-VTC Response Stream Wrapper - Transform ProcessedResponse streams with VTC processing.
-
-This module provides a wrapper that applies VTC (Virtual Tool Calling) detection
-to AsyncIterator[ProcessedResponse] streams. It is designed for connectors like gemini_base
-that yield ProcessedResponse objects directly rather than raw SSE data.
-
-The wrapper:
-1. Extracts text content from OpenAI-format ProcessedResponse chunks
-2. Buffers until complete XML tool call patterns are detected
-3. Parses XML to internal tool call format
-4. Adds tool calls to metadata for reactor processing
-5. Invokes tool call reactor for detected calls
-6. Passes content through UNCHANGED - VTC clients expect their original XML format
-
-Note: Unlike the main VTC processors, this wrapper does NOT re-serialize tool calls.
-VTC clients like KiloCode handle their own XML format (e.g., )
-and expect it to pass through unchanged.

+VTC Response Stream Wrapper - Transform ProcessedResponse streams with VTC processing.
+
+This module provides a wrapper that applies VTC (Virtual Tool Calling) detection

+that yield ProcessedResponse objects directly rather than raw SSE data.
+
+The wrapper:
+1. Extracts text content from OpenAI-format ProcessedResponse chunks
+2. Buffers until complete XML tool call patterns are detected
+3. Parses XML to internal tool call format
+4. Adds tool calls to metadata for reactor processing
+5. Invokes tool call reactor for detected calls
+6. Passes content through UNCHANGED - VTC clients expect their original XML format
+
+Note: Unlike the main VTC processors, this wrapper does NOT re-serialize tool calls.
+VTC clients like KiloCode handle their own XML format (e.g., )
+and expect it to pass through unchanged.

-# Response Adapters Package
-
-This package contains the modular layer components for converting domain response objects to FastAPI/Starlette response objects. The architecture follows SOLID principles with clear separation of concerns, dependency injection, and independent testability.
-
-## Architecture Overview
-
-The adapters package is organized into focused layers, each handling a specific aspect of response transformation:
-
-```
-adapters/
-├── protocols.py # Protocol definitions for all layer contracts
-├── sse/ # SSE formatting and decoding
-├── metadata/ # Metadata injection (reasoning, etc.)
-├── usage/ # Usage normalization and header injection
-├── sanitization/ # Content and header sanitization
-├── capture/ # Wire capture coordination
-├── streaming/ # Streaming content conversion and buffering
-└── response/ # Response builders (JSON, Streaming, Other)
-```
-
-## Layer Components
-
-### SSE Layer (`sse/`)
-- **SSEFormatter**: Formats content as SSE bytes (`data: {json}\n\n`)
-- **SSEDecoder**: Decodes SSE-formatted payloads from various providers
-
-### Metadata Layer (`metadata/`)
-- **ReasoningInjector**: Injects reasoning metadata into OpenAI-style payloads
-
-### Usage Layer (`usage/`)
-- **UsageNormalizer**: Normalizes usage dictionaries to standard format
-- **UsageHeaderInjector**: Applies usage data as HTTP headers
-
-### Sanitization Layer (`sanitization/`)
-- **JSONSanitizer**: Ensures JSON-safe content (converts non-serializable objects)
-- **HeaderSanitizer**: Filters HTTP headers to allowed prefixes
-
-### Capture Layer (`capture/`)
-- **WireCaptureCoordinator**: Coordinates wire capture operations for debugging
-
-### Streaming Layer (`streaming/`)
-- **ToolBlockBuffer**: Buffers multiline tool blocks across streaming chunks
-- **StreamingContentConverter**: Converts raw stream chunks to StreamingContent
-
-### Response Layer (`response/`)
-- **JSONResponseBuilder**: Builds FastAPI JSONResponse
-- **StreamingResponseBuilder**: Builds FastAPI StreamingResponse
-- **OtherResponseBuilder**: Builds non-JSON responses
-
-## Usage
-
-The facade in `response_adapters.py` provides the public API:
-
-```python
-from src.core.transport.fastapi.response_adapters import domain_response_to_fastapi
-
-# Convert domain response to FastAPI response
-response = domain_response_to_fastapi(envelope, wire_capture=wire_capture, context=context)
-```
-
-## Dependency Injection
-
-All layer components support dependency injection via constructor parameters, with fallback to default instances when DI is unavailable:
-
-```python
-# With DI
-json_builder = JSONResponseBuilder(
- json_sanitizer=my_sanitizer,
- header_sanitizer=my_header_sanitizer,
- usage_header_injector=my_injector,
-)
-
-# Without DI (uses defaults)
-json_builder = JSONResponseBuilder()
-```
-
-## Protocol Contracts
-
-All layer components implement protocols defined in `protocols.py`. This enables:
-- Type checking and IDE support
-- Runtime protocol compliance verification
-- Easy mocking in tests
-
-## Testing
-
-Each layer has dedicated unit tests in `tests/unit/transport/fastapi/adapters/`. Integration tests verify the full pipeline in `tests/integration/transport/fastapi/`.
-
-## Migration Notes
-
-The original monolithic `response_adapters.py` (1851 lines) has been refactored into this modular structure. The facade maintains 100% backward compatibility with existing callers.

-These tests verify that streaming contract conversions do not introduce
-buffering that impacts time-to-first-byte or streaming throughput.
-
-Requirement 5.4: While streaming responses are processed, the LLM Proxy
-shall avoid buffering entire streams solely for contract conversion or mutation.
-
-NFR1.1: Avoid deep-copy behavior for large request/response payloads.
-NFR1.2: Avoid buffering that increases time-to-first-byte.
-NFR1.3: Preserve copy-on-write behavior for contract updates.

-Regression test for Windows double-ampersand fixer client_os propagation.
-
-This test verifies that client_os is correctly propagated through the streaming
-pipeline to the ToolCallReactorFeature, enabling the WindowsDoubleAmpersandFixer
-to replace && with ; in Execute tool calls for Windows clients.
-
-Bug Description:
-- RequestProcessorService correctly detects client_os and stores it in
- context.processing_context.values["client_os"]
-- However, the streaming pipeline did NOT propagate this value to the
- MiddlewareApplicationProcessor context dict
-- As a result, ToolCallReactorFeature received client_os=None and skipped
- the && replacement, causing PowerShell errors on Windows
-
-Fix:
-- BackendRequestManager._attach_stream_context() now extracts client_os from

-- MiddlewareApplicationProcessor.process() now extracts client_os from
- content.metadata and adds it to the context dict

-# Middleware Property Tests Summary
-
-This document summarizes the property-based tests implemented for Task 22 of the streaming-pipeline-refactor spec.
-
-## Overview
-
-Three key properties were implemented to verify the correctness of the streaming middleware architecture:
-
-1. **Property 20: Metadata Enrichment Safety** - Validates Requirements 7.4
-2. **Property 24: Backend Logic Isolation** - Validates Requirements 8.4
-3. **Property 25: Infrastructure Reuse** - Validates Requirements 8.5
-
-## Test Implementation
-
-### Property 20: Metadata Enrichment Safety
-
-**Location**: `tests/property/test_streaming_middleware_properties.py::TestMetadataEnrichmentSafety`
-
-**Purpose**: Ensures that middleware that adds metadata to chunks does so safely without buffering or breaking the stream.
-
-**Tests Implemented**:
-
-1. `test_metadata_enrichment_does_not_buffer_stream`
- - Verifies all chunks are yielded incrementally (no buffering)
- - Confirms stream continues to completion
- - Validates metadata enrichment doesn't block chunk emission
-
-2. `test_metadata_enrichment_preserves_chunk_structure`
- - Ensures metadata enrichment only modifies the metadata field
- - Verifies content, flags, and stream_id remain unchanged
- - Confirms chunk structure integrity
-
-3. `test_metadata_enrichment_incremental_processing`
- - Validates chunks are processed in order
- - Ensures incremental processing without waiting for stream completion
- - Verifies no buffering or reordering occurs
-
-**Key Insight**: Middleware must process chunks as they arrive without accumulating them in memory, ensuring constant memory usage and low latency.
-
-### Property 24: Backend Logic Isolation
-
-**Location**: `tests/property/test_streaming_middleware_properties.py::TestBackendLogicIsolation`
-
-**Purpose**: Ensures middleware processors work uniformly across all backends without special-casing provider-specific behavior.
-
-**Tests Implemented**:
-
-1. `test_middleware_does_not_contain_backend_specific_logic`
- - Tests middleware with multiple providers (openai, anthropic, gemini, test, custom)
- - Verifies identical processing regardless of provider
- - Confirms provider metadata is preserved
-
-2. `test_middleware_processes_any_provider_uniformly`
- - Validates uniform processing across all providers
- - Ensures no provider-specific branches in middleware
- - Confirms consistent behavior for unknown providers
-
-**Key Insight**: Backend-specific logic must remain in normalizers, not in middleware. This ensures middleware can be reused across all backends without modification.
-
-### Property 25: Infrastructure Reuse
-
-**Location**: `tests/property/test_streaming_middleware_properties.py::TestInfrastructureReuse`
-
-**Purpose**: Verifies that common infrastructure (processors, assemblers, metrics) can be shared across all backends without duplication.
-
-**Tests Implemented**:
-
-1. `test_common_infrastructure_works_for_all_backends`
- - Tests shared processor chain with chunks from different backends
- - Verifies infrastructure works identically for all providers
- - Confirms no backend-specific infrastructure needed
-
-2. `test_processor_chain_reusable_across_backends`
- - Validates multi-stage processor chains work for all backends
- - Ensures chain composition is provider-agnostic
- - Confirms consistent results across providers
-
-3. `test_infrastructure_components_provider_agnostic`
- - Tests that infrastructure components don't need provider knowledge
- - Verifies components work with unknown/custom providers
- - Confirms true provider independence
-
-**Key Insight**: Infrastructure components should be completely provider-agnostic, enabling code reuse and preventing duplication across backend implementations.
-
-## Test Configuration
-
-All tests use Hypothesis for property-based testing with the following configuration:
-
-- **Max Examples**: 100 iterations per test
-- **Deadline**: None (allows async operations to complete)
-- **Health Checks**: Suppressed for slow tests and large data
-
-## Additional Property Suites (2025-11-24)
-
-The following property test batteries were added to cover the remaining design
-properties from `.kiro/specs/streaming-pipeline-refactor/design.md`:
-
-| Module | Properties Covered |
-| --- | --- |
-| `tests/property/test_streaming_contract_properties.py` | 1, 3, 4, 9, 17, 18, 19, 21 |
-| `tests/property/test_streaming_sentinel_properties.py` | 2, 14, 15, 16 |
-| `tests/property/test_streaming_error_properties.py` | 10, 11 |
-| `tests/property/test_streaming_protocol_properties.py` | 5 |
-| `tests/property/test_streaming_metrics_properties.py` | 13 |
-| `tests/property/test_streaming_logging_properties.py` | 12, 29 |
-| `tests/property/test_streaming_memory_properties.py` | 26 |
-| `tests/property/test_streaming_async_properties.py` | 27, 28 |
-
-These suites run under the shared `tests/property` package and are now part of
-the CI gate for the `feat-streaming-refactor` branch.
-
-## Test Results
-
-All property tests currently pass:
-
-```
-$ .venv/Scripts/python.exe -m pytest tests/property
-============================= 28 passed in XX.XXs =============================
-```
-
-## Architecture Validation
-
-These property tests validate critical architectural principles:
-
-1. **Separation of Concerns**: Middleware is isolated from backend-specific logic
-2. **Incremental Processing**: Chunks flow through the pipeline without buffering
-3. **Provider Independence**: Infrastructure works uniformly across all backends
-4. **Code Reuse**: Common components are shared without duplication
-
-## Future Considerations
-
-These tests establish a foundation for:
-
-- Adding new backends without modifying middleware
-- Composing middleware chains without provider-specific branches
-- Maintaining constant memory usage in streaming operations
-- Ensuring consistent behavior across all providers
-

+
+## Test Results
+
+All property tests currently pass:
+
+```
+$ .venv/Scripts/python.exe -m pytest tests/property
+============================= 28 passed in XX.XXs =============================
+```
+
+## Architecture Validation
+
+These property tests validate critical architectural principles:
+
+1. **Separation of Concerns**: Middleware is isolated from backend-specific logic
+2. **Incremental Processing**: Chunks flow through the pipeline without buffering
+3. **Provider Independence**: Infrastructure works uniformly across all backends
+4. **Code Reuse**: Common components are shared without duplication
+
+## Future Considerations
+
+These tests establish a foundation for:
+
+- Adding new backends without modifying middleware
+- Composing middleware chains without provider-specific branches
+- Maintaining constant memory usage in streaming operations
+- Ensuring consistent behavior across all providers
+

-These tests ensure that when quality verifier is configured but not running,

-
-Background:
-Quality verifier was configured but not running. No visibility into why.
-The issue was that replacement model being active caused quality verifier

+Background:
+Quality verifier was configured but not running. No visibility into why.

-"""
-Regression tests for Fix 2: Extended Fallback Logic for Preparation-Phase Errors.
-
-These tests ensure that when a replacement model fails during request preparation
-(e.g., OAuth token refresh), the fallback logic catches the error and automatically
-retries with the original model, following B2BUA-like session isolation patterns.
-
-Background:
-Fallback logic only caught errors during backend execution, not during preparation.
-When OAuth token refresh failed in the replacement model's connector during
-preparation, the error propagated to clients, interrupting all sessions.
-
-The fix extends the try-catch to cover both preparation AND execution phases,
-and ensures proper B2BUA identity allocation (new b_session_id) for fallback attempts.
-
-Issue: https://github.com/.../issues/...
-Fixed in: Session 2026-02-26

+Regression tests for Fix 2: Extended Fallback Logic for Preparation-Phase Errors.
+
+These tests ensure that when a replacement model fails during request preparation
+(e.g., OAuth token refresh), the fallback logic catches the error and automatically
+retries with the original model, following B2BUA-like session isolation patterns.
+
+Background:
+Fallback logic only caught errors during backend execution, not during preparation.
+When OAuth token refresh failed in the replacement model's connector during
+preparation, the error propagated to clients, interrupting all sessions.
+
+The fix extends the try-catch to cover both preparation AND execution phases,
+and ensures proper B2BUA identity allocation (new b_session_id) for fallback attempts.
+
+Issue: https://github.com/.../issues/...

-"""
-Regression tests for CRITICAL streaming error response fallback bug.
-
-ROOT CAUSE OF PRODUCTION ISSUE (2026-02-26):
-When using streaming APIs, BackendCompletionFlowService returns StreamingResponseEnvelope
-with error status codes (401, 500, etc.) instead of raising exceptions.
-
-The original fallback logic ONLY caught exceptions, so streaming error envelopes
-bypassed the fallback entirely and were sent directly to clients, causing:
-1. Session interruptions
-2. Stringified SSE markers like "data: [DONE]" visible to users
-3. No automatic retry with original model
-
-THE FIX:
-Added detection in request_processor_service.py to convert error envelopes
-to exceptions BEFORE returning, so the existing exception-based fallback logic
-can catch and handle them.
-
-This test file ensures this critical case is covered and will catch regressions.
-
-Issue: OAuth rate limiting on replacement models causing universal session failures
-Fixed in: Session 2026-02-26 (second iteration)

+Regression tests for CRITICAL streaming error response fallback bug.
+
+ROOT CAUSE OF PRODUCTION ISSUE (2026-02-26):
+When using streaming APIs, BackendCompletionFlowService returns StreamingResponseEnvelope
+with error status codes (401, 500, etc.) instead of raising exceptions.
+
+The original fallback logic ONLY caught exceptions, so streaming error envelopes
+bypassed the fallback entirely and were sent directly to clients, causing:
+1. Session interruptions
+2. Stringified SSE markers like "data: [DONE]" visible to users
+3. No automatic retry with original model
+
+THE FIX:
+Added detection in request_processor_service.py to convert error envelopes
+to exceptions BEFORE returning, so the existing exception-based fallback logic
+can catch and handle them.
+
+This test file ensures this critical case is covered and will catch regressions.

+Regression tests for Fix 0: Streaming Error Response Formatting.
+
+These tests ensure that streaming requests receive proper SSE-formatted error responses,
+not JSON responses with stringified SSE markers like "data: [DONE]".
+
+Background:
+When concurrent clients hit OAuth rate limits during streaming requests, the proxy
+was returning JSON error responses that included stringified SSE markers, causing
+malformed output visible to clients.
+
+Issue: https://github.com/.../issues/...
