False Positive Analysis

Control can be valid when owner, scope, expiry, and evidence are explicit. Risk starts when same condition becomes implicit trust or stale exception.

Benign example:

owner=assigned
scope=limited
expiry=tracked
evidence=linked

Coverage Gaps

Missed variant 1: review checks existence but not owner accountability or expiry.

Missed variant 2: exception survives scope change, staff change, or vendor change.

Missed variant 3: evidence proves setup once but not ongoing operation or rollback path.

Edge Cases

• Emergency use can be valid if timeboxed and reviewed.
• Small teams may combine roles but should document reviewer independence limits.
• Vendor systems can delay or omit some audit fields.

Remediation Quality

• Add required fields: owner, scope, trigger, expiry, validation evidence, and rollback path.
• Recheck after identity, tenant, vendor, or architecture changes.
• Fail review when evidence is stale or exception owner is inactive.

Comparison to Other Tools

Point tools catch snapshots. This skill should catch lifecycle drift and missing accountability evidence.

Overall Assessment

Strong base skill. Add database admin path jump-host enforcement gates so review remains useful after initial configuration changes.
