From Silicon to Pixels: Why No AI Agent Can Ship a Production Browser — A 35-Million-Line Engineering Autopsy

A distinguished-architect's silicon-to-pixel dissection of why production browsers remain categorically beyond AI agent capabilities. Spanning GPU command buffer validation, TDR fault recovery, seccomp-BPF syscall confinement, the Unicode bidirectional algorithm, OpenType GPOS shaping tables, QUIC transport internals, WebAssembly sandboxing, accessibility tree construction, image decoder attack surfaces, and the formal verification boundaries that separate plausible code generation from provably correct systems software. Grounded in peer-reviewed research, hardware specifications, W3C/WHATWG conformance data, and two decades of shipping systems that survive adversarial production.

When Your LLM Trips the MMU: Page Faults, TLB Shootdowns, and the Hidden Virtual-Memory Tax of AI Inference

A distinguished-architect deep dive into GPU virtual memory internals, MMU fault pipelines, TLB shootdown mechanics, page-table walks, Unified Memory/HMM coherence, ATS, and why page migration turns your p99 into a hardware problem nobody on the team budgeted for.
