What this means for you
How the finding was decided
The reported internal finding uses the fixed, thresholded decision rule recorded for mv-1.4; it is not a test for any non-zero floating-point value. This rule is not, by itself, a measured noise floor for this model.
Text output is evaluated separately under exact greedy token-sequence comparison. The outcome is on the fixed input set, not a population rate or a capability score.
Structural coverage: 24 contributing probes per evaluated position. This is neither the number of output continuations nor a count of independent tasks.
Observed responses through the model
No difference was observed at any evaluated position under this contract.
0 of 25 evaluated positions show a difference. This count describes the reach of the observed response, not its size or the number of changed weights.
| Recorded output | Observation |
|---|---|
| embedding output through decoder block 3 output | not evaluated |
| decoder block 4 output through decoder block 27 output | no difference observed |
| final normalized output | no difference observed |
Blocks are numbered from 1. Final is the output after the last normalization; the last block before normalization is not separately displayed. Not evaluated means no observation was made there; it is not a below-threshold result.
A difference can propagate from one output to later outputs. This view does not locate edited weights, identify a cause or show which capabilities changed. Controlled small-model findings are not a validation result for this model or execution environment.
What differs between A and B
| Artifact metadata | Recorded comparison |
|---|---|
| Model configuration semantics | matched |
| Tokenizer semantics | matched |
| Generation settings semantics | matched |
Recorded relation: combined artifact change. Do not attribute the finding to fine-tuning or weights alone.
Matched refers only to the recorded semantic summaries. It does not mean the complete artifacts are identical. Different configurations, tokenizers or generation settings can matter alongside weight changes.
Measured weight changes Same artifact pair and recorded response measurement
Overall relative weight change: 0.0%. Internal response: No difference observed. Text output: Unchanged on the evaluated inputs.
Coverage: 339 unique parameter tensors; 7615616512 values. All declared floating parameters were checked; 0 shared names were counted once. Buffers are outside this weight summary.
Numerical validity: all checked values are finite. Observed precision: bfloat16. Zero values: reference 17928, candidate 17928.

Relative change uses the reference norm; a zero reference has no relative percentage. Shared parameters belong to their first recorded group. The last block output is not separately measured; its row shows the final normalized output. Weight changes locate parameters to inspect, while response differences can propagate from earlier blocks. Neither identifies the cause of a task outcome.
Use the changed groups to choose targeted follow-up evaluations. No observed response difference does not establish equivalence, and a larger weight change is not a quality or severity score.
Recommended next checks Guidance, not a measurement
- Control the comparison contractReview the metadata differences above. Establish comparable tokenizer and generation settings before interpreting an output comparison; preserve each artifact revision.
- Run the relevant regression setCompare A and B on the tasks your users rely on, including output format and failure cases. Set acceptance criteria before inspecting the results.
- Keep an auditable decisionRetain this report with the task results and deployment revision. Separate the measured observation from your release decision.

No operational receipt is included in this copy. No signing or deletion claim is made.
Recorded context
Pin these fields when you diff this report against a future scan. Matching context is a prerequisite for interpretation, not proof of the cause of a difference. These recorded public identities help identify the input artifacts. This review copy is unsigned; no customer verification receipt is attached.

Reading this report alongside another scan
Check the artifact pair, revisions and measurement contract first. The categorical findings describe each recorded comparison; they do not rank different models. A different contract or execution environment needs its own comparability evidence. No numerical severity score is supplied.
Use as a checkpoint reference
For supported checkpoint comparisons, retain the starting revision, this measurement contract and the output settings with your training record. Compare the next checkpoint against that same reference, then retain its task results alongside the scan.
| For the next checkpoint | Record alongside this scan |
|---|---|
| Reference and candidate | Exact repository revisions |
| Comparable measurement | Same instrument, input contract and approved execution profile |
| Training change | Your fine-tune, merge or pruning record |
| Adoption decision | Your task acceptance results and deployment revision |
A reference record supports change tracking. It does not define an optimal model or a target score for training. Simulation results describe the simulated state; actual checkpoint changes require their own before/after comparison.
Your findings and the protected instrument
The observation, output-text status, artifact context and, where applicable, metadata comparison, plus provenance and categorical depth detail when included.
Raw profiles, per-item records, probe construction, thresholds, transformations and internal traces. The report contains no model weights, credentials or infrastructure identifiers.
This descriptive result does not identify cause, capability, quality, safety or deployment impact. It is not a task-quality measurement. Do not target a layer or make a shipping decision from this report alone. No calibrated risk or pass/fail grade is assigned. No cross-model ranking or cross-device bitwise-equality claim is made.
Historical results under superseded estimators do not validate this release. The categorical depth view, when included, describes recorded responses; it is not a diagnosis of edited weights.
