✔ 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)

✔ 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)
