Open Brain Session 9 retro: Massive build session. Went from 4 MCP tools to 16 in one session. Built all three extensions (Client Context, Content Pipeline, Business Operations) plus cross-extension intelligence (full_context tool + digest v2). Built and deployed Next.js dashboard to Railway (6 pages, dark theme, password auth). Key learnings: (1) Next.js Supabase client must use lazy init, not module-scope, or Railway builds fail without env vars. (2) Railway CLI is more reliable than Railway MCP for project creation. (3) sed find-replace misses multiline method chains, always check end-of-line patterns separately. (4) Supabase free tier Realtime quota spike was from Dashboard Table Editor tabs, not application code. (5) brain-digest extension context is wrapped in try/catch so empty extension tables never block delivery. Session touched 4 migrations, 12 new tools, 1 full web app, 1 digest upgrade.
