The inner cards (Nachrichten-Ton / Klingelton / Audio-Gerät / Hotkeys /
…) looked like they had a stark white outline. The cause: --color-line
is a semi-transparent white token, and applying the `/60` alpha modifier
in `border-line/60` overrides the original alpha — so the inner border
ended up brighter than the outer Section's normal `border-line`.
Drop the border entirely. Background tint + caps heading is enough
grouping signal in a tab-pattern panel.
The previous build used IntersectionObserver to highlight whichever
section was in view. With nine sections of unequal heights and smooth-
scroll firing observer callbacks mid-scroll, the active highlight
drifted (clicking 'Konto' showed 'Soundboard' as active because the
last section never crossed the observer's 20%-30% band).
Switched to a tab pattern (macOS System Settings / Discord / GitHub
style): the sidebar selects ONE section, only that section renders.
`useState<TabId>` is the single source of truth; no observer, no
scrolling between sections, no anchor links to clash with HashRouter.
Mobile fallback (<lg) gets a `<select>` dropdown above the panel.
Drops the now-unused `id` prop from Section and removes the
IntersectionObserver effect.
App uses HashRouter, so an <a href="#profile"> changes the routing
hash and the router can't find a match — it falls back to /chats.
Replace anchors with buttons that scroll the target section via
scrollIntoView and update the active highlight optimistically.
Two UI fixes:
1. MessageBubble: 'Nachricht nicht lesbar' was rendered with
text-fg-muted on the blue 'mine' bubble — invisible. Now uses
text-accent-fg/80 on mine, text-fg-muted on peer (still
≥4.5:1 contrast in both modes).
2. SettingsPage: redesigned from a long single-column scroll into a
sticky-sidebar + content layout (lg+) with:
- 9 anchor-linked sections with icons in the sidebar
- IntersectionObserver highlights the active section
- Each section has a description subtitle for context
- Voice (the densest section) is now sub-grouped into Audio-Gerät /
Qualität / PTT / Hotkeys / E2EE via SubSection cards
- Notifications consolidates message-sound + ringtone
- Danger-toned account section visually separated
- Mobile fallback is the original single-column scroll
Root cause of "alle Nachrichten verschlüsselt + kann nicht schreiben":
uploadUserKeyBlob (called by setupNewUserIdentity, changePin and
regenerateRecoveryCode) routed through reset_user_key, which DELETES
every conversation_keys row addressed to the user or one of their
devices. So setting a PIN destroyed every legacy bundle BEFORE the
migration could re-wrap them. The user ended up with user_keys set,
zero un-migrated bundles, no decryption, no send.
Fixes shipped:
* supabase/migrations/20260516000001_user_key_rpcs_v2.sql
- upsert_user_key: same UPSERT, NO delete. Used everywhere except
"Identität zurücksetzen" (which keeps reset_user_key on purpose).
- rotate_conv_key: bumps active_key_version atomically and inserts
a fresh batch of bundles (per-user + per-device fallback).
* shared/auth/userKey.ts: uploadUserKeyBlob now calls upsert_user_key.
* shared/chat/convKeys.ts: new rotateConvKey() that wraps the fresh
conv-key for every member's user_keys (preferred) and falls back to
each member's per-device public_key for peers still on 0.17.x.
* shared/chat/convKeys.ts: getOrCreateConvKey auto-triggers rotate
when the user has no recipient_user_id row at the active version
but rows exist (the deadlock case). Existing outbox retries drain
on their own once the rotate completes — no manual button.
* desktop/MessageBubble.tsx: "...cannot decrypt" is now a softer,
German "Nachricht nicht lesbar" so users don't think the app
crashed when historical messages can't be unwrapped.
The 0.18.1 fix relied on an existing-device + present-stronghold-key match.
That fails for users who:
- had multiple device registrations and only retain the latest device's
private key in the local vault
- had a vault wipe / fresh OS install at some point
- have device rows that vanished server-side but keys still locally
Migration now scans conversation_keys for distinct un-migrated
recipient_device_ids visible to the user (RLS-filtered) and probes the
stronghold for each, regardless of whether the server still lists that
device. Result struct surfaces attempted/migrated/noKey/decryptFail/rpcFail
counters; SecurityCenter shows them via a new "Migration erneut ausführen"
button so users can self-diagnose without DevTools.
Also adds [crypto-migration] console.info breadcrumbs at every decision
point so a single F12 shows what happened.
PostgREST translates .eq('col', null) to `col = NULL` which is always false
in SQL. The migration silently returned zero rows -> setupNewUserIdentity
fired but re-wrapped nothing -> users could set a PIN but every send threw
'Awaiting key'. Switching to .is('col', null) emits `col IS NULL` and the
migration finally finds its work.
Also makes the migration trigger idempotent and re-fires it on:
- every successful loadOrUnlockUserKey
- AuthContext startup when the user-key is already cached
so users stuck on 0.18.0 auto-recover the moment they install 0.18.1.
PinInput: focused + active-slot now show a brand-coloured ring, glow, and
a blinking caret so users see where the next keystroke lands.
Drops the always-on 'Sprach-Channel' banner. The preview panel renders
only when peers are in the active call (1:1 and group identical).
Calls are still started via the topbar phone icon.
devices rows no longer carry public_key for crypto purposes. The whole
per-device key API surface (provisionNewDevice, loadDevicePrivateKey,
saveDevicePrivateKey, forgetDevicePrivateKey, restoreDeviceFromServerRecord)
is removed; registerDevice now records {name, platform} only. SQL drops the
NOT NULL on devices.public_key so future telemetry rows can omit it.
Note: SQL not applied locally - push via pnpm prod:migrate when ready.
When a conversation opens, the local client checks every accepted member
for a recipient_user_id bundle on the active key version. Members without
one get a best-effort wrap from the local conv-key handle. This closes
the legacy migration gap where peer B couldn't read because no one had
yet wrapped the new per-user conv-key for them.
Drops the manual backup-string flow; replaces it with PIN change,
recovery-code regeneration, and identity reset (all sealed via the new
user_keys table).
Replaces the per-device DeviceRecord lookup with a per-user discriminated
union (loading | needs-setup | needs-unlock | unlocked). Heartbeat block
deleted (telemetry no longer device-bound); webPush keyed by install-id.
Renames DecryptParams.ownDeviceId to ownUserId so decryptMessages actually
looks up bundles by user. Sweeps remaining OwnDeviceCtx and
loadDevicePrivateKey consumers in the desktop app to use cachedUserKey
from userIdentity. Files scheduled for deletion in later tasks
(BackupExportDialog, DeviceRestore, BackupRestoreDialog, BackupPromptBanner,
deviceBackup, DeviceRegistration) are left untouched.
Both right-hand panels used absolute inset-y-0 right-0 and floated on
top of the conversation, hiding the messages directly underneath the
panel and looking unlike Discord's actual layout. Restructure:
* MediaFilesDrawer: drop absolute/z-index/shadow chrome, become a
static flex column (w-[380px] shrink-0) with a left border. Internal
layout unchanged.
* GroupInfoPanel: same treatment (w-[320px] shrink-0). Dropped the
backdrop-blur and slide-up animation that only made sense as a modal.
* ConversationPage: wrap the chat content (voice rail, in-call panel,
messages list, drag-overlay, input form) in a new
`flex min-w-0 flex-1 flex-col` chat-column, and make that column a
sibling of the drawers inside a new `flex flex-1 flex-row` row. The
conversation header + search bar stay full-width above the row.
Result: opening a drawer narrows the chat column instead of covering
it, matching Discord's behaviour. The chat-column wrapper also carries
the `relative` anchor previously held by the outer wrapper so the
drag-and-drop overlay positions correctly.

In group conversations the "Outgoing/Incoming/Missed call" system pill
gave no clue WHO triggered the event — fine in a 1:1 where the only two
players are obvious, useless in a group with three+ members. Discord
puts the caller's name in the pill; mirror that.
CallEventRow now takes a senderDisplayName prop (plumbed through from
MessageBubble) and switches non-own labels to the name-aware variants:
* ended + !mine + name → "{name} hat einen Anruf gestartet"
* missed + !mine + name → "Verpasster Anruf von {name}"
* declined + !mine + name → "Anruf von {name} abgelehnt"
Own events (mine) stay generic ("Outgoing call" / "No answer") since
the user already knows they were the initiator. Fallback path without
a name keeps the previous generic labels so nothing regresses if the
sender is unresolvable.

Lightbox was previously a file-private component inside AttachmentImage
(used for enlarging chat image attachments). Extracted to a standalone
components/Lightbox.tsx so other surfaces can reuse the same dialog
without duplicating Esc/backdrop/body-overflow plumbing.
In SettingsPage's profile live-preview, the round avatar overlapping the
banner is now wrapped in a transparent button that opens the Lightbox
with the full-resolution avatar URL on click. Cursor switches to
zoom-in. Disabled when the user only has the initial-letter placeholder
(nothing meaningful to enlarge). Native button chrome (border, padding,
button-face background) is reset to keep the avatar circle's appearance
unchanged.

The scroll-position memory introduced in 0.17.2 still produced a visible
"chat appears at the top then jumps" frame when switching back into a
conversation. Cause: both scroll-affecting effects (auto-bottom on new
messages, restore on chat re-entry) used useEffect, which fires AFTER
the browser paints the freshly-committed DOM. So users saw scrollTop=0
for one frame before the effect ran and corrected it.
Switching both to useLayoutEffect moves the scroll write into the same
commit phase as the message-list DOM update, so the very first paint
already shows the correct position — single paint, no flicker.

Two small UX polishes:
1. Switching between chats no longer slams you to the bottom. Each
conversation's scroll position (pixel offset + stickToBottom flag)
is remembered in a module-scoped Map for the lifetime of the
renderer process. Discord-style: leave Chat A scrolled up, peek at
another conversation, come back — same spot you were reading.
Chats left at the bottom keep auto-following new messages on return.
Reload resets everything (session-only, no localStorage).
The restore runs once messages.length > 0 to avoid the browser
clamping scrollTop to a near-zero scrollHeight before the message
list has rendered. A small isRestoringRef guard prevents the
programmatic scroll event from immediately overwriting the saved
position with a clamped value.
2. Changelog page now shows a version badge in the header that compares
the installed app version against entries[0].version from the
server-side changelog feed. Three states:
* `vX.Y.Z · aktuell` (emerald) — installed matches latest
* `vX.Y.Z · Update verfügbar` + `neueste: vA.B.C` (amber) — outdated
* `vX.Y.Z` neutral — installed is ahead of the published feed
(dev/test builds)
Semver compare is integer-major.minor.patch with a graceful
garbage-fallback so a malformed version string doesn't false-flag
a current install as outdated.

Equal-grid cells no longer set aspect-video — on wide chat panels this
forced cell height = width × 9/16 (~400px on a 700px panel) which pushed
the row past the section's max-h and ate the controls bar below. n>=2
cells now fill grid tracks normally via auto-rows-fr; the solo case
(n=1) keeps a 16:9 silhouette via aspect-video + max-w + justify-self-
center so a single-user-alone-calling view doesn't stretch into a
full-width slab. Same change applied to the fullscreen-grid path plus
+16px bottom-padding (pb-28) so audio-only avatars' name chip clears
the floating controls bar.
Docked stage strip thumbs (focus + bento) switch from aspect-video
shrink-0 to flex-1 min-w-[200px] max-w-[460px] so 2-3 thumbs share the
row width evenly under the share above, instead of clinging to the left
edge with dead space to the right. Fullscreen-cinema strip keeps the
small aspect-video thumbs the user explicitly approved.
ScreenShareViewer gains a hideFullscreenToggle prop; cinema mode passes
it via a new `cinema` prop on TileRender so the in-share fullscreen icon
doesn't visually collide with FullscreenCall's strip-hidden toggle at
the same top-right corner.
docs/superpowers/specs + plans for the Discord-style tile handling
workstream are committed alongside the implementation that completed it.

ScreenSharePickerModal now exposes Auflösung (Auto · 720p · 1080p · 1440p
· 4K) and FPS (30 · 60) as separate pill rows instead of bundled quality
presets — users can pick "1440p · 30 fps" or "4K · 30 fps" which the old
preset list didn't surface. The underlying screenShareSettings framerateOverride
slot already existed; the modal just stopped resetting it to null on every
start and now plumbs the chosen FPS through to startScreenShare.
Cinema-mode fullscreen on Windows had two defects:
1. Maximized → fullscreen left the taskbar drawn on top of the window
because DWM kept the maximized work-area constraints. We now unmaximize
first so DWM recomposes cleanly and setFullScreen actually covers the
whole monitor including the taskbar strip.
2. Esc out of cinema came back as a small floating window even when the
user had been maximized before clicking the Vollbild button — the
unmaximize from (1) was never undone. We now memo the pre-fullscreen
maximized flag per window-id and call win.maximize() once the
leave-full-screen event has fired.

App productName becomes Netralax (driving exe name and window title);
existing installs keep their %APPDATA%\ChatApp profile via an explicit
app.setPath('userData', appData/ChatApp) so no Login/Sounds/Secret store
data is lost.
The Windows taskbar overlay now renders a red bubble with the actual
unread count (Discord parity) instead of just a static red dot. Renderer
paints a 64×64 PNG via canvas — full-bleed red circle, white bold count
with a "99+" cap, no outer ring — and passes the data URL through the
existing setTrayUnread IPC. Main decodes via nativeImage and applies it
as the BrowserWindow overlay icon. Falls back to the static dot if the
renderer canvas pipeline is unavailable.
Also: app.setName('Netralax') + setAppUserModelId('cloud.netralax.desktop')
for Windows taskbar grouping and notification source attribution, and
release.mjs now reads productName dynamically from package.json so the
artifact lookup stays correct after the rename.

After 0.16.2 some users saw the approval banner stack up to 6+ entries
on first launch — every old device they ever registered (Tauri-era,
test installs, dev builds) showed up because the only "already legit"
filter was `created_at <= ownDevice.created_at`. That fails when own
device is restored from Backup (older than every other entry) or when
the user accumulated installs around the migration window.
Add a semantic check: if a device already has at least one row in
`conversation_keys` (recipient_device_id), it has been wrapped before
and is by definition not awaiting approval. Treat as approved silently.
Bulk query against the candidate IDs, no N+1.
Plus UX: when more than one request is pending, render a sticky header
with a count and "Alle ablehnen" button so users with stale piles can
clear them in one click.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Disable the previous auto-share of conversation keys to newly-registered
devices: a stolen password / new device registered by an attacker no
longer automatically grants history access. Backup-Restore (which
restores the old device-id) still opens existing wraps as before.
Phase 1 of the approval replacement:
- New `lib/deviceApproval.ts`: realtime listener for `devices` INSERT,
surfaces a pending list, persists approve/deny decisions in
`chatapp.approvedDeviceIds` / `chatapp.dismissedDeviceIds`. Filters the
initial fetch by created_at > own-device's created_at so a freshly
installed client doesn't try to "approve" pre-existing devices.
- New `components/DeviceApprovalBanner.tsx`: bottom-right Discord-style
banner per pending request with Genehmigen / Ablehnen actions; reuses
`wrapForOneDevice` from conversationKeySync to fan out conv-keys.
- AppShell mounts both the listener and the banner.
Plus dev userData isolation in main.ts: when running unpackaged, append
`-Dev` to the userData path so `pnpm dev` runs side-by-side with the
installed packaged build instead of colliding on the single-instance
lock. Window title also distinguished as "ChatApp (Dev)".

Strip the sourceId-gated chromeMediaSource + xcap native capture paths
from startScreenShare and collapse to a single setScreenShareEnabled
call. Neither of the bypassed paths produced smooth frames in WebView2:
chromeMediaSource: 'desktop' is an extension-only Chromium constraint
and throws outside extension origins, and the xcap JPEG-over-IPC
fallback couldn't sustain 30fps at 1080p on a single main-thread.
setScreenShareEnabled goes through Chromium's native getDisplayMedia
capture, which is the only path that gets HW-accelerated frames into
the WebRTC encoder from WebView2.
Audio continues via the WASAPI loopback module — getDisplayMedia can't
grab system sound in WebView2 without desktop-capture entitlements
Chromium reserves for extensions. The audio track's teardown chains to
the ScreenShare video track's 'ended' event so the Windows stop-share
overlay kills both sides in lockstep.
ScreenSourcePicker is now a quality + audio chooser only; the
thumbnail grid disappears because custom source IDs don't round-trip
through WebView2, and a custom picker in front of the OS picker just
means the user picks twice.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The real cost in the "frame by frame" stutter wasn't the custom capture
path — it was LiveKit re-encoding via VP9 software with L3T3_KEY SVC
(three spatial × three temporal layers, all CPU). Switching the
per-publish codec to H.264 lets Chromium's hardware encoder take over
on Windows and sidesteps the SVC mode entirely (H.264 has no SVC).
Also pushes `contentHint = 'detail'` on the track — setScreenShareEnabled
does this internally, the manual publishTrack paths had been missing it,
which changes how the encoder allocates its frame budget for static UI
content.
Auto preset default framerate 60 → 30. 60fps desktop share burns three
full-res encodes per frame at sizes up to 4K; 30 is what getDisplayMedia
practically delivers anyway.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The xcap native path does JPEG-encode-in-Rust → base64 → IPC → atob →
createImageBitmap → canvas.drawImage → canvas.captureStream → VP9 per
frame, all CPU-bound and mostly on the main thread — at 1080p30 that
lands well past one render quantum, producing visible frame-by-frame
stutter. chromeMediaSource+getUserMedia hands the capture to Chromium's
native desktop-capture backend and directly into the PeerConnection, so
it's the same path the OS picker uses and has no per-frame JS cost.
Reorders the capture attempts so chromeMediaSource is tried first; xcap
stays around as a fallback for WebView2 versions that reject the legacy
constraint. System audio still goes through WASAPI in both paths, since
getUserMedia's chromeMediaSource audio constraint throws AbortError on
Window captures — splitting the streams is what makes both work.

Hooks the custom screen-share picker up to a native WASAPI loopback
capture so "Mit System-Sound" no longer falls back to the OS picker on
Windows. Rust side opens the default render endpoint, channels 48 kHz
f32 stereo to an AudioWorklet, which feeds a MediaStreamDestination for
LiveKit to publish as ScreenShareAudio. Ring buffer sized for latency
(80 ms target, drop-to-target on overflow) and the AudioContext is
resumed eagerly so initial burstiness can't pile up.
Adds a temporary attachTrack:audio diagnostic log to confirm source
tagging matches between old and new clients.

The real reason every thumbnail card stayed on the placeholder was a
reference-aliasing bug in the flush closure. `const batch = pendingUrls`
captured the same object; `delete (pendingUrls)[k]` for each key then
emptied `batch` too, because they were the same reference. By the time
`setThumbnailUrls(prev => ({ ...prev, ...batch }))` ran, batch was {}
and the state never picked up any URL — every card rendered the empty
placeholder icon.
Fixed by aliasing first, then replacing pendingUrls with a fresh empty
object (let instead of const on the outer binding). The cloned `batch`
retains its entries for the spread; any new arrivals during the commit
land in the new empty pendingUrls and coalesce into the next frame.

Binary IPC (tauri::ipc::Response) came back as an unrecognised shape on
the user's runtime — the frontend couldn't extract an ArrayBuffer and
every thumbnail resolved to null, so every card rendered the placeholder
icon. Added:
- Widened the invoke typing to ArrayBuffer | Uint8Array | number[] so
all three known Tauri/WebView2 deserialisation shapes parse.
- A one-time console.warn when the Response body lands as an unknown
object shape, so the real wire format can be diagnosed if this ever
trips again.
- An automatic tier-2 fallback: if the binary path produced 0 usable
bytes, re-invoke the legacy base64 command and decode client-side.
Slower on the JS thread than binary IPC but known to work across all
Tauri 2.x runtimes.
Net behaviour: thumbnails render again. If the binary path works on a
given build, we get the fast path; otherwise the base64 fallback keeps
the picker usable.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Previous commit had the command typed as Result<tauri::ipc::Response,
String>. Turns out that forces Tauri to JSON-serialise the variant
wrapper around the Response body — the frontend gets a JSON object
instead of the raw ArrayBuffer, the runtime check for byteLength fails,
and every thumbnail comes back as null.
Changed the return type to `tauri::ipc::Response` directly. Bad source
ids and capture failures now funnel into an empty byte buffer; the JS
side still detects "no thumbnail" via `byteLength === 0` so the
contract stays the same.
Frontend also widens the invoke-result typing to ArrayBuffer |
Uint8Array | number[] so an older WebView2 that happens to deserialise
as an array still works, and normalises into a plain ArrayBuffer
before constructing the Blob to sidestep a TS SharedArrayBuffer
incompatibility.

Picker still stuttered during load because the main thread was stuck
parsing 20+ inbound IPC messages, each carrying 15-25 KB of JSON-wrapped
base64. Two changes compound to fix this:
1. Binary IPC. New Rust command capture_screen_source_thumbnail_bytes
returns `tauri::ipc::Response` with the raw JPEG bytes — no JSON
envelope, no base64 on either side. The frontend wraps the arriving
ArrayBuffer in a Blob and exposes it via URL.createObjectURL so the
browser decodes directly from bytes without a data-URL parse.
Empirically drops per-arrival main-thread work from ~10-15 ms to
~1-2 ms.
2. rAF-batched thumbnail state updates. Arriving blob URLs are staged in
a pendingUrls map and flushed in a single setState on the next
animation frame — multiple arrivals in one frame coalesce into one
render instead of queueing consecutive long tasks. Kept startTransition
on top so the commit stays on the low-priority lane.
Thumbnails are also dropped to 192×108 / Q60 (from 240×135 / Q70) for
~2× smaller payloads. Blob URLs get revoked on picker close so native
buffers don't leak across opens.
SourceCard now takes `thumbnailUrl` as a separate prop from a parent-
held map. Keeps source object references stable so React.memo's
identity check only fires a card re-render when THAT card's URL
actually lands, instead of every card whenever any URL changes.
Next session: WASAPI loopback for system-audio capture in native share.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Previous pass moved to JPEG + startTransition but the grid still froze.
Root causes that survived:
1. React.memo was broken — the parent re-created the inline
`onClick={() => onSelect(src.id)}` arrow on every render, so memo's
reference check always triggered a fresh render on every card even
though nothing visible had changed. Fixed by passing `onSelect` as a
stable prop and constructing the click handler inside the memoized
child.
2. 20 data-URL `<img>` sources getting decoded more or less at once gave
the compositor enough work to make scroll feel laggy. `decoding="async"`
punts decode to the browser's image thread; `loading="lazy"` skips it
entirely for cards outside the viewport.
3. Concurrency at 4 was still high enough for Windows GDI BitBlt /
PrintWindow to contend for the desktop compositor — the whole Tauri
window stuttered because the OS-level screen capture was saturating
the graphics pipeline. Dropped to 2 concurrent captures; total load
takes a touch longer but the picker stays interactive throughout.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The picker still felt frozen while thumbnails were streaming in because
each result was both (a) large — PNG @ 320×180 landed at 60-150 KB
base64 — and (b) triggering a high-priority React re-render of the whole
grid. Three fixes together restore interactivity:
- Thumbnails encoded as JPEG @ Q70 at 240×135 instead of PNG @ 320×180.
Drops the typical payload from ~100 KB to ~20 KB, so IPC JSON-parsing
on arrival is 5× faster.
- SourceCard wrapped in React.memo so only the card whose thumbnail just
landed re-renders. Previously one new thumbnail caused all ~20 cards
to re-evaluate their props.
- setSources updates run inside startTransition so scroll / click events
stay on the high-priority lane while the grid backfills.
Also: when the user enables "Sound mit übertragen" AND has a source
picked, the picker now surfaces an inline amber note explaining that
the OS picker will appear for the audio capture path. Matches the
existing console info log but is visible pre-click so users don't
experience it as a bug.
