Every word, every session.

pgvector over Pinecone — cost matters more than managed infrastructure at this stage. HNSW with cosine ops, threshold 0.78 for cluster assignment.

Hybrid recall pipeline: pgvector cosine top 30 + BM25 tsvector union → Haiku 4.5 reranker on Pro tier. Free tier returns pure cosine top 5 with no rerank.

Next.js 15 App Router, TypeScript strict mode, Tailwind 3.4. No Shadcn, no Radix — custom components only. Inline JSX styles in generated fragments.

Supabase on ap-southeast-2 (Sydney). Same region as Vultr VPS matters for latency. Coolify handles auto-deploy on git push to main. Never `npx vercel --prod`.

Deploy = git push origin main → Coolify Dockerfile build → auto-deploys to VPS. Vercel is backup only. The Coolify webhook fires on every push to main.

Prefer Claude Code over Cursor. Claude Sonnet 4.6 for most tasks, Groq llama-3.3-70b free tier for LLM calls in the synthesis engine. Anthropic API is last resort.

Tailwind over CSS modules for all client sites. Mobile-first always — test at 375px as the floor. Inline styles in JSX fragments only (no class leakage between generated pages).

Resend for transactional email, Stripe for payments. Never SendGrid — reliability issues Q3 2025. Stripe webhook secret goes in Coolify as STRIPE_WEBHOOK_SECRET.

Client: Aerna (sustainable fashion brand). Contact: Sarah Chen, founder. Budget $5K AUD fixed. Shopify integration read-only — pull product and order data only.

Testing stack: Playwright for e2e, Vitest for unit. Playwright specs gate on SPINE_EXT_HARNESS=1 so CI never accidentally triggers live browser sessions.

Building automated income. First SaaS MRR before June 2026. Revenue target $1M in 2026. Agency = cash flow, SaaS = wealth. Never confuse the two.

Content Autopilot is the $1 MRR wedge. Spine is the long play — developer wedge via MCP, then normie market via Chrome extension for ChatGPT and Gemini.

Three-tier offer: Premium ($5K+ custom builds), Intermediate ($1-2K sites), Basic (template + setup). Premium pays for SaaS runway. Never sell Basic at a loss.

ABN: 46 248 687 420. Sole trader. No employee costs, no payroll. Keep legal surface minimal until $100K ARR. Stripe needs age 18 — bank transfer primary until then.

Design floor: Awwwards SOTD. Every site must feel hand-crafted. No symmetrical 50/50 layouts. Fibonacci spans: 13fr/8fr/5fr. Never ease-in or ease-out — spring physics only.

MCP is the Anthropic-blessed protocol for AI tool extensions. The wedge: `npx @spine/mcp init` registers Spine with Claude Code and Claude Desktop in 30 seconds.

Claude Code MCP config: .claude/mcp.json. Claude Desktop: ~/Library/Application Support/Claude/claude_desktop_config.json. Both accept the same mcpServers JSON schema.

Spine MCP tools: spine_remember(fact) stores any string, spine_recall(query) returns top-k relevant via vector search, spine_forget(id) soft-deletes. All user-scoped via RLS.

Embeddings: OpenAI text-embedding-3-small (1536-dim). Cost: $0.02/1M tokens. Zero-day retention on the Embeddings API — OpenAI does not store the content we send.

Proactive injection: before each session, pull top 5 relevant memories via cosine search and prepend as system context. Haiku 4.5 filters relevance cheaply before injection.

Spring physics only: stiffness + damping. Never ease-in, ease-out, or linear. Framer Motion for UI springs, GSAP for scroll-driven sequences. Always 400-600ms breath pace.

Fragment rule: minimum 400 lines per hero fragment, 7 visual depth layers each. The engine's power = stored code complexity, not prompt engineering. LLM job is selection only.

WebGL shaders require: simplex3D noise (not Perlin), domain warping (2+ FBM octaves), uTime animated + uMouse cursor reactive. Canvas compositing at 0.35-0.45 opacity always.

Self-healer validates generated code before mounting: AST tag balance check, 11 regex fixers, then LLM fallback if both fail. validateFragmentTags() is the entry point.

Genetic breeding: score output on 8 dimensions → store lessons → evolve winning patterns. Training loop runs daily at 3am UTC, 1 cycle max, $0.05 cap via Groq free tier.
