What problem does it solve? A fresh local development stack shows no activity on the Activity pages because ClickHouse contains no usage rows, making it impossible to verify Activity Explorer features like top-N charts, Other buckets, granularity rollups, and CSV exports. ## Core Features & Use Cases - Deterministic Seeding: Generates predictable usage data for a specific Clerk user and workspace with configurable date ranges, model counts, and empty days. - Scoped Re-runs: Clears only the selected user, workspace, and past date window before inserting, so re-seeding never duplicates rows or touches current-day data. - Verification Guidance: Documents ClickHouse query traps (DateTime offsets, 35-day TTL), server-side analytics caching, and UI verification steps for the Activity Explorer. - Use Case: After starting the local stack, seed 15 models across a date range with designated empty days, then confirm the chart's top-N and Other buckets, aggregate table statistics, and CSV export behave as expected. ## Quick Start Ask the assistant to seed deterministic Activity Explorer data for your Clerk user and workspace over a chosen date range, then verify the results at /activity/explore.
