+版本：2026-10-23-warm-ambient-bgm。用户选择试用温暖、无节拍、弱旋律方向；本轮仅替换关卡音乐，选关音乐保持原文件哈希。
+
+- 原创32秒循环：低中音区柔和和声缓慢交叠，没有鼓点、规律敲击或突出旋律；采用周期波形与平滑交叉渐变，避免循环接缝。
+- PCM均方根约0.035，峰值小于0.17，关卡播放音量0.14；选关音量仍为0.16。保留音乐／音效／振动独立开关及后台、中断恢复。
+- 节点确认音、通关和弦、缩放、触觉、存档、选关标题及200关规则保留。之前节点跟手与立体标题发布包保留。
+- 验收：80项模块测试、200关触摸回归；生成资源的接缝、包络突变、音量及开关恢复检查。实际听感与真机扬声器／耳机效果需用户试听。

+✔ all 200 boards fit four screen budgets with stable safe anchors and real shared entrances (570.0971ms)
+✔ guides through every irregular block stay inside its occupied shape (30.9901ms)
+✔ visited, conflicting and hinted category cells retain their material identity (7.9789ms)
+✔ five font subsets match their manifest and fit the package budget (3.2457ms)
+✔ upstream adapter fails closed if the inspected render seams change (0.7175ms)
+✔ procedural cushion pixels preserve holes and light the upper bevel without a border (15.739ms)
+✔ visible glyph bounds are centered independently of font ascent and side bearings (1.4517ms)
+✔ stage with zero depth casts alpha shadows without painting a solid backing (6.6306ms)
+✔ native width-only TextMetrics still centers the rasterized glyph ink (2.1955ms)
+✔ fixed channels remain anchored at their block centers after number enlargement (780.5029ms)
+✔ checkpoint ribbons trigger on correct arrival only and never duplicate per frame (2.334ms)
+✔ checkpoint pulse is small, centered in time and settles without looping (0.2499ms)
+✔ event batches preserve every landing and sequence but commit only highest audio and haptic (3.9613ms)
+✔ completion waits at most 120ms and ignores late audio callbacks (0.818ms)
+✔ light haptics are limited, checkpoint replaces light, and completion adds only one delayed short pulse (0.7328ms)
+✔ unsupported graded haptic falls back to one short pulse, never long vibration (0.5939ms)
+✔ haptic disable, preview and lifecycle cancellation suppress delayed or expired work (0.5278ms)
+✔ late failed haptic requests cannot revive old pulses and ungraded completion falls back once (0.359ms)
+✔ rectangles, concave shapes and hexagons require geometric inward distance without treating internal seams as walls (1.3903ms)
+✔ one high-speed native move records all intermediate cells and completion without duplicate final node (125.9551ms)
+✔ legal but off-solution moves use public rules, while invalid clues only produce error (65.1831ms)
+✔ drag near a previous-block boundary cannot undo; deeper entry can, and undo button remains immediate (47.9813ms)
+✔ tutorial, redraw, hint and restored saved routes do not generate player feedback (71.153ms)
+✔ pressure and rebound have bounded amplitude and duration (0.3831ms)
+✔ interpolation cannot duplicate the same failed-cell event within one native movement (0.4001ms)
+✔ nodes are driven by explicit events even when multiple arrive before rendering; at most two ribbons survive (24.6483ms)
+✔ audio fast moves merge to latest pitch and completion stops the whole four-channel pool (1.6418ms)
+✔ settings persist haptic preference independently and chapter cards always use three columns (67.065ms)
+✔ original audio is preserved and high pitches lose energy rather than growing sharper (9.7041ms)
+✔ empty, partial and wrong routes reveal the first incomplete full segment (2.5105ms)
+✔ completion hides the hint; repeat clicks cannot skip; undo and restart return to earlier segments (0.6003ms)
+✔ all 200 levels reveal consecutive segments without changing the player path (1327.0448ms)
+✔ hint draws skip player edges and mask visited cells on their own layer; compositing is restored (0.7515ms)
+✔ parity is a segment anchor; colour is not; flow moves continuously across cells (0.3026ms)
+✔ coral teaching ribbon preserves visited masks and offers direction in reduced motion (1.3771ms)
