jackandClaude Opus 4.8 7251bc88fa Keep recording-error alerts from ending the open DM
Voice recording happens inside the people/DM sheet, but its error alert
was still presented unconditionally from the root view. A mic-permission
failure therefore force-dismissed the sheet and ended the conversation
through exactly the reconciliation path this branch fixes for the
Bluetooth alert.

Treat it the same way: the sheet-dismiss guard now also ignores
reconciliation while the voice alert is up, the root copy of the alert
defers to any other root modal (people sheet included), and the sheet
presents its own copy gated on the sheet's modal state. The voice alert
keeps priority over the Bluetooth alert on both levels via the existing
isVoiceAlertPresented flag, now mirrored into the people-sheet state.

jackandClaude Opus 4.8 ca669a4bc7 Surface refused media deletions in the affected chat
A refused delete/clear (journal write failure, reservation conflict,
path collision, capacity) only logged SecureLogger.error, so a wedged
/clear looked like success. Refusals now post a localized system
message (content.system.media_delete_refused, 30 locales) into the
affected private chat via the existing system-message mechanism, wired
at both the per-bubble delete and /clear refusal sites.

jackandClaude Opus 4.8 cc6e2bdad4 Actually delete legacy incoming media on explicit delete and /clear
Explicit deletion of LEGACY (non-stable-ID) incoming media left the
decrypted payload on disk indefinitely, waiting for 100MB oldest-first
quota cleanup. Restore real deletion safely with the machinery this PR
built: BLEIncomingFileStore.removeLegacyIncomingFile unlinks under the
payload-coordination lock only when the path is not pending delivery,
not held by a deletion reservation, and not owned by a stable receipt
or journal entry; otherwise the file keeps the leave-for-quota
fallback. The view model routes per-bubble deletes and /clear through
the gated unlink once no bubble in any conversation references the
basename.

jackandClaude Opus 4.8 867711506d Keep mirrored outgoing media when clearing another conversation
Clearing conversation A removed outgoing media IDs from every direct
conversation and unlinked the payload unconditionally, so a mirrored
outgoing bubble in conversation B (identity-alias handoff) lost both
its row and its file. Outgoing removal and file cleanup now mirror the
incoming alias protection: only IDs with no surviving copy in another
conversation are removed everywhere and unlinked.

A private-media policy resolution whose completion is dropped by

now removes the entry; retained records survive and the next reconnect

jackandClaude Opus 4.8 9df056d6a8 Reset BLEService's own receipt cache on panic completion
The panic media wipe runs on the file store PanicRecoveryOperations
.live() constructs, but receipt lookups are served by BLEService's own
incomingFileStore, whose in-memory index survived the wipe. Drop that
instance's cache in completePanicReset — after media deletion, before
radio admission reopens — so the next lookup rebuilds from the wiped
directory. The panic test now drives the production suspend/wipe/
complete sequence against the instance BLEService actually uses.

jackandClaude Opus 4.8 119c0bc8d8 Keep timeout-restore queues parked through the same-generation ready path
The deferral-buffer rework routes quarantine restores through a
same-generation ready transition that no longer rebuilds capability
state — but it drained both outbound queues unconditionally there,
bypassing the pending-convergence gate. Honor the restore reason in
that branch too: retrying deferred inbound ciphertext stays (it is
receive-side and safe under restored keys), while queue drains wait for
the convergence retry's establishment exactly as on the new-generation
path. Terminal restores keep draining immediately.

Also pre-drain the establishment's serialized forced announce in the
terminal-restore test so the tap only observes restore-driven traffic.

jackandClaude Opus 4.8 906165c676 Defer timeout-restore queue drains until Noise convergence completes
A responder timeout restores the quarantined old session generation and
requests one mandatory convergence retry, but both were dispatched
unordered onto the transport queue. When the restore handler won the
race it re-entered handleNoisePeerAuthenticated and drained the pending
private-message and typed-payload queues under the restored keys — keys
a legitimately restarted counterpart may have already discarded after
completing the replacement handshake whose message 3 was lost. Every
drained DM, read receipt, and invite then failed authentication
remotely and disappeared silently.

Restores now carry a reason. Terminal restores (claimed-identity
mismatch, or failures owning no convergence retry) drain immediately as
before: the counterpart never finished replacement keys, so the
restored generation is still valid on both ends. Pending-convergence
restores rebuild the generation-bound protocol state for receive
purposes but leave both outbound queues parked; the convergence retry
(or any later reconnect the revalidation policy initiates) re-enters
the authenticated transition with a fresh generation and drains them
under keys both sides hold. If the retry is cancelled the queues keep
waiting for the next establishment — the same contract every other
queued-before-handshake message already relies on — rather than
gambling them on keys only this side can prove.

jackandGitHub 2d96fd99a1 Encrypt private media before BLE fragmentation (#1434)
Closes the last cleartext private-content path over BLE: private DM images/voice were sent as plaintext signed fileTransfer packets, TTL-relayed across the mesh, so every relay saw the full bytes. Now the complete BitchatFilePacket is encrypted as a single Noise AEAD message (inner type 0x20, matching Android) and the opaque ciphertext is fragmented. Adds an authenticated in-session capability proof (0x21 TLV: capabilities + Ed25519 key), TOFU-style downgrade pinning, a per-send consent dialog for the signed-cleartext fallback to legacy peers, and a cancellation/admission registry so cancel/delete cannot race a deferred cleartext send.

Android wire constants (0x20 / 0x21 / capability bit 8) confirmed shipping. The 256-fragment preflight cap applies only to the directed fileTransfer migration fallback; encrypted media to capable peers uses the full receiver ceiling.

Rebased over #1428/#1349: identity reads go through BLELocalIdentityStateStore; the session-bound authenticated signing-key check and the announce-path TOFU pin are kept as complementary checks. Full local suite green (1744+197 tests).

jackandGitHub 10886428ca Deflake GeoRelayDirectoryTests under constrained runners (#1479)
Raises the file-local waitUntil default from 1s to 10s (returns early on success, so zero cost on healthy runs) and fixes a latent race in the observers test: it waited on the fetch-probe request count, which increments before handleFetchSuccess settles isFetching/lastFetchAt on the MainActor, so the next trigger notification posted into that gap was silently swallowed by the guard. Now waits on the .geoRelayDirectoryDidRefresh notification posted at the end of the synchronous success handler. Negative checks assert against captured baselines. No assertion weakened; 15/15 x 9 local runs including under 2x-ncpu CPU load.

jackandGitHub bcb21f2116 Require review before importing shared content (#1430)
Replaces the share-extension handoff that auto-sent shared text/URLs into the current channel with a validated, single-slot 24h envelope that shows the destination and a bounded preview and requires an explicit tap to copy into the composer — it never sends. Rejects malformed/oversized/control-character/non-HTTP(S)/expired payloads (including bidi-override U+202E), and clears on consume/cancel/expiry/panic.

Rebased onto main with Persian strings added for all new keys (30-locale coverage verified), plus a panic-recovery clear so an envelope staged during an interrupted wipe cannot survive relaunch.

jackandGitHub b96a41054e Pin announce signing keys to stop mesh identity spoofing (#1349)
TOFU-pins the Ed25519 signing key per noise key so a self-consistent announce that reuses a victim's peerID+noise key with the attacker's signing key/nickname is rejected instead of overwriting the registry and persisted identity. Complements #1432: that PR's signed-LEAVE verification reads the stored signing key this PR protects from announce-path poisoning.

Rebased onto main as a single commit; swift build --build-tests green, 40/40 targeted tests incl. the spoofing e2e cases, and #1432's suites 50/50 unaffected.

jackandGitHub d326cecb63 Fix BLE identity state races (#1428)
Converts BLEAnnounceThrottle to a lock-backed class and moves myPeerID/myPeerIDData/myNickname into a lock-backed BLELocalIdentityStateStore snapshot, so announces can never observe a split peer-ID/wire-ID during panic rotation. Serializes sendAnnounce onto the messageQueue barrier and moves the panic-reset pendingNoiseSessionQueues clear onto collectionsQueue (the queue every other mutation site uses).

Rebased onto main after #1431/#1432; integrates with #1431's panic-suspend structure (guard retained in both the outer sendAnnounce and the deferred worker).

jackandGitHub b59ad97dd6 perf: verify Nostr inbound signatures once, off the main actor (#1352)
Moves inbound Nostr Schnorr verification and NIP-17 gift-wrap decryption off the main actor into per-relay bounded AsyncStream pipelines (parallel across relays, ordered per relay), dedups before crypto, and removes the redundant second re-verify in NostrInboundPipeline/GeoPresenceTracker. Adds a panic-wipe generation counter so in-flight decrypts are discarded after a wipe.

Rebased onto main; #1451's 256 KiB pre-parse byte cap and tag limits are preserved and still enforced before any crypto/allocation.

Replaces the scheduled workflow that pushed upstream georelay CSV directly to main unreviewed with a validator-backed automation that resolves an immutable upstream commit, validates against the reviewed baseline, and opens a non-auto-merged PR (or tracking issue) instead of writing to main. Adds a mirrored strict client-side validator in GeoRelayDirectory (all-or-nothing, size/row/host/coord caps, streamed 512KiB cap, >=50% baseline overlap) that fails safe to last-known-good, and retargets runtime refresh to bitchat's reviewed copy.

Persian was the one notable gap in the 29-language catalog. Translate all

Settings gains a LANGUAGE section: a picker over every language the bundle
ships (native names via Locale), backed by an AppleLanguages override so
users can run bitchat in a language different from the device's. Localization
resolves at process start, so the picker surfaces a restart note.

* fix: skip admin fallback when country exists but is duplicate

Prevents mixed labels like "United Kingdom and Scotland" for
single-country geohashes. Admin fallback now only triggers when
no country is available from the placemark.

* fix: migrate stale low-precision bookmark names so country-first logic applies

Users who bookmarked a <=2-char geohash before the country-first resolver
kept the old administrativeArea cache (e.g. "England" for `gc`) because
resolveBookmarkNameIfNeeded bails when bookmarkNames[gh] is non-nil. Add a
one-shot, versioned migration that drops cached names for <=2-char geohashes
on load; the next LocationChannelsSheet .onAppear re-resolves them via the
fixed logic. Higher-precision entries are untouched.

b205a55523 Consolidate duplicate BLE links after restore; duplicate fragment-stream suppression; onChange coalescing (#1426)
* Consolidate duplicate BLE links after restore; suppress duplicate fragment streams; onChange coalescing

Field evidence (two-phone test after BLE state-restoration relaunches):
both phones held 2-3 simultaneous same-role connections to each other —
one side received every packet from three distinct centrals all bound to
the same peer — so every PTT voice frame arrived 3x, and a 41KB voice
file went out as TWO complete independent 89-fragment streams (different
assembly ids), both fully reassembled and the duplicate only dropped at
the very end by messageID dedup. 2-3x airtime/battery on all traffic
plus doubled reassembly memory.

Root causes and fixes:

- Duplicate links stayed unbound forever: announces (the only packet
  that binds a link to a peer) went through the per-peer duplicate-link
  collapse, so a peer's second/third link never received the announce it
  needed to become bound — and unbound links pass the collapse untouched,
  so every broadcast sprayed down all of them. Direct announces now
  bypass the collapse and reach every live link (relayed announces keep
  it); once bound, the existing collapse dedups all traffic.

- Same-role link retirement: a verified direct announce now consolidates
  our central-role connections to that peer — keep the link the announce
  arrived on (or the most recently bound one), cancel other connected
  links bound to the same peer. One connection per role per peer is the
  normal dual-role topology; only same-role duplicates are touched, only
  links already announce-bound are retired (never pre-announce links),
  at most one retirement per peer per rebind-cooldown window, and the
  peer keeps a live link either way. Directness stays forgeable (TTL is
  unsigned), so a replay could nominate the survivor — bounded by the
  cooldown and by DM routing's existing canDeliverSecurely gate. A
  rotation rebind now also cancels other stale links still bound to the
  rotated-away ID, so the ghost identity retires promptly.

- Deterministic preferred-link collapse: when several bound links to one
  peer are candidates, collapse now keeps the peer's most recently bound
  link (the reverse-mapped one) instead of dictionary order; links
  without a discovered characteristic are excluded from fanout (they
  cannot be written to, and could silently eat a peer's collapsed copy).
  links(to:) now reports all bound peripheral links, and removing one
  duplicate no longer clobbers the reverse map of the survivor.

- Duplicate fragment streams: a transferId-less resend (gossip-sync
  replay, spool) of file content already being fragmented out to a
  covering audience is dropped at the outbound scheduler (broadcast
  covers everyone; directed covers its recipient). App-initiated sends
  carry an explicit transferId the progress UI tracks and always run.
  A peer that asks after the stream completes still gets a resend.

- didUnsubscribeFrom no longer flaps a peer that is still live on other
  links (the far side retiring its duplicate arrives as an unsubscribe);
  didDisconnectPeripheral bookkeeping is skipped for self-retired links
  by removing the store entry before cancelling.

Also: guard the DeliveryStatus onChange state write in TextMessageView/
MediaMessageView (unconditional per-row writes under a message storm
tripped SwiftUI's "tried to update multiple times per frame" warning).

The restore-path bgRemaining=∞ log was already fixed on main (#1425
review follow-up 07b5ac31: init-time seed + sampler-routed restore
captures); verified, no change needed.

* Review fixes: multi-link disconnect guard, characteristic-aware retirement

Adversarial review of the duplicate-link PR (merge-with-nits):

- didDisconnectPeripheral gets the same multi-link guard as the
  unsubscribe path: when a duplicate link drops naturally while the peer
  stays live on another (dual-role central link, or a second bound link
  during the post-restore consolidation window), peer-disconnect
  bookkeeping (markDisconnected + disconnect notify) no longer runs — a
  UI blip until the next announce re-marked the peer connected. The
  reverse map was just repaired onto a connected survivor, so
  directLinkState is the accurate probe. Scan restart and connect-slot
  refill stay unguarded: they respond to the physical drop regardless of
  remaining logical links. (No unit test: driving the CBCentralManager
  delegate requires CBPeripheral instances, which cannot be constructed
  in tests; the policy pieces backing the guard are covered.)

- Retirement is now characteristic-aware: the policy snapshot carries
  characteristic presence, and keptPeripheralUUID selects anchors only
  among writable links while any exist — consolidation must not keep a
  link mid-service-rediscovery (didModifyServices cleared its
  characteristic) and cancel the writable duplicate, stranding outbound
  traffic on the central link until rediscovery finishes. When neither
  anchor is writable but a writable duplicate exists, consolidation
  defers to a later announce instead of guessing. The reverse-map
  survivor repair in removePeripheral prefers writable links for the
  same reason. Three new policy tests cover charless-vs-writable.

Deferred with code comments per review: central-side collapse keeps the
oldest subscription (no recency signal; remote consolidates within its
cooldown), and the extra preferred-bindings bleQueue hop in
sendOnAllLinks (fold into a combined snapshot if profiling flags it).

* Fix restore-path main↔bleQueue deadlock and courier drop amplification

A device froze permanently in a two-phone test. Debugger stacks showed an
ABBA deadlock: the main actor was in bleQueue.sync (delivery-ack send →
broadcastPacket → readLinkState) while bleQueue was in main.sync
(captureBluetoothStatus reading backgroundTimeRemaining). The load that
lined the two edges up came from a courier-drop amplification storm:
drop dedup was in-memory only while the outbox driving 120s re-deposits
is persisted, so every relaunch republished the same undelivered DM as a
fresh 24h relay drop and every gateway relaunch re-fetched the whole
backlog — ~20 copies of one DM delivered in 40ms, each triggering
decrypt + delivery + ack + handshake work.

Fixes, in rank order:
- Edge B (P0): captureBluetoothStatus no longer main.syncs from bleQueue;
  backgroundTimeRemaining is sampled on main and cached behind a lock.
  Invariant documented: bleQueue must NEVER sync-dispatch to main.
- Edge A (P0, defense in depth): sendDeliveryAck / sendReadReceipt /
  sendPrivateMessage / sendNoisePayload / triggerHandshake hop to
  messageQueue like sendMessage, so no main-actor call path reaches
  readLinkState's bleQueue.sync.
- Drop dedup (P1): publishedDropKeys and seenDropEventIDs persist across
  relaunches (new BridgeDropDedupStore, entries expire with the 24h
  NIP-40 drop window; wiped on panic) — one drop per message ID per 24h
  regardless of relaunch count.
- Receiver dedup (P1): openCourierEnvelope dedups on the inner private
  message ID before delivery, so a duplicate copy costs one decrypt and
  never re-delivers, re-acks, or re-triggers a handshake.
- Handshake gating (P2): queued acks initiate a Noise handshake only for
  reachable peers; mail from absent/rotated identities no longer turns
  each copy into a mesh-wide handshake flood (the ack stays queued and
  flushes when a session eventually establishes).
- Outbox (P3): re-enqueueing a queued message ID carries over its
  depositedCourierKeys so resends stop re-burning the same courier slots.

* Review fixes: offline-drop durability, gateway handoff retry, restore-log freshness, coalesced persist

Adversarial review of the storm/deadlock PR surfaced four issues:

- Offline blackhole (must-fix): a deposit made while relays were down
  persisted its dedup key even though the drop only sat in the in-memory
  pending queue — app killed before reconnect meant the relaunch lost the
  drop but the persisted key blocked every re-deposit for 24h. The
  persisted snapshot now excludes keys still pending; they become durable
  only when flushPendingDrops actually publishes them.
- Gateway handoff: seen-event IDs were consumed before the deliverToPeer
  handoff; a failed handoff (peer walked away) permanently dropped the
  event for a single-gateway island. deliverToPeer now reports whether
  the handoff was attempted, and a failure releases the seen slot so a
  relaunch or backlog redelivery retries.
- Restore-path logs: central/peripheral-restore captures logged the init
  sentinel bgRemaining=∞. The cache is now seeded in init's main-thread
  branch and restore captures route through the sampler, which refreshes
  the cached budget before logging.
- Persist cost: the dedup record was a full JSON encode + atomic write on
  the main actor per mutation (once per event during a backlog re-fetch).
  Writes now coalesce behind a 1s window, flushed immediately on
  background/terminate; panic wipe stays immediate.

* Remove BoundedIDSet.remove, orphaned by the ExpiringIDSet migration

The drop-dedup sets that needed slot release moved to ExpiringIDSet;
remaining BoundedIDSet users only insert and check. Periphery caught it.

304460ee83 Nearby notes: tap-to-reveal (consent-gate the location subscription) + subscription hygiene (#1422)
* Nearby notes: tap-to-reveal before any relay REQ, plus shared subscription pool

The nearby-notes counter used to open a live building-precision (precision-8)
geohash REQ to the closest geo relays whenever the mesh public timeline was
visible — a passive location side-channel with no opt-in. Now nothing
subscribes until one explicit act reveals the counter for the session: tapping
the new "check for notes left here" line on the empty mesh timeline (static,
no network), opening the notices sheet's geo tab, or a successful /drop. The
app-info setting stays the default-ON kill switch and still gates /drop.

Subscription hygiene alongside:
- LocationNotesManager.deinit now unsubscribes its live REQ (hopping to the
  main actor like the timer teardown) instead of only invalidating timers.
- New refcounted LocationNotesPool dedupes the counter's and the notices
  sheet's identical 9-cell kind-1 REQs into one shared manager per geohash;
  both callers release-and-reacquire instead of retargeting in place, and the
  sheet releases its ref on dismissal.

The reveal affordance is localized across all 29 catalog locales, and new
NearbyNotesCounterTests cover the no-REQ-before-reveal contract, the 9-cell
filter, NIP-40 expiry handling, single unsubscribe on deactivate, and pool
refcounting.

* Review fixes: permission-gate the hint, exclude building cell from pre-reveal sampling, explicit-act reveal only

Fixes the verified review findings on the tap-to-reveal PR:

- Permission dead-end: the "check for notes left here" hint now renders
  only when location permission is already authorized (it never prompts).
  Previously a location-denied install could tap it, flip the sticky
  revealed flag, and get nothing for the rest of the session because
  retarget() guards on authorization. Predicate lives on
  NearbyNotesCounter.offersRevealHint(permissionState:) and is reactive
  to the published permission state.

- Building-cell sampling: background geohash sampling subscribed
  geo-sample-<gh> for every regional level including the precision-8
  building cell, pre-reveal — contradicting the claim that nothing
  building-precision hits a relay before the explicit act.
  GeoChannelCoordinator now excludes the building level until
  NearbyNotesCounter.revealed (injectable publisher for tests); coarser
  levels keep the nearby-conversation hint and participant counts
  working, and bookmarks stay exempt (bookmarking is explicit).

- Implicit reveal: opening the notices sheet no longer reveals — the
  sheet auto-lands on the geo tab whenever a location channel is
  selected, so browsing a remote geohash and opening notices revealed
  the LOCAL building subscription. reveal() now fires only on the
  person actively picking the geo segment, and only when the sheet has
  a geo scope (the empty-mesh hint tap and /drop stay as before).

- Subscription hygiene: switching the sheet geo → mesh releases the
  pooled notes manager (the REQ was left streaming behind the mesh
  board); switching back re-acquires from the pool. The dismissal
  release stays balanced — liveGeoManager is nil after the tab-switch
  release.

- VoiceOver: the hint button exposes the plain localized action text
  instead of the decorated "* 📍 … *" label.

- Removed LocationNotesManager.setGeohash: zero callers, and calling it
  on a pooled instance would corrupt the pool's keying and refcounts.

New tests: hint permission gate, explicit-geo-tab reveal contract,
building-cell sampling exclusion before/after reveal, pool
release/re-acquire round trip. Full suite (1467) green; iOS simulator
build green.

* Deflake peer-snapshot binding waits: longTimeout for the multi-hop pipeline

CI failed once on initialization_bindsPeerSnapshotsIntoAllPeers: the
snapshot -> allPeers binding crosses the mock transport's unstructured
Task, UnifiedPeerService.updatePeers, a receive(on: main), and another
Task { @MainActor } in bindPeerService — all contending with every
parallel worker. On the failing runner the whole suite took 10.1s
(usually ~4.4s locally), so the positive 5s defaultTimeout wait lost
the race. That's exactly the case TestConstants.longTimeout documents;
passing runs return as soon as the condition holds and never pay it.

Not caused by the tap-to-reveal changes: nothing on that pipeline was
touched, and 20 full parallel-suite loops each on the branch and on
origin/main reproduce zero failures locally. The two sibling waits on
the same pipeline in this file get the same timeout.

b7c6f42b3a Close forged-directness link-rebind DoS on DM routing (#1421)
* Gate connected-link trust on a secure session; deny forged direct announces the connected shortcut

Residual gap after the rotation-heal containment (#1401): "verified
direct" announces prove the signature but not directness — TTL is
unsigned — so a malicious connected peer can replay a victim's fresh
announce with its TTL restored. When the victim has no live link, the
replayer's link rebinds to the victim's ID and reads as "connected",
and MessageRouter's connected fast-path then trusts it outright: every
DM stalls on a Noise handshake the replayer can never complete and is
silently lost while showing "sent".

Router-level trust gate (no wire change):
- Transport gains canDeliverSecurely(to:) — BLE answers with an
  established Noise session; Nostr keeps its prompt-delivery predicate;
  the protocol default forwards to canDeliverPromptly for transports
  without a forgeable link layer.
- MessageRouter.sendPrivate only trusts a connected link outright when
  it can deliver securely; otherwise it still sends (kicking the
  handshake on a genuine link) but retains a copy and hands a sealed
  copy to couriers, like the reachable path. flushOutbox gets the same
  gate so a flush over an insecure link resends instead of dropping the
  retained copy.

Presence hardening (defense in depth): a "direct" announce arriving on
a link already bound to a different peer no longer shortcuts the
claimed peer into "connected" — only real link state does. Genuine
first-contact and direct announces are unaffected; only the ambiguous
heal path loses the forgeable shortcut.

* Harden the insecure-link outbox bound; document the second-replay presence gap and the courier metadata tradeoff

Review follow-ups on the canDeliverSecurely gate:

- flushOutbox no longer counts connected-but-insecure flushes toward the
  maxSendAttempts drop: the message was actually transmitted over a live
  link, so a peer whose Noise handshake stalls across reconnect flapping
  must not burn through the cap and lose the store-and-forward copy the
  gate exists to preserve. Retention stays bounded by the 24h outbox TTL
  and the per-peer FIFO cap; acks still clear it. Attempt-counting stays
  for reachable-only (heuristic) sends. Regression test: >8 connected-
  insecure flushes keep the retained copy, drop callback never fires.

- Document the known second-replay presence gap: linkBoundToOtherPeer
  reads the binding before rebindLinkAfterVerifiedDirectAnnounce steals
  the link, so once a first replay has rebound a link to an absent
  victim's ID, a second replay marks the victim connected. Presence
  display only — DMs stay on the retain+courier path via the router
  gate. Not closed at the announce layer because the post-rebind state
  is indistinguishable from a legitimate rotation/reconnect heal (a
  supported, field-verified flow). Covered by a two-announce test.

- Note the accepted courier-spray metadata tradeoff at the connected-
  insecure send: nearby verified peers receive a sealed copy (they learn
  a DM exists, never its content), cleared on ack.

* Promote a healed rotation to connected; normalize the secure-delivery probe; retain Codable properties in Periphery

Codex review follow-ups on 5017c232:

- P1: a legitimate rotation announce necessarily arrives on a link still
  bound to the OLD peer ID, so the linkBoundToOtherPeer denial stored the
  new identity as disconnected — and the rebind only fixed link state,
  never the registry. A healed rotation then read as disconnected until
  the peer happened to announce again. rebindLinkAfterVerifiedDirect-
  Announce now promotes the rebound identity to connected after the
  containment checks pass (registry markConnected + topology/snapshot/
  peer-list refresh; the .peerConnected UI event already fired from the
  announce path). This consciously moves the forged-presence residue
  from second-replay to first-successful-rebind — bounded by the rebind
  containment (never steals a live identity, one rebind per link per
  cooldown) and still display-only: DMs stay gated on canDeliverSecurely.
  Comments and the pinned tests updated; new regression test covers
  rotate-on-open-link -> rebind -> isPeerConnected(new) == true.

- P2: BLEService.canDeliverSecurely probed the Noise session with the
  peer ID as given, but sessions are keyed by the short wire ID — a send
  keyed by the full 64-hex Noise key (favorites resolution) misread an
  established session as insecure and needlessly retained + couriered
  every DM until ack. Normalize with toShort() like isPeerConnected.
  Test drives a real XX handshake and asserts both ID forms pass.

- Periphery: the PrekeyBundleStore.StoredBundle.noiseKey "assign-only"
  flake fired again and slipped past its baselined USR (read exists in
  loadFromDisk; the indexer intermittently misses it). Replace the
  baseline entry with retain_codable_properties: true — deterministic,
  and a truly-dead Codable field is a persisted-format change anyway.
  Local periphery scan --strict: no unused code detected.
