  "title": "Non-Commutative State Tracking with Input-Dependent Low-Rank Updates in Mamba-3",
  "summary": "The method replaces Mamba-3's purely diagonal state transition with a diagonal-plus-rank-one, input-dependent reflection term, coupled with a modified chunkwise parallel training algorithm. The cost is a custom nonstandard kernel and training path that existing Mamba implementations and optimized inference stacks do not support, plus added implementation complexity, with no reported latency or memory figures. It can fail because benefits are demonstrated only on synthetic noncommutative tracking tasks (group word problems, shell game), so gains on conventional language or vision workloads are unestablished and ecosystem support is absent.",
  "rationale": "The technique addresses a niche state-tracking limitation with an unproven custom architecture and no reported efficiency numbers, so it is worth monitoring but not yet adoptable under constrained infrastructure.",
