# Project Plans Directory

This directory contains comprehensive planning documentation for the Advanced Second Brain PKM System, organized to support effective project execution and stakeholder communication.

## Directory Structure

### `project-phases/`
Detailed breakdowns of each development phase with specific deliverables, timelines, and dependencies.

- `phase-1-foundation.md`: Backend infrastructure and core services
- `phase-2-core-ui.md`: UI development and knowledge browser
- `phase-3-advanced-features.md`: AI agents and intelligent features
- `phase-4-integration-optimization.md`: Performance optimization and integrations
- `phase-5-production-launch.md`: Production deployment and scaling

### `technical-implementation/`
Deep-dive technical specifications, architecture decisions, and implementation strategies.

### `user-journeys/`
End-to-end workflow documentation covering key user interactions and system behaviors.

### `risk-mitigation/`
Contingency planning, risk assessment, and mitigation strategies for potential blockers.

### `milestones/`
Success criteria, validation approaches, and measurable outcomes for each project milestone.

### `checklists/`
Practical checklists for development setup, testing, and deployment readiness.

### Additional Planning Documents
- `directory-structure-templates.md`: Standard directory structures for knowledge domains
- `default-config-structure.md`: Configuration directory layout and default settings

## Relationship to Other Documentation

This plans directory contains **actionable implementation plans** that build upon the foundational documents in the parent `docs/` directory:

- **`docs/personal-notes/ImportantToMe.md`**: Core principles and requirements that drive all planning
- **`docs/grok-chat/Functional Specification*.md`**: High-level functional requirements
- **`docs/grok-chat/Technical Requirements*.md`**: Technical requirements and constraints
- **`docs/grok-chat/User Story*.md`**: Narrative user journeys and scenarios
- **`docs/UI/UX Design Document*.md`**: UI/UX specifications and design principles

The plans here translate these requirements into **concrete, executable steps** with timelines, dependencies, and success criteria.

## Planning Philosophy

### Dual Manifold Cognitive Architecture
Our system implements a revolutionary **dual manifold cognitive architecture** that models intelligence as the geometric intersection of individual and collective knowledge spaces:

- **Individual Manifold**: Personal cognitive trajectory with temporal evolution
- **Collective Manifold**: Domain expertise with social validation
- **Braiding Process**: Mathematical fusion of personal resonance (α) and collective feasibility (β)

### Subagent-Driven Development
Following the established pattern of using specialized subagents for complex tasks:
- **explore**: For codebase analysis and pattern discovery
- **code-task-executor**: For isolated coding tasks
- **project-completeness-auditor**: For validation and gap analysis
- **testing-agent**: For automated testing workflows
- **documentation-updater**: For maintaining documentation consistency

### Decision Framework
- **PRODUCTION BLOCKER** → Immediate priority (system crashes, data loss)
- **CORE FUNCTIONALITY** → High priority (primary user workflows)
- **INFRASTRUCTURE OPTIMIZATION** → Lowest priority (performance, scalability)

### Domain-Critical Validation
Always prioritize validating what we're building works over how efficiently we deliver it.

### Three-Layer Memory Architecture
- **Episodic Layer**: Raw content with hybrid indexing (dense + sparse)
- **Semantic Layer**: Temporal concept evolution and cognitive trajectories
- **Persona Layer**: Knowledge graphs with centrality measures and gravity wells

## Key Planning Principles

1. **Incremental Value Delivery**: Each phase delivers tangible user value
2. **Parallel Development**: Maximize concurrent workstreams where dependencies allow
3. **Early Validation**: Test critical assumptions (Dana runtime, file monitoring) early
4. **Flexible Scope**: Plan for MVP delivery after Phase 2 if needed
5. **Risk-First Approach**: Address technical risks before investing heavily in UI

## Critical Dependencies

- **Phase 1 → Phase 2**: Backend foundation required for functional UI
- **Dana Runtime**: Must be functional before agent development can begin
- **File System Integration**: Prerequisite for all user-facing features
- **API Contracts**: Clear interfaces between frontend/backend teams

## Success Metrics

- **Functional Completeness**: All core features implemented and tested
- **User Experience**: Intuitive workflows with acceptable performance
- **Technical Quality**: High test coverage, clean architecture
- **Documentation**: Comprehensive technical and user documentation

## Quick Start

1. Review `project-phases/phase-1-foundation.md` for infrastructure setup
2. Check `checklists/development-setup.md` for environment preparation
3. Use `milestones/mvp-definitions.md` to understand success criteria
4. Refer to `risk-mitigation/` for contingency planning

## Update Process

- Update plans after each completed milestone
- Review and adjust based on actual development velocity
- Document lessons learned and adjust future planning assumptions</content>
