How the work holds together
Because we do not present a roster, it is fair to ask how the work stays dependable. The answer is method, not headcount. The same doctrine we apply to the systems governs how we build them:
Signed authority
Consequential actions in our own tooling are signed and attributable, so decisions have provenance.
Roles and separation
Access follows least privilege and role separation; unknown permissions are denied by default.
Written procedure
Build, release, key management, backup, and incident response are documented procedures, not tacit knowledge.
Reproducible builds
Releases are signed and shipped with a software bill of materials, so what runs can be checked against what was shipped.
Recoverable custody
Key custody uses escrow and threshold recovery, so no single point is unrecoverable.
How we work with institutions
We prefer to work in the open with the relevant authorities rather than develop a unilateral interpretation of our obligations. The goal is technology that is developed locally, auditable, and operable within a clearly defined authorization framework — so that the institution, not the vendor, remains in control.
