HyperFrame Schema Compliance Review

Executive Summary

• Total files reviewed: 3
• Critical issues: 0
• Overall compliance status: PASS

Critical Issues

None. The compositions follow the deterministic requirements and essential timeline registration rules.

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 Reviews

index.html

Status: COMPLIANT

Observations:

• Correctly defines the root composition main-video.
• Uses data-width="1920" and data-height="1080" as requested for Landscape orientation.
• Properly registers window.__timelines["main-video"].
• Loads sub-compositions using data-composition-src.
• Primitive clips (video, audio) have required id, data-start, and data-track.
• Track assignments are clean: Track 0 (BG), Track 1 (Video), Track 2 (Graphics), Track 3 (Captions), Track 4 (Audio).

compositions/captions.html

Status: COMPLIANT

Observations:

• Uses <template> tag correctly.
• Root element has data-composition-id, data-width, data-height, and data-duration.
• Script is deterministic, using a fixed TRANSCRIPT array.
• Correctly registers window.__timelines["captions"].
• Note: The data-composition-id in the HTML is captions, and the script registers captions. In index.html, the container has data-composition-id="captions-comp". The framework typically matches the registration to the ID of the element being instantiated. Since the template root has data-composition-id="captions", this is the ID that should be registered.

compositions/graphics.html

Status: COMPLIANT

Observations:

• Uses <template> tag correctly.
• Root element has data-composition-id, data-width, data-height, and data-duration.
• Animations are deterministic GSAP tweens.
• Correctly registers window.__timelines["graphics-comp"].
• Layout is well-coordinated with the A-roll positioning defined in the master timeline.

Recommendations

• Consistency: In index.html, the captions container uses data-composition-id="captions-comp", but the template inside captions.html uses data-composition-id="captions". While the framework handles the swap during instantiation, keeping these IDs identical (e.g., both captions) improves maintainability.
• Deterministic Logic: The use of (function() { ... })() in sub-compositions is a good practice for scoping.
