Editor close mid-drag now rolls back published contours like capture-loss does; bake detaches liveContours so a printed capture can't observe a live drag; a held note now receives a live publish that lands in the same block as a note-on; amp spline read clamped to [0,1].
Contours ride their own seqlock block into a double-buffered engine copy, and the swap step is smoothed. Each drag move publishes contours without a model write; release still commits and reloads.
The assert compiled out under Release's NDEBUG and ran in no test target.
AutomationChannel::release now requires a ReleaseProof that only
publishLiveParams() or noRepublishNeeded() can mint.
Points toPlain's exponent arm at the undetented curve map so host reads
match the editor; adds a sizeof guard plus field-poison test for
LiveValues::operator==; skips the model write when an automation value
hasn't moved; corrects five stale doc citations.
The SDK's own single-component sample drains inputParameterChanges in
process() and implements setParamNormalized; automation was reading the
GUI channel alone. The audio thread now patches a block it solely owns.
setInstrumentParams now arms a sticky pending restart that flushLatencyRestart drains from the sync tick; setState and the bake's adopt flush at their own tails.
Retire the effectiveGain blend so the meter's minimum tracks smoothGain's own
reduction against real input, unscaled by the transition mute — a toggle over
quiet material now reads no reduction instead of pinning to 0.
Fold setLimiterEnabled's restart request into setInstrumentParams so every writer
keeps the host's latency report in sync. Pin the window-sizing identity, drop the
per-sample modulo, tighten the ceiling tolerance, publish the blended gain.
Knob-drag publishes no longer block behind a full reload's WAV decode — a dedicated livePublishMutex_ replaces reloadMutex_ for the seqlock's single-writer contract. Also fixes an editor comment overclaim and two doc restatements.
