# TODO

## Repo bootstrap
- [x] Define project direction and constraints in `agents.md`
- [x] Add `requirements.txt` (pip dependencies)
- [x] Add `environment.yml` (conda environment; PyTorch CUDA 12.x runtime strategy)
- [x] Add storyboard JSON template at `templates/storyboard.template.json`

## Core implementation (next)
- [x] Create repo structure: `src/`, `tests/`, `docs/`, `templates/`, `outputs/`
- [x] Implement storyboard schema validator (pydantic) + loader
- [x] Implement prompt compiler (global style + shot + camera)
- [x] Implement shot planning (duration -> frame count, chunk plan)
- [x] Implement model backend interface (`BaseVideoBackend`)
- [x] Implement WAN backend (primary) with VRAM-safe defaults
- [ ] Implement fallback backend (SVD) for reliability testing
- [x] Implement ffmpeg assembler (concat + optional audio + debug burn-in)
- [ ] Implement optional upscaling module (post-process)

## Utilities
- [ ] Write storyboard "plain text -> JSON" utility script (fills `storyboard.template.json`)
- [x] Add config file support (YAML/JSON) for global defaults

## Testing (parallel work; required)
- [x] Add `pytest` scaffolding
- [x] Add tests for schema validation
- [x] Add tests for prompt compilation determinism
- [x] Add tests for shot planning (frames/chunks)
- [x] Add tests for ffmpeg command generation (no actual render needed)
- [x] Ensure every code change includes a corresponding test update

## Documentation (maintained continuously)
- [ ] Create `docs/developer.md` (install, architecture, tests, adding backends)
- [ ] Create `docs/user.md` (quickstart, storyboard creation, running, outputs, troubleshooting)
- [ ] Keep docs updated whenever CLI/config/schema changes

## Current Status
- **Completed:** 12/19 tasks
- **In Progress:** FFmpeg assembler implementation
- **Next:** CLI entry point, Documentation

## Recent Updates
- Fixed environment.yml for PyTorch 2.5.1 compatibility
- Implemented WAN backend with lazy imports
- Created FFmpeg assembler module
- All core tests passing (29 tests)
