AeroPulse

Live OpenSky ingestion into a bronze, silver, and gold medallion lakehouse on dbt and DuckDB with schema tests at every hop, an Isolation Forest ranking anomalous flights, and a Streamlit dashboard on the gold marts. Rebuilds offline from a deterministic seed.

DriftGuard

PSI, KS, and Jensen-Shannon on every feature. Retrains only on real performance loss, judges the challenger on recent rather than reference data, promotes on a margin, and recovered AUROC 0.72 to 0.88 with no human intervention. The drift detector itself is graded against labelled scenarios. 24 tests.

Sahayak

Planner, executor, and verifier over function calling. SQL forced read-only and row-capped, Python sandboxed with no imports or network, and an eval harness that compares against independent reference queries the agents never see. 27 tests.

ClinicalPulse RAG

Answers only from retrieved passages with a source and page citation per claim, refuses out-of-scope and patient-specific requests, and shows retrieval diagnostics.
