Fashionpedia Neckline Attribute Reliability v1.0.0 Local Evidence

Scope

This release contains the hash-verified local evidence bundle for the Fashionpedia neckline-attribute verification study.

The confirmed comparison is a matched frozen SigLIP2 control versus an audited vision-attention LoRA adaptation on a fixed official Fashionpedia validation subset.

Confirmed result

• Official validation: 654 eligible instances across 644 images
• Source train/development to validation image overlap: 0
• Matched frozen control Macro-F1: 0.5798
• Vision-attention LoRA Macro-F1: 0.6681
• Absolute Macro-F1 improvement: +0.0883, or +8.83 percentage points

Claim boundary

This is a category-scoped seven-class neckline-attribute verification study. It is not a full Fashionpedia benchmark, consumer-to-shop retrieval benchmark, or production catalog system.

Verification

The ZIP SHA-256 sidecar and release evidence manifest are included with the asset bundle. Full checkpoint-presence and release-file hash contracts are validated through the separate local evidence gate.
