HyperFrame Schema Compliance Review

Executive Summary

• Total files reviewed: 4
• Critical issues: 0
• Overall compliance status: PASS

Critical Issues

None found. The compositions follow the HyperFrame schema correctly, including deterministic code, finite timelines, and proper registration.

Compliance Checklist

• All compositions have data-width and data-height attributes
• All timelines are finite with duration > 0
• All compositions registered in window.__timelines
• No use of Math.random(), Date.now(), or non-deterministic code
• Primitive clips have required data attributes (id, data-start, data-track)
• data-duration specified for all <img> clips (N/A - no images used)
• No manual media playback control (video.play(), audio.pause(), etc.)
• No manual clip mounting/unmounting in scripts
• Relative timing references are valid (N/A - absolute timing used)
• Clips on same track don't overlap in time
• Reusable compositions in separate HTML files
• Composition files use <template> tags
• External compositions loaded via data-composition-src
• All script-animated content wrapped in compositions
• No infinite or zero-duration timelines

File Analysis

index.html

Status: COMPLIANT

Observations:

• Correctly defines the master composition with data-composition-id="editor-agent".
• Includes data-width, data-height, and data-duration.
• Orchestrates sub-compositions using data-composition-src.
• Registers the master timeline in window.__timelines.

compositions/title-card.html

Status: COMPLIANT

Observations:

• Uses <template> tag as required.
• Root element has data-composition-id, data-width, data-height, and data-duration.
• Script is deterministic and registers the timeline correctly.
• Styles are scoped using the [data-composition-id="title-card"] selector.

compositions/captions.html

Status: COMPLIANT

Observations:

• Uses <template> tag.
• Root element has all required data attributes.
• Script uses a deterministic array of timings for caption animations.
• Correctly registers the timeline.

compositions/main-video.html

Status: COMPLIANT

Observations:

• Uses <template> tag.
• Root element has all required data attributes.
• Contains a primitive <video> clip with id, data-start, data-duration, and data-track.
• Script handles visual animations (scaling, positioning, opacity) without interfering with video playback.
• Background animations are deterministic (fixed durations and values).
• Correctly registers the timeline.

Recommendations

• Relative Timing: While absolute timing is used correctly, consider using relative timing (e.g., data-start="title-card") in index.html for better maintainability if durations change.
• Asset Paths: Ensure all asset paths (like assets/abstract_shapes.svg) are correct relative to the final deployment structure.
