Thread Context — CreativeOS Architecture Triangulation

Where Things Stand

Architecture decisions are made and fully documented. The synthesis document and project README are the authoritative references. The next phase of CreativeOS work should build on these decisions — specifically Phase 1 (Foundation) from the roadmap: PostgreSQL + Supabase setup, Next.js scaffold, basic auth, and the creative project CRUD model.

Key File Locations

  • Architecture synthesis: rootphi-core/creativeos-architecture-synthesis_2026-03-27.md — the primary deliverable, contains all consensus scores, disagreements, unique insights, phased roadmap
  • Triangulation brief: rootphi-core/creativeos-triangulation-brief_2026-03-27.md — the 4 questions and context sent to providers
  • Project README: claude-context/projects/rootphi-core/README.md — condensed version of architecture decisions with build phases
  • Updated triangulator config: rootphi-core/skills-source/llm-triangulator/config/llm-triangulator-config.json — source-of-truth with gemini-2.5-pro

What a Future Session Needs to Know

  1. The architecture is decided — don't re-debate the stack. Reference the synthesis document for rationale.
  2. The n8n webhook workflow works for triangulation but requires Chrome JS (not Python) due to sandbox.
  3. The installed triangulator skill still has stale configs (Together AI key, Flash model). The skills-source copy is correct. Repackaging is pending.
  4. Google API is on paid plan now — Gemini 2.5 Pro works, no more free-tier quota errors.
  5. The "first tenant" productization model means: build everything for Brian's use case first, then extract the platform.

Phased Build Plan (from synthesis)

  • Phase 1 — Foundation (Weeks 1-4): Postgres + Supabase, Next.js scaffold, basic auth, creative project CRUD
  • Phase 2 — Intelligence (Weeks 5-8): LangGraph orchestration, pgvector embeddings, basic knowledge graph
  • Phase 3 — Canvas (Weeks 9-12): tldraw integration, custom shapes, real-time collaboration
  • Phase 4 — Automation (Weeks 13-16): n8n workflow templates, event system, external integrations
  • Phase 5 — Multi-tenancy (Weeks 17-20): Tenant isolation, onboarding, usage metering, "CreativeOS" branding
