* Location notes: Matrix loader with 1–3s minimum display; allow multiple notes; wire notes UI from mesh toolbar
* Location notes: prevent duplicate loading/subscriptions (StateObject manager, geohash captured at open, guard subscribe)
* Location notes: fix duplicate state redeclaration in ContentView
* Location notes: render note bodies with monospaced font in notes list
* Location notes: add close (x) button in sheet header (upper-right) using @Environment(\.dismiss)
* Location notes: acquire geohash on open (force refresh) and show Matrix loader until block-level geohash resolves; add LocationNotesSheet wrapper
* Location notes: inline sheet wrapper to avoid missing file in target; force location refresh and show Matrix loader until block geohash resolves
* Location notes: remove Matrix animation; use simple spinner when acquiring location; simplify notes view layout
* Location notes: remove per-note relative timestamp from sheet (no seconds display)
* Location notes: fix intermittent first load by ensuring resubscribe after geohash change, removing over-eager subscribe guard, and widening note fetch window (no since filter)
* Location notes: add background counter service and show count next to notes icon on mesh; auto-subscribe to current block geohash
* Location notes: move notes icon to the right of #mesh badge in toolbar
* Location notes: restore timestamps in notes list; remove loading state from manager and sheet (no spinner/animation)
* Location notes: drop 'teleport' tag from kind-1 events; simplify note builder API and usage
* Location notes: show timestamp as relative within 7 days, else absolute date (MMM d or MMM d, y); keep monospaced styling
* Location notes: append 'ago' to relative timestamps (within 7 days)
* Switch location notes and UI helpers to building-level geohash (precision 8): add GeohashChannelLevel.building, map length 8, use building for notes selection and counter, add building name mapping
* Location notes: change notes toolbar icon to SF Symbol 'long.text.page.and.pencil'
* Revert notes geohash selection back to block-level (precision 7); keep building level available but unused; update counter and sheet accordingly
* Location notes: show block name (from reverse geocode) in header instead of 'street-level notes'
* Nostr: add EOSE handling with callback support for subscriptions; wire to LocationNotesManager/Counter (initialLoadComplete). Remove 'building' level from channel enum and geocoder mapping; geohash list shows block/neighborhood/city/province/region only
* Fix Swift 6 isolation: hop to @MainActor inside Timer callback for EOSE tracker mutations
* Notes counter: show 0 by default; subscribe at building-level (precision 8) for notes and counter; keep building hidden in channel list
* Notes header: show building name when available (fallback to block name)
* Notes: subscribe counter to building + parent block (merge results); hide notes icon unless location is authorized; replace 10s timer with live location updates while sheet open
* Notes counter: subscribe only to building geohash (precision 8) so count reflects current 8-cell; auto-begin live location refresh on mesh (and permission) to update as you walk
* Notes header: show count in parentheses; icon shows blue if any notes, grey if none; only start live location updates while sheet is open; reduce nickname width; set live distance filter to 10m
* Notes header: show count as '(N note/notes)' with non-bold, secondary styling next to title
* Notes header: move count before title as '<N> note(s) @ #gh'; remove parentheses; keep count non-bold
* Notes header: bold count text; ensure sheet updates when building geohash changes by calling manager.setGeohash on geohash change
* Notes sheet: add light haptic feedback when building geohash changes (iOS only)
* Notes icon: force a one-shot location refresh before (re)subscribing the counter so icon turns blue immediately on current 8-cell
* Notes subscribe: fallback to default relays when GeoRelayDirectory has no entries (pass nil relayUrls) so counter/icon turn blue and sheet loads even before georelay fetch
* Notes icon: turn blue immediately when sheet shows notes by passing count up from sheet (closure) and OR-ing with counter; reset on sheet close

* Fix emote targeting and grammar; add tests
Prevent 'system' mis-target via peerID-derived display name in actions sheet. Correct /hug and /slap usage/error grammar by passing base command name. Improve geohash nickname resolution to match displayName with #suffix. Add CommandProcessor tests.
* Geohash ordering: strict in-order inserts and timestamp clamp
Use channel-aware late-insert threshold with 0s for geohash to keep strict chronological order. Clamp future Nostr event timestamps to 'now' to avoid future-dated items skewing order in geohash timelines.
* Trim trailing/leading spaces in geohash nicknames and tag emission
Sanitize Nostr 'n' tag values on ingest and emit by trimming whitespace/newlines to prevent trailing spaces in displayed usernames. Local nickname is already trimmed on focus loss and submit.

* Add geohash bookmarks: persistence, sampling integration, and UI\n\n- Add GeohashBookmarksStore with UserDefaults persistence and toggle API\n- Sample union of regional + bookmarked geohashes for activity notifications\n- LocationChannelsSheet: bookmark icons on nearby rows and a Bookmarked section\n- Header toolbar: toggle bookmark for current geohash\n- Tests: GeohashBookmarksStoreTests for normalization and persistence\n\nRationale: Bookmarked geohashes are always sampled for new activity notifications and quickly selectable from the sheet.
* Notifications: remove background 'new chats!' nudge; geohash activity only on zero→alive; mesh 'nearby' only on zero→alive\n\n- Geohash sampling: notify only when previous participant count in last 5m was zero, with 30s freshness gate\n- Suppress old sampled events after (re)subscribe\n- Remove channel inactivity nudge\n- Mesh: reset rising-edge gate immediately when peer list goes empty (strict zero→alive)
* Geohash notifications: ensure triggering message appears\n\n- On zero→alive sampling, pre-populate geoTimelines[gh] with the triggering message\n- Dedup on per-geohash timeline and UI messages by message ID to avoid duplicates after subscribe\n- Keeps participant update, block/self checks, and cooldown intact

- Use minimal-distance hue palette for mesh and geohash lists; align chat sender colors with list palette.
- Add foreground geo notifications for different channels; deep-link to bitchat://geohash/<gh>; per-geohash 60s cooldown; respect self/blocks.
- Global geohash sampling runs outside the sheet; delegate handles deeplinks and suppresses when already in-channel.
- Switch location channel sheet to continuous CoreLocation with 21m distance filter; add config knob.
- Only link geohash hashtags when standalone (no @name#abcd or word#abcd).
- Include mesh-reachable peers in mesh counts and in "bitchatters nearby" notification.
- Add TransportConfig knobs for palette and geo notifications.

* Sign public broadcasts; verify relayed messages via persisted signing keys; keep scheduled relays in sparse graphs and speed their jitter; persist announce signing key for offline auth; add short backoff after disconnect errors to reduce reconnect thrash
* Add connected vs reachable model: retain peers after link drop, expire after reachability window; expose all peers in snapshots; compute isReachable in UI; add meshReachable state and sorting; avoid removing peers on link events; notify UI on stale removals
* ContentView: handle new .meshReachable connection state in header icon switch (exhaustive switch fix)
* Logs: tag relayed announces as 'Reachable via mesh' and annotate public message logs with (direct|mesh) path for easier field analysis
* Fix syntax error: remove stray else/log inserted into writeOrEnqueue; keep logs clean
* UI: use 'point.3.connected.trianglepath.dotted' for mesh-reachable; change people count to include connected+reachable (exclude Nostr-only)
* UI: switch to 'point.3.filled.connected.trianglepath.dotted' for mesh-reachable icons in list and header
* Reachability: reduce retention to 21s for all peers (verified and unverified) to minimize stale presence
* mesh DMs/acks: route to reachable peers; queue READ/DELIVERED until handshake; add Transport.isPeerReachable; UI: hide offline non-mutuals; DM header: better name fallback + show transport + encryption icons; fix NostrTransport conformance
* Verification sheet: compute encryption status and fingerprint using short mesh ID mapping (fix 'not encrypted/handshake' for DMs with stable key)
* Announce cadence: faster discovery (4s), sparse 15±4s, dense 30±8s; initial 0.6s; post-subscribe 50ms; min-force 150ms; maintenance 5s; proactive announces on handshake + recent-traffic nudge
* Relay: increase broadcast TTL cap in sparse graphs to 6; tighten jitter for handshake (10–35ms) and directed (20–60ms) relays
* Range/robustness: store-and-forward for directed packets (15s) with flush on new links + periodic; announces: no subset + afterglow re-announce on first-seen; adaptive scanning: force ON when <=2 neighbors or recent traffic
* Fix warnings: remove unused msgID and unused mutable var in directed spool flush
* Announces: TTL 7 (sparse only) via RelayController; no fanout subset for announces; neighbor-change rebroadcast of last 2–3 announces. Fragments: faster pacing (5ms global, 4ms directed).
* Peer list: real-time icon updates by publishing snapshots on connectivity checks; add unread message indicator (envelope) next to peers with unread DMs
* UI: unread envelope uses orange; hasUnreadMessages checks Nostr conv key for peers with known Nostr pubkeys (geohash DM consistency)
* Logs/robustness: debounce disconnect notifications (1.5s), debounce 'reconnected' logs (2s), add weak-link cooldown after timeouts on very weak RSSI (<= -90)
* Peer icons: faster, accurate reachability\n\n- Run connectivity checks every maintenance tick (5s)\n- Publish peer snapshots on central unsubscribe for instant UI refresh\n- Lower inactivity timeout to 8s and disconnect debounce to 0.9s\n- Gate reachability on mesh-attached (>=1 direct link); no links => no reachable peers\n- Keep 21s retention for verified/unverified, but only when attached to mesh\n\nImproves list responsiveness when walking out of range and prevents stale 'reachable' states when isolated.

* Fix geohash color mismatch: populate nostrKeyMapping before building messages in resubscribe; also honor t,teleport tag for teleported state
* Message actions: username tap opens sheet via clickable AttributedString; message tap inserts @mention; rename to 'direct message'
* Cashu UX: suppress 'Show more' when message contains a Cashu token (chips handle rendering)
* Cashu detection: broaden regex (allow '.') + shorter min length; avoid long-text fallback when Cashu present so chips render and no full blob

* Geohash peers: show face.dashed for self when channel selected via teleport; face.smiling otherwise
* Geo presence: broadcast 'teleport' tag on geochat join; track teleported participants and show face.dashed for them in peer list
* Teleport tag: attach to actual geohash chat events (sendMessage, emotes, screenshots) instead of separate presence; remove presence emit
* Fix: show face.dashed for any teleported peer (not just self) in geohash list

* Require signed announces; add Ed25519 key/signature/timestamp TLVs and verify
- Protocol: AnnouncementPacket now requires ed25519PublicKey (0x03), announceSignature (0x04), and announceTimestamp (0x05). Encoder emits, decoder requires; unknown TLVs still tolerated.
- NoiseEncryptionService: add canonical announce sign/verify helpers using context 'bitchat-announce-v1'.
- BLEService: sign Announce, include TLVs; on receive verify (±5 min skew) and ignore unverified; store ed25519 key and isVerifiedNickname in PeerInfo.
- Preserve 8-byte on-wire IDs to keep BLE headers small; no per-message bloat.
* Fix Data.append usage for timestamp bytes in Packets and NoiseEncryptionService (use append(contentsOf:) on UnsafeRawBufferPointer)
* BLEService: fix non-optional announce fields and unwrap signature result; enforce required verification path
* Enforce verified-only public messages; append peerID suffix on nickname collisions in handleMessage
* Suffix duplicate nicknames with peerID prefix in snapshots and getPeerNicknames; ensures lists and messages disambiguate 'jack' vs 'jack'
* Include self nickname in collision detection: suffix remote 'jack' when it matches our nickname in lists and public chat
* UI labels: remove space before '#abcd' suffix in names (public chat, peer lists, snapshots)
* Style '#abcd' suffix light gray:
- Public chat: color suffix in sender via AttributedString segments
- People list: split name and color suffix segment; add helper splitNameSuffix()
* Debounce 'bitchatters nearby' notification: add 60s grace before reset when mesh goes empty; cancel reset when peers return
* Lighten '#abcd' suffix: use Color.secondary.opacity(0.6) in public chat sender and People list
* Toolbar peers indicator: use blue when Bluetooth peers present (was default text color)
* Toolbar peers indicator: use grey when zero peers (was red)
* Toolbar peers indicator: use system grey (Color.secondary) when zero peers, not green
* Fix crash: mutate peripherals dict on BLE queue (not main). Move scan restart to BLE queue as well.
* Reduce connect timeout churn: back off peripherals that time out (15s), increase timeout to 8s, skip non-connectable adverts, and demote timeout log to debug; clean backoff map periodically
* Mentions: support '@name#abcd' disambiguation; filter hashtag/URL styling inside mentions; deliver notifications only to the specified suffixed target when collisions exist
* Fix string interpolation in mention log (escape sequence)
* Mentions: parse '@name#abcd' in sender/receiver; render mention suffix grey (not orange/blue/underlined); ensure receiver notifications trigger for suffixed tokens
* Mentions: include own suffixed token 'name#<myIDprefix>' in valid tokens so '@name#abcd' to self is recognized and notified
* Public actions: show own system message by processing own public messages (remove early-return). Private /hug: add local system message for sender's chat.
* Grammar: change local '/hug' message to past tense ('you hugged/slapped'). Notifications: only fire 'bitchatters nearby' on rising-edge; remove 5-min re-fire and increase empty reset grace to 10m.
* Public /hug echo: add local system message so sender sees action immediately (no reliance on echo)
* Fix visibility: expose addPublicSystemMessage on ChatViewModel and use it from CommandProcessor
* Implement iOS Location Channels (geohash public chats)
- Domain: add ChannelID, GeohashChannel(Level), lightweight geohash encoder
- Identity: derive per-geohash Nostr keys (HMAC-SHA256 device seed)
- Nostr: kind 20000 + #g tag, nickname tag (n), filter helper
- iOS: LocationChannelManager (permissions, one-shot location), Info.plist string
- UI: toolbar # badge (#mesh or #<level>), sheet (irc style, full-row taps, settings link)
- VM: subscribe/send for active channel, clear timeline on switch, nickname cache
- Emotes: route public via Nostr/mesh without echo, local system confirmation, emojis restored
- Haptics: detect hugs/slaps for nickname#abcd and trigger on receiver
- Rendering: remove hashtag/mention formatting (plain monospaced)
Note: iOS-only; macOS unaffected.
* Lifecycle and persistence: resubscribe on foreground/relay connect, cap dedup set, persist mesh timeline.
- ChatViewModel: resubscribe geohash on app foreground and relay reconnect
- Add processed Nostr events cap (2k) with eviction
- Persist mesh public messages in meshTimeline; hydrate on switching to #mesh
- Local geochat messages use nostr: senderPeerID for classification
- Tests: fix JSON contains assertion for #g tag
* Fix Swift 6 concurrency warnings: remove closure-based NC observer, wrap relay reconnect resubscribe in Task @MainActor, resubscribe in appDidBecomeActive selector.
* Location Channels polish: live geohash refresh while sheet open; keep selection stable; toolbar shows #<geohash>; sheet labels show human level + #geohash.
* Add per-geohash in-memory timelines and cap private chats to 1337.
- ChatViewModel: persist geohash messages in geoTimelines[geohash] with cap; hydrate timeline on channel switch
- PrivateChatManager: trim per-peer chats to 1337 on send/receive
- Toolbar badge: prevent wrapping with lineLimit(1)/truncation
* Toolbar badge layout + brand color; Teleport custom geohash; Live refresh uses startUpdatingLocation with significant distance.
- Toolbar: right-justify geohash, head truncation, use brand green
- Sheet: add #custom geohash textfield + join; keep minimal IRClike style
- Manager: startUpdatingLocation()/stopUpdatingLocation() with distanceFilter=250 while sheet is open
* Location sheet live updates: reduce distanceFilter to 21m for more frequent geohash refreshes while open.
* Toolbar badge spacing/width; Sheet: rename to #geohash and button 'teleport'.
- Move # label closer to peer count and widen to avoid truncation
- Change custom field placeholder to '#geohash' and action button to 'teleport' with monospaced font
* Sheet polish: style 'teleport' button with subtle background, disable until valid; prefix '#' label and placeholder 'geohash'; center + style 'remove location permission' and hide separators for these rows. Toolbar: adjust spacing/width for # label.
* Sheet UX: restrict custom geohash input to valid base32 (lowercase, max 12), reduce spacing so placeholder sits closer to '#', add divider under country row, style 'remove permission' and hide row separators as before. Toolbar: minor spacing/width already adjusted.
* Sheet behavior: show channel list even without permission; add green 'get location and my geohash' button; ensure only one separator between country and teleport by removing manual Divider and showing default row separator; refine teleport input filtering and spacing.
* Channel activity nudges: notify after 9 minutes inactivity only in background; triple-tap clear also clears persistent timelines.
- ChatViewModel: track last activity per channel; send local notification when new activity resumes while app in background (with small cooldown)
- CommandProcessor: /clear clears current public channel persistence via viewModel helper
* Fix compile: add activeChannelDisplayName() and clearCurrentPublicTimeline() helpers in ChatViewModel.
* Fix concurrent dictionary access in BLEService.broadcastPacket: snapshot shared collections under collectionsQueue to avoid CocoaDictionary iterator crashes.
* People: channel-aware list and counts
- Sidebar: NETWORK → PEOPLE; removed PEOPLE subheader/icon
- Toolbar: blue #mesh badge; green #<geohash> badge; count color by channel
- Geohash participants: track per-geohash unique senders with 5m decay; publish list
- Update on geohash send/receive; 30s prune timer; channel switch hooks
No changes to mesh peer UX; mesh list retained as-is.
* BLE: snapshot collections for thread-safe access; stopServices uses snapshot; safe characteristic snapshot in broadcast path
LocationChannelsSheet: rename button label to 'remove location access'
* Channel sheet: show current peer counts
- Mesh row shows connected mesh peers count
- Geohash rows show 5m-active participant counts via ViewModel
- Live-updates while sheet is open
* Channel sheet: pluralize counts as 'person/people' in titles
* Geohash sampling: subscribe to all available channels while sheet open
- ViewModel: add multi-channel sampling subscriptions and per-geohash participant updates
- Sheet: start sampling on appear, sync on list changes, stop on disappear
* Channel sheet: render counts '(N person/people)' in smaller font next to label
* Channel sheet: use square brackets for counts and adjust parsing; fix mesh title to '#mesh'
* Geohash DMs: implement send/receive via NIP-17 with per-geohash identity
- NostrEmbeddedBitChat: add no-recipient encoder for geohash DMs
- NostrTransport: add sendPrivateMessageGeohash(using provided identity)
- ChatViewModel:
• startGeohashDM + mapping helpers
• subscribe to per-geohash gift wraps; store DMs in conversations keyed by 'nostr_<prefix>'
• route sendPrivateMessage() for 'nostr_' to Nostr geohash send; local echo and status
• map pubkeys from geohash public events for DM initiation
• resubscribe DM feed on reconnect and channel switch; unsubscribe on leave
- ContentView: long-press 'private message' starts geohash DM when sender is nostr
* Geohash DMs UX: tap participants to DM; support /msg nickname in geohash; DM notifications
- People (geohash) list: bold 'you', sort to top, tap to open DM
- ChatViewModel.getPeerIDForNickname resolves geohash names to nostr_ conv keys
- Geohash DM receive: send local notification when not viewing
* Geohash DMs polish: header title, star hidden, self-DM blocked, message icon, delivered/read ACKs
- Header shows '#<geohash>/@name#abcd' for geohash DMs; hide favorite star
- Geohash people row: add small message icon; prevent self tap
- Prevent sending geohash DM to self
- Send delivery/read ACKs on receive; handle delivered/read to update status
* Geohash DMs: hide encryption status icon in DM header
* BLE: fix data race in broadcast path
- Snapshot peripherals via Array(values) and filter outside sync
- Snapshot subscribedCentrals and centralToPeerID under collectionsQueue
- Mutate subscribedCentrals under collectionsQueue barriers in didSubscribe/unsubscribe
* LocationChannelsSheet: open fully by default (large detent only)
* BLE: remove unused centralMapSnapshot variable
* Geohash DMs: only notify on incoming PM when app is backgrounded; avoid foreground noise
* GeoDM: reliable delivered/read receipts, background-only notifications, and UI tweak
- Implement delivered + read receipts for geohash DMs; send READ on open\n- Handle relay OK acks for gift-wrap sends; resubscribe processes PM/DELIVERED/READ\n- Prevent mesh Noise handshakes for virtual geohash peers (nostr_*)\n- Notify GeoDMs only in background; suppress alerts for already-read msgs\n- Logging: promote key GeoDM receive logs; demote/remove verbose noise\n- UI: remove trailing envelope button from geohash People list
* Fix: remove duplicate variable declarations in AnnouncementPacket.decode()

* Require signed announces; add Ed25519 key/signature/timestamp TLVs and verify
- Protocol: AnnouncementPacket now requires ed25519PublicKey (0x03), announceSignature (0x04), and announceTimestamp (0x05). Encoder emits, decoder requires; unknown TLVs still tolerated.
- NoiseEncryptionService: add canonical announce sign/verify helpers using context 'bitchat-announce-v1'.
- BLEService: sign Announce, include TLVs; on receive verify (±5 min skew) and ignore unverified; store ed25519 key and isVerifiedNickname in PeerInfo.
- Preserve 8-byte on-wire IDs to keep BLE headers small; no per-message bloat.
* Fix Data.append usage for timestamp bytes in Packets and NoiseEncryptionService (use append(contentsOf:) on UnsafeRawBufferPointer)
* BLEService: fix non-optional announce fields and unwrap signature result; enforce required verification path
* Enforce verified-only public messages; append peerID suffix on nickname collisions in handleMessage
* Suffix duplicate nicknames with peerID prefix in snapshots and getPeerNicknames; ensures lists and messages disambiguate 'jack' vs 'jack'
* Include self nickname in collision detection: suffix remote 'jack' when it matches our nickname in lists and public chat
* UI labels: remove space before '#abcd' suffix in names (public chat, peer lists, snapshots)
* Style '#abcd' suffix light gray:
- Public chat: color suffix in sender via AttributedString segments
- People list: split name and color suffix segment; add helper splitNameSuffix()
* Debounce 'bitchatters nearby' notification: add 60s grace before reset when mesh goes empty; cancel reset when peers return
* Lighten '#abcd' suffix: use Color.secondary.opacity(0.6) in public chat sender and People list
* Toolbar peers indicator: use blue when Bluetooth peers present (was default text color)
* Toolbar peers indicator: use grey when zero peers (was red)
* Toolbar peers indicator: use system grey (Color.secondary) when zero peers, not green
* Fix crash: mutate peripherals dict on BLE queue (not main). Move scan restart to BLE queue as well.
* Reduce connect timeout churn: back off peripherals that time out (15s), increase timeout to 8s, skip non-connectable adverts, and demote timeout log to debug; clean backoff map periodically
* Mentions: support '@name#abcd' disambiguation; filter hashtag/URL styling inside mentions; deliver notifications only to the specified suffixed target when collisions exist
* Fix string interpolation in mention log (escape sequence)
* Mentions: parse '@name#abcd' in sender/receiver; render mention suffix grey (not orange/blue/underlined); ensure receiver notifications trigger for suffixed tokens
* Mentions: include own suffixed token 'name#<myIDprefix>' in valid tokens so '@name#abcd' to self is recognized and notified
* Public actions: show own system message by processing own public messages (remove early-return). Private /hug: add local system message for sender's chat.
* Grammar: change local '/hug' message to past tense ('you hugged/slapped'). Notifications: only fire 'bitchatters nearby' on rising-edge; remove 5-min re-fire and increase empty reset grace to 10m.
* Public /hug echo: add local system message so sender sees action immediately (no reliance on echo)
* Fix visibility: expose addPublicSystemMessage on ChatViewModel and use it from CommandProcessor
* use noise pubkey wip
* ttl=0 for signatures
* verification works
