+# 無法 git pull 的處理方式
+
+## 方式一：透過 bundle 檔案
+
+M5 已產出 bundle 檔：`/Users/accusys/momentry_core_0.1/m5_updates.bundle`
+
+在 M4 上執行：
+```bash
+cd /Users/accusys/momentry_core_0.1
+
+# 把 m5_updates.bundle 放到這裡後：
+git fetch m5_updates.bundle main:main
+```
+
+## 方式二：手動複製檔案
+
+以下是最新的 3 個 commit 包含的檔案變更：
+
+### Commit `9f5afd1` — file-based source of truth
+```
+src/worker/job_worker.rs          ← file check + backup 機制
+src/core/processor/executor.rs    ← partial → .json.partial
+scripts/start_momentry.sh         ← startup 修正
+docs/M4_RELEASE_INCIDENT_2026-05-09.md
+docs/M4_M5_COLLABORATION_PROTOCOL.md
+```
+
+### Commit `b902763` — trace chunks + co-appearance
+```
+src/core/chunk/trace_ingest.rs    ← 新檔：trace chunk ingestion
+src/core/chunk/mod.rs             ← 註冊 trace_ingest
+src/worker/job_worker.rs          ← 觸發 trace chunk 產生
+src/api/universal_search.rs       ← chunk_type + co_appears_with filter
+docs/TRACE_SEARCH_API_DESIGN.md
+```
+
+### Commit `a0774cb` — TKG pipeline integration
+```
+scripts/tkg_builder.py            ← 新增 face-face CO_OCCURS_WITH edges

+docs_v1.0/M4_workspace/2026-05-09_TKG_integration.md
+```
+
+## worker binary 也要更新
+
+M5 已 build 新的 `target/debug/momentry_playground`，M4 也需要 rebuild：
+```bash
+cd /Users/accusys/momentry_core_0.1 && cargo build --bin momentry_playground
+```
