Module 08 Summary

What this module established

Check encoding, emptiness and binary content before a file reaches a prompt. errors="ignore" converts a clear failure into mangled text you will pay to process.

Carry forward

• Split on sentence boundaries. A chunk retrieved alone must make sense alone, which is stronger than fitting.
• Validate extracted records with bounds and patterns before they become rows. A negative invoice amount parses fine.
• List the qualifiers a summary must keep and check mechanically. Brevity and accuracy pull in opposite directions when a statement has conditions.

Before moving on

Move on when your file pipeline rejects three kinds of bad input with distinct reasons, and every answer cites a file and chunk.
