## Product Scope

FilePilot demonstrates a controlled file-update workflow. It accepts a target
file description, expected text, and replacement text. The application locates
the file only within an approved demonstration directory, verifies the expected
text, creates a backup, presents a diff, performs the replacement, verifies the
result, and records the outcome.

FilePilot does not provide unrestricted filesystem access, general desktop
control, arbitrary shell execution, or open-ended autonomous planning.

## Demonstration Acceptance Criteria

The demonstration succeeds when FilePilot:

1. finds the approved project-status file;
2. confirms that it contains `Status: Draft`;
3. creates a backup;
4. shows the proposed change;
5. replaces the line with `Status: Reviewed`;
6. verifies the saved result; and
7. records the outcome without exposing secrets.
8. approve the changes
