Tier C — Historical. This document is a point-in-time snapshot preserved for reference. For current architecture, see CANONICAL_PLATFORM_ARCHITECTURE.md.

Locked Backend Consolidation — Ready to Go Live

Status: ✅ COMPLETE + LOCKED
Date: June 27, 2026
Architecture: 15-Layer Platform (All layers implemented)
Gateway Contract: Frozen (30 endpoints)
Deployment: Production-ready

WHAT WAS CONSOLIDATED

Yesterday's Session

  • Recovery Vision (Human-centric product)
  • Platform Activation Framework (8 frozen contracts)
  • Core Engine (Event ingestion + AI routing)
  • L1 Chat Shell (First-class chat interface)

Today's Session

  • integratewise-ai-workspace features (all runners, agents, workflows)
  • integratewise-live repo features (chat, recovery vision, projections)
  • Complete architecture diagram (15 layers, final platform)
  • Backend locking strategy (Gateway as single contract)

Result

One unified, locked, production-ready backend that powers all frontends.
