- audioFxSummary (14 cyclomatic / 19 cognitive) counted enabled nodes inline while also deciding what to say about them. countEnabledNodes now owns the parse and the split, and returns null for an unreadable chain, so the summary reads as the four sentences it produces. - The reveal effect's five-way nested ternary for "which row does this parameter live in" is now revealRowSelector, and the resolve-query-scroll sequence around it is scrollRevealedRowIntoView. Both live in audioFxRevealTarget.ts beside the resolver whose output they consume, which also brought propertyPanelFxSection.tsx from 616 to 598 lines -- under the 600 cap for the first time, so this commit needs no --no-verify. With these cleared the fallow audit gate passes (exit 0). Two notes for whoever touches this next: - fallow fingerprints a finding by line position, so inserting a helper ABOVE a complex function re-flags that function's inherited complexity as new. Adding revealRowSelector above FxSection re-flagged FxSection's own 22/32; moving it out fixed both. - A helper extracted only to satisfy the gate has to stay used from one place, or it lands as an unused export instead. studio's editor suite (102 files, 1269 tests) passes unchanged.
