Verification & evidence

Work that can show it was checked.

We keep records that cannot be quietly changed, give every check a verdict in standard terms, and let an adversary try to break a proposal before a client sees it. Evidence travels with the work.

  • Chained email drafts
  • Specification logs

Verification verdicts

Checked items judged in standard quality terms.

  • Backcheck verdicts
  • Reconciliation dry run

Adversarial gates

A falsifier tries to break the work before release.

  • Falsifier before release
  • Gate checks before elevated work
