The comment on upsertCryptographicIdentity claimed a legitimately
re-keyed peer could recover via "explicit user re-verification", but no
such path exists: setVerified does not reset the signing-key pin. State
the actual recovery options — a new noise identity (new peerID) or
clearAllIdentityData.

Root cause of the CI teardown wedge: SecureIdentityStateManager persisted
via fire-and-forget `queue.async(flags: .barrier)` in all ~10 mutating
methods (each doing encrypt + keychain write). This branch moved
`cryptographicIdentities` into the persisted IdentityCache, so the
announce/identity paths and their tests now schedule far more of these
async barrier saves than main ever did. Under `--enable-code-coverage`
(CI only) on the runner's constrained 2-3 cores, that backlog of
INSTRUMENTED fire-and-forget barrier work is still draining when LLVM
writes `.profraw` from its `atexit` handler; the dump deadlocks against
the in-flight instrumented threads -> all tests dispatch, ~5-min wedge,
Killed:9. main and the other PRs pass because they don't add this save
volume; it doesn't repro on an 18-core dev box because the backlog drains
before exit.
Fix (correct-by-construction, no CI-timing repro needed): convert every
mutating method's `queue.async(flags: .barrier)` to
`queue.sync(flags: .barrier)`. When a mutating API returns, the encrypt +
keychain write is already complete and NOTHING is scheduled on the queue,
so teardown/atexit has zero outstanding dispatch to wait on.
Re-entrancy audit (sync barriers deadlock if entered on-queue):
- No mutating method calls another mutating method (or forceSave) from
inside a `queue` block — verified by grep; `saveIdentityCache` is a
private inline helper, not a dispatch, so no nested self-hop exists.
- deinit remains queue-free (direct persist of in-hand state), so no
mutating method is reachable from deinit.
- forceSave already uses queue.sync(.barrier) and is never called from
deinit.
No `_onQueue` helper was needed.
Hot-path: upsertCryptographicIdentity runs on the BLE announce path (off
main, on the message/BLE queue) — a synchronous sub-millisecond keychain
write there is fine (announces are throttle/verified-gated). The other
mutating APIs (setFavorite/setBlocked/setVerified/updateSocialIdentity/
setNostrBlocked) are user-initiated one-shot UI/command actions; a fast
synchronous keychain write is acceptable and not in any hot loop.
Verified: no `queue.async` remains in code (comments only);
`time swift test --parallel --enable-code-coverage --skip
PerformanceBaselineTests` green and exits ~3s after the last test across
repeated runs, including under LIBDISPATCH_COOPERATIVE_POOL_STRICT=1 with
2 workers (~8s, no wedge); ThreadSanitizer clean on the identity +
announce suites; canonical `swift build && swift test --parallel` green.

The two stress tests I added (test_concurrentUpsertsAndForceSaveDoNotRaceOrHang
and test_manyManagersDeinitDoNotWedgeTeardown) spawned units of work that the
test could not deterministically join before returning:
- test_manyManagersDeinitDoNotWedgeTeardown created 200 managers that each
scheduled a fire-and-forget queue.async(.barrier) save on the manager's own
private queue; the test has no handle to await that per-manager barrier work,
so a large backlog of it could still be executing after the test returned.
- test_concurrentUpsertsAndForceSaveDoNotRaceOrHang spawned 32
DispatchQueue.global().async workers, each also scheduling per-manager
barrier saves; the DispatchGroup only joined the worker loops, not the
manager's internal barrier work.
Under --enable-code-coverage (CI only), LLVM writes .profraw from an atexit
handler; if instrumented worker threads are still live during that dump the
process deadlocks at exit — matching the CI signature exactly: all 145 tests
start, then a ~5-minute wedge, then Killed:9. It reproduced only on the
constrained CI runner, not locally (18 cores drained the backlog before exit),
which is why earlier local runs looked clean.
The production fix is already verified: ThreadSanitizer is clean on the
identity + announce-handler suites (no data race, no re-entrant deadlock), and
the deterministic unit tests cover the signing-key pin refusal, persistence
across re-init, and the persisted-pin fallback. A stress test that
destabilizes CI is worse than no stress test, so both are removed along with
the now-unused LockedKeychain double.
Verified: `time swift test --parallel --enable-code-coverage
--skip PerformanceBaselineTests` is green 6x and the process exits ~2.9s after
the last test (tests run in ~1.5s); no teardown wedge under coverage even with
LIBDISPATCH_COOPERATIVE_POOL_STRICT=1 and a single worker.

The previous fix routed forceSave() through queue.async(flags: .barrier),
and deinit called forceSave(). Dispatching onto the private concurrent
queue from deinit is a teardown hazard: the async block resurrects self
and enqueues barrier work that may not drain before process exit, so at
teardown swift-testing/libdispatch waits on that outstanding work and the
process never exits — the CI "Run Swift Tests (app)" job reached
[144/144], then wedged for ~5 minutes and was Killed:9. This surfaced now
because moving cryptographicIdentities into the persisted cache made far
more test-created managers persist on deinit.
Root cause confirmed locally: under LIBDISPATCH_COOPERATIVE_POOL_STRICT=1
(single-worker pool, mimicking a constrained CI runner) the old code
intermittently stalled the whole suite ~15s from deinit-scheduled barrier
work starving the pool; the fix is stable across 14 full coverage+parallel
runs with the process exiting ~3s after the last test.
Fix:
- deinit no longer touches `queue`. Persistence is already durable (every
mutating API persists inline within its own barrier), so deinit only
does a queue-free best-effort flush if `pendingSave` is still set — a
direct read of in-hand state, safe because a deallocating object has no
other live references mutating `cache`.
- forceSave() (lifecycle/app-termination only, never deinit) now uses a
synchronous queue.sync(flags: .barrier): race-free `cache` read on the
barrier context and nothing left scheduled at teardown. No re-entrant
deadlock risk since it is never called from deinit.
Test: test_manyManagersDeinitDoNotWedgeTeardown churns 200 managers that
mutate then deinit and asserts the workload completes promptly; combined
with the existing concurrent race guard (still TSan-clean) this covers the
deinit path. Verified: swift test --parallel --enable-code-coverage green
14x with prompt process exit, and TSan-clean.

The previous commit moved cryptographicIdentities into the persisted
IdentityCache, which made the pre-existing off-queue cache access in
the save path fatal instead of merely racy: forceSave() -> performSave()
read and JSON-encoded `cache` on the caller's thread while a concurrent
`queue.async(.barrier)` writer mutated the same dictionary. ThreadSanitizer
flags this as a data race in saveIdentityCache(), and because JSONEncoder
walks the dictionary storage, an interleaved mutation can spin forever —
which is what hung the CI "Run Swift Tests (app)" job (killed at the
watchdog timeout).
The naive fix (snapshot `cache` under `queue.sync` in forceSave) instead
introduced a deadlock: forceSave() is reachable from deinit, and the
object's final release can run *on* the identity queue (the fire-and-forget
barrier saves capture self), so queue.sync there is a re-entrant same-queue
wait -> SIGTRAP. That matched the intermittent crash the hang investigation
surfaced.
Fix:
- Split persistence into persist(snapshot:) which encodes/seals/writes a
by-value IdentityCache snapshot, decoupled from reading `cache`.
- saveIdentityCache() (only ever called inside a barrier writer) passes
`cache` directly — already serialized, race-free.
- forceSave() now snapshots + persists inside `queue.async(flags:.barrier)`
(async, never sync): the read is on the barrier context so it never races
an in-flight write, and being async it can't deadlock when invoked from
deinit running on the queue. Durability is unaffected: every mutating API
already persists inline within its own barrier, so forceSave is a
belt-and-suspenders flush.
Test: test_concurrentUpsertsAndForceSaveDoNotRaceOrHang hammers concurrent
upserts interleaved with forceSave; it reproduces the data race under
`--sanitize=thread` on the old code (SecureIdentityStateManager.swift:250)
and passes cleanly with the fix. A lock-guarded LockedKeychain double is
used so the test exercises the manager's own cache race rather than the
non-thread-safe MockKeychain. Verified green over repeated
`swift test --parallel` runs both with and without --enable-code-coverage.

The TOFU signing-key pin lived only in the in-memory peerRegistry. When
a previously seen peer was no longer in the registry (app restart, or
reconcileConnectivity pruning an offline peer), the announce trust check
saw no pinned key, treated the announce as first contact, and
persistIdentity overwrote the cached signing key/nickname — so an
attacker could replay a victim's noiseKey/peerID with their own signing
key and bypass the spoofing protection for returning/offline peers.
Fixes:
- BLEAnnounceHandler now falls back to the persisted cryptographic
identity (via a new persistedSigningPublicKey environment closure)
when the registry has no signing key for the peer, so the pin remains
effective across registry eviction and app restarts. BLEService wires
it to SecureIdentityStateManager.getCryptoIdentitiesByPeerIDPrefix,
the same synchronous identity-manager read already used on the packet
path by signedSenderDisplayName.
- SecureIdentityStateManager.upsertCryptographicIdentity refuses to
replace a persisted signing key with a different one (security-logged,
nickname update included in the refusal), mirroring the registry
policy. First-writer-wins persistence also removes any race where a
concurrent announce could poison the stored identity.
- CryptographicIdentity entries (incl. the signing-key pin) are now part
of the encrypted IdentityCache, so they actually persist across app
restarts; previously they were in-memory only. Old caches without the
new field still decode (decodeIfPresent), and clearAllIdentityData /
panic wipe clears the pins as before.
Legitimate re-keying: presenting a different signing key for the same
noise key is exactly the attack being blocked, so refusal is correct
and permanent until the peer adopts a new noise identity (new peerID)
or the user explicitly clears identity data. Repeated rejected announces
follow the existing unverified-announce path (log + ignore); no retry
loops or crashes.
Tests: handler-level persisted-pin mismatch/match/precedence cases, an
end-to-end restart+eviction test with real Ed25519 keys and a real
SecureIdentityStateManager showing the attacker replay is rejected and
the persisted identity is untouched while the victim re-announce is
accepted, and identity-manager tests for the pinned-key refusal and the
keychain round-trip of the pin.

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.

BLE announce trust verified the packet signature against the Ed25519
signing key carried inside the same announce, and the trust policy only
rejected on noise-key mismatch. Since peerIDs derive from the broadcast
(public) noise key, an on-mesh attacker could replay a victim's
peerID+noiseKey with their own signing key, nickname, and a valid
self-signature; BLEPeerRegistry.upsertVerifiedAnnounce then overwrote
the victim's entry unconditionally. That enabled mesh nickname spoofing
and, via the persisted identity, forged attribution of signed
public/broadcast messages.
Fix: TOFU-pin the signing key per peer (noise-key-derived peerID).
- BLEAnnounceTrustPolicy now rejects announces whose signing key
differs from the one already recorded for the peer
(.signingKeyMismatch) and logs a security event.
- BLEPeerRegistry.upsertVerifiedAnnounce refuses to replace a pinned
signing key (returns nil), closing the race where the pre-barrier
trust check reads the registry outside the collections barrier. It
also never drops a pinned key when an announce omits one.
- BLEAnnounceHandler skips registry upsert, topology updates, and
identity persistence for rejected announces.
No wire-format change: the packet signature already covers senderID,
timestamp, and the full announce payload (noise key, signing key,
nickname), so mixed-version meshes are unaffected. First contact for an
unknown peer behaves exactly as before (trust on first use); the pin is
scoped to the registry entry lifetime, so a legitimately re-keyed
identity recovers after normal peer eviction.
Tests: trust-policy signing-key mismatch/match cases, registry pinning
(attacker upsert refused, legitimate re-announce accepted, omitted key
keeps pin), handler-level pinned-key rejection, and an end-to-end test
with real Ed25519 keys showing a fully self-consistent attacker
announce cannot displace the victim's pinned identity.

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).

The app test job hung at process exit (all tests pass, then SIGKILL at the
CI timeout). Root cause: fix#5 replaced the dead Timer.scheduledTimer with
a real DispatchSourceTimer, created per manager instance, resumed and never
cancelled. Those live timer sources kept the dispatch machinery alive so the
swift-testing process never exited. The earlier `isRunningTests` guard was
fragile (it does not reliably detect the swift-testing-only runner on CI).
Drop the debounce timer entirely. Mutations now persist via the same
serialized `queue` barrier their callers already run on (saveIdentityCache ->
performSave directly); forceSave is a direct, non-blocking call (no
queue.sync, which is unsafe on the cooperative pool). No timer is left
scheduled, so nothing keeps the process alive. The original bug is still
fixed — saves now actually happen, unlike the never-firing Timer.

The app test job intermittently hung at process exit. The suite is
load-sensitive and historically prone to cooperative-pool/teardown
deadlocks; the security changes added background work to the test process
that pushed it over the edge. Make the unit-test BLEService/identity
manager quiescent and remove blocking sync:
- forceSave() no longer does queue.sync(.barrier). It is reachable from
deinit and from async tests on the swift-concurrency cooperative pool,
where a blocking barrier-sync can starve/deadlock the pool. It now
cancels the debounce timer and persists directly. (Removed the
now-unneeded queue-specific-key re-entrancy machinery.)
- SecureIdentityStateManager persists synchronously under tests instead of
scheduling a DispatchSourceTimer that lingers past process exit.
- Gate gossip-sync start (in addition to the maintenance timer) behind
real Bluetooth init, so the test BLEService runs no periodic
sign/broadcast/sync churn.
- Skip the panic Nostr reconnect under tests (connecting the shared relay
singleton starts network/reconnect work that never completes).
Production behavior is unchanged: real Bluetooth builds run all timers and
the debounced save as before; the debounce save now actually fires
(previously a Timer on a GCD queue that never ran).

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 forceSave() rewrite used queue.sync(flags: .barrier), but forceSave
is also called from deinit. The debounce timer's barrier hop captured
self strongly, so when that block dropped the last reference the manager
deallocated *on* the identity queue — deinit -> forceSave -> queue.sync
then deadlocked synchronizing onto the queue it was already running on.
This hung the test process at exit (CI SIGKILL / exit 137).
- forceSave() now detects (via a queue-specific key) when it is already
executing on the queue and runs the save directly instead of sync-ing
onto itself.
- The timer's barrier hop now captures self weakly, so it can no longer
trigger a deallocation on the queue in the first place.

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

A broad audit surfaced ten critical/high issues across the crypto,
transport, identity, and panic-wipe layers. This fixes all ten.
Critical:
- Nostr DMs were unauthenticated. The NIP-17 seal was signed with a
throwaway ephemeral key and the receiver never verified it, so anyone
who knows a recipient's npub could forge messages (and delivery/read
receipts) into an existing trusted conversation. The seal is now
signed with the sender's real identity key, and the receiver verifies
the seal signature and that seal.pubkey == rumor.pubkey.
NOTE: this is a breaking wire-protocol change (see PR).
- Public BLE messages trusted registry membership instead of the packet
signature. Since senderID is attacker-controlled, any verified peer
could be impersonated in public chat. A valid signature from the
claimed sender is now required before any registry identity is used.
- Unverified announces still persisted the announced identity, letting a
replayed noisePublicKey overwrite a victim's stored signing key and
nickname. persistIdentity is now gated on verification.
High:
- Noise decrypt trapped on a 16-19 byte ciphertext (negative prefix
length after nonce extraction) — a remote crash. Now validated.
- Identity-cache debounce save used Timer.scheduledTimer on a GCD queue
with no run loop, so it never fired; block/verify/favorite changes
only persisted on explicit forceSave. Replaced with a
DispatchSourceTimer on the queue; forceSave is now serialized.
- Identity-cache key load couldn't tell "missing" from a transient
keychain failure and would regenerate (deleting) the key, orphaning
the cache. Now uses getIdentityKeyWithResult and falls back to a
session-only ephemeral key without clobbering the persisted key/cache.
- BLE receive-dedup key lacked a payload digest, so post-handshake
flushes (queued msgs + delivery/read acks in the same ms) were dropped
as duplicates. Digest added, matching the ingress registry.
- Maintenance timer was created only in init and never recreated after a
panic stop/start, silently degrading the mesh until app restart. Now
recreated in startServices.
- Panic wipe left persisted location state (selected channel, teleport
set, bookmarks) and cached per-geohash Nostr private keys behind. Both
are now cleared.
- Panic spawned an orphan NostrRelayManager instead of reusing .shared,
splitting relay state from every other component. Now reuses .shared.
Tests updated to assert the fixed behavior (announce no longer persists
unverified identities; public messages require a signature; receive
dedup ID includes the payload digest).

* Fix launch crash: recursive dispatch_once between NostrRelayManager and NetworkActivationService
NostrRelayManager.init() runs applyDefaultRelayPolicy(force: true), which
calls dependencies.activationAllowed() when the user has location
permission or a mutual favorite. That closure resolves
NetworkActivationService.shared, whose init captured
NostrRelayManager.shared — re-entering the still-running dispatch_once on
the same thread. libdispatch traps on recursive dispatch_once
(EXC_BREAKPOINT in _dispatch_once_wait), killing the app ~50ms after
launch, before the first frame.
Fresh installs were unaffected (no permission, no favorites, so the
policy path never touched NetworkActivationService during init), which is
why this passed local testing but crashed established TestFlight users on
every launch. Two independent TestFlight crash reports on 1.5.2 (1)
show the identical stack.
Break the cycle by resolving the relay controller lazily: store a
provider closure in init and dereference NostrRelayManager.shared on
first use (start()/reevaluate()), after both singletons have finished
initializing. The injectable test initializer keeps its signature.

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

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

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

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

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

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 intermittent CI hang was caught by the new job timeout: the run
froze on the last remaining parallel test slot, an XCTest measure
benchmark (testNostrInboundEventHandling_freshEvents), after 4 hangs
in 5 runs - while the same suite completes in seconds locally and the
test itself is bounded. Independent of the micro-cause, benchmarks
do not belong inside the parallel suite: measuring while test processes
contend for cores is where our 2x CI variance came from. The parallel
run now skips benchmarks (BITCHAT_SKIP_PERF_BASELINES=1) and a
dedicated serial step runs them on an otherwise idle runner with a
6-minute step timeout, feeding the floor gate as before.

Two app-test jobs hung intermittently (40+ minutes against a normal
~4-5), holding macOS runners against GitHub's 360-minute default and
starving the queue - subsequent runs sat pending, which read as "CI now
takes 10+ minutes". Jobs now time out at 15 minutes (3x the normal
duration) so a hang fails loudly instead of silently consuming the
runner pool. The intermittent hang itself is under investigation
separately.

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.

During a panic reset, the new NoiseEncryptionService was assigned
before the identity barrier ran, so a previously queued send block
could observe the new crypto service alongside the old peer ID -
signing with the new identity while carrying the old sender. The
service teardown, replacement, callback configuration, and derived
identity swap now run inside one messageQueue barrier
(refreshPeerIdentity executes inline via its re-entrancy check), so
queued sends see either the complete old identity or the complete new
one, never a mix.

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.

The enqueue/drain/still-full logs fire per fragment during media
transfers (~150 lines for one 35KB image in field captures). They now
sample first + every 25th with a running event count, the sent/pending
lines merge into one, and the redundant peripheral-ready line is gone -
same treatment the relay event logs received. The drop-after-exhaustion
error stays unsampled.

Production builds previously still emitted info/warning/error entries
via os_log (content private-redacted, but entries, categories, and
timing metadata were visible, and message strings were constructed).
For a privacy-first app the right posture is silence: every SecureLogger
wrapper and both cores are now gated behind #if DEBUG, so release
builds construct no log strings and emit nothing. Debug builds are
unchanged (public formatting, level threshold via BITCHAT_LOG_LEVEL).

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

fileprivate). The previous store is renamed LegacyConversationStore

docs/CONVERSATION-STORE-DESIGN.md records the approved design: a
single-writer ConversationStore of per-conversation ObservableObjects
(per-conversation publishing, incremental ID index, folded caps, typed
change subject) replacing today's four-store/three-bridge topology,
with a five-step migration plan and explicit deletions/non-goals.
New pipeline benchmarks measure the CURRENT architecture end-to-end so
every migration step is judged against real before-numbers:
pipeline.privateIngest ~9.7k msg/s, pipeline.publicIngest ~6.8k msg/s
(200-message passes, stable within 1.5%).

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

* Guard subscription activation on connection identity
A REQ send completion from a dead socket could land after
handleDisconnection cleared the relay's subscriptions and re-mark the
subscription active, making the next connection skip the durable replay
and leave that relay silent. Only mark a subscription active if the
completing socket is still the relay's live connection.
Regression test defers send completions in the mock so the stale
completion deterministically interleaves between disconnect and
reconnect.

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).

ChatPeerListCoordinator, ChatComposerCoordinator, ChatOutgoingCoordinator,

ChatTransportEventCoordinator, ChatPeerIdentityCoordinator,
ChatMediaTransferCoordinator, ChatVerificationCoordinator, and

sentReadReceipts now route through owner intent ops

nostrKeyMapping, sentGeoDeliveryAcks/sentReadReceipts dedupe,

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.

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

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

NostrRelayManager no longer strands work when Tor is slow to bootstrap:
failed readiness waits retry (bounded by nostrTorReadyMaxWaitAttempts)
instead of dropping queued relay connections, parked EOSE callbacks fire
after exhaustion so callers never hang, and sends made before Tor is
ready are queued locally (capped) instead of being dropped on a failed
wait - still strictly fail-closed.
MessageRouter now prefers a connected transport over a merely
window-reachable one, and sends made on a weak reachability signal are
retained in the outbox until a delivery/read ack confirms receipt
(receivers dedup by message ID), with resends bounded by attempt count.
GCS sync filters from the wire are bounds-checked (p in 1...32, m > 1)
at both the packet decode and filter decode layers; oversized Golomb
parameters previously decoded to garbage via silent shift overflow.
BLELinkStateStore is now explicitly pinned to bleQueue: debug builds
trap any access from another queue, enforcing the ownership discipline
the surrounding code already relied on by convention.

Vendored arti.xcframework rebuilt from source (Rust 1.96.0, normalized
archive metadata for reproducible hashes). New ARTI-BINARY-PROVENANCE.md
records toolchain, rebuild steps, and a SHA256 manifest for every file
in the xcframework. A new CI workflow turns that policy into a gate:
PRs must keep the binary matching the manifest, and binary changes must
ship with source/lockfile/build-script evidence.
Also raises TorManager.awaitReady's default timeout from 25s to 75s to
match the bootstrap monitor deadline - a shorter wait reported "not
ready" while Arti was still legitimately bootstrapping, silently
stranding queued relay work.
Privacy policy, Tor integration doc, and privacy assessment updated to

* fix: Rate limit iOS peer notifications to prevent flood
- Remove aggressive formIntersection that cleared recentlySeenPeers
when peers temporarily dropped, causing them to be treated as "new"
- Add 5-minute cooldown between notifications (aligns with Android)
- Use fixed notification identifier so iOS updates existing notification
instead of creating new ones
- Only mark peers as seen when notification is sent, so peers arriving
during cooldown are included in the next notification
Fixes notification spam every 10-30 seconds when peers fluctuate.

* Improve BLE mesh reliability for large transfers
Major reliability improvements for fragment-based transfers (photos, files):
**Notification Queue Fixes**
- Fix silent packet loss when notification queue is full - now queues for retry
- Fix retry queue bug where remaining items were lost when one retry failed
- Add periodic drain mechanism as backup (every 5 seconds)
**Write Queue Fixes**
- Fix drainPendingWrites to use atomic take-send-requeue pattern
- Add logging when peripheral is ready for more writes
- Add periodic drain for pending writes as backup
**Fragment Pacing**
- Increase fragment spacing from 4-5ms to 25-30ms to prevent buffer overflow
- Conservative pacing prevents packet loss on congested BLE connections
**Thread Safety**
- Fix race conditions in stopServices() and emergencyDisconnectAll()
- Synchronize access to peripherals/centrals dictionaries during cleanup
- Clear pending message queues in emergencyDisconnectAll()
**Error Recovery**
- Add handlers for all BLE state transitions (poweredOff, unauthorized, etc.)
- Clear Noise session and re-initiate handshake on decryption failure
- Queue ACKs/receipts for delivery after handshake instead of dropping
- Re-queue failed pending messages for retry
**Other Improvements**
- Add route freshness validation in MeshTopologyTracker (60s threshold)
- Add TTL (24h) and size limits (100 per peer) for MessageRouter outbox
- Fix connection timeout to check peripheral.state before canceling
- Add NoiseEncryptionService.clearSession(for:) method

* Fix race condition and increase test timeouts
- Fix race in sendNoisePayload: use sync barrier instead of async
to ensure payload is queued before initiating handshake
(addresses Codex review feedback)
- Increase BLEServiceTests sleep from 0.5s to 1.0s for CI reliability

* Fix flaky test by using waitUntil instead of fixed sleep
Replace fixed 200ms sleep with waitUntil helper for more reliable
async assertion in routing tests. This prevents timing issues on CI.

Arti's dormant/wake FFI functions are no-op stubs that don't actually
implement dormant mode. The app was wasting 2.5-12 seconds trying to
wake from a dormant state that doesn't exist before falling back to
a full restart.
This change:
- Removes wakeFromDormant() call and function
- Simplifies goDormantOnBackground() to just mark state as not ready
- Goes straight to restartArti() on foreground, eliminating the delay

BitchatMessage is a class, so modifying its properties through an array
reference doesn't mutate the array itself. Changed var to let binding.

Update root Package.swift to reference localPackages/Arti instead of
the removed localPackages/Tor directory.

- Replace C Tor (0.4.8.21) with Rust Arti (1.9.0/arti-client 0.38)
- 70% smaller binary: 21MB xcframework vs 67MB (6.9MB vs 14MB per slice)
- Memory-safe Rust implementation with modern async (tokio)
- Same SOCKS5 proxy interface at 127.0.0.1:39050 for drop-in compatibility
- FFI wrapper (arti-bitchat crate) with C-compatible exports
- Swift TorManager maintains identical public API
- Aggressive size optimization: opt-level=z, lto=fat, panic=abort, strip
- Supports iOS device, iOS simulator (Apple Silicon), and macOS

Include the build-minimal.sh script alongside BITCHAT_TOR.md so future
rebuilds can be done directly from the bitchat repo.
