Spin guard: derivative-work rule (AGENTS.md) + rationale (ai.md) — proactive external scan cites in commit msg; 2nd failed fix = STOP and research externally, never a 3rd guess

Project lesson cited (the 2026-08 web-box saga, 9 commits): browser sources are fixed canvases per OBS convention — the 'gap' was a widget CSS glow, not a bug.

 ## Key facts / landmines

+- **Why the web-box saga spun (2026-08):** nine commits of in-head theorizing for a problem
+  OBS already solved (browser source = fixed canvas, box = user-sized, content clips at the
+  edge). The apparent gap was the widget's CSS glow, not a bug. → AGENTS.md now mandates
+  external research on the second failed fix and proactive scans for new features.

 - **App running locks `ytLive.exe`** → build fails MSB3027 until creator exits the app.
 - **Startup diagnostics:** unhandled exceptions + checkpoints go to `%APPDATA%\ytLlive\startup.log`
  (`Helpers/AppLog.cs`). On a silent startup crash, read that.
