# HyperFrame Schema Compliance Review

## Executive Summary

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

## Critical Issues

None found. All compositions follow the core schema rules for determinism, finite timelines, and registration.

## Compliance Checklist

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

## File-by-File Analysis

### index.html

**Status**: COMPLIANT

- Correctly defines the master composition with `data-composition-id="master"`.
- Uses portrait dimensions (1080x1920).
- Loads sub-compositions using `data-composition-src`.
- Registers `master` timeline in `window.__timelines`.

### compositions/main-orchestration.html

**Status**: COMPLIANT

- Correctly uses `<template>` and `data-composition-id`.
- Registers `main-orchestration` timeline.
- Deterministic GSAP animations for background and video.
- Audio clips are correctly defined with `id`, `data-start`, and `data-track`.
- **Note**: Ensure audio files do not overlap on track 1 if their duration exceeds the gap between start times.

### compositions/captions.html

**Status**: COMPLIANT

- Correctly handles dynamic caption generation within a composition.
- Registers `captions` timeline.
- Uses deterministic logic for word animations based on a fixed transcript.
- Correctly uses `data-width` and `data-height`.

### compositions/graphics.html

**Status**: COMPLIANT

- Correctly uses `<template>` and `data-composition-id`.
- Registers `graphics` timeline.
- Uses deterministic pop-in and exit animations.
- Ambient motion is deterministic (uses fixed durations and repeats).
- Audio clips for SFX are correctly defined on track 10.
- **Note**: Ensure SFX audio files do not overlap on track 10 if their duration exceeds the gap between start times.
