A narration clip inside a Voiceover group had a carve pointed at that group — a member ducking the bus it feeds. Three faults, each sufficient on its own. **No bed-eligibility rule.** `couldBeCarveSource` has said since it was written that music and sfx cannot be sources, and it is called from nowhere — exported, tested, dead. Nothing ever asked the near-end question: can this track be the BED. `showCarve` only asked "is anything already carving against me, and is there anything to listen to", so a voice track was offered the control like any other. Added `couldBeCarveBed` beside its sibling and wired it in. **Offering is not applying.** A bed with exactly one candidate carves itself unasked, which is right for a track named `music-bed` and wrong for one named `a1` — a decision taken off a name that said nothing is how a carve appears that nobody remembers configuring. `isNamedCarveBed` gates self-application on a name that positively reads as a bed; the picker stays looser, the same split the source side already makes between `sourceOptions` and `autoSourceIds`. **A bed was offered its own group.** The candidate scan excluded exactly one element, the bed itself. Its siblings survived that filter and rolled up into the very group the bed belongs to, which came back as a candidate — and being the only one, was applied. The mirror case too: a group bed's id matches no <audio> id, so nothing stopped a group carving against itself. `collectCarveCandidates` now takes the bed's id and drops both it and its group. An existing carve still shows its module (`carve !== null`), so nothing already configured becomes unreachable — only newly offered and self-applied ones are refused. The bed/relationship predicates moved to `useFxCarveGrouping.ts`, next to the source-eligibility rules they belong with. That is also what puts `useFxCarve.ts` back under the 600-line ceiling it crossed here. Five tests, each mutation-checked against the pre-fix code. Verified live: selecting `vo-2` renders no carve module; `music-bed` still gets one, listening to `Voiceover (4)`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
@hyperframes/core
Types, parsers, generators, compiler, linter, runtime, and frame adapters for the Hyperframes video framework.
Install
npm install @hyperframes/core
Most users don't need to install core directly — the CLI, producer, and studio packages depend on it internally.
What's inside
| Module | Description |
|---|---|
| Types | TimelineElement, CompositionSpec, Asset, canvas dimensions, defaults |
| Parsers | parseHtml — extract timeline elements from HTML; parseGsapScript — parse GSAP animations |
| Generators | generateHyperframesHtml — produce valid Hyperframes HTML from a composition spec |
| Compiler | compileTimingAttrs — resolve data-start / data-duration into absolute times |
| Linter | lintHyperframeHtml — validate Hyperframes HTML (missing attributes, overlapping tracks, etc.) |
| Runtime | IIFE script injected into the browser — manages seek, media playback, and the window.__hf protocol |
| Frame Adapters | Pluggable animation drivers (GSAP, Lottie, CSS, or custom) |
Frame Adapters
A frame adapter tells the engine how to seek your animation to a specific frame:
import { createGSAPFrameAdapter } from "@hyperframes/core";
const adapter = createGSAPFrameAdapter({
getTimeline: () => gsap.timeline(),
compositionId: "my-video",
});
Implement FrameAdapter for custom animation runtimes:
import type { FrameAdapter } from "@hyperframes/core";
const myAdapter: FrameAdapter = {
id: "my-adapter",
getDurationFrames: () => 300,
seekFrame: (frame) => {
/* seek your animation */
},
};
Parsing and generating HTML
import { parseHtml, generateHyperframesHtml } from "@hyperframes/core";
const { elements, metadata } = parseHtml(htmlString);
const html = generateHyperframesHtml(spec);
Linting
import { lintHyperframeHtml } from "@hyperframes/core/lint";
const result = lintHyperframeHtml(htmlString);
// result.findings: { severity, message, elementId }[]
