K05 assurance architecture

Evidence supports readiness without overclaiming

Direct answer

Every public or procurement readiness state is traceable to exact releases, tests, defects, deployment identity, authority, incidents, uptime, restoration, and independent-verification status.

Evidence boundary. These records describe architecture, control relationships, test requirements, and legal-source status. They do not certify a facility, authorize a mission, prove deployment, or replace current facility-specific engineering and legal review.

Claim

Every public or procurement readiness state is traceable to exact releases, tests, defects, deployment identity, authority, incidents, uptime, restoration, and independent-verification status.

Argument

Architecture, code, a signature, or a successful demonstration proves only a bounded property; evidence must match the claim being made.

Evidence requirements

  • release hash
  • SBOM
  • test coverage
  • defect and waiver records
  • deployment record
  • uptime window
  • incident history
  • independent verification
  • last observation

Assurance defeaters

  • missing artifact
  • stale verification
  • unresolved critical defect
  • unknown deployment identity
  • unavailable incident log
  • marketing statement exceeds evidence

Hazards

  • false procurement confidence
  • unsafe deployment
  • unreviewed residual risk
  • loss of public trust

Recovery objectives

  • downgrade readiness automatically
  • publish correction
  • suspend affected claim
  • restore evidence chain

Site-tailoring questions

  • mission assurance level
  • customer acceptance criteria
  • regulatory recordkeeping
  • classified evidence boundary
