Vance Ingalls 04d12a134b refactor(studio): name the two branchy steps in the Audio FX panel
- 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.

@hyperframes/studio

Browser-based composition editor UI for Hyperframes. Provides a visual timeline, code editor, and live preview for building video compositions.

Install

npm install @hyperframes/studio

What it does

The studio is a React application with:

  • Visual timeline — drag, resize, and arrange elements on tracks
  • Code editor — edit HTML and GSAP scripts with CodeMirror (syntax highlighting, autocomplete)
  • Live preview — see changes in real time as you edit
  • Composition inspector — view and modify element properties

Development

The studio is embedded in the hyperframes preview command. To develop the studio UI itself:

cd packages/studio
bun run dev        # Start Vite dev server
bun run build      # Build for production
bun run typecheck  # Type-check

Tech stack

  • React 18/19, Zustand (state management)
  • CodeMirror 6 (editor)
  • Tailwind CSS (styling)
  • Vite (bundler)
