Without rehype-raw, ReactMarkdown escaped the raw <mark> HTML injected
by highlightTerms(), showing literal tags instead of yellow highlights.
Now 30 marks render with correct bg-yellow-200 (#FEF08A) background.
LegCo documents use multiple formats (問/答 markers, Q1/Q2 numbering,
section headings like '(1) 住戶的安置補償', 發言要點 bullet points,
and pure table pages). Regex alone cannot reliably classify all these.
Changes:
- Primary detection: LLM call identifies ALL section types in one pass
(qa, narrative, speaking_notes, table, toc, heading_only)
- Regex: downgraded to optional fast-pass optimization for known patterns
- Architecture diagram, algorithm detail, risks, and test plan all updated
- Single model handles structure detection + table extraction + verification
- New risk: vLLM may not support Qwen3.5-35B-A3B vision API depending on version
- Dependencies: added vLLM compatibility note with smoke test snippet
- Heuristic fallback (Option B) works regardless of OpenRouter or vLLM
- qa_vision_enabled toggle provides escape hatch
Root cause confirmed via vLLM docs, protocol.py source, RFC #19097, and
GitHub test suite: guided_json was removed in v0.12.0. Our fallback to it
after structured_outputs fails is dead code.
Fix strategy: replace _complete_structured_vllm() with two-tier approach
(response_format as Tier 1, structured_outputs as Tier 2), removing the
dead guided_json path and the chat_template_kwargs merge that may conflict.

DashScope realtime ASR sends utterance-completed (final) events
without incremental deltas. The onmessage handler cleared
partialTranscript on every final, so text never appeared.
Set partialTranscript to full_text on final messages instead
of clearing it, keeping the transcript visible in QueryInput.
useMediaStreamASR cleanup() cleared partialTranscript on stop,
causing live ASR text to vanish from QueryInput. Unlike video
ASR (which has onFinalTranscript to persist via queryText),
mic and system-audio hooks rely on partialTranscript for
display. Keep partialTranscript populated with the final
transcript instead of clearing it.
Adds two new live audio sources alongside file Upload:
- System Audio: getDisplayMedia() captures system/tab audio output,
pipes through WebSocket → DashScope realtime ASR → RAG.
- Listen Mic: getUserMedia() captures microphone input via the same
audio pipeline (shared useMediaStreamASR hook).
Backend: feature toggles (system_audio_enabled, mic_enabled) in
config.py, source query param gating in ws_asr.py, 10 config tests.
Bug fix: getDisplayMedia() rejected video:false per W3C spec —
changed to video:true then stop video tracks to allow audio-only
capture on Windows/macOS Chrome.
isDisabled, handleSubmit, and Half Question onClick all checked
question.trim() instead of displayValue.trim(). Since question state
is only updated on onFinalTranscript (complete sentences), interim
ASR delta text shown in the textarea via partialText was invisible
to the disabled check — buttons stayed disabled until sentence end.
Fix: use displayValue which includes partialText when user hasn't typed.
- Backend: add stop_after_decompose flag to QueryRequest, early-return
after decomposition in SSE stream with half_question:true event
- Frontend: add decomposeOnly method to useQueryDocumentStream hook
- QueryInput: remove grey italic from ASR partial text, rename Submit
to Final Submit, add gray Half Question button that decomposes
without clearing querybox text
- LTTPage: wire handleHalfQuestion to decomposeOnly
Reverts commits 284028b through b4096d6. Phase 4 (System Audio Capture)
will replace the YouTube use case with a more versatile getDisplayMedia approach.
Removed: YouTube router, HLS proxy, YouTubeService, YouTubeInput,
YouTubeVideoPlayer, useYouTubeASR hook, all Phase 3 tests, hls.js dep,
YouTube config fields, YouTube README/plan sections.
Modified files restored to pre-Phase-3 state: LTTPage (no source toggle),
api.ts (no YouTube extract), types (no YouTube types), config.py (no
youtube fields), main.py (no YouTube router), requirements.txt (no yt-dlp),
.env.example (no YouTube vars), package.json (no hls.js).
Relevant Phase 2 code preserved: ws_asr.py (unchanged), useVideoASR,
VideoPlayer, VideoUpload, QueryInput, Full Transcript.
Replace full_text responses with character-level deltas computed from
DashScope's monotonically-growing 'text' field. Stash-only events (empty
text) are skipped; trailing stash chars sent alongside deltas and
appended on pause to complete final sentences.
Backend:
- Delta = text[len(prev_text):] — simple suffix diff, no merge logic
- Track item_id for utterance boundaries, prepend space separator
- Send stash alongside delta for frontend pause handler
Frontend:
- Accumulate deltas locally (transcriptRef += msg.delta)
- Store lastStashRef from each message
- On pause: append stash to text, fire onFinalTranscript
Plan: .plans/phase2_enhancement_delta_sse.md updated to Complete
DashScope stashes are ~7-char rolling windows, not cumulative. Each partial
event replaces the previous. Completed events rarely sent. This caused text to
jump/replace during streaming and disappear on pause.
Backend:
- Add _merge_stash() — finds overlapping suffix between successive stashes
and appends only new characters, reconstructing full utterance from partials
- format_transcription_event returns raw stash for read_events to merge
- read_events maintains partial_buffer via _merge_stash, clears on completed
- Guard against empty/whitespace-only stashes
Frontend:
- transcriptRef + onFinalTranscriptRef avoid stale closures in pause handler
- stopStreaming fires onFinalTranscript(currentText) before clearing partial
- Removed blind setPartialTranscript('') that erased text on pause
Tests: 16/16 ws_protocol tests pass, frontend tests unchanged
Plan: Updated phase2_implementation_plan.md to Complete with 11-bug log
- Add DashScope ASR and video upload config fields to Settings
- Create Pydantic models (video.py, asr.py)
- Create VideoService with validation, save, serve, delete
- Create ASR client stub with float32_to_s16le utility
- Implement POST /api/v1/video/upload with streaming validation
- Implement GET /api/v1/video/{video_id} with FileResponse
- Create WebSocket ASR endpoint stub
- Register new routers in main.py
- Update .env.example and requirements.txt
- Add reference examples for DashScope integration
- 8 tests passing (3 config + 5 video upload)
Follows Deepseek JSON Output guide: the prompt now includes the word 'json' and a format example derived from the Pydantic model schema. Added _pydantic_to_json_instruction() helper that builds a human-readable schema description with EXAMPLE JSON OUTPUT.

Added complete_structured() to mock classes, split response lists between LLMClientDP (decompose) and LLMClient (filter+generate), and patched both clients in all integration tests.

QueryDecomposer now uses LLMClientDP (Deepseek) while RelevanceFilter and RAGService continue using LLMClient (OpenRouter/vLLM).

Uses Deepseek's json_object response_format (not json_schema, which Deepseek does not support). Always disables thinking mode. Includes unit tests (12) and acceptance tests (5).
