+User-selected WAV originals are retained byte-for-byte here. Runtime files in music/ are 22050 Hz 16-bit stereo PCM WAV. Completion in audio/complete.wav is 22050 Hz mono, matching the existing SFX pool. Full durations and loop spans are retained. manifest.json records both source and runtime hashes. npm run build verifies runtime files rather than resynthesizing them; it needs no ffmpeg. To re-export a loop with ffmpeg: ffmpeg -i .audio-sources/play-a.wav -map_metadata -1 -fflags +bitexact -flags:a +bitexact -ar 22050 -ac 2 -c:a pcm_s16le music/play-a.wav .

+# 明亮教具室：正式循环编配 v1
+
+2026-10-23。保留已确认的音色与主题；本目录是独立音乐交付，不修改任何游戏版本。
+
+| 文件 | 用途 | 时长 | 速度与结构 |
+|---|---|---|---|
+| 01-menu-new-theme-loop-30s | 新菜单主题 | 30秒 | 96 BPM，12小节 |
+| 02-BGM-A-sunlit-classroom-loop | 原菜单主题改为关卡 A | 67.2秒 | 保持100 BPM，28小节 |
+| 03-BGM-B-soft-wood-loop | 保留木质关卡主题，淘汰原柔钢琴 A | 约65.455秒 | 保持88 BPM，24小节 |
+| 04-complete-retained-3s | 保留通关短句 | 3秒 | 与通过的 demo 字节一致，不循环 |
+
+两首关卡曲为保持原主题速度及完整乐句略超1分钟。不是简单复制30秒并淡入淡出：去除原示范的结束句，补齐完整和声周期；加入短句留白、轻微配器变化，末段属和声回到开头主和声。音符尾音与短房间反射循环跨接，无首尾淡入淡出或停顿。菜单采用新的旋律，仍沿用同一组柔和电琴、木琴和圆润低音音色。
+
+全部是固定混音，不做落格、节点或快速操作驱动的音量变化。编曲保持中低音域、短尾音与较少和声声部，为连线 SFX 留出空间。仍需实际游戏内试听决定统一静态 BGM 音量；本交付未进行游戏内叠加或手机听感验收。
+
+## 文件用途
+
+- WAV：44.1kHz / 16bit / 立体声，正式循环基准文件，循环区间为整文件。
+- OGG：三首循环曲的压缩版本，是否可用须由目标播放宿主确认。
+- MP3：便捷试听；不同播放器对编码延迟和填充处理不同，不承诺任意播放器原生整文件循环都无缝。开发时优先使用 WAV，或确认解码后长度与循环点的压缩格式。
+- arrangement-and-validation.json：完整事件、时长、帧数、峰值、RMS、边界相邻样本差。
+- build-loops.cjs / render.generated.cjs：可复现源文件。直接运行后者重制 WAV/MP3；完整构建脚本依赖相邻保留的 demo 源文件，另生成 OGG 和复制通关短句。
+
+循环检查涵盖PCM峰值、削波与跨边界连续性，不代表真实听音设备验收。通关MP3/WAV与此前版本完全一致。
+
+## 音源与署名
+
+旋律、编配、合成与渲染为本项目制作，非任天堂曲目改编。电琴、低音与节奏为程序合成；钢琴、木琴单音采样来自 tonejs-instruments，贡献者 N. P. Brosowsky，原始来源 Versilian Studios / VSCO 2，上游合集标注 CC BY 3.0。已进行移调、滤波、包络、声像和原创编配。正式上线保留署名与许可证信息，来源资料及本次所需采样已放入 sources/。

+✔ 手机没有浏览器音频接口时，原生播放器仍能播放全部 36 步和六类反馈音 (14.9009ms)
+✔ 关闭音效停止播放；再次开启会试听并保存偏好；后台中断停止所有播放器 (2.1632ms)
+✔ 延迟通关音在静音或进入后台时取消，不在返回后突然播放 (54.554ms)
+✔ 音频错误可诊断，不再静默吞掉 (1.5022ms)
+✔ 所有音频均为非静音 PCM；原版第13步比第1步高一个八度 (50.2806ms)
+✔ 教学和组合规则用具体动作及奇偶例子解释，没有未解释的术语 (34.0885ms)
+✔ 过关提示同步使用实际播放起点，非请求时间 (0.6778ms)
+✔ 过关短句使用用户提供的3秒WAV，不与旧和弦叠加 (2.7838ms)
+✔ merged irregular outlines retain holes and never draw internal unit edges (94.9455ms)
+✔ all 200 boards fit four screen budgets with stable safe anchors and real shared entrances (1024.4193ms)
+✔ guides through every irregular block stay inside its occupied shape (38.5314ms)
+✔ visited, conflicting and hinted category cells retain their material identity (13.3387ms)
+✔ five font subsets match their manifest and fit the package budget (4.7748ms)
+✔ upstream adapter fails closed if the inspected render seams change (1.1066ms)
+✔ procedural cushion pixels preserve holes and light the upper bevel without a border (23.2625ms)
+✔ visible glyph bounds are centered independently of font ascent and side bearings (2.0215ms)
+✔ stage with zero depth casts alpha shadows without painting a solid backing (11.0858ms)
+✔ native width-only TextMetrics still centers the rasterized glyph ink (3.2947ms)
+✔ fixed channels remain anchored at their block centers after number enlargement (1060.741ms)
+✔ checkpoint ribbons trigger on correct arrival only and never duplicate per frame (2.5724ms)
+✔ checkpoint pulse is small, centered in time and settles without looping (0.458ms)
+✔ event batches preserve every landing and sequence but commit only highest audio and haptic (6.5873ms)
+✔ completion waits at most 120ms and ignores late audio callbacks (1.2868ms)
+✔ light haptics are limited, checkpoint replaces light, and completion adds only one delayed short pulse (1.6916ms)
+✔ unsupported graded haptic falls back to one short pulse, never long vibration (1.0837ms)
+✔ haptic disable, preview and lifecycle cancellation suppress delayed or expired work (0.6282ms)
+✔ late failed haptic requests cannot revive old pulses and ungraded completion falls back once (0.38ms)
+✔ rectangles, concave shapes and hexagons require geometric inward distance without treating internal seams as walls (1.3569ms)
+✔ one high-speed native move records all intermediate cells and completion without duplicate final node (207.1856ms)
+✔ legal but off-solution moves use public rules, while invalid clues only produce error (148.4917ms)
+✔ drag near a previous-block boundary cannot undo; deeper entry can, and undo button remains immediate (86.424ms)
+✔ tutorial, redraw, hint and restored saved routes do not generate player feedback (134.7882ms)
+✔ pressure and rebound have bounded amplitude and duration (0.6392ms)
+✔ interpolation cannot duplicate the same failed-cell event within one native movement (0.5552ms)
+✔ nodes are driven by explicit events even when multiple arrive before rendering; at most two ribbons survive (46.156ms)
+✔ audio fast moves merge to latest pitch and completion stops the whole four-channel pool (3.0031ms)
+✔ settings persist haptic preference independently and chapter cards always use three columns (109.6829ms)
+✔ original audio is preserved and high pitches lose energy rather than growing sharper (17.1175ms)
+✔ empty, partial and wrong routes reveal the first incomplete full segment (5.642ms)
+✔ completion hides the hint; repeat clicks cannot skip; undo and restart return to earlier segments (9.2333ms)
+✔ all 200 levels reveal consecutive segments without changing the player path (2016.9027ms)
+✔ hint draws skip player edges and mask visited cells on their own layer; compositing is restored (1.5701ms)
+✔ parity is a segment anchor; colour is not; flow moves continuously across cells (0.6078ms)
+✔ coral teaching ribbon preserves visited masks and offers direction in reduced motion (2.9612ms)
+✔ hint rounds shared guide junctions and keeps separate runs disconnected (0.6602ms)

+✔ 200关的组合规则均能找到对应真实教学关 (147.2545ms)
+✔ 教学减速，结束停留1秒后自动循环 (3.0083ms)
+✔ music loops independently, persists mute and cancels in background (2.8131ms)
+✔ old arrows retain distance, rush to endpoint and fresh arrows move at base speed (0.9428ms)
+✔ settings have exactly three independent preferences, and hint has its own cue (238.1837ms)
+✔ actual fixed numeric node uses checkpoint pitch, final cell uses complete chord (167.2175ms)
+✔ selected menu and both level loops are stereo PCM WAV with complete musical durations (21.4585ms)
+✔ selected four runtime WAVs retain the original durations after sample-rate adaptation (40.46ms)
+✔ gameplay ambient uses lower scene volume and keeps independent mute and resume behavior (2.8611ms)
+✔ all 200 levels: valid numeric, parity and direction arrivals play checkpoint pitch; final arrival only completes (27899.3609ms)
+✔ drag back and undo button both vibrate lightly; disabling vibration suppresses both (58.2145ms)
+✔ haptic cadence is approximately 15 percent denser without changing light or medium grades (1.3006ms)
+✔ regular and special scale settle at 90ms with a larger special peak (0.4739ms)
+✔ rendered undo target and nonnumeric checkpoint animate immediately without adding ribbons (7.5203ms)
+✔ quick undo cancels removed node rebound, including last-step removal (2.1063ms)
+✔ first launch goes directly to gameplay (148.3509ms)
+✔ resume unfinished route after exit from gameplay (194.5898ms)
+✔ resume unfinished route after exit from selection (180.1794ms)
+✔ completed level resumes next unfinished, including leaving from cleared screen (120.5731ms)
+✔ replaying a cleared level does not replace the unfinished save (165.7154ms)
+✔ legacy saves, malformed data and full completion have valid startup targets (86.919ms)
+✔ selection pages expose fifteen cards and fit phone safe areas (337.4545ms)
+✔ hint-only frames reuse static UI, and player input invalidates it (59.5498ms)
+✔ hint curves are cached and distance lookup is stable at boundaries (0.9446ms)
+✔ new-mechanic lesson reuses the board while the continuous cursor advances (52.7928ms)
+✔ entering a level chooses either track once; redraw, mute and background resume keep that choice (2.0173ms)
+✔ subpackage completion never plays a stale scene after hiding, muting, or clearing (0.592ms)
+✔ music load failure is silent and one real resume can retry; muted pending loads stay silent (0.3667ms)
+✔ runtime uses supplied WAV hashes and ships music as a subpackage with a small main bundle (279.7373ms)
+✔ title is centered and selection settings share the progress and level-range row (294.8849ms)
+✔ completion pauses background loop, plays one selected jingle and the next level resumes a loop (172.4642ms)
+✔ title artwork is a transparent, high resolution PNG packaged locally (3.6602ms)
+✔ asynchronous native image load requests a repaint and draws the artwork without a font substitute (0.8729ms)
