The 70% Wall
The failure point at which vibe-coded prototypes stall: a working UI is produced, but the last 30% of the application — business logic, data integrations, scalable architecture, authenticated flows, edge cases — requires architectural decisions that weren't made upfront. Getting past the wall typically requires rebuilding from scratch with proper requirements. A widely-reported pattern in the prompt-to-prototype category; the root cause is sequencing (code before requirements) rather than tool capability.

Tamper-proof logAn activity record that can't be quietly altered after the fact.Tech Stack CreepThe overload of apps and tools added to a business that creates complexity and confusion.Technical debtThe future cost of shortcuts taken in code today.TEE (Trusted Execution Environment)A hardware-secured environment that keeps data sovereign while running models at the edge.The 80–90% Wall (Vibe Coding)The point in a vibe coding session where forward progress stalls on a specific unresolvable blocker. The UI is working, the demo looks good, but one thing — a database query, an integration, a specific feature — won't respond to any prompt variation. You've tried ChatGPT, Perplexity, YouTube tutorials, re-prompting 47 different ways. Energy leaves. Project dies. The diagnostic: if you've tried the same thing three or four different ways and you're still stuck, you've hit the wall and need a real human with domain-specific tool knowledge.The Buzzing Phone LoopA product design principle for non-desk workers: route every meaningful product event — new lead, new review, new booking — to a phone push notification rather than an email dashboard. For contractors who never check email and may not own a laptop, the phone buzz is the product's entire UX. It creates daily engagement and tangible perceived value from a tool the user might otherwise forget is running in the background.The End of Enterprise UIThe thesis that enterprise business application interfaces — forms, dashboards, approval workflows, multi-step navigation designed for human clicks — will be progressively replaced by database-plus-chat architectures. The interface becomes voice, text, or messaging; users describe what they need and the system retrieves, processes, and presents. Ran's timeline: 2–3 years for most business process applications. Leisure UI (browsing, shopping, social) survives because humans want the experience. Business process UI winds down because the cognitive overhead of navigating it is work AI handles better.The Last Mile (App Building)The final 10–20% of app completeness that current AI tools cannot reliably cross alone: custom integrations with third-party services, edge-case business logic requiring judgment, and complex UI/UX flows that don't follow standard patterns. The last mile is why production-quality AI builders offer human assistance plans: AI generates a structurally sound, largely functional app; humans close the gap between 'mostly works' and 'production-ready.' Analogous to self-driving cars' difficulty with edge cases — the 80% is solved, the 20% requires the hardest work.
