+# PARKED 2026-09-04: with the MXFP8→bf16 dequantized lab drafter the target
+# loads clean and the drafter loads (no missing params), but the FIRST draft
+# pass at warmup dies in _project_context_kv: "mat1 and mat2 same dtype —
+# BFloat16 vs Float8_e4m3fn" (the fused KV-proj weight ends up fp8 at
+# runtime — the NVFP4 target's quant config bleeds into the draft's linears,
+# and the lab drafter's layout doesn't survive that path; incoai's does).
+# The lab drafter belongs to the lab's own vllm fork (newer dflash + aux-
+# capture). Revisit with a lab-fork image build.
