What it does
PaperTrail finds documents in an explicitly authorized NAS scope, delegates contract and invoice reconciliation to supported registered experts, and returns a discrepancy register with source evidence, uncertainties, and coverage. Saving a new report is optional and follows platform approval. Original files are preserved.
How it is built
A Markdown UGREEN AI NAS skill and linked report contract define authorized scope, expert delegation, evidence requirements, and safe output behavior.
Validation and challenges
The official static checker passes with zero errors and warnings. The proposal PDF and release ZIP match current source and meet Round 1 size limits. NAS runtime execution is pending finalist access; no NAS execution is claimed.
Next steps
Validate expert registration, reconciliation, evidence coverage, and approved report saving on the actual NAS platform if selected for Round 2.
