BaseScan Preflight / Read-Only Gate

GCA BaseScan Resubmission Preflight

This page is the owner-side gate for the next BaseScan token profile resubmission. It summarizes whether GCA is ready, what evidence is missing, which local checks must pass, and which claims must stay off public materials.

Current result: ready for one owner-controlled resubmission. The Tim Chen professional profile, domain email setup plan, public evidence checklist, remediation tracker, project-domain mailbox, and DNS evidence are ready.

Preflight refresh: the final owner submission package was regenerated on 2026-06-06T11:10:54Z, and this public preflight has been refreshed to match that package.
