+### [2026-08-03] Task: Fix Wave Observer trong FX Rack không hiển thị Audioclip/Section item
+- **Tóm tắt thay đổi:** `__getTrackScopeAnalysers` ưu tiên `sfAnalyser` (chỉ tiếng MIDI) khi track có midiItems → scope chỉ hiển thị MIDI, audioclip/section không xuất hiện. FIX: (1) nối thêm `sfOut → scopeSplitter` (cùng splitter với pannerNode) → scopeAnalyserL/R giờ trộn TÍN HIỆU ĐẦY ĐỦ post-FX của track: audioclip + section (pannerNode) + midi (sfOut); (2) bỏ nhánh ưu tiên sfAnalyser trong `__getTrackScopeAnalysers` (luôn dùng scopeAnalyserL/R đã trộn).
+- **Các file ảnh hưởng:** `app/static/js/app.jsx`, `app/static/js/app.precompiled.js` (rebuild), `app/templates/index.html` (bump v=202608034700)

+- **Tóm tắt thay đổi:** Theo yêu cầu bắt buộc của user: **PWR sáng (ON) = mọi items (MIDI/section/audioclip) qua FX Rack Panel**; **A và ♪ chỉ dùng với Mastering FX Chain** (không ảnh hưởng track FX):
+  1. **Audio path**: dryGain của route chuyển từ tap PRE-FX (gainNode) sang **POST-FX (analyserNode)** — A bypass giờ chỉ bỏ mastering; track FX Rack (fxEntry → modules) vẫn áp dụng cho clip/section bất kể A.
+  2. **MIDI path**: thêm route riêng `sfRouteGain`/`sfDryGain` (sfPan → cả 2; sfRouteGain → masterBus.input, sfDryGain → masterBus.dryInput) — ♪ bypass chỉ bỏ mastering; SF vẫn qua sfModules (track FX, PWR-controlled). `__setTrackBypass('midi')` toggle trực tiếp route này; `updateSfRouting` bỏ nhánh dryInput (SF LUÔN vào sfEntry); effect sync áp lại khi load/undo.
+  3. Tooltip cả 2 strip cập nhật: "A/♪ = Mastering FX Chain... XÁM = bypass mastering (vẫn qua track FX Rack)".

+- **Tóm tắt thay đổi:** User báo: FX Rack ON chỉ MIDI được xử lí, audioclip/section không. **NGUYÊN NHÂN THẬT**: `startLocalTrackPlayback` (loop selection) có dòng cũ `gainNode.connect(pannerNode)` — connect THẲNG gainNode → pannerNode, BỎ QUA fxEntry → [FX modules] → fxLegacyIn. Node track được CACHE → mọi playback sau (kể cả play thường) giữ đường thẳng này → clip vào panner 2 lần (1 qua FX + 1 thẳng) → FX bị pha loãng/không nghe rõ. FIX: bỏ dòng đó (node đã tự wire đúng). Lưu ý thứ 2 cho user: nếu nút A (bypass audio) đang XÁM, clip/section đi thẳng (dry — bỏ FX + mastering) theo thiết kế — MIDI vẫn qua FX (đường SF riêng) → muốn clip qua FX phải tắt nút A (sáng xanh).

+- **Tóm tắt thay đổi:** Nút PWR trước đây chỉ toggle state local UI (không tác dụng DSP). Giờ thành state THẬT trên track (`fxActive`, serialize `fx_active`, default true):
+  1. **getOrCreateTrackNode**: `fxEnabled = track.fxActive !== false` gate cả 3 nhánh — audio fxChain modules, chorus/reverb legacy, SF chain modules (MIDI) — khi OFF: gainNode → fxLegacyIn → panner (không module nào), SF → sfEntry → thẳng sfOut.
+  2. **rebuildTrackFxGraph**: gate cả 2 chain (audio + SF) — bấm PWR khi đang play re-route ngay.
+  3. **Nút PWR (TrackStripConsole)**: toggle `track.fxActive` + `__rebuildTrackFxGraph` — sáng = ON (mọi items qua FX Rack Panel), tối = OFF (bỏ FX). Bỏ state local isFxActive.
+  4. Track mới default `fxActive: true`; deserialize cũ → true (không phá project cũ).

 - **Tóm tắt thay đổi:** User (bundle mới nhất, log route ĐÚNG: track1 bypass routeGain=0/dryGain=1) vẫn nghe audioclip qua mastering + tăng gain quá mức. **NGUYÊN NHÂN THẬT**: patch "SF path độc lập" trước đó nối `gainNode.connect(sfEntry)` VĨNH VIỄN — clip audio ở gainNode chảy luôn vào đường SF (`sfEntry → sfModules → sfOut → sfPan → masterBus.input → mastering`) → clip nghe **2 đường cùng lúc** (dry + SF path qua mastering) dù bypass bật → tăng gain + vẫn bị mastering xử lý. FIX:
   1. **XÓA `gainNode.connect(sfEntry)`** — SF output vào sfEntry TRỰC TIẾP qua `setOutputDestination(sfEntry)` (updateSfRouting), không đi qua gainNode → clip không bao giờ chảy vào SF chain.
   2. **sfEntry.gain mirror audible gain** (volume/mute/solo) ở 3 nơi: getOrCreateTrackNode (khởi tạo), applyAllTrackMuteSolo, effect sync `[tracks, sessionTabs]` — SF vẫn tuân theo fader/mute/solo.
