I can't edit anything yet because you haven't added the repository files to the chat.

Please add the relevant files (or the whole repo) so I can fix the 5 issues you requested.
At minimum, please upload:
- TODO.md (so I can see the listed issues) -- I will not modify this file.
- All Python files that TODO.md references, or at least the specific Python files that contain the reported issues.

What I'll do once you upload the files:
1) Inspect TODO.md and the referenced source files.
2) Remove unused imports and duplicate imports (consolidate imports where appropriate).
3) Replace magic numbers with named constants (module-level constants or configuration).
4) Make minimal, well-documented edits and run a quick static-style cleanup.
5) Produce SEARCH/REPLACE blocks to apply each change (one block per edit) and suggest any short shell commands (e.g., tests or linters) you can run.

Please upload the files now (paste file contents or add files). After you do, I'll:
- List the exact edits I'm going to make.
- Provide the SEARCH/REPLACE blocks to apply them.

End.
