- Keep max lastSeen per user so relay's newest-first delivery doesn't
overwrite a fresh timestamp with a stale one
- Serialize event processing on Main dispatcher to eliminate
ConcurrentModificationException on geohashParticipants maps
- Immediately refresh people list on channel switch so sampling data
is reflected before the first relay response arrives
This change prevents the app's content from being visible in the recents screen on Android 13 (Tiramisu) and newer devices.
It achieves this by calling `setRecentsScreenshotEnabled(false)` in the `onCreate` method of `MainActivity` after checking the device's SDK version. This enhances user privacy by hiding potentially sensitive information from the system's app overview.
When a URL contains a # fragment (e.g. https://example.com/page#section),
the hashtag regex matches the fragment as a hashtag. The overlap removal
logic already removes hashtags overlapping geohashes, and geohashes
overlapping URLs, but did not remove hashtags overlapping URLs. Add the
missing overlapsUrl check to the hashtag condition.
* Pause Nostr geohash firehose in background to cut mobile data
The Bluetooth mesh uses no mobile data, but the Nostr relay layer ran
unbounded in the background: the live geohash channel subscription kept
streaming across 5 relays, the presence heartbeat broadcast every ~60s,
and a participant-refresh timer polled every 30s. Combined with
reconnect/re-subscribe replay on public relays, this could burn gigabytes
while idle.
GeohashViewModel now tears down the high-volume subscriptions when the app
is backgrounded (onStop) and restores them on foreground (onStart):
- drop the live channel message stream (currentGeohashSubId)
- drop sampling subscriptions
- cancel the presence heartbeat and participant-refresh timer
Gift-wrap DM subscriptions are intentionally kept alive in the background
since they are filtered to our pubkey (lightweight) so DMs still arrive.
The selected channel is tracked in activeChannelGeohash so the stream can
be rebuilt on foreground without losing the user's selection. The channel
subscription logic is extracted into subscribeChannelStream() /
subscribeChannelDM() helpers.

* fix(sync): resolve hash alignment and early break bugs on GCS filter trimming
* fix(sync): filter out zero bucket and deduplicate buckets before encoding
* fix(sync): preserve zero-bucket mapping by clamping 0 to 1 during encoding and decoding
* fix: add input validation for protocol decoding and fragment reassembly
* fix:subtract the old entry's size before adding the new one, so duplicate/retransmitted fragments don't inflate the counter
* fix: FragmentManager.handleFragment() can be entered concurrently (e.g., fragments for the same fragmentID arriving from multiple peers/relays). In order for this to happen multiple devices would be needed to connect to the mesh. even with a per-fragmentID byte cap, an attacker could open many fragment IDs at once and force the device to buffer lots of fragment data overall (risking memory pressure/OOM). In this fix we made fragments atomic and thread safe. When a fragment index is retransmitted, we compute the size delta (new - old) so duplicates don’t inflate counters and can’t be used to bypass limits. Under heavy load/attack the app will drop/reject fragment sets earlier instead of growing memory usage without bound to reduce risk of oom. tested on pixel 6 and pixel 8.
* fix: add fragmenttest
* Add 'Send private message' action to chat user sheet
* Change 'Send private message' action color to purple
