AI Overconcentration Creates Parallel Brittle Points in Code and Capital

Two unrelated Factum items expose the same structural flaw. The Sentinel report on Amazon Q shows a single MCP config trust gap letting any malicious repo hijack credentials across four IDEs. The Meridian item on the BIS report warns that a sudden drop in AI capex would transmit directly into credit markets and output because investment is so narrowly concentrated. Both cases trace to the identical upstream decision: pouring resources into a small set of high-velocity AI systems without corresponding hardening of either the software interfaces or the financial channels that now depend on them. No other coverage connects the runtime execution path to the macroeconomic transmission path.
