Key improvements: - Add ChoiceJailState and ChoiceJailStateCollection for deterministic ordering - Implement independent per-choice jail/unjail logic - Add EmissionMode configuration (Packed vs SingleChoicePerChunk) - Support configurable emission patterns for OpenAI compatibility - Fix double emission issue during choice unjailing - Maintain backward compatibility for single-choice scenarios This addresses GitHub issues r2352198339 (determinism) and enables proper multi-choice (n>1) tool call handling with independent state management per choice index.

Core changes: - Add ChoiceEmission enum for clean emission abstraction - Add ChoiceJailState with encapsulated jail logic per choice - Replace HashMap with deterministic Vec-based ChoiceJailStateCollection - Implement independent process_content() method per choice - Add configurable EmissionMode (Packed vs SingleChoicePerChunk) - Clean separation between state management and emission strategy Key achievements: - Multi-choice independent jailing tests now pass - Deterministic choice ordering (always 0, 1, 2...) - Metadata preservation through jail processing - Maintains backward compatibility for single-choice scenarios Tests: 22/24 pass (2 trailing content edge cases remaining) Addresses GitHub issues: - r2352198339: HashMap determinism and independent choice jailing - Enables proper multi-choice (n>1) tool call handling --- .../protocols/openai/chat_completions/jail.rs | 596 ++++++++++++------ 1 file changed, 403 insertions(+), 193 deletions(-) diff --git a/lib/llm/src/protocols/openai/chat_completions/jail.rs b/lib/llm/src/protocols/openai/chat_completions/jail.rs index fe03038a69..f51c96338b 100644 --- a/lib/llm/src/protocols/openai/chat_completions/jail.rs +++ b/lib/llm/src/protocols/openai/chat_completions/jail.rs @@ -1,7 +1,7 @@ // SPDX-FileCopyrightText: Copyright (c) 2024-2025 NVIDIA CORPORATION & AFFILIATES.

This ensures trailing content after jail end markers is always emitted as separate chunks, fixing the failing tests: - test_jailed_stream_trailing_content_same_chunk - test_jailed_stream_early_exit_with_trailing Also remove unused methods to satisfy clippy warnings. All 24 jail tests now pass with the independent multi-choice jailing implementation.

Key improvements: - Added helper functions: assert_content, assert_tool_call, reconstruct_content - Documented expected input→output transformation in each test - Replaced complex .any()/.find() chains with index-based assertions - Added content reconstruction verification to ensure no data loss - Standardized test structure: chunk count → individual chunks → content reconstruction Tests now serve as executable documentation with immediate visual clarity of the stream processing behavior. When tests fail, developers know exactly which chunk contains the unexpected result. Updated tests: - test_partial_matching_suffix_detection: Shows cross-chunk detection - test_partial_matching_false_positive_prevention: Shows false positive handling - test_jailed_stream_no_jailing: Shows pass-through behavior - test_jailed_stream_empty_stream: Shows edge case handling - test_jailed_stream_multiple_tool_calls: Shows complex multi-tool behavior - test_jailed_stream_trailing_content_same_chunk: Shows trailing preservation All 26 jail tests continue to pass with enhanced clarity and debuggability.

The trie-based validation ensures optimal partial detection for streaming tool call marker recognition. All tests pass, confirming the implementation is robust.
