Private messages (NIP-17) arrived in the foreground with no signal: no
unread count, no badge, no OS notification. Hook both into the single
InboxService.ingest choke point.
- UnreadService: per-peer "last read" in the keystore (timestamps+pubkey
only, no message text), live count via a changes stream, active-peer
suppression so the open chat never badges or notifies.
- UnreadBadge: reusable, RTL-aware (Flutter Badge) — on the home hamburger,
the drawer "Chat" item, and per-conversation in the messages list.
- Mark-read on chat open (ChatScreen).
- NotificationService over flutter_local_notifications: generic
"New message from <name>" (no message text, for privacy), payload = pubkey,
tap opens /chat/:pubkey. No-op on web/Windows; Android POST_NOTIFICATIONS.
- i18n notifications.newMessageFrom (en/es/pt/ast).
Background/push stays out of scope (foreground-only by design).
Tests: UnreadService, NotificationService (mock plugin), InboxService hooks
(new peer notifies/counts; duplicate, own, and open-chat do not), and a
UnreadBadge widget test. dart analyze clean; commons_core green.
Reception only ran inside an open ChatScreen for a known peer, so a first
message from a new peer was invisible: nothing in local storage -> nothing
in the inbox list -> you never opened the chat -> you never subscribed.
Add InboxService: one long-lived NIP-17 inbox subscription for the whole
app (foreground), persisting every incoming message to MessageStore and
firing a 'changes' signal the inbox list live-reloads on. Reconnects when
the network returns; degrades to nothing offline. Started from main when a
social identity exists.
Make MessageStore.append idempotent (dedup by sender+timestamp+text) and
serialized behind a write lock — the global listener and an open chat's own
subscription now write the same conversation concurrently and relays
re-deliver stored gift wraps on every resubscribe. Tests for both.
Known trade-offs (follow-ups): foreground-only (no push yet); each of
InboxService/ChatScreen/MarketScreen opens its own RelayPool (a shared
connection is a later optimization).
