+### Live spline-envelope drags: held and new notes follow a dragged knot
+
+Dragging a knot on a Spline-mode amp/pitch/filter envelope in ReaSampler 9000's editor
+is now audible during the drag, for both held and new notes — releasing still commits
+exactly as before, in one undo point. The three contours travel to the audio thread on
+their own seqlock-published, double-buffered block (`core/instrument/engine/live_contours.h`,
+`seqlock.h`), separate from `LiveValues` so a knob publish, an automation merge or the
+live-block compare never carry the ~9 KB contour payload. Landed in the same merge:
+closing the editor mid-drag rolls the published contours back to the pre-grab snapshot
+(`removedFromParent`); the resample bake detaches live contours before its own render
+(`bake_render.cpp`); a pre-existing bug is fixed where a live-parameter publish arriving
+in the same block as a note-on failed to reach the already-held, sounding voices —
+`startVoice`'s `refreshLive()` consumed the new generation without applying it to active
+voices (`VoiceEngine::startVoice` now calls `applyLiveToActive()`); and the amp spline's read is
+clamped to `[0,1]` to absorb a swap-step overshoot from the smoother. Not DAW-verified —
+checks are tracked in `docs/SEPT_VERIFY.md` §5.
