593fd7d737 Harden public intake bounds against untrusted growth (#1451)
* Bound public rate-limit buckets against attacker-keyed growth.

Keep the NIP-13 PoW sender bypass, skip content-bucket minting on
sender reject, and evict idle/oldest entries at a hard cap.

Co-authored-by: Cursor <cursoragent@cursor.com>

* Stop Cashu-looking text from skipping long-message guards.

Oversized public content always collapses and takes the plain
formatting path so remote tokens cannot force layout/regex DoS.

Co-authored-by: Cursor <cursoragent@cursor.com>

* Cap teleported geohash participant markers.

Bound the set with FIFO eviction, clear it on channel switch, and
prune markers that leave the visible participant list.

Co-authored-by: Cursor <cursoragent@cursor.com>

* Bound untrusted Nostr relay frames and event tags.

Reject oversized inbound messages before JSON parse, cap tag
arrays/values at decode, and stop logging raw tag contents.

Co-authored-by: Cursor <cursoragent@cursor.com>

* Fail soft when Noise handshake state is unexpectedly missing.

Replace the initiator startHandshake force unwrap with a guard
that throws invalidState instead of crashing.

Co-authored-by: Cursor <cursoragent@cursor.com>

* Cap geohash nickname cache from remote Nostr events.

FIFO-evict at capacity, clear on channel switch, and prune
nicknames that leave the visible participant list.

Co-authored-by: Cursor <cursoragent@cursor.com>

* Avoid overlapping exclusive access in the rate limiter.

Make bucket helpers static so inout dictionary updates do not
conflict with a mutating call on self.

Co-authored-by: Cursor <cursoragent@cursor.com>

* Fix rate-limiter tests for mutating allow under #expect.

Call allow outside the macro so Swift Testing does not capture an
immutable copy of the struct.

Co-authored-by: Cursor <cursoragent@cursor.com>

* Drop unused WebSocket data helper; reset rate limiter on panic wipe.

dataWithinInboundLimit replaced the unbounded path, and panic clear
should not leave public intake buckets behind.

84d315e62d Bridge dedup: content-derived stable mesh message ID (#1419)
* Bridge dedup keys on a content-derived stable mesh message ID

Public mesh messages carry no message ID on the BLE wire, so every
non-origin device minted a fresh UUID and the bridge's m-tag dedup only
matched on the origin device: duplicate bridged rows, misattributed
"across the bridge" counts, redundant downlink rebroadcasts, and an
m-tag spoof vector (an attacker could claim a victim's message ID).

Every device now derives the same stable ID from the signed wire fields
(sender ID + ms timestamp + trimmed content, SHA256/32 hex) via the new
MeshMessageIdentity — zero BLE wire change. The bridge event's m tag
carries the origin coordinates ["m", senderIDHex, timestampMs] and
receivers recompute the key from those plus the event's own content
instead of trusting a claimed ID; old-format/absent tags fall back to
the event ID as before.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* Fix mixed-version message loss: m tag leads with the derived stable ID

The previous layout (["m", senderIDHex, timestampMs]) broke v1.7.0
receivers: their parser takes m[1] unconditionally as the timeline
dedup key whenever the tag has >= 2 elements, so every bridged message
from a new-version sender keyed on the CONSTANT sender hex and
inject-dedup dropped all but the first. The tag is now
["m", <derived stable ID>, senderIDHex, timestampMs]: old parsers get a
per-message-unique m[1] (exactly today's semantics), while the new
parser recomputes the ID from elements 2-3 plus the event's own content
and never trusts element 1, keeping the recompute-don't-trust property.

Also:
- Soften the overstated security claim in MeshMessageIdentity and the
  BridgeService classify comment: forging a chosen ID onto different
  content is infeasible, but all three hash inputs are cleartext on the
  radio, so identical-content front-running by a radio-local attacker
  remains possible (no worse than the unbridged mesh).
- Fix the stale archivedEchoKeys rationale: re-synced copies of others'
  messages now carry the derived stable ID (insert-by-ID catches them);
  the content key remains for echo--prefixed archive rows + self echoes.
- Tests: old-parser semantics on the new tag (m[1] per-message-unique
  and equal to the derived ID) and a forged-m[1] event that cannot
  pre-poison a genuine message's dedup slot.

dd6b624cae Quality pass on the 1.7.0 batch: fix confirmed bugs, bump to 1.7.1 (#1418)
* Quality pass on the 1.7.0 batch: fix confirmed bugs, bump to 1.7.1

Post-merge review of PRs #1400–#1417 (push-to-talk, mesh bridging, DM
store-and-forward, empty-mesh liveliness, geo-notes). Fixes the confirmed,
well-scoped findings; deeper architectural/security items are tracked
separately.

- PTT hot-mic leak: releasing the mic during VoiceCaptureSession.start()'s
  150ms retry pause left the mic live and streaming for up to 120s, because
  cancel() no-op'd once `completed` was set. Bail after the sleep if the hold
  was released, and make cancel() always tear down a late-started capture.
- Bridge courier depositDrop reported success and burned the dedup slot before
  the drop was actually published (evicted/compose-fail = lying 📦 "carried"
  with no retry). Only consume publishedDropKeys on durable accept; add
  BoundedIDSet.remove() to release evicted/failed slots (uses the dead dedupKey).
- Blocked senders resurfaced via archived "heard here earlier" echoes, the one
  path that bypassed the live block filter — filter at seed time.
- A late optimistic .sent clobbered the router's .carried state; extend
  ConversationStore.shouldSkipStatusUpdate to a full precedence guard
  (sending < sent < carried < delivered < read).
- Read receipts were permanently burned when the router dropped them (marked
  sent then dropped). sendReadReceipt/routeReadReceipt now return Bool; only
  record as sent on a successful route, else retry on the next read scan.
- MessageRouter.cleanupExpiredMessages() had no production caller, so DMs to a
  peer that never reconnects sat on .sending until relaunch — run it in the
  120s bridge sweep.
- Sightings tally now rolls over at midnight while idle; wave notification
  action localized across all 29 locales; bridged anon#tag uses suffix(4) like
  everything else; makeThrowawayIdentity delegates to NostrIdentity.generate();
  .swiftlint.yml excludes .claude worktrees.
- Add regression tests: carried→sent no-downgrade, carried→delivered upgrade,
  evicted pending drop stays retryable.
- Bump MARKETING_VERSION to 1.7.1.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* Fix CI: adjust delivery-status benchmark and drop now-dead addSystemMessage

The stricter no-downgrade guard (delivered/carried never regress to sent) broke
two things the earlier commit didn't catch locally (perf tests are skipped in
the default run, and Periphery runs only in CI):

- PerformanceBaselineTests delivery benchmarks alternated sent <-> delivered
  assuming both directions apply; the delivered -> sent half is now correctly
  skipped, so the pass measured 0 updates. Alternate two delivered timestamps
  instead — every update is real, no downgrade.
- Routing the geoDM "not in a location channel" error into the thread removed
  the only caller of ChatPrivateConversationContext.addSystemMessage, leaving
  it (and its mock) dead per Periphery. Drop the protocol requirement, the mock
  impl, and the now-vacuous systemMessages.isEmpty assertions (the invariant is
  compile-time enforced: the context can no longer emit a public system line).

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* Address review findings: read-receipt dedup, carried-vs-sending, block-time echo purge

- Read receipts: claim the receipt in sentReadReceipts synchronously
  before spawning the routing task (chat open runs two read scans in one
  MainActor stretch, so the async insert let every unread message route
  twice), and release the claim when the route fails so the
  retry-on-failed-route behavior is preserved.

- Delivery status: extend the no-downgrade guard so the `.sending`
  stamp a pre-handshake resend emits can no longer clobber
  carried/delivered/read (the 📦 indicator survived `.sent` but not
  `.sending`).

- Archived echoes: blocking a peer now purges their carried public
  messages from the gossip archive at block time (UnifiedPeerService
  and /block), while the fingerprint-to-peerID mapping is still known —
  the seed-time filter can't resolve offline non-favorite strangers and
  stays only as defense-in-depth. New Transport hook (default no-op) +
  GossipSyncManager.removePublicMessages with immediate persist.

- Bridge courier: an envelope that can't encode within the drop size
  caps fails identically on every attempt; consume the dedup slot so
  the 120s retry sweep stops re-running Noise sealing on it.

- MeshSightingsTracker: cache the day-key DateFormatter instead of
  building one per call.

Tests: double-markAsRead dedup + failed-route retry, carried→sending
no-downgrade matrix, block-time purge (manager + service wiring),
oversize-drop slot consumption.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Also skip the sent→sending downgrade in the delivery-status guard

Codex review follow-up: sendPrivateMessage without an established Noise
session emits `.sending` asynchronously, so it can land after the
message already reached `.sent` and visibly walk "Sent" back to
"Sending...". Treat `.sending` as weaker than `.sent` too — the status
was already truthful. `.failed` → `.sending` stays allowed so a retry
after a real failure remains visible.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Retain Codable properties in Periphery scan (same fix as #1421)

The noiseKey assign-only false positive fired persistently on this branch
(twice, including a rerun) despite the baselined USR. Byte-identical to the
fix on fix/announce-replay-link-steal so the branches merge cleanly in
either order.

020de96519 Mesh bridging: stitch nearby mesh islands over the internet, courier drops, unified settings (#1412)
* Mesh bridging: stitch nearby mesh islands over Nostr, courier drops, settings surface

Three features plus a UI consolidation, all opt-in behind a new Bridge toggle:

Channel bridge: while bridging, outgoing public mesh messages are also
signed (with a derived, unlinkable per-cell Nostr identity) as kind-20000
events tagged #r with the local geohash-6 cell and published to the cell's
deterministic geo relays; mesh-only peers deposit via new toBridge/fromBridge
carrier directions through a bridge gateway (bridge + gateway toggles).
Remote islands' events render into the mesh timeline marked with a network
glyph. Events carry the original mesh message ID so the store's insert-by-ID
absorbs radio/bridge duplicates in either order. Loop prevention mirrors
GatewayService (three BoundedIDSet caches + skip-if-seen-locally + budgets).
Nothing crosses a bridge unless its author signed it for the bridge; a
per-message "nearby only" composer toggle keeps a message radio-only.

Courier over the bridge: sealed courier envelopes park on default relays as
kind-1401 drops tagged #x with their day-rotating recipient tag (NIP-40
expiry), signed by per-drop throwaway keys. Recipients subscribe for their
own candidate tags; bridge gateways watch verified local peers' tags and
hand matching drops over as directed courier packets. DM delivery to known
peers stops requiring a physical courier encounter; the Noise-X seal never
opens in transit.

Presence: kind-20001 heartbeats on the rendezvous feed a "people across the
bridge" count in the header (approximate: local participants subtracted by
radio-copy attribution).

Settings/Info: AppInfoView is now a segmented Settings/Info sheet. Settings
hosts appearance, voice (fixes the duplicated Voice section), a Connectivity
section (bridge + gateway + Tor toggles, the latter two moved out of the
location sheet), and a confirmed panic-wipe button. New announce TLV 0x06
advertises the gateway's rendezvous cell; PeerCapabilities gains .bridge.

i18n: 23 new keys across all 29 locales; coverage tests green.
Tests: 50 new app tests + 3 BitFoundation tests; full suite 1445 green.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Settings polish: one toggle style, sticky Info-first tab, location access in Settings

- The live-voice toggle now uses the same settings card + IRC pill as the
  connectivity toggles (settingToggle, renamed from connectivityToggle).
- Segmented control orders Info first; the selected pane persists across
  opens (AppStorage), so first-ever open lands on Info and afterwards the
  sheet reopens where it was left.
- "remove location access" moved from the channels sheet into the Settings
  Connectivity section (same key, still deep-links to system settings).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Location UX + copy: state-aware access control, honest empty state, clearer bridge/gateway text

- Settings' location control now covers all three permission states: grant
  (real prompt, only possible while never-asked), open-system-settings when
  denied, remove-access when granted. The channels sheet keeps its own grant
  path for people who start there.
- The channels list no longer spins forever without permission; it shows
  "grant location access to find nearby channels" instead (new key, 29
  locales).
- Bridge and gateway subtitles rewritten for clarity; the gateway subtitle
  moved to a new key since it now carries bridge traffic, and the old
  geohash-only key is deleted. The word "user" is banned from copy in every
  locale ("this person is blocked").

* Field-test fixes: dedupe relay-connectivity triggers, throttle presence, log bridge decisions

First on-device run confirmed publishes accepted and the subscription
delivering, but exposed trigger spam: NostrRelayManager's isConnected
re-emits per relay recompute, so presence published 5x/second and the
courier-drop subscription rebuilt 6x in 300ms. removeDuplicates() on the
sinks + a 30s presence throttle (same-second heartbeats are byte-identical
events anyway). Also: injection/skip/downlink now log under 🌉 so field
verification is observable — the first test looked silent precisely because
dedup correctly suppressed same-island bridged copies.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Fix restart self-echo: recognize own rendezvous events by derived pubkey

Second field run proved bidirectional bridging live (~1-2s Mac<->iPhone via
Tor) but caught a bug: relay backfill after an app relaunch re-delivered the
device's own pre-restart events, and with the in-memory published-ID cache
wiped they rendered as bridged copies of your own messages. The rendezvous
identity is deterministically derived per cell, so self-recognition by
pubkey needs no cache and survives restarts; own events are also marked
never-downlink. Regression test simulates the fresh-launch state.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* People sheet: mesh, bridge, and groups in one list

The header's bridged count had no matching faces anywhere — the people
sheet only knew mesh peers. BridgeService now publishes named participants
(nickname from message tags, geohash-style #last4 disambiguation, presence
keeps a known name alive) and the mesh people sheet gains an
"across the bridge" section between mesh peers and groups. Display-only
rows in v1 (bridged identities have no DM route yet). Two new catalog keys
x29 locales; also normalizes one out-of-sort-order entry inherited from a
hand-edited key on main.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Header: one people icon, one count, one sheet

Fold the bridged-people count into the main person.2.fill count instead of
a second network-glyph counter; the merged people sheet (mesh / across the
bridge / groups) is the breakdown. VoiceOver still announces how many of
the total are across the bridge.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* People sheet symmetry: #mesh section header, no active count

Every section now gets the same glyph+label header shape (shared
PeopleSectionHeader): #mesh over the peer list, across-the-bridge over
bridged people. The "N active" line is gone (mesh); location channels keep
their geohash subtitle. Dead subtitle/count helpers removed.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* One switch: the bridge toggle drives all internet sharing

Field feedback: two toggles (bridge + gateway) with an invisible dependency
was a trap — bridged messages silently never reached mesh-only neighbors
unless a second lever was found and flipped. Collapsed to a single switch
that does the right thing for your situation:

- Bridge ON + internet: your messages cross, you see the bridge, AND your
  device serves its island — accepts toBridge deposits, carries remote
  messages onto the radio, watches courier drops for verified local peers,
  advertises the cell, and runs the geohash-channel gateway.
- Bridge ON, no internet: you ride whoever nearby is serving.
- Bridge OFF: nothing of yours crosses; radio reception of bridged traffic
  stays passive and free.

With every online bridger serving, downlink gets a 0.2-1.5s jittered
holdoff + send-time suppression recheck so co-located gateways don't burn
duplicate airtime (two-gateway test included). The internet-gateway card is
gone from Settings (GatewayService now follows the bridge switch, with
launch-time migration); its orphaned catalog keys deleted and the bridge
subtitle broadened across all 29 locales. Also: MeshPeerList's empty state
("nobody around...") aligned to the section row rhythm.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Bridge pumps its own location; fix centered people sheet; stop drop-subscription churn

Field session 3 found the bridge silently cell-less: it read
availableChannels passively, which only flow while some other feature
(channels sheet, location notes, geo sampling) happens to pump location —
turn those off and the bridge never gets a rendezvous. BridgeService now
requests a one-shot fix whenever it's enabled without a cell (and
piggybacks one on the presence timer so moving devices migrate cells).

Also from the session: the people sheet's scroll content hugged its widest
child and got centered on iPhone when the list was empty — pinned to full
width, leading. And the courier-drop subscription rebuilt every ~60s on
verified announces despite an unchanged tag set — now resubscribes only
when the tags actually change.

(Also merges origin/main: keychain test isolation #1413.)

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Fix launch race: bridge reacts to the permission callback, retries cell-less

Field session 4: the launch-time location request ran before the CoreLocation
authorization callback delivered, so refreshChannels() silently no-opped
(it requires .authorized) and nothing ever retried — the bridge stayed
cell-less all session. Three layers now close it:

- a $permissionState sink re-enters refreshRendezvous the moment
  authorization resolves (the fast path),
- the maintenance timer arms even without a cell and retries the full
  rendezvous refresh (the backstop; it previously required a cell, which
  made it useless for exactly this failure),
- flipping the bridge switch while never-asked triggers the location
  prompt — that's the user-initiated moment for it.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* People sheet: one header style for every section; bridged people visible while own bridge is off

GroupChatList's header now uses the shared PeopleSectionHeader (glyph +
label, same size/padding as #mesh and across-the-bridge; keeps its key and
header trait). Bridge section and the header count are no longer gated on
this device's own toggle: bridged people arrive over passive radio from a
serving neighbor, and whoever is visible in the timeline belongs in the
sheet and the count.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* People sheet: equalize the first section's gap

MeshPeerList's first row kept a legacy 10pt top bump from when nothing sat
above it, and the outer VStack's 6pt inter-child spacing applied between
the #mesh header and the list but not inside the other sections. Both gone:
sections own their rhythm (header 12/4, rows 4), spacing 0 outside.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* People sheet: rows drop their leading glyphs — the section header carries the type

Mesh rows lose the per-state transport icon (connected/relayed/nostr/
offline), bridge rows the network glyph, group rows the person.3 icon.
Trailing state badges (star, lock, verified, unread, blocked, crown) stay,
and the row accessibility description still announces connection state, so
VoiceOver loses nothing.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Remove dead code left behind by the Settings|Info consolidation

Periphery (--strict) flagged five leftovers on this branch:
- LocationChannelsModel.setGatewayEnabled: the standalone internet-gateway
  toggle is gone (the bridge switch drives internet sharing), so nothing
  calls it; the gatewayEnabled published property stays for the header dot.
- AppInfoView Strings.Location title/enable/openSettings: the old Location
  section's header and permission buttons no longer exist. Their orphaned
  Localizable.xcstrings entries go with them (the gateway-toggle keys were
  already pruned).
- BridgePeopleList's appTheme environment value was never read.

The sixth CI finding (PrekeyBundleStore.StoredBundle.noiseKey assign-only)
is a Periphery flake: the property is read in loadFromDisk, the finding
didn't reproduce locally or on the next CI run of unchanged code.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* People sheet: mesh rows get their transport glyph back

The mesh section is the one heterogeneous list — the leading icon encodes
HOW a peer is reachable (radio / relayed / nostr-only / offline), which the
header can't say. Bridge and group rows stay glyph-free.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Fix courier drop skipped by stale BLE reachability; periodic deposit sweep

Field test: a DM sent seconds after the recipient's radio vanished still
saw them as "reachable" (60s verified retention), so canDeliverPromptly
held, every deposit was skipped, and the message sat spooled with no retry
path. MessageRouter now sweeps its outbox every 2 minutes and publishes
bridge drops for messages whose recipient no transport can promptly reach;
the drop layer's message-ID dedup makes the sweep idempotent. Regression
test reproduces the exact field sequence.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Show "carried" when a message ships as a bridge drop

Field feedback: dropped DMs delivered but the sender saw nothing — the
drop path never fired onMessageCarried, and the recipient's delivery ack
has no radio route back until the peers next share a transport. depositDrop
now reports whether a fresh drop was sealed and the router marks the
message carried (📦) on both the send path and the sweep; the ack still
upgrades it to delivered whenever a route exists.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Fix locale word order: offline tag after name in DM header; localized "ago"

The private-chat header rendered the localized offline word in the
availability-glyph slot, before the name — "sin conexión bob". Offline now
shows the same dimmed person glyph the mesh list uses, with the word as a
small trailing tag after the name and lock, so it reads correctly in every
locale. Full sweep of views found one more composition bug: notice
timestamps glued English "ago" onto a localized duration; now the whole
phrase comes from RelativeDateTimeFormatter (same as the "fades" label).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* DM header offline state: icon only

The availability slot now reads uniformly as a glyph (radio / relayed /
globe / dimmed person), matching the mesh list; the text tag is gone.
VoiceOver still announces "offline" via the glyph's accessibility label.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Offline glyph: slashed antenna instead of dimmed person

Offline is now the visual negation of connected (same antenna glyph,
slashed) in both the DM header and mesh list rows; a generic person icon
didn't say "unreachable".

d499c3e415 Isolate tests from the developer's real login keychain (#1413)
* Isolate tests from the developer's real login keychain

Every test run prompted for the login keychain password (repeatedly,
since the xctest runner's code signature changes each build, so
"Always Allow" can never stick) and silently deleted the developer's
real Nostr identity via panic-mode tests.

Two holes let tests reach the real keychain:

- NostrIdentityBridge() defaulted to the real KeychainManager. Tests
  inject mocks, but app-side constructions with no injection point
  (LocationNotesManager's static bridge, GeohashPresenceService,
  BoardManager, AppRuntime) read the real chat.bitchat.nostr item
  when exercised under test.
- clearAllAssociations() used raw SecItem* calls that bypassed the
  injected keychain entirely, so panicClearAllData tests wiped the
  real Nostr identity items on every run.

Fix: centralize FavoritesPersistenceService's test-guarded in-memory
default as KeychainManager.makeDefault() and use it for all default
keychain parameters, and add deleteAll(service:) to
KeychainManagerProtocol so clearAllAssociations() goes through the
injected keychain like every other operation.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Share one in-memory test keychain per process (Codex P2)

A fresh store per makeDefault() call diverges from production, where
separate default-constructed bridges share chat.bitchat.nostr —
BoardManager's publish and NIP-09 delete paths would derive different
geohash identities under test. PreviewKeychainManager gains a lock
since the shared instance is reached from arbitrary threads.

4baeaab717 Geo notes latency: EOSE scoped to reached relays + connecting state with auto-retry (#1411)
* Empty-mesh liveliness: nearby conversations, echoes, wave action, dead drops, radar

The empty mesh timeline was a dead end: a grey zero and "nobody in range
yet". This turns it into a live surface and gives the app pull when the
mesh wakes up:

- Nearest conversation: background geohash sampling now tracks actual
  chat messages (not just presence) per regional channel; the empty state
  surfaces the busiest nearby conversation with a preview, one tap to
  join (GeohashChatActivityTracker, fed from GeoPresenceTracker).
- Echoes: the carried 6h store-and-forward window renders as dimmed
  "heard here earlier" rows at launch (new Transport
  collectArchivedPublicMessages -> GossipSyncManager snapshot, decoded
  with signature-derived nicknames; content-identity dedup guards
  against re-synced duplicates).
- Wave: the "bitchatters nearby" notification gains a "wave" quick
  action that broadcasts a mesh 👋 straight from the notification, even
  backgrounded (first UNNotificationCategory in the app).
- Dead drops: /drop pins a note to the current building geohash as a
  kind-1 location note with a 24h NIP-40 expiry; expired notes are now
  dropped client-side at ingest; the notices sheet shows "fades in Xh";
  a "location notes" toggle plus location-permission controls live in
  app info (also fixes the duplicated Voice section).
- Radar: an ambient sonar animation shows the radio scanning, with a
  privacy-safe daily tally ("N devices passed within range today" via
  salted per-day hashes) and a "notes left here" hint that opens the
  notices geo tab.

All new user-facing strings ship in all 29 locales. 1403 tests green,
including new suites for the activity tracker, sightings tally, and
note expiry/drop publishing.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Review round: app-info polish, urgent/expiry parity, centered radar, pin fill, Codex P2s

- App info: LOCATION header uppercased like sibling sections; location
  notes and live voice descriptions shortened (29 locales); redundant
  "location access granted" line removed.
- Notices parity: urgent + expiry controls now show on the geo tab too;
  the bridged Nostr note carries ["t","urgent"] and NIP-40 so relay-side
  readers see both; urgent parsed back from incoming notes.
- Radar moved from the top of the empty state to the center of the chat
  area, below the help text (empty state fills the visible height).
- Header pin fills whenever the scope has notices (was: only unseen),

* Hide macOS segmented picker's built-in label in notices composer (duplicate 'expires in')

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Geo notes: permanent (∞) expiry default, urgent stays mesh-only

- Geo expiry picker gains ∞ as the default: a permanent note posts as a
  pure relay note (no NIP-40 tag, no mesh-board copy — a board copy must
  fade within days, contradicting the ∞ the user picked). 1/3/7d keep
  the board + bridged-note path with NIP-40.
- The notes manager is now owned by the notices sheet (not the list) so
  the composer local-echoes ∞ notes into the list; it revives via
  refresh() after a tab-switch cancel, and its expiry-prune timer
  survives cancel (weak self, dies with the instance).
- Urgent toggle returns to mesh-only per review — notes are ambient;
  the read-side urgent-tag parse stays so tagged notes still render.
- macOS: hide the segmented picker's built-in label (duplicate
  "expires in").

* Geo notes latency: EOSE scoped to reached relays, connecting state with auto-retry

Field finding: opening notices on a cold launch showed "no notices yet"
after ~10s, with notes popping in later — the empty state was a lie told
by two mechanisms:

- EOSE tracking waited on ALL target relays, including ones still
  mid-Tor-circuit; one dead relay of five pinned "loading" until the
  10s fallback. Trackers now count a relay only once the REQ actually
  reached it (marked from the send completion, or proven by its EOSE),
  so the first responding relay resolves the initial load and dropped
  targets can't stall it. The 10s fallback stays as backstop.
- When that fallback fired with ZERO connected target relays (Tor still
  bootstrapping), LocationNotesManager reported .ready with no notes.
  It now enters a .connecting state — rendered as "connecting to
  relays…" instead of the empty state — and polls every 3s, re-
  subscribing for a fresh initial fetch the moment a target relay
  comes up.

New NostrRelayManager.isAnyRelayConnected(among:) feeds the check via
an injectable dependency (tests default to legacy behavior). String
localized in all 29 locales. 1412 tests green, iOS+macOS builds clean.

* Clearing the mesh timeline dismisses echoes for good; tighter divider copy

Triple-tap /clear emptied the timeline but the next launch re-seeded
"heard here earlier" from the persisted archive. A MeshEchoSettings
watermark now records the clear; only messages heard after it come back
(the archive itself still carries everything for peers' sync). The
echo dedup keys reset with it, and panic wipe drops the watermark.

Divider copy tightened to "heard here earlier · last 6h" (29 locales).

* Mark EOSE relays at send initiation, closing the in-flight-send race

Codex P2 on #1411: with several sockets already connected, a fast
relay's EOSE could complete the tracker while a slower relay's async
send completion hadn't yet moved it out of awaitingSend — the initial
load reported done with that relay's stored events still pending.
Relays are now marked awaiting-EOSE synchronously when the REQ send is
initiated (and when a flush skips an already-subscribed relay), so
every relay that was actually asked is counted before any EOSE can
race. Failed sends resolve via the disconnect settle or the fallback.

* Echoes visual polish: tinted history block, radar-captioned tally, ambient footer

Device-test feedback on the echoes screen:
- Archived echoes now sit on a subtle tinted background (secondary at
  8%) in addition to the dim, so "heard here earlier" reads as one
  distinct block; the divider carries the echo ID prefix to join it.
- "N devices passed within range today" moves out of the narration
  lines to sit centered under the radar as its caption.
- When the timeline holds only echoes/system lines, a compact ambient
  footer (small radar + tally + live hints) renders below the history
  instead of the whole ambient layer vanishing.

* Notes strip persists above the mesh chat; leaner empty-state narration

- The 📍 "notes left here" line was empty-state-only, so starting a
  conversation hid it. It is now a tappable strip pinned above the mesh
  timeline whenever unexpired notes exist at this place (opens the
  notices geo tab); the nearby-notes counter runs for the whole mesh
  timeline, not just the empty state.
- Empty state narration drops "nobody in range yet..." (the radar and
  the sightings caption already say it) and the nearby-conversation
  hint moves below the help line instead of splitting the narration.

74b8a47d02 Empty-mesh liveliness: nearby conversations, echoes, wave, dead drops, radar (#1409)
* Empty-mesh liveliness: nearby conversations, echoes, wave action, dead drops, radar

The empty mesh timeline was a dead end: a grey zero and "nobody in range
yet". This turns it into a live surface and gives the app pull when the
mesh wakes up:

- Nearest conversation: background geohash sampling now tracks actual
  chat messages (not just presence) per regional channel; the empty state
  surfaces the busiest nearby conversation with a preview, one tap to
  join (GeohashChatActivityTracker, fed from GeoPresenceTracker).
- Echoes: the carried 6h store-and-forward window renders as dimmed
  "heard here earlier" rows at launch (new Transport
  collectArchivedPublicMessages -> GossipSyncManager snapshot, decoded
  with signature-derived nicknames; content-identity dedup guards
  against re-synced duplicates).
- Wave: the "bitchatters nearby" notification gains a "wave" quick
  action that broadcasts a mesh 👋 straight from the notification, even
  backgrounded (first UNNotificationCategory in the app).
- Dead drops: /drop pins a note to the current building geohash as a
  kind-1 location note with a 24h NIP-40 expiry; expired notes are now
  dropped client-side at ingest; the notices sheet shows "fades in Xh";
  a "location notes" toggle plus location-permission controls live in
  app info (also fixes the duplicated Voice section).
- Radar: an ambient sonar animation shows the radio scanning, with a
  privacy-safe daily tally ("N devices passed within range today" via
  salted per-day hashes) and a "notes left here" hint that opens the
  notices geo tab.

All new user-facing strings ship in all 29 locales. 1403 tests green,
including new suites for the activity tracker, sightings tally, and
note expiry/drop publishing.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Review round: app-info polish, urgent/expiry parity, centered radar, pin fill, Codex P2s

- App info: LOCATION header uppercased like sibling sections; location
  notes and live voice descriptions shortened (29 locales); redundant
  "location access granted" line removed.
- Notices parity: urgent + expiry controls now show on the geo tab too;
  the bridged Nostr note carries ["t","urgent"] and NIP-40 so relay-side
  readers see both; urgent parsed back from incoming notes.
- Radar moved from the top of the empty state to the center of the chat
  area, below the help text (empty state fills the visible height).
- Header pin fills whenever the scope has notices (was: only unseen),
  and Nostr-only nearby notes now light it too.
- Codex P2 fixes: notification completion deferred until the wave action
  is handled (background suspension dropped the send); NIP-40 notes now
  prune on a timer when they expire while displayed; the location-notes
  kill switch retargets the nearby-notes counter immediately.

ef848857b7 Remove dead code found by full Periphery audit; add scan config + advisory CI (#1410)
Periphery 3.7.4 audit of both schemes (macOS + iOS, intersected so
platform-specific code is never touched), with test targets indexed and
the share extension built. 277 dead declarations removed or demoted:
dead forwarding wrappers (ChatViewModel+Nostr/+PrivateChat), removed-
feature remnants (autocomplete command suggestions, back-swipe tuning,
MediaSendError, GeohashParticipantTracker), unused Tor dormancy
bindings, assign-only properties, unused parameters (renamed to _), and
redundant public accessibility. 13 orphaned localization keys deleted
across all 29 locales (old pre-#1392 location-notes UI, app_info
warnings).

Two real tests were flagged as unused because they never ran: Swift
Testing methods missing @Test (NostrProtocolTests.
testAckRoundTripNIP44V2_Delivered, NotificationStreamAssemblerTests.
testAssemblesCompressedLargeFrame). Re-armed both; they pass.

Deliberately kept, now recorded in .periphery.baseline.json: iOS-only
code invisible to the CI macOS scan, C FFI signatures, keep-alive
NWPathMonitor reference, InboundEventKey.eventID (dedup semantics),
wifiBulk capability bit (reserved for Wi-Fi bulk work, used by
BitFoundation package tests), and the String secureClear cluster
(exercised by package tests).

New: .periphery.yml config and an advisory Dead Code CI job (mirrors
the SwiftLint precedent from #1361) that fails on findings not in the
committed baseline.

Verified: full macOS app suite, BitFoundation (119) and BitLogger (13)
package tests green; periphery scan --strict exits clean.

8415c52913 Unified notices: one pin, one sheet for board pins + location notes (#1392)
* Unified notices: merge board pins and location notes into one sheet

One pin icon in the header now opens a single Notices sheet with a
geo/mesh scope toggle, replacing the separate board, location-notes,
and mesh-only note buttons:

- geo tab: current geohash's notices — mesh-synced board posts merged
  and deduped with Nostr kind-1 location notes, with per-item mesh/net
  source badges. Scope follows the selected location channel, or the
  device's building geohash when chatting on mesh.
- mesh tab: mesh-local board only (fully offline).
- One composer: geo posts go to the board and bridge to Nostr (existing
  bridge), so mesh and internet see the same notice.
- Merged delete: tombstoning an own board post now also retracts the
  bridged Nostr copy via NIP-09 (new createDeleteEvent, bridged event
  ids tracked in BoardManager); own Nostr-only notes are deletable too.
- LocationNotesManager accepts any channel-precision geohash (1-12
  chars), not just building-level.

BoardView and LocationNotesView are superseded by NoticesView.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Notices round 2: honest composer, friendlier copy, new-pin chat alerts

- Urgent + expiry controls now appear on the mesh tab only: the bridged
  Nostr copy of a geo post carries neither, so relay-side readers would
  never see them. Geo posts default to non-urgent with 7-day expiry, and
  the bridged note now gets a NIP-40 expiration tag so honoring relays
  drop it in step with the board copy.
- Geo tab explainer reuses the original location-notes description
  (keeps its 29 existing translations); mesh tab gets a new plain-
  language description.
- New-pin chat alerts, fully local (no wire traffic): BoardStore fires
  postArrivals for posts newly accepted from the wire; BoardAlertsModel
  filters own posts, dedups by postID, and for urgent pins created
  within the last 30 minutes emits one system line into the matching
  timeline (geo pin -> that geohash's chat, mesh pin -> mesh chat),
  collapsing simultaneous arrivals into a count line.
- Routine pins light up the header: the pin icon tints orange whenever
  the current scope has notices at all, and fills (pin.fill) while
  unseen new pins are waiting; opening the sheet clears them.

* i18n: translate the unified-notices strings into all 28 non-English locales

Adds the 13 new notices keys (sheet title, geo/mesh tabs, mesh
description, source badges, urgent alert lines, button tooltip and
accessibility strings) to the string catalog with translations for
every locale the app ships. The geo tab already reuses the fully
translated location_notes.description; this covers the rest. Insertion
preserves the catalog's case-insensitive key order, so the diff is
purely additive.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Address Codex review: panic-wipe reset, scoped badge clear, geohash-aware dedupe

- BoardStore.wipe() now emits didWipe; BoardAlertsModel subscribes and
  resets, so a panic wipe drops pending urgent lines (which could
  otherwise re-append pre-wipe content into chat after the collapse
  flush), unseen badge scopes, and handled-post history.
- Opening the notices sheet clears unseen badges only for the scopes it
  actually shows (mesh + current geo scope); pins for other geohash
  channels keep their badge until visited.
- LocationNotesManager.Note now retains the matched g tag, and the
  bridged-copy dedupe requires the note's geohash to equal the board
  post's — a same-text note from a neighboring cell is no longer
  swallowed as a duplicate.

ede6368296 NIP-13 proof-of-work for geohash channels: mine on send, relax rate limits for PoW senders (#1382)
* NIP-13 proof-of-work for geohash channels: mine on send, relax rate limits for PoW senders

Outgoing kind-20000 geohash messages mine a NIP-13 nonce tag (8 leading
zero bits, ~256 hashes, typically <1 ms) off the main actor before
signing. Mining is hard-capped at 2 s and cancellable (newer send or
channel switch): on cap/cancel the committed target steps down so the
message still ships promptly with an honest commitment - sending is
never blocked and nothing is dropped. The hot loop serializes the
canonical event once and rewrites only the fixed-width nonce bytes.

Inbound kind-20000 events are scored per NIP-13 commitment semantics
(committed target counts; the ID must actually meet it, extra work
earns nothing) and never hard-rejected: validated PoW >= 8 bits skips
the per-sender rate-limit bucket while the per-content flood bucket
still applies, so old non-mining clients keep working under today's
strict limits while bulk spam gets expensive.

Presence heartbeats (kind 20001), kind-1 notes, and DMs are unchanged;
no UI beyond a pow= field in an existing sampled debug log.

Reimplemented from scratch rather than cherry-picking the stale
feature/pow-geohash-mining-ui branch (unbounded loop, hard receive
filtering, mining UI, XCTest, force unwraps).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Geohash: serialize PoW sends so order matches send order

Two location-channel sends back-to-back only cancelled the previous
mining task and started a new one. Cancellation merely *expedites* NIP-13
mining (the target is polled and steps down; it never aborts the send),
so the cancelled task still appended + relayed once mining returned. Both
tasks ran concurrently and the second (shorter to mine) could finish
first, reordering messages in the timeline and on relays.

Chain the mining tasks: each geohash send captures the previous send's
task, cancels it (to expedite, so delays never stack), and awaits its
completion before it echoes and relays. Order is now always send order.
The >2s mining cap is preserved: cancellation expedites the awaited task,
so a send is never blocked beyond NostrPoW.miningTimeCap.

Test: two rapid sends where the first mines longer (larger content) still
land in send order for both the local echo and the relayed events.

a66c591f8e Courier: deposit in parallel when the only route is a send queue (#1368)
* Deposit with couriers in parallel when the only route is a send queue

The courier path was nearly unreachable: NostrTransport claims any
favorite with a known npub as "reachable" regardless of connectivity,
and the mesh favorite exchange shares npubs, so for essentially every
courier-eligible recipient the router picked Nostr's reachable branch.
With no internet the message just sat in the relay send queue — in the
flagship scenario (internet shutdown, mutual friend standing right
there) the courier walked away carrying nothing.

Add Transport.canDeliverPromptly(to:), defaulting to reachability for
radio-backed transports; NostrTransport answers honestly by mirroring
the relay manager's connection state (fail-closed behind Tor). When the
chosen transport can't hand the message off promptly, the router now
also deposits a sealed copy with connected couriers. Double delivery is
harmless: receivers dedup by message ID, and delivered/read acks never
downgrade the carried status. When relays are up, sends are trusted and
no courier quota is spent.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Track DM-relay connectivity, not any-relay, for prompt delivery

Codex review: NostrRelayManager.isConnected is true when any relay is
up, including geohash/custom relays — but private messages target the
default (gift-wrap-capable) relay set and queue when none of those are
connected. A lone geohash relay would have suppressed the parallel
courier deposit while the DM sat in the queue. Publish a DM-scoped
connectivity flag and drive canDeliverPromptly from it.

b31a63ce37 Burn down SwiftLint advisory violations from 109 to 4 (#1362)
Mechanical style fixes across the enabled rule set, mostly via
swiftlint --fix (trailing_comma, comma, colon, trailing_newline,
comment_spacing, unused_closure_parameter, unneeded_break_in_switch,
opening_brace) plus hand fixes:

- non_optional_string_data_conversion (45): .data(using: .utf8)! and
  ?? Data() fallbacks replaced with the non-optional Data(_.utf8),
  including two production sites (NIP-44 HKDF info constant and the
  announce canonicalization context/nickname bytes — byte-identical
  output, only the impossible-nil handling is gone).
- switch_case_alignment: LocationChannel had a misindented closing
  brace; also repaired an --fix artifact in BLEService's .none case.
- redundant_string_enum_value: TrustLevel raw values equal to the case
  names (encoded form unchanged).
- unused_optional_binding: let _ = binds replaced with != nil / is Bool.
- static_over_final_class: PreviewView.layerClass.
- Resolved the BinaryProtocolTests TODO by documenting that 8-byte
  recipient ID truncation is the fixed wire-field size, not a bug.

The 4 remaining violations are all todo markers for a shared
test-helpers module (tracked in #1088) and one Reuse note.

jackandClaude Fable 5 ca63893197 Fix security audit findings: 3 critical, 7 high
A broad audit surfaced ten critical/high issues across the crypto,
transport, identity, and panic-wipe layers. This fixes all ten.

Critical:
- Nostr DMs were unauthenticated. The NIP-17 seal was signed with a
  throwaway ephemeral key and the receiver never verified it, so anyone
  who knows a recipient's npub could forge messages (and delivery/read
  receipts) into an existing trusted conversation. The seal is now
  signed with the sender's real identity key, and the receiver verifies
  the seal signature and that seal.pubkey == rumor.pubkey.
  NOTE: this is a breaking wire-protocol change (see PR).
- Public BLE messages trusted registry membership instead of the packet
  signature. Since senderID is attacker-controlled, any verified peer
  could be impersonated in public chat. A valid signature from the
  claimed sender is now required before any registry identity is used.
- Unverified announces still persisted the announced identity, letting a
  replayed noisePublicKey overwrite a victim's stored signing key and
  nickname. persistIdentity is now gated on verification.

High:
- Noise decrypt trapped on a 16-19 byte ciphertext (negative prefix
  length after nonce extraction) — a remote crash. Now validated.
- Identity-cache debounce save used Timer.scheduledTimer on a GCD queue
  with no run loop, so it never fired; block/verify/favorite changes
  only persisted on explicit forceSave. Replaced with a
  DispatchSourceTimer on the queue; forceSave is now serialized.
- Identity-cache key load couldn't tell "missing" from a transient
  keychain failure and would regenerate (deleting) the key, orphaning
  the cache. Now uses getIdentityKeyWithResult and falls back to a
  session-only ephemeral key without clobbering the persisted key/cache.
- BLE receive-dedup key lacked a payload digest, so post-handshake
  flushes (queued msgs + delivery/read acks in the same ms) were dropped
  as duplicates. Digest added, matching the ingress registry.
- Maintenance timer was created only in init and never recreated after a
  panic stop/start, silently degrading the mesh until app restart. Now
  recreated in startServices.
- Panic wipe left persisted location state (selected channel, teleport
  set, bookmarks) and cached per-geohash Nostr private keys behind. Both
  are now cleared.
- Panic spawned an orphan NostrRelayManager instead of reusing .shared,
  splitting relay state from every other component. Now reuses .shared.

Tests updated to assert the fixed behavior (announce no longer persists
unverified identities; public messages require a signature; receive
dedup ID includes the payload digest).

jackandClaude Fable 5 0b007eee1a Close the final re-grade findings: parked EOSE fallback, panic atomicity, overflow visibility
EOSE callbacks parked while Tor is bootstrapping now get a fallback
unblock at the standard 10s EOSE timeout (via the injected scheduler,
generation-guarded, single-fire) instead of waiting up to ~225s for
Tor-readiness retry exhaustion. The identity swap in
refreshPeerIdentity runs inside a messageQueue barrier with re-entrancy
guard, so a panic reset can no longer race in-flight packet builds
(deadlock analysis documented; both call paths verified off-queue).
Relay send-queue overflow drops now log a sampled warning.

Router drops log both outcomes (marked failed / skipped by no-downgrade

log their counts; mirrored republishes get a sampled proof line. 11 new
invariant tests corrupt store state through DEBUG-only hooks since the

MessageRouter outbox drops (attempt cap, TTL expiry in flush and
cleanup, per-peer overflow eviction) now invoke onMessageDropped, wired
to mark the message .failed in the ConversationStore - guarded so a
late failure never downgrades an already delivered/read status.

NostrRelayManager pending subscriptions gain a per-relay cap (64,
oldest-by-sequence eviction; durable intent still replays from
subscriptionRequestState) and a 10-minute age sweep on the existing
connect path. Reconnect backoff gets injectable +/-20% jitter so
recovering relays don't thundering-herd.

relays:

- Replay active subscriptions on every relay (re)connect. Relays drop
  REQs with the socket; previously a drop silently killed the
  subscription on that relay for the rest of the session. Durable
  subscription intent now also survives disconnect()/resetAllConnections
  (background -> foreground).
- Keep failed REQ sends queued instead of dropping them.
- Raise the EOSE fallback from a fixed 2s Timer to a 10s injected
  schedule (Tor needs more than 2s), and settle EOSE trackers when a
  relay disconnects before answering so initial load doesn't stall.
- Decay "permanently failed" relay markings after a 10-minute cooldown;
  previously ~9 minutes of outage (or one DNS hiccup) excluded a relay
  until app restart, with nothing resetting it on macOS.
- Make geo relay selection deterministic (distance, then host) so
  publishers and subscribers with the same directory agree on relays.
- Post .geoRelayDirectoryDidRefresh after a directory fetch and let
  LocationNotesManager auto-resubscribe out of the "no relays" state
  instead of requiring a manual retry.

* Guard subscription activation on connection identity

A REQ send completion from a dead socket could land after
handleDisconnection cleared the relay's subscriptions and re-mark the
subscription active, making the next connection skip the durable replay
and leave that relay silent. Only mark a subscription active if the
completing socket is still the relay's live connection.

Regression test defers send completions in the mock so the stale
completion deterministically interleaves between disconnect and
reconnect.

Addresses Codex review on #1333.

jackandClaude Fable 5 4b287f7490 Stop paying for filtered log messages; sample per-event hot-path logs
SecureLogger's public wrappers evaluated their message autoclosure before
the level check inside log(), so every filtered debug message across the
codebase still paid for string interpolation - hundreds of call sites on
the per-packet/per-event hot paths. The wrappers now guard the level
first, and debug() compiles out of release builds entirely. Regression
tests verify filtered messages are never constructed.

The two heaviest per-event debug logs (NostrRelayManager inbound events,
ChatNostrCoordinator geo events) are now sampled every 100th with a
running count, so debug-enabled dev builds stop emitting hundreds of
lines per minute in busy geohashes.

jackandClaude Fable 5 6bda919dd4 Fix transport reliability gaps: Tor stalls, weak-signal sends, GCS input validation
NostrRelayManager no longer strands work when Tor is slow to bootstrap:
failed readiness waits retry (bounded by nostrTorReadyMaxWaitAttempts)
instead of dropping queued relay connections, parked EOSE callbacks fire
after exhaustion so callers never hang, and sends made before Tor is
ready are queued locally (capped) instead of being dropped on a failed
wait - still strictly fail-closed.

MessageRouter now prefers a connected transport over a merely
window-reachable one, and sends made on a weak reachability signal are
retained in the outbox until a delivery/read ack confirms receipt
(receivers dedup by message ID), with resends bounded by attempt count.

GCS sync filters from the wire are bounds-checked (p in 1...32, m > 1)
at both the packet decode and filter decode layers; oversized Golomb
parameters previously decoded to garbage via silent shift overflow.

BLELinkStateStore is now explicitly pinned to bleQueue: debug builds
trap any access from another queue, enforcing the ownership discipline
the surrounding code already relied on by convention.

CI gains an iOS simulator build job (arm64 only; the vendored Arti
xcframework has no x86_64 simulator slice) so iOS-conditional code
paths are compile-checked - SPM tests only cover the macOS slice.

jack dffce9d63f Replace precondition() with throwing errors in XChaCha20Poly1305Compat
precondition() crashes the app in release builds if violated. This is
dangerous for cryptographic code that may receive malformed input from
network data or key derivation bugs.

Changed to guard statements that throw typed errors instead:
- XChaCha20Poly1305Compat.Error.invalidKeyLength
- XChaCha20Poly1305Compat.Error.invalidNonceLength

This allows callers to handle errors gracefully rather than crashing.

Critical fixes:
- BinaryProtocol: Return nil for unknown versions (prevents buffer underflows)
- Add BinaryProtocol.Offsets struct to centralize magic numbers
- Replace magic offset calculations with named constants

Security/Privacy:
- FileAttachmentView: Use url.lastPathComponent instead of url.path
  (prevents exposing full system paths)

Documentation:
- Fix compression algorithm documentation (zlib, not LZ4)

All tests passing.

* Fix UI freeze when receiving voice notes

Problem: AVAudioPlayer initialization in VoiceNotePlaybackController.init()
was running synchronously on main thread during view creation, blocking
UI for 50-200ms per voice note.

Solution:
- Remove eager preparePlayer() call from init
- Load duration asynchronously on background queue
- Player is only prepared when playback is actually requested via ensurePlayerReady()

This prevents UI freezes when voice notes appear in the chat.

* Fix memory leaks and post-playback freeze

Fixes:
1. Post-playback freeze: audioPlayerDidFinishPlaying now dispatches to main
   thread before updating @Published properties (Swift concurrency violation)

2. Unbounded waveform cache: Implement LRU eviction with 20-entry limit
   - Track last access time for each cached waveform
   - Evict oldest entry when cache is full
   - Prevents unlimited memory growth as voice notes accumulate

3. Audio buffer memory leaks: Wrap computeWaveform in autoreleasepool
   - AVAudioPCMBuffer allocations are autoreleased
   - Pool ensures buffers are freed promptly

4. Image processing memory: Add autoreleasepool around compression loops
   - Each jpegData() call creates temporary objects
   - Inner pool per iteration prevents memory spikes during quality search

Memory should now remain stable during extended use.

* Eliminate disk I/O from SwiftUI view rendering path

Critical performance fix for UI freezes when receiving media:

Problem: mediaAttachment(for:) was called during every SwiftUI render,
performing synchronous disk I/O on main thread:
- FileManager.fileExists() called 2-6x per message (checking subdirs)
- applicationFilesDirectory() creating directories on every call
- With multiple media messages, this meant 20-100+ disk ops per render

Solution:
1. Remove fileExists checks - construct URLs directly
   - Files are validated during playback/display (fail gracefully if missing)
   - Sender determines subdirectory (outgoing vs incoming)

2. Cache applicationFilesDirectory() result
   - Static cache prevents repeated FileManager.url() calls
   - Directory created only once

3. Remove redundant playback.replaceURL() in VoiceNoteView.onAppear
   - Controller already initialized with correct URL

This eliminates ALL disk I/O from the view rendering hot path.

* Cache Nostr identity derivation to prevent crypto during view rendering

Critical performance fix:

Problem: formatMessageHeader() called deriveIdentity(forGeohash:) during
every SwiftUI render for every media message. Each call performed:
- Keychain I/O (getOrCreateDeviceSeed)
- HMAC-SHA256 computation
- Up to 10 secp256k1 key validations (elliptic curve crypto)

With multiple media messages, this resulted in 100s of milliseconds of
blocking crypto on main thread per render cycle.

Solution: Add thread-safe cache for derived identities
- Check cache before expensive crypto operations
- NSLock protects concurrent access
- Identity is deterministic per geohash, so caching is safe

This eliminates crypto from the hot rendering path.

* Cache geohash identity in ChatViewModel to prevent crypto during rendering

Additional optimization for location channels (voice notes are mesh-only,
but this helps with text message rendering in geohash channels):

- Add cachedGeohashIdentity to avoid deriveIdentity calls during rendering
- Check cache before falling back to crypto derivation
- Reduces main thread crypto work in location channels

* Make voice note loading completely lazy with deferred initialization

Aggressive performance optimization to prevent UI freezes:

Problem: Even with async loading, creating 10+ VoiceNotePlaybackController
instances simultaneously (when scrolling past multiple voice notes) spawned
20+ concurrent background tasks, potentially starving main thread.

Solution - Ultra-lazy loading:
1. VoiceNotePlaybackController.init() now does ZERO work
   - No duration loading
   - No player creation
   - Instant initialization

2. Duration loaded on-demand via public loadDuration() method
   - Called from VoiceNoteView.onAppear after 150ms delay
   - Reduced priority: .utility instead of .userInitiated
   - Guard prevents duplicate loading

3. Waveform loading also deferred 150ms
   - Gives UI time to settle after message appears
   - Prevents task storms when multiple voice notes appear

This spreads the work over time instead of all at once.

* Ensure /clear and panic triple-tap delete media files

Fix: /clear command and panicClearAllData() now properly delete media files

1. /clear (triple-tap on chat):
   - Deletes outgoing media (voice notes, images, files)
   - Conservative: only our sent media, preserves received media
   - Runs in background to avoid UI freeze

2. panicClearAllData() (triple-tap on bitchat/ header):
   - Deletes ALL media files (incoming + outgoing)
   - Removes entire files directory and recreates structure
   - Ensures complete data wipe for emergency scenarios

Both operations run async on .utility queue to prevent blocking UI.

* Fix infinite render loop and apply all security fixes

CRITICAL BUG FIX - Infinite Render Loop:

Root Cause: Duplicate view identity in ContentView.swift:368
  ForEach(messageItems) { item in  // Already uses item.id via Identifiable
      messageRow(...)
          .id(item.id)  //  REDUNDANT modifier caused identity re-evaluation loop
  }

When @Published properties updated, SwiftUI re-evaluated .id() → appeared as
'new' identity → triggered re-render → infinite loop. Caused UI freezes,
keyboard failures, and 100% CPU usage.

Fix: Remove redundant .id() modifier - ForEach already has stable identity.

PERFORMANCE FIXES:

1. Waveform Cache Deadlock (Waveform.swift)
   - Removed nested queue.async(barrier) on cache hits
   - Was causing task saturation and potential deadlocks

2. Async Send Pattern (ContentView.swift)
   - Clear input immediately, defer actual send to next runloop
   - Prevents blocking current event handler

3. Proper Swift Concurrency (VoiceNoteView.swift)
   - Switch from .onAppear + DispatchQueue to .task
   - Cleaner async/await pattern for loading

4. Remove Redundant objectWillChange (ChatViewModel.swift)
   - @Published already triggers updates automatically
   - Explicit send() was causing double update cycles

SECURITY FIXES (C1-C5, H1-H2):

C1. Path Traversal Protection (BLEService.swift)
    - Unicode normalization, null byte removal
    - Replace ALL path separators, reject dotfiles
    - Validate paths don't escape directory

C2. Integer Overflow (BitchatFilePacket.swift)
    - Use UInt64 for TLV parsing, safe Int conversion

C3. MIME Validation (BLEService.swift)
    - Whitelist: JPEG, PNG, GIF, WebP, M4A, MP3, WAV, OGG, PDF
    - Magic byte validation for all types
    - Lenient on M4A (platform variations)

C4. Compression Bomb (BinaryProtocol.swift)
    - Ratio validation <= 50,000:1
    - Defense-in-depth with 1MB size cap

C5. TOCTOU Race (ChatViewModel.swift)
    - Direct removeItem without fileExists check

H1. File Size Validation (ChatViewModel, ImageUtils)
    - Check attributes BEFORE Data(contentsOf:)
    - Prevents memory exhaustion

H2. Metadata Stripping (ImageUtils.swift)
    - Remove ALL metadata keys from JPEG encoding
    - Only compression quality set
    - Protects GPS/EXIF/device info privacy

RESULT:
 No render loops
 Works with Xcode debugger
 Voice notes display properly
 All security vulnerabilities fixed
 164 tests passing

Production ready.

* Complete all translations to 100% and fix auto-extraction

- Mark non-localizable strings with Text(verbatim:) to prevent extraction
- Update UI strings to lowercase per style guide (open, save, close, recording)
- Add complete translations for all 29 languages (194/194 strings at 100%)
- Remove empty/duplicate entries (@, bitchat/, Open, Recording %@)
- Add proper localization comments for all user-facing strings

* macOS: Focus message input on launch instead of nickname field

* Remove debug print statements from sendMessage

* Optimize voice note codec to 16 kHz / 20 kbps for smaller file sizes

- Reduce sample rate from 44.1 kHz to 16 kHz (telephony standard)
- Lower bitrate from 32 kbps to 20 kbps
- Results in ~37% file size reduction (~150 KB/min vs 240 KB/min)
- Increases max voice note length from 4.4 to 7 minutes over 1 MiB BLE limit
- Maintains excellent voice quality using native AAC-LC codec

* Fix critical security issues in fragment reassembly and file cleanup

Fragment Reassembly Race Condition (CRITICAL):
- Wrap all incomingFragments/fragmentMetadata access in collectionsQueue.sync
- Prevents concurrent modification crashes from multi-threaded access
- Minimizes lock contention by doing heavy work (reassembly/decode) outside locks
- Add upper bound check: reject fragments with total > 10,000 (DoS prevention)
- Add cumulative size validation before storing fragments (memory DoS prevention)

File Cleanup Path Traversal (CRITICAL):
- Use NSString.lastPathComponent to extract filename safely
- Prevents directory traversal attacks via malicious filenames
- Add path prefix validation before file deletion
- Now checks both incoming and outgoing directories (fixes disk leak)

Additional Protections:
- Fragment assemblies now limited by both count (128) and cumulative bytes (1MB)
- Explicit checks for "." and ".." filenames in cleanup
- Defense-in-depth: multiple validation layers

* Fix post-rebase compilation errors

- Remove duplicate NostrIdentityBridge and Bech32 from NostrIdentity.swift (now in separate files)
- Add caching to NostrIdentityBridge.deriveIdentity() for performance
- Remove duplicate NotificationStreamAssembler from BLEService.swift
- Remove duplicate function declarations in BLEService.swift
- Remove duplicate DeliveryStatusView and PaymentChipView from ContentView.swift
- Fix PeerID type conversions throughout (use .id for String, PeerID(str:) for wrapping)
- Update ContentView body to use main's simple VStack structure
- Fix NostrIdentityBridge instance method calls
- Remove privateChatView (replaced with sheet-based UI in main)

Build and tests passing (137/139 tests pass).

* Fix remaining compilation issues after rebase

- Fix PhotosUI import order (must be after platform imports)
- Fix Data.WritingOptions.atomic reference
- Add identity derivation caching to NostrIdentityBridge
- Fix all remaining PeerID type conversions in ChatViewModel
- Fix ContentView body structure to use main's VStack layout
- Fix PaymentChipView API usage (now uses PaymentType enum)

Build and tests now passing.

* Add proper availability checks for PhotosPickerItem

PhotosPickerItem requires iOS 16+ / macOS 13+ but canImport(PhotosUI)
succeeds on older macOS versions. Add compiler version check to ensure
PhotosPicker code only compiles when actually available.

This fixes CI build failures on older macOS environments.

* Limit PhotosPicker to iOS only to fix CI

PhotosPickerItem has SDK availability issues on macOS in CI.
Change PhotosPicker from canImport(PhotosUI) to os(iOS) only.

macOS users can still import images via file importer (.fileImporter).
This is actually cleaner as macOS file picker is more familiar to users.

Fixes CI build failures.

* Convert new tests to Swift Testing

* Fix compilation issue

* Add the missing `fileTransfer` case

* Explicitly list all Enum cases to get compile-time errors

* Revive lost `NotificationStreamAssembler` changes

* Allow file fragments to account for protocol overhead

* Simplify PR: Focus on audio+image, fix EXIF stripping, remove file transfers

- Fix critical EXIF privacy issue in iOS image processing
  - Both iOS and macOS now use CGImageDestination for metadata stripping
  - Shared encodeJPEG function ensures no GPS, camera, or metadata leaks

- Remove file transfer functionality to simplify PR scope
  - Deleted FileAttachmentView
  - Removed sendFileAttachment from ChatViewModel
  - Removed file picker UI from ContentView
  - Simplified attachment dialog to image only (iOS) or voice only

- Keep focused media features:
  - Voice recording and playback
  - Image sending with progressive reveal
  - Binary protocol for media transfer

* Improve camera UX: Direct camera access with camera icon

- Change paperclip icon to camera icon for clearer affordance
- Open camera directly on tap (no confirmation dialog)
- Add CameraPickerView wrapper for UIImagePickerController
- Remove PhotosPicker in favor of direct camera access
- Images still processed through ImageUtils with EXIF stripping
- Accessibility: Added 'Take photo' label

* Full-screen camera with photo library option

- Change to fullScreenCover for immersive camera experience
- Add action sheet with 'Take Photo' and 'Choose from Library' options
- Renamed ImagePickerView to support both camera and library sources
- Both options open full-screen for better UX
- Updated accessibility label to 'Add photo' (more accurate)

* Fix camera white bars with overFullScreen presentation

- Changed modalPresentationStyle from .fullScreen to .overFullScreen
- This should eliminate white bars at top/bottom on notched devices
- Explicitly set showsCameraControls and cameraOverlayView for camera mode

* Gesture-based photo access: Tap for library, long-press for camera

UX improvements:
- Tap camera icon → Photo library (common use case)
- Long press camera icon (0.3s) → Direct camera (quick photos)
- Removed action sheet entirely for cleaner flow
- Power users can long-press for instant camera access

This is more discoverable and eliminates an extra step in the UI.

* Simplify camera presentation to reduce frame errors

- Changed back to standard .fullScreen presentation
- Removed overFullScreen which was causing frame dimension errors
- Let iOS handle safe areas automatically (white bars are intentional)
- Reduces gesture gate timeout warnings

Note: White bars on notched devices are iOS default behavior for
UIImagePickerController. This respects safe areas for status bar
and home indicator. True edge-to-edge would require custom AVFoundation
camera implementation.

* Force dark mode on camera/picker for black safe area bars

- Set overrideUserInterfaceStyle = .dark on UIImagePickerController
- Changes white bars to black (much better looking)
- Camera controls and photo library also appear in dark mode
- Consistent dark appearance regardless of system settings

* Optimize sheet presentation for camera UI

- Force .large detent for maximum height
- Hide drag indicator for cleaner look
- Use ignoresSafeArea to give camera full space
- Should show complete flash button and controls

* Fix P1: Add DoS protections to PeerID fragment handler

Critical security fix addressing Codex review feedback:

The PeerID overload of handleFragment (which is actually called by
CoreBluetooth) was missing key safety checks that existed in the
String overload:

1. Added total <= 10000 check to prevent unbounded fragment counts
2. Added cumulative size check against FileTransferLimits before
   storing each fragment
3. Prevents memory exhaustion DoS attacks via malicious fragment streams

This ensures the actually-used code path has proper bounds checking.

* Fix decompression size limit to support max-sized file transfers

Root cause: BinaryProtocol.decode() was rejecting decompressed payloads
larger than maxPayloadBytes (1 MB), but TLV-encoded file transfers are
slightly larger due to metadata overhead.

Fixes:
- Changed decompression limit from maxPayloadBytes to maxFramedFileBytes
- This accounts for TLV overhead (~50 bytes) + binary protocol headers
- Now allows ~1.12 MB decompressed payloads (1 MB + overhead budget)

The failing test was:
- Creating 1 MB file content
- TLV encoding adds ~50 bytes (1,048,627 total)
- Compression reduces to ~1,084 bytes (highly repetitive data)
- During decode, decompression was rejecting the 1,048,627 byte output
- Now correctly allows it since 1,048,627 < 1,179,760 (maxFramedFileBytes)

All 154 tests now pass including 'Max-sized file transfer survives reassembly'

* Fix critical thread-safety crash in PeerID fragment handler

CRITICAL: The PeerID version of _handleFragment was accessing
incomingFragments dictionary without collectionsQueue synchronization,
causing crashes when multiple BLE threads processed fragments concurrently.

Crash stack trace pointed to line 3431 (dictionary subscript) with:
'doesNotRecognizeSelector' - classic concurrent mutation crash.

Fix:
- Wrapped ALL incomingFragments/fragmentMetadata access in
  collectionsQueue.sync(flags: .barrier)
- Matches the thread-safe pattern used in String version
- Separate cleanup into its own barrier block after reassembly
- Prevents concurrent dictionary mutations from multiple BLE threads

This is the same pattern as the String version (line 1128) which didn't crash.

* Remove Localizable.xcstrings formatting noise

The Localizable.xcstrings file had massive formatting-only changes
(spacing: 'key' vs 'key :') that added 50K+ lines to the PR diff.

This was just Xcode reformatting with no actual string changes.

Reverted to main's version to keep PR focused on actual code changes.

* Add macOS photo picker support

- Added MacImagePickerView with NSOpenPanel for macOS
- macOS shows photo.circle.fill icon (no camera hardware)
- Opens native file picker for images (.png, .jpeg, .heic)
- Images processed through ImageUtils with EXIF stripping
- Simple sheet with Select/Cancel buttons

Cross-platform photo sharing now works:
- iOS: Tap for library, long-press for camera
- macOS: Tap for file picker

* Add Localizable strings for camera and voice features

Xcode auto-generated localization strings for new UI elements:
- Camera/photo picker labels
- Voice recording UI strings
- Media attachment descriptions

These are legitimate new strings needed for the audio+image feature,
not just formatting changes.

- Display '± 1' indicator in LocationNotesView header

Coverage:
- Single cell: ~38m × 19m
- 3×3 grid: ~114m × 57m total area
- Better discovery of nearby activity

Behavior:
- Subscribe: Fetches notes from all 9 cells (single efficient subscription)
- Post: Still uses center geohash only (correct privacy-preserving behavior)
- UI: Shows 'geohash ± 1' to indicate expanded coverage

3a35b3acc2 Modularization: Extract Tor into a separate module (#602)
* Extract Tor into a separate module

* Add Tor package as a dependency for iOS & macOS targets

* Move `tor-nolzma.xcframework` inside Tor

* Remove `libz` from Frameworks as its linked in Tor

* Remove stray `.gitkeep` from macOS target membership

* Fix missing import and access control for modularized Tor

- Add import Tor to NetworkActivationService
- Make TorManager.shutdownCompletely() public for external access

* Fix tor-nolzma.xcframework structure for Xcode builds

- Add missing Info.plist files to all framework slices
- Restructure macOS framework to use deep bundle format (Versions/)
- Keep iOS frameworks as shallow bundles (standard for iOS)

This fixes the Xcode build errors while maintaining SPM compatibility.

* Remove stale xcframework references from Xcode project

Xcode cleaned up old direct references to tor-nolzma.xcframework
since it's now managed internally by the Tor Swift package.
