@Shalombonet the composed attribution itself looks sound. Two unrelated files need to come out before this can merge. See inline.

I removed the generated AGENTS.md from the PR and restored the root tsconfig.json.

@Shalombonet the composed attribution path covers the issue's acceptance criteria. Please make the funding-payment id non-breaking, and re-author the commits with an email linked to your GitHub account so they resolve to you. See the inline note.

Thank you for the review @collinsezedike . I’m glad the attribution path and tests cover the acceptance criteria.

Since the merge is clean, could you please merge this PR and close it when you have a moment? I’d also be happy to pick up another open issue afterward.

Thanks again for your time and guidance.
