K12 · differential evidence, reconciliation, and information-flow control

Mission-Thread Stress Laboratory

Direct answer

K12 executes 12 synthetic stress scenarios, blocks promotion in every affected case, and preserves three unresolved coverage gaps without exposing protected architecture.

Evidence and authority boundary. K12 publishes deterministic static models, signed offline reference bundles, synthetic fixtures, review records, custody receipts, public projections, and release-time comparisons. It does not perform live network acquisition, deploy software, operate a facility, make an award, authorize force, certify compliance, enforce production access control, or convert a signature into factual truth.

Claim-level evidence boundary

VERIFIED PROJECT IMPLEMENTATION

Mission stress tests propagate stale and unavailable dependencies

K12 injects deterministic evidence failures and records recovery sequences, affected threads, coverage gaps, and promotion blocks.

Scope: K12 deterministic local reference implementation.

Public fixtures contain no protected facility architecture.

Public failure boundary

The scenarios expose stale, degraded, unavailable, corrected, and withdrawn evidence effects without publishing protected architecture, attack paths, exact thresholds, or facility configuration. They are not real facility exercises or certification evidence.
