Merge Report — LabOpen v1 merged FP8 weights

This document records how the merged full-weight checkpoint in this repository was produced from the LoRA adapter, and how it was verified. Internal filesystem paths are omitted; digests are reproduced verbatim from the training run.

Method

Per target module (LoRA r=4, alpha=4, scaling 1.0, 496 modules = 400 blockwise-FP8 + 96 BF16):

Dequantize base weight: W = codes * scale per 128x128 block (FP32)
Add LoRA delta: W_merged = W + (B @ A) * scaling
Re-quantize per 128x128 block: scale = amax(|block|)/448, codes clamped to +-448 (e4m3)

Non-target tensors are byte-copies of the base. Tensor layout, shard split and file format are identical to the base FP8 release.

Provenance

Trainable digest (checkpoint B): 96ef57e87e0d64de0340f9b917f4b9a7276356908bc6a5a7e59caa594bf68e03
FP8 modules merged: 400; BF16 modules merged: 96; override tensors written: 896 (400 weights + 400 scales + 96 weights)
Total checkpoint size: 30,866,663,264 bytes

Re-quantization error (vs exact FP32 merged weights)

Mean relative error: 0.330%
Max relative error: 1.00 (isolated near-zero elements; same order as the FP8 storage noise the base itself carries)

Output-equivalence probes (greedy, 3 prompts x 48 tokens)

A. In-memory merged model vs adapter (scales in FP32):

Prompt	Prefix-equal tokens	Token match
A 2 kg block slides down a frictionless ...	41/48	87.5%
def quicksort(arr):

if len(arr) <= 1... | 48/48 | 100.0% |

| Water flows at 3 m/s through a pipe of d... | 1/48 | 4.2% |

B. Saved-and-reloaded checkpoint (the published artifact, scales serialized BF16) vs adapter — release gate:

Prompt	Prefix-equal tokens	Token match
prompt 0	48/48	100.0%
prompt 1	48/48	100.0%
prompt 2	48/48	100.0%

Gate result: PASSED — 3/3 prompts, 144/144 tokens identical to the adapter trajectory.

Notes

The adapter (adapter/) remains the numerically exact training artifact; the merged checkpoint adds only the measured re-quantization error above.
Probes ran on the training stack runtime (identical kernels to the serving configuration used for evaluation).
