How CTK explains every blocked, allowed, and downgraded decision.

Scenario: Operators attempted a restart during high incident pressure.

Contradiction: External health and runtime behavior confidence diverged.

Confidence shift: 0.71 -> 0.43

Decision outcome: Safety Gate blocked restart and required fresh evidence before retry.

Operator meaning: A blocked action means risk posture is not yet safe for high-impact mutation.

Replay summary: Replay chain shows contradiction + freshness penalty crossing block threshold.

Scenario: Runtime anomalies continued while corroborating evidence streams slowed.

Contradiction: Signal quality diverged from expected runtime stability.

Confidence shift: 0.82 -> 0.56

Decision outcome: Recommendations moved from allowed to review state.

Operator meaning: Confidence drop is a trust signal; slow down disruptive remediation.

Replay summary: Replay timeline links each confidence decrement to contradiction persistence.

Scenario: Consumer lag fell after scaling and fresh logs restored evidence quality.

Contradiction: No active contradiction remained in impacted service path.

Confidence shift: 0.59 -> 0.86

Decision outcome: Recommendation moved to allowed under policy threshold.

Operator meaning: Allowed means trust threshold is met, not blind auto-execution.

Replay summary: Replay chain highlights confidence recovery after corroborated evidence alignment.

Scenario: Mapped provider logs stopped updating while incidents remained active.

Contradiction: Stable status claims conflicted with missing diagnostic freshness.

Confidence shift: 0.68 -> 0.49

Decision outcome: Freshness penalty triggered review/blocked actions.

Operator meaning: Stale evidence means trust is decaying even if one signal stream is calm.

Replay summary: Replay graph shows freshness degradation as a direct confidence penalty.

Scenario: A dependency edge disappeared after deploy while request failures increased.

Contradiction: Expected relation map and observed runtime path diverged.

Confidence shift: 0.77 -> 0.51

Decision outcome: CTK downgraded relation trust and gated broad rollback path.

Operator meaning: Topology confidence collapse indicates dependency-level incident risk.

Replay summary: Replay chain maps edge removal moment to confidence degradation timing.

Scenario: Status looked healthy while throughput and consumer behavior degraded.

Contradiction: Health posture and behavior posture could not both be true operationally.

Confidence shift: High -> Medium

Decision outcome: CTK created contradiction state and fed it into adjudication and safety policy.

Operator meaning: Contradiction is explicit conflict modeling, not anomaly noise.

Replay summary: Replay chain shows exactly which evidence branches produced the contradiction node.
