Summary

Establish a standardized documentation structure across all 7 ecosystem systems (common_system, thread_system, logger_system, container_system, monitoring_system, database_system, network_system) to improve consistency, reduce duplication, and enhance developer experience.

Background (Why)

• Documentation structures vary significantly across systems
• Multiple files exist at root level that should be in docs/ folder
• Duplicate documents exist (e.g., CHANGELOG.md at root and docs/)
• Similar documents (FEATURES vs CAPABILITIES_SUMMARY) cause confusion
• BASELINE.md location inconsistent (benchmarks/ vs docs/performance/)
• No standardized documentation template across systems

Current pain points:

• Developers must learn different documentation layouts for each system
• Duplicate content leads to outdated information
• Root-level documentation clutter affects repository readability
• Finding specific documentation requires searching multiple locations

Impact Analysis (Where)

Files to Relocate

Duplicate Documents to Consolidate

Implementation Plan (How)

Phase 1: thread_system Cleanup

• Move ARCHITECTURE_DIAGRAM.md to docs/
• Merge THREAD_SYSTEM_CAPABILITIES_SUMMARY.md into docs/FEATURES.md
• Delete EXPLORATION_SUMMARY.md
• Consolidate docs/advanced/01-ARCHITECTURE.md, 02-API_REFERENCE.md

Phase 2: network_system Cleanup

• Delete root CHANGELOG.md (keep docs/CHANGELOG.md)
• Move BASELINE.md to docs/performance/
• Move STRUCTURE.md to docs/ (merge with PROJECT_STRUCTURE)
• Move MIGRATION.md to docs/advanced/
• Move UDP_SUPPORT.md to docs/guides/

Phase 3: BASELINE.md Standardization (All Systems)

• Ensure all BASELINE.md files are in docs/performance/
• Update benchmarks/BASELINE.md to link to docs/performance/

Phase 4: Documentation Guidelines

• Create DOCUMENTATION_GUIDELINES.md template
• Apply consistent structure across all systems

Child Issues

• docs: Relocate root-level documentation files and consolidate duplicates thread_system#519 - thread_system: Relocate root-level documentation files
• docs: Consolidate duplicate documentation and relocate root-level files network_system#543 - network_system: Consolidate duplicate documentation files
• docs: Standardize BASELINE.md location across all ecosystem systems #304 - All systems: Standardize BASELINE.md location
• docs: Create documentation structure guidelines template for ecosystem #305 - Create documentation structure guidelines template

Acceptance Criteria

• No documentation files at root level (except README.md, README.kr.md)
• No duplicate documents across systems
• All systems follow standardized folder structure
• Documentation navigation (docs/README.md) exists in all systems
• BASELINE.md consistently in docs/performance/ across all systems
• All cross-references updated to reflect new locations
