Runtime Snapshots
Runtime Snapshots is the public technical series behind E2LLM and SiFR. It documents the practical problem: LLMs need reliable browser-state context before they can reason well about web UIs. This page indexes the series — it does not duplicate every article.
Runtime Snapshots #16 — The Three Architectures of Browser Agents
Start here. Positions structured runtime perception against vision-based agents and accessibility/tree abstractions.

SiFR foundation. Introduces the proposed structured representation for runtime browser snapshots.

Pipeline use. Why saved structured snapshots become workflow artifacts.

Broader direction. Future-direction content — not the headline; the structured-perception category comes first.
