Fixes the prekey-bundle PR review + CI failure:
- CI root cause: the receive queue (mesh.message) is concurrent, so a
gossiped prekey bundle can be processed before the announce that binds
its owner's signing key. The old handler dropped such bundles outright,
so under CI parallel load the bundle was permanently lost and the
cache/gossip tests flaked (verifiedBundleEntersGossipStore,
prekeySealedMailTravelsViaCourierAndOpens). Bundles that arrive before
their binding are now retained per-owner (bounded) and re-attempted when
the verified announce lands, atomically to avoid a check-then-act race.
- Authenticate the OUTER prekey-bundle packet (Codex P2 / review MEDIUM):
require senderID == PeerID(bundle.noiseStaticPublicKey) and verify the
packet's Ed25519 signature (covers senderID + timestamp) against the
owner's bound signing key, in addition to the inner bundle signature.
Stops replay under a fresh timestamp / fake senderID.
- Key the gossip prekey-bundle store/dedup by the bundle's authenticated
identity (noiseStaticPublicKey), not the unauthenticated packet
senderID, so one valid bundle sprayed under many fabricated sender IDs
can't multiply entries and exhaust the 200-owner cap.
- Bump published-bundle generatedAt strictly on consume (Codex P1):
consuming a prekey shrinks the published bundle, so it now republishes
with a strictly newer generatedAt and re-gossips, so peers replace the
cached copy and stop assigning the consumed ID before its 48h grace.
- Guard the panic/clear detached Application Support tree-deletes behind
TestEnvironment.isRunningTests: the SPM test process shares that tree,
so the wipe could land mid-test and flake file-dependent tests.

Stable/verified private chats address a peer by its full 64-hex Noise
key, but the Noise session, advertised capabilities, and connection state
are keyed by the short (SHA256-derived 16-hex) routing ID. sendFilePrivate
resolved the Wi-Fi bulk SendCandidate with the raw peerID, so a 64-hex key
made hasEstablishedSession return false; shouldOffer never selected Wi-Fi
and a >BLE-cap payload cancelled as "Wi-Fi unavailable" even when the
direct peer advertised .wifiBulk.
Normalize with peerID.toShort() once before the session/capability checks
(extracted into wifiBulkSendCandidate) and use the normalized ID for the
negotiation packet and the BLE fallback too.
Test: eligibility + offer path resolves when addressed by a 64-hex Noise
key — the session is established under the short ID, the raw-key lookup
misses it, and the normalized send path still offers Wi-Fi.

Addresses the Codex review and adversarial-review findings on #1383:
- TLV encoding now throws GroupTLVError.valueTooLong instead of clamping to
65535 and truncating, so an oversize group message fails to seal and
surfaces send_failed rather than shipping ciphertext recipients drop.
- Roster nicknames truncate on a Character boundary (never mid-scalar), so a
multi-byte nickname can no longer make the whole signed roster undecodable.
- Invites now bump the epoch (rotate the key) like removals, giving every
roster change a strictly-increasing epoch so out-of-order invite states no
longer last-writer-wins a just-added member back out.
- Removing a member now sends them a creator-signed roster-without-them under
a throwaway all-zero key (never the rotated key), so their client
deactivates the group and surfaces "removed" instead of going silently dark.
- /block is enforced in the group receive path: a blocked member's messages
are dropped from display and notifications, consistent with every other
inbound path.
- Media affordances are disabled in group chats (both computed sites) so the
composer can't strand a media placeholder that never sends; media-in-groups
is a documented v2 item.
- Creator signature now covers the group name and the sender signature covers
the epoch (wire-format-affecting; needs Android parity before ship).
- Explicit isGroup guard in markPrivateMessagesAsRead so read/delivered
receipts can never leak into group conversations under a future refactor.

Two fixes for PR #1380 review findings:
1. CI "Run Swift Tests (app)" hang (exit 137): the new
SecureIdentityStateManagerVouchTests suite was nonisolated, so Swift
Testing ran its tests in parallel on the Swift Concurrency cooperative
pool. Each test enqueues a queue.async(.barrier) write (setVerified)
and immediately blocks in queue.sync / queue.sync(.barrier)
(recordVouch / effectiveTrustLevel). On CI's few-core runners every
cooperative-pool thread ended up parked behind a pending barrier that
never got a dispatch worker, deadlocking the whole test process until
the watchdog SIGKILLed it. The suite is now @MainActor, matching the
production isolation of the vouch API (ChatVouchCoordinator is
@MainActor) and keeping blocking syncs off the cooperative pool.
2. Codex P2: an open fingerprint sheet did not refresh its vouched badge
when a vouch batch was accepted - VerificationModel.bind() never
observed the trust-change signal. It now subscribes to the
"peerStatusUpdated" notification that
ChatVouchCoordinator.notifyPeerTrustChanged() posts (same source
PeerListModel uses) and forwards it to objectWillChange. Added a
regression test that pins VerificationModel's own subscription
(verified to fail without the fix).

Fixes the confirmed downlink/uplink defects from the PR #1384 review +
Codex findings:
- Downlink age + #g gate (Codex P2 / review #1): rebroadcastRelayEvent
now drops events outside the same freshness window receivers enforce
and whose #g tag mismatches the carrier geohash, BEFORE spending any
budget — so a 1h/200-event channel-resubscribe backfill no longer
burns the 30/min BLE budget on events every receiver drops.
- Rate-limit + dedup before Schnorr (review #2): handleUplinkDeposit now
runs cheap structural checks + carried-ID dedup + rate-token consume
before isValidSignature(), so a replay flood is bounded by cheap work
instead of unbounded main-actor verifies.
- Quota-dropped deposits not rendered (review #3): enqueueUplink reports
acceptance and injectInbound only fires for events actually
published/queued, ending the local-timeline divergence.
- Drain timer + mark-after-send (Codex P2 / review #4): a burst beyond
budget now arms a timer to drain when the window frees; rebroadcast
IDs are marked only after an event is actually sent, so overflow-
dropped events stay retryable.
- Symmetric publish path (review #5): the gateway publish closure now
refuses when no geo relay is known, matching the local send path
instead of publishing dead traffic to default relays.
- Loop-rule doc (review #7): softened to reflect that rule 3 is a
call-site convention with unit-tested backstops; added tests for the
publishedEventIDs backstop, downlink freshness/mismatch, drain timer,
and quota-drop non-injection.

Follow-ups deferred from the REQUEST_SYNC review (#1371):
- SyncTypeFlags.init(rawValue:) now masks to the union of bits that map to a
known message type (derived from the bit↔type table, so it tracks new
types automatically). Phantom bits from a truncated/garbled flags field —
or a type a newer peer added — no longer live in the set as membership no
contains() matches yet toData() re-serializes.
- GossipSyncManager stored each latest announce as (hex-id string, packet)
and diffed announces against the stored string while every other type
recomputed the ID via PacketIdUtil. Collapsed the store to just the packet
and recompute the ID everywhere, removing the latent dual-path divergence.
- Documented the REQUEST_SYNC TLV table and marked fragmentIdFilter (0x06)
with a TODO(v2): it's parsed/re-serialized but never populated or honored
(reserved for incremental fragment sync) — finish or drop, not silent dead
surface.
Adds SyncTypeFlags phantom-bit/round-trip tests and a GossipSyncManager test
that an announce already in the requester's filter is suppressed (guards the
recompute path). Full suite: 1034 tests pass.

BLE stays the control plane: a sender with a queued file > 64 KiB to a
directly connected peer advertising the wifiBulk capability sends a
bulkTransferOffer (0x04) inside the established Noise session — transferID,
file size, payload SHA-256, a fresh 32-byte token, and a random per-transfer
Bonjour instance name. The receiver answers bulkTransferResponse (0x05) with
its own token half, then both sides meet on a per-transfer
_bitchat-bulk._tcp channel over peer-to-peer Wi-Fi (AWDL).
The TCP stream is secured independently of TLS: both tokens traveled inside
Noise, so only the two peers can derive the ChaChaPoly channel key
(HKDF-SHA256, domain "bitchat-bulk-v1", transferID as salt). Frames are
length-prefixed sealed boxes with structured direction+counter nonces; the
first frame must prove knowledge of the key or the client is disconnected,
and the final hash is verified against the offer before delivery.
Decline, timeout, or any mid-transfer error falls back to BLE fragmentation
exactly once, driving the same TransferProgressManager stream so the UI is
unchanged. Wi-Fi-negotiated transfers may carry up to 8 MiB (new
FileTransferLimits.maxWifiBulkPayloadBytes, enforced by the receiver from
the accepted offer); the BLE path keeps its existing caps.

An opt-in "internet gateway" toggle lets one connected phone bridge the
local geohash channel for mesh-only peers: signed kind-20000 events ride
a new nostrCarrier (0x28) packet — directed to the gateway for uplink,
broadcast with TTL for downlink — with Schnorr verification at every
hop, CourierStore-style quotas, and explicit loop-prevention rules.
- BitFoundation: MessageType.nostrCarrier = 0x28
- NostrCarrierPacket: 2-byte-length TLV codec (direction, geohash,
signed event JSON), 16 KiB cap, tolerant decoder
- GatewayService: closure-injected policy layer — verify gates (sig,
kind, #g tag, age, size), uplink quotas (10/min/depositor rate limit,
offline queue of 20 total / 5 per depositor, drop-oldest, flush on
reconnect), downlink budget (30/min, bounded drop-oldest backlog),
bounded loop-prevention ID sets
- BLEService: runtime capability bits (advertise .gateway only while
the toggle is on, re-announce on change), signed directed uplink
sends, carrier ingress with depositor signature verification
- Mesh-only senders uplink automatically from sendGeohash when no relay
is connected and a reachable peer advertises .gateway; once-per-
channel "sent via mesh gateway" notice
- UI: gateway toggle beside the Tor toggle, globe header indicator,
VoiceOver labels, xcstrings entries

Small encrypted crews (hard cap 16) between public broadcast and 1:1 DMs:
Protocol
- MessageType.groupMessage = 0x25: broadcast packets with a cleartext
16-byte group ID + epoch, ChaCha20-Poly1305 ciphertext (epoch bound as
AEAD AAD), inner Ed25519 sender signature over
"bitchat-group-msg-v1"|groupID|messageID|timestamp|content
- NoisePayloadType.groupInvite = 0x06 / .groupKeyUpdate = 0x07:
creator-signed group state (key, epoch, roster) 1:1 over Noise; signature
over "bitchat-group-v1"|groupID|epoch|key-hash|roster-hash and the Noise
session peer must BE the creator
- SyncTypeFlags bit 10 (groupMessage): variable-length LE bitfield widens
1 -> 2 bytes inside the length-prefixed REQUEST_SYNC TLV; old clients
ignore unknown bits and answer with types they know
- PeerCapabilities.localSupported now advertises .groups
Storage
- GroupStore: symmetric keys in the keychain, roster/name/epoch as
protected JSON in Application Support; wiped in panicClearAllData()
Behavior
- Non-members relay 0x25 like any broadcast but cannot read it; group
messages join gossip-sync backfill with the public-message window
- Receivers drop wrong-epoch envelopes, bad sender signatures, and
senders missing from the creator-signed roster
- Fire-and-flood delivery (no per-member acks in v1)
UI
- Groups open as chat windows through the private-chat sheet (virtual
"group_" peer IDs); groups section in the people sheet; /group
create/invite/remove/leave/list commands; invitees get a system message
+ notification and the group appears in their people sheet

Courier envelopes were sealed with one-way Noise X to the recipient's
long-lived static key, so a later compromise of that key exposed every
envelope captured in transit. This adds one-time prekey bundles:
- PrekeyBundle (MessageType 0x24): 8 one-time Curve25519 public prekeys
bound to the owner's Noise static key by an Ed25519 signature over
"bitchat-prekey-bundle-v1" canonical bytes; gossiped mesh-wide on its
own 60s sync round (SyncTypeFlags bit 9, 200-peer cap, 24h freshness)
and verified against the announce-bound signing key before caching.
- Sealed envelope v2: Noise X where the responder static is the one-time
prekey, prologue "bitchat-prekey-v1" || prekeyID. Sender identity rides
encrypted inside and is authenticated exactly like v1 (blocked-sender
check included). CourierEnvelope gains an optional prekeyID TLV that
v1 decoders skip as unknown.
- Local prekeys live in the Keychain; consumed privates survive a 48h
grace window for spray-and-wait redeliveries, then are deleted (the
forward-secrecy clock starts at deletion). The batch tops back up and
re-gossips when unconsumed count drops below 3, and everything is
wiped in panic mode.
- Routing: courier sealing picks a cached verified bundle when one
exists (one prekey per message, reused across deposit retries), with
the advertised .prekeys capability as a veto for on-mesh peers, and
falls back to static sealing otherwise.

When a Noise session establishes with a peer I verified and that peer
advertises the .vouch capability, send signed attestations (up to 16,
most recently verified first, at most once per peer per 24h) for the
OTHER fingerprints I verified. Receivers accept vouches only from
senders they verified themselves, verify the Ed25519 signature against
the sender's announce-bound signing key, and surface the result as a
new derived trust tier: vouched (unfilled seal) between casual and
trusted.
Protocol:
- NoisePayloadType.vouch = 0x12 carries a batch of TLV attestations:
voucheeFingerprint (32B), voucheeSigningKey (32B), timestamp
(uint64 ms BE), Ed25519 signature over
"bitchat-vouch-v1" | fingerprint | signingKey | timestamp.
The voucher is implicit in the authenticated session.
- PeerCapabilities.localSupported now advertises .vouch.
Storage (SecureIdentityStateManager / IdentityCache):
- vouches keyed by vouchee, capped at 8 vouchers each; validity is
recomputed on read (voucher still verified-by-me, < 30 days old), so
unverifying a voucher retires their vouches without cascade deletes.
- New IdentityCache fields are Optional so pre-existing encrypted
caches decode cleanly; TrustLevel.vouched is inserted mid-ladder but
raw values are strings, so persisted values are unaffected (and
vouched itself is never persisted).
- Panic wipe clears vouch state with the rest of the identity cache.
UI: unfilled checkmark.seal badge in the mesh peer list (filled seal
stays exclusive to verified) and a "vouched for by N people you
verified" section with voucher names in FingerprintView; VoiceOver
labels and xcstrings entries included.
Tests: attestation encode/decode + signature (forged/tampered/expired),
accept-policy gates, batch cap, trust-level derivation incl. voucher
invalidation, persistence compat, and coordinator exchange/accept
policies. Full macOS suite: 1088 tests passing.

Announces now carry an optional capabilities TLV (0x05): a little-endian
bitfield with named bits for upcoming features (prekeys, wifiBulk,
gateway, groups, board, vouch, meshDiagnostics). Old clients skip the
unknown TLV; peers without it decode as nil so features can distinguish
"legacy peer" from "advertises nothing".
PeerCapabilities lives in BitFoundation with a minimal-length encoding
that preserves unknown bits for forward compatibility. Peer capabilities
are stored in the BLE peer registry on verified announce and exposed via
BLEService.peerCapabilities(_:). The local advertisement set is empty
until each feature ships its bit.

Store-and-forward previously delivered to an out-of-range peer only if a
mutual favorite happened to be connected at send time and later met the
recipient directly, and everything except courier envelopes died with the
app process. This closes those gaps end to end:
- Persist the MessageRouter outbox to disk, sealed with a ChaChaPoly key
held only in the Keychain (no plaintext at rest); queued private
messages now survive an app kill and flush on next launch.
- Deposit retry: queued messages are re-deposited whenever a new eligible
courier connects, tracked per message so the same courier is never
double-burned, until 3 distinct couriers carry it or it expires.
- Tiered open couriering: signature-verified strangers can now carry mail
(2 envelopes/depositor into a 20-slot pool) alongside mutual favorites
(5 each); overflow evicts verified-tier mail before favorites'.
- Spray-and-wait: envelopes carry a copy budget (4, capped 8, new TLV,
wire-compatible with old clients); couriers split half their remaining
budget with each newly encountered courier so mail diffuses through a
moving crowd.
- Remote handover: a verified relayed announce now floods a copy toward
the multi-hop recipient (directed-relay treatment, 10-min per-envelope
cooldown) while the carried original stays put for a direct encounter.
- Public history: gossip-sync window for whole public messages widened
from 15 min to 6 h, matched on the receive-acceptance side, and the
message store persists to disk so devices bridge partitions and
restarts ("town crier").
- Privacy-safe local delivery counters (bare tallies, log-only) so the
store-and-forward stack is measurable on-device.
- Panic wipe now also clears the sealed outbox, gossip archive, and
counters.
- Rewrite WHITEPAPER.md to describe the app as implemented (Noise XX/X,
actual flood control, courier system, gossip sync, Nostr path); the old
document described a bloom filter, three fragment types, and a
MessageRetryService that don't exist.
1037 macOS tests pass (17 new); iOS builds.

* Harden REQUEST_SYNC and stop gossip-sync re-send loops
Two fixes from an end-to-end review of the sync path:
Efficiency: the GCS filter (400B, p=7) covers ~355 packet IDs, but stores
hold up to 1000 messages + 600 fragments + 200 files. Once a mesh
accumulates more than the filter can cover, responders re-sent the entire
older tail to every requester every round — ~120KB per pair per 30s during
file transfers, dropped by dedup after the airtime was already burned.
Requesters now stamp the dormant sinceTimestamp TLV with the oldest
timestamp their filter covers, and responders skip older packets (announces
exempt: they carry the signing keys needed to verify everything else).
Periodic sync also sends one request per type schedule instead of a union
filter, so fragment floods can't crowd messages out of the filter budget.
Security: a ~40-byte unsigned REQUEST_SYNC with an empty filter could elicit
a full store replay (~900KB) — an unauthenticated >10,000x amplification
vector, repeatable in a tight loop and relayable with crafted TTL to fan the
drain out of every reachable node. Requests now require ttl == 0, a valid
signature from the claimed sender's announced signing key, and a matching
link binding; REQUEST_SYNC is never relayed regardless of TTL; and responses
are rate-limited per peer (8 per 30s sliding window, ~3x the legitimate
cadence).
Cross-platform: verified against bitchat-android — it signs REQUEST_SYNC and
sends SYNC_TTL_HOPS = 0, so both gates hold; it neither sends nor honors
sinceTimestamp yet, so mixed pairs keep today's behavior with no regression.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* Address Codex review: enforce no-relay on route path, exact since-cursor
Two P2 findings from Codex on the REQUEST_SYNC hardening:
- Route-forwarding bypass: handleRequestSync's early return for a rejected
(nonzero-TTL / unsigned) request still fell through to
forwardAlongRouteIfNeeded, which relays any routed packet with ttl > 1
regardless of type. The no-relay invariant was only enforced on the flood
path. BLERouteForwardingPolicy now suppresses REQUEST_SYNC outright, so a
crafted request with a route and TTL headroom can't be forwarded to the
next hop either.
- Inexact since-cursor: GCSFilter.buildFilter trimmed by hash order when the
encoding overflowed the byte budget, so the cursor (computed from the
untrimmed prefix) could claim coverage of timestamps whose packets were
dropped from the filter — re-sending exactly those every round. buildFilter
now trims from the input tail (oldest, since candidates are newest-first)
and reports includedCount; the cursor is derived from that, so the covered
set is always a contiguous newest-prefix and the cursor is exact.
Adds GCSFilter includedCount coverage (full vs trimmed), a route-forwarding
test for REQUEST_SYNC, and makes the truncated-cursor test robust to trim
variance. Full suite: 1029 tests pass.

* 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.

* 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.

* Make peer lists accessible and actionable; block by stable identity
Who you can reach — the app's most important fact — was encoded in
unlabeled 10pt icons with macOS-only tooltips, and the mesh list had no
actions (block/favorite/verify were slash-command-only).
- Both peer lists become real accessibility citizens: each row is one
element announcing name, reachability, and favorite/unread/blocked
state, with a button trait and custom actions for the gesture-only
interactions. Neither file previously had a single accessibility
modifier. Reachability icons gain tooltips reusing existing strings;
teleported vs in-area pins are explained.
- Mesh rows gain the context menu the geohash list already had: direct
message, favorite, show fingerprint, block/unblock. The fingerprint
double-tap, previously shadowed by the single tap, is reordered so it
fires.
- The DM header's offline state (previously EmptyView — absence of a
glyph as the only signal) becomes a dimmed "offline" tag, and a
geohash DM — always Nostr-routed — no longer mislabels itself
"offline".
- App Info gains a SYMBOLS legend defining every glyph the lists and
headers use; nothing defined them before.
- Mesh block/unblock now resolve by the peer's stable Noise identity
instead of a `/block <displayName>` string, so the exact tapped row is
affected and offline peers can be unblocked (with covering tests).
New strings are added source-language (en) only.
* Surface block/unblock feedback in the conversation where it was triggered
setMeshPeerBlocked silently returned when the peer's identity could not
be resolved (e.g. long-press-blocking an old public message from a
sender who left and was never a favorite), where the /block command
printed "cannot block X: not found or unable to verify identity" — post
that same message from the guard branch.
Both the failure and confirmation messages now route through
addCommandOutput instead of addSystemMessage, so blocking from inside a
private chat prints into that chat rather than invisibly into the
public timeline (same routing #1363 applied to command output).
The confirmation also reuses the /block wording ("blocked X. you will
no longer receive messages from them") for parity with the command.

* Remove dead accessibility label and unreachable /unblock fallback
The favorite button's .accessibilityLabel in MeshPeerList is
unreachable: the row-level .accessibilityElement(children: .ignore)
swallows child elements, and the row's custom accessibility action
already covers favoriting.
ConversationUIModel.unblock is only called from the mesh peer list with
a non-optional mesh peerID, so the "/unblock <name>" fallback branch
could never run — take PeerID directly and drop the branch.

CommandProcessor results (/help text, errors like "unknown command",
/msg confirmations) were always appended to the public timeline via
addSystemMessage, so a command typed inside a DM appeared to do
nothing until the user switched back to the public channel.
handleCommand now routes .success/.error output to the open private
chat when one is selected, falling back to the public timeline
otherwise. The DM selection is read after processing so commands that
switch chats (/msg) print into the conversation they just opened.
Follow-up to #1354, which added /help and surfaced this routing gap.

The autocomplete panel is the only in-app surface for discovering slash
commands, but several suggestions do not match what CommandProcessor
accepts, so tapping them inserts a command that returns "unknown
command":
- CommandInfo suggests /dm, /favorite, /unfavorite, but the processor
only handles /m, /msg, /fav, /unfav. Aliases are aligned to the
accepted spellings (msg, fav, unfav).
- Favorites are suggested only in geohash contexts (isGeoPublic ||
isGeoDM) — exactly where the processor rejects them ("favorites are
only for mesh peers"). The gating is inverted so they appear in mesh,
where they work.
Also, small related fixes to the discovery surface:
- /help is now handled (the ChatViewModel command docstring already
claimed it existed); it prints a local system line listing the valid
commands, and the unknown-command error points at it.
- The suggestion panel keeps the matched command's usage row (e.g.
"/msg <nickname>") visible while arguments are typed, instead of
vanishing at the first space; in that mode the row is informational
and no longer overwrites the draft on tap.
New string is added source-language (en) only. The CommandInfo contract
test is updated to the corrected metadata.
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.

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).
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
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).
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
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.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* 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
maintained message-ID index, binary-search timestamp insertion, folded
cap policies, a no-downgrade delivery rule, and a typed change subject.
All mutation flows through store intents (conversation mutators are
fileprivate). The previous store is renamed LegacyConversationStore
pending deletion in step 5. 16 behavioral tests including per-
conversation publish isolation; store.append benchmarks at ~144k
messages/sec.
