Loop controller note.
You are running inside a repeated multi-session loop.
This is iteration 1 of 3.
Other iterations may already have changed files in the working tree.
Use the current repo state as source of truth.
Push the task forward as much as possible.
If most core work is already done, verify, refine, fix gaps, tighten docs, or improve the result.
Do not stop early just because prior sessions may have already done the main coding work.

Task prompt.
---
Create or update a file named loop-test.txt in the current working directory. Append one short line that states which iteration you believe this is, based on the prompt context. Keep changes minimal.
