E-001: Platform Foundation

Status: Done Owner: @bilal @deen

What Was Done

• Supabase-first local development stack (Docker, migrations, seed auth)
• Stub LLM + embeddings + notification providers for offline development
• Vitest test framework (42 tests) + webhook fixtures
• GitHub Actions CI (lint + test on PR)
• Anthropic + OpenAI integration for tenant engine E2E
• Twilio/SendGrid package setup + public routes + dev guard

Key Decisions

• Supabase local replaces bare Docker PostgreSQL
• Stub providers enable fully offline development
• LLM_PROVIDER=stub returns deterministic responses for testing
