-# Verdict: add-decomposition-content
-
-## Status: PASS
-**Completion Date**: 2026-06-14
-
-## Summary
-Added decomposition_content, parent_spec_content, vram_config_content fields to Task model. Added WaveGroup dataclass and parse_waves() function for structured wave extraction from DECOMPOSITION.md. Dashboard JS wave stats now use parsed wave data instead of 50/50 heuristic. Detail panel shows new content sections for decomposition, parent context, and VRAM config.
-
-## Findings
-- All 134 tests pass (8 new)
-- parse_waves correctly handles both `(label)` and `: label` wave header formats
-- Falls back to 50/50 heuristic in JS when no wave data available
-- Task model is backward compatible (new fields default to None)
