   REDO-discarded turns.
+- **switchyard-server container image** — a root `Dockerfile` builds the

+  (#421)
+- **Run-span task metadata** — `task_kind` and `agent_role` are recorded on
+  the run span, so routing telemetry can be segmented by the semantic class of
+  work; span fields only, no new metric labels. (#249)
+- **Unified LLM-classifier bindings** — LLM-classifier routing is available
+  through the native PyO3 bindings, unifying the Python-side surface. (#465)
+
+### Changed
+
+- **`Algorithm::route` returns `Result<RoutingOutcome>`** — instead of the
+  bare final `Result`, so callers observe the full routing outcome (see #458

+### Fixed
+
+- **Reasoning order in mixed stream chunks** — the OpenAI Chat stream decoder
+  emits reasoning deltas before content deltas from the same chunk, so
+  interleaved reasoning is no longer reordered. (#387)
+- **Anthropic structured output in requests** — a schema arriving on
+  `/v1/messages` now reaches the neutral request and the forwarded upstream
+  body; unmappable output formats produce diagnostics instead of silent drops.
+  (#462)
+- **Responses tool arguments emitted once** — `output_item.done` repeats the
+  complete function-call arguments the delta events already carried; the
+  decoder suppresses the repeat when they match. (#469)
+- **Content filter stops as Anthropic refusal** — `StopReason::ContentFilter`
+  maps to Anthropic's `refusal` stop reason (and back) instead of `end_turn`,
+  so moderation stops remain distinguishable. (#370)
+- **JSON rejection statuses preserved** — request-body rejections keep the
+  underlying status code instead of always returning 400. (#406)
+- **Launcher config errors without tracebacks** — `switchyard launch` reports
+  configuration errors as messages rather than Python tracebacks. (#475)
+- **Default log level** — logging defaults to `info` for all crates instead of
+  discarding logs from crates without an explicit level; an unnecessary `rand`
+  callback was removed on the way. (#471)
