What UBER taught the scorers
A single-ticker spot-check on UBER scored 38 and 35 across Trading and Investing modes. Three days later it scored 67.5 and 68.9. The fix needed a written investing rubric, three converging scorer bugs, and one structural one.

Insider chips, and the no-data drag
Phase 4 of a smart-money pivot shipped: insider activity is now a confluence layer and insider trades render as chart overlays. Then the top-picks sort started favoring the symbols with the least data. Four bugs deep, one structural lesson.

Three audits, three layers
Four more phases of Smart Money shipped this week. Each one moved on the back of an audit — surfaces, seed data, then composite-score correctness. Each audit caught one class of mistake and missed the others.

What ten years of bars said about Nova Score
Phase 7 closed the credibility loop on Nova Score by measuring how each zone has actually performed at +5d/+10d/+20d/+30d/+50d across the universe. The answer was uncomfortable.

Lookup, Cmd+K, and the skill-bus pattern
A TradingView-style symbol panel, a global Cmd+K palette, and a small architectural pattern that lets skills broadcast renderer events without becoming Electron-aware.

Production polish: custom icons, orphan processes, and the Windows tree-kill problem
Three production-build war stories from a single week — afterPack rcedit, an EADDRINUSE loop on port 3000, and the cmd→npx→node grandchild that survived every kill signal until taskkill /T fixed it.

The case of the hallucinated earnings date
A thesis card claimed an earnings date in April 2024 while it was May 2026. Here is the full root cause, the three-layer fix, and the reusable date-grounding helper that is now standard issue for every Nova LLM call.

Building a stock screener inside Nova
Multi-confluence ranked ideas, free-data-first, hybrid AI/template thesis, ATR-based levels, and a backtest engine that turns a chat tool into something I'd actually trade off of.

Skills as plugins: a tool-use plugin system that scales past 20 tools
Why every Nova capability — calendar, CRM, vault, screener, portfolio — is a plugin package, what the contract looks like, and how a chat-time skills picker keeps tool sprawl from drowning the model.

Voice as a primary interface: Whisper, Silero, Cartesia, and an orb
Push-to-talk on Ctrl+Space, hands-free with VAD, local STT, streaming TTS, barge-in. The latency budget that makes Nova feel alive instead of like a chat window with a microphone glued on.

The brain swap: pluggable AI providers in one chat loop
How Nova flips between Claude, Gemini, Ollama, OpenRouter, and an unofficial Claude Max proxy mid-conversation — and the five gotchas that made the Max provider painful.

Picking the stack: Electron, Next.js, and the Vercel AI SDK
Why a Jarvis clone in 2026 ends up as a pnpm monorepo with an Electron main process, a Next.js renderer, and a swappable provider layer.

Why I'm building Nova
An origin story for a Jarvis-inspired desktop AI assistant — built for me, by me, on top of the model APIs I already pay for.
