Outreach approach

Proposed opening message

Subject: An implementation reference for your policy framework

Dear Christian Holzleitner,

Your role in framing CDR policy has made your published prescriptions an operating specification for implementation work. Trellison Institute has been building a per-tonne open-data verification instrument — the proof pack — that tries to implement that specification.

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
