The client, not the app, now drives the transport; events are delivered
asynchronously, per ADR 0001.
- ChatClient owns Arc<Mutex<Core>> + a worker thread.
- The worker select!s over the inbound and shutdown channels; Drop joins it.
Outbound runs on the caller's thread.
- A single Transport (DeliveryService + inbound()) owns both directions of the
boundary, so the client takes one transport rather than a (delivery, inbound)
pair. InProcessDelivery::new, CDelivery, and chat-cli's transports implement it.
- FFI replaces client_receive with client_push_inbound + client_poll_events.
- chat-cli drains Receiver<Event>; inbound and event channels are both crossbeam.
- Corrects ADR 0001's inbound sequence to push — the worker parks on select!,
it never polls.
Make the conversations core Send so the threaded client can own it behind an
Arc<Mutex<Core>>: a background worker polls the transport and handles inbound
payloads while the application thread issues outbound calls (send, create
conversation). Sharing the core across those two threads means moving it into
the spawned worker, which is only legal if it is Send. Access stays serialized
by the client's Mutex (one thread at a time), so the core needs Send but not
Sync and carries no lock of its own. See
docs/adr/0001-client-event-system.md for the background-poller design.
The Rc<RefCell> service-sharing is what made the core !Send. Context is de-Rc'd
and renamed to Core, owning its services outright and driving the inbox and
conversation primitives with plain &mut self.
- Services (identity, delivery, store, registry, MLS context, causal history)
are bundled into a ServiceContext<S> behind an ExternalServices trait, with
S = (DS, RS, CS). Constructors live on the (DS, RS, CS) form because S cannot
be inferred backwards through S::DS.
- Inbox, InboxV2, PrivateV1Convo, and GroupV1Convo become non-generic and
receive the ServiceContext bundle as a &mut/& parameter; no Rc or
RefCell-as-shared-state remains, so Core is Send whenever its injected
services are.
- Dispatch branches on ConversationKind in one place: Core rebuilds the target
as a Convo<S>/GroupConvo<S> trait object bound to the service bundle, so
conversations never escape the orchestrator.
- CausalHistoryStore drops its Rc, keeping a plain RefCell.

* chore(flake): accept extra system attr; add perl for openssl-sys build
forAllSystems calls the lambda with {system, pkgs}; strict
destructuring requires `..` to ignore the system attribute.
`pkgs.perl` is needed because openssl-sys is pulled vendored via
libsqlite3-sys / rusqlite / chat-sqlite, and its `perl Configure`
step needs FindBin.pm, which Fedora's system perl doesn't ship.
* feat: introduce client event system
- Core processing yields a `PayloadOutcome` enum — `Empty`, `Convo`, or
`Inbox`. `ConvoOutcome` carries a conversation id and an optional
decrypted `Content`; `InboxOutcome` adds a `NewConversation`
(id + `ConversationClass`) for a peer-initiated conversation.
- Client translates `PayloadOutcome` into app-facing `Vec<Event>`
(`ConversationStarted`, `MessageReceived`) at the boundary, so the
application loop sees discrete events rather than core types.
- MLS group welcomes produce a `ConversationStarted` event with no
initial content, fixing the silent-group-join case where the inbox
layer dropped the observation.
- C FFI exposes an `EventList` opaque type with indexed accessors and
an `Invalid` sentinel for out-of-bounds / non-applicable reads.
- Symmetric `Inbox` / `InboxV2` handlers: both return
`Result<InboxOutcome, _>` and own the persistence + ephemeral-key
cleanup for the conversations they create.
- Updated and simplified `docs/adr/0001-client-event-system.md`.
* chore(flake): bump nixpkgs to nixos-unstable-small
Temporary. The two crates.io UA fixes (NixOS/nixpkgs#512735 for
fetchCargoVendor's python-requests UA, NixOS/nixpkgs#524985 for
importCargoLock's curl UA) haven't propagated to nixos-unstable yet.
Switch to nixos-unstable-small and force logos-delivery to follow so
the smoketest gets the same fix. Revert once nixos-unstable catches up.

Implement a `client` crate that wraps the `libchat` context behind a
simple `ChatClient<D>` API. The delivery strategy is pluggable via a
`DeliveryService` trait, with two implementations provided:
- `InProcessDelivery` — shared `MessageBus` for single-process tests
- `CDelivery` — C function-pointer callback for the FFI layer
Add a `client-ffi` crate that exposes the client as a C API via
`safer-ffi`. A `generate-headers` binary produces the companion C
header.
Include two runnable examples:
- `examples/in-process` — Alice/Bob exchange using in-process delivery
- `examples/c-ffi` — same exchange written entirely in C; smoketested
under valgrind (to catch memory leaks) in CI
iterates: #71
