Outreach approach

A draft opening message previously appeared here. It has been withdrawn from publication and archived internally. No contact has been made. Outreach drafts are not published against a named individual prior to contact and clearance.

What we do not ask for

  • Endorsement of Trellison, LedgerWell, DaedArch, or any affiliated entity.
  • Exclusivity or first-look rights on research findings.
  • Unpaid labour. Any advisor role is compensated with a modest honorarium and disclosed on the record.
