+## Loaded-Comfy Projection Module Probe
+
+The source audit was followed by a direct replay against tensors consumed and
+produced by the actual loaded Comfy layer-0 modules. This proves the remaining
+difference is present **before attention** and is not inferred from source.
+
+| Item | Evidence |
+| --- | --- |
+| Capture location | `/tmp/fl2va-qwen0-loaded-modules` on Spark |
+| QKV capture SHA-256 | `8998722e73ba24c40c09a86133ccdb22b708998a3e8b8fb4c4293227345f19db` |
+| MLP capture SHA-256 | `e52ed70f4aa76f1ba26302b9955631d8f490fb6dc269d96a0ce3e1ea981e7ac2` |
+| Loaded Comfy class | `comfy.ops.mixed_precision_ops.<locals>.MixedPrecisionOps.Linear` |
+| Loaded Comfy weight | `comfy_kitchen.tensor.base.QuantizedTensor`, logical dtype BF16, `TensorCoreNVFP4Layout`, full precision enabled |
+| Q/K/V dimensions | `(8192,5120)`, `(1024,5120)`, `(1024,5120)`; no pre-scale |
+| Gate/up/down dimensions | `(25600,5120)`, `(25600,5120)`, `(5120,25600)`; only down has pre-scale |
+
+Direct replay on the **identical loaded-Comfy module inputs**:
+
+| Projection | Mean absolute error | Maximum absolute error |
+| --- | ---: | ---: |
+| Q | `6.11124e-05` | `0.0019514` |
+| K | `8.47002e-05` | `0.00167805` |
+| V | `5.4459e-05` | `0.00098893` |
+| Gate | `0.000308973` | `0.0082469` |
+| Up | `0.00028138` | `0.00792789` |
+| Down, using Comfy's captured activated input | `0.000424157` | `0.0500984` |
+
+**Conclusion:** same checkpoint tensors, same BF16 inputs, and the same named
+Kitchen layout do not currently produce identical projection outputs through
+direct `Nvfp4Linear` and Comfy's loaded `MixedPrecisionOps.Linear`. The next
+investigation must capture/compare the effective `QuantizedTensor` parameters
+and direct packed-weight wrapper at dispatch time. Do not revisit attention,
+sampler, or MLP ordering until that exact module-dispatch difference is found.
