computePermissions() returned the space @everyone role's permissions without
verifying the caller had joined the space. Because CREATE_INVITE is in
DEFAULT_EVERYONE_PERMISSIONS, any authenticated user could mint an invite code
for a request-only space — whose id is listed by /api/spaces/explore — and then
self-join via /api/spaces/:id/join, bypassing the join-request approval flow.
The same gap let non-members read message history and search default channels.
Root cause:
- computePermissions now returns 0n for non-members (space owner and instance
admin still short-circuit first, so they are unaffected).
Defense in depth (request-only spaces are approval-gated, never invite-joinable):
- both invite-code join endpoints reject visibility='request' (private stays
invite-joinable — its only entry path; public too).
- POST /api/spaces/:id/invite refuses to hand out a code for request spaces.
- POST /api/dm/space-invite refuses to card a local request space, checked by
space id against the local table so a spoofed spaceInstanceOrigin can't slip
past it.
- InviteModal hides the invite affordances for request spaces.
Also removes the unused computeCategoryPermissions(), which duplicated the
resolution algorithm without the membership gate.
Adds unit + route + component tests covering non-member/member/owner/admin
resolution and the request/private/public visibility matrix.

Make Backspace self-hostable in any homelab environment, not just a clean host
that owns ports 80/443.
install.sh is now mode-aware and auto-detects which fits:
- allinone (default): bundled Caddy + auto-HTTPS — unchanged behavior
- proxy: behind your own reverse proxy (nginx / Traefik / Caddy / Nginx Proxy
Manager / SWAG) — app published on 127.0.0.1:APP_PORT, no bundled Caddy,
prints paste-ready proxy snippets
- tunnel: behind a tunnel (Cloudflare / Tailscale) — same, plus a 90MB upload
cap (under Cloudflare's 100MB body limit) and voice force-disabled (WebRTC
over UDP can't traverse a tunnel)
Port detection is Docker-aware (consults `docker ps` published ports, not just
`ss`), so a host whose proxy already owns 80/443 via iptables DNAT — with no
listening socket for `ss` to see — is correctly detected as "taken" instead of
dead-ending.
docker-compose.proxy.yml is a small overlay, layered via COMPOSE_FILE (written
into .env so no `-f` flags are ever needed), that publishes the loopback port and
parks Caddy in an inert profile. The base compose file is untouched, so All-in-One
behaves exactly as before.
Prebuilt image: .github/workflows/docker-publish.yml builds and pushes a
multi-arch (linux/amd64 + linux/arm64) image to ghcr.io/thezwiss/backspace on
release tags (and manual dispatch), so weak/ARM hosts skip the ~1.6GB local build
(the Vite build OOMs small ARM boxes). install.sh and docker-compose.yml default
to pulling it, fall back to an image already present on the host, and finally to a
from-source build — AGPL §13 commit stamping preserved on every path. Kept
deliberately separate from the desktop-installer workflow (release.yml).
Docs: README gains a "Deployment modes" section (all three modes, nginx / Caddy /
Traefik snippets, GUI-proxy field-by-field, cloudflared ingress, the update path,
and voice-per-mode caveats); docs/systems/deployment.md updated to match.
Verified live on a throwaway VM: proxy + all-in-one end-to-end through install.sh
(with a real Let's Encrypt cert), tunnel config generation, loopback-only binding,
and the local-image fallback path.
A reset peer reaches needs_attention via the auth-failure path (HMAC desynced by
the new incarnation) without passing through unreachable, so the 5s recovery
probe never saw it — detection waited up to a full 15-min health-check cycle
before 'Re-peer & heal' surfaced. Extract detectResetForPeer() and fire it
event-driven at the transition, plus a startup sweep for already-stuck peers.
15-min tick remains the backstop.
Finding 1: handleReactionAdd/Remove now drop reactions on a dead 1-on-1
(isDeadOneOnOne) — previously a survivor could react on a Deleted-User
thread and the relay fanned out to all peers via undefined target-origins.
Client Message.tsx withdraws add/toggle reaction affordances for dead DMs
(existing reactions still display read-only).
Finding 2: dmMembership purge test now runs with foreign_keys=ON (matches
prod) and asserts dm_members/dm_messages cascade cleanup on channel purge.
Finding 3: tombstone group-DM ownership transfer filters isDeleted=0 so
ownership can never move to a tombstoned member; covered by a new test.
A reset peer can reach needs_attention via the auth-failure path (HTTP up,
401/403 from a new incarnation crossing AUTH_FAILURE_THRESHOLD) without ever
passing through unreachable, so the unreachable-only recovery probe never
observes its epoch change and no reset journal is created — leaving a later
manual Re-peer with nothing to heal.
Add detectResetOnNeedsAttentionPeers() to the 15-minute health-check tick:
probe needs_attention peers with a non-null baseline (excluding those already
peer_reset_detected) and call markPeerReset on an observed epoch mismatch.
Detection only — never recovers a needs_attention peer to active; baseline
(peer_instance_id) and hmac_secret untouched.
Add healResetIncarnation (federationReset.ts): fires from onPeerActivated after
an authenticated re-peer to soft-tombstone the flagged pure S2S stubs of a reset
peer's dead incarnation, clearing stale friendships/DMs so the reported bug is
fixed. Two mandatory guards: a reason gate (allow-list of 8 genuine handshake
activation reasons; excludes health_check_recovery + startup_bootstrap so their
stale baseline can never silently resolve a journal without healing) and an
epoch comparison (dead_epoch === newEpoch => false alarm, no tombstone). Uses
tombstoneUser(uid, { purgeContent: false }); real federated accounts are left
flagged + intact for Phase 2. Runs outside any transaction. Wire into
onPeerActivated before the mutation-log re-sync.
Two mirror-image bugs from voice/DM-call transitions leaving stale state.
DM call → space channel (stuck "Connecting…"):
The last participant to leave a DM call for a space channel receives a
`dm_call_ended` echo (server empties the DM room on their `voice_join`).
The handlers called `disconnectFn()` unconditionally, tearing down the
space room they had just connected to. Route `dm_call_ended` /
`dm_call_rejected` / terminal `dm_call_undeliverable` through a new
`teardownDmCall()` that only disconnects LiveKit when not in a space
channel (`currentVoiceChannelId` null).
Space channel → DM call (still shown as "in" the voice channel):
1. Entering a DM call never cleared `currentVoiceChannelId`, so
`VoiceChannel` mapped the DM call's live LiveKit participants onto the
old space channel. Add `clearSpaceVoiceForDmCall()`, called in
`connect()` when `isDm`, restoring the invariant that a DM call has no
`currentVoiceChannelId`.
2. `dm_call_accepted` gated the caller's connect on `!isLiveKitConnected`,
so a caller already in a space channel was never connected to the DM
room. Gate on `wasOutgoingCall` only (connect() de-dupes same-room).
Tests: teardownDmCall.test.ts, clearSpaceVoiceForDmCall.test.ts.

Replace the placeholder Screenshots section with a hero voice/video shot
and a curated 6-shot grid (chat, screen-share controls, spaces, federated
DMs, social discovery, federation admin), linking to a new
docs/screenshots.md gallery of all 14 shots grouped by feature.
Images are optimized to 1600px WebP (~1.2MB total vs ~45MB raw); raw
originals in demo-pictures/ are gitignored.
The server's `playable` flag is computed Chromium-first, but HEVC
web-playability is browser-dependent: WebKit (Safari on macOS/iOS) decodes
HEVC via the OS while Chromium/Firefox/Electron can't. Treating the flag as
global wrongly showed Safari users the download fallback for files they can
play inline.
The client now treats `playable === false` as "needs a capability check": it
pre-renders the fallback only when the current browser also can't decode the
format, gated on a one-time canPlayType probe (BROWSER_SUPPORTS_HEVC). Capable
browsers attempt inline playback; the <video> onError handler remains the
safety net for genuine failures.
macOS screen recordings are HEVC inside a .mov container, which Chromium,
Firefox and stock Electron can't decode. The file uploaded fine and a
server-side ffmpeg poster was generated, but inline <video> playback failed
silently — stuck at 0:00 with no error, since AttachmentRenderer had no error
handling. Root cause: the system had no concept of web-playability.
Server detects, client degrades:
- mediaPlayable.ts: classifyVideoPlayable(mimetype, codec) — tri-state
(false = known-undecodable e.g. HEVC/ProRes, true = web codec in web
container, null = unknown/optimistic). Never widens `false` beyond codecs
that fail everywhere, so ffmpeg-less instances keep prior behaviour.
- probeMediaMeta now captures the video codec_name; the upload finish hook
stores the verdict in the new attachments.playable column (migration 0007).
- Flag propagated through every serializer: space messages, DMs, WS, and
federation relay (outbound + inbound) — federation-compatible.
- VideoAttachment component: playable===false renders a download card (poster
+ "Can't play here — download" + name/duration/size) with no dead-player
flash; otherwise plays inline with an onError fallback to the same card.
Specs updated: uploads.md, database.md, federation.md.
Voice presence (voiceStates/voiceUserStates/spaceVoiceStates) was only ever
delivered in the WS `ready` payload — i.e. at connect/reload. A user joining a
space mid-session got `member_joined` (no voice data) and a bare space object;
`GET /api/spaces/:id` (the channel-sidebar hydrator) carries no voice state
either. So members already sitting in a voice channel stayed invisible in the
new member's sidebar until a full page reload.
Fix at the systemic root: ConnectionManager.addUserSpace — the single chokepoint
every join path funnels through (invite, public join, join-request approval),
and which is NOT used on reconnect (that path uses setUserSpaces) — now pushes a
scoped `space_voice_state` snapshot to the joining user. The snapshot is built by
a new buildSpaceVoiceState(spaceId, userId) helper that is also the single source
of truth feeding buildReadyPayload (refactored to use it), so the connect-time
and join-time paths can never drift.
Robustness:
- Delivered over the same ordered WebSocket as voice_state_update deltas — no
REST snapshot-vs-event-stream race.
- VIEW_CHANNEL-filtered via computePermissions exactly like `ready`: a joiner is
never told who occupies a voice channel they cannot see.
- Client applies it scoped to the space (utils/voiceStateSync.applySpaceVoiceState):
merges occupants/statuses and rebuilds only that space's restriction keys,
never disturbing voice state in other spaces.
- Skipped when the space has no active voice and no restrictions (e.g. space
creation).
Tests: server helper behavior, the join push, and private-channel exclusion;
client scoped-apply. Specs updated (websocket.md, voice.md, spaces.md).
The sidebar's visibleChannels filter is keyed on the channelPermissions
Map. Creating a channel raced two state updates: the optimistic create
(added to channels with no permission entry) and the channel_created WS
event (the only thing that set the permission). When the optimistic add
won the race, the WS handler hit its dedup guard, skipped setChannels,
and set the permission by mutating the Map in place — no new reference,
so visibleChannels never recomputed and the channel stayed hidden until
loadSpace rebuilt the maps (i.e. leaving and returning to the space).
Centralize the logic in a new upsertChannel store action that replaces
channels and channelPermissions with fresh references, used by both the
create path and the channel_created handler. Also return the creator's
computed myPermissions (and isPrivate) from POST so the channel renders
immediately from the response, independent of WS timing.
Adds spaceStore.upsertChannel.test.ts covering the reference-identity
regression and the optimistic-reconcile path.
Replace ripped Discord audio with self-authored Ogg Vorbis files (avoids
copyright on open-source launch) and fix three cue bugs:
- Anti-pop envelope: playSound now applies a 10ms fade-in (+ tail fade-out
for one-shots) so buffers no longer start at a non-zero amplitude. Kills
the pop on the looping call cues. Mirrors playTestTone.
- Deafen no longer plays mute+deafen at once: toggleDeafen flips isMuted and
isDeafened atomically, so SoundController saw both transitions. New tested
pure helper selectVoiceStateSound() suppresses the side-effect mute cue.
- Viewer-side watch feedback: stream_user_joined/left now play locally on the
watcher's own machine for explicit Watch/Stop actions, via
handleViewerWatchToggle. Direct local playback (not a watchingStreams diff)
keeps auto-teardown silent and works identically on Safari and Electron.
Docs: docs/systems/sounds.md updated (Ogg, dual-audience cue rows, mute/deafen
selection, viewer feedback, anti-pop envelope).
Eliminates the visible push-down/snap-back when the pagination loading
skeleton appears at the top of the message list. Achieved by rendering a
constant-height (~200px) top-of-list slot above messages whenever
hasMore===true; the skeleton's grey-bar contents toggle inside that slot
rather than the slot itself mounting/unmounting. Companion changes:
load-more trigger raised to fire before the slot enters the viewport with
an iOS Safari rubber-band guard, prepend scroll-restore math corrected to
handle non-zero prevScrollTop, useDelayedLoading threshold lowered to
50ms for pagination only.
