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)

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
