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 docs/plans/README.md
