fix: editable decrypt + windows realtime wake (v0.7.1)

Edit message decrypt: - handleUpdate in useConversationMessages now refetches the canonical row via REST after a realtime UPDATE instead of trusting the realtime payload's bytea encoding. Same pattern as handleInsert — base64 vs `\x…` hex serialisation varies across supabase/postgrest versions and was silently producing undecryptable ciphertext for edited messages on the receiver side Windows WebView2 background throttling: - ConversationsContext, useFriendships and useConversationMessages now listen for visibilitychange / focus / online events and trigger both a fresh REST refresh and a best-effort channel.subscribe() on wake. WebView2 aggressively throttles background WebSockets and was dropping realtime events entirely while the window was minimised, so new messages and friend acceptances only surfaced after a manual reload Bump tauri version 0.7.0 -> 0.7.1
feat: audio devices + fullscreen + banner cleanup (v0.7.0)

 # Handoff: ChatApp — Clean Rail Redesign + Discord-Style Call UI
 ## Overview
 This package contains the full design spec for redesigning the existing ChatApp (Netralax) interface around a **Clean Rail** layout aesthetic, plus a complete **Discord-style call system** (incoming call, in-call dock, picture-in-picture, fullscreen cinema mode).
 The redesign covers:
 1. The main chat interface (icon-rail sidebar + chat list + conversation area) in both **light** and **dark** mode.
 2. The call UX: incoming call overlay → active call docked above the chat (so users can keep typing while on a call) → fullscreen cinema mode → minimizable PiP bubble.
 ## About the Design Files
 The files in this bundle are **design references created in HTML/React/CSS** — prototypes showing the intended look, layout, and behavior. They are **not production code** to copy verbatim.
 Your task is to **recreate these designs inside the existing ChatApp codebase**, using its established patterns (existing React components, styling conventions, state management, icon library, etc.). If some tokens or helper components don't exist yet in the codebase, add them but keep them aligned with what's already there.
 The design files are organized as:
 - `ChatApp Redesign.html` — entry HTML that boots the prototype
 - `components/app.jsx` — main layout (rail + chat list + chat area, plus call state machine)
 - `components/call.jsx` — all call UI components (IncomingCallScreen, ActiveCallScreen, ParticipantTile, CallControls, PipCall)
 - `components/icons.jsx` — SVG icon set used
 - `components/data.jsx` — dummy chat/message data
 - `styles/base.css` — shared base tokens + layout primitives
 - `styles/variants.css` — `variant-clean` light + dark token definitions (this is the look you're targeting)
 - `styles/rail.css` — rail-layout specifics
 - `styles/call.css` — **all call UI styles** (the most important file for the call feature)
 - `screenshots/` — reference images of each state
 ## Fidelity
 **High-fidelity.** Exact colors, radii, spacing, typography and motion are specified. Recreate pixel-perfectly using the codebase's existing component library — but prefer the codebase's primitives over duplicating the prototype's raw CSS where equivalents exist.
 ---
 ## Design Tokens (Clean Rail)
 ### Colors — Light mode (`.variant-clean`)
 ```
 --bg:        #fafaf9   (app background)
 --bg-2:      #f4f4f2   (secondary surfaces, hover, search input)

 --fg:        #0a0a0f   (primary text)
 --fg-muted:  #737380   (secondary text, icons)
 --line:      rgba(10,10,15,0.08)  (dividers, borders)
 --accent:    #4F46E5   (indigo — primary actions, active states, my-bubble)
 --accent-fg: #ffffff
 ```
 ### Colors — Dark mode (`.variant-clean.dark`)
 ```

 E2EE indicator (light):   #16a34a  (dark: #4ade80)
 ```
 ### Avatar color swatches (assigned per chat)

 teal:    bg #99f6e4 / fg #134e4a   (dark: #134e4a / #99f6e4)
 ```
 ### Typography
 - Family: `'Inter', system-ui, sans-serif` — Inter is the base. Display/headline use `'Outfit'` (participant name in IncomingCall).
 - Scale:
  - Chat title / participant name large: 24px / 700
  - Primary labels, chat name: 14–15px / 600
  - Body (bubbles, messages): 14px / 400–500
  - Meta, timestamps, presence: 11–12px / 400–500
  - Rail tooltips, badges: 10–11px / 500–600
  - Uppercase eyebrow (e.g. "EINGEHENDER ANRUF"): 12px / 600 / letter-spacing 0.12em
 ### Spacing
 - Container padding: 16px (call-stage), 14–20px (topbars, composer)
 - Tile gap in grid: 8–10px
 - Control-button row gap: 8–10px
 - Border radius scale: 4 (small), 8 (tiles/badges), 10 (buttons), 14 (cards, large buttons), 18 (bubbles, bottom-fs controls), 24 (modal/card)
 ### Shadows
 - Elevated card light: `0 20px 60px rgba(0,0,0,0.1)`
 - Elevated card dark:  `0 20px 60px rgba(0,0,0,0.5)`
 - Accent button:       `0 4px 14px rgba(22,163,74,0.3)` (green accept) / same pattern for accent
 - PiP glow:            `0 12px 40px rgba(0,0,0,0.2), 0 0 0 3px rgba(79,70,229,0.15)`
 ### Motion
 - Standard UI transition: `all 0.15s`
 - Pulse ring (incoming call): `2s ease-out infinite`, scale 0.85→1.25, opacity 0.6→0
 - Audio pulse (speaking ring): `1.3s ease-out infinite`, scale 1→1.3
 - Live dot: `1.5s ease-in-out infinite`, opacity 1↔0.4
 - PiP entrance: `slideInCall 0.4s cubic-bezier(0.22,1,0.36,1)`
 - Fullscreen hint fade: 3.5s total (0–15% fade in, 75–100% fade out)
 ---
 ## Screens / Views
 ### 1. Main Chat — Clean Rail Layout
 **Structure (left → right):**
 - **Icon Rail** (72px wide): brand logo at top, tab buttons (Chats / Friends / Admin), spacer, Settings + theme-toggle at bottom. Active tab shows a vertical pill indicator on the left edge.
 - **Chat List** (280px wide): header with title + "new chat" icon, search input, list of `ChatItem`s (avatar + name + time + preview, optional unread dot), `rail-user` footer showing own profile + quick mute/settings.
 - **Chat Area** (flex, fills rest): chat header (counterpart avatar + name + presence/handle + search/voice/video buttons), messages scroll area, composer at bottom.
 **Chat header actions (right side):** search icon, phone icon, video icon. Phone triggers voice call (`callScreen → 'active'`, `callState.video = false`), Video triggers video call (`callState.video = true`).
 **Message bubbles:**
 - Mine (outgoing): filled accent bg, white text, radius `18px 18px 4px 18px`.
 - Theirs (incoming): transparent bg, 1px line border, fg text, radius `18px 18px 18px 4px`.
 - Avatars appear only on the **last message of a run** from that sender.
 - Reactions: pill row below bubble, `.mine` = filled accent.
 - System events ("Kaiwandi hat einen Anruf gestartet — Anruf beitreten"): centered `event-pill`, muted bg, muted fg, 11px.
 **Composer:** plus button (attach), rounded input bar with inline emoji + mic icons, send button.
 ---
 ### 2. Incoming Call Overlay
 Full-bleed overlay replacing the chat area (takes over `.chat-area` space), radial-gradient background tinted with accent.
 Centered card (420px wide):
 - Eyebrow "EINGEHENDER ANRUF" (uppercase, 12px, tracked)
 - Large avatar (96px) with **two pulsing rings** (staggered 1s)
 - Caller name (24px / 700 / Outfit)
 - Subtitle row: lock icon + "E2E verschlüsselt · Voice Call"
 - Two side-by-side action buttons:
  - **Ablehnen**: transparent, red border/text, hover = 8% red bg
  - **Annehmen**: green #16a34a, white, shadow
 ### 3. Active Call — Docked (Default)
 **CRITICAL layout decision:** The active call does NOT take over the chat area. Instead it renders as a **dock above the messages**, taking roughly 50% of the chat-area height (min 280px, max 420px). The chat header is **hidden** while the dock is active (redundant — call topbar shows the channel name). Messages + composer remain fully visible and usable below, so users can keep chatting during the call. This is the Discord desktop pattern.
 **Dock content:**
 - **Call topbar**: left side shows group icon + "Die Squad" + duration (tabular-nums), with E2E verschlüsselt below in success-green. Right side has 3 mode toggles: Grid / Focus / Fullscreen.
 - **Call stage**: fills the remaining space, renders either:
  - **Grid**: CSS grid, 2×2 for 4 people, 3×2 for 5–6, 1fr 1fr for 2.
  - **Focus**: main speaker tile takes most height, bottom strip with 110px-tall smaller tiles for others.
  - **Fullscreen**: switches to `mode === 'fullscreen'` — see screen 4.
 - **Call controls bar** at the bottom of the dock: Mic, Video, Screen-share, Participants, **Hangup** (wider, red). Compact 36px buttons when docked.
 ### 4. Active Call — Fullscreen Cinema Mode
 When mode = `fullscreen`:
 - Entire call-dock container becomes absolute-positioned and takes over everything below the window bar (chat list still visible on the left).
 - The **call topbar is hidden** entirely.
 - Main speaker fills the whole frame, no border/radius.
 - Participants strip moves to a **floating column in the bottom-right** (`.fs-strip`): 180px wide, 100px tall tiles, glass-blurred bg.
 - **Call controls bar floats** at bottom center — glass pill: `rgba(10,10,15,0.7)` + `backdrop-filter: blur(20px)` + subtle border + 18px radius.
 - **"Esc zum Verlassen" hint** fades in top-center on entry and auto-fades out over 3.5s. Pressing Esc or clicking Grid/Focus buttons exits.
 - **No visible X button** (intentional — keyboard-only exit, confirmed design decision).
 ### 5. Participant Tile — Shared Component
 A participant is either in **audio-only**, **video**, or **sharing screen** mode.
 - Tile border: 1px `var(--line)`, radius 14 (10 in dock). Hover → border becomes accent. `.speaking` → 2px green border + green glow shadow. `.focused` → accent border.
 - **Audio-only**: centered avatar (72px large, 44px small). When `speaking`, a green ring pulses around the avatar (`::before` pseudo).
 - **Video**: placeholder stub (gradient background + centered avatar, since real video not in scope here).
 - **Screenshare**: renders a "fake window" — chrome row with 3 dots, content row with grey skeleton lines + one accent-tinted block. A glass badge top-left: monitor icon + "Max teilt Bildschirm" (badge hidden on small tiles).
 - **Meta row** (absolute, bottom 8px, glass): left shows crown (if me) + name + lock (if E2EE), right shows muted mic icon (red chip) and/or sharing icon (green chip).
 ### 6. Picture-in-Picture (PiP)
 A compact 260px pill docked bottom-right of the chat area:
 - 44px preview square (avatar of speaker, or mini shared-window placeholder if someone's sharing)
 - Title "Die Squad · {participantCount}"
 - Subtitle row: red pulsing dot + "Live · tippe zum Öffnen"
 - Circular red hangup button on the right
 - Whole thing is clickable → expands back to active call
 - Entrance animation: slide from bottom + fade in (`slideInCall`)
 - Shadow: standard + 3px accent glow ring
 ---
 ## Interactions & Behavior
 ### Call State Machine (lives in `ChatApp`)
 ```js
 // Primary state
 const [callScreen, setCallScreen] = useState('none'); // 'none' | 'incoming' | 'active' | 'pip'
 const [callMode, setCallMode]     = useState('grid'); // 'grid' | 'focus' | 'fullscreen'
 const [focusedId, setFocusedId]   = useState(firstSharingOrSpeakerId);
 const [callState, setCallState]   = useState({ muted: false, sharing: false, video: false, duration });
 ```
 ### Triggers & Transitions
 - Chat-header **phone icon** click → `setCallScreen('active')`, `callState.video = false`
 - Chat-header **video icon** click → `setCallScreen('active')`, `callState.video = true`
 - Grid tile click → `setFocusedId(id); setCallMode('focus')`
 - Focus/Grid/Fullscreen buttons in call topbar → set mode directly
 - Incoming "Annehmen" → `setCallScreen('active')`
 - Incoming "Ablehnen" → `setCallScreen('none')`
 - Hangup → `setCallScreen('none')`
 - PiP clicked → `setCallScreen('active')`
 - PiP hangup (circle red btn) → `stopPropagation()` + `setCallScreen('none')`
 - **Esc key** (global listener while `callScreen === 'active' && callMode === 'fullscreen'`) → `setCallMode('grid')`
 ### Chat Header Visibility Rule
 ```
 if (callScreen === 'active' && callMode !== 'fullscreen') → hide chat header
 else → show chat header
 ```
 ### Keyboard
 - `Esc` exits fullscreen (only). No other global keybindings.
 ---
 ## State Management
 Data shapes to wire up (see `components/call.jsx`):
 ```ts
 type Participant = {
  id: string;
  name: string;
  initial: string;
  color: 'violet' | 'amber' | 'rose' | 'teal';
  speaking: boolean;
  muted: boolean;
  video: boolean;
  sharing?: boolean;
  me?: boolean;
  e2ee: boolean;
 };
 type CallState = {
  muted: boolean;
  sharing: boolean;
  video: boolean;
  duration: string; // "HH:MM:SS"
 };
 ```
 In production these all come from your real-time signaling layer (WebRTC, LiveKit, etc.). The prototype uses static data for layout purposes only — wire them to your call store.

 No custom imagery. Everything is SVG icons (inlined in `components/icons.jsx`) and CSS. Fonts from Google Fonts: `Inter`, `Outfit`.
 Icons used in this scope: Chat, Friends, Shield, Settings, Logo, AddUser, Search, Phone, Video, Plus, Smile, Mic, MicOff, Send, Sun, Moon, Monitor, Lock, Crown, Grid, Focus, Maximize, PhoneOff.
 Replace with your codebase's icon library if one exists (e.g. lucide-react, heroicons) — names match lucide conventions.
 ---
 ## Implementation Checklist
 1. **Tokens**: add the Clean-variant light + dark CSS variables to your theme layer. If you already have a token system, map them to your existing names; otherwise create `--bg`, `--bg-2`, `--bg-3`, `--fg`, `--fg-muted`, `--line`, `--accent`, `--accent-fg`.
 2. **Icon rail + chat list + chat area**: refactor the current top-nav layout into the 3-column rail layout. Use your existing `Avatar`, `ChatItem`, `Message` components — only restyle.
 3. **Message bubbles**: outlined `them` / filled `me`, asymmetric radius, avatars only on last-of-run.
 4. **Call state machine**: add the four `useState` hooks to whatever component owns the chat screen. Hook the Esc key effect.
 5. **IncomingCallScreen**: new component, full-bleed overlay of `.chat-area`.
 6. **Call dock**: new component, renders above `.messages`. Hide chat-header while docked.
 7. **ParticipantTile**: audio / video / sharing modes, speaking ring, meta overlay.
 8. **Fullscreen mode**: switch call container to position absolute, floating strip + floating controls + Esc hint.
 9. **PiP**: minimizable widget bottom-right of chat area.
 10. **Wire real data**: replace `CALL_PARTICIPANTS` dummy with your live call-session participants.

 ## Notes for Claude Code
 - The Clean Rail variant is **Variante 2** in the prototype's variant switcher — ignore the other 5 aesthetic variants (Playful, Y2K, Cyberpunk, Warm, Brutal), they were design exploration and not the chosen direction.
 - Prefer composition over copying raw CSS. If the codebase has a `Card`, `Button`, `Tooltip`, use them.
 - Duration ("00:12:47") should tick live from the call start timestamp, not be static.
 - For WebRTC/media handling: this package specifies **UI only**. The media/signaling layer is out of scope and already exists in the codebase (see `CallUI.tsx`, `InCallPanel.tsx`).

Same pattern as handleInsert — base64 vs `\x…` hex serialisation varies across supabase/postgrest versions and was silently producing undecryptable ciphertext for edited messages on the receiver side Windows WebView2 background throttling: - ConversationsContext, useFriendships and useConversationMessages now listen for visibilitychange / focus / online events and trigger both a fresh REST refresh and a best-effort channel.subscribe() on wake. WebView2 aggressively throttles background WebSockets and was dropping realtime events entirely while the window was minimised, so new messages and friend acceptances only surfaced after a manual reload Bump tauri version 0.7.0 -> 0.7.1	2026-04-20 22:15:49 +02:00
byGalax	37becba7e2	feat: audio devices + fullscreen + banner cleanup (v0.7.0) Release desktop app / build (, windows-latest) (push) Has been cancelled Details Release desktop app / build (--target universal-apple-darwin --bundles app,updater, macos-14) (push) Has been cancelled Details Audio device selection: - audioSettings: persisted inputDeviceId + outputDeviceId - CallContext: uses stored input deviceId on mic enable, new setAudioInputDevice / setAudioOutputDevice actions that hot-swap without reconnect. Output swap applies HTMLMediaElement.setSinkId to every attached remote-audio element (LiveKit's switchActiveDevice only tracks elements it attached itself) - SettingsPage: new "Mikrofon" + "Ausgabegerät" selects with enumerateDevices, devicechange listener, permission-probe button. setSinkId-unsupported fallback is messaged but non-blocking Fullscreen: - FullscreenCall was absolute inset-0 z-40 which trapped it inside the <main> pane — sidebar + chat-list stayed visible. Switched to fixed inset-0 z-[60] so the call overlays the whole window Discord-style - ScreenShareViewer fullscreen: CSS-only toggle (native Fullscreen API unreliable under Tauri WKWebView), portalled to document.body when active so no ancestor stacking context can clip it.

byGalax	eb8f9857ff	feat: device backup/restore + quick wins + username casing Backup / restore flow: - deviceBackup.ts: v2 format wrapping userId + deviceId + privateKey in an encrypted JSON payload so restore can re-seed localStorage, vault, and reattach to the existing server-side device row without provisioning a new one (conv-key bundles stay valid, no "awaiting key" state) - shared/auth: restoreDeviceFromServerRecord — verifies session.user.id matches the backup's userId, confirms the server device row still exists, then writes the private key into the local secret store - BackupExportDialog — passphrase + confirm, generates portable string, copy + download .txt - DeviceRestore — textarea + passphrase → seeds vault + writes deviceId cache, treats this install as the original device - DevicePage now has tabs "Neu einrichten" / "Backup wiederherstellen" - BackupPromptBanner — post-registration nudge, reads sessionStorage signal from fresh provisions and persists "never-ask-again" in localStorage so it stops nagging - SettingsPage backup section: uses the new dialog; removes the dangerous in-place key import (restore now lives in the device flow) Username casing: - Migration 20260420000002 drops lower() from the handle_new_user trigger and widens the regex to [A-Za-z0-9_]. profiles.username is citext so uniqueness + lookups stay case-insensitive regardless of stored casing - Shared auth: trim() only, no toLowerCase on signup/lookups/search. ilike handles CI anyway and citext makes client normalisation redundant - AuthPage regex + input preserve case, FriendsPage search preserves case - i18n (de+en): updated username_hint / username_invalid / ERR_USERNAME_INVALID to reflect the new rule Quick wins: - React Router v7 future flags (v7_startTransition + v7_relativeSplatPath) set on BrowserRouter — silences the upgrade warning - appUpdates.checkForUpdate: swallow benign network/fetch/"could not fetch valid release JSON" cases silently instead of console spam - osNotify: persist an "asked" marker in localStorage so the permission prompt only fires once per install (OS already persists the answer, but the plugin re-queries loudly otherwise)	2026-04-20 19:07:31 +02:00
byGalax	de431386ea	feat: reply + search + forward + archive/mute + error boundary Messages: - Reply-to: hover action, composer chip with cancel, quote bubble inside the replying message with tap-to-jump + amber highlight ring - Search: header search button toggles in-conversation search bar with prev/next + match counter, auto-jump to active match - Forward: multi-select conversation picker. Attachments are now carried over: download + decrypt source, re-encrypt under each target conv-key, re-upload with fresh per-attachment keys, insert new attachment rows Conversations: - Archive + mute per member. New migration 20260420000001 adds `archived` + `muted_until` on conversation_members. Shared helpers: setConversationArchived / setConversationMutedUntil / isConversationMuted - ChatsPage: archive toggle in header with unread badge for archived bucket, split active/archived lists, muted indicator (BellOff icon, dimmed unread badge) - ConversationRowMenu via createPortal (escapes sidebar overflow clip), forwardRef-based MenuItem so submenu positioning refs survive React 18 - ConversationsContext: suppresses notification sound + OS notif when target conversation is muted - Refresh on `profiles UPDATE` realtime so peer avatar / displayName changes flow to conversation.members without manual refresh Resilience: - ErrorBoundary (Discord-style): centred spinner + escalating copy, no manual reload button. Backoff retry schedule [2s, 4s, 8s, 15s, 30s]. Uses a keyed Fragment (not a div wrapper) so flex h-full chains survive - App wrapped root + per-route RouteBoundary, conversation-level boundary - AuthContext: flip `ready` immediately on cached session read; validate getUser in background so a stalled/offline Supabase doesn't freeze the app on the loading spinner Crypto: - Swap libsodium-wrappers -> libsodium-wrappers-sumo (compact build was missing crypto_pwhash so Argon2id vault KDF threw, falling back to plaintext localStorage on every launch) - Shim d.ts for sumo types (sumo is API superset, no official types ship) - vite optimizeDeps includes sumo with the "require" condition - secureFileStore: exists(dir) check before mkdir; surface genuine permission errors instead of silent catch Tauri: - fs scope adds `$APPLOCALDATA` direct entry (not just /**) so the app data directory itself can be mkdir'd on first launch Chat layout: - Skip call_event messages when computing avatar run boundaries so a regular bubble followed by a call event from the same sender still shows its avatar	2026-04-20 15:42:49 +02:00
byGalax	1fab2edc57	fix(messages): peer avatar visibility in chat bubbles - ConversationsContext: subscribe to profiles UPDATE realtime so conversation members[].profile picks up peer avatar / displayName changes without a manual refresh - ConversationPage: skip call_event messages when computing run boundaries. Previously a peer bubble followed by a call event from the same sender was treated as mid-run -> avatar slot collapsed to a placeholder - DM peer-profile fallback already added in previous commit covers transient member-lookup misses	2026-04-20 00:49:21 +02:00
