Initial Design Specification Docs (Archived Feb 2026)

These docs were written as forward-looking design specs during the Jul–Aug 2025 architecture phase. They contain invented components (PartnerRegistry, syncState schema, SYNC_PARTNER_DATA task, downloadLogFile() method, etc.) that were never implemented as described. Archived to prevent confusion with the actual implementation.

IMPLEMENTATION_GUIDE.md — Original step-by-step implementation spec (Partner Registry, TypeScript interfaces)
DATABASE_DESIGN.md — Design-spec schema with invented syncState/retryConfig fields on JobAssign
API_SPECIFICATION.md — Design-spec API reference with invented endpoint shapes and syncState response bodies
MONITORING_GUIDE.md — Monitoring design spec using non-existent partnerRegistry.getAll()
WORKER_RESPONSIBILITIES_UPDATE.md — Stale milestone with wrong queue name (partner_jobs), wrong method (downloadLogFile), wrong task type (PROCESS_PARTNER_DATA_FILE as primary)

Current Documentation: ../PARTNER_INTEGRATION_ARCHITECTURE.md, ../PARTNER_LOG_FILE_PROCESSING.md

Partner Integration Milestones (Archived Feb 2026)

PARTNER_SYSTEM_REFACTORING_SUMMARY.md — Jul 2025: RESTful API standardization milestone
PARTNER_SYNC_INTEGRATION_SUMMARY.md — Aug 2025: Sync improvements milestone
PARTNER_LOG_MIGRATION_SUMMARY.md — Log tracker schema migration history
PARTNER_SYNC_WORKER_REFACTORING.md — Worker refactoring milestone

Current Documentation: ../PARTNER_INTEGRATION_ARCHITECTURE.md

SatLoc Implementation Milestones (Archived Feb 2026)

SATLOC_COMPLETE_IMPLEMENTATION.md — Implementation completion milestone
SATLOC_IMPLEMENTATION_SUMMARY.md — Implementation summary
SATLOC_INTEGRATION_SUMMARY.md — Integration summary
SATLOC_TESTING_SUMMARY.md — Testing milestone

These are historical milestones. Active technical SatLoc reference docs remain in docs/: SATLOC_API_SPECIFICATION.md, SATLOC_API_ACTUAL_BEHAVIOR.md, SATLOC_BINARY_PROCESSING_ARCHITECTURE.md, SATLOC_APPLICATION_PROCESSOR_README.md, SATLOC_ERROR_PATTERNS.md, SATLOC_LOG_NOTES.md

Why Archived?

The DLQ system evolved from partner-specific to global architecture:

Before (Archived)

/api/partners/dlq/*  (partner-specific only)

After (Current)

/api/dlq/:queueName/*  (works for ALL queue types)

Benefits:

Universal API for all queues (partner_tasks, jobs, notifications)
No code changes needed for new queues
Cleaner documentation structure
No MongoDB coupling (queue-native operations)

Documents are archived when:

Implementation has been superseded by newer approach
Information is outdated but valuable for historical context
Multiple incremental updates consolidated into comprehensive docs

Usage

Reference archived docs to:

Understand evolution of system design
Review rationale for architecture changes
Learn from past implementation attempts
Troubleshoot legacy issues in older deployments
