* 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.

* 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).

* 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.

* 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.

* 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.

* DMs to unreachable peers route through store-and-forward; drop stale reachability gates
Field-found: sendPrivateMessage pre-judged reachability and marked the
message failed without ever calling the router, so the retained outbox,
courier deposits, and bridge drops never ran — a DM composed after a
peer's reachability window lapsed was dead on arrival while an identical
one sent a minute earlier delivered. Messages now always route; a live
path earns "sent", everything else stays "sending" until the router
reports carried/delivered or expires it as failed.
A sweep for sibling gates found and fixed:
- startPrivateChat refused offline non-mutual favorites ("mutual favorite
required for offline messaging") — store-and-forward only needs the
recipient's noise key, so the gate and its string are gone.
- markPrivateMessagesAsRead skipped the whole receipt pass for peers
without a stored Nostr key, starving mesh-connected non-favorites; the
router picks the transport now (sentReadReceipts dedups the parallel
PrivateChatManager path).
- DM/geoDM blocked notices and the unknown-group error posted to the
active public timeline; they now land in the thread they're about via
addLocalPrivateSystemMessage.
- Banned copy: literal "user" fallbacks in code become "anon" (the
default-nickname convention), and es/fr/it/pt translations of four keys
still saying usuario/utilisateur/utente/usuário now say person. Orphaned
keys removed (system.dm.unreachable, content.delivery.reason.unreachable,
system.chat.requires_favorite).

* Deflake BLEServiceCoreTests: longTimeout for positive waits
CI flaked on duplicatePacket_isDeduped: the first message landed after the
5s wait expired on a loaded runner (the test's later count==1 assertions
passed, proving late delivery, not lost delivery). All four positive waits
in the file now use TestConstants.longTimeout, which exists for exactly
this — waitUntil returns as soon as the condition holds, so passing runs
never pay the longer ceiling.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* Fix read-receipt test contamination; baseline Periphery noiseKey flake
Two CI failures, both environmental:
- markReadReceiptSent_returnsFalseOnSecondCall flaked because every test
ChatViewModel shared one per-process read-receipts scratch suite; the
lifecycle test persists the same "read-1" ID (a path the receipt-gate
removal now reaches), and test order decided who saw whose state. Each
instance now gets its own UUID-suffixed suite.
- Periphery intermittently misses the loadFromDisk read of
PrekeyBundleStore.StoredBundle.noiseKey and fails --strict with a false
"assign-only" finding (recurrence of a known flake). Its USR is
baselined; an in-source periphery:ignore can't work because strict mode
flags it as superfluous on runs where the indexer gets it right.

* Friend-courier store-and-forward: mutual favorites carry sealed messages to offline peers
When a private message has no reachable transport, the router now seals it
to the recipient's Noise static key (new one-way Noise X pattern) and hands
the envelope to up to three connected mutual favorites. Couriers store the
opaque ciphertext under strict quotas (20 total, 5 per depositor, 16 KiB,
24 h) and hand it over when the recipient's announce matches a rotating
HMAC recipient tag; the recipient opens it and the message flows through
the normal private-message pipeline, so dedup and delivery acks just work.
- CourierEnvelope TLV + courierEnvelope (0x04) message type in BitFoundation
- Noise X one-way pattern reusing the existing handshake machinery,
domain-separated by a courier prologue; sender identity authenticated
via the ss DH (no forward secrecy - documented tradeoff)
- CourierStore with eviction, file persistence, and panic-wipe integration
- Rotating recipient tags (HMAC over epoch day) so carried envelopes don't
correlate for observers who don't already know the recipient's key
- New "carried" delivery status with figure.walk glyph; header indicator
while carrying mail for others
- Three-node end-to-end test ferrying packets through real BLEService
instances, plus codec/crypto/store/router suites (986 tests green)

* Fix courier handoff verification and directed sends
* Authenticate courier deposits by ingress peer
* Gate courier handover on direct announces and isolate store test
Envelopes are removed from the courier store optimistically, so releasing
them on a relayed (multi-hop) announce risks losing carried mail to a
speculative flood that never reaches the recipient. Handover now also
requires the announce to have arrived directly (full TTL), i.e. an actual
encounter with a live link; regression test builds a relayed copy of a
genuinely signed announce (TTL is excluded from announce signatures).
Also make CourierStore's on-disk location injectable so the persistence
test round-trips through a temp directory instead of wiping the real
Application Support store, and reattach BLEAnnounceHandler's doc comment
to the class it describes.

* Use Xcode-bundled Swift in CI instead of a standalone toolchain
The unpinned setup-swift action installs Swift 6.1, which refuses the
SDK on runner images that have rolled to Xcode 26.5 ("this SDK is not
supported by the compiler"). Jobs passed or failed depending on which
image they landed on. The Xcode-bundled toolchain always matches the
image's SDK, and matches local development. Cache keys now include the
toolchain version so artifacts from one compiler are never restored
into builds with another.

* Drop couriered mail from blocked senders at envelope open
The UI-layer block check (isPeerBlocked in the transport event
coordinator) resolves a fingerprint from the live session or peer list,
but a couriered message arrives precisely when its sender is absent —
no session, no registry entry — so the check failed open and a blocked
identity's mail was delivered anyway. Gate in openCourierEnvelope,
where the sealed sender's full static key is in hand.
End-to-end test ferries a full deposit→carry→handover round and
verifies the envelope from a blocked sender never reaches the delegate
(confirmed failing without the gate).

* Fix favorites end-to-end: peer-list dedup, Nostr sync, /fav key corruption
- UnifiedPeerService: dedup offline favorites against mesh peers by noise
key. Phase 2 compared a 64-hex noise-key PeerID against 16-hex mesh IDs
(never equal), leaving only a nickname+isConnected heuristic — a mutual
favorite that was reachable-but-not-connected or renamed rendered twice,
and a same-nick stranger could suppress a favorite entirely.
- Nostr inbound: intercept [FAVORITED]/[UNFAVORITED] markers in the live
PM handler so they update theyFavoritedUs instead of rendering as chat
text; mutual favorites can now form over Nostr. Delete the dead
favorite-aware PM variant and ChatNostrCoordinator.handleFavoriteNotification
(unwired, parsed a stale FAVORITE:TRUE|… format no sender emits).
- NostrTransport.isPeerReachable: match short form regardless of incoming
ID width — toggling an offline favorite (addressed by 64-hex noise key)
was silently dropped with no reachable transport.
- BLEService.sendPrivateMessage: normalize recipient to the short ID like
sendFilePrivate, so a 64-hex target hits the existing Noise session
instead of initiating a handshake with a 32-byte wire recipient ID.
- /fav, /unfav: stop writing Data(hexString: peerID.id) — the 8-byte
routing ID for mesh peers — into the favorites store as a "noise key",
and stop double-sending the favorite notification; delegate to
toggleFavorite with a proper state check.
- FavoritesPersistenceService.updatePeerFavoritedUs: keep the stored
nickname when the caller passes the "Unknown" placeholder.
- Bump marketing version to 1.5.4.

* Route DMs to mutual favorites via Nostr when a mesh-keyed peer goes offline
Field-tested on device: with a DM window opened while the peer was on
mesh (conversation keyed by the short 16-hex ID), walking out of range
and sending failed instantly with "peer not reachable" even though the
header showed the peer as Nostr-reachable (mutual favorite, npub known).
sendPrivateMessage derived the favorites key as Data(hexString:
peerID.id) — for a short mesh ID that is the 8-byte routing ID, never
the noise key — so the mutual-favorite/Nostr-key checks always came up
empty and the send failed before reaching MessageRouter. Conversations
keyed by the full 64-hex noise-key ID (opened from the offline favorite
row) were unaffected, which is why later tests appeared to work.
Resolve the noise key properly (peerID.noiseKey, then the unified peer
row, then the favorites store by derived short ID) and add a regression
test for the mesh-keyed-peer-goes-offline case.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* Label Nostr DMs from favorites with their stored nickname
Field-tested: a DM delivered over the Nostr fallback rendered as
"anon#678e" instead of the sender's name. The inbound handler named the
sender via displayNameForNostrPubkey, which only knows geohash-scoped
names — even though the pipeline had already resolved the sender's
noise key (the conversation is keyed by it).
When the conversation key carries a noise key, prefer the favorite's
stored nickname; geohash DMs (nostr_ keys) keep the anon geo name. This
also stops an inbound Nostr [FAVORITED] from overwriting the stored
nickname with the anon fallback, since the same name feeds
updatePeerFavoritedUs.

* Fix courier path for offline favorites addressed by noise-key IDs
Two Codex review findings, both the same ID-width confusion this PR
targets, in the courier flow:
- CourierDirectory.favoritesBacked resolved recipients only via
getFavoriteStatus(forPeerID:), which requires a short 16-hex ID —
offline favorites are addressed by the full 64-hex noise-key ID, so
attemptCourierDeposit silently bailed for exactly the peers couriers
exist to serve. The 64-hex ID now yields its own key directly.
- openCourierEnvelope emitted the derived short mesh ID even when the
sender has no live mesh identity, landing couriered mail in an
unresolvable short-ID thread labeled "Unknown". Absent senders now
emit the full noise-key ID so the message joins the stable favorite
conversation; present senders keep the live short-ID thread.

Four spurious CI failures on July 5, all loaded-runner flakiness:
- ViewSmokeTests.voiceAndMediaViews_renderAndWarmCaches asserted an exact
bin count on WaveformCache.shared for the same URL the mounted
VoiceNoteView was concurrently warming at its default 120-bin width;
whichever barrier write landed last owned the entry. Probe the cache with
a dedicated audio file no view touches, and purge both URLs. Also replace
the fixed 250ms sleep for loadDuration's background hop with a waitUntil
poll.
- sendImage_privateChatProcessesAndTransfersImage (and its sendVoiceNote /
sendImage siblings) wait on work that hops through Task.detached; the
global executor is shared with every parallel test worker, so a loaded
runner can exceed the 5s wait. Raise those positive waits to
TestConstants.longTimeout (10s) — waitUntil returns as soon as the
condition holds, so passing runs are unaffected.
- subscribeNostrEvent_addsToTimeline_ifMatchesGeohash raced concurrently
running suites (e.g. CommandProcessorTests) on the process-wide
LocationChannelManager singleton: a mid-test channel flip reroutes or
drops the event permanently, so no fixed wait recovers. The wait loop now
re-asserts the channel and redelivers the event on each poll — idempotent
because channel switches clear the processed-event set and the store
dedups by message ID — so interference heals while genuine failures still
time out.
- The performance floor gate failed on a saturated runner
(gcs.buildAndDecode at 85% of floor). check-perf-floors.sh now re-runs
the benchmark suite up to twice when a metric lands below floor,
appending to the same PERF log and keeping each benchmark's best value
across attempts: noise clears on a retry, a real algorithmic regression
fails every attempt. Floors are unchanged and never lowered by the
mechanism; missing-benchmark failures exit immediately without retrying.

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.

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%).

NotificationService.shared and FavoritesPersistenceService.shared
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.

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

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.
