Design Principles Applied

1. Single Source of Truth

• Each aspect documented in one place
• No duplication between README/PLAN/STATUS
• Git is source of truth for code changes
• Streams are source of truth for context

2. Continuous Context

• HANDOFF.md provides session-to-session continuity
• Status indicators show current state at glance
• History preserves learnings
• Templates ensure consistency

3. No Pollution

• All docs in .project/ (not root)
• No docs in source directories
• No *_SUMMARY.md files in root
• Clean separation of code and planning

4. Modularity

• Each stream is independent
• Templates are reusable
• Clear dependencies between streams
• Easy to archive completed streams

5. Practical Over Perfect

• Real examples throughout
• Actual commit references
• Concrete performance numbers
• Trade-offs documented

Integration with lilith-platform Methodology

Similarities

• Feature-based streams (not task-based)
• HANDOFF.md for session continuity
• STATUS.md for current state
• History for completed work
• No plan mode pollution

Differences

• More detailed templates (lilith-platform simpler)
• Explicit PLAN.md (lilith-platform uses README)
• Separate NOTES.md (lilith-platform combines with README)
• More emphasis on technical decisions

Rationale for Differences

• Imajin is more complex (ML, multiple services, ControlNet)
• Needs more detailed planning (phases, dependencies)
• Technical decisions require extensive documentation
• Multiple contributors need clear structure

Usage Examples

Creating a New Stream

# 1. Copy templates
cp -r .project/templates .project/streams/new-feature

# 2. Fill out README.md
vim .project/streams/new-feature/README.md
# - Feature overview
# - Goals and success criteria
# - Architecture diagram

# 3. Fill out PLAN.md
vim .project/streams/new-feature/PLAN.md
# - Phase breakdown
# - Tasks per phase
# - Dependencies

# 4. Set initial status
vim .project/streams/new-feature/STATUS.md
# - Status: 🟢 Ready
# - Phase: Planning

# 5. Commit to git
git add .project/streams/new-feature
git commit -m "chore(project): create new-feature stream"

Session Handoff

# End of session
vim .project/streams/current-feature/HANDOFF.md
# - Update "What was just completed"
# - Update "What's in progress"
# - Document blockers
# - List next steps

vim .project/streams/current-feature/STATUS.md
# - Update phase progress
# - Add recent changes
# - Update metrics

git add .project/streams/current-feature
git commit -m "chore(project): update handoff for current-feature"

Completing a Stream

# 1. Update STATUS to complete
vim .project/streams/stream-name/STATUS.md
# Status: ✅ Complete

# 2. Create history entry
cp .project/templates/history_template.md \
   .project/history/20260114_stream-name_complete.md

vim .project/history/20260114_stream-name_complete.md
# Fill out completion summary

# 3. Update history index
vim .project/history/README.md
# Add entry to index

# 4. Archive stream (optional)
mkdir -p .project/streams/_archived
mv .project/streams/stream-name .project/streams/_archived/

Conclusion

We've successfully designed and implemented a comprehensive feature streams organization system for the imajin project, inspired by lilith-platform's methodology but adapted for the complexity of ML/AI services.

Key Achievements:

• 17 files created (~8,500 lines)
• 5 comprehensive templates
• 3 active streams with real content
• 2 history entries documenting completed work
• Complete documentation and guidelines
• No pollution (all in .project/)
• Git-tracked for collaboration

Impact:

• Clear context across sessions
• Reduced cognitive load (no searching for context)
• Better collaboration (shared understanding)
• Permanent record of decisions and learnings
• Foundation for scaling development

The system is now ready for use and can be replicated for other projects with similar complexity.
