From c89611f75f307140a167fc40a900af542133c110 Mon Sep 17 00:00:00 2001 From: Vance Ingalls Date: Thu, 16 Jul 2026 19:37:48 -0700 Subject: [PATCH] refactor(vst): split oversized files and dedupe CLI/engine code to clear fallow gate MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Splits propertyPanelVstSection.tsx (816->429 lines) into propertyPanelVstShared.ts, propertyPanelVstCarveSection.tsx, and propertyPanelVstPluginRows.tsx; useVstHost.ts (673->356 lines) into vstHostWire.ts (protocol parsing, pending-request bookkeeping, socket connect sequence); useVstPreview.ts (806->397 lines) into useVstPreviewHelpers.ts (load-scan orchestration, track lifecycle, PCM decode). Decomposes timelineIframeHelpers.ts's flagged autoHealMissingCompositionIds and buildMissingCompositionElements. Dedupes parseIntFlag/parsePositiveInt/parseEnum and the sites-create verb guard shared by lambda.ts/cloudrun.ts into utils/distributedRenderFlags.ts, and the ffmpeg-timeout/output-dir/ result-building boilerplate shared by audioMixer.ts's extract/prepare/ silence helpers. Extracts shared test-render boilerplate (testRenderUtils.tsx) across the propertyPanelFlat*.test.tsx family and per-file test fixtures (vstSidecarTestFixture.ts, vstSocketTestFixture.ts) elsewhere. Also fixes two 600-line filesize-gate regressions introduced while reconciling this work against an updated origin/main: extracts removeBackgroundViaApi out of StudioRightPanel.tsx, and drops a dead re-export block from PropertyPanel.tsx (its only consumer already had the real source available directly). All of the above is pure extraction/dedup — no behavior change. Verified: fallow audit passes clean (0 introduced complexity/duplication/dead-code findings), full monorepo build succeeds, and the full test suite passes across studio/engine/cli/vst-host.

(Per an earlier controller decision noted in the task brief, `resolveWavPath` was intentionally NOT added — the `/vst/carve` route resolves project-relative paths server-side, so no client-side wav-path round trip is needed.) +- Added `fetchCarveBands(projectId, musicPath, voicePath, maxCutDb)` — a small module-scope helper that POSTs to `/api/vst/carve` and validates the response shape, returning `CarveBand[] | null`. This was extracted out of `handleCarve` specifically to keep that handler's own cyclomatic complexity down (see "Concerns" below) — it's my own contribution being simplified, not a change to pre-existing code. +- Added component state (declared before the `if (!vstHost) return` early-return guard, to respect the Rules of Hooks): `elements` (via `usePlayerStore((s) => s.elements)`), `carveOpen`, `carveAmount`, `carveVoId` (with a `useEffect` keeping the selection valid as tracks change), and the derived `voCandidates` (other audio tracks, excluding the current track, requiring a `src`) / `defaultVoId` (first `timelineRole === "voiceover"` candidate, else the first candidate). +- Added `handleCarve` (a plain async function, defined alongside the other handlers after the early-return, since it isn't itself a hook): resolves both tracks' `src` to project-relative sub-paths via `projectRelativeAssetPath`, calls `fetchCarveBands`, reads the existing chain via `readChainFile`, appends bands via `appendCarveBands`, writes via `writeChainFile`, stamps `domEditSaveTimestampRef`, calls `onSetAttribute("vst-chain", path)`, and bumps `usePlayerStore.getState().bumpVstChainRevision()`. +- Added the render block: a "Make room for voiceover" button (`data-vst-carve-open`) that reveals a VO-track `` (`data-vst-carve-amount`), and Apply (`data-vst-carve-apply`) / Cancel buttons. Only rendered when `voCandidates.length > 0`. + +In `packages/studio/src/components/editor/propertyPanelVstSection.test.tsx`: + +- Added a new `describe("VstSection — make room for voiceover", ...)` block with one test, adapted to this file's actual query style (`renderInto`/`act`/`host.querySelector`/`flushAsyncWork`/`makeAudioElement`/`makeVstHost`/`jsonResponse`/`requestUrl` — the file does NOT use `@testing-library/react`'s `render`/`screen`/`fireEvent`/`waitFor` as the brief's literal snippet assumed).
