✓ Portable graph bundle live · download bundle · merged state

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

RILKE scales effectively to large-scale benchmarks, demonstrating high edit success and strong paraphrase generalization while preserving general utility with modest memory overhead.

C2weakest assumption

The assumption that two key properties of the representation space enable fine-grained control over complex unstructured knowledge without cross-edit interference or loss of general utility when base weights remain frozen.

C3one line summary

RILKE learns low-dimensional, paraphrase-robust modules in LLM representation space that enable interference-free lifelong knowledge edits while preserving base model utility.
