Two more findings from the hosted-TE GPU smokes:
- Module.dtype reports the first floating parameter, which after the
layerwise fp8 cast is the fp8 STORAGE dtype. Flux2 derives its prompt
embed and latent dtypes from encoder.dtype and feeds them to
randn_tensor, which has no fp8 kernel, so ANY flux.2 load with
text_encoder_quant=fp8 crashed at generation (pre-existing, runtime
cast included). The cast now swaps in a subclass whose dtype property
reports the compute dtype; forward behaviour is unchanged.
- The dense transformer_quant fast path assembles companions through
_assemble_pipe, which never received the pre-cast TE injection, so the
hosted encoder engaged on full-pipeline and GGUF builds but not on the
fast path. Threaded through like the other two branches.
Verified live on B200: qwen-image (full pipeline), flux.2-dev (GGUF picker
with int8 DiT prequant), ltx-2 (video backend) all engage the hosted TE,
render non-black, and report text_encoder_quant=fp8 truthfully.
