Collected with this tool against https://api.deepseek.com/v1, model id deepseek-flash (API name: DeepSeek-V4.1-Flash), standard preset (8 cells x 25 samples), protocol one-token/v1, reasoning disabled via the openai-effort adapter. 200/200 valid, 0 errors. Unlike the bundled Zenodo samples, this reference is protocol-matched to the package battery, so compare()/verify() against it is a direct comparison.
Reference fingerprints (trusted, collected with this tool)
These are first-party references — collected by llm-fingerprint-detector
itself against a provider you trust, using the package's own one-token/v1
battery. Unlike ../reference-fingerprints.sample.json (Zenodo paper data,
bruckner-zenodo-2026 protocol), these are protocol-matched, so a
compare() against them is a direct, non-indicative comparison.

Caveat: references drift as providers ship model updates. Re-collect if the
file is more than ~1–2 months old, or if a verification you trust starts
returning uncertain.
