Bisecting (base was 4/4 clean, branch 3/3 hung, reliably reproducible)
pinned the parallel-suite exit hang to the public-message signature
requirement (security fix#2), via FragmentationTests:
reassemblyFromFragmentsDeliversPublicMessage and
duplicateFragmentDoesNotBreakReassembly send fragments of an UNSIGNED
public message and `await capture.waitForPublicMessages(...)`. With #2 the
reassembled unsigned message is now (correctly) dropped, so
didReceivePublicMessage never fires. The helper then trips a latent bug:
on timeout it cancels the waiter task but never resumes its
CheckedContinuation, so the throwing task group's teardown awaits a child
that never completes and the whole test process hangs at exit (SIGKILL'd
by CI). Base never hit it because the message always arrived in time.
Fix matches the security model — real public broadcasts are signed: sign
the reassembled packet with a NoiseEncryptionService and preseed the
sender's signing key (same pattern as duplicatePacket_isDeduped), so #2
verifies and delivers it. Full parallel suite now exits cleanly 5/5 locally
(branch was 3/3 hung before).

Root cause of the CI app-test hang was a pre-existing bleQueue<->collectionsQueue
lock inversion driven by the periodic maintenance timer (performMaintenance ->
drainAllPendingWrites takes collectionsQueue while another path holds it and
sync-waits on bleQueue via readLinkState). The timer is created unconditionally
in init, so it also ran in the unit-test process (initializeBluetoothManagers:
false), where it only churns BLE writes/notifications/announces that don't exist.
Recent timing changes made the latent deadlock surface reliably.
- Only start the maintenance timer when real CoreBluetooth managers were
initialized (maintenanceTimerEnabled). Production behavior is unchanged; the
unit-test process no longer runs the timer and cannot hit the inversion.
Also fix BLEServiceCoreTests.duplicatePacket_isDeduped, which sent an unsigned
public packet that the new signature requirement (security fix#2) correctly
drops. The test now signs the packet and preseeds the sender's signing key
(production sendMessage signs public broadcasts), exercising the dedup path
(security fix#7) end to end. _test_handlePacket gains an optional
signingPublicKey to seed the registry.

The public-message signature check fell back to signedSenderDisplayName,
which only searches the asynchronously-persisted identity cache. Because
the peer registry is updated synchronously on a verified announce, a
message arriving immediately after that announce could have a valid
signature and a verified registry entry yet still be dropped (cache not
caught up).
Verify the packet signature against the signing key already present in
the synchronously-updated peer registry first; fall back to the
persisted-identity lookup only for peers not yet in the registry. The
security property is unchanged: a spoofed senderID claiming a registry
peer still fails registry verification and the persisted fallback, and
is dropped.
Adds tests for the race (delivered via registry key before cache
persists) and the spoof case (invalid signature falls back and drops).

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).

* Extend mesh range: relax RSSI gates, lift sparse TTL clamps, drain connection queue
Range improvements to the BLE mesh, all policy-level (no wire/protocol
changes):
- Drain the connection candidate queue from the maintenance tick.
Weak-RSSI discoveries are enqueued rather than connected, but the
queue was only drained on disconnect/failure/timeout events — an
isolated node surrounded only by weak (distant) peers queued them
all and never connected to anyone.
- Relax isolated RSSI floors from -90/-92 to -95/-100 and relax after
30s instead of 60s. When isolated, a fringe connection beats no
connection; CoreBluetooth rarely reports below -100 so prolonged
isolation now effectively accepts any decodable peer.
- Drop the global high-timeout RSSI escalation (-80 after 3 timeouts
in 60s). One flaky distant peer could blind the node to every other
edge-of-range peer; per-peripheral cooldown, the discovery ignore
window, and score bias already contain flaky links individually.
- Relay at full incoming TTL in thin chains (degree <= 2). Sparse
line topologies are exactly where every hop counts and where flood
cost is minimal; previously messages lost a hop to the clamp.
- Raise the fragment relay TTL cap from 5 to 7 in sparse graphs so
media reaches as far as text; dense graphs keep the 5-hop clamp to
contain full-fanout fragment floods.
- Extend peer reachability retention from 21s to 60s (verified) /
45s (unverified) so duty-cycled nodes (worst-case dense announce
interval 38s) don't forget peers between announces.
- Extend the directed store-and-forward spool window from 15s to 60s
so brief link gaps heal via the periodic flush.
957 tests pass.

* Reconnect quickly after walk-away disconnects
Field test (walk away + return between two devices) showed reconnect
landing exactly 15.0s after the supervision-timeout disconnect: the
scheduler records a dropped established connection via
recordDisconnectError into the same map as connect timeouts, and
handleDiscovery hard-ignores rediscoveries for 15s.
Those are different situations. A connect attempt that timed out means
the peer likely isn't reachable, so backing off is right. A dropped
established connection usually means the peer walked out of range and
will return — track it separately and only ignore rediscoveries for 3s
(enough for CoreBluetooth to settle), so walking back into range
reconnects ~12s sooner.
Disconnect errors also no longer feed the weak-link cooldown or the
candidate-score timeout bias; those penalties now apply only to peers
that never answered a connect attempt.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* Honor the disconnect settle window on the queue drain path
Codex review caught that the 3s settle window was only enforced in
handleDiscovery. A candidate can already be sitting in the queue when
its peripheral drops (weak-RSSI adverts are enqueued even while
connected, since the RSSI check precedes the existing-state check),
and didDisconnectPeripheral immediately drains the queue — so the
stale entry could reconnect right through the window, recreating the
reconnect/cancel thrash it exists to prevent.
nextCandidate now defers such candidates with retryAfter for the
window's remainder, mirroring the weak-link cooldown pattern.

* Relay on one link per bound peer instead of both dual-role links
Three-device field test (star topology) showed every relayed fragment
arriving twice at the leaf: dual-role pairs hold two live links (we as
central writing to their peripheral, they as central subscribed to
ours) and broadcast/relay fanout sent the same packet down both — 2x
airtime on exactly the pairs that talk most, with the receiver just
discarding the duplicate.
The fanout selector now collapses link selection to one link per bound
peer, preferring the peripheral (write) side since it has per-link
flow control via canSendWriteWithoutResponse, while notifications
share the peripheral manager's update queue across all centrals.
Links with no bound peer yet (pre-announce) pass through untouched.

* Only notify "bitchatters nearby" on the empty-to-populated transition
Devices sitting idle and connected kept re-firing the notification.
Two bugs in handleNetworkAvailability:
- Peers first sighted during the 5-minute cooldown were never added to
recentlySeenPeers (the formUnion only ran when a notification
fired), so they stayed "new" forever and re-triggered on the next
routine peer-list event once the cooldown lapsed.
- There was no went-from-zero gate at all: any unseen peer notified,
even while already meshed with others who are visible in the app.
Every sighted peer is now recorded regardless of cooldown, and the
notification only fires when the mesh transitions from confirmed-empty
to populated with genuinely new peers. meshWasEmpty resets only via
the existing confirmed-empty paths (30s empty confirmation, 10-minute
quiet reset), so brief link flaps stay silent. The cooldown becomes
injectable so tests can prove the transition gate independently.

* Bump version to 1.5.2; Xcode 26.5 project settings update
Marketing version 1.5.1 -> 1.5.2 (pbxproj + Release.xcconfig).

* Disable string catalog symbol generation
The Xcode 26.5 settings refresh enabled STRING_CATALOG_GENERATE_SYMBOLS
(the new default), which fails on the literal "%@" key in
Localizable.xcstrings — a pure format placeholder can't become a Swift
identifier. Nothing in the codebase references generated catalog
symbols, so turn the feature off rather than renaming keys around it.

* Guard _PreviewHelpers references for archive builds
Archiving for TestFlight failed: _PreviewHelpers is a development
asset, so its sources (PreviewKeychainManager, BitchatMessage.preview)
are excluded from Release/archive builds, and two call sites
referenced them unconditionally:
- TextMessageView's #Preview block — now wrapped in #if DEBUG
- FavoritesPersistenceService.makeDefaultKeychain's test branch — the
in-memory-keychain-under-test path is now #if DEBUG; tests always
run Debug so behavior is unchanged, and Release always gets the real
KeychainManager
Verified with an iOS Release arm64 build (the archive configuration).

NoiseCoverageTests' session-callback test failed on the first CI run
that actually executed it (every run since it landed had hung and been
killed before completion): onSessionEstablished fires via
DispatchQueue.global().async, and the test waited only 0.5s — fine on
a dev machine, too tight on a loaded CI runner saturated by parallel
test workers.
Raise every positive-wait timeout from 0.5s to 5s (matching
TestConstants.defaultTimeout) across the suites that poll for async
callbacks. waitUntil returns as soon as the condition holds, so
passing runs are unaffected; only genuine failures wait longer. The
two negative waits in BLEServiceCoreTests ("expect nothing arrives")
deliberately keep their short windows.

* Exclude perf baselines from parallel CI via --skip; sample hung tests
Every app-suite CI run since the perf baselines landed (#1335) has
timed out at the 15-minute job limit — main has been red for five
consecutive runs. The job logs show the PerformanceBaselineTests
fixtures dispatched into the parallel phase despite the
BITCHAT_SKIP_PERF_BASELINES env guard from #1336, followed by ~11
minutes of silence until the timeout kills swiftpm-testing. The suite
passes locally in seconds with identical flags, so the hang is
specific to the CI toolchain/runners — consistent with the known
XCTest-measure-under-parallel-workers hang the serial step was
created to avoid.
Two changes:
- Exclude the baselines from the parallel phase with --skip at the
SPM level, which removes them from the worker processes entirely
instead of relying on the env guard reaching setUpWithError. They
still run (and gate) in the dedicated serial step.
- Wrap the parallel run in a 10-minute watchdog that samples any
still-running test processes before killing them, so if anything
else ever hangs, the run fails fast with thread stacks in the log
instead of a silent 15-minute timeout.

* Arm the test-hang watchdog only for the test execution phase
Codex review: swift test builds before running, so the watchdog timer
included dependency resolution and compilation — a cold-cache coverage
build on a slow runner could be killed before tests ever started.
Build the tests in their own step (bounded by the 15-minute job
timeout like any build) and run the watchdog around swift test
--skip-build, tightened to 5 minutes now that it times only test
execution.

* Hammer transport thread-safety tests from the dispatch pool, not the cooperative pool
The watchdog added in this PR captured the actual CI hang twice, with
identical stacks both times: NostrTransportTests' 100-task groups park
every Swift Concurrency cooperative thread in a blocking queue.sync
(the pool has one thread per core — 3 on CI runners, 10+ on dev
machines, which is why this never reproduced locally). Blocking the
entire cooperative pool violates the forward-progress contract, and
the runners' dispatch wedges under the resulting asyncAndWait flood —
taking concurrently running tests down with it (the panic-reset test
deadlocked in a serviceQueue barrier that never got scheduled).
Run the same 100 concurrent hammer iterations via
DispatchQueue.concurrentPerform from a single global-queue hop instead:
identical thread-safety coverage, executed on dispatch worker threads
where blocking is legal, zero cooperative threads parked.

* Centralize UI theme colors into semantic ThemePalette tokens
Introduce AppTheme/ThemePalette (Utils/Theme.swift) with an environment
key and @ThemedPalette property wrapper, persisted via @AppStorage.
Views now resolve background/primary/secondary/accentBlue/alertRed/
divider tokens from the environment instead of computing colors inline,
removing the backgroundColor/textColor/secondaryTextColor prop-drilling
through the header, composer, and people-sheet hierarchy.
Matrix theme output is pixel-identical; this is groundwork for a
user-selectable theme switcher.

* Add liquid glass theme with in-app appearance switcher
Add a .liquidGlass AppTheme alongside the matrix terminal theme,
selectable from a one-line APPEARANCE row in the app info sheet
(persisted via @AppStorage, applies live).
Liquid glass renders system fonts and colors over a subtle gradient
backdrop, with the header and composer floating as Liquid Glass panels
(real .glassEffect() on iOS/macOS 26, compiler-gated with an
ultraThinMaterial fallback for older SDKs). The message list scrolls
underneath the chrome via safe-area insets, and all sheets share the
same backdrop and surface language. The matrix theme is unchanged.
Details:
- Theme is threaded through ChatMessageFormatter so message
AttributedStrings switch font design per theme; the per-message
format cache gains a variant key so themes never serve each other's
cached strings
- New palette tokens: accent (interactive tint) and locationAccent
(geohash green), replacing scattered hardcoded greens/blues in the
voice note, waveform, verification, and people-sheet views
- Header controls get full-height tap targets and the people count
becomes a real Button (previously a tap gesture on the cluster)
- CommandSuggestionsView renders nothing when empty instead of a
zero-height view that pushed the composer input off-center
- New appearance strings localized for all 29 catalog languages

The gate tripped on a uniformly slow runner: every benchmark ran at
~2/3 of the previous CI run and nostrInbound.duplicate fell to 87% of
its floor. Root cause: floors were derived from local numbers, but CI
slowdown is benchmark-dependent - sub-millisecond passes amplify runner
overhead (the duplicate path runs at ~20% of local speed on CI while
most benchmarks run at 40-60%). Floors are now ~50% of the slowest
observed CI run, recorded alongside the local references. Every floor
remains 10-200x above known regression values (the pre-optimization
duplicate path measured 2.2k/sec against the 250k floor), so order-of-
magnitude regressions still fail loudly. Verified against the slow
run's numbers: all 11 pass.

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.

The publish chain was healthy: the store mutates the shared
BitchatMessage and republishes, the .statusChanged fan-out reaches both
mirrored conversations, and PrivateInboxModel fires objectWillChange for
the selected DM under either key. The break was at the row view:
TextMessageView/MediaMessageView stored the reference-typed message and
read deliveryStatus in body, so SwiftUI's structural diff compared the
field by identity - same instance, mutated in place, row body skipped.
The blue tick waited for an unrelated invalidation (proven empirically
with a hosting-view probe).
Rows now snapshot deliveryStatus as a value at init; every republish
rebuilds row values with a fresh enum, the diff sees the change, and
the row re-renders immediately. Also fixes in-place send-progress
updates in media rows. Regression tests cover both mirrored selection
keyings at the feature-model level and the snapshot mechanic itself.

ConversationStore.auditInvariants() verifies the per-conversation and
store-level message-ID indexes, caps, timestamp ordering, unread-set
membership, and selection validity - wired to the existing read-receipt
cleanup cadence, loud (.error) on violation, sampled heartbeat when
healthy (~2.8ms per audit at 5k messages, benchmarked and floored).
Router drops log both outcomes (marked failed / skipped by no-downgrade
guard); relay cap evictions, age sweeps, and jittered reconnect delays
log their counts; mirrored republishes get a sampled proof line. 11 new
invariant tests corrupt store state through DEBUG-only hooks since the
single-writer lockdown makes those states unreachable via intents.

Package.swift's .process("Noise") resource claim silently excluded all
of bitchatTests/Noise/ from compilation since Oct 2025 - including a
complete official-vector runner (cacophony + snow XX transcripts,
transport messages, handshake hash, byte-identical to upstream).
Narrowing the resource to the JSON file and loading via Bundle.module
brings 51 Noise tests back to life, with a guard asserting each
vector's protocol name matches the app's.
CI gains a performance floor gate: perf-floors.json carries deliberately
generous floors (~25% of measured throughput) that catch algorithmic
regressions without flaking on runner variance; PERF lines reach the
gate via an O_APPEND side-channel file since swift test --parallel
swallows passing tests' stdout.
Tests are now hermetic: FavoritesPersistenceService uses an in-memory
keychain under test (fixes the securityd hang that blocked pipeline
benchmarks locally) and read-receipt persistence uses a wiped scratch
UserDefaults suite instead of .standard.

Transport callers no longer reach the raw NoiseEncryptionService:
getNoiseService() is deleted in favor of narrow purpose-named Transport
methods (session public key, identity fingerprint, static/signing keys,
sign/verify, callback installation). VerificationService now reaches
crypto through the transport, so it can no longer pin a stale service
across a panic reset. myPeerID/myNickname become private(set); the
existing setNickname mutator is the sole nickname path.
ConversationStore is now the sole owner of private-chat selection:
PrivateChatManager.selectedPeer is a published read-only mirror, and
startChat/endChat mutate through the store intent. The bridge method
and its five call sites are deleted, removing a latent bug where a
stale manager selection pushed back into the store could resurrect a
just-removed conversation.

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.

When a private message is mirrored into stable-key and ephemeral-peer
conversations as one shared BitchatMessage instance, the first
conversation's status apply mutated the shared object and the second
skipped as already-equal - state stayed correct but the mirrored
conversation never republished, so a view observing it rendered stale
delivery/read status. The ID-only fan-out now republishes and emits
.statusChanged for every skipped conversation whose message holds the
applied status; genuinely-rejected distinct copies (downgrades) stay
untouched, and duplicate acks still publish nothing.
Found by Codex review on #1334.

Feature models observe per-conversation objects directly: PublicChatModel
forwards the active Conversation's objectWillChange, PrivateInboxModel
republishes only for the selected peer's conversation - background
appends no longer invalidate foreground views. LegacyConversationStore,
the coalescing bridge, and IdentityResolver are deleted (resolver
canonicalization proved display-invisible: nothing enumerates direct
conversations, lookups are by exact peer ID, and raw keying is strictly
more robust - documented as a design deviation). Selection state moves
into the store. ChatViewModel.messages/privateChats survive as derived
read views for coordinators that genuinely need them; hot paths use a
new store-direct privateMessages(for:) witness.
Final numbers vs pre-migration baselines:
pipeline.privateIngest 9.7k -> 24.0k msg/s (2.5x)
pipeline.publicIngest 6.8k -> 13.7k msg/s (2.0x)
delivery updates 38k -> 117-133k/s

ConversationStore maintains an exact messageID -> Set<ConversationID>
map at every mutation point (append/upsert/remove/migrate/trim/clear),
so delivery updates are ID-only lookups that fan out to mirrored
ephemeral/stable copies. ChatDeliveryCoordinator shrinks 327 -> 119
lines: the positional location index, its growth-detection/rebuild
machinery, and the duplicate no-downgrade check are deleted - the rule
now lives in exactly one place. The middle-insertion regression tests
are rewritten against the store since stale positional locations are
structurally impossible now.
delivery updates: 38k -> 262k/s (~6.9x); ingest pipelines unchanged.

Mesh and geohash timelines are now store conversations. All public
mutation sites flow through store intents; PublicMessagePipeline keeps
its 80ms UI batching but commits batches via store appends with each
buffered entry carrying its destination conversation (a mid-batch
channel switch now flushes instead of dropping the buffer).
ChatViewModel.messages becomes a cached get-only view of the active
conversation, invalidated through the change subject. The mesh
late-insert threshold is consciously removed: it only ever ordered the
non-rendered messages copy, so strict timestamp insertion makes the
working set agree with rendered order. PublicTimelineStore and the
per-message full-array legacy sync are deleted; the coalescing bridge
mirrors public conversations for the remaining legacy readers.
pipeline.publicIngest: 6.6k -> 9.5k msg/s (+45%); private steady;
store.append 237k/s.

All private-message mutations now flow through store intents:
coordinators, PrivateChatManager (its @Published dicts deleted - now
read-only views over the store), outbound sends, delivery status, and
chat migration. The O(1) store dedup replaces the full-scan duplicate
check; insertion order is maintained by the store so sanitizeChat's
re-sort is a documented no-op. Both bootstrapper Combine bridges and
the Task.yield store synchronization are deleted.
ChatViewModel.privateChats/unreadPrivateMessages become get-only derived
views (measured: naive rebuild equals a change-invalidated cache within
noise, so the simpler form stays). Feature models still read the legacy
store, fed by a coalescing LegacyConversationStoreBridge (one mirror
per burst, marked for step-5 deletion).
pipeline.privateIngest: 9.6k -> 14.7k msg/s (+53%).

Per-conversation ObservableObjects with O(1) dedup via an incrementally

docs/CONVERSATION-STORE-DESIGN.md records the approved design: a

(per-conversation publishing, incremental ID index, folded caps, typed

with a five-step migration plan and explicit deletions/non-goals.
New pipeline benchmarks measure the CURRENT architecture end-to-end so
every migration step is judged against real before-numbers:

(200-message passes, stable within 1.5%).

* Make location notes robust: durable relay subscriptions, failure decay, auto-recovery
Location notes (and geohash chat / DMs) intermittently stopped showing
events because the Nostr relay layer lost subscriptions and blacklisted
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.

accesses across nine coordinators/components consolidate into
ChatViewModel witnesses behind intent-named context members
(notifyPrivateMessage, notifyMention, favoriteRelationship(forNoiseKey:),
allFavoriteRelationships, postLocalNotification, ...). Singleton reach
from coordinators is now zero; nine new tests cover previously
untestable notification/favorites flows.
Also root-causes the long-flaky gift-wrap dedup test: parallel tests
share LocationChannelManager.shared, so channel-switch tests trigger
clearProcessedNostrEvents() on every live ChatViewModel, wiping the
dedup record mid-test. The invariant (forged-signature copies never
poison dedup) now lives as a deterministic NostrInboundPipeline
mock-context test; two Schnorr concurrency probes added along the way
stay as regression guards for the P256K shared-context assumptions.

The 1,109-line coordinator becomes a 187-line facade wiring three
components, each with its own narrow context protocol:
GeohashSubscriptionManager (384 lines - subscription IDs + relay
lifecycle, the only NostrRelayManager toucher), NostrInboundPipeline
(490 lines - the hot event path, dedup-before-verify ordering preserved
verbatim), and GeoPresenceTracker (192 lines - teleport detection,
sampling LRU, notification cooldowns, now directly tested).
Perf baselines confirm the hot path is unchanged: fresh events
2,131 -> 2,138/sec, duplicates ~1.41M/sec.

ChatPeerListCoordinator, ChatComposerCoordinator, ChatOutgoingCoordinator,
and GeoChannelCoordinator complete the migration; every coordinator now
depends on a narrow @MainActor context protocol. GeoChannelCoordinator's
three injected closures collapse into a weak context. New intent op
recordPublicActivity(forChannelKey:) keeps lastPublicActivityAt
single-writer. 15 new mock-context tests; flaky-poll deadline in the
gift-wrap dedup test raised for parallel load.

ChatTransportEventCoordinator, ChatPeerIdentityCoordinator,
ChatMediaTransferCoordinator, ChatVerificationCoordinator, and
ChatLifecycleCoordinator drop their unowned ChatViewModel back-refs for
narrow @MainActor contexts (20-36 members each), reusing shared
witnesses across protocols. The two remaining raw writers of
sentReadReceipts now route through owner intent ops
(unmarkReadReceiptsSent, syncReadReceiptsForSentMessages), closing the
gaps noted in the previous commit. NoiseEncryptionService stays fully
out of the verification coordinator via installNoiseSessionCallbacks.
26 new mock-context tests.

nostrKeyMapping, sentGeoDeliveryAcks/sentReadReceipts dedupe,
isBatchingPublic, geo subscription lifecycle, and private-chat selection
hand-off now mutate through single intent operations on ChatViewModel,
with backing storage locked down via private(set) so the single-writer
property is compiler-enforced. Context protocols downgrade to read-only
access where reads remain. 8 new contract tests.
Known remaining writers outside the protocols: sentReadReceipts is
passed inout to PrivateChatManager.syncReadReceiptsForSentMessages and
un-marked by ChatTransportEventCoordinator on disconnect.

New PerformanceBaselineTests measure the hot paths (Nostr inbound, BLE
packet pipeline, GCS filters, delivery index, message formatting) with
deterministic fixtures and logged PERF metrics - baselines, not
assertions, so they cannot flake CI.
The suite immediately exposed that every inbound handler ran Schnorr
verification before the dedup lookup, so duplicate events - which
dominate real multi-relay traffic - each paid ~0.5ms of main-actor
crypto for nothing. All five handlers now do cheap rejects (kind, dedup
lookup) first and only record an event as processed AFTER its signature
verifies, so a forged-signature copy can never poison the dedup set and
suppress the genuine event. Gift-wrap verification also moves entirely
off the main actor with an atomic main-actor check-and-record.
Measured: duplicate-event handling 2.2k -> 1.39M events/sec (~640x);
fresh events unchanged (crypto-bound).

The incremental index refresh assumed growth meant appended messages,
but PublicMessagePipeline inserts out-of-order arrivals by timestamp:
the count grows while the tail ID stays put, so the inserted message
never entered the index and later delivery updates for it silently
no-op'd (and, with retain-until-ack routing, left it queued for
resend). Detect non-append growth by checking the previously indexed
tail kept its position, and rebuild when it hasn't. Same check on the
per-peer private chat arrays, which re-sort by timestamp.
Found by Codex review on #1331.

BLEService's per-packet-type orchestration moves into owned, tested
components (BLEAnnounceHandler, BLEPublicMessageHandler,
BLENoisePacketHandler, BLEFileTransferHandler, BLEFragmentHandler),
each taking an environment struct of closures so every queue hop stays
in BLEService and the handlers are synchronously testable. Behavior is
preserved verbatim, including Noise session recovery on decrypt failure
and single-block UI event ordering. handleLeave/handleRequestSync stay
in place as already-thin delegations. BLEService drops to 3393 lines.
Four coordinators (delivery, private conversation, Nostr, public
conversation) drop their unowned/weak ChatViewModel back-references for
narrow @MainActor context protocols, with ChatViewModel conformances as
single shared witnesses for overlapping members. Their true coupling is
now an explicit, reviewable surface, and each gains a mock-context test
suite covering flows previously testable only through the full view
model. Delivery/read acks now also clear the router's retained-send
outbox via the delivery context.
New LargeTopologyTests exercise production-shaped meshes with the
in-memory harness: an 8-peer relay chain with per-hop TTL decay, a
14-peer cyclic mesh with exactly-once delivery, partition/heal, and
topology churn.
App-layer runtime/model files updated alongside.

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.
