data analysis initial exploration

When reviewing or writing code, apply these guidelines:

• Begin analysis with data exploration and summary statistics.
• Implement data quality checks at the beginning of analysis.
• Handle missing data appropriately (imputation, removal, or flagging).

data fetching rules for server components

When reviewing or writing code, apply these guidelines:

• For data fetching in server components (in .tsx files): tsx async function getData() { const res = await fetch('https://api.example.com/data', { next: { revalidate: 3600 } }) if (!res.ok) throw new Error('Failed to fetch data') return res.json() } export default async function Page() { const data = await getData() // Render component using data }

data pipeline management with dvc

When reviewing or writing code, apply these guidelines:

• Data Pipeline Management: Employ scripts or tools like

  dvc

  to manage data preprocessing and ensure reproducibility.

data synchronization rules

When reviewing or writing code, apply these guidelines:

• Implement Data Synchronization:
  • Create an efficient system for keeping the region grid data synchronized between the JavaScript UI and the WASM simulation. This might involve: a. Implementing periodic updates at set intervals. b. Creating an event-driven synchronization system that updates when changes occur. c. Optimizing large data transfers to maintain smooth performance, possibly using typed arrays or other efficient data structures. d. Implementing a queuing system for updates to prevent overwhelming the simulation with rapid changes.

data tracking and charts rule

When reviewing or writing code, apply these guidelines:

• There should be a chart page that tracks just about everything that can be tracked in the game.

data validation with pydantic

When reviewing or writing code, apply these guidelines:

• Data Validation: Use Pydantic models for rigorous

Memory Protocol (MANDATORY)

Before starting:

cat .claude/context/memory/learnings.md

After completing: Record any new patterns or exceptions discovered.

ASSUME INTERRUPTION: Your context may reset. If it's not in memory, it didn't happen.
