# Instructions
## Goal
Process end-of-day settlement for a gaming platform by:
1. **Generating a Daily Leaderboard:** Create a new table named `leaderboard_YYYYMMDD` containing the top 100 players ranked by their total daily score.
2. **Updating Historical Statistics:** Insert aggregated daily metrics for all players into the master `player_historical_stats` table.
## Prerequisites
- **Access:** Ensure the AI agent has the necessary permissions to run queries and create/update tables in the target Google BigQuery project and dataset.
- **Context:** The user request must specify the target date for processing (e.g., "today", "2025-11-26"). If not specified, you must determine the current date.
## Execution Steps
### 1. Initialization & Context Gathering
- **Identify Dataset:** First, list available datasets to confirm the target dataset (e.g., `game_analytics`) exists.
- **Inspect Source Table:** Run a sample query on the source streaming table (e.g., `daily_scores_stream`) to understand its schema. **Crucially, always qualify the table name with the dataset (e.g., `dataset.table`)**.
- **Determine Target Date:** Query the source table to find the latest data date or use the provided date. Confirm this is the date you intend to process.
### 2. Schema Verification
- **Check Historical Stats Table:** Inspect the `player_historical_stats` table to understand its full column structure. This ensures your INSERT query matches the expected schema.
### 3. Core Processing (Execute Both Queries)
Run the following two BigQuery operations. Use the confirmed dataset name and target date (formatted as `YYYY-MM-DD`).
