CPP Tender Audit Tool

Investigate 16.5M Indian government tender and award records — who won the contract, for how much, and whether the bidding was competitive.

The shell (filter bar + card skeletons) renders within ~2s of a cold load. DuckDB-WASM and the initial R2 partition download warm up in the background with a visible progress bar, while the build-time data-loader JSON populates the default All India views instantly — before the WASM engine is ready. Applying a state / year / sector filter triggers a live DuckDB-WASM query against R2 Parquet using the dedup-JOIN pattern (D004/M009).
