Fix: switch DEFAULT_MODEL from tencent/hy3:free (unavailable on OpenRouter) to laguna-s-2.1:free

tencent/hy3:free returns OpenRouter 404: 'This model is unavailable for free.
The paid version is available now - use this slug instead: tencent/hy3'

This caused /api/session/restore-summary to return 500 (seed_from_summary
calls LLM with DEFAULT_MODEL_PATH). Switched to poolside/laguna-s-2.1:free
which is available on OpenRouter free tier.

+# Auto-Continue Feature for Free Models
+
+## Tổng quan
+Khi model miễn phí dùng OpenRouter phản hồi bị dừng nhưng nhiệm vụ chưa hoàn thành, hệ thống sẽ:
+1. Phát hiện task incomplete dựa vào trạng thái plan
+2. Hiển thị 2 nút: "Tự động tiếp tục (10s)" và "Tạm dừng"
+
+## Các file cần sửa
+
+### 1. frontend/src/hooks/useAgentChat.ts
+
+```typescript
+// Thêm vào import
+import { useCallback, useEffect, useMemo, useRef, useState } from 'react';
+
+// Trong useAgentChat function, sau callbacksRef
+const autoContinueTimerRef = useRef<ReturnType<typeof setTimeout> | null>(null);
+const [showAutoContinue, setShowAutoContinue] = useState(false);
+const [taskIncompleteInfo, setTaskIncompleteInfo] = useState<{

+    clearTimeout(autoContinueTimerRef.current);
+  }
+  autoContinueTimerRef.current = setTimeout(() => {
+    startAutoContinue();
+  }, 10000);
+},
+
+// Thêm hàm mới
+const startAutoContinue = useCallback(() => {
+  setShowAutoContinue(false);
+  setTaskIncompleteInfo(null);
+  if (autoContinueTimerRef.current) {
+    clearTimeout(autoContinueTimerRef.current);
+    autoContinueTimerRef.current = null;
+  }
+  const incompleteItems = taskIncompleteInfo?.incompletePlan || [];
+  const continuationText = incompleteItems.length > 0
+    ? `Tiếp tục từ các task chưa hoàn thành: ${incompleteItems.map(i => `- ${i.content}`).join('\n')}`
+    : 'Tiếp tục nhiệm vụ.';

+  editAndRegenerate,
+  approveTools,
+  refreshMessages,
+  showAutoContinue,
+  taskIncompleteInfo,
+  startAutoContinue,
+  cancelAutoContinue,
+};
+```
+
+### 2. frontend/src/components/Chat/ChatInput.tsx
+
+```typescript
+// Thêm import
+import { Box, IconButton, Stack, Tooltip, Button } from '@mui/material';
+
+// Thêm props
+interface ChatInputProps {
+  // ... existing props
+  showAutoContinue?: boolean;
+  taskIncompleteInfo?: { incompletePlan: Array<{ id: string; content: string; status: string }> } | null;
+  startAutoContinue?: () => void;
+  cancelAutoContinue?: () => void;
+}
+
+// Thêm UI buttons (trước hoặc sau input area)
+{showAutoContinue && taskIncompleteInfo && (
+  <Stack direction="row" spacing={1} sx={{ mb: 1, px: 2 }}>
+    <Button
+      variant="contained"
+      color="primary"
+      size="small"
+      onClick={startAutoContinue}
+      sx={{ textTransform: 'none' }}
+    >
+      Tự động tiếp tục (10s)
+    </Button>
+    <Button
+      variant="outlined"
+      color="secondary"
+      size="small"
+      onClick={cancelAutoContinue}
+      sx={{ textTransform: 'none' }}
+    >
+      Tạm dừng
+    </Button>
+  </Stack>
+)}
+```
+
+### 3. frontend/src/lib/sse-chat-transport.ts
+
+```typescript
+// Thêm vào case trong createEventToChunkStream
+case 'task_incomplete':
+  sideChannel.onTaskIncomplete(
+    (event.data?.incomplete_plan as Array<{ id: string; content: string; status: string }>) || [],
+  );
+  break;
+```
+
+### 4. agent/core/agent_loop.py
+
+```python
+# Trong run_agent, sau khi xử lý LLM response
+def _check_task_incomplete(session: Session, llm_result: LLMResult) -> bool:
+    """Kiểm tra nếu model dừng nhưng task chưa hoàn thành."""
+    if llm_result.tool_calls_acc:
+        return False  # Có tool calls thì chưa incomplete
+    
+    plan = getattr(session, "current_plan", None) or []
+    unfinished = [item for item in plan if item.get("status") in ("pending", "in_progress")]
+    
+    return len(unfinished) > 0
+
+# Gọi sau khi nhận kết quả LLM:
+if _check_task_incomplete(session, llm_result):
+    unfinished = [item for item in plan if item.get("status") in ("pending", "in_progress")]
+    await session.send_event(
+        Event(
+            event_type="task_incomplete",
+            data={
+                "incomplete_plan": unfinished,
+                "message": "Model stopped streaming but task is incomplete."
+            }
+        )
+    )
+```
+
+## Logic hoạt động
+
+1. Khi agent loop phát hiện model trả lời không có tool calls nhưng plan còn incomplete
+2. Backend gửi event `task_incomplete` với danh sách task chưa hoàn thành
+3. Frontend nhận event qua `onTaskIncomplete` callback
+4. Hiển thị 2 nút:
+   - **Tự động tiếp tục (10s)**: Sau 10 giây sẽ tự động gửi tin nhắn tiếp tục
+   - **Tạm dừng**: Hủy timer, cho phép user nhập nội dung mới
+

+# Space Multiverse — ML Intern V2
+
+## 🔒 Permanent Session & User Context Logging
+
+**Lưu trữ vĩnh viễn ngữ cảnh từng phiên và từng user vào dataset HuggingFace.**
+
+- Mỗi message, tool call, event được lưu **ngay khi xảy ra** — không đợi heartbeat
+- Không bao giờ mất dữ liệu, ngay cả khi Space restart/crash
+- Lưu vào `bep40/ml-intern-sessions` (dataset chung) + `{user}/ml-intern-sessions` (cá nhân)
+- Mỗi model (dù là model nào) đều được lưu session vĩnh viễn
+- **Không có thông báo "where we here now?"** — giảm thiểu thông báo không cần thiết
+
+### Cách hoạt động
+
+1. Khi session được tạo → log ngay vào dataset với event_type=session_created
+2. User gửi tin nhắn → log ngay role=user, event_type=message
+3. Agent phản hồi → log ngay role=assistant, event_type=message
+4. Tool call/result → log ngay event_type=tool_call/tool_result
+5. Session kết thúc → log trajectory đầy đủ
+
+### Truy cập lịch sử
+
+- `GET /api/sessions-history` — lấy tất cả session của user
+- `GET /api/session-history/{session_id}` — lấy full lịch sử một session
+- `GET /api/dataset-info` — thông tin dataset lưu trữ
+
+Dataset: [bep40/ml-intern-sessions](https://huggingface.co/datasets/bep40/ml-intern-sessions)
+
+## Models
+
+- **Default**: `openai/tencent/hy3:free`
+- OpenRouter models: Tencent HY3, Gemma 4 31B, Llama 3.3 70B, DeepSeek V4, Laguna S 2.1
+- BeatAPI: `beatapi/space-bunny-alpha` (provider riêng, cần BEATAPI_API_KEY)
+- Cục bản chất, mọi model đều được lưu session vĩnh viễn
+
+## Quick Start
+
+1. Chọn model (dùng bất kỳ model nào — đều được lưu)
+2. Chat bình thường
+3. Session được lưu vĩnh viễn vào dataset
+4. Sau Space restart, frontend tự động restore từ dataset

+"""Extract plain-text context from uploaded office/binary documents.
+
+The ML Intern agent runtime is a coding agent that mostly runs on text-only
+LLM backends (many of the free OpenRouter models have no vision). So instead
+of just handing the raw binary file to the model, we extract the meaningful
+text out of it and present it as a compact, readable context block.
+
+Supported formats:
+    PDF             (.pdf)
+    Images          (.png, .jpg, .jpeg, .webp, .bmp, .tiff, .gif)
+    Excel           (.xlsx, .xlsm, .xls)
+    Word            (.docx)
+    PowerPoint      (.pptx)
+    OpenDocument    (.odt, .ods, .odp)          (via LibreOffice)
+    Plain text      (.txt, .md, .csv, .json, .jsonl, .rtf, .log)
+
+IMPORTANT: For OCR we rely on pytesseract + a system tesseract binary.
+For legacy binary office formats (.xls, .doc, .rtf, .odt/.ods/.odp) we rely
+on LibreOffice headless (`libreoffice --headless --convert-to txt`). If those
+system binaries are not installed, extraction degrades gracefully: the file is
+still uploaded and referenced, but with a warning that the raw content could
+not be parsed.

+    "openai/space-bunny-alpha" or "openai/stealth/space-bunny-alpha" 404s;
+  - uses `space-bunny-alpha` as a *flat* model id, so we must strip our own
+    `beatapi/` routing prefix before the request leaves the app;
+  - rate-limits the free tier (1 req/min before first top-up, 10/min after,
+    1000/day) and returns HTTP 429 with Retry-After.
+
+Therefore BeatAPI models use the `beatapi/` prefix -- a namespace nothing else
+uses -- so this branch can never be shadowed by the `openai/` catch-all, and
+the OpenRouter branch can never accidentally strip a BeatAPI model id.
+
+If BEATAPI_API_KEY is unset we raise a clear, actionable error instead of
+silently sending an empty key (which BeatAPI answers with a bare 401
+missing_api_key).
+
+Runs AFTER patch_models.py and patch_openrouter_fix.py. Idempotent.

+Patch: Fix 404 on root and /api when frontend build is missing.

+Root cause: The Dockerfile creates /app/static with `mkdir -p` but the

+`if static_path.exists()` which returns True for an empty directory,
+causing StaticFiles to mount at "/" and shadow ALL API routes with 404s.

+"""Patch: lossless long-context memory — fix context loss in long sessions/jobs.
+
+Applied during Docker build. Idempotent. NEVER fails the build.
+
+Root causes fixed:
+ 1. compact() deleted the middle incl. ALL tool results (model continued a long
+    job from a terse paraphrase)
+ 2. CompactionFailedError TERMINATED the session mid-job (_compact_and_notify)
+ 3. restore_session_from_log reloaded history VERBATIM -> next compaction
+    nuked the tool trail or killed the session
+ 4. max_iterations=300 silently stopped long jobs
+
+Fixes:
+ A. compact(): snapshot removed middle (raw tool calls/results) into
+    cm.compaction_archive before rewriting items — the raw trail survives.
+ B. untouched_messages default 5 -> 24 (keep more of the recent working set).
+ C. cm.prune_to_fit(): drop oldest tool outputs (markers) until under
+    threshold. agent_loop _compact_and_notify calls it on CompactionFailedError
+    instead of terminating — degrade, never kill.
+ D. restore_session_from_log: normalize restored history to 70% headroom
+    (trim oldest tool outputs, keep system/first_user/tail).
+ E. config max_iterations default -1 (unlimited) + untouched_messages=24;
+    session.py reads config.untouched_messages.

+"""Patch backend: OpenRouter routing + DeepSeek V4 Flash 0731 + FIX DeepSeek routing.
+
+FIX: GLM_52_MODEL_ID was set to "openai/deepseek/deepseek-v4-flash" which routes
+to OpenRouter via the openai/ prefix catch-all. However, OpenRouter's model ID
+is "deepseek/deepseek-v4-flash" (without the openai/ prefix). When LiteLLM
+sends the full "openai/deepseek/deepseek-v4-flash" as the model name to
+OpenRouter's API, it gets a 404 because OpenRouter doesn't recognize the
+"openai/" prefix.
+
+Solution:
+1. GLM_52_MODEL_ID -> "deepseek-ai/DeepSeek-V4-Flash:deepinfra" (HF Router path, model exists there, cheapest provider)
+2. OpenRouter routing strips the "openai/" prefix before sending to OpenRouter
+3. Add :novita tag to DeepSeek V4 Pro for deterministic routing via HF Router
+4. Add stealth/space-bunny-alpha using the same OpenRouter-style prefix.

+"""Patch backend llm_params.py: force OpenRouter as the LiteLLM provider.
+
+Root cause: the openai/-prefixed (and deepseek/) model routing returns only
+``api_base`` + ``api_key``. LiteLLM resolves the provider from the model
+string's org prefix, so for models whose org is NOT a recognized LiteLLM
+provider (upstage/, nvidia/, liquid/, meta-llama/, google/, poolside/,
+inclusionai/, ...) it raises "LLM Provider NOT provided" even though
+``api_base`` points at OpenRouter. Only orgs that happen to match a real
+LiteLLM provider (e.g. tencent/) worked by luck.
+
+Fix: add ``custom_llm_provider: "openrouter"`` to both OpenRouter routing
+branches so LiteLLM always uses the OpenRouter OpenAI-compatible client.
+
+This runs AFTER patch_models.py (which may already have inserted the routing
+blocks); it is idempotent.
