+# CHANGELOG — Super Search for Business
+
+---
+
+## 2026-07-25 — Project Inception
+
+**Decision:** Build a commercial competitive intelligence SaaS product on top of existing Super Search v2 and OSINT infrastructure.
+
+**Deliverables created:**
+- Product specification (`docs/super-search-business-spec.md`)
+- Architecture diagram (`docs/super-search-business-architecture.html`)
+- Project README with deployment, recovery, and URL planning
+
+**Key architectural decision:** The product is an 80/20 build — 80% already exists (Super Search v2, OSINT enrichment, 7 search providers with fallback chains, MCP protocol) and 20% needs building (multi-tenant REST API, React portal, Stripe billing, PostgreSQL schema).
+
+**Naming candidates evaluated (30+ domains checked):**
+- IntelSight (intelsight.io — available)
+- ScopeIntel (scopeintel.io — available)
+- BrandSleuth (brandsleuth.io — available)
+- RivalEye (rivaleye.io — available)
+- BizScope (bizscope.io — available)
+
+**Structural decision:** Product should have its own brand and domain, listed as an IT Pro Partner product (same model as VoIPSimplicity). Footer: "A product of IT Pro Partner."
+
+**Pricing model:** Three tiers — Starter ($199/mo), Pro ($499/mo), Enterprise ($1,499+/mo). 93-95% gross margins.
+
+**Open decisions:**
+- Final product name
+- Hosting target (app1 shared vs. dedicated VPS)
+- Data retention policy
+- Rate limit definition for Starter tier
