+✔ 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 (4.1103ms)
+✔ 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 (0.7541ms)

+✔ 音频错误可诊断，不再静默吞掉 (0.4347ms)
+✔ 所有音频均为非静音 PCM；原版第13步比第1步高一个八度 (19.472ms)

+✔ 过关提示同步使用实际播放起点，非请求时间 (0.598ms)
+✔ 过关和弦收尾持续衰减，不在后半段重新起音 (2.2637ms)
+✔ merged irregular outlines retain holes and never draw internal unit edges (47.6935ms)
+✔ all 200 boards fit four screen budgets with stable safe anchors and real shared entrances (522.3449ms)
+✔ guides through every irregular block stay inside its occupied shape (25.4141ms)
+✔ visited, conflicting and hinted category cells retain their material identity (10.5537ms)
+✔ five font subsets match their manifest and fit the package budget (3.8279ms)
+✔ upstream adapter fails closed if the inspected render seams change (0.6365ms)
+✔ procedural cushion pixels preserve holes and light the upper bevel without a border (19.9765ms)
+✔ visible glyph bounds are centered independently of font ascent and side bearings (1.1753ms)
+✔ stage with zero depth casts alpha shadows without painting a solid backing (5.6615ms)
+✔ native width-only TextMetrics still centers the rasterized glyph ink (1.7123ms)
+✔ fixed channels remain anchored at their block centers after number enlargement (737.8066ms)
+✔ checkpoint ribbons trigger on correct arrival only and never duplicate per frame (2.4057ms)
+✔ checkpoint pulse is small, centered in time and settles without looping (0.2773ms)
+✔ event batches preserve every landing and sequence but commit only highest audio and haptic (2.5258ms)
+✔ completion waits at most 120ms and ignores late audio callbacks (0.502ms)
+✔ light haptics are limited, checkpoint replaces light, and completion adds only one delayed short pulse (0.6548ms)
+✔ unsupported graded haptic falls back to one short pulse, never long vibration (0.5295ms)
+✔ haptic disable, preview and lifecycle cancellation suppress delayed or expired work (0.4659ms)
+✔ late failed haptic requests cannot revive old pulses and ungraded completion falls back once (0.2774ms)
+✔ rectangles, concave shapes and hexagons require geometric inward distance without treating internal seams as walls (1.2234ms)
+✔ one high-speed native move records all intermediate cells and completion without duplicate final node (101.4652ms)
+✔ legal but off-solution moves use public rules, while invalid clues only produce error (60.733ms)
+✔ drag near a previous-block boundary cannot undo; deeper entry can, and undo button remains immediate (50.3433ms)
+✔ tutorial, redraw, hint and restored saved routes do not generate player feedback (73.5198ms)
+✔ pressure and rebound have bounded amplitude and duration (0.3127ms)
+✔ interpolation cannot duplicate the same failed-cell event within one native movement (0.2822ms)
+✔ nodes are driven by explicit events even when multiple arrive before rendering; at most two ribbons survive (15.717ms)
+✔ audio fast moves merge to latest pitch and completion stops the whole four-channel pool (1.2373ms)
+✔ settings persist haptic preference independently and chapter cards always use three columns (65.661ms)
+✔ original audio is preserved and high pitches lose energy rather than growing sharper (6.1515ms)
+✔ empty, partial and wrong routes reveal the first incomplete full segment (2.0087ms)
+✔ completion hides the hint; repeat clicks cannot skip; undo and restart return to earlier segments (0.3693ms)
+✔ all 200 levels reveal consecutive segments without changing the player path (1237.8614ms)
+✔ hint draws skip player edges and mask visited cells on their own layer; compositing is restored (0.9316ms)
+✔ parity is a segment anchor; colour is not; flow moves continuously across cells (0.3255ms)
+✔ coral teaching ribbon preserves visited masks and offers direction in reduced motion (1.484ms)
+✔ hint rounds shared guide junctions and keeps separate runs disconnected (0.3731ms)

+✔ music loops independently, persists mute and cancels in background (2.2845ms)
+✔ old arrows retain distance, rush to endpoint and fresh arrows move at base speed (0.8258ms)
+✔ settings have exactly three independent preferences, and hint has its own cue (104.2538ms)
+✔ actual fixed numeric node uses checkpoint pitch, final cell uses complete chord (95.8327ms)
