K10 · bounded transition and assurance evidence

Common-Cause Assurance Analysis

Direct answer

K10 exposes how degraded trusted time, unavailable supplier evidence, or stale recovery evidence can affect multiple mission traces at once, while excluding protected configuration and actionable attack paths.

Authority, operation, and disclosure boundary. K10 publishes static tools, deterministic synthetic fixtures, review queues, offline observation records, migration and merge reports, abstract dependency analysis, reference transition plans, audit trails, signed offline receipts, redaction records, and a release-time dashboard. It does not perform live monitoring, deployment, procurement award, facility certification, network reconnaissance, protected-system operation, legal authorization, or factual adjudication.

Abstract minimal cut sets

The deterministic analyzer identifies bounded sets of shared dependency IDs whose non-satisfied state can degrade multiple traces. It publishes IDs and affected trace counts—not equipment, topology, locations, settings, credentials, response thresholds, or attack paths.

Safety boundary

This is a synthetic assurance dependency model. It is not a threat model for a named facility, an incident report, a vulnerability disclosure, or operational targeting information.
