2026-09-25: Pool-free allocation of a GLM-5.3 KDA layer’s per-sequence state.
The state is the SSM pool’s SsmLayerState, not a GLM type:
rollback_ssm_states_dispatch downcasts the state of every LinearAttention layer to that
type, and every KDA layer is LinearAttention.
Owner: model-arch (GLM-5.3). Invariants: none beyond the types.

(
h_is_f16: false), zeroed, with no checkpoints or intermediates. The model path uses pool slots instead (Glm5NextLayer::uses_ssm_pool).
