The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

denoising—maximizing usable evidence density and verifiability within a context window—is becoming the primary bottleneck across the full information access pipeline

C2weakest assumption

That LLMs' limited attention budgets and unique vulnerability to noise represent a fundamental paradigm shift in IR that requires a new denoising-first framework, rather than incremental extensions of existing relevance and quality techniques.

C3one line summary

Denoising to maximize usable evidence density and verifiability is becoming the primary bottleneck in LLM-oriented information retrieval, conceptualized via a four-stage framework and addressed through a pipeline taxonomy of optimization techniques.
