populateFromReady() built the federatedId dedup set from ALL existing
DMs, including those belonging to the reconnecting origin. Incoming DMs
then matched their own stale entries and were skipped as "duplicates."
The subsequent origin-removal step deleted the old copies, leaving no
DMs from that origin in state.
Scope the dedup set to DMs from OTHER origins only, so reconnecting
origins replace their DMs cleanly while cross-instance dedup still works.
Three bugs that combined to corrupt DM identities during initial sync:
1. Sync endpoint omitted federatedId for group DMs, causing the receiver
to treat them as 1-on-1 DMs and compute wrong pair hashes — creating
phantom channels that collide with real ones.
2. backfillHomeUserId unconditionally overwrote existing homeUserIds,
so a single wrong match would permanently corrupt a user's identity
and cascade to all subsequent lookups.
3. Migration duplicate-stub Criterion 1 ("shared 1-on-1 DM membership")
incorrectly merged different users from the same domain who were
simply having a conversation, destroying one user's identity.
The relay broadcast loop skipped members whose homeInstance matched the
source instance, assuming they already received the message on their home
server. This broke delivery for federated users (e.g. youruser@nova on
orbit) who are actively connected to the remote instance.
Client-side dedup in addRealtimeMessage already handles double delivery
via sourceMessageId cross-matching, making the server-side skip both
unnecessary and harmful.
Add federation.md section 8b covering dm_close/dm_reopen relay events:
payload, outbound queueing via queueDmCloseRelay, inbound processDmCloseEvent/
processDmReopenEvent handlers (lookup-only identity resolution, silent
no-ops on missing channel/user/membership), and the processCreateEvent
closed-state reopen bug fix.
Update dm-system.md soft-close section with federation behaviour: relay
to peers for both close and reopen, relayed-message reopen in
processCreateEvent, and the federatedId-only guard for legacy DMs.
Queue dm_close relay in DELETE /api/dm/:id after broadcasting locally,
and queue dm_reopen relay inside the myDm.closed === 1 branch of POST
/api/dm so peers are notified only on actual reopen, not new DM creation.
When a federated user first accesses DMs on a remote instance,
all channels appear unread because no read_states rows exist.
Seed missing read states to the latest message during the ready
payload build. The S2S relay keeps things in sync going forward.
Remove home-only restriction on DM events. Add federatedId
dedup check to dm_channel_created to prevent duplicate sidebar
entries for cross-instance DMs.
Replace home-only DM filter with unified DM list. DMs from all
connected instances are merged, deduplicated by federatedId.
First-loaded copy wins; both copies are in sync via S2S relay.
Receive read_state_update events from peers, translate message
coordinates to local IDs via sourceInstance/sourceMessageId
mapping, update read_states with timestamp-only LWW.
Queue read_state_update events when users ack DM messages on
channels with a federatedId. Translates local message IDs to
federation coordinates using sourceInstance/sourceMessageId.
Artworks, .claude, .worktrees, .playwright-mcp, docs/internal,
design prototype, and architecture audit are dev-only — no need
on production servers. packages/desktop was already excluded but
stale copies persisted on remotes.
profileUpdatedAt ?? createdAt treated freshly registered users as having
"newer" profiles than users with real edit history, because createdAt is
always NOW at registration time. This broke federation profile sync:
the client correctly pushed home → remote, but the remote server's LWW
guard rejected the write (stored createdAt > incoming profileUpdatedAt).
A null profileUpdatedAt means "never edited" — that's timestamp 0, not
the user's creation time.
After deleting a federated identity, the server-side user_federation_registry
and users.replicated_instances were not cleaned up, causing "already connected"
errors when trying to re-federate. The deletion endpoint now authoritatively
removes both the registry row and the replicatedInstances entry, and bumps the
LWW timestamp to prevent stale client syncs from re-inserting them.
Also extends the endpoint to accept mode 'leave' (skip S2S, just clean up),
and enables the "Select instances..." scope option in DeleteIdentityDialog.
Add removeRequestsForUser (socialStore), removeUser (discoverStore), and
clearTypingForUser (chatStore) to support isDeleted cleanup in the
user_updated WS handler.
Switch from manual space-ID collection to collectDeletionBroadcastTargets and
add user_updated broadcast so clients patch their caches when a federated user
is deleted via S2S. Force-disconnect moved after broadcasts so other tabs
receive events before the connection is torn down.
- Orphaned DM channels (zero members) are unreachable garbage — clean
them up regardless of purgeContent mode, not just in full/nuke mode.
- Full/nuke mode now also deletes the user's space messages, their
attachments, and embeds. This is the meaningful distinction: "Delete
User" preserves all content as "Deleted User", "Nuke" removes it.
After a prior deletion + re-federation, multiple user records share
the same homeUserId (one deleted, one live). The unfiltered .get()
returned the older deleted record, causing the idempotency check to
short-circuit and miss the live record entirely.
Update the dialog to support three deletion modes (leave/soft/full),
scope selector with disabled "Select instances..." option, loading
state during deletion, and per-instance error handling via toasts.
When a federated user's identity has been tombstoned (isDeleted=1),
findFederatedUser filters them out, causing resolveOrCreateReplicatedUser
to silently create a new stub — a "zombie" resurrection. This guard checks
for a deleted row before creating a stub and returns null instead.
All 11 call sites across federation.ts and dm.ts have been updated with
appropriate null guards: federation relay handlers reject or skip the event
(participant_not_found / accepted no-op), while dm.ts routes convert null
to undefined so the existing 404 path handles it.
The modal read from the global spaceStore.members which only contains
members for the currently active space. Opening the modal via right-click
context menu on a space that hasn't been navigated to yet resulted in an
empty member list. Now fetches members independently via the dedicated
GET /api/spaces/:id/members endpoint with federation-aware API routing.
The modal was manually rendering avatars with a static bg-surface-input
background, bypassing the Avatar component's getAvatarGradient() logic.
Users without profile pictures got blank dark circles instead of their
hash-generated or user-set avatar color gradients.
- Remove tinted description box, use plain text
- Buttons are now flex-1 equal width side by side
- Cancel gets visible bg-interactive-hover background
- Larger padding, rounded-xl, wider max-w
- FriendItem/RequestItem: add plain wrapper div so divide-y border
lands on a non-rounded element (fixes curved separator lines)
- Add border-t to divide-y containers so first row also gets top line
- Remove uppercase from "Direct Messages" in DM sidebar
Add third group for instances the user explicitly disconnected via
the registry. These get a disconnected placeholder with preserved
token for instant reconnect, but no auto-connect on page load.
Aligns the ready payload query with the GET /api/dm approach:
get MAX(created_at) per channel first, then fetch the actual
message rows. Avoids issues with federated relay messages whose
local snowflake IDs don't match chronological order.
Extracts the inline DM list item rendering (~105 lines) from
ChannelSidebar.tsx into a standalone component. Applies cohesive
hover states, 6px border radius, 44px row height, and a selected-
state accent bar matching ChannelItem's pattern.
When the same person registers on multiple federated instances, separate
DM channels are created for each identity, causing duplicate sidebar
entries (e.g., "Nova" appearing twice — once for local, once for
federated account).
Add deduplicateDmChannels() safety net that detects matching counterparts
using two layers: canonicalUserMatch (same ID/homeUserId/username) and
replicatedInstances cross-check (local user has a replicated account on
the federated user's home instance with the same base username). Keeps
the DM with the most recent activity, applied in both setDmChannels and
populateFromReady.
Investigation: queried both live instances (nova.ddns.net, orbit)
and confirmed root cause is same-person-two-accounts, not a server-side
creation bug or identity resolution gap.
Introduces a lightweight DmLastMessagePreview interface for the ready
payload and GET /api/dm response, and widens DmChannel.lastMessage to
accept either DmLastMessagePreview or DmMessageWithUser so both the
static preview path and real-time WS events can coexist without casts.
- disconnectInstance: save cached tokens BEFORE filtering the instance out, so
reconnectInstance can restore disconnected entries from localStorage
- reconnectInstance: if instance is not in active instances array, attempt to
restore it from cached localStorage token before proceeding with reconnect
- reconnectInstance: update registry to unreachable/auth_expired on failure
- forceRemoveEntry: now tears down WS, removes from instances array, purges
token from localStorage, and cleans up space store (was registry-only before)
Adds persistent federation registry storage endpoints under
/api/users/@me/federation-registry. GET returns all registry entries
with the stored updatedAt timestamp. PUT replaces the full registry via
LWW (409 on stale write) in an atomic transaction.
