `HANDOFF.md` for
  the multi-user/SSO roadmap (Phases 2-4, not yet built).
- Integration credentials split across `integrations` (non-secret config) and
  `secrets` (AES-256-GCM-encrypted, keyed by `ARCHNEST_SECRET_KEY`) tables —
  secrets never appear in a generic "list integrations" response by
  construction, not by remembering to redact a field.
- Every integration type has an adapter in `backend/src/integrations/`
  implementing `testConnection()` (required) and `listResources()` (optional);
  `registry.ts` maps `IntegrationType` → adapter. All 9 types
  (proxmox/docker/netbird/cloudflare/aws/uptime_kuma/weather/ssh/remote_desktop)
  are real, working adapters — none are stubs anymore.
- `backend/src/ssh/` is the shared SSH transport layer powering Terminal,
  Files, Tunnels, Transfers, and Host Metrics: `connect.ts` (jump-host
  chaining, host-key verification, cert auth), `sftp.ts` (ephemeral SFTP),
  `transfer.ts` (host-to-host streamed copy/move with progress + cancel), and
  `metrics/` (the 10 collectors listed above).
- Vite dev server proxies `/api` → `http://localhost:4000`; prod routes `/api`
  to the backend container via Nginx Proxy Manager.

## Future Integration Notes
- AWS/Cloudflare/NetBird/Proxmox/Uptime Kuma adapters are real but currently
  surface basic resource inventory + health only — deeper cost/pricing/budget
  data (mentioned in the old blueprint) is not implemented and not currently
  planned; revisit only if explicitly requested.
