+- **Báo cáo user:** play ở MAIN → chuyển SECTION-TAB check item đang play → VU meter không animation realtime.
+- **Nguyên nhân (2 lỗi):** (1) VU tick (24603) lookup `trackNodes[trackId]` — key THƯỜNG — node của section tab là SUB-NODE (key `<parent>_sub_<trackId>`) → không khớp → node undefined; (2) sub-node KHÔNG có `analyserNode` (chỉ `{gainNode, pannerNode, route}`) → VU không có gì để đọc.
+- **FIX (app.jsx):** (1) VU tick — fallback scan `_sub_<trackId>` keys → vNode; đọc analyser từ `vNode.analyserNode`; (2) getOrCreateSubTrackNode — thêm `analyserNode` (gainNode → analyser → routeGain/dryGain) → VU đọc được tín hiệu section.

+- **Báo cáo user:** play MAIN → nhấp đôi vào section item → (1) VU meter animation không đúng nhịp âm thanh; (2) âm thanh MIDI item bị bypass qua mastering chain.
+- **Nguyên nhân:**
+  (1) **MIDI bypass**: sub-node routeGain nối vào PARENT NODE → qua route của parent track (parent `audio_bypass: true` → routeGain 0/dryGain 1) → MIDI/audio section bị kéo vào DRY bus dù sub-track ♪/A tắt → "bị bypass mastering".
+  (2) **VU không đúng nhịp**: scheduling MIDI của section item KHÔNG trigger `triggerMidiVuActivity` (main-track midi có ở 19066) → VU chỉ dựa analyser (trễ/smoothing) → không nhảy theo từng note.
+- **FIX (app.jsx):**
+  (1) getOrCreateSubTrackNode — mastering path `routeGain.connect(window.masterBus.input)` TRỰC TIẾP (không qua parent — parent route có bypass riêng); fallback parentNode khi không có masterBus.
+  (2) Section midi scheduling (19182) — thêm `triggerMidiVuActivity(subTrack.id, note.velocity)` sau mỗi playNote.

+- **Báo cáo user (kèm log):** nhấp đôi section → `setOutputDestination to: track node (sfEntry)` + noteon chạy nhưng MIDI bị bypass mastering.
+- **Nguyên nhân:** SECTION-TAB play dùng PLAIN node (getOrCreateTrackNode) → `createMasteringRoute` đọc `trackAudioBypassMap`/`track.audioBypass` — section track default `audio_bypass: true` (round 48) → route dry → **MIDI kéo vào dry bus dù ♪ tắt**.

+- **FIX (app.jsx createMasteringRoute):** bypass theo LOẠI nội dung — track **MIDI-only** (midiItems, không clips/buffer) → dùng `trackMidiBypassMap`/`midiBypass` (♪); track có clips → `audioBypass` (A) như cũ.

+- **Báo cáo user:** (1) nhấp đôi section → play lần ĐẦU midi bị bypass; stop + play lại → đúng. (2) play section item trên track → VU track đó không animation.
+- **Nguyên nhân:**
+  (1) **Node STALE**: section tab track id TRÙNG main track id — node tạo từ MAIN play (route theo data main — audioBypass=true → dry) được cache lại → first play trong section tab dùng node cũ → bypass; stop (wipe nodes) → play lại → node mới đúng.
+  (2) **VU track main**: âm section đi thẳng masterBus.input (fix 00:30) → KHÔNG qua node chính → analyser node chính không có tín hiệu → VU đứng yên.

+  (1) Helper `routeBypassFor(track)` (bypass theo content-type — MIDI-only → ♪, có clips → A) — áp: createMasteringRoute (đã có), startTrackPlayback re-apply route mỗi lần schedule (hết stale), mastering-settings effect (14906 thay effAudioBypass).
+  (2) VU tick — scan sub-nodes (`k.indexOf(trackId + '_sub_') === 0`) khi node chính không có tín hiệu → peak sub-node analyser → VU track main animation theo section.

+- **Báo cáo user:** đang play MAIN SESSION → double-click section item vào SECTION-TAB → âm MIDI item bị bypass (không qua mastering chain).
+- **Nguyên nhân (data thật — project "Section test" trong DB):** sub-track section (id TRÙNG main track id 1, 2) lưu `mastering_bypass=True` + `audio_bypass=True` (kế thừa từ track gốc). Mọi hàm quyết định bypass (`effMidiBypass`/`effAudioBypass`/`createMasteringRoute`/`routeBypassFor`/`getOrCreateSubTrackNode`) fallback `?? track.masteringBypass` → khi map chưa sync/thiếu entry (timing khi double-click + play lần đầu) → track MIDI-only bị tính bypass=TRUE → SF/sub-node route vào DRY bus (bypass mastering) dù ♪ tắt. Ngoài ra `handleEditSectionInTab` clone section tracks GIỮ NGUYÊN audioBypass/masteringBypass của track gốc → sync effect (14757) ghi map audio sai cho track section.
+- **FIX (app.jsx):**
+  (1) BỎ fallback `?? masteringBypass` khỏi mọi hàm quyết định route (effMidiBypass/effAudioBypass/createMasteringRoute/routeBypassFor/getOrCreateSubTrackNode) — nút A/♪ + `audioBypass`/`midiBypass` là nguồn duy nhất; `masteringBypass` không còn quyết định route (field legacy kế thừa sai).
+  (2) `handleEditSectionInTab` (16595) — clone section tracks ép reset bypass theo context: `masteringBypass:false, audioBypass:true (section raw default), midiBypass:false` — hết kế thừa flag track gốc.
