Proposed opening message

Subject: A multi-scale MRV composition engine for your work

Dear Saskia Keesstra,

Your multi-method MRV framework for nature-based carbon removal has been a design reference for a per-tonne open-data verification instrument that Trellison Institute has been building. We call the artefact a proof pack.

I would welcome a 30-minute conversation to show you the current alpha. We are not asking for endorsement; we are asking for methodology critique and, if useful, an offer of alpha access for your active work. Independent negative evaluations would be published alongside positive ones.

A one-page methodology brief that maps your work to proof-pack schema fields — with gaps flagged honestly — is attached.

With respect,
Rob Stillwell
Director, Trellison Institute
