# Patent substantivity Phase 0 probe

This is a retrieval/span feasibility artifact only. It does not merge into Poucher, train a model, push to Hugging Face, or bump a version.

## Query Gate

- `("substantivity" OR "tenacity" OR "longevity") fragrance (C11B9 OR A61Q13) (hours OR score OR panel)`
- `("fragrance intensity" OR "odor intensity") (skin OR fabric OR hair) (hours OR "after application") (C11B9 OR A61Q13)`
- `("retention" OR "persistence") perfume compound (hours OR table) (C11B9 OR C11D)`

- Spans with a printed compound reference or CAS: 35/191

## Poucher Alignability

Not established by this automated span probe. The constructs found here are method-specific patent constructs; merge eligibility still requires resolved overlapping molecules and an empirical correlation against `data/poucher_substantivity.jsonl`.

## GO/NO-GO

NO-GO for full build until manual/LLM review converts spans into true single-molecule measured tuples and confirms construct overlap; this probe validates query retrieval and estimates raw span yield only
