| # 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)` | |
| ## Counts | |
| - Sample patents fetched: 50 | |
| - Retrieval status: ok | |
| - Patents with numeric keyword spans: 36 | |
| - Numeric keyword spans: 191 | |
| - High-attention manual-review spans: 35 | |
| - Raw numeric span yield per 100 patents: 382.0 | |
| - High-attention review span yield per 100 patents: 70.0 | |

| ## 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 | |
