The calibration contract deferred this until the stability check came back dirty. It did: the first fleet read found 304 installs (1.08%) reporting both values for a canary whose percentage never moved, and the genuinely anomalous ones could not be separated from a developer toggling HF_CANARY_*, because the assignment alone is identical in both cases. resolveCanary has always computed the reason and canaryEventProperties dropped it. Now every canary emits canary_reason_<name> beside its assignment. Deliberately outside the $feature/ namespace: PostHog treats those as flag values, and a non-boolean there would corrupt the flag's own breakdowns. Two of the six wire values are immediately useful beyond override attribution. 'excluded' identifies CI installs, which today have to be dropped by joining on is_ci — conflating them with out_of_cohort is what made the first accuracy read look like a significant failure (9.22% against a 10% target) when it was not. 'no_unit_id' surfaces the fails-closed corner. The reason is optional on the core helper so existing callers are unaffected. 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 }[]
