# Example brief: Text file stable unique line filtering

INTERNAL FICTIONAL BRIEFING EXAMPLE — NOT A COMPLETED DELIVERY.

## Intended outcome
Text file stable unique line filtering for one agreed use case.

## Source to supply
Plain text examples, encoding and explicit matching or extraction rules. Remove passwords, tokens and private third-party records you cannot share.

## Maximum starting scope
Up to 5 text files and 50000 lines.

## Example acceptance instructions
1. Identify the exact source items and requested change.
2. Provide one example that should be accepted and one that should be rejected or flagged.
3. Specify the expected destination format and any behavior that must remain unchanged.

## Handoff
Receive the editable implementation or configuration source, local example fixtures, and reproducible verification instructions, an acceptance checklist and a missing-evidence register. The operator must confirm that the actual brief fits this scope before payment.

## Not included
Account access, live deployment, publishing, sending messages, paid external APIs, legal/medical/investment advice, fabricated evidence or guaranteed business results.

## Review questions
- What is the authoritative source version?
- What must the output preserve?
- Which ambiguous cases require your decision?
- How will you inspect the result?
