# T01: Created composition prompt with merge rules, citation re-indexing, deduplication guidance, and two valid v2 JSON examples

**Created composition prompt with merge rules, citation re-indexing, deduplication guidance, and two valid v2 JSON examples**

## What Happened

Wrote prompts/stage5_compose.txt — the LLM prompt for composing new video moments into an existing technique page. Defines four XML input tags, offset-based citation re-indexing (existing [0]-[N-1], new [N]-[N+M-1]), detailed merge/enrich/dedup rules with concrete examples, workflow-ordered section placement, and v2 SynthesisResult output format. Two JSON examples included, both validated structurally.

## Verification

Ran structural validation: file exists, 13053 chars (>2000), all 7 required sections present, both JSON blocks parse and validate with correct v2 structure (pages key, body_sections_format, moment_indices).

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `python3 structural validation (sections + JSON parse)` | 0 | ✅ pass | 300ms |
| 2 | `python3 dual JSON block validation (v2 schema)` | 0 | ✅ pass | 200ms |
