* 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.

* 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.

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.

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.

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.

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).

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.

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.
