+# Southborough death cards — structured extraction
+
+Handwritten **death-record index cards** from the Southborough (MA) Town Clerk collection
+([`biglam/index-cards-southborough-vital-records`](https://huggingface.co/datasets/biglam/index-cards-southborough-vital-records)),
+prepared for schema-conditioned extraction. Each card records a death: `name`, `date_of_death`,
+`place_of_death`, `place_of_burial`, `sex`, `condition`, `cause_of_death`, `age`, `occupation`,
+`birthplace` (+ volume/page).
+
+| config | cards | labels |
+|---|---|---|
+| `gold` | 12 | **hand-reviewed** ground truth (eval) — AI-drafted, human-reviewed, uncertain readings flagged |
+| `silver` | 127 | **machine-generated** labels (Qwen3-VL-8B from the image) — SFT data, *not* hand-verified |
+| `pool` | 160 | **unlabelled** image pool — re-label with your own model/schema |
+
+Training (`silver`) and evaluation (`gold`) data for the [index-card-extractor-4b](#) research model;
+`pool` is the unlabelled source for `silver`. ⚠️ `silver` labels carry model noise on free-text fields.
