WalkthroughOpenAI streaming block lookup now uses output indices for reasoning and tool-call blocks, and output plus content indices for text blocks. Partial text extraction sorts text blocks by output index and then content index. Added SSE tests cover changing provider item IDs, separate text parts, reasoning summaries, tool progress, and partial text ordering.

🟡 Minor · Order partial text blocks by output and content index. · openai-backend.go:689-696

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winOrder partial text blocks by output and content index.
extractPartialTextFromStateiterates overstate.blockMap, and Go map iteration order is random. Before this change, text parts in one output item shared an item-ID key, so at most one text block per item existed. Now every(outputIndex, contentIndex)pair has its own block. A canceled stream with more than one text part therefore saves itsoutput_textcontents in random order. The saved partial assistant message can show the text in the wrong sequence. To fix this, collect the text keys and sort them byoutputIndex, then bycontentIndex, before buildingtextContent.🐛 Proposed fix
func extractPartialTextFromState(state *openaiStreamingState) []*OpenAIChatMessage { var textContent []OpenAIMessageContent - - for _, blockState := range state.blockMap { - if blockState.kind == openaiBlockText && blockState.accumulatedText != "" { + keys := make([]openaiBlockKey, 0, len(state.blockMap)) + for key, blockState := range state.blockMap { + if blockState.kind == openaiBlockText && blockState.accumulatedText != "" { + keys = append(keys, key) + } + } + sort.Slice(keys, func(i, j int) bool { + if keys[i].outputIndex != keys[j].outputIndex { + return keys[i].outputIndex < keys[j].outputIndex + } + return keys[i].contentIndex < keys[j].contentIndex + }) + for _, key := range keys { + blockState := state.blockMap[key] + { textContent = append(textContent, OpenAIMessageContent{ Type: "output_text", Text: blockState.accumulatedText, }) } }🤖 Prompt for AI Agents

Responses-compatible endpoints can return fresh
item_idvalues for events belonging to the same output item. Wave currently keys streaming blocks by that ID, so it silently drops text deltas, reasoning summaries, and tool-progress updates when IDs differ. A request can complete successfully and report token usage while displaying an empty answer.This change identifies reasoning/tool blocks by
output_indexand text blocks by(output_index, content_index). Local UI IDs stay consistent across start/delta/end events, and separate text parts in one message no longer overwrite each other. Partial replies saved on cancellation preserve output/content order.Affected implementations
content_part.added,output_text.delta, andcontent_part.donewhile keeping the same output/content indices. The same behavior is independently documented in BerriAI/litellm#30071.The fix applies to the existing Responses backend regardless of provider and does not add a provider or change authentication.
