Writability and the Pathway: A Controlled Study of Knowledge Injection into Addressed Memory

Addressed conditional memory provides a local surface for post-hoc knowledge injection, but a successful write need not transfer to a new question or preserve untargeted behavior.

Key points

  • This study combines a controlled GPT-2 comparison with production-memory experiments on Qwen3.8-Flash-Next-FP8 and DeepSeek-V4.1-Flash.
  • Anchoring lowers measured drift; lexical hits do not establish entity-specific retrieval.
  • Six DeepSeek zero-order cases yield one new target-token promotion and one regression.
  • These results support bounded writing feasibility and separate trained expression, question-form behavior, and preservation; first-token rankings do not establish complete-answer success or universal conditions for writable memory.
