Capstone A: Campaign Classifier

# Capstone A: Campaign Classifier ## Brief Ship the full campaign classifier: time-split validation, calibrated model, cost-matrix threshold, decision memo. Deterministic checks then LLM review. ## Dataset Full campaign data + hidden holdout window. ## Starter guardrails (88) - Full pipeline from the m2-l8 skeleton; threshold frozen pre-holdout. - Memo template: decision, metric table, calibration evidence, risks. ## Deterministic checks Holdout PR-AUC >= 0.70; Brier <= 0.16; temporal split intact; memo complete. ## 100-pt rubric - Validation discipline: 20 - Model + calibration quality: 25 - Threshold economics: 20 - Holdout metric bar: 15 - Decision memo: 15 - Reproducibility: 5
