Part A — source-route origination policy:
- Gate route application (BLESourceRouteOriginationPolicy): only packets we
author, directed at a single peer, with TTL headroom, whose recipient is
not directly connected. Relays no longer attach routes to (and re-sign)
packets they merely forward.
- Version-gate paths: MeshTopologyTracker records the highest protocol
version observed per peer; BFS routes require every intermediate hop and
the recipient to be v2-observed, capped at 4 intermediate hops.
- Degrade on failure: BLESourceRouteFailureCache marks a routed send that
sees no inbound traffic from the recipient within 10s as failed and floods
for 60s before retrying routes.
Part B — REQUEST_SYNC fragmentIdFilter (TLV 0x06):
- Requester: BLEFragmentAssemblyBuffer reports stalled broadcast
reassemblies (no new fragment for 5s, retried at most every 10s); the
maintenance pass sends a types=fragment REQUEST_SYNC naming the stalled
8-byte fragment stream IDs to each connected peer.
- Responder: GossipSyncManager restricts the fragment diff to exactly the
named streams, bypassing the since-cursor while the GCS filter still
excludes pieces the requester holds; RSR/TTL-0/rate-limit semantics
unchanged and REQUEST_SYNC stays link-local.
- Bounds: at most 60 IDs per request (60*17-1 = 1019 bytes <= the 1024-byte
decoder cap); oversized 0x06 values are ignored, not fatal.
Docs: SOURCE_ROUTING.md gains the iOS origination policy (§8);
REQUEST_SYNC_MANAGER.md documents 0x05/0x06 as implemented.

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.

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%).

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
match the current implementation.
