+# Jobs job-category classifier (sklearn)
+
+      This repo holds the trained artifact used by the **jobs-ai-shared** package
+      (`jobs_ai_shared.library.categorize`) for the findjobs taxonomy.
+
+      - **Weights:** `category.pkl` — pickled scikit-learn `Pipeline` (`TfidfVectorizer` +
+        `LogisticRegression`), plus artifact keys `fields` and `input_joiner`.
+      - **Upstream:** Produced by ``scripts/train/train_category.py``.
+      - **HF repo:** `gateswang00/job_classifier`
