Iterator content silently lost on request retry

Medium Severity

When content is an Iterable[bytes] (like a generator), the iterator is consumed on the first request attempt. If a retryable error occurs, the retry logic uses model_copy which performs a shallow copy, so options.content still references the same exhausted iterator. Subsequent retry attempts send an empty request body. This is exacerbated by DEFAULT_MAX_RETRIES being increased from 0 to 2 in this same PR. Users passing generator-based content could experience silent data loss on transient failures.

PR Summary

Medium Risk
Touches core request/serialization and runner tool-execution paths (new retry defaults, raw content support, dependency-aware scheduling, and MCP credential embedding), which can change runtime behavior across most API calls. CI/test harness changes (removing Prism mock) may reduce coverage for request-shape regressions.

Overview
Releases v0.3.0 with new API surface and behavior changes.

Adds new client resources for POST /v1/ocr (client.ocr.process) and POST /v1/responses (client.responses.create), updates audio speech typing to support custom voices/new TTS model, and sets a default as_base_url plus an optional X-Provider-Model header.

Updates the HTTP client to support raw/streaming binary request bodies via a new content parameter (sync/async) with validation + deprecation of body=bytes, and switches JSON body serialization to a custom encoder (openapi_dumps) to handle types like datetime and pydantic.BaseModel.

Refactors DedalusRunner to accept/forward a broader set of chat-completions kwargs, preserves thought_signature during streamed tool-call accumulation, and introduces a dependency-aware local tool scheduler (_scheduler.py) that can run independent tools concurrently. MCP credential embedding now attaches only per-server credentials (via slug_to_connection_name) and MCP server wire serialization restores Pydantic v1 compatibility.

Operational updates: default retries increased to 2 with longer backoff, CI actions/uv versions bumped (and PyPI publish job set to production environment), docs updated (MCP install URLs and retry defaults), formatting now targets all api.md files, and Prism mock-server scripts/test setup removed.

Missing assistant message before tool execution in streaming paths

High Severity

Both streaming paths (_execute_streaming_async and _execute_streaming_sync) call the scheduler's execute_local_tools_async/execute_local_tools_sync without first appending an assistant message with tool_calls to the messages list. The scheduler's own docstring explicitly states the caller is responsible for this. The non-streaming paths (_execute_tool_calls at line 1204, _execute_tool_calls_sync at line 1229) correctly append {"role": "assistant", "tool_calls": ...} before calling the scheduler. The old streaming code also did this but the line was removed during the refactoring. This produces a malformed conversation (tool messages without a preceding assistant message), which will cause the API to reject subsequent requests.

Collected MCP tool results variable is never used

Low Severity

mcp_tool_results_from_server is assigned in both _execute_streaming_async and _execute_streaming_sync but is never read after assignment. The variable is dead code — the collected MCP tool results are silently discarded. Given the PR includes a fix for "inject server tool results into conversation for mixed tool calls," this may represent an incomplete implementation for the streaming paths.

Default by_alias change breaks request serialization of aliased fields

Medium Severity

The model_dump helper in _compat.py changed its by_alias default from hardcoded True to None (effectively False). The _transform_recursive function in _transform.py calls model_dump(data, exclude_unset=True, mode="json") without passing by_alias, relying on the previous default. This breaks serialization of Pydantic models with field aliases — notably JSONSchema.schema_ (aliased to "schema") will now serialize as "schema_" instead of "schema", sending incorrect field names to the API.

Bugbot Autofix prepared fixes for 1 of the 1 bugs found in the latest run.

✅ Fixed: Default by_alias change breaks request serialization of aliased fields
- Changed the by_alias parameter default from None to True in model_dump() to restore the original behavior where Pydantic field aliases are used during serialization.

Streaming tool results not recorded

Medium Severity

The streaming local-tool execution path passes fresh empty lists for tool_results and tools_called into execute_local_tools_async()/execute_local_tools_sync(), so successful executions in streaming mode are never reflected in the runner’s tracking structures.

Tool scheduler can collide on empty ids

High Severity

_parse_pending_calls() uses call_id = tc.get("id", "") as the TopologicalSorter node key and as the calls_by_id key. If any tool call lacks an id, multiple calls collapse onto the same empty-string id, overwriting entries and producing incorrect dependency ordering and tool_call_id references in emitted role="tool" messages.

…nt to env

Use v1-safe JSON alias/runtime handling and pydantic-v1 validators in MCP wire serialization, while keeping recursive TypeAliasType behavior for v2.
