# Add Decomposition Content to Dashboard Data Model
## Goal
Add missing content fields to the `Task` model so the dashboard can display wave structure from `DECOMPOSITION.md`, parent task context from `PARENT_SPEC.md`, and VRAM constraints from `VRAM_CONFIG.md`.
## Requirements
### R1. Add `decomposition_content` to Task model
`automaton/dashboard/core/task.py`: The `Task` dataclass has six content fields (`spec_content`, `verdict_content`, `bug_report_content`, `adversarial_bug_report_content`, `doc_review_content`, `design_content`) but no `decomposition_content`. This is the root cause of the dashboard's inability to parse wave structure from `DECOMPOSITION.md`.
**Fix**:
- Add `decomposition_content: Optional[str] = None` field to the `Task` dataclass (`task.py:77-90`)
- In `discover_tasks()` (`task.py:243-286`), load `DECOMPOSITION.md` content similar to how other artifacts are loaded
- Add `"decomposition_content"` to the `/api/tasks` response in `ui/app.py` `_serve_tasks()` and `_serve_task()`
### R2. Parse wave structure from DECOMPOSITION.md content
Currently `dashboard.js:278-285` splits sub-tasks into waves using a 50/50 heuristic (`half = Math.ceil(task.sub_tasks.length / 2)`), completely ignoring the actual wave definitions in `DECOMPOSITION.md`.
**Fix**:
- Parse wave headers from `decomposition_content` (Python side): extract `### Wave 1:` and `### Wave 2:` sections and their sub-task lists
- Store parsed wave data as `waves: list[WaveGroup]` on the `Task` model or as structured data in the API response
- Each wave group contains: wave number, label, sub-task names
- In `dashboard.js`, use parsed wave data instead of 50/50 heuristic for wave statistics
- Fall back to 50/50 heuristic only when `decomposition_content` is unavailable
### R3. Add `parent_spec_content` and `vram_config_content` to Task model
Sub-tasks have `PARENT_SPEC.md` and `VRAM_CONFIG.md` but these are not in the `ARTIFACTS` dict and not visible in the API response or detail panel. The detail panel cannot show parent context or VRAM constraints.
**Fix**:
- Add `parent_spec_content: Optional[str] = None` and `vram_config_content: Optional[str] = None` to `Task`
- Load these in `discover_tasks()` if the files exist
- Include in the API response
- Display in the detail panel when present (e.g., "Parent Context" and "VRAM Configuration" sections)
### R4. Add `WaveGroup` dataclass
Add a simple dataclass for wave metadata:
```python
@dataclass
class WaveGroup:
wave_number: int
label: str
sub_task_names: list[str]
```
### R5. Parse DECOMPOSITION.md wave sections
Add a `parse_waves(content: str) -> list[WaveGroup]` function that extracts wave definitions from `DECOMPOSITION.md` content. Pattern: `### Wave N: label` followed by lines starting with `- subtask-name`.
## Acceptance Criteria
- [ ] `Task` model has `decomposition_content`, `parent_spec_content`, `vram_config_content` fields
- [ ] `/api/tasks` response includes `decomposition_content` when present
- [ ] `/api/tasks` response includes `parent_spec_content` and `vram_config_content` when present
- [ ] `parse_waves()` correctly extracts wave structure from the template `DECOMPOSITION.md` in `templates/tasks/subtask-parent/`
- [ ] Dashboard JS uses parsed wave data for Wave 1/Wave 2 statistics instead of 50/50 split
- [ ] Detail panel shows "Parent Context" section when `parent_spec_content` exists
- [ ] Detail panel shows "VRAM Configuration" section when `vram_config_content` exists
- [ ] Existing tests pass
- [ ] New test: `parse_waves` with real DECOMPOSITION.md content
- [ ] New test: task with PARENT_SPEC.md and VRAM_CONFIG.md has content fields populated
## Non-Goals
- Not changing the DECOMPOSITION.md format
- Not applying VRAM constraints — display only
- Not modifying how sub-tasks are created or executed
