jackandClaude Fable 5 10ba71b1f8 Fix panic-wipe window, frame byte bound, and delivery-side test waits
Three confirmed defects from adversarial review of the per-relay inbound
pipeline (PR #1352):

- MEDIUM-2: a detached gift-wrap decrypt spawned just before a panic wipe
  strongly captures the pre-wipe Nostr private key and could deliver
  plaintext into ChatViewModel after the wipe. Add a per-pipeline
  monotonic wipe generation (NostrInboundPipeline.wipeGeneration), bumped
  from panicClearAllData via invalidateInFlightDecrypts(); spawn sites
  capture it and every main-actor hop drops the task's result on
  mismatch. The account-mailbox path (processNostrMessage) had the same
  pre-existing hazard and gets the identical guard, capturing the
  generation atomically with the identity fetch.

- MEDIUM-1: the per-relay stream cap bounds FRAMES (256) but not BYTES;
  with the URLSession default of 1 MiB per WebSocket frame a hostile
  relay could pile up ~256 MiB. Set URLSessionWebSocketTask
  .maximumMessageSize to TransportConfig.nostrInboundMaxFrameBytes
  (512 KiB — an order of magnitude above any legitimate Nostr event or
  gift wrap we produce or expect), halving the worst case to 128 MiB,
  and correct the "cannot exhaust memory" comments to state the actual
  cap × maxFrameBytes bound.

- LOW-5: three NostrRelayManagerTests gated on messagesReceived (first
  main hop) then immediately asserted delivery-side state that only
  lands after off-main verification plus a second main hop. Wait on the
  delivery-side state (receivedIDs / duplicate-drop counts) directly,
  keeping all assertions.

Also: brief comment documenting pendingGiftWrapIDs growth (LOW-6) and a
regression test that a panic wipe issued after spawn drops the decrypted
result while leaving the pipeline usable.

jackandClaude Fable 5 2d5250e49a Verify Nostr inbound per relay to avoid head-of-line blocking
The single global inbound consumer serialized ALL relay traffic behind
one Schnorr-verification queue, so a burst of EVENT frames from one
busy/malicious relay stalled DMs, OKs, EOSEs, and events from every other
relay (codex P2). Give each relay connection its own bounded AsyncStream +
detached serial consumer instead: N relays verify in parallel while each
relay's frames stay in arrival order (per-relay ordering preserves the
per-subscription ordering that actually matters, since a subscription's
events for a relay all arrive on that relay's socket).

Continuations live in a lock-guarded Sendable router so the non-isolated
socket receive callback can route a frame to the right relay stream with
no per-frame main hop; the main actor owns pipeline start/teardown, wired
into connect, disconnect, panic wipe, per-relay disconnect, retry, and the
default-relay revoke path. Streams use .bufferingNewest so a relay flooding
faster than it verifies sheds its OWN oldest frames — it can neither exhaust
memory nor starve other relays.

Security invariants are unchanged: signature verified exactly once, off
main; dedup pre-check-before / record-after-verify (forged copies still
can't poison the dedup set); the atomic main-actor check-and-record in
deliverVerifiedInboundEvent; the inner NIP-17 seal check untouched.

Tests: existing per-relay in-order-delivery and tampered-signature
dedup-poison tests still pass; add a cross-relay non-blocking test proving
a large backlog on relay A does not delay a later frame on relay B.

68eeba97ff Use Xcode-bundled Swift in CI instead of a standalone toolchain (#1353)
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.

jackandClaude Fable 5 8af6fc2d5f Verify Nostr inbound signatures once, off the main actor
Every inbound relay event was Schnorr-verified TWICE, both times on the
main actor: once in NostrRelayManager.handleParsedMessage and again in
each NostrInboundPipeline / GeoPresenceTracker handler. Each
verification re-serializes the event JSON, hashes it, and runs a
secp256k1 Schnorr verify, so busy geohashes paid double crypto on the
UI thread. Geohash gift-wrap NIP-17 decryption (two ECDH+ChaCha layers)
also ran on the main actor.

Changes:
- NostrRelayManager now owns a serial off-main inbound pipeline
  (AsyncStream + single consumer task): frames are parsed and verified
  in arrival order off the main actor, preserving per-subscription
  delivery order. This is the single verification point for the whole
  inbound path; downstream handlers only ever see verified events.
- Dedup stays two-phase and unpoisonable: a cheap main-actor duplicate
  LOOKUP runs before verification (duplicate fan-in from several relays
  never pays for crypto — previously every duplicate was verified), and
  events are RECORDED as seen only after the signature verifies, so a
  forged-signature copy can never suppress the genuine event.
- NostrInboundPipeline and GeoPresenceTracker drop their redundant
  re-verification; geohash gift-wrap decryption moves off the main
  actor following the existing account-mailbox Task.detached pattern
  (atomic main-actor check-and-record, then decrypt off-main, then hop
  back for state updates).
- Tests: relay-level coverage for tampered gift wraps and for in-order
  delivery of back-to-back frames; pipeline-level tampered-signature
  tests move to the relay boundary where the invariant now lives; the
  mock relay connection queues frames emitted before receive re-arms.

jackandClaude Fable 5 f07b032b99 Fix CI exit hang: sign reassembled public packets in FragmentationTests
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).

jackandClaude Fable 5 2cbcb290f7 Remove lingering save timer from SecureIdentityStateManager (CI exit hang)
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.

jackandClaude Fable 5 9cf7c80518 Reduce test-process churn to fix flaky CI exit hang
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).

jackandClaude Fable 5 f76fd8a538 Fix CI hang: gate maintenance timer to Bluetooth-enabled; sign dedup test packet
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.

jackandClaude Fable 5 09c2c12838 Fix deadlock in identity-cache forceSave (CI hang)
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.

jackandClaude Fable 5 8378ff949a Address Codex review: verify public messages against registry signing key
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).

jackandClaude Fable 5 ca63893197 Fix security audit findings: 3 critical, 7 high
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).

fdf28aa5bb Fix launch crash: recursive dispatch_once between NostrRelayManager and NetworkActivationService (#1343)
* 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.

266827ceff Extend BLE mesh range: relax RSSI gates, lift sparse TTL clamps, faster walk-back reconnects (#1338)
* 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.

* 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).

97bc3f53bc Raise positive waitUntil timeouts to 5s for loaded CI runners (#1340)
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.

9dc0ba6991 Fix CI app-suite deadlock: cooperative-pool-blocking thread-safety tests (#1339)
* 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

jackandClaude Fable 5 fa136d8973 Run perf benchmarks serially in their own CI step
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.

jackandClaude Fable 5 7fbe6a4a7e Fail hung CI jobs fast with a 15-minute timeout
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.

jackandClaude Fable 5 4791114406 Recalibrate perf floors to slowest-observed-CI basis
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.

jackandClaude Fable 5 1a6a08f92a Make Noise-service replacement atomic with the identity swap
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.

jackandClaude Fable 5 0b007eee1a Close the final re-grade findings: parked EOSE fallback, panic atomicity, overflow visibility
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.

jackandClaude Fable 5 0e38ccfb3b Snapshot delivery status in message rows so read receipts render immediately
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.

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.

jackandClaude Fable 5 22be3d6392 Resurrect dead Noise vector tests; add CI perf floors; make tests hermetic
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.

jackandClaude Fable 5 8a867a17a1 Remove noise service exposure; single-owner selection state
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.

jackandClaude Fable 5 8289a6d05e Republish mirrored conversations on shared-instance status changes
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.

jackandClaude Fable 5 38331e62f1 Cut views over to ConversationStore; delete legacy store, bridge, resolver
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)

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.

jackandClaude Fable 5 99d1d1dccd Cut public message path over to ConversationStore; delete PublicTimelineStore
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.

jackandClaude Fable 5 879d8cba12 Cut private message path over to ConversationStore
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%).

75dd83d9cc Make location notes robust: durable relay subscriptions, failure decay, auto-recovery (#1333)
* 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.

Addresses Codex review on #1333.

Also root-causes the long-flaky gift-wrap dedup test: parallel tests

dedup record mid-test. The invariant (forged-signature copies never
poison dedup) now lives as a deterministic NostrInboundPipeline
