The old 2x2 grid for 3+ members produced a cramped, misaligned look
(circles cut off inside their own border, no overlap, just four small
disks in a grid). The 2-member overlap aesthetic — equal-size tiles
that overlap diagonally — was the visual gold standard but only
existed for that one count.
Extend the same "huddle of overlapping faces" aesthetic to all
member counts:
• 3 members → equilateral triangle of 62%-size tiles (top, bl, br)
• 4 members → diamond of 58%-size tiles (top, right, bottom, left)
• 5-10 members → diamond with `+N` overflow occupying the bottom
slot (z-index boosted above neighbors so the digit is never clipped)
Tiles are positioned radially around the box center on a circle of
radius (S − T) / 2 so the farthest edges of each tile graze the
bounding rect — no clipping, no wasted whitespace. Z-index descends
clockwise from the top slot so each tile tucks slightly under its
clockwise neighbor, mirroring the 2-member z-stack.
The 0/1/2-member cases and the icon-override branch are unchanged.
Props interface unchanged — no call-site updates needed.
Tests updated to assert the new layout markers (`triangle`, `diamond`)
and to verify the geometry (top tile in triangle has smallest `top`;
overflow tile in diamond has largest `top`). 11/11 AvatarStack tests
pass; 360/360 web tests pass; typecheck clean.
design-system.md spec updated with the new layout table + geometry
section.
Snapshot of in-progress work parked here so group-DM-polish can land
cleanly on main. Touches MainContent + mobile-ui.md which overlap with
group-DM-polish; rebase onto post-merge main and resolve conflicts on
those two files manually.
Files: MainContent, MessageInput, MobileVoiceFullScreen (+test), StreamTile,
VoiceUser, useLiveKit, useVisualViewportInset, AudioManager, voiceStore,
voice utils, mobile-ui.md, voice.md, mobile-parity handoff doc.
getProfileReferencedFilenames() didn't include dm_channels.icon, so the
storage janitor deleted group DM icons within ~1 hour:
- Owner instance: PATCH /api/dm/:id leaves an attachments row with
messageId=null and dmMessageId=null. After 1h, getUnlinkedAttachments
flags it and cleanupStorage phase 2 deletes the file because the
filename isn't in profileReferenced.
- Receiver instance: downloadProfileAsset writes the icon directly to
uploadDir with no attachments row. cleanupStorage phase 1 treats it
as orphaned and deletes it.
Fix: include dm_channels.icon (non-null, not soft-deleted, not http://)
in the profile-referenced set. Soft-deleted DMs are excluded so their
files still get reaped by cleanupSoftDeletedDmChannels. Absolute URLs
are skipped because they live on a remote instance.
Also mirror the avatar precedent at the PATCH endpoint by deleting the
new icon's standalone attachment row — the file is now protected via
dm_channels.icon, matching users.ts:473.
Refactors the leave-DM destructive core into a shared `removeDmMember`
helper and adds a kick endpoint that reuses it. Both endpoints write the
`member_removed` system message, delete the dm_members + read_states
rows, broadcast `dm_member_removed`, and queue a federation
`member_remove` event with the appropriate `reason` ('leave' | 'kick').
Branching invariants preserved by the helper:
- Ownership transfer fires only on self-leave when the leaver was the
owner. Kicks cannot orphan a group (the owner is still present), so
the transfer block is skipped.
- Soft-delete on last-member-empty fires only on self-leave. Kicks are
guaranteed to leave the owner behind, so the channel can never be
empty after a kick.
Endpoint validation:
- 1-on-1 DM → 400 'Cannot kick from a 1-on-1 DM'
- Caller not the owner → 403 'Only the group owner can remove members'
- Self-target → 400 'Owners cannot kick themselves; use leave instead'
- Target not a member → 404
- Channel missing or soft-deleted → 404
The kicked user is also evicted from the DM voice room (mirroring the
self-leave path) and receives `dm_channel_closed` so the client closes
the channel locally.
config.ts requires JWT_SECRET at module-load time. Since `.env` is gitignored
it doesn't propagate to git worktrees, fresh clones, or CI without secrets —
producing 200+ confusing cascade failures (vitest module-mock errors that
look unrelated to the real cause).
Add a vitest setupFile that sets JWT_SECRET to a fixed test-only value via
`??=`, so a real .env still wins where one exists. Tests are now hermetic:
clone the repo, `pnpm install`, `pnpm --filter server test` → 477/477 pass.
Multi-pass mobile chat polish landed across this session.
- MessageInput is now a floating glass-bubble (`position: absolute`) on both desktop and mobile — last messages scroll *behind* the translucent bubble. MobileChatScreen wraps MessageList + MessageInput in a `relative` parent so absolute positioning resolves. Removed the prior in-flow mobile branch that clipped message-list bottom against an invisible barrier.
- iOS PWA keyboard handling: new `useVisualViewportInset` hook subscribes to `visualViewport.resize/scroll` AND polls `vv.height` for ~600ms after focusin (iOS PWA standalone often fails to dispatch resize for keyboard transitions). MobileShell sizes its container to `vv.height` when keyboard is open — `bottom: 0` on the composer naturally lands flush with the keyboard top, regardless of how reliably resize events fire. Composer uses 6px gap above home indicator (keyboard closed) and 0px gap above keyboard (keyboard open). Added `interactive-widget=resizes-content` viewport meta as the cleaner native equivalent for Chrome/Android.
- MessageList bottom padding is dynamic via `--composer-clearance` CSS variable. MessageInput writes `composerHeight + bottomOffset + 12px` to its parent via ResizeObserver — re-fires on textarea autosize, reply banner, attachment tile growth, parent resize. Last message always has 12px breathing room above the bubble regardless of composer state.
- AttachmentRenderer generic file chip: `max-w-full sm:max-w-[400px]` on outer + `min-w-0` + `flex-shrink-0` on icon + `flex-1` on text + `flex-wrap` on badge row. Long filenames now ellipsize cleanly on narrow viewports instead of pushing the chip off-screen.
- New `useDragToClose` hook: shared bottom-sheet drag-down-to-dismiss gesture. Spread on handle/header only (body scrolling unaffected). 6px deadzone, 100px or 0.5px/ms velocity threshold, 200ms `cubic-bezier(0.22, 1, 0.36, 1)` close-out animation, rAF-staged transform for a stable from-value. `hasInteracted` latch prevents the open keyframe from re-firing mid-close (the bounce-up-then-vanish bug). Wired into InputPopover (emoji/GIF), MobileVoiceJoinSheet, MobileFolderSheet.
Specs: docs/systems/mobile-ui.md (Floating Composer + Drag-to-Close sections), docs/systems/message-list.md (--composer-clearance), docs/systems/design-system.md (glass-bubble row references).
Brings mobile to skeleton parity with desktop. Two mobile-specific renders, plus a fix for the empty-state mascot flashing on every space switch.
- MobileSpacesScreen: shimmer skeleton for the channel list while `useSpaceStore.loadingSpaceId === selectedSpaceId` (uncategorized rows + category header + categorized rows). Mirrors desktop ChannelSidebar's `showChannelSkeleton`. Gated through `useDelayedLoading` so cached/fast loads don't flash the placeholder.
- MobileMembersScreen: shimmer skeleton for the member list (two role-section headers + circular avatars + name bars). Mirrors desktop MemberSidebar's `showMemberSkeleton`.
- Empty-state "No channels yet." mascot was firing on EVERY space switch for ~50–200 ms — `state.channels` only ever holds the most-recently loaded space's channels, so `spaceChannels` filters to `[]` immediately on selection change while `loadSpaceDetail` is still in flight. New `loadedSpaceIds: Set<string>` on useSpaceStore, populated only on `loadSpaceDetail` success and pruned on space removal events. The mascot is now gated on `loadedSpaceIds.has(selectedSpaceId)` so it only fires when the space is *settled* with zero channels.
Reuses the existing `.skeleton` / `.skeleton-bar` / `.skeleton-circle` CSS primitives + `useDelayedLoading` hook (no new shared `<Skeleton />` primitive — sites need row-specific geometry, parameterizing would either over-abstract or duplicate the inline approach).
Specs: docs/systems/mobile-ui.md (Loading Skeletons inventory + per-screen skeleton bullets + settle-gate rationale); docs/systems/spaces.md (Client Load State subsection covering loadingSpaceId vs loadedSpaceIds).
Two compounding root causes produced a "PiP-style grey view" briefly visible after Join Voice on mobile:
1. MobileSpacesScreen.handleVoiceJoin pushed 'voice' onto the mobile stack. MobileShell.screenMap only has 'voice-full' — the renderer returned null for 'voice' while the root screen sat under `visibility: hidden` (stack length > 0). Corrected to 'voice-full' with an explanatory comment.
2. AppLayout mounted the desktop <PictureInPicture /> in the mobile branch too. Its visibility check `(isInServerVoice || isInDmCall) && !voiceFullscreen` is true the moment currentVoiceChannelId is set, so the desktop PiP rendered as the only visible UI on top of the hidden mobile shell. Removed from the mobile branch; kept on desktop. Added a comment to prevent regression.
Mobile owns its voice overlay chrome exclusively via MobileVoiceMiniBar + MobileVoiceFullScreen.
Spec: docs/systems/mobile-ui.md gains a "Voice Join Flow (Mobile)" subsection and a leading paragraph in "Voice Overlay" stating that PiP is desktop-only.
Closes the mobile parity push.
- MobileVoiceJoinSheet: full pre-join camera preview. Dormant-by-default (never auto-fires getUserMedia), explicit user gesture to arm, hard-bound disarm on sheet close (any path). Camera picker popup portaled to document.body so a long device list stays scrollable above the aspect-video preview tile (max-height min(50vh,320px), iOS scroll momentum). iOS Safari-safe: autoPlay playsInline muted + post-await play().
- MobileSettingsScreen: Keybinds + Desktop sections gated on isElectron(); they reuse the existing KeybindsPanel/DesktopPanel which are already mobile-fit. screenMap entries added in MobileShell. (Verify on Electron desktop build at narrow viewport.)
- ToastContainer: real overlap was hiding the voice-fullscreen control bar. Mobile branch now reads isMobile/mobileStack/currentVoiceChannelId and computes the bottom offset across five mobile states (voice-full / pushed+voice / pushed / root+voice / root), all with safe-area-inset-bottom; left-3 right-3 + items-center keeps toasts in the safe-tap zone. Desktop bottom-6 right-6 unchanged.
Specs: docs/systems/mobile-ui.md (Toast Positioning section, screenMap rows, Electron-entry rationale, z-index row); docs/systems/voice.md (Mobile pre-join preview subsection covering lifecycle + camera picker portal).
Adds sticky `lastSelectedSpaceId` to useSpaceStore. Updated on every
setCurrentSpace(non-null) and on loadSpaceDetail success; NOT cleared by
setCurrentSpace(null), so the @me URL effect in AppLayout no longer wipes
the memory. Cleared only when the remembered space is actually removed
(deleteSpace / leaveSpace / removeSpace / removeInstanceSpaces / reset).
Ephemeral — URL drives initial state on reload.
MobileBottomNav.handleTab('spaces') and MobileSpacesScreen's initial
useState now resolve via `currentSpaceId ?? lastSelectedSpaceId`. The
prior Object.keys(lastChannelPerSpace)[0] fallback was wrong twice over:
first-inserted ordering locked the tab to whichever space the user
opened first in their session, and any approach reading currentSpaceId
alone breaks after a /channels/@me detour.
Also fixes a pre-existing render loop in MobileSpacesScreen's
currentSpaceId sync effect — `selectedSpaceId` removed from deps,
functional setState makes the update idempotent.
Spec: docs/systems/mobile-ui.md updates Tab Tap Behavior, MobileScreenHeader,
and LocalStorage Persistence sections.
iOS Safari auto-zooms (and shifts the viewport right) on focus when the
computed font-size is <16px. Single @media (max-width: 767px) block in
globals.css covers all four input tiers, every relevant bare <input>
type, <textarea>, <select>, and contenteditable surfaces. `!important`
is required because Tailwind utilities (text-[15px] on the chat composer,
text-sm on form fields) emit after @layer components and would otherwise
override the input-tier rules.
Replaces ad-hoc per-input `text-base md:text-sm` overrides with a single
global truth. New inputs/contenteditables get the fix for free.
Spec: docs/systems/design-system.md gains an "iOS Auto-Zoom Suppression"
section under Input Tiers.
