-
-fix: make `cancelled` terminal on the servers, and bound a .NET turn on the client
-
-Two terminal states that were not terminal.
-
-**`cancelled` was advisory, not terminal (th-8628bf).** Cancellation is cooperative
-everywhere: `JoinHandle::abort()`, `context` cancellation and `CancellationToken` all
-take effect at the next yield point, not immediately. A turn that is executing rather
-than suspended keeps running — and an `await` on an already-completed future does not
-yield either — so work kept happening after the client had been sent the terminal
-`cancelled` (499).
-
-- **Python** was the worst: the Rich Interaction raise tool and the SEP extension host's
- `ui/confirm` park both caught `asyncio.CancelledError` alongside their own timeout and
- returned normally. asyncio only treats a task as cancelled if the `CancelledError`
- propagates out of it, so that *un-cancelled* the turn: it resumed, ran the next model
- call, persisted an assistant reply and emitted an `eventual_response` for a requestId
- the client had been told ended at 499. Both sites now re-raise; their own
- `TimeoutError` — a genuinely different thing — still degrades to "no answer".
-- **Rust** now drops post-cancel frames at the connection writer, the one point every
- frame passes through. Per-emit-site checks could not do this: frames leave a turn from
- the runner's stream loop, from inside a raise tool, from the write-confirmation gate
- and from the turn tail. The spawned turn also carries a cancelled flag, raised before
- the abort and before `cancelled` goes out, that its tail re-reads immediately before
- each side effect — including the OTP dispatch, which is not a frame and so cannot be
- covered by the writer gate.
-- **Go** gates the turn's sink once, for the same reason: a raise tool calls `sink()`
- straight from inside `Execute`, on the engine's goroutine, with no context check of its
- own. `offerOtp` also moved from the connection's context to the turn's, and re-checks
- immediately before dispatching — a host `OtpService` is under no obligation to honor
- the context, and this is a real code to a real person. The outbound persist re-checks
- too, because a store may ignore the context (the in-memory one takes it as `_`).
-
-**A .NET turn had no timeout (th-10ff63).** `SmoothAgentClientOptions` exposed only
-`RequestTimeout`, with no counterpart to TypeScript's `turnTimeout`, Go's
-`DefaultTurnTimeout` or Python's `turn_timeout`. A turn the server accepted but never
-terminated hung for the life of the process — no error, no diagnostic, and a leaked entry
-in the client's turn table. `TurnTimeout` now defaults to the same 120s and faults the
-turn with a `TurnTimeoutException`; `Timeout.InfiniteTimeSpan` disables it.
-
-The same file's `_ = _transport.SendAsync(...)` sat inside a try/catch that could never
-run: `SendAsync` is async, so a send failure faults the returned task instead of throwing
-at the call site, and the discarded task was never observed. The turn was therefore never
-aborted and leaked with no error. It is now awaited on a helper that aborts the turn.
